Expansive flame retardant application
The expansion type flame retardant was first noticed in the flame retardant coating. Now expansive flame retardant is used in plastics, textile, coating, leather protein and other fields.
Expansive flame retardant application (1) plastic. Most plastics are combustible, and it is precisely because the carbon layer produced by the combustion of the nitrogen and phosphorus expansion flame can effectively prevent the generation of polymer droplets, it is suitable for the flame retardant of polyolefins. The research of expansive flame retardant is mainly aimed at PP, EVA, ABS, epoxy resin. At present, the expansion type flame retardant is applied to plastic mainly for poor compatibility, easy moisture absorption and poor mechanical properties of materials.
The yukon xiang synthetic Trimer tie, the highly symmetric structure, thermal stability, high nitrogen and phosphorus than the existing expansion type flame retardant is 50 ~ 100 ℃ higher decomposition temperature, can satisfy the requirement of almost all engineering plastics processing, and Trimer insoluble in water and most organic solvents, there is no common IER hygroscopicity.
Expansive flame retardant application (2) textile. Almost all of the textile fiber is organic polymer, and the vast majority of decomposition occurs at 300 ℃, burning with the release of combustible gas and volatile liquid precipitation. According to incomplete statistics, textile fire accounts for more than half of fire accidents and high mortality rate, so textile flame retardant is highly regarded. It is mainly aimed at the flame retardant of polyester, nylon and other synthetic fibers.
Nylon 66 has been used for many years in both military and civilian use, but its droplet problem has not been solved well. LinyaoLi [10], such as the expansion type flame retardant - contains ammonium polyphosphate, melamine and pentaerythritol, applied to the nylon 66, the LOI and vertical burning test results show that the nitrogen and phosphorus expansion type flame retardant can effectively prevent the molten drops down, by TGA, DSC, SEM experiment proves, after processing of nylon 66 can promote the formation of the coking residual quantity, the coking residual quantity can influence the properties of nylon 66 drop proof, but lower tensile properties.
Cresyl Diphenyl Phosphate(CDP) Use
This Product Is Flame Retardant Plasticizer, And Resin Compatibility, For Polyvinyl Acetal, Nitrocellulose, Polyvinyl Chloride, Natural Rubber And Synthetic Rubber; Can Also Be Used For Synthetic Lubricants And Hydraulic Oil; Substitutes For Triphenyl Phosphate. Applicable To Polyvinyl Chloride, Vinyl Chloride Copolymer, Polyvinyl Acetal, Nitrocellulose, Ethyl Cellulose, Cellulose Acetate Butyrate And So On.
Since cellulose fiber itself is a polyol polymer that ACTS as a carbon source, the addition of an expansive flame retardant to cellulose fibers usually has good flame-retardant effects. For natural material cotton, crosslinking agent is often used more fixed, hydroxy melamine use expansion type flame retardant, only generates heat coking protective layer, and react with fiber generates the temperature as high as 500 ℃ still have good performance of oxygen isolation of carbonized structure.
Expansive flame retardant application (3) leather. As by collagen (contain a large amount of carboxyl and amino) made of leather, due to their high hydrophilicity, and in the course of processing, the vast majority in the water, so the expansion type flame retardant has been sulfating, sulfonic acid such as water treatment, and can combine with leather. More often used in leather expansion type flame retardant is single-component model, expansion type flame retardant used in leather, can solve using textile, plastic, paint and other industries caused by traditional flame retardant leather hand feeling, plump, sensory performance defects such as softness, because of melamine itself is a good filling agent of leather, so after bulk expansion type flame retardant processing leather, won't make the mechanical properties of leather.
Quan-jie wang, etc. Use of pentaerythritol, phosphoric acid, melamine cage phosphate was synthesized, with formaldehyde and sodium bisulfite modification, found that the flame retardant have good expansion ratio, thermal stability and residual carbon ratio of leather after flame retardant treatment, its physical performance, the oxygen index increased, and the flameless time is short.
Expansive flame retardant application (4) paint. The expansion type flame retardant coating is mainly used as internal wall material due to poor weatherability. The present - resistant exterior wall coating is used for industrial structures with serious fire hazards. And the main problem of this kind of paint is hydrophilic. The study shows that the chemical stability of the expansive flame retardant coatings based on the APP is less than ideal, and the radiation and humidity of the sun can reduce the stability. In addition, the expansive flame retardant coating that has been stable for a long time at high temperature is very high in the coating of metal surface, which is the direction of future development.
