Heat discoloration composite material and preparation method thereof

Abstract

The invention discloses a heat discoloration composite material and a preparation method thereof, wherein the heat discoloration composite material comprises a base cloth layer; one side of the base cloth layer is connected with a heat discoloration PVC composite surface layer, the other side of the base cloth layer is connected with a heat discoloration PVC bottom layer, and the heat discoloration PVC composite surface layer is formed by compounding a transparent PVC film and a heat discoloration PVC film. The thermochromic composite material is designed according to existing requirements, different thermochromic pigments can be designed to be matched with conventional pigments, various color combinations are presented, the thermochromic film is made into a semitransparent effect, the use amount of the pigments is reduced, the cost is reduced, the color changing effect is not affected, and the surface effect of the thermochromic composite material is improved; the color changing effect of the material outside the temperature change critical point is obvious, the base cloth layer, the thermochromic PVC composite surface layer and the thermochromic PVC bottom layer can be evenly preheated before being attached, the attaching tightness is guaranteed, and the produced thermochromic composite material is stable in structure and smooth in surface after being attached.

Description

technical field [0001] The invention relates to the technical field of thermochromic materials, in particular to a thermochromic composite material and a preparation method thereof. Background technique [0002] Space cloth material is a new type of material that has developed rapidly in recent years. Due to its unique wire drawing structure design and weaving technology, the products produced have excellent dimensional stability and surface smoothness, and are widely used in surfboards and inflatable gymnastics. Mats, yoga mats, etc. However, after years of development, the style of space cloth or accessories materials on the market is relatively single, especially for SUP boards, the main difference is the appearance color. [0003] Thermochromic material refers to the molecular structure of the organic substance changes due to electron transfer at a specific temperature, thereby realizing color transformation. This feature can add some new special functions and personal...
