Manufacturing method of PVC anti-skid heat preservation tarpaulin

Abstract

The invention provides a manufacturing method of PVC anti-skid heat preservation tarpaulin. The manufacturing method comprises: a, a step of purchasing, namely a step of purchasing existing polyestercanvas, foaming coiled materials and heating wires on the market; b, a step of burdening, namely a step of weighing 100 parts by weight of PVC paste resin, 50-70 parts by weight of a plasticizer, 2-8parts by weight of a stabilizer, 5-15 parts by weight of a flame retardant, 10-16 parts by weight of a mildew preventive, 3-9 parts by weight of an anti-aging agent and 2-10 parts by weight of pigment, putting the weighed materials into a stirrer, and performing heating and uniform stirring to obtain a paste material; c, a step of blade coating, namely a step of coating the outer side surface of the polyester canvas with the paste material through a coating device; d, a step of drying, namely a step of putting the scraped polyester canvas into a drying oven for drying; e, an attaching step, namely a step of attaching the foaming coiled material and the electric heating wire to the inner side surface of the polyester canvas through glue, and enabling the electric heating wire to be positioned between the foaming coiled material and the polyester canvas, so as to obtain the finished PVC anti-skid heat-insulating tarpaulin. The preparation method has the advantage of simplicity and convenience in preparation.

Description

technical field [0001] The invention belongs to the technical field of tarpaulin processing, and relates to a manufacturing method, in particular to a manufacturing method of a PVC anti-slip heat-retaining tarpaulin. Background technique [0002] Tarpaulin (or tarpaulin) is a waterproof material with high strength, good toughness and softness. It is often used as canvas (canvas), polyester with polyurethane coating or made into polyethylene plastic. Tarps usually have strong grommets at the corners or edges for easy rope tying, hanging or covering. Nowadays, there are many kinds of tarpaulins with different functions, such as waterproof tarpaulins, fireproof tarpaulins, car tarpaulins and so on. [0003] After searching, for example, Chinese patent literature discloses a tarpaulin [application number: 201310603975.9; publication number: CN103643837A]. This tarpaulin is characterized in that it includes at least three layers of inner, middle and outer layers, wherein the in...

Problems solved by technology

[0004] Although the tarpaulin disclosed in this patent improves the heat insulation effect, the tarpaulin does not have a corresponding manufacturing method, and the production is cumbersome. Therefore, it is necessary to design a manufacturing method of a PVC non-slip thermal insulation tarpaulin.
