Tent in the process of production is not only to use raw materials, PE, PP, PVC, etc. ) To add a large number of additives, the introduce for everybody below tent commonly used additives as well as the matters needing attention. Heat stabilizer: calcium zinc stabilizer, lead salt stabilizer is the most widely used, but the price is high, pollution of the environment, start using metal soap stabilizer in recent years, although the environmental protection, but corresponding material thermal stability is not enough. Flame retardant: traditional flame retardants for bromine flame retardants, phosphate flame retardants and inorganic flame retardants, nitrogen and phosphorus flame retardant high cost, friendly to the environment, and compatible with raw material performance is not 100%, results in the decrease of tarpaulin material. Start using expansion flame retardants in recent years, but short flame retardancy of materials, the development of the market capitalization of about flame retardant tarpaulins problem, is why flame retardant tent high prices. There are many kinds of packing. 1, modified calcium carbonate, the dispersion of the resin, connectivity, lubricity, prevent shrinkage. 2 including silane coupling agent, coupling agent and aluminum acid ester coupling agent, titanate coupling agent is generally bad connectivity. Plasticizer, since the cloud agent, plasticizer increasingly strict, the main reason leading to plastic products price rebound. Now mainly with phthalate ( For benzene) 2 formic acid ester, epoxy, citric acid ester, phosphate ester, etc. Resin compatibility is bad, easy to precipitate; Such as epoxy fatty acid methyl ester has good compatibility with PVC. Antioxidants include phenolic antioxidants, amine antioxidants and other price low phosphate ester is the most widely used, but the environmental pollution, and low molecular weight, high temperature resistance; Distribution system, improve the oxidation resistance.
