Problems solved by technology

[0002] In the process of building construction, there are some procedures that require workers to use plastic film to seal some cement or steel bars and other materials that have just been constructed, so as to ensure that in the subsequent construction process, this part of the completed part will not be affected by other The impact of the use of the unfinished part, and because the construction of this part is completed earlier, if it is exposed to the external environment prematurely, this will lead to a decrease in the service life of this part, so construction personnel need to add a sealing film on it be protected

Abstract

The invention provides a sealing film for building construction. The sealing film is prepared by the steps: firstly, coating a bottom film with adhesives and placing a heat insulation layer on the adhesives; forming a buffer layer on the heat insulation layer after the heat insulation layer is coated with adhesives; coating the buffer layer with adhesives and attaching a non-woven fabric onto thebuffer layer; forming a bottom layer of a top film on the non-woven fabric, adding a reinforcing net onto the bottom layer, forming a top layer of the top film on the reinforcing net and performing calendering vulcanization once to form the sealing film for casting a wall. As the non-woven fabric is arranged on the inner side of the top film, other sealing film layers in the top film can be protected from being damaged by sharp articles, and the service life of the sealing film is prolonged.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a sealing film for building construction. Background technique [0002] In the process of building construction, there are some procedures that require workers to use plastic film to seal some cement or steel bars and other materials that have just been constructed, so as to ensure that in the subsequent construction process, this part of the completed part will not be affected by other The impact of the use of the unfinished part, and because the construction of this part is completed earlier, if it is exposed to the external environment prematurely, this will lead to a decrease in the service life of this part, so construction personnel need to add a sealing film on it be protected. Contents of the invention [0003] The invention overcomes the deficiencies in the prior art and provides a sealing film for building construction. [0004] The purpose of the present...
