Thermal-insulation and waterproof composite material

Abstract

The invention relates to a thermal-insulation and waterproof composite material, belonging to the field of thermal-insulation and waterproof materials. The thermal-insulation and waterproof compositematerial sequentially comprises a nano-silicon dioxide sol layer, a polytetrafluoroethylene micro-pore film layer, an oxford cloth layer and a thermal insulation layer, wherein the thermal insulationlayer is produced from a thermal-insulation cotton material and particularly contains the following components in parts by weight: 20-30 parts of clay clinker, 10-15 parts of alumina powder, 10-30 parts of silica powder, 20-30 parts of chromium-quartz powder, 10-15 parts of silk fibers and 2-3 parts of sepiolite nano-fibers. The thermal-insulation and waterproof composite material comprises an outer thermal insulation layer and an inner waterproof layer and can meet thermal insulation requirements, and the energy consumption can be reduced; and the waterproof layer is formed by laminating a polytetrafluoroethylene micro-pore film and coating with a nano-silicon dioxide sol by taking oxford cloth as a base layer and has excellent waterproof performance, and the service life can be guaranteed.

Problems solved by technology

[0002] In daily life, the fabrics of tents that people use when camping are mostly waterproof fabrics, but because they cannot be well ventilated, the interior will be stuffy, and the existing fabrics have insufficient thermal insulation effect, which cannot keep the tent inside well. temperature

Existing fabrics for the production of clothes are generally made of one kind of material, and the characteristics are relatively single, resulting in that the softness and air permeability of the fabric cannot be obtained at the same time. After repeated use or washing, it is easy to change shape. The softness of the clothes is reduced, which will greatly reduce the comfort of wearing clothes. At the same time, the silk thread structure of the fabric is relatively simple, which will cause the deflection of the needle holes in the fabric obtained by weaving, which will affect the visual effect of the fabric, and even cause the fabric to sag. scrapped

[0003] At present, the fabric has the effect of heat preservation, and the method of adding layers and thickening is often used. Although the effect of heat preservation is achieved, the thickness and weight of the fabric are increased, which reduces the texture and feel, and the moisture permeability is also greatly reduced.
