Abstract

The invention discloses polyethylene eco-friendly flame-retardant foaming plastic and a preparation method thereof. The polyethylene eco-friendly flame-retardant foaming plastic comprises, by weight, 3.5-4.7 parts of high pressure low density polyethylene, 1.2-2.5 parts of ultrahigh molecular weight polyethylene, 0.8-2.3 parts of paraform, 1.2-3 parts of short cut basalt fibers, 0.8-2.5 parts of zirconium silicate powder, 2.2-3.5 parts of a fire retardant and 0.9-1.6 parts of chemical auxiliary agents. The preparation method improves polyethylene eco-friendly flame-retardant foaming plastic stretching performances, realizes excellent flame retardation effects, reduces a fire retardant use amount, and saves a production cost. The polyethylene eco-friendly flame-retardant foaming plastic is nontoxic and eco-friendly and obviously enlarges a product application scope. The preparation method substantially improves a yield of the polyethylene eco-friendly flame-retardant foaming plastic, has simple processes and a low cost, can be operated and controlled easily and is suitable for industrial production.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a polyethylene environment-friendly flame-retardant foamed plastic and a preparation method thereof. Background technique [0002] High-pressure low-density polyethylene is the lightest variety among polyethylene resins, and its crystallinity (55%-65%) and softening point (90-100°C) are low; it has good flexibility, extensibility, and transparency , cold resistance and processability; its chemical stability is good, it can resist acid, alkali and salt solution; it has good electrical insulation and air permeability, and low water absorption; it is soft, has good extensibility, electrical insulation properties, chemical stability, processability and low temperature resistance (-70°C). But the disadvantage is that it is easy to burn, which brings great safety hazards to daily life, and its mechanical strength is poor, and it is easy to age and decompose and change color ...
