Problems solved by technology

[0003] Insulation fabrics can maintain the temperature of the human body, and keep the temperature from rising or falling due to the influence of the external environment to the maximum extent, which improves the comfort of the fabric. At present, most of the constant temperature fabrics on the market are mainly thermal insulation fabrics, which can improve the insulation of the fabric in cold environments. However, when used in a hot environment, the human body will often be stuffy, that is, affected by the high temperature outside, the temperature inside the thermal insulation fabric will increase, and its thermal insulation effect is not obvious in a hot environment, that is, it cannot isolate the effect of high temperature

Abstract

The invention relates to the technical field of functional fabrics, and particularly provides a heat preservation fabric based on graphene and a preparation method of same. The heat preservation fabric includes a glue coating layer coating an inner layer and / or an outer layer of a base cloth layer, thickness of the glue coating layer being 10-20 [mu]m. An EVA glue film is attached to the glue coating layer. The glue coating layer includes, by weight, 20-45 parts of high-molecular resin glue, 0.1-3 parts of rutile titanium dioxide, 2-8 parts of glass microbeads, 0.2-1.5 parts of graphene, and 0.2-1 part of polycrystalline silicon. The glue coating layer is rich in rutile titanium dioxide, so that light can be effectively reflected and temperature increasing is avoided due to the light beam. Especially, infrared light is reflected, thus reducing heating effect. Meanwhile, the glass microbeads have hollow structure, so that heat conductivity is effectively reduced. The graphene itself has excellent heat-dissipating performance, so that the fabric is a high-effective, environment-friendly and energy-saving heat-supply material at a low environment temperature.

Description

technical field [0001] The invention relates to the technical field of functional fabrics, in particular to a graphene-based thermal insulation fabric and a preparation method thereof. Background technique [0002] Fabric is the material used to make clothing. As one of the three elements of clothing, fabric can not only interpret the style and characteristics of clothing, but also directly affect the color and shape of clothing. In the big world of clothing, there are various fabrics for clothing. Every day. But generally speaking, high-quality and high-end fabrics mostly have the characteristics of comfortable wearing, sweat-absorbing and breathable, crisp drape, noble vision, and soft touch. With the improvement of living standards, people have higher and higher requirements for clothing, especially for multi-functional fabrics with special properties, environmental protection and comfort. [0003] Insulation fabrics can maintain the temperature of the human body, and k...
