Heating element for floor or ceramic tile and preparation method

Abstract

The invention discloses a heating element for a floor or ceramic tile and a preparation method. The heating element adopts a balanced adhesive tape layer, an oriented structural particleboard, a carbon fiber chip paper layer, a woodgrained paper layer and a wear-resistant layer which are sequentially laminated, wherein the diameter of carbon fibers in the carbon fiber chip paper layer is 300nm, the carbon fibers are compounded by adopting short fibers and long fibers, and an aluminum foil electrode and a copper electrode are arranged at two ends of the carbon fiber chip paper layer and the oriented structural particleboard and are mutually connected. According to the invention, long and short fiber wood pulp and carbon fibers are sufficiently mixed and then made into carbon fiber chip paper; the paper and the oriented structural particleboard are solidified and combined in a balanced hot-pressing mode, then a balanced adhesive tape, the woodgrained paper layer and the wear-resistant adhesive tape layer are respectively covered, and the aluminum foil electrode and the copper electrode are set to obtain the heating element. The heating element and the preparation method overcome defects of the traditional heating floor or ceramic tile, the heating is uniform, and there is no local overheating. In addition, the heating element is reliable in combination with the floor or ceramic tile body, and the ground quality after the laying is ensured.

Description

technical field [0001] The invention relates to a heating body for floors or ceramic tiles and a preparation method. Background technique [0002] With the development of science and technology and the improvement of people's living standards, heating floors or heating tiles are widely used. By setting a heating element on the back of the floor or tiles, the heating element can continuously generate heat and release it to the indoor space after being powered on. heating purpose. At present, most of the traditional heating elements are carbon fiber heating materials, which are woven into heating wires with carbon fiber filaments, fixed on the floor or the back of tiles by winding, or made into carbon fiber heating films. Usually, the heating element does not design the length distribution of carbon fibers, resulting in uneven heating, prone to local overheating, affecting the physical properties of the floor or tiles, and there is a risk of carbonization of the floor. In ad...

Problems solved by technology

Usually, the heating element does not design the length distribution of carbon fibers, resulting in uneven heating, prone to local overheating, affecting the physical properties of the floor or tiles, and there is a risk of carbonization of the floor

In addition, the outer plastic of the carbon fiber heating film is not firmly combined with the floor wood substrate or the ceramic tile body, and quality problems such as delamination are prone to occur, which seriously affects the quality of the ground after laying
