Abstract

The invention discloses high-strength PVC (Polyvinyl Chloride) awning cloth which is formed by coating both sides of gridding cloth with PVC coatings. According to a raw material formula, each PVC coating comprises the following components in parts by weight: 80 parts of PVC paste resin, 70-90 parts of dioctyl phthalate, 55-65 parts of calcium carbonate, 3-6 parts of chlorinated paraffin, 3-6 parts of a stabilizer, 3-10 parts of de-aromatic solvent oil, 1-8 parts of a vinylpyridine bonding agent, 7-20 parts of flame retardant mortar, 3-8 parts of titanium dioxide, 0.1-0.8 part of an anti-UV (Ultraviolet) agent and 2-30 parts of heat insulation powder. The heat insulation powder is a mixture prepared from hollow glass beads and polyvinyl acetate according to the weight part ratio of 100: (1-5). Compared with the prior art, the awning cloth has the advantages that the tensile strength is up to 3,300N/30mm, the ultraviolet reflectivity and infrared ray blocking rate are up to 95%, and the favorable mechanical property stability is kept after an ageing test is ended.

Description

technical field [0001] The invention relates to a PVC tarpaulin, in particular to a high-strength PVC tarpaulin. Background technique [0002] The PVC tarpaulin is a double-sided coated PVC paste resin for the 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. However, the PVC tarpaulin produced by the prior art has defects such as low strength, fire resistance, and easy aging, which can no longer meet the needs of the market. 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 PVC tarpaulin. [0004] In order to realize the object of the present invention, the technical solution of the present invention is: a kind of high-strength ...
