Inorganic flame retardant for thermosetting resin

Inorganic flame retardant for thermosetting resin

Inorganic flame retardant is widely used because of its low price and thermal stability, non - volatilization, non - precipitation, non - toxic, non - corrosive toxic gas.

Currently, the inorganic flame retardant of thermosetting resins is widely used, including aluminum hydroxide, antimony trioxide, magnesium hydroxide, boron and red phosphorus.

Aluminum hydroxide is the main variety of inorganic flame retardants for thermosetting resins, 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 of the inorganic flame retardants 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 inorganic flame retardant of thermosetting resin is white crystal, density 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.



Trixylyl Phosphate(TXP) Use

Phosphate Trisphenylene Phosphate Is Low, Resistant To Hydrolysis, Good Flame Retardant Can Be Used As Vinyl Resin, Cellulose Resin, Natural And Synthetic Rubber Plasticizer, Low Volatility, Good Water Resistance, Flame Retardant. Trichenylene Phosphate Use For Use In Combustible Turbine Oils, With Good Flame Resistance And Good Thermal Oxidation Safety, Good Lubricity, Extreme Pressure Antiwear Additives For Lubricants, Thickeners. Also Used For Fire-Resistant Turbine Oil, With Good Thermal Oxidation Stability, Lubricity, As A Lubricant Anti-Wear Additives, Plasticizers, But Also For Flame Retardant, Wear-Resistant, Resistant To The Mold Of The Cable, Ethylene Conveyor Belt, Artificial Leather, Foam, Flooring Materials, But Also In Metallurgy, Electricity, Mechanical Engineering And Other Aspects As A Fire-Resistant Hydraulic Oil.


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%.

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.
