Formula for producing high-heat-resistant plastic building formwork

Abstract

The invention relates to the technical field of PVC boards, in particular to a formula for producing a high-heat-resistant plastic building formwork. The formwork is prepared from, by weight, 100 parts of high-heat-resistant PVC, 1.5-3 parts of stabilizer, 0.4-1.6 parts of inner lubricant, 0.4-1.6 parts of outer lubricant, 2-8 parts of anti-impact modifier, 1-6 parts of processing modifier, 0.2-2 parts of anti-ageing agent and 5-40 parts of filler. The high-heat-resistant PVC is chloridized modified PVC or composed of chloridized modified PVC and common PVC. The defects that an existing plastic formwork is low in heat-resistant temperature, poor in weather resistance and poor in ageing resistance are overcome, the high-heat-resistant plastic building formwork produced according to the formula has the advantages of being high in heat-resistant temperature, high in weather resistance and good in ageing resistance, and building formworks used in different areas and under different weather conditions can be prepared according to client requirements.

Description

technical field [0001] The invention belongs to the technical field of building materials, in particular to a formula for producing high heat-resistant plastic building templates. Background technique [0002] In recent years, my country has newly built about 2 billion square meters of buildings every year. It is estimated that by the end of 2020, the national housing construction area will increase by 40 billion square meters. The number and speed of construction are unprecedented in the history of world construction development. In the process of building construction and use, since the building structure of our country is mainly composed of cast-in-place concrete structure. In the construction of cast-in-place concrete structures, building formwork is an indispensable and important tool. Formwork engineering generally accounts for more than 30% of the cost of concrete structure engineering, 35% of the labor volume of structural engineering, and about 55% of the construct...
