Electrically-induced-heating functional composite water-proof material and preparation method thereof

Abstract

The invention discloses an electrically-induced-heating functional composite water-proof material and a preparation method thereof. The electrically-induced-heating functional composite water-proof material comprises two water-proof substrate layers and an electric heating layer positioned between the water-proof substrate layers, wherein the electric heating layer is made of an electric heating material; at least two intercepting bars are paved in the electric heating layer or between the electric heating layer and the water-proof substrate layers at certain distances. The preparation method of the electrically-induced-heating functional composite water-proof material comprises the following steps: fixing the intercepting bars on the surface or inside of the electric heating layer; compounding the water-proof substrate with the upper and lower surfaces of the electric heating layer in sequence or simultaneously. The electrically-induced-heating functional composite water-proof material has the same water-proofing performance as the conventional water-proof material, and has a heating function; the voltage is adjustable between 1.5V and 220V, and the surface temperature is adjustable between 5 DEG C and 160 DEG C; the heating time is 5-600 seconds before a set temperature is reached; in a heating process, far infrared waves in wave bands of 4-15 micrometers are released in the heating process, and the releasing equivalent of the far infrared waves is up to 50-95 percent.

AI Technical Summary

Problems solved by technology

[0004] At present, there are some heating materials on the market, such as electric heating film, carbon crystal, heating cable, etc. However, these materials need to be added with waterproof and moisture-proof materials during the construction process to prevent leakage and fire during later application. The occurrence of accidents will not only affect the heating and heating effect of the material, but also increase the construction cost. Therefore, there is an urgent need for the emergence of a composite waterproof material that not only has the functions of waterproof and moisture-proof, but also has the function of energizing and heating.
