Problems solved by technology

[0004] The purpose of the present invention is to provide a new type of image transfer film for prefabricated concrete slabs, which solves the problem that the retarder will scatter when the slabs are poured with mortar or concrete after vibration, so that self-leveling and self-compacting concrete must be used. High cost, high technical threshold of concrete material ratio and complicated process

Abstract

The invention discloses a novel image transfer printing film for a precast concrete plate. The novel image transfer printing film comprises a base mold and a retarder, the retarder is added into papermaking paper pulp and is made into a retarding base film through papermaking, and a pattern is added to the film surface of the retarding base film so as to obtain the transfer printing film. According to the novel image transfer printing film, the retarder can release in the concrete after paper is completely wetted by water, so that certain buffering time can be achieved, and in this time period, a vibrating platform can be used for vibrating to enable concrete or mortar to be flat and compact. After the concrete is demoulded, water erosion is carried out, and a decorative surface with an exposed aggregate pattern facing and a plain concrete base surface forming comparison and concave-convex change is formed on the surface of the concrete, so that the retarder can not be dispersed even being vibrated.

Description

technical field [0001] The invention relates to the technical field of plate decoration, in particular to a novel image transfer film for prefabricated concrete plates. Background technique [0002] The existing transfer film on the market includes a PVC base film and a retarder coating. The retarder coating is attached to the surface of the base film. The area of ​​the retarder is smaller than the area of ​​the base film. The retarder is coated on the base film with a film structure. pattern area. During production, the transfer film is laid on the bottom of the mold, and self-leveling and self-compacting concrete is poured. After the concrete is demoulded, it is eroded by water to form a decorative surface on the surface of the concrete in which the exposed aggregate pattern is compared with the plain concrete base surface and the unevenness changes. [0003] In the existing retarding transfer film, the water-soluble retarder is attached to the surface of the transfer fil...
