Problems solved by technology

This kind of tarpaulin is generally rough and bulky, with poor surface quality, low mechanical properties, easy aging, short service life, and inconvenient construction.
For example, the tarpaulins of the Ministry of Railways weigh more than 50kg each, and a forklift must be used during construction, which will not only easily cause the wear of the cloth surface but also bring great trouble to the construction.

Abstract

The invention provides a novel environment-friendly waterproof flame-retardant awning fabric, which comprises a base cloth layer, a bonding bottom layer and a bonding surface layer that are sequentially compounded, wherein the base cloth layer is nylon silks; the bonding bottom layer comprises the following components in parts by weight: 90-110 parts of polyether urethaner, 5-8 parts of underlayercuring agent, 15-20 parts of bottom layer solvent; the bonding surface layer comprises the following components in parts by weight: 90-110 parts of flame retardant polyurethane, 0.5-1 part of surfacecuring agent, and 5-10 parts of surface solvent. The novel environment-friendly waterproof flame-retardant awning fabric overcomes the deficiency of the prior art, and provides an overcanopy fabric material which is light in weight, high in strength and wear-resistant.

Description

technical field [0001] The invention belongs to the field of boat tarpaulins, and in particular relates to a novel environmentally friendly waterproof and flame-retardant boat tarpaulin and a preparation method thereof. Background technique [0002] In recent years, tarpaulins have been widely used in military and civilian tarpaulins, stations, port terminals, field operations, vehicle and ship transportation, and storage yards, etc., and are a new economic growth point for the textile industry. With the development of the national economy and the continuous increase of cargo transportation, the demand for tarpaulins used in the transportation industry is showing a growing trend. At present, 90% of my country's tarpaulins are traditional tarpaulins based on pure cotton canvas, polyester cotton canvas, PVC coated cloth, PE cloth, Oxford cloth, biaxial cloth, vinylon or polyester staple fiber base cloth. . This kind of tarpaulin is generally rough and heavy, with poor surface...
