Flame-retardant PE plastic

Abstract

The invention discloses a flame-retardant PE plastic. The flame-retardant PE plastic comprises the following components in parts by weight: 130-135 parts of PE, 10-15 parts of calcium carbonate, 10-20 parts of tribasic lead sulfate, 7-9 parts of phthalate anhydride, 6-9 parts of acrylonitrile, 10-14 parts of alkyl benzene sulfonate, 5-9 parts of dimethyl siloxane, 10-13 parts of ferrocene, 10-15 parts of nano silicon dioxide, 10-15 parts of glass fiber, 10-12 parts of sodium antimonate, 10-15 parts of ammonium polyphosphate and 20-30 parts of triphenyl phosphate. The flame-retardant PE plastic has a good flame-retardant function; an obvious flame-retardant function can be performed when a very small amount of flame-retardant PC plastic is used. The flame-retardant PE plastic does not affect the mechanical strength of a plastic product and particularly does not lower the thermal deformation temperature, the mechanical temperature and the electric insulation property of the plastic product. Meanwhile, the compatibility between the flame-retardant PE plastic and resins is high; the flame-retardant PE plastic does not migrate in the plastic product, and can not be separated out or extracted from the plastic product.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a PE flame-retardant plastic. technical background [0002] With the continuous development of science and technology and economy, daily necessities made of plastics play an increasingly important role in daily life. However, plastics are easy to burn, and the burning speed is fast, and a large amount of toxic gases will be produced. With the wide application of plastics in construction, furniture, transportation, aviation, aerospace, electrical appliances, etc., at the same time, there are countless fires caused by plastic products. The fire situation is not optimistic. Some major fire accidents occur frequently, and many of them are nylon mesh, Flammable materials such as polyurethane foam burn rapidly, causing death, injury and property damage. The vast majority of plastics are flammable substances, but in plastic construction materials, transportation materials,...

Problems solved by technology

Mechanisms such as: protective film mechanism, otherwise gas mechanism, cooling mechanism, and termination chain reaction mechanism are given in existing textbooks. These can provide a vague direction for the selection of flame retardants, but they cannot provide real effective information. s help
