Abstract

The invention discloses wood-plastic type engineering plastic composition. The composition comprises components in parts by weight as follows: 100-110 parts of polyvinyl chloride, 50-60 parts of wood flour, 3-5 parts of an acrylate type macromolecular copolymer ACR-401, 6-9 parts of a plasticizer, 1-3 parts of an anti-ageing aid and 5-7 parts of titanium dioxide. Through the scheme, the wood-plastic type engineering plastic composition is long in service life, properties are not changed after long-term use, replacement is not required, the cost can be reduced, and the composition has the very good elasticity modulus and very good physical and mechanical properties such as compression resistance, bending resistance and the like.

Description

technical field [0001] The invention relates to the field of modified plastics, in particular to a wood-plastic engineering plastic composition. Background technique [0002] Wood-plastic, that is, wood-plastic composite material, is a new type of composite material that has been booming at home and abroad in recent years. It refers to the use of polyethylene, polypropylene and polyvinyl chloride, etc. Powder, rice husk, straw and other waste plant fibers are mixed into new wood materials, and then processed by extrusion, molding, injection molding and other plastic processing techniques to produce plates or profiles, which are mainly used in building materials, furniture, logistics packaging and other industries. Existing wood-plastic composite materials have poor elastic modulus and poor durability. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a wood-plastic engineering plastic composition, which can be us...
