The flame-retardant reinforced modified PE composite material provided by the invention is simple in preparation process and convenient in use, and can be used for realizing the industrial automatic production.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a flame-retardant reinforced modified PE composite material and a preparation method thereof. Background technique [0002] Polyethylene (PE) is cheap, easy to form and process, and has many excellent properties, so it has a large demand and a wide range of applications. However, the impact strength of PE alone is not good, and it is easy to burn, thus limiting its application range. Contents of the invention [0003] The object of the present invention is to provide a high flame-retardant, high-strength, low-cost flame-retardant reinforced modified PE composite material and a preparation method thereof. [0004] The technical solution adopted by the present invention to solve the technical problem is: a flame-retardant reinforced modified PE composite material, the components of which are proportioned by mass percentage: PE 30%-60%, flame retardant 20%-30%, 10%-40%...
