Abstract

The invention discloses a waste plastic, montmorillonoid and waste rubber composite and a preparation method thereof. According to a formula, the composite is prepared from the following raw materials in part by weight: waste plastic 70-120, montmorillonoid 20-50, waste rubber powder 5-15, stearic acid 0.1-2, paraffin wax 2-5, antioxidant(beta-(3,5-di-tert-butyl-4-hydroxyphenyl)- pentaerythritol ester 0.05-1, wherein the montmorillonoid subjected to organic intercalation, dehydration and deoxidation has a cation exchange total capacity of 50 to 200meg / 100g and a particle size of 40 to 100mum. In the invention, the waste plastic and rubber are added with a small amount of total montmorillonoid to develop a product with a high added value, so the pollution is reduced, resource recycling is realized and the product can replace all wooden templates and some steel templates.

Description

technical field The invention relates to a composite material, in particular to a waste plastic, montmorillonite and waste rubber composite material and a preparation method thereof. Background technique Nowadays, waste rubber and waste plastics are wastes that seriously pollute the environment. A large number of these wastes are used to develop high value-added products, so as to reduce pollution, turn waste into regeneration, and regenerate resources. This is a resource with economic and environmental benefits. Reuse engineering. The composite material of the invention uses waste plastics, montmorillonite and waste rubber as main raw materials, and is prepared to fully replace wooden templates and partially replace steel templates. Chinese invention patent "200410011364.6" discloses the invention of "preparation of building formwork from wood materials, waste plastics and fly ash". This patent uses sawdust, waste plastic polyethylene or polypropylene, and fly ash. The u...
