Abstract

The invention discloses a wooden floor based on carbon paper as a heating layer and a preparation method thereof, belonging to the technical field of decoration and heating. The invention adopts the papermaking wet forming technology to prepare the carbon fiber paper layer, and in addition, the polypyrrole is uniformly distributed on the carbon fiber paper layer by dipping and hot pressing technology to prepare a low-resistance heating layer, which can realize the function of low-voltage rapid heating, electrothermal conversion The highest efficiency can be as high as 98%; the heating layer has the characteristics of thinness, lightness and good uniformity, which makes the heat generation more uniform than other products made of carbon fiber, and the temperature uniformity is as high as 98%. The method of the invention is simple, green and environment-friendly, has mature technology, low cost, is beneficial to human health, and is suitable for industrialized production.

Description

technical field [0001] The invention relates to a wooden floor based on carbon paper as a heating layer and a preparation method thereof, belonging to the technical field of decoration and heating. Background technique [0002] Due to the increasing living standards of the people, the higher per capita income and heating demand, and the stronger ability to accept new things, new heating methods such as electric floor heating are easy to open up the market. Considering factors such as energy conservation and environmental protection, investment intensity, and heating costs, it is less feasible to construct a large-scale central heating system in southern areas that need heating. In contrast, household heating systems such as electric heating floors are more in line with the demand characteristics of "southern heating". It is green, environmentally friendly, safe and durable, and will usher in good development opportunities in the future. [0003] Carbon fiber is a new type o...
