Anti-aging corrosion-resistant plastic and wood composite material plate and preparation method thereof

Abstract

The invention relates to an anti-aging corrosion-resistant plastic and wood composite material plate, which is prepared from the following ingredients in percentage by weight: 5 percent to 10 percent of plant fiber, 10 percent to 15 percent of magnesium bromide, 20 percent to 25 percent of polystyrene, 3 percent to 5 percent of aluminum hydroxide, 5 percent to 10 percent of basic magnesium sulfate whiskers, 20 percent to 25 percent of wood flour, 1 percent to 2 percent of alkyl sodium sulfonate and 5 percent to 8 percent of phthalic anhydride. The invention also provides a preparation method of the anti-aging corrosion-resistant plastic and wood composite material plate. The method comprises the following steps of mixing the ingredients; performing melt blending by an extruding machine and performing granulation; performing cold pressing and shaping for preparing the anti-aging corrosion-resistant plastic and wood composite material plate. The manufacturing is convenient; the cost is low; the plastic consumption and the wood consumption are low; the environment-friendly effect is achieved; the anti-corrosion performance is realized; the service life is long. The anti-aging corrosion-resistant plastic and wood composite material plate can be widely applied to various fields. The anti-aging corrosion-resistant plastic and wood composite material plate prepared by the method has the anti-aging and anti-corrosion performance; the preparation method is simple; the raw materials can be easily obtained.

Description

technical field [0001] The invention relates to the technical field of wood production, in particular to an anti-aging and corrosion-resistant plastic-wood composite material board and a preparation method thereof. Background technique [0002] Wood-plastic composite materials are made of resins such as polypropylene or recycled waste plastics and natural biological fibers such as wood powder and straw powder. They have dual characteristics of wood and plastic, and fully embody a series of advanced concepts such as resource utilization and environmental protection. , is an ideal green product. It has a wide range of applications, and also solves the problem of recycling waste resources in the plastic and wood industries. But even so, in the early stage of the development of wood-plastic composite materials, the content of plant fibers was low, and the plastic polymer base material was the main component, which improved the anti-mold and anti-corrosion ability of wood-plasti...

Problems solved by technology

However, with the improvement of technology in the later period, the proportion of plant fiber increased. Since plant fiber contains half sugar and even nutrients such as starch and protein, wood-plastic composite materials are more susceptible to decay.
