Problems solved by technology

[0002] With the rapid advancement of the urbanization process, housing construction is in full swing in all parts of the country, and the demand for building formwork is increasing. Among them, PVC building formwork is favored by people because of its advantages of environmental protection and energy saving. However, the existing PVC building formwork Often due to poor weather resistance, it is prone to cracking or softening and deformation, which reduces the number of cycles and increases the cost of recycling, which seriously affects the promotion and use

Abstract

The invention discloses a PVC building formwork which is characterized by being prepared from, by weight, 150-200 parts of PVC recycled material, 1-4 parts of composite stabilizer, 4-9 parts of foaming regulator, 1-1.5 parts of composite foamer, 0.1-0.5 part of plasticizer, 0.3-0.9 part of inner lubricant, 0.1-0.4 part of outer lubricant and 1.5-4 parts of toughening agent, wherein the composite foamer is formed by mixing a white foamer with a yellow foamer. The invention further discloses a preparation method of the PVC building formwork. The PVC recycled material is used as a main raw material, so that waste is turned into valuable things, production cost is lower, energy resources are saved, weatherability and aging resistance of the PVC building formwork are improved, and number of circulating use times is increased and can reach higher than 35. The preparation method is simple and easy to operate, and the PVC building formwork is smooth and attractive in surface. The PVC building formwork is energy-saving, environment-friendly, low in production cost and long in service life.

Description

technical field [0001] The invention relates to a building template, in particular to a PVC building template and a preparation method thereof. Background technique [0002] With the rapid advancement of the urbanization process, housing construction is in full swing in all parts of the country, and the demand for building formwork is increasing. Among them, PVC building formwork is favored by people because of its advantages of environmental protection and energy saving. However, the existing PVC building formwork Often due to poor weather resistance, it is prone to cracking or softening and deformation, which reduces the number of cycles and increases the cost of recycling, which seriously affects the promotion and use. Contents of the invention [0003] The technical problem to be solved by the present invention is to propose a PVC building formwork with low production cost and long service life in view of the deficiencies of the prior art. [0004] The present inventi...
