Preparation method of plastic support plate

Abstract

The invention relates to the field of building materials, in particular to a preparation method of a plastic support plate. The plastic support plate comprises polypropylene, polyethylene, solvent, reinforcing agent, anti-ageing agent, wood fiber, degreasing agent and plasticizing agent. The method comprises the following steps: mixing 30% of polypropylene, 30% of polyethylene, 8-10% of solvent, 3-5% of reinforcing agent and 1-2% of anti-ageing agent; mixing 15-20% of wood fiber and 5% of degreasing agent; adding 5% of plasticizing agent into the mixed raw materials, mixing, and stirring; pouring the mixture into an extruder for plasticizing; pouring the plasticized material into a plastic support plate mould; carrying out pressure forming with a hydraulic machine; and taking out the plate, and trimming. The plastic support plate produced by the method has the characteristics of high strength, light weight, water resistance, ageing resistance, worm damage prevention, no deformation, long service life and the like, is not stratified, can not be broken easily, is easy to transport, can be recycled and does not pollute the environment.

Description

technical field [0001] The invention relates to the field of building materials, and relates to a plastic pallet for production and transportation of non-fired bricks. Background technique [0002] At present, the rapid development of the unburned brick industry has also increased the demand for pallets. These pallets are mainly divided into three types, the first is PVC plastic hard board. Although it is waterproof and moisture-proof, and easy to recycle and reuse, the PVC plastic hard board adopts the production process of lamination machine, which is easy to slip when it is transferred. In summer, it is easy to deform after exposure to the sun. In winter, it is very brittle , easy to break; the second is the bamboo plywood pallet. Bamboo plywood pallets have the problem of short service life and easy delamination. Bamboo plywood is made of bamboo and a large amount of chemical adhesive pressed at high temperature, which is easy to absorb water. The layer is easy to be ...

AI Technical Summary

Problems solved by technology

Although it is waterproof and moisture-proof, and easy to recycle and reuse, the PVC plastic hard board adopts the production process of lamination machine, which is easy to slip when it is transferred. In summer, it is easy to deform after exposure to the sun. In winter, it is very brittle , easy to break; the second is bamboo splint pallet

Bamboo plywood pallets have the problem of short service life and easy delamination. Bamboo plywood is made of bamboo and a large amount of chemical adhesive pressed at high temperature, which is easy to absorb water. layer, easy to be moth-eaten, not corrosion-resistant; cement bricks are corrosive to acid and alkali, bamboo is easily corroded by these acids and alkalis, and it is not easy to recycle, and it will cause new environmental pollution after use.

The problems of wood pallets are: short service life and high cost. After repeated throwing and exposure to the sun, wooden boards are prone to cracking, deformation, insects, corrosion resistance, and recycling, causing environmental pollution.
