Special wood-plastic composite for board

Abstract

The invention discloses a special wood-plastic composite for a board, which is composed of the following components by weight percentage: 20-45% of polypropylene reclaimed material, 51-70% of straw powder of crops, 0.2-2.0% of a lubricating agent, 3-15% of a coating agent, 1.0-8.0% of a coupling agent, 1.0-5.0% of a moisture absorbent, 0.5-2.0% of an anti-aging agent and 0.1-5.5% of other auxiliaries. The special wood-plastic composite for the board provided by the invention solves the problems of composite processing and strength, can be extruded for production of high-strength boards of various specifications, the product is attractive in appearance, looks like very much to wood in appearance, has the natural smell of wood and the strength much higher than that of a common solid wood board, and can be cut and processed at will as per woodworking requirements without causing problems of deformation and the like due to water immersion, the service life is relatively and greatly prolonged, and besides, the cost is low.

Description

technical field [0001] The invention relates to a composite material, more specifically, to a special wood-plastic material for boards. The invention also relates to a method for making the special wood-plastic material for boards. Background technique [0002] With the development of social production level, people's life is more and more exquisite, and the amount of wood used in architectural decoration and furniture is increasing; at the same time, people's awareness of environmental protection and tree protection is also getting stronger; but these two This requirement seems to be a contradiction in terms. Wood-plastic materials can effectively solve the above problems. [0003] However, most of the wood-plastic materials currently on the market are made of log wood powder or wood fiber combined with plastic, which has a certain role in promoting logging and deforestation. Moreover, due to poor material strength and processability, it is limited to extrusion Simple, l...

Problems solved by technology

[0003] However, most of the wood-plastic materials currently on the market are made of log wood powder or wood fiber combined with plastic, which has a certain role in promoting logging and deforestation. Moreover, due to poor material strength and processability, it is limited to extrusion Simple, low-strength products, and high processing costs due to poor processability, have to try their best to reduce material costs, and embarked on the route of low-quality and low-price vicious circle competition. The damage to this industry is huge. of
