Emulsion General properties
Vinyl acetate ethylene copolymer emulsion, referred to as emulsion, is a milky white liquid. The emulsion has internal plasticity due to the ethylene comonomer and has good film-forming properties, weather resistance, adhesion, broad compatibility, weak acid and alkali resistance and other properties.
Main uses of emulsion
Adhesive base material
Emulsion can be used as an adhesive material for wood and its finished products, paper and products, packaging composite materials, plastics, buildings, etc.
, coating base material
The emulsion can be used as the base material for interior wall coatings, elastic coatings, roof and underground waterproof coatings, fireproof and thermal insulation coatings, and can also be used as the base material for building caulking and sealing adhesives.
, paper sizing and paper glazing
Emulsion can be used for a variety of sizing and glazing, and is an excellent material for manufacturing various types of high-grade paper.
, non-woven fabric adhesive
Emulsion can be used as the base material for non-woven fabric adhesive.
, cement modifier
The performance of cement products can be greatly improved by incorporating emulsion into cement mortar.
, carpet adhesive
The emulsion can be used as an adhesive for tufted carpets, needle punched carpets, woven carpets, artificial fur, artificial grass, electrostatic flocking, advanced building assembled carpets, etc.
Emulsions are mainly used in adhesives, coatings, cement modifiers and paper processing and have many excellent properties.
The lotion is permanently flexible. The emulsion can be regarded as an internal plasticized product of the polyvinyl acetate emulsion. Because it introduces the ethylene molecular chain into the polyvinyl acetate molecule, it creates discontinuity in the acetyl group and increases the rotational freedom of the polymer chain. The space hinders the deformation of the small polymer main chain. It is soft and does not undergo plasticizer migration, ensuring that the product is permanently soft.
The emulsion has good acid and alkali resistance. The emulsion can maintain stable performance in the presence of weak acids and weak bases, so it will not break down regardless of whether it is mixed with weak acids or weak bases. The product has a wide range of applications.
The emulsion is resistant to UV aging. Since the emulsion uses ethylene as the internal plasticizer of the copolymer, the polymer has internal plasticity and the plasticizer will not migrate, thus avoiding the aging of the polymer properties. Therefore, not only does the emulsion have good stability against ultraviolet rays, but this characteristic can also be maintained after the emulsion is filmed.
The emulsion has good film-forming properties. Emulsion adhesives can only form a transparent film at a certain temperature. This temperature is called the minimum film-forming temperature. The minimum film-forming temperature is generally lower than ℃, so it can form a good film and the film has good barrier properties against water droplets.
The emulsion has good adhesion. It has a good bonding effect on fiber, wood, paper, plastic film, aluminum foil, cement, ceramics and other products.
According to the waterproof properties of emulsion polymers, they can be divided into two categories: general purpose and waterproof. The polymers of general-purpose product grades have good rigidity and high adhesive strength but poor water resistance. The polymers of waterproof product grades have good flexibility and good water resistance but low bonding strength. According to application performance, copolymer composition and copolymerized third monomer type, emulsions can be divided into two categories: sticky products and textile products. The adhesive type is mostly used as a general-purpose adhesive, while the textile type adhesive is mostly used as an adhesive for textile fibers. However, there is no absolute boundary between the two.
Because emulsions have many excellent properties, they are widely used in practical applications.
Emulsions are widely used as base materials for adhesives. The emulsion has good mechanical properties. The average particle size of the emulsion particles is small. There is a good balance between creep resistance and heat sealability. It has good wet viscosity and fast curing speed. The emulsion has a wide range of bonding properties. In addition to being able to bond wood, leather, fabric, paper, cement, concrete, aluminum foil, galvanized steel plates and other materials, the emulsion can also be used as a pressure-sensitive adhesive and heat sealant. It can also be used for some difficult-to-bond materials such as Films such as polyethylene, polypropylene, polyvinyl chloride, and polyester have unique adhesive properties.
Emulsions can be used as base materials for paints. Paints made with polyvinyl acetate emulsion, acrylic emulsion, emulsion, styrene-butadiene emulsion, propylbenzene emulsion, acetobenzene emulsion, etc. as base materials are collectively called latex paint. Latex paint can be used as interior and exterior wall coatings, roof waterproof coatings, fire retardant coatings, and anti-rust coatings. The latex paint film has good blistering resistance, is resistant to aging and is not prone to cracking. It has good adhesion to a variety of substrates. It is safe, non-toxic and easy to use. Latex paint can not only be coated on wood, masonry and concrete, but also on metal, glass, paper, and fabric surfaces. It has a good affinity with paint and can be painted on each other's surfaces.
