Polyurethane powder coating flame retardant
Polyurethane powder coatings (PU powder coatings) are thermosetting powder coatings composed of hydroxyl resins, blocked isocyanates, pigments, fillers and additives.
This kind of powder coating can also be regarded as a special variety of polyester powder coatings, that is, hydroxyl polyester resin cured by closed isocyanate powder coating system.
Phosphorus flame retardant polyurethane powder coatings with low halogen and halogen-free, low smoke and low toxic properties, the less dosage, high efficiency, have attracted considerable attention in the field of flame retardant polyurethane powder coatings, with great development potential and space in china. However, due to some defects of phosphorus flame retardants, the research of phosphorus polyurethane powder coating flame retardant needs to be strengthened.
For the blocked polyisocyanate curing agent of polyurethane powder coatings, the isocyanate with aliphatic and aromatic two kinds of aromatic polyurethane powder blocked polyisocyanate curing yellowing resistance and corrosion resistance is better, but the weathering resistance and yellowing of baking powder and the performance is not good, the price is expensive, and the characteristics of epoxy powder paint cheap is not much more prominent.
The other is made of polyurethane powder coatings for physical and mechanical properties of polyurethane powder coating weatherability curing agent of aliphatic blocked polyisocyanate curing and coating and chemical performance is relatively good, is the main varieties of weather-resistance powder coating. The weather resistance polyurethane powder, polyurethane powder coating the most used curing agent is closed isophorone diisocyanate (IPDI).
The polyurethane powder curing agent system, the reaction temperature determines the closure temperature of solution sealant, commonly used to add catalyst to reduce the temperature and reduce the curing temperature of closed solution, catalyst addition amount of curing agent about 1% can reduce the baking temperature of 10 degrees celsius. Different NCO content IPDI glass transition temperature and the melting range and closed temperature had some effect.
The curing temperature of polyurethane powder coating should be higher than 170 degree of curing agent to solve the sealing temperature. In order to obtain satisfactory physical and mechanical properties of the coating, the curing conditions should be carried out at 180 *20min or 200 *10min.
Amine curing agent is a kind of organic polyamine as curing agent of epoxy resin compound, commonly used in the production of thermosetting resin laminate, epoxy anticorrosive paint, floor paint, composite material products in the manufacturing industry, construction industry, automobile industry, marine industry and aerospace and other fields have a wide application.
Powder coating is one of the most environmentally friendly coatings, the most rapid development. The polyurethane powder coatings and acrylate powder coatings with good weatherability and decorative properties have great space for development. Most of the thermosetting powder coating is the need to use the curing agent.
The matching of curing agent and resin is very important for the storage stability, curing speed, construction leveling performance, film appearance, mechanical properties and weather resistance of paint film.
Tris(2-chloroisopropyl)Phosphate(TCPP)
Cas No:13674 -84-5
HS Code HS: 29199000
The most important indicator of product:
colorless transparent liquid, moisture ≤ 0.1, Acid value ≤ 0.1, Chroma ≤ 50, the phosphorus content: 9.4 ± 0.5
Raw materials: phosphorus oxychloride and epichlorohydrin.
Belong to several categories of dangerous goods:
Currently Tris(2-chloroisopropyl)Phosphate TCPP general cargo exports are not dangerous.
The product is used for the soft / hard polyurethane foam, with thermal and hydrolytic stability good, especially suitable for ASTME84 (Level 11) foam, with low viscosity unsaturated polyester resin in low temperature application and phenolic plastics at. This product is also used to grab the foam sealant and sheet production. For polyvinyl chloride, polystyrene, phenolic resin, acrylic resin and rubber, coating, flame retardant, also used for soft and hard polyurethane foam, epoxy resin, polystyrene, cellulose acetate, ethyl cellulose tree and phenolic plastics, polyvinyl acetate and gun type foam sealant production. Particularly recommended for rigid polyurethane foam has excellent thermal and hydrolytic stability is particularly suitable for ASTM84 (II), compound for polyurethane foam and unsaturated resin and phenolic plastics.
Coating usually consists of film forming material, pigment, solvent and diluent, auxiliary agent. After coating construction, with the evaporation of solvent and diluent, the film is dried into film. Film forming materials can be formed separately, or can also bind pigments and other substances to form a film together, so it is also called binder. It is the coating foundation, often referred to as the base material, paint and paint base.
Paint additives can be divided into oily coating additives and additives for waterborne coatings. With the global increasing emphasis on environmental protection, the development of waterborne coating additives has been developed rapidly. More and more new type of environmental protection auxiliaries, more and more widely used, is the main direction of the development of coating additives in the future.
Polyurethane powder coatings with aliphatic closed polyisocyanate cured have many advantages. Worldwide, the production of polyurethane powder coating is the second place weather resistant powder after polyester powder coating, and the proportion of Japan in the proportion of powder coatings is the highest in Japan, followed by the United states.
In recent years, with the development of the furniture industry, the process of wood grain transfer printing is rising, and the excellent performance of polyurethane powder coating in the process of transfer printing is recognized by the industry, thus further guiding the industrial demand.
Polyurethane resin (hydroxyl resin) in polyurethane powder coating, film material is a polyester resin and a blocked polyisocyanate curing agent, wherein the polyester resin is hydroxyl terminated polyester resin, its hydroxyl value range is 25~30mgKOH/g, his range is very wide, between the hydroxyl value of polyester polyester high and low hydroxyl value each other, can preparation of extinction powder coating.
The hydroxyl value of polyester resin used in general PU powder coatings is mostly 25~56mgKOH/g, the softening point range is 100~125, and the glass transition temperature is 57~68. Varieties and specifications of hydroxyl resin is more.
Polyurethane powder coating is becoming mainstream of powder coatings, powder coatings accounts for an increasing proportion of the polyurethane powder coating with excellent weatherability, excellent mechanical properties and corrosion resistance, coating, wear resistance, bright scratch resistance, solvent resistance, good leveling, strong adhesion. At present, it is widely used in refrigerators, washing machines, air conditioners and other household appliances and advanced furniture, automobiles, motorcycles and other industries.
