Dispersant features:
First, good dispersion performance
1. It can effectively disperse solid particles such as pigments and fillers evenly in the water phase, prevent particles from agglomerating, and improve the stability of paint, ink and other products.
2. Give full play to the coloring power and hiding power of the pigment, so as to improve the quality of the product.
Second, strong compatibility
1. It has good compatibility with a variety of water-based resin systems and will not adversely affect the performance of the resin.
2. It can be used with other auxiliaries such as defoamer and leveling agent to play a synergistic role.
Third, high stability
1. Under different temperature and pH conditions, it can maintain a good dispersion effect to ensure the stability of product performance.
2. Good storage stability, not easy to stratification, precipitation and other phenomena.
Fourth, good environmental protection
1. Water as a dispersing medium, no organic solvents, reduce environmental pollution and harm to the human body.
2. In line with environmental requirements, it is widely used in water-based coatings, inks and other fields.
Dispersants mainly include the following two aspects:
• Stability mechanism of electrostatic repulsion: the ions produced by ionization of ionic dispersant in water are adsorbed on the surface of pigment particles to form a double electric layer structure. The same charges on the surface of the particles repel each other, thus avoiding agglomeration between the particles and allowing them to be stably dispersed in water. Common anionic dispersants such as carboxylate, sulfate, cationic dispersants such as quaternary ammonium salt, etc.
• Steric stability mechanism: The use of polymeric dispersants whose molecular structure contains anchoring groups and solvated chain segments. The anchoring group can be firmly adsorbed on the surface of the pigment particles, while the solvated chain segment is extended in the water, forming a steric hindrance layer, preventing the particles from getting close to each other and agglomerating. This steric hindrance effect can effectively maintain the dispersion stability of pigment particles. Common polymer dispersants are polyacrylate, polyether and so on.
Overview
Dispersant 5040 High efficiency dispersant is a kind of polycarboxylate sodium salt dispersant with good dispersion and maximum pigment load, which has excellent dispersion for titanium dioxide, calcium carbonate, China clay, etc. The prepared coating has excellent performance, and is suitable for high hydrophobic substances such as organic pigments. The application experiments show that dispersant 5040 has the advantages of small dosage, high efficiency, low viscosity, low grinding viscosity, wide dosage range and good storage stability of dispersion system
Dispersant use object
• Determine the type, nature and particle size of solid particles such as pigments and fillers to be dispersed. Different dispersants have different dispersion effects on different particles. For example, for organic pigments, it may be necessary to select a dispersant with a specific chemical structure to achieve a good dispersion effect; For nanoscale particles, a dispersant that provides sufficient steric hindrance needs to be selected.
• Consider the pH value of the dispersion system. Some dispersants work best in a specific pH range, so the appropriate dispersant needs to be selected according to the pH value of the dispersion system.
2. Application field
1. Clear the use scenario of dispersants, such as water-based coatings, inks, adhesives, etc. Different application fields have different requirements for the performance of dispersants. For example, in water-based coatings, dispersants need to have good water resistance and weather resistance; In inks, dispersants need to be able to improve the coloring power and fluidity of pigments.
2. Consider product performance requirements. If you need a high gloss product, you may need to choose a dispersant that can improve the dispersion uniformity of the pigment; If you need a chemical resistant product, you need to choose a dispersant with appropriate properties.
3. Performance of dispersant
• Dispersion efficiency: Select a dispersant that can quickly and effectively disperse particles into water to improve production efficiency. The dispersion effect of different dispersants can be tested experimentally, such as observing the system stability and particle size distribution after dispersion.
•Stability: The dispersant should be able to maintain the stability of the dispersion system under different temperatures, pH values and storage conditions to prevent particles from reuniting. Accelerated aging tests can be performed to evaluate the stability of the dispersant.
•Compatibility: Dispersant should have good compatibility with other components in the system, such as resins and auxiliaries, to avoid adverse reactions. When selecting dispersants, compatibility tests can be carried out to observe whether there are precipitation, stratification and other phenomena.
•Environmental protection: priority is given to environmentally friendly dispersants, which do not contain harmful substances and meet relevant environmental standards. Safety data sheets and environmental certifications for dispersants can be reviewed to assess their environmental performance.
Fourth, the cost factor
1. Consider the price and amount of dispersant used. The price of different types of dispersants varies greatly, and the amount of use will also affect the cost. Under the premise of satisfying the dispersion effect, selecting the dispersing agent with reasonable price and less use can reduce the production cost.
2. Consider the performance and cost of dispersant comprehensively, and choose cost-effective products. Do not only pursue low prices and ignore the performance of the dispersant, and do not blindly choose high prices of dispersants and lead to high costs.
Advantages of dispersant:
1. Environmental protection: water as a solvent or dispersion medium, does not contain organic solvents, reduce the organic solvent volatilization of environmental pollution and harm to human health, in line with environmental requirements, help to promote the paint, ink and other industries to green environmental protection direction.
2. Safety: Most water-based dispersants are non-toxic or low toxic, and are relatively safe during production, use and storage, reducing safety risks.
3. Good dispersion performance: can be adsorbed on the surface of particles, through electrostatic repulsion, steric hindrance and other effects, so that pigments, fillers and other particles in the water-based system evenly dispersed, prevent particles agglomeration, precipitation, improve the stability of the dispersion system. For example, in water-based coatings, the pigment can be evenly dispersed to ensure the color uniformity and hiding power of the coating.
4. Good compatibility with water-based system: especially suitable for water-based coatings, water-based inks, water-based adhesives and other water-based systems, can be well compatible with other components in the system such as resins, auxiliaries, etc., does not affect the overall performance of the system.
5. Reduce viscosity: It can effectively reduce the viscosity of the system, improve the fluidity, make it easier to stir, transport and coating in the production process, and improve production efficiency. At the same time, in the construction process, it can also make the paint, ink, etc., easier to paint, spray or print, and obtain better construction results.
6. Improve the color development and coloring power of the pigment: help the pigment fully show its color and hiding ability, make the color more vivid, bright, and improve the appearance quality of the product.
7. Prevent floating colors and flowers: It can reduce the migration and accumulation of pigments in the system, avoid floating colors, flowers and other phenomena, and ensure the appearance uniformity of the coating or printed matter.
8. High stability: It can improve the storage stability of the dispersion system, prevent particles from settling and caking during storage, and extend the shelf life of the product.
9. Wide applicability: It can be used for the dispersion of a variety of different types of pigments and fillers, such as organic pigments, inorganic pigments, carbon black, etc., and has a good dispersion effect on different water-based systems.
10. Adjustability: by selecting different types and molecular weights of water-based dispersants, as well as adjusting the amount of dispersants, the dispersion effect can be adjusted and optimized according to the specific application needs and formula requirements.
