Electric-conductive heating glue and preparation method thereof

Abstract

The invention relates to electric-conductive heating glue which includes following components, by mass: 15-45 parts of a electric-conductive heating filling material, 60-85 parts of polyethylene resin, 15-40 parts of ethylene copolymer resin, 1-5 parts of a dispersing agent and 0.1-2 parts of an anti-oxidizing agent. The electric-conductive heating glue not only is safe to use and can maintain uniform heating for long period, but also has a bonding effect. The invention also provides the preparation method of the electric-conductive heating glue. The electric-conductive heating glue can satisfy development requirements in the following fields: electric-heating building materials, household appliances, equipment shields, antifreezing devices and the like products.

Description

technical field [0001] The invention relates to a glue, especially a conductive heat-generating glue (including glue particles, glue films or glue powder); meanwhile, it also relates to its production process, which belongs to the technical field of electrothermal materials. Background technique [0002] Conductive heating materials mainly play the role of conductive heating in the field of conductive heating composite panels. With the improvement of people's living standards, the requirements for the comfort of the living environment are getting higher and higher. Heating equipment such as air conditioners and heaters cannot meet people's needs. Heating methods have been generally accepted by consumers. Because with the further improvement of environmental protection requirements, the traditional heating methods using oil, gas, and coal consume a lot of energy and produce a lot of pollutants, and the heat conversion efficiency is low. Therefore, low-energy and high-efficie...

Problems solved by technology

If the carbon fiber heating paper is applied to the floor, there are the following problems: 1) the papermaking process is likely to cause uneven distribution of carbon fibers and graphene in the paper; 2) additional adhesives are required, and the process is complicated; 4) Due to the poor ductility of the paper, it will be torn due to thermal expansion and contraction during use, which will easily generate arcs and pose a safety hazard

However, there are actually the following problems: 1) the process of coating or impregnating the conductive heat-generating paint on the substrate can easily cause the conductive heat-generating matrix material in the conductive heat-generating paint to be unevenly distributed on the surface of the substrate; 2) an additional adhesive is required , the process is complex; 3) The adhesive will penetrate into the conductive heating coating during the cur
