Abstract

The invention discloses a composite material of waste plastics, montmorillonite and waste rubber and a preparation method thereof. In parts by weight, the raw material formula of the composite material is: 70-120 parts of waste plastics, 20-50 parts of montmorillonite, 5-15 parts of waste rubber powder, 0.1-2 parts of stearic acid, 2-5 parts of paraffin, 0.05-1 part of antioxidant tetrakis (β-(3,5-di-tert-butyl-4-hydroxyphenyl) pentaerythritol ester ; Montmorillonite has a total cationic exchange capacity of 50-200meg / 100g, particle size of 40-100 μm, and through organic intercalation treatment and dehydration deoxidation treatment. The present invention utilizes waste plastics and waste rubber, adding a small amount of montmorillonite to develop High value-added products can reduce pollution and realize the recycling of resources. The products can fully replace wooden formwork and partially replace steel formwork.

Description

technical field [0001] 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 [0002] 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. [0003] 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 polypropyl...
