Problems solved by technology

[0003] However, as a packaging material, polyethylene has the disadvantage of being flammable in case of fire, and many applications require it to be flame retardant
The flame retardant system of the traditional flame retardant polyethylene material is the bromine antimony flame retardant system. However, as the problem of environmental pollution affecting human health has become the focus of global attention, the bromine antimony flame retardant system not only provides flame retardant properties but also brings The environmental hazards that come greatly limit the application of polyethylene materials, so it is particularly necessary to develop an environmentally friendly flame-retardant polyethylene material

Abstract

The invention discloses an environment-friendly flame-retardant PE material and a preparation method thereof. High density polyethylene, hydroxyethyl acrylate, triphenyl phosphite and polyvinylidene fluoride are used as main ingredients, dicumyl peroxide, maleic anhydride, sucrose acetoisobutyrate, isophorone diisocyanate, attapulgite, expanded perlite, hydrated zinc borate, vanadium diboride, aluminum titanate, bamboo charcoal powder, dithio-salicylic acid, an auxiliary agent and a silane coupler are added, processes of ball-milling, ultrasonic treatment, calcining, hot blending, foaming, curing, extruding and the like are carried out, so that the prepared environment-friendly flame-retardant PE material has excellent flame retardance, is environment-friendly, and meanwhile is high in strength, and application level of the material is increased.

Description

technical field [0001] The invention relates to the technical field of environment-friendly materials, in particular to an environment-friendly flame-retardant PE material and a preparation method thereof. Background technique [0002] PE is polyethylene, which is a thermoplastic resin obtained by polymerization of ethylene. In industry, it also includes copolymers of ethylene and a small amount of α-olefins. Polyethylene is odorless, non-toxic, feels like wax, and has excellent low temperature resistance. At the same time, polyethylene has excellent chemical stability, and is resistant to corrosion by various chemical substances such as hydrochloric acid, hydrofluoric acid, phosphoric acid, formic acid, amines, sodium hydroxide, and potassium hydroxide at room temperature. Insoluble in common solvents at room temperature, low water absorption, excellent electrical insulation. Polyethylene can be made into various application materials, especially the main material of pac...
