Problems solved by technology

This method can be used to produce glass fiber cloth, asphalt waterproof membrane and other products, but it has the problems of volatile organic matter polluting the environment and high energy consumption
The lamination method is a method of laminating the pre-made PVC film and the substrate on the laminator to obtain artificial leather. This method has many production processes, and the plastic film needs to be processed first, and then the lamination is carried out. The energy consumption is large and the production cost is high. high

Abstract

The invention discloses an ageing-resistant heat-insulation tarpaulin. The tarpaulin is composed of a polymer cloth base and an ageing-resistant heat-insulation coating which is coated on the polymer cloth base in a casting mode. After aging is quickened for 236 hours by simulating natural manual work, the tensile strength of the tarpaulin is improved by at least 10%, the elongation at break thereof is improved by at least 5% than the elongation at break before aging, the ultraviolet reflectivity thereof is more than or equal to 80%, and the infrared obstruction rate thereof is more than or equal to 85%. The invention also discloses a preparation method thereof, comprising the following step: pretreating a heat-insulation material by utilizing a surface treating agent; and premixing the heat-insulation material with accessory ingredients such as vinyl type polymer, antioxidant and the like, then putting the heat-insulation material and the accessory ingredients into a double-screw extrusion casting coating machine to be fused, plasticized and extruded out to be casted and coated on the polymer fiber cloth base, and carrying out cooling shaping and reeling by utilizing a cooling roll to obtain the ageing-resistant heat-insulation tarpaulin. The tarpaulin product obtained by the invention has favourable water proofness, heat-insulating property and ageing-resistant property, wide application range, no pollution in the production process, small energy consumption, low cost and easy popularization and application.

Description

technical field [0001] The invention belongs to the technical field of tarpaulin products and production methods thereof, and in particular relates to a tarpaulin with anti-aging heat insulation performance prepared by extrusion casting and coating a cloth base and a production method thereof. Background technique [0002] Tarpaulin, also known as coated cloth, is a waterproof product made of polymer coated on the cloth base, mainly used in occasions that require waterproof, dustproof and barrier. Specifically, it can be used as clothing, labor protection supplies, logistics packaging, tarpaulins for automobiles, tents for travel and living, and waterproofing for building roofs. [0003] Common tarpaulins include PVC flame-retardant waterproof tarpaulin, polyester waterproof tarpaulin, polypropylene waterproof tarpaulin, asphalt waterproof membrane, etc. Polyvinyl chloride flame-retardant waterproof tarpaulin is a coated cloth composed of double-sided coated polyvinyl chlor...
