Problems solved by technology

However, in the process of storage and use, affected by many factors, the skin will still peel and fall off, which not only seriously affects the number of turnover times and project quality of building formwork, but also causes huge consumption and waste of wood resources.
However, there is no report on the use of copy paper in the production of building templates.

Abstract

The invention discloses application of copy paper in manufacturing of a building template, and belongs to the technical field of copy paper application. It is found through a large number of experimental studies that the copy paper can be used in manufacturing of the building template and can be integrated with a core layer and surface glue, so that an intangible, smooth and uniform protective layer is formed on the surface of the building template, a building template finished product does not peel off or fall off surface, and the number of times of normal use and turnover reaches 20-30; Therefore, a new application field of the copy paper is expanded, and a new raw material is provided for manufacturing the building template.

Description

technical field [0001] The invention relates to the application of copy paper in the production of building templates, and belongs to the technical field of copy paper application. Background technique [0002] my country's forest resources are very scarce, and the contradiction between timber supply and demand is prominent. The building formwork in the prior art is composed of two skins and a core layer, the core layer is arranged between the two skins, and the core layer is formed by sequentially bonding multiple layers of wood chips. The production method is: use the dough to make the base and cover the surface, then pass the surface glue through cold pressing, and finally make the surface glue form a protective film on the surface of the dough under high temperature and high pressure conditions, and use the good wear resistance and chemical resistance of the glue after forming. Stability to play a certain role in the protection of building formwork. However, in the pro...
