Abstract

The invention discloses polypropylene flame-retardant plastics. The polypropylene flame-retardant plastics is prepared from the following components in parts by weight: 60 to 70 parts of polypropylene, 3 to 9 parts of glycidyl methacrylate, 4 to 10 parts of maleic anhydride, 1 to 6 parts of hexamethylphosphoramide, 10 to 19 parts of nano-calcium carbonate, 36 to 42 parts of melamine, 6 to 12 partsof azobisisobutyronitrile and 16 to 25 parts of glass fibres. In the mode, the polypropylene flame-retardant plastics provided by the invention has a good flame retardant property and has a low smokeamount in combustion.

Description

technical field [0001] The invention relates to the field of plastics, in particular to a flame-retardant polypropylene plastic. Background technique [0002] With the continuous development of science and technology and economy, daily products made of plastic play an increasingly important role in life. However, plastics are easy to burn, and the burning speed is fast, which will produce a large amount of toxic gas, causing casualties and property losses. Therefore, it is required that plastic products do not burn and have good flame retardant properties, and the smoke generation of plastics in large fires is required to be small. However, the properties of flame-retardant plastics currently used cannot meet the requirements. Contents of the invention [0003] The main technical problem to be solved by the invention is to provide a flame-retardant polypropylene plastic, which has good flame-retardant performance and produces less smoke when burned. [0004] In order to...
