Problems solved by technology

In the prior art, adding hollow glass microspheres to the tent coating can indeed achieve a better heat insulation effect, but it has a fatal shortcoming. It is easy to crack after being bent, and the tent usually wears out after each use. It needs to be folded and placed, which greatly affects the service life of the tent
The existing technology only considers the thermal insulation performance of microbeads, but does not consider that it will reduce the performance of the coating

Abstract

The invention relates to a preparation method of a folding-resistant and heat-insulating tent fabric, and belongs to the technical field of outdoor tents. Hollow glass beads and asbestos powder are subjected to rare earth modification treatment to improve the interface performance with polyurethane, and a heat-insulating tent is obtained in a layered coating mode. The folding-resistant and heat-insulating tent fabric is good in shading and heat insulation performance, has folding resistance and stripping resistance, and can meet the tent standard of light weight and convenient carrying.

Description

technical field [0001] The invention relates to the technical field of outdoor tents, in particular to a preparation method of a folding-resistant and heat-insulating tent fabric. Background technique [0002] With the development of society and the continuous improvement of people's living standards, outdoor life experience has become an important part of life. Tourist tents are gradually being used by the masses, and they are also the best-selling tent types on the market. In order to facilitate carrying and handling, tent fabrics are relatively light and thin. At present, lightweight tent products are made of low-denier polyester fabrics, such as 15D, 20D and other filaments for weaving and processing, and are coated with PVC, PU and other silver glue coatings inside. In summer, a large amount of radiant heat from sunlight still enters the tent, causing the temperature to continue to rise, and the phenomenon of overheating in sunlight occurs, causing inconvenience to outd...
