Abstract
The invention provides a polyethene flame resistant material. The polyethene flame resistant material is prepared from the following components in parts by weight: 70-100 parts of polyethene, 10-15 parts of a char forming agent, 10-15 parts of sodium borate, 0.01-0.5 part of a stabilizing agent, 10-30 parts of hexabromocyclododecane, 8-12 parts of talcum powder, 4-10 parts of a solubilizer, 15-25 parts of zinc borate, 0.1-3 parts of color masterbatch, 20-40 parts of hydroxide, 1-10 parts of antimony trioxide, 15-20 parts of flame resistant polyether, 0.05-0.5 part of a coupling agent, 10-20 parts of inflatable graphite, 8-15 parts of wood powder, 5-10 parts of titanium dioxide, 5-10 parts of cane sugar, and 1-5 parts of molybdenum trioxide. According to the invention, an expansion method, a gas phase method, a physical phase method and a chemical method are combined to prepare flame resistant PE high polymer which achieves an A-class fire-proof material, the operation is simple, and the mechanical property and the fire-proof property of products are both excellent.
Description
technical field [0001] The invention belongs to the field of organic polymer materials, and in particular relates to a flame-retardant polyethylene material and a preparation method thereof. Background technique [0002] Polyethylene is a typical thermoplastic, its molecule is a long-chain linear structure or a branched structure, it is a typical crystalline polymer, and it is an odorless, tasteless, non-toxic, flammable white powder. The molded PE resins are extruded and granulated waxy pellets with a milky white appearance. Its molecular weight is in the range of 10,000 to 10,000. Those with a molecular weight of more than 100,000 are ultra-high molecular weight polyethylene fUHMWPE3. The higher the molecular weight, the better its physical and mechanical properties, and the closer it is to the required level of engineering materials. However, the higher the molecular weight, the more difficult it is to process. The melting point of polyethylene is 10-130C. It has exce...
