Foamed HDPE plastic sheet

Abstract

The invention relates to a foamed HDPE plastic sheet. The foamed HDPE plastic sheet comprises the following components in percentage by mass (%):70-80% of HDPE, 3-5% of PE foaming agent, 5-7% of white oil, 8-11% of ultraviolet absorber and 4-7% of antioxidant. A method for manufacturing the foamed HDPE plastic sheet comprises the following steps of stirring, drying and melting, carrying out mold stripping, setting and carrying out annealing treatment. The molded sheet has wide application range and has the advantages of ultraviolet resistance, no rot, no deformation, no color fading, insect pest repellence, wear resistance, water tightness, no cracks, no need of maintenance and the like. The preparation method of the foamed HDPE plastic sheet is simple in operation process and both time and labor are saved; and the prepared finished product has the advantages of relatively long service life and better application effects.

Description

technical field [0001] The invention relates to a plastic sheet, in particular to a foamed plastic sheet using HDPE (high-density polyethylene) as a raw material and a preparation method thereof. Background technique [0002] With the improvement of people's quality of life, various leisure equipments appear on a large scale in many places such as parks, communities, and schools. Among these leisure facilities, chairs are the most, and many places are set up in the walkways or rest areas for people to rest. [0003] Traditional chairs are made of wood-plastic composite materials, that is, the raw materials used are a combination of wood powder and plastic materials such as PE, and the boards used in these chairs are made with a certain ratio. But these chairs have to withstand the wind and rain all year round. Because of the wood powder, the boards are particularly easy to rot, and they are also vulnerable to insect pests in the garden; Severely discolored, deformed or bro...

AI Technical Summary

Problems solved by technology

But these chairs have to withstand the wind and rain all year round. Because of the wood powder, the boards are particularly easy to rot, and they are also vulnerable to insect pests in the garden; Cause severe discoloration, deformation or breakage of the board

These chairs have a short lifespan

Therefore, all-plastic panels will be used to replace the original wood-plastic composite panels, but if the raw materials are not selected well or the production process is improper, many defects will occur, such as embrittlement of plastic panels or wear resistance. characteristics, so the chairs made of these inferior all-plastic panels cannot achieve the desired effect, and it will cost a lot of money to make new chairs to replace these damaged chairs
