Abstract

The invention discloses a high-strength canvas. The high-strength canvas consists of grid cloth having two sides coated with PVC coating layers. A raw material formula of the PVC coating layers includes the following components in parts by weight: 80 parts of PVC paste resin, 10-30 parts of chlorinated polyethylene, 40-85 parts of dioctyl phthalate, 1-8 parts of anatase titanium dioxide, 0.1-2 parts of cotton yarns, 3-6 parts of a stabilizer and 1-6 parts of an adhesive. The high-strength canvas has the cotton yarns added in the PVC coating layer formula, not only can the heat insulation and heat preservation performance of the high-strength canvas be increased, but also entanglement between the cotton yarns and the grid cloth of the canvas can be formed, and the bonding strength between the coating layers and the grid cloth is increased, so that the prepared PVC canvas has the characteristics of high strength and high toughness.

Description

technical field [0001] The invention relates to a high-strength canvas. Background technique [0002] PVC canvas is double-sided coated PVC paste resin base fabric. Compared with ordinary PE tarpaulins, PVC tarpaulins are far superior to PP and PE tents in rain resistance, and are widely used in tents, automobiles, trains, storage and other fields. In addition, PVC is low in cost, rich in sources, non-toxic, and is a membrane material worth promoting. Although cheap, the existing PVC canvas has the disadvantages of low strength and poor toughness. Contents of the invention [0003] The object of the present invention is to overcome the defects in the prior art and provide a high-strength canvas. [0004] In order to realize the purpose of the present invention, the technical solution of the present invention is: a kind of high-strength canvas, it is made up of double-sided coating PVC coating of grid cloth, and the raw material formula of described PVC coating comprises...
