Pattern aligning hot-pressing process of stone-plastic floor

Abstract

The invention discloses a pattern aligning hot-pressing process of a stone-plastic floor. The process comprises the following steps that A, all layers of materials are prepared, wherein a stone-plastic base material layer, a wear-resistant layer and a color film layer are produced and manufactured, and when a pattern is printed on the color film layer, and a first cursor is marked on the edge of the color film layer; B, point making of a embossed plate is carried out, and specifically a second cursor is engraved on the pattern position, corresponding to the first cursor on the color film layer, of the bottom surface of the embossed plate; C, pattern alignment is carried out, wherein the embossed plate, the wear-resistant layer, the color film layer and the stone-plastic base material layer are placed from top to bottom, and the first cursor on the color film layer is aligned with the second cursor; and D, hot pressing is carried out, and specifically hot-pressing compounding is carried out on all the layers of materials stacked in the step C by utilizing a hot press. According to the pattern aligning hot-pressing process of the stone-plastic floor, the pattern alignment accuracy between surface embossing of the wear-resistant layer and the pattern of the color film layer can be improved.

Description

technical field [0001] The invention relates to the field of flooring, in particular to a flower-to-floor hot-pressing process for stone-plastic flooring. Background technique [0002] Plastic floor is a floor made of PVC as the main raw material, adding fillers, plasticizers, stabilizers, colorants and other auxiliary materials. During the manufacturing process, the color film layer and wear-resistant layer are generally hot-pressed on the surface of the floor. The decorative function is realized by the color film layer, and the scratch-resistant function is realized by the wear-resistant layer. In order to improve the decorative effect, the color film layer will present simulated patterns, such as some wood grains and annual rings. In order to achieve a better sense of simulation, The embossed board will be used to emboss the concave and convex lines on the surface of the wear-resistant layer to match the corresponding pattern trend, but in the production process, the line...

[0002] Plastic floor is a floor made of PVC as the main raw material, adding fillers, plasticizers, stabilizers, colorants and other auxiliary materials. During the manufacturing process, the color film layer and wear-resistant layer are generally hot-pressed on the surface of the floor. The decorative function is realized by the color film layer, and the scratch-resistant function is realized by the wear-resistant layer. In order to improve the decorative effect, the color film layer will present simulated patterns, such as some wood grains and annual rings. In order to achieve a better sense of simulation, It will rely on the embossed plate to emboss the concave and convex lines on the surface of the wear-resistant layer to match the corresponding pattern trend, but in the production process, the lines and patterns are often misaligned and the display effect and texture of the floor will be reduced.
