Problems solved by technology

However, in areas where wear resistance and scratch resistance are required (such as furniture, floors, etc.), the coating needs to add inorganic fillers with higher hardness to achieve better performance, but the addition of inorganic fillers will significantly affect the film pressure. The mirror effect of the process reduces the product qualification rate

Abstract

The invention discloses a preparation process of a radiation curing coating, which comprises the following steps: (1) coating a carrier film with a radiation curing coating A and carrying out radiation curing to obtain a pre-coated film; (2) coating a radiation curing coating B on a substrate, then pasting the pre-coating film on the radiation curing coating B, and enabling the coating surface of the pre-coating film to be in contact with the radiation curing coating B to obtain a coating precursor; and (3) performing radiation curing on the coating precursor, and removing the carrier film to obtain the radiation curing coating. The invention also provides a radiation curing coating prepared by the radiation curing coating process and an application of the radiation curing coating. The preparation process disclosed by the invention has the advantages of strong tolerance to a construction environment, no oxygen inhibition influence, no consumption of radiation curing energy by the carrier film, no limitation on the addition amount of an inorganic functional filler and good mirror surface effect, and can be used for preparing a mirror surface coating with micro-scratch resistance reaching B1 level and traffic scratch resistance reaching C2 level so as to achieve the effect of replacing ceramic tiles and marble.

Description

technical field [0001] The invention belongs to the field of building decoration materials, and in particular relates to a coating preparation process, coating and application thereof. Background technique [0002] The coating can present a variety of surface effects due to the different surface morphology of the substrate and the coating process. Among the different surface effects, the mirror smooth effect is widely used in decorative panels, furniture, floors, ceramic tiles, and films because of its unique beauty. and other fields. Commonly used coating techniques that can obtain a smooth mirror surface are spray coating, laser roller coating, curtain coating and film pressing. Among them, the spraying process has defects such as environmental pollution, complicated operation, and limited performance; the laser roller coating and shower coating process have high requirements for coatings, which require low viscosity, excellent defoaming properties, good leveling properti...
