Abstract

The invention discloses a PVC (Polyvinyl Chloride) building template, which comprises the following raw materials in parts by weight: 22 to 35 parts of chlorinated polyethylene, 12 to 18 parts of filler, 0.1 to 0.3 part of aluminum titanate coupling agent, 50 to 80 parts of polyvinyl chloride, 20 to 30 parts of straw fiber powder, 1 to 3 parts of aluminium hydroxide, 0.8 to 1.8 parts of zinc borate, 1 to 3 parts of stabilizer, 0.5 to 1 part of ultraviolet screening agent, 0.5 to 1 part of antioxidant, and 0.5 to 1 part of antibacterial agent. Compared with an existing PVC building template in the market, the PVC building template provided by the invention has higher hardness and elasticity modulus, good shock strength, heat resistance, weather fastness and acid and alkali corrosion resistance and favorable stability, is free of deformation and warping, light in self-weight and convenient to construct, has favorable secondary fabricability, high repeating utilization ratio and long service life, and is worth popularizing since a product can be recycled and reused.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a PVC building template and a preparation method thereof. Background technique [0002] The building formwork is a temporary support structure, which is manufactured according to the design requirements, so that the concrete structure and components are formed according to the specified position and geometric size, maintain their correct position, and bear the self-weight of the building formwork and the external load acting on it. The purpose of formwork engineering is to ensure the quality of concrete engineering and construction safety, speed up the construction progress and reduce engineering costs. At present, the types of building formwork used in my country's construction industry mainly include wooden building formwork, tempered building formwork, building wood plywood, steel and bamboo building formwork, plastic building formwork, etc. Among them, plastic bui...
