SPC floor embossing process

Abstract

The invention discloses an SPC floor embossing process. The SPC floor embossing process comprises the following steps of (1) gluing, specifically, a base material subjected to dust cleaning is conveyed to a gluing machine, and the surface of the base material is coated with hot melt paint in a roller coating mode through the gluing machine; (2) drying, specifically, the glued base material is enabled to pass through a drying tunnel, and drying is conducted on a hot-melt paint film; (3) coating, specifically, the base material after the drying of the hot-melt paint film is conveyed to a coating machine, and the hot-melt paint film is coated with finish paint in a roller coating mode; (4) pre-curing and matting, specifically, the coated base material is conveyed to a matting machine, and the pre-curing and matting is conducted on the surface layer of the finish paint film; (5) drying, specifically, the pre-cured and matted base material is conveyed to a first UV drying machine, and the finish paint film is fully cured; and (6) embossing, specifically, the base material subjected to the finish paint film full curing is conveyed to an embossing machine, and grain and pattern embossing treatment is carried out on the surface of the base material.

Description

technical field [0001] The invention relates to the technical field of production of surface decoration materials, in particular to an SPC floor embossing process. Background technique [0002] In the field of home decoration, substrates such as wooden floors, PVC, LVT, WPC, and SPC floors all need paint coating protection. The coating not only needs to provide physical properties such as scratch resistance and wear resistance, but also provides visual perception of various texture patterns Appearance and touch; traditional substrate texture pattern processing process: when SPC substrates are produced and extruded, the color film layer and the wear-resistant layer, and the three-layer materials need to be composited together by heating and pressing with steel rollers. The texture needs to be embossed through the engraved lines on the surface of the steel roll. The lines pressed by the steel roll and the lines of the color film can be aligned neatly. The disadvantage of the t...

[0002] In the field of home improvement, substrates such as wooden floors, PVC, LVT, WPC, and SPC floors all need paint coating protection. The coating not only needs to provide physical properties such as scratch resistance and wear resistance, but also provides visual perception of various texture patterns Appearance and touch; traditional base material texture pattern processing process: when SPC base material is produced and extruded, it is necessary to combine the color film layer and the wear-resistant layer, and the three-layer materials are heated and pressed by steel rollers. The texture needs to be embossed through the engraved lines on the surface of the steel roll. The lines pressed by the steel roll and the lines of the color film can be aligned neatly. The disadvantage of the traditional technology is: after the SPC extrusion process is carried out after the grain embossing, after the finished product The SPC base material is difficult to paint the uneven surface, paint coating protection, and visual and tactile treatment. If the spraying process is used, the cost will be too high
