Abstract

The invention discloses a cloth-grain-imitated PVC mat and a preparation method thereof. The cloth-grain-imitated PVC mat comprises a base layer and a printed surface layer, wherein the base layer comprises a PVC foamed layer and base cloth embedded in the PVC foamed layer, wherein the printed surface layer is attached to the PVC foamed layer, the printed surface layer comprises a PVC surface layer body and a printed layer body, the PVC surface layer body is prepared through calendaring molding, and the printed layer is a cloth-grain-imitated printed layer. The preparation method comprises thesteps of preparation of the printed surface layer, preparation of the base layer and composite foaming. According to the cloth-grain-imitated PVC mat and the preparation method thereof, the purpose of printing special grains and patterns on the PVC mat is achieved by arranging the printed surface layer and the base layer which are made of PVC materials; the PVC surface layer is prepared through acalendering forming process, so curling and pattern printing are facilitated; a calendered PVC film is good in binding force with the base layer and ink and does not fall off; and the printed surfacelayer obtained after printing not only has excellent wear resistance and scratch resistance, but also has an ornamental effect, so the grade of the PVC mat is greatly improved.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a cloth-like PVC mat and a preparation method thereof. Background technique [0002] Yoga is a relatively fashionable sport in today's society, and yoga mats are indispensable equipment for yoga sports. Existing yoga mats are usually made of PVC, PE, EVA and other materials, all of which have certain elasticity and wear resistance. Can provide protection for yogis. PVC yoga mats are popular among consumers because of their cheap price and good elasticity. The thickness of the molded plastic is relatively thick, which is not convenient for printing patterns, and it is easy to deform the patterns during the foaming process. Therefore, the existing yoga mats generally have single patterns and colors, and are basically monochrome products without patterns or textures. , poor viewing effect. There is also a way to enrich the color and pattern of the yoga mat by means of s...
