Abstract

The invention discloses a high-strength wood-plastic composite material and a preparation method thereof. The high-strength wood-plastic composite material is prepared from the following raw materials in parts by mass: 50 to 60 parts of polyethylene, 25 to 30 parts of plant material, 8 to 10 parts of reinforcing agent, 2 to 3 parts of coupling agent and 2 to 3 parts of lubricating agent, wherein the reinforcing agent is a mixture of lignin and sepiolite in a mass ratio of 1 to (1.5 to 2). In the high-strength wood-plastic composite material, the mixture of the lignin and the sepiolite is added as a reinforcing agent, so that the comprehensive mechanical performance of the wood-plastic composite material is improved; meanwhile, the temperature toleration of the wood-plastic composite material is improved at a certain degree.

Description

technical field [0001] The invention relates to the field of wood-plastic materials, more specifically, to a high-strength wood-plastic composite material and a preparation method thereof. Background technique [0002] Wood-plastic composite board is a kind of wood (wood cellulose, plant cellulose) as the basic material, thermoplastic polymer material (plastic) and processing aids, etc., which are mixed evenly and then heated and extruded by mold equipment. The high-tech green environmental protection new decorative material has both the performance and characteristics of wood and plastic, and is a new composite material that can replace wood and plastic. As a new composite material, wood-plastic composite material has the advantages of long service life, strong plasticity, environmental protection and health. However, the current wood-plastic composite material generally has the problem of unsatisfactory mechanical properties. Therefore, it is necessary to provide a high-st...
