Aqueous EVA resin emulsion is a polymer emulsion composed of ethylene (E) and vinyl (VA) monomers copolymerized by emulsion polymerization with water as dispersion medium. Here is a detailed description of it:
1. Basic features:
• Good flexibility: Due to the introduction of ethylene molecular chain in polyvinyl molecules, the polymer main chain becomes soft, increases the molecular chain's rotational freedom and space obstruction is small, and does not occur plasticizer migration, ensuring that the product is permanently soft.
• Good acid and alkali resistance: it can maintain stable performance under the presence of weak acid and weak base, and will not break milk when mixed with weak acid or weak base, and the product has a wide range of applications.
• UV aging resistance: ethylene is used as the internal plasticizer of the copolymer, so that the polymer has internal plasticizer, the plasticizer will not migrate, not only EVA emulsion has good stability to UV, but also can maintain this feature after film formation.
• Good miscibility: It can be directly mixed with most additives, pigments, fillers, and many low molecular and high molecular water-soluble polymers, other polymer emulsions, aldehydes, esters, ketones, organic acids, polyols, etc., to meet various different needs.
• Good film forming: The lowest film forming temperature is generally lower than 5ºC, which can form a good film, and the skin film has a good barrier to water droplets.
• Strong adhesion: fiber, wood, paper, plastic film, aluminum foil, cement, ceramics and other products have a good bonding effect, for some difficult to bond materials such as polyethylene, polypropylene, polyvinyl chloride, polyester and other films is unique adhesion.
2. Application field:
• Adhesive: It is an important base material for adhesives, which can be used for bonding wood, leather, fabric, paper, cement, concrete, aluminum foil, galvanized steel plate and other materials, and can also be used as pressure sensitive adhesive and heat sealing adhesive.
• Coating: can be used as the base material of coating, used in the manufacture of interior and exterior coating, roof waterproof coating, fireproof coating, anti-rust coating and so on. EVA latex paint coating film has good foaming resistance, aging resistance is not easy to crack, and has good adhesion with a variety of substrates, safe and non-toxic, easy to use.
• Paper processing: mainly used for paper impregnation, paper coating and pulp addition, can give a variety of paper glazing, increase the dry and wet strength of paper, toughness, gloss, improve color stability, reduce ink printing consumption, improve paper grade.
• Cement modification: It can improve the shortcomings of cement products easy to crack and water resistance, impact resistance and poor acid resistance, and is widely used in civil engineering as a new material.
3. Storage and Transportation:
• Store in a cool, dry and well-ventilated place, away from direct sunlight and high temperatures. At the same time, pay attention to moisture and fire prevention to ensure product quality and safety.
• In the process of transportation, to prevent packaging damage, leakage, to avoid mixing with other chemicals.
Water-based EVA resin emulsion has the following advantages:
1. Good flexibility: After the ethylene molecular chain is introduced into the polyvinyl molecule, the polymer main chain becomes soft, the molecular chain of rotational freedom is increased and the space obstacle is small, and the plasticizer migration phenomenon does not occur, ensuring the permanent softness of the product. This flexibility makes the water-based EVA resin emulsion can adapt to the deformation and movement of different materials in the application, and is not easy to break or crack.
2. Good acid and alkali resistance: it can maintain stable performance under weak acid and weak base conditions, and will not break milk when mixed with weak acid or weak base, so it can be used in a variety of different pH environments to expand its application range.
3. Ultraviolet aging resistance: The use of ethylene as the internal plasticizer of the copolymer, so that the polymer has internal plasticizer, the plasticizer will not migrate, so not only the water-based EVA resin emulsion itself has good stability to ultraviolet light, its film can also maintain this feature, can be used for outdoor environment or long-term exposure to the sun application scenarios.
4. Good miscibility: It can be directly mixed with most additives, pigments, fillers, and many low molecular and polymer water-soluble polymers, other polymer emulsions, aldehydes, esters, ketones, organic acids, polyols, etc., which can meet the needs of different formulations and facilitate adjustment and optimization according to specific applications.
5. Good film forming: The lowest film forming temperature is generally lower than 5 ° C, which can be well formed at a lower temperature, and the skin film has a good barrier to water droplets. This makes water-based EVA resin emulsions advantageous in low-temperature environments or in applications where water resistance is required, such as in architectural coatings, waterproof coils, etc.
6. Strong adhesion: fiber, wood, paper, plastic film, aluminum foil, cement, ceramics and other products have a good bonding effect, for some difficult to bond materials such as polyethylene, polypropylene, polyvinyl chloride, polyester and other films is unique adhesion. Therefore, it is widely used in adhesives, coatings, paper processing and other fields.
7. Safety and environmental protection: water as a dispersive medium, does not contain organic solvents, compared with some solvent-based resin emulsion, water-based EVA resin emulsion in the production, use and storage process of less harm to the environment and human body, in line with environmental protection requirements.
8. Low cost: wide source of raw materials, relatively simple production process, and low energy consumption in the production process, making the cost of water-based EVA resin emulsion is relatively low, with a high cost performance.
Water-based EVA resin emulsion storage needs to pay attention to the following points:
First, environmental requirements
1. Suitable temperature: should be stored in a cool place, the temperature is generally controlled between 5 ° C and 35 ° C. High temperature may lead to deterioration, thickening and even gelation of the emulsion. Too low temperature may make the fluidity of the emulsion worse and affect the performance.
2. Moderate humidity: The relative humidity of the storage environment is best controlled below 60%. Excessive humidity may cause the emulsion to absorb water, which affects its performance and stability, and may even cause the emulsion to break.
2. Packing and sealing
1. The original packaging is sealed: ensure that the emulsion is well sealed in the original packaging drum or container. After use, the lid of the barrel should be closed in time to prevent air, moisture and impurities from entering. If the packaging drum leaks, it should be replaced in time or remedial measures should be taken.
2. Avoid opening too large: When using, you should try to avoid opening too large to reduce the contact area between emulsion and air. You can use a special extraction tool to avoid direct hand contact with the emulsion.
Third, prevent pollution
1. Away from pollution sources: The storage place should be away from dust, oil, chemicals and other pollution sources. Avoid contamination of the emulsion, affecting its performance and use effect.
2. Separate storage: It is best to store water-based EVA resin emulsion separately to avoid mixing with other chemicals. Different chemicals may interact, causing the emulsion to deteriorate or fail.
Fourth, regular inspection
1. Appearance inspection: Check the appearance of the emulsion regularly to observe whether there are abnormal phenomena such as discoloration, delamination, precipitation and gel. If any exception is found, handle it in time or consult the supplier.
2. Viscosity detection: The viscosity of the emulsion can be tested regularly with a viscometer to ensure its stable performance. If the viscosity changes significantly, it may mean that the emulsion has deteriorated or become contaminated.
5. Use within the warranty period
Apply lotion strictly according to the shelf life on the product instructions. During the shelf life, the performance and quality of the emulsion are relatively stable. If past the expiration date.
