Problems solved by technology
Although some of the above formulas have improved the mechanical properties of wood-plastic building templates to a certain extent, they have led to a significant increase in material costs. Although some have used cheap raw materials, the number of times the templates have been used has not been significantly improved, which greatly limits the use of wood-plastic building templates. promotion of templates

Abstract
The invention provides an enhanced wood-plastic building board proportioning method. The method has the beneficial effects that surface treatment is carried out on wollastonite by adopting phosphogypsum and carbide slag to increase the surface area of wollastonite; wollastonite has good compatibility through surface modification with a silane coupling agent; wollastonite can be added to polyvinyl chloride wood-plastic materials in a large proportion as an inorganic filler; multiple mechanical properties of building templates can be improved through the excellent reinforcing properties of wollastonite powder fibers, so that the templates can be reused more than 30 times under the condition of normal use; compared with common activated light calcium carbonate inorganic fillers, the raw materials, namely the wollastonite powder fibers, have the effects of effectively reducing the costs of the raw materials while improving the properties of the templates and providing a new comprehensive utilization way for industrial solid wastes including phosphogypsum and carbide slag when being added to the formula to produce the wood-plastic building templates.
Description
technical field [0001] The invention belongs to the technical field of wood-plastic composite building formwork. Specifically, the invention relates to a raw material ratio of wollastonite reinforced wood-plastic building formwork. Background technique [0002] Building formwork is an essential consumable raw material for daily production in the construction industry. In recent years, with the depletion of natural resources and the enhancement of people's awareness of environmental protection, wood-plastic composite (WPC) building formwork is gradually replacing steel formwork, wood plywood formwork, bamboo plywood formwork and other common formwork in the construction industry into people's vision. Compared with common formwork, wood-plastic building formwork has the advantages of environmental protection and non-toxicity, high precision, fire resistance and water resistance, high reuse times, and the use of agricultural waste for production, but it also has the disadvanta...
