Paint USES room temperature crosslinking agent
In the process of membrane drying, the pH value of the system was decreased and the membrane of high crosslinking degree was obtained.
At room temperature crosslinking technology is developed, which brings new life to the development of latex coating. Compared with the higher temperature, the crosslinking reaction system has obvious advantages. Not only the film has a stable crosslinking structure, but also need not be heated in the construction, save energy, greatly expanded its application scope. The disadvantage is that the price of functional monomer is more expensive, and its cost is high, so that its application is limited.
Latex paint, commonly known as latex paint, is a kind of water-based coating, which is based on synthetic polymer milk, and disperses the pigment, stuffing and auxiliary agent into the water dispersing system.
It is the earliest latex paint that is made of latex made of butadiene and styrene. Mainly for internal use of architectural paint. However, due to its brittle and brittle paint film, it has been replaced by the square root of polyvinyl acetate latex paint.
Polyvinyl acetate latex paint is the most widely used latex paint, made of latex made from vinyl acetate. As an indoor grey wall paint, it has good color retention and adhesion. It also has a certain degree of resistance to outdoor use, and in order to make the paint film not crack and powdery, it can improve the flexibility of the paint film by using butadibutyl butylenate as toughening agent. This kind of lacquer also has certain adhesion to wood surface and old paint film.
Acrylic latex paint is made from some acrylic acid - fat copolymer. Due to different kinds of acrylic copolymer, different kinds of latex paint can be obtained. Because acrylic latex paint has the soft paint film, the ability to withstand water and alkali resistance, good outdoor weather resistance, and the adhesion of the coating to the main characteristics, so often as outdoor wood surface and plaster surface architectural paint.
Oil-based emulsion paint is composed of dry vegetable oil, rosin glycerin, emulsifier and drier. It has certain oil resistance, insulation and can be used as insulating paint. Because the storage stability is bad, the general is made the paint base, when use, emulsification. There is also a powder emulsion paint, which has the advantages of long storage and convenient transportation.
Basic composition of latex coating: base material (latex), pigment and filler, auxiliary agent 3.
The properties of latex paint are determined by the properties of the emulsion, and the additives and solvents improve the performance and operation of emulsioni paint.
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.
Latex is mainly composed of resin, emulsifier and protective adhesive, acid and alkalinity regulator, digestant and toughening agent.
The pigment slurry is the water dispersion which is ground by the paint, the pigment and the various auxiliaries. The vast majority of emulsioni paint is white and light color, general with strong covering power of titanium white as the main pigments, and use the proper number of inert pigment (such as talcum powder) to control the liquidity of the finished product, at the same time improve the water resistance, abrasion resistance and other performance of paint.
In the pigment slurry, also add a certain dispersant, make the pigment easy to disperse in the water and prevent the paint film to be thick. In addition, in order to prevent the accumulation of particles, so as to avoid the effect of brushing and leveling and the occurrence of falling, the thickening agent should be added.
Add anti-mildew agent, antirust agent, antifreeze and so on in emulsioni paint, still have water in the aid. Generally use pure water, the best use of soft water or distilled water, because the impurities in hard water will affect the stability of the latex system.
The preparation of latex lacquerware is generally divided into two steps, the first step is to add the pigment, dispersant and the right amount of ash to the dispersing machine, dispersing into the proper fine amount of pigment pulp. The second step is to mix the pigment slurry with latex in the mixer to form the paint, and other auxiliary materials are also added when the paint is being painted.
Because latex paint is a complex heterogeneous system, the film process is different. When the latex paint is painted on the surface, the water evaporates first, while the globular particles scattered in the water are close to each other. With the continuous evaporation of water and the effect of plasticizer, the globular granules are compressed to become more compact and finally form continuous coating.
