Surfboard canvas and preparation method thereof

Abstract

The surfboard canvas and a preparation method thereof. The surfboard canvas is characterized by comprising a double-layer wire drawing base cloth; the upper and lower surfaces of the double wire drawing base cloth are coated with a PVC paste resin layer, the outer surface of the PVC paste resin layer is adhered with a polypropylene calendering film; the double-layer wire drawing base cloth comprises an upper base cloth and a lower base cloth; a plurality of terylene connection wires are arranged between the upper base cloth and lower base cloth; the connecting parts of the upper base cloth and lower base cloth with the plurality of terylene connection wires are provided with a viscose layer for bonding the base cloth andterylene connection wires. The product of the invention has the characteristics of no seam, no toxicity, no taste, acid and alkali resistance, impact resistance, high temperature resistance, aging resistance, freezing resistance and permeability resistance, and the advantages of reaching national standard GB 6675, United States ASTMF- 963, and EU EN-71.

Description

Technical field: [0001] The invention mainly relates to the technical field of canvas manufacture, in particular to a canvas for surfboards and a preparation method thereof. Background technique: [0002] At present, most of the surfboards on the market are plastic products, but plastic products are easy to age, and are easy to break and leak, and are not easy to repair, so the scope of application is limited; at present, there are also surfboards made of canvas materials, but the existing surfboards made of canvas materials It has the disadvantages of weak anti-ultraviolet performance, low peeling strength, not cold resistance, and poor air tightness; in addition, due to the use in seawater, due to the high salinity of seawater, the use environment is complicated, and the impact force is large, so surfboards need high breaking strength , anti-corrosion and good shape, but due to the limitations of canvas surfboards, it cannot be widely used.

Problems solved by technology

[0002] At present, most of the surfboards on the market are plastic products, but plastic products are prone to aging, damage and air leakage, and are not easy to repair, so the scope of application is limited; there are also surfboards made of canvas materials, but the existing surfboards made of canvas It has the disadvantages of weak anti-ultraviolet performance, low peeling strength, no cold resistance, and poor air tightness; in addition, due to the use in seawater, due to the high salinity of seawater, the use environment is complex, the impact force is large, and surfboards need high breaking strength , anti-corrosion and good shapeability, but due to the limitations of canvas surfboards, it cannot be widely used
