Resin type flame retardant
The third generation of wood flame retardants, which are at the leading level in China, has been developed and applied to industrialization. At present, many artificial board production enterprises have begun to use the third generation of wood flame retardant technology to produce flame retardant type man-made board.
The third generation of wood fire retardant is refers to the flame retardant resin type, is respectively according to the requirements of different flame retardant urea-formaldehyde resin, phenolic resin and melamine and inorganic flame retardants such as diammonium phosphate and ammonium polyphosphate compound and into. With the first generation of inorganic flame retardants, the second generation of inorganic and organic flame retardant simple mechanical mixing compared to get flame retardant, the third generation of the resin type flame retardant effect on physical and mechanical properties of wood, low hygroscopicity, flame retardant nor precipitate.
The specific treatment is to put the wood in a high pressure tank, then vacuum it, then pressure the flame retardants into the wood. Wood is flame retardant after impregnation, in the process of drying resin curing, on loss of inorganic flame retardants formula is easy produce coated fixation effect, so as to improve the flame retardant of resistance to erosion, migration and hygroscopicity. Wood flame retardants will be further developed in the future of ultrafine, nano-chemical, organic-inorganic compound, low-toxicity and smokeless.
It is understood that in 2008, the total production of China's man-made board was 9409 million cubic meters, which has become the first major country of artificial board production and furniture export. With the rapid development of the real estate industry and the increasing of public places, more than 90% of timber products are used for interior decoration and furniture manufacturing.
Because wood is one of the main ignition of the fire, according to the mandatory national standard GB20286-2006 the "public places with the combustion performance and flame retardant products identification, the provisions of the public use of wood products must comply with the relevant standard of flame retardant grade, so the wood fire-retardant technology has been closely watched. At present, the proportion of flame retardant wood products in China is far less than 10%, while the developed countries account for 15% ~ 20%, and the development potential of wood flame retardants in China is huge.
Wood is a porous complex natural organic matter mainly composed of cellulose, hemicellulose and lignin. It is characterized by the insoluble and non-melting of the normal processing and usage conditions, so the processing method is different from the synthetic polymer; The wood molecules contain a large number of hydroxyl and hydroxymethyl groups, so they have strong moisture absorption and poor dimensional stability. In addition to flammable, there are also fragile and volatile chemical degradable characteristics. The above characteristics of wood determine that the mainstream varieties of wood flame retardants are water-solvent products, and the leading additive method is the infusion method.
Triphenyl Phosphate (TPP)
Triphenyl Phosphatetpp-cas: 15-86-6
EINECS number: 204-112-2
Chinese Name: Triphenyl Phosphate
Chinese alias: phosphoric acid three phenyl ester; flame retardant TPP; TPP
English Name: Triphenyl Phosphate
English alias: Triphenyl Phosphate free of phenol; Triphenyl Phosphate (TPPa); Triphenyl Phosphate white XTL Phosphoric acid triphenyl ester; TPP
Molecular formula: C18H15O4P; OP (OC6H5) 3

Flame retardant TPP has many advantages, such as excellent transparency, softness, bacterial resistance, and water proof, grease-proof, good electric insulation, as well as good compatibility. Flame retardant TPP is mainly used as the flame-retardant plasticizer for cellulose resin, vinyl resin, natural rubber and synthetic rubber. And it may also be used as the flame-retardant plasticizer for glyceryl triacetate thin ester and film, rigid polyurethane foam, phenolic aldehyde resin, and PPO, etc.
Flame retardant TPP is a kind of halogen-free environment-friendly flame retardant with phosphorus element. Most of the products in the market are self-colored flaky crystal, our product is self-colored crystalline powder, and is more soluble in organic solvents. TPP is not soluble in water, but soluble in benzene, chloroform, ether and acetone, and slightly soluble in Z alcohol. Flame retardant TPP is nonflammable with slight aromatic odor and slight deliquescence. The fusion point is about 50 ℃, and fast melts to hoop-shape when heated. The lubricate effect is excellent, and it is often used as the flame retardant plasticize lubricant. What is more, it is used as the flame retardant for many plastics and resins, such as phenolic aldehyde resin, epoxy resin and so on.
Characteristics of wood flame retardant
1: the flame retardant effect is high, which can prevent the flame burning, and can suppress the smouldering (no flame combustion, red hot burning);
2: the flame retardants themselves are not toxic, and in the process of production and use, they should not pollute the environment. The pyrolysis products of flame retardant wood should be less smoke, less toxic, less irritating and less corrosive.
3: the flame retardant property is durable, and the heat and light decomposition is not occurred during the process of use, and it is not easy to hydrolyze and lose.
4: low moisture absorption, good dimensional stability of flame retardant wood;
5. The physical and mechanical properties and process performance of wood are not affected.
6. Anti-rot and moth proofing performance;
7: the visual, tactile and regulatory environment of wood is largely unaffected;
8: low cost, abundant source, easy to use.
1) in view of the development of science and technology, in a long period of time, phosphorus - nitrogen - boron is a water-based fire retardant system will still be the mainstream of wood fire retardant, future work is mainly to further improve the erosion resistance, resistance transference and reduce the cost.
2) with the progress of the society, people not only requirement for the performance of the material is higher and higher, and more and more comprehensive, flame retardant, corrosion resistance, insect-resistant, erosion resistance and size stability effect of wood protection agent will become the main direction of wood fire retardant.
(3) when the fire broke out, the direct casualties caused by smoke, especially toxic smoke and indirect property loss caused by obstruction of fighting often as the loss of fire, smoke suppression sex research will become an important topic of the wood fire retardant.
