AI Technical Summary

Problems solved by technology

However, since the building formwork is mostly steel formwork and bamboo wood formwork, it needs to consume a lot of ore, coal, electricity, forest and other resources every year, which has caused great harm to environmental protection.
In recent years, my country's plastic formwork has developed very rapidly, but its strength is worse than traditional steel formwork and bamboo wood formwork, and its popularization and application are greatly restricted.

Abstract

The invention discloses a high-strength building template which is prepared from the following raw materials in parts by weight: 60-90 parts of PVC (polyvinyl chloride) resin powder, 3-4 parts of a stabilizing agent, 8-12 parts of wood flour, 7-8 parts of a processing aid, 0.8-1.5 parts of a foaming agent, 1.5-2.5 parts of a plasticizer, 0.3-0.5 part of a lubricant and 0.5-0.6 part of a coupling agent, wherein the lubricant comprises an internal lubricant and an external lubricant at a mass ratio of 1:1.5. The prepared building template has the characteristics of high strength, good toughnessand strong impact resistance.

Description

technical field [0001] The invention relates to the technical field of building formwork, in particular to a high-strength building formwork. Background technique [0002] Building formwork is an important tool in the construction of concrete structures. The quality of the formwork directly affects the quality, cost and benefit of the construction of the project. The development of formwork technology is an important part of the progress of construction technology. In recent years, my country's real estate industry has developed rapidly, and the formwork industry has also developed rapidly. However, since the building formwork is mostly steel formwork and bamboo wood formwork, it needs to consume a lot of ore, coal, electricity, forest and other resources every year, which has caused great harm to environmental protection. In recent years, my country's plastic formwork has developed very rapidly, but its strength is worse than traditional steel formwork and bamboo wood form...
