Coating application of crosslinking agent
2017-4-26 22:38:58
Coating application of crosslinking agent,From the traditional ideas, associated with epoxy resin industry chain segment of upper and lower end is a master-slave relationship, the top is fixed, the bottom based on top of product development and application. But from the perspective of modern development, the top also in unceasing innovation. The basis of innovation, is the market demand on the downstream application. In terms of epoxy resin/crosslinking agent, paint industry is one of the most important application areas.
The development of coating: 1, low carbon environmental protection green products; 2, functional products; 3, special products.
Therefore, the development of epoxy resin/crosslinking agent should be towards a low carbon environmental protection material; Functional materials.
The development of coatings industry become an indicator of epoxy resin, crosslinking agent industry. Because epoxy coatings excellent adhesion, resistance to chemical corrosion, thermal stability and colour retention, and many other features, is widely used in automobile, Bridges, ships, especially in steel structure, reinforced concrete shear larger dynamic load or coating.
Epoxy resin itself not crosslinked at room temperature, so it is not practical use value. However, epoxy resin containing active epoxy group in the molecular structure (CH - CH2 -), people take advantage of these active group, with different crosslinking agent of crosslinking reaction, then makes an epoxy resin into insoluble, not fuse with three dimensional network structure of all kinds of high polymer performance characteristics.
In this way, the application of epoxy resin suddenly open space, it is because of its excellent adhesion and sealing ability of corrosive medium, for half a century, are widely used in the corrosion resistance of paint coating of industrial products.
Epoxy resin with what types of crosslinking agent formula, will be in accordance with the coating performance requirements of the design to select, add various fillers and additives, to take advantage of the application of the coating. Therefore, the development direction of epoxy resin, crosslinking agent industry, more attention should be paid to the development of coatings industry trends, crosslinking agent formula for research and development, should be to paint the demand of the market as a guide for design ideas.
The development trends of coating industry. At present, the development of coatings industry, one of the biggest topic is the development and application of green coatings and functional coatings.
In industry, public opinion about green coating has "sink", as the coating raw materials of the upper chain, also should be aligning with the green indicator to match the paint industry, tilted toward features.
Paint industry has/is qualitative change of the structure of products, powder coating, solvent-free coatings, water-based coatings, light crosslinking coatings, etc., it is these changes will promote epoxy resin, crosslinking agent and related the innovative development of the pigments, fillers, additives and new function.
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.
Paint is commonly used in decoration
1, oil: mainly for priming paint before the paint.
2, the original paint: also known as lead, is composed of pigment mixed with drying oil mill, more to be bored with child.
3, mixed paint: also known as mixed paint, oil paint and two types of natural resin paint.
4, varnish: also known as any standing water, oil-based varnish and resin varnish. Varieties have ester gum varnish, phenolic aldehyde varnish, alkyd varnish, nitro qing
5, paint and shellac varnish and so on. Good gloss, film forming fast, widely used.
6, enamel, made with varnish and paint grinding, commonly used with phenolic enamel and alkyd enamel.
7, anti-rust paint: oily antirust paint and resin anticorrosive paint.
8, emulsioni paint, paint film has certain permeability and alkali resistance. Dry film, no bubbles, discoloration, sticky used in interior wall coating. Non-toxic to human body, no pollution to the environment.
