Polyurethane resin flame retardant
Polyurethane resin has become a common raw material for high end coatings due to its excellent comprehensive properties. Polyurethane resin flame retardant is commonly used in polyurethane additives.
Polyurethane resin flame retardant, flame retardant products for soft and hard polyurethane foams. Flame retardant material made of polyurethane resin flame retardant has excellent thermal conductivity and flame retardant efficiency.
Isocyanate isocyanate curing agent in the group activity is very high, in the preparation of powder coating process need to adopt BH sealant curing isocyanate group in closed again when. Isocyanate curing agent for the use of multiple diisocyanate (HDI) or (isophorone diisocyanate) trimer or oligomer IPDI etc..
The use of blocked isocyanate curing agents is curing when sealant leave system, affect the compactness and paint some pollution problems. In order to reduce the amount of sealant, self shrinkage formation of biuret two ketone structure also can be used IPDI, biuret two ketone at a certain temperature can re release solution of isocyanate groups.
The two ethyl carbonyl compound, malonic acid two ethyl ester, can be blocked by isocyanate and cured at 120-140 degrees low temperature. It can be used in epoxy and its mixed formula. It is a very promising low temperature curing agent.
Oxime (with butanone oxime general) blocked isocyanate curing precipitation, no oxime, unpleasant smell, low curing temperature, and hydroxyl terminated polyester with polyurethane for powder coating, but the existence of yellowing problem.
Isocyanate is the floorboard of various esters of isocyanate. According to the number of NCO groups, including isocyanate R - N=C=O and diisocyanate O=C=N - R - N=C=O and polyisocyanate.
Isocyanates are important intermediates in organic synthesis, which can be used to produce a series of carbamate insecticides, fungicides, herbicides, and also to improve the water resistance of plastics, fabrics, leather and so on. Two functional groups and above isocyanate can be used to synthesize a series of polyurethane foam, rubber, elastic fiber, coating, adhesive, synthetic leather, artificial wood and so on.
At present, the most widely used and the largest output are: Toluene Diisocyanate (TDI); two Methylenediphenyl Diisocyanate (MDI).
Toluene diisocyanate (TDI) as a colorless pungent flavour liquid, the boiling point of 251 DEG C, the proportion of 1.22, light black, have a strong stimulating effect on the skin, eyes, and can cause eczema and asthma, mainly used in polyurethane foam, coating, synthetic rubber, insulation paint, adhesive etc.. According to its composition, toluene diisocyanate is an organic compound containing nitrogen group.
Tris(2-chloroisopropyl)Phosphate(TCPP)
The production process of flame retardant TCPP with the following steps:
(1) to three phosphorus oxychloride and epichlorohydrin by phosphoric acid, three in catalysis of AlCl3 (2, 3- two Lv Bingji) ester mixture.
(2) added to the mixed solutions of alkali, alkali washing to neutral, static stratified, removing water; reservoir water again after the static stratified, removing water, reservoir after distillation liquid phosphoric acid three (2, 3- two Lv Bingji) ester, and the nitrogen gas purification. This process has the advantages of simple preparation process, to produce phosphoric acid three (2, 3- two Lv Bingji) ester as compared with the existing production process of high purity, its quality detection results were better than the existing technology in the production process to produce phosphoric acid three (2, 3- two chloropropyl) ester.
Process the above description of the product, such as the flame retardant TCPP production technology to further understand please contact us.
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.
Two phenyl methane diisocyanate (MDI) can be divided into pure MDI and crude MDI. Pure MDI is a white solid at room temperature. It has a pungent odor at heating and boiling point of 196 degrees C. It is mainly used in rigid polyurethane foam, synthetic fiber, synthetic rubber, synthetic leather, adhesives and so on. According to its composition, pure two phenyl methane diisocyanate is also a nitrogen-containing organic compound.
There is also a non yellowing variant of 1,6- diisocyanate (HDI).
The industry is mainly using primary amine phosgene isocyanate production, the reaction is as follows: two by amine phosgene can be prepared with diisocyanate: the progress of science and technology and the synthesis of the development of the theory, process and synthesis of nitro compounds and direct carbon monoxide catalyzed isocyanate at high temperature and high pressure is more and more mature.
A generic term for various esters of isocyanates. There is an isocyanate R - N=C=O and diisocyanate O=C=N - R - N=C=O. Usually unpleasant smelling liquids. An isocyanate is easy to react with ammonia or amines to form urea, which is easy to react with alcohol to form carbamates (such as ethyl carbamate).
Powder coatings are completely different from general coatings, which exist in the state of fine powders. Because of no use of solvents, it is called powder coating. The main characteristics of powder coatings are: harmless, high efficiency, saving resources and environmental protection features.
There are two main categories: thermoplastic powder coatings and thermosetting powder coatings.
Thermoplastic powder coatings are composed of thermoplastic resins, pigments, fillers, plasticizers and stabilizers. Thermoplastic powder coatings include polyethylene, polypropylene, polyester, polyvinyl chloride, chlorinated polyether, polyamide, cellulose, polyester series.
Thermosetting powder coatings are composed of thermosetting resins, curing agents, pigments, fillers and additives. Thermosetting powder coatings include epoxy resin series, polyester series and acrylic resin series.
There are many classification standards, and the names of all kinds of powders are uneven. According to the properties of film-forming materials, they are divided into two categories: thermoplastic powder coatings and thermosetting powder coatings. Or the appearance of film forming material is divided into extinction type, high light type, art type and so on. It can be divided into two types: indoor and outdoor.
