Abstract

The invention discloses a preparation method of polyethylene reinforced modified plastic particles. The polyethylene reinforced modified plastic particles are prepared from the following raw materials in parts by weight: 45-55 parts of polyethylene waste, 3-5 parts of a phthalate compound, 5-7 parts of calcium powder, 5-10 parts of mica powder, 1-2 parts of calcium stearate powder and 2-3 parts of graphite. The graphite is not easy to burn, has better flame retardance and friction resistance, can play a role in lubrication during material mixing, is light in weight, reduces the weight of a manufactured product, and is convenient to transport and use; the calcium stearate is firstly prepared into the slurry, so that the step of heating and melting the calcium stearate is omitted, the processing steps are reduced, and the working efficiency is improved; the graphite slurry is finally put into a high-speed kneading machine to be kneaded because the graphite has better lubricity, so that the graphite can be prevented from influencing the sufficient mixing of other slurry; plastic particles manufactured by mixing graphite are relatively high in flame retardance, and the mass of the product can be reduced.

Description

technical field [0001] The invention belongs to the technical field of manufacturing modified plastic particles, and in particular relates to a preparation method of polyethylene-reinforced modified plastic particles. Background technique [0002] Polyethylene, when uncolored, it is milky white, translucent, waxy, feels greasy to the touch, soft and tough, and can be slightly elongated. Generally, low-density polyethylene is softer and has better transparency, while high-density polyethylene is harder. Mainly used for mulch, handbags, water pipes, oil barrels, etc. Modified plastics refer to general-purpose plastics and engineering plastics, which are processed by filling, blending, and reinforcement to improve flame retardancy, strength, and resistance. Impact resistance, toughness and other aspects of performance. [0003] Polyethylene plastic is widely used in our daily life. As a commonly used item in life, safety and security are particularly important. As we all know,...
