Waterborne acrylic acid resin coating used crosslinking agent
Acrylic emulsion, acrylic emulsions), due to its generality, weatherability and diversity, it has been widely in the areas of coating industry application.
Water-based acrylic emulsion is formed by emulsion polymerization of vinyl monomers dominated by acrylic ester monomer. The polymerization process includes emulsifier, stabilizer, pH modulator and other auxiliaries, and the system is quite complicated.
The paint film made of water-based acrylic emulsion has good weatherability, not easy to yellow hair, high hardness and good gloss. In recent years, with the continuous development of water-based acrylic emulsion polymerization technology, heterogeneous polymerization, the core-shell technology, since the crosslinking technology and application of polymeric surfactants, and core-shell polymerization technology improvement and further improve the properties of waterborne acrylic emulsion, and that the water-based acrylic emulsion adapt to different construction and the needs of the conditions of use, place continuously expanding. Now, the application of water-based acrylic emulsion has been extended to more industrial USES.
A variety of oils and oils
Oil: oil or fish oil. Its advantages are low price, low odor, convenient construction and long storage period. Can be painted on wood, metal surface, as waterproof, moisture-proof coating, mainly used for thickening lacquer, putty. The drawback is that the drying is slow, the paint film is soft, and the resistance is poor.
Heavy paint: the advantage is that it is smaller than the general paint, the packaging, storage, transportation cost is low, the construction is convenient, the price is cheap, can be freely deployed. The disadvantage is that there is more body paint, because it is mixed with oil, the weather is poor, the quality cannot be controlled well, and it is often used as the decoration of the building works.
Mixed paint: it is divided into two kinds: oil blending paint and magnetic adjustment. The adhesion of oil blending paints is not easy to fall off, it can't be cracked, not easily powdery and durable, but it has a slow drying, soft paint film, poor weather resistance and suitable for indoor and outdoor painting of general buildings. The dry sex ratio of magnetic adjustment paint is better than oil, the paint film is harder, the light is smooth, but the weather resistance is worse than the oil blending paint, easy to lose the light crack, generally used in interior painting.
Chinese name: Diethyl toluene diamine(DETDA)
Diethyltoluenediamine Uses:
The product is identical to Ethancure 100 and Lonza DETDA 80, DETDA is very effective polyurethane elastomer chain extender; also be used as polyurethane and epoxy resin curing agent, epoxy resin of an antioxidant, industrial oils and lubricants . In addition, also as intermediates in organic synthesis.Especially for the RIM (reaction injection molding), is important in the field of spray polyurea chain extender species. Also can be used for casting polyurethane elastomer (CPU) and a curing agent, epoxy curing agent, epoxy resin of antioxidants, lubricants and industrial oils other antioxidants.
Anti-rust primer: good rust resistance, quick drying, high power, high mechanical strength and good water resistance. The disadvantage is that the lumps are serious and not easy to be sprayed. It is used for anti-corrosive primer for black metal outside. General light metal (aluminum, zinc) anti-rust paint can be used zinc flavanol acid anti-rust paint, but can only be used in the bottom, not to be used in the paint, also not applicable to black metal.
Natural resin paint is made of dry vegetable oil and natural resin. It can be divided into varnish, enamel, primer and putty. The dry oil in natural resin paint increases the flexibility of the paint film, and the resin makes the film improve the hardness, gloss, fastness and the bent. The paint film has a better performance than grease paint.
In the paint, oil and resin ratio is also important, the paint oil content has a great influence on the performance of the film. When the proportion of resin and oil is below 1:2, it is called short oil paint, its characteristic is the paint film is dry quick, the gloss is good, hard wear-resisting, but the resistance is not good, it is suitable for indoor coating only.
The ratio of resin and oil is at 1:3, and the oil paint is characterized by soft paint film, flexible and glossy, with improved weather resistance and slow drying of paint film, suitable for outdoor use. The ratio of resin and oil in 1:2 ~ 1:3 is said to be the oil paint, its performance in between the first two, indoor and outdoor can be available.
Natural resin paint is characterized by simple construction, low cost, easy material, good decorative and protective effect. The disadvantage is that the durability is not good, directly exposed to atmospheric conditions, the loss of light and powder in half a year. The other drawback is that a considerable amount of vegetable oil is used in the paint. Natural resin paint is widely used in civil buildings, wooden furniture and so on, is a kind of coating commonly used nowadays.
