Unsaturated resin UPR flame retardant
UPR processing performance, simple technology, can be a forming, as well as atmospheric pressure forming, heat and pressure curing, and no low molecular by-products generated in the process of curing, can produce more uniform product. Due to its excellent process performance, it has been widely used in recent years to make handicrafts, imitation marble products, polyester lacquer and other non-glass fiber reinforced materials.
Upr-frp is a compound material of UPR and glass fiber reinforced bone material. The two products are processed into the final shape. So FRP is not only a material, but also a structure. There are two aspects to the so-called design-ability:
(1) functional design; By selecting proper UPR and glass fiber, FRP products with various special functions can be made, such as: can be made into corrosion resistant products; It can be made into an instantaneous high temperature product; Can be made of transparent sheet; Can be made of refractory flame retardant products; Can be made of uv resistant products.
(2) structure design: the structure of various products can be designed flexibly according to the needs, such as glass and steel doors and Windows, glass steel grille, glass steel pipe, glass steel tank, glass steel tank, etc.
Unsaturated resin and UPR the aromatic bromide flame retardants such as tetrabromobisphenol A, ten bromide (eight bromide) diphenyl ether, etc. It has excellent heat resistance, in the field of polymer material flame retardant has important industrial value, market demand is very big.
The fat family of unsaturated resin UPR flame retardants, such as dibromoprene and its derivatives, have attracted much attention in recent years due to their high optical stability and anti-ultraviolet properties.
When the polymers are burning in the air, the hydrocarbons are under the action of oxygen, because the thermal decomposition produces the reactive radical H0. , H0? The burning speed is determined, so to stop the polymer burning, you have to reduce HO? Concentration, and HBr happens to be easy to deal with free radicals H0? The reaction generates H20 and the less reactive Br? It can be a flame retardant.
Tris (1,3-Dichloro-2-Propyl) Phosphate (Flame Retardant TDCPP)
(A Small Cabinet Loaded With 16 Tons), 1000KG / IB Bucket (A Small Cabinet Installed 18 Tons) Or 23 Tons (1, 3-Dichloro-2-Propyl) Phosphate (TDCPP) Packing: Net Weight 200KG / ISOTANK.
Tris (1,3-Dichloro-2-Propyl) Phosphate (Flame Retardant TDCPP) Use:
The Product Has A High Efficiency Flame Retardant, Low Volatility, High Thermal Stability, Water Resistance, Alkali Stable And Soluble In Most Organic Substances, Processing Performance, With Plastic, Moisture, Anti-Static, Anti-Pull, Anti-Compression Performance. Widely Used In Unsaturated Polyester, Polyurethane Foam, Epoxy Resin, Phenolic Resin, Rubber, Soft Polyvinyl Chloride, Synthetic Fibers And Other Plastics And Coatings At High Temperature Pyrolysis, Can Be Used As Emulsifier And Explosion-Proof Agent.
With the augmentation of the environmental protection consciousness, the flame retardant products impact on the environment has become the development of UPR flame retardant unsaturated resin, one of the factors such as time as of flame retardant tetrabromobisphenol A cannot be break down, or recycling, environment will be long in the environment, pollution: ten bromine biphenyl ether due to produce toxic substances in the processing or the burning process, has resisted market in Europe and Japan.
Any kind of material is not omnipotent, and FRP is no exception. First FRP compared with metal difference, there are a lot of essence is isotropic materials such as metal, and FRP is anisotropic materials, metals under stress, generally fall into two elastic deformation and plastic deformation stage, the FRP under stress is generally have no obvious plastic deformation stage, no yield point, in the process of stress have statified phenomenon, can suddenly when overload fracture. Secondly, the model of FRP is lower than steel, which is 10 times lower than steel. Therefore, all products with high rigidity requirements must be carefully designed. Third, the heat-resisting far than metal material, FRP FRP so far is limited to the long-term use of temperature below 200 ℃.
2218 resin is a kind of resin of handicraft. The color of the color is yellowish brown, which has the characteristics of high gel speed and curing exothermic, high proportion of stone powder and non-stick on the surface of products. Widely used in resin figurines, Buddha, resin animal furnishing articles, resin frame, resin outdoor lamp, resin garden lamp, resin lamp, resin lamp holder, shell imitation stone, antique, imitation bronze and other special resin.
191 resin is a kind of universal resin with good mechanical strength. It is widely used in products with certain stress requirements such as pipes and canopy.
The polymer called c o o in the molecular chain is called polyester. According to the chemical structure, polyester resin can be divided into two categories. The first type is saturated polyester resin, and the carbon atoms in its molecular structure are connected by single link. No structure and molecular weight change in the process of further processing, which is thermoplastic. Polyester, polyester, polycarbonate and so on.
The second type of unsaturated polyester resin, the structure of parts are connected by a double bond between atoms and molecules in the process of further processing of the double bond can participate in chemical reactions, generally by the linear structure into insoluble soluble not melt the size of the structure of present thermosetting so.
Unsaturated polyester resin usually refers to the condensation product of unsaturated diacid (or anhydride), saturated diacid and diglycol. When its and vinyl monomer (styrene) is commonly used in a certain proportion of mixture, the organic peroxide initiator (benzoyl peroxide) can occur in the presence of copolymerization and crosslinking reaction, by the linear structure into shape structure, join the promoter tertiary amine curing reaction at room temperature.
