PVC plastic door development needs to consider both flame retardant and smoke suppression
The development direction of PVC plastic door in China must be in flame retardant system, and both flame retardant and smoke elimination are considered. At present, there are few products of low-smoke and incombustible grade in PVC plastic building materials in China. However, there have been some recent advances in PVC plastic doors. The sichuan fire science research institute USES a variety of metal oxides, supplemented with PVC resin modifiers, and at a certain temperature, stirring at a high speed, so as to mix it together and make an SSH-93N flame retardant. The flame retardant smoke agent has good flame retardancy and smoke suppression effect on PVC resin, which can make it a low-smoke, low-toxicity, high fireproof refractory product.
The chemical department of shantou university adopts Sb203, CaCO3 and metal oxide to make flame retardant smoke system, which can be used for PVC resin to make high flame retardant and low-smoke PVC plastic.
Beijing institute of technology to study the two smoke suppression agent for PVC - molybdenum compounds and magnesium - zinc compounds, add 2-5 copies of quality plastic, can reduce quantity of smoke a 30% 30%, is the very effective smoke suppression of the flame retardant PVC.
Institute of zhengzhou light industry with Al3, and a variety of coordination compound with inorganic flame retardants, made from the inorganic compound flame retardants, it has the added quantity is little, good flame retardancy, low smoke, non-toxic, low price, etc. The basic formula of compound flame retardants for the main body is PVC100, pb stabilizer 4.0, lubricant 0.4, other auxiliaries 3.5 to 5.0.
Huizhou university by analyzing the different decomposition reaction of metal ion as a catalyst to PVC and smog formation, the influence of the coordination effect of the positive and negative ions, the preparation of hard, mass PVC materials by flame retardant smoke suppression processing FR - X flame retardant smoke elimination agent, made of the flame retardant smoke elimination agent flame retardant low smoke hard PVC Windows and doors profiles has excellent flame retardant performance.
