Abstract

The invention provides a wollastonite reinforced wood-plastic building template and a preparation method thereof. The wollastonite reinforced wood-plastic building template is obtained by carrying out ball milling and stirring on the raw materials of wollastonite cebollite powder and the like in a ball mill at first, then mixing the raw materials in a mixing machine at a high speed and a low speed, and finally carrying out double-screw extrusion, mould forming, cooling shaping and traction cutting on a production line for a wood-plastic building template. The wood-plastic building template produced by the preparation method provided by the invention is wear-resistant, non-toxic and environment-friendly, capable of being cyclically used, and wide in use range.

Description

technical field [0001] The invention belongs to the technical field of building templates, and in particular relates to a wollastonite-enhanced wood-plastic building template that improves the mechanical properties of the wood-plastic building template. Background technique [0002] Building formwork is an indispensable 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 templates and other commonly used templates in the construction industry have entered people's field of vision. Compared with several types of commonly used building formwork, wood-plastic building formwork has the advantages of environmental protection and non-toxicity, high precision, fire resistance and water resistance, high repeate...
