Flame-retardant environment-friendly foamed plastic

Abstract

The invention discloses a flame-retardant environment-friendly foamed plastic which comprises the following raw materials in parts by weight: 32-37 parts of ethylene-vinyl acetate (EVA) resin, 68-72 parts of polycaprolactone (PCL), 2.8-3.2 parts of soybean meal, 2.7-3.6 parts of wood fibers, 1.2-1.7 parts of a titanate coupling agent NDZ-TTS, 3-3.6 parts of sodium lactate, 13-17 parts of a foaming agent ADC, 8-12 parts of zinc oxide, 9-10 parts of citric acid, 11-14 parts of sodium hydrogen carbonate, 1.6-1.9 parts of diisononyl phthalate (DINP), 2.2-2.7 parts of epoxy octyl stearate, 23-28 parts of barite powder, 15-18 parts of augite powder, 7-11 parts of white carbon black, 5-9 parts of mica powder, 3-6 parts of ammonium polyphosphate, 5-8 parts of melamine sodium polyphosphate, 1.5-1.8 parts of 2,6-di-tert-butyl-4-methylphenol (BHT) and 1.3-1.6 parts of an antioxidant BLE.

Description

technical field [0001] The invention relates to the technical field of foamed plastics, in particular to a flame-retardant and environment-friendly foamed plastic. Background technique [0002] Plastic materials are widely used, such as toys, plastic bottles, packaging bags, shopping bags, etc. We cannot live without plastics. However, as we all know, ordinary PP / PE plastics are difficult to decompose in the natural environment for hundreds of years, so discarded plastic products - also known as "white garbage" - are recognized as substances that can cause great damage to the environment. The accumulation of waste plastic products mixed in the soil will affect the absorption of nutrients and water by crops, resulting in reduced crop production and affecting agricultural development. Due to its extremely difficult to decompose, landfill treatment will not only occupy a large amount of land, but the occupied land will not be restored for a long time, affecting the sustainable...

The accumulation of waste plastic products mixed in the soil will affect the absorption of nutrients and water by crops, resulting in reduced crop production and affecting agricultural development

Due to its extremely difficult to decompose, landfill treatment will not only occupy a large amount of land, but the occupied land will not be restored for a long time, which will affect the sustainable use of land; if it is disposed of by incineration, it will cause serious air pollution.
