Problems solved by technology

[0005] At present, most of the wood-plastic materials on the Chinese market are made of log wood powder or wood fiber and plastic, which has a certain role in promoting logging and deforestation. Moreover, due to the poor strength and processability of the material, it is limited to extruding some relatively simple materials. , Low-strength products, and high processing costs due to poor processability, so we have to try our best to reduce material costs, and embarked on the route of low-quality and low-price vicious circle competition, which will cause huge damage to this industry.

Abstract

The invention discloses a plastic grid type micro-foamed sheet. The raw materials applied to the plastic grid type micro-foamed sheet is waste mineral slag after production in a local phosphate fertilizer plant and local crops straw; the building decorative wooden plastic material with energy-saving, environment-friendly, low price and high quality can be prepared by a few amount of high polymer materials and additive, thus the material cost is reduced and the market is won; meanwhile, the sheet also solves the environmental pollution of local straw incineration and phosphorus mineral slag piling, pushes the employment of labor force, finds out substitutes for woods, and creates property for the society.

Description

technical field [0001] The invention relates to a wood-plastic material and a processing method thereof, in particular to a micro-foamed plate in a plastic sheath format and a preparation method and application thereof. Background technique [0002] Thermoplastic wood-plastic composite (WPC) is a modified thermoplastic material that is filled and reinforced with wood fiber or plant fiber, and made by different processing methods such as hot-compression compounding and melt extrusion. [0003] Most of the thermoplastic wood-plastic composite materials currently on the market are made of metal or wood, the cost is high, and a large amount of mineral resources are used or forests are destroyed, and more resources are consumed. Sometimes the product life is not long and it is very easy to damage. [0004] In some foreign countries, wood-plastic products whose wood powder accounts for more than 50% of the total proportion can be regarded as wood products and sold to the society; ...
