Thermosetting resin flame retardant
Inorganic flame retardant is widely used because of its low price and thermal stability, non - volatilization, non - precipitation, non - toxic, non - corrosive toxic gas.
The commonly used thermosetting resin flame retardants are aluminum hydroxide, antimony trioxide, magnesium hydroxide, boron and red phosphorus.
Aluminum hydroxide is the main flame retardant of thermosetting resin, accounting for more than 80% of the total amount. Features: low price, not only flame retardant but also reduce the amount of smoke. Suitable for unsaturated polyester resin, vinyl ester resin, epoxy resin.
Thermosetting resin flame retardant antimony trioxide used alone flame retardant effect is not big, but when it is used with containing halogen flame retardants will produce strong flame retardant effect, is an effective flame retardant. Suitable for unsaturated polyester resin, vinyl ester resin, epoxy resin.
The thermosetting resin flame retardant magnesium hydroxide is a white crystal with a density of 2.36, which has the effect of flame retardant and smoke elimination.
Red phosphorus, unlike white phosphorus, is stable in the air. It can be used as an inhibitor of epoxy resin and other resin. Red phosphor melting point is high, the addition quantity is small, the physical property of phosphor flame retardant polymer is good.
Nano low hydrated zinc borate after add in plastic, the tensile strength of the composites can be improved, increased the composite with notch or without notch impact strength, and increase its ability to resist uv and less prone to aging. Nano low hydrated zinc borate has better flame retardant, sterilization, rust, widely used in modified plastic lining door, handle, prevent mould seal, high strength composite materials, can make the refrigerator food antimicrobial preservation, has greatly prolong food storage time.
Also can be used as a food supermarket shelves, food baskets, food boxes, counter, mesa, cart, elevators, bus bar, sit chair, desk, toilet and bathroom wall, packaging materials, furniture, building paint, etc.
Magnesium hydroxide is a good fireproof material and can also help to improve the resistance of synthetic materials. It also provides water vapor as a kind of anti-smoking agent. Magnesium hydroxide is recognized as an excellent flame retardant for flame retardant, smoke suppression and filling of triple functions in the rubber industry. Widely used in rubber, chemical, building materials, plastics and electronics, unsaturated polyester and paint, paint and other polymer materials.
Especially for mine air duct Shanghai juji cloth, PVC whole core conveyor belt, flame retardant aluminous model board, tarpaulin, PVC wire and cable, mine cable sheath, cable accessories smoke flame retardant, antistatic, but instead of aluminium hydroxide, it has excellent flame retardant effect. Magnesium hydroxide has better anti-smoking effect than similar inorganic flame retardant. Magnesium hydroxide is free of harmful substances in the process of production, use and waste, and also neutralizes the acidic and corrosive gases produced during combustion. When used alone, the dosage is generally 40% ~ 60%.
Tris (1,3-Dichloro-2-Propyl) Phosphate (Flame Retardant TDCPP)
CAS No.:13674-87-8
HS: 29199000
Tax Rate (%): 9%
Tris (1,3-Dichloro-2-Propyl) Phosphate (TDCPP) Raw Materials: Phosphorus Oxychloride, Epichlorohydrin
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.
Magnesium hydroxide is an inorganic flame retardant filler of high polymer matrix composite. As with aluminium hydroxide, magnesium hydroxide flame retardant is rely on chemical decomposition heat absorption and release water when heated and flame retardant effect, so it is non-toxic, low smoke and chemical stability of magnesium oxide generated after decomposition, do not produce secondary pollution, etc. However, compared with halogen-containing organic flame retardants, it is more than 50% of the total amount of flame retardant.
Because magnesium hydroxide as the inorganic matter, poor surface and the compatibility of polymer binders, such a high filling amount, if does not carry on the surface modification, filling into the high polymer material, will be to lower the mechanical properties of composite materials. Therefore, must be surface modification treatment, to improve its compatibility with polymer binders, make the mechanics properties of filler material is not falling, even part of the material mechanical properties improved.
Experiments show that without modification of the magnesium hydroxide exists in the form of aggregate in PP, although very fine powder itself, but as a result of particle surface is incompatible with the PP matrix, particles aggregate and PP matrix is a clear line between even empty.
The cavitation of magnesium hydroxide particles after escaping due to brittle fracture shows that the unmodified magnesium hydroxide is only a filling flame retardant effect in PP, and does not bond with PP. The surface modified magnesium hydroxide is dispersed uniformly in PP matrix, and the particles are scattered in the materials in the form of primary particles or small agglomerates.
The study of flame retardant in China started late, although the development has been achieved, but compared with the advanced countries, there is still a certain gap in the yield and variety structure. At present, the development of domestic research and development focuses on inorganic flame retardants, red phosphorus microencapsulation, expansive flame retardant and other fields, and has achieved certain results. No halogen, high efficiency, low smoke, and low - toxic flame retardant is the development direction of flame retardant.
