Straw fiber silicon plastic composite building form board and method for making same

Abstract

The invention discloses a straw fiber silicon-plastic composite building formwork and a method for preparing the same. The proportion of the formulation of per 100 kilogram of straw fiber silicon-plastic composite building formworks is as follows: 28 to 39 kilograms of plastic waste, 35 to 55 kilograms of plant straw short fibers, 15 to 25 kilograms of fly ash and 1 to 2 kilograms of auxiliary agent. The preparation method comprises the following steps of: fiber treatment of straws; mixing; high-speed fusing and extruding; mould pressing; cooling; and product package and storage. The straw fiber silicon-plastic composite building formwork and the method have the advantages of low production cost, high cost performance, good product quality, waste recycling, energy conservation and environmental protection, accordance with the development requirements of recycling economy and so on.

Description

technical field [0001] The invention relates to a building template and a preparation method thereof, in particular to a composite building template utilizing waste and a preparation method thereof. Background technique [0002] In order to speed up the development of circular economy, relevant state departments have introduced measures to encourage wood conservation and substitution work. In recent years, the construction formwork industry has begun to try to replace traditional plywood with plastic wood materials, so as to achieve the purpose of saving wood. Since the current preparation process of plastic-wood material templates mostly adopts the traditional two-step extrusion and rolling process, not only the energy consumption in the production is huge, the output and authenticity rate are low, but the impact strength and elastic modulus of the product cannot fully meet the architectural requirements. The requirements for the use of the industry, and the high requiremen...

Problems solved by technology

Since the current preparation process of plastic-wood material templates mostly adopts the traditional two-step extrusion and rolling process, not only the energy consumption in the production is huge, the output and authenticity rate are low, but the impact strength and elastic modulus of the product cannot fully meet the architectural requirements. The requirements for the use of the industry, and the high requirements for raw materials, the product is expensive, so far difficult to promote, can not give full play to the advantages of resource conservation in the wood-plastic industry
