Preparation method and product of double-base wood-plastic composite material

Abstract

The invention discloses a preparation method of a double-base wood-plastic composite. The preparation method is characterized by comprising the following steps: (1), following components in parts by weight are prepared: 100 parts of wood meal, 50-80 parts of PP (propene polymer), 20-50 parts of PE (polyethylene), 2-3 parts of a titanate coupling agent, 5-8 parts of maleic anhydride grafted polypropylene, 2-5 parts of maleic anhydride grafted polyethylene, 0.3-0.5 parts of an antioxidant, 0.1-0.2 parts of a lubricant, 2-3 parts of talc and 5-6 parts of a plasticizer, wherein the mass of the wood meal is the total sum of PP and PE, and the mass ratio of PP to maleic anhydride grafted polypropylene is equal to the mass ratio of PE to maleic anhydride grafted polyethylene; (2), the wood meal is processed to obtain PP type modified wood meal and PE type modified wood meal; (3), the PP type modified wood meal, PP, maleic anhydride grafted polypropylene, the PE type modified wood meal, PE, maleic anhydride grafted polyethylene, the antioxidant, the lubricant, the talc and the plasticizer are mixed sufficiently for extrusion and granulation. The prepared PP and PE double-base wood-plastic composite has excellent combination property.

Description

technical field [0001] The invention relates to the preparation of wood-plastic materials, in particular to a preparation method and products of double-base wood-plastic composite materials. Background technique [0002] At present, wood-plastic material technology has reached a certain degree of maturity and has been widely used. In daily life, especially in the fields of home furnishing, building materials and daily necessities, such as floors, stair handrails, ventilation windows, micro-foamed cabinet boards, Surf board, etc. [0003] With the strengthening of people's awareness of environmental protection and the need to protect forest resources and reduce the use of new wood, the call for recycling low-cost waste wood and plastics has become a common concern in the industrial and scientific circles, thus promoting and promoting the development of wood-plastic materials. research and development work. But at present, the properties of wood-plastic materials are uneven ...

AI Technical Summary

Problems solved by technology

But no matter which point, its advantages and disadvantages are quite obvious, polarized

Because of this, the application range of wood-plastic materials is limited and cannot be further promoted, especially for the manufacture of some products with high performance and high strength requirements.
