Abstract

The invention relates to a preparation method of a heat-preservation and heat-insulation tent composite fabric, and belongs to the technical field of textile fabrics. Polyimide modified silicon dioxide aerogel is used as a coating, a fabric prepared from polyurethane modified polybenzimidazole fibers is used as base cloth, the coating is coated between the two layers of base cloth, and the heat-preservation and heat-insulation tent composite fabric is prepared through hot pressing and has good weather resistance, flame retardance, water resistance, ultraviolet resistance and other functions. The polybenzimidazole fiber has outstanding high temperature resistance and good waterproof performance; the silicon dioxide aerogel has the obvious characteristics of a nanometer material; good optical performance, sound absorption performance, chemical stability, environmental protection performance and excellent heat preservation and heat insulation performance are realized; polyimide has good mechanical property and flexibility and low thermal conductivity, and the prepared film has good flexibility and can be bent and folded, so that the polyimide modified silicon dioxide aerogel has goodmechanical property and thermal insulation property.

Description

technical field [0001] The invention relates to a preparation method of a thermal insulation tent composite fabric, which belongs to the technical field of textile fabrics. Background technique [0002] With the improvement of people's living standards, the rapid development of tourism has driven the development of outdoor textiles, and the demand for outdoor camping tents is increasing. The requirements for tent textiles are also getting higher and higher. In addition to basic waterproof and tear-resistant properties, tent textiles also require higher performance such as thermal insulation, UV protection, radiation protection, and infrared stealth. [0003] Lining the tent with a film insulation material with good thermal insulation performance is a simple and effective measure to improve the thermal insulation performance of the tent. This requires that the thermal insulation material must not only have good thermal insulation performance, but also have Very good foldabil...
