Abstract

The invention relates to a far-infrared anion carbon crystal electric-heating warm-keeping composite material and a preparation method thereof, and specifically provides a far-infrared anion carbon crystal electric-heating warm-keeping composite material and a preparation method thereof. The far-infrared anion carbon crystal electric-heating warm-keeping composite material aims to solve problems that an electric-heating warm-keeping material of the prior art has uneven heat radiation and poor environment effect and the like, and is used for manufacturing electric-heating plates for warm-keeping. The far-infrared anion carbon crystal electric-heating warm-keeping composite material comprises the following ingredients in percentage by weight: 70-95% of paper pulp, 2-20% of carbon nano fiber, 2-5% of nano far-infrared anion powder, and 1-5% of diffusant. According to the invention, a conductive composite material is prepared by using the paper pulp, carbon nano fiber, nano far-infrared anion powder and diffusant as raw materials through working procedures of pulping, beating, pulp mixing, paper making, drying, up-coiling and the like. A working procedure of mixed feeding during the beating procedure is added, that is, the carbon nano fiber, the diffusant and the nano far-infrared anion powder are added into the paper pulp uniformly. The invention has functions of far-infrared transmission and anion emission simultaneously, and harmful charges can be released effectively, thereby realizing effects of purification, sterilization and environment protection.

Description

technical field [0001] The invention relates to an improvement technology of an electrothermal heating composite material, in particular to a far-infrared anion carbon crystal electrothermal heating composite material and a preparation method thereof. Background technique [0002] At present, in addition to infrared heating products such as metals and non-metals, electric heating products made of carbon fiber conductive materials are also developing rapidly. Carbon crystal is a heating product of modified and purified carbon particles. It is modified by short carbon fiber and then ball-milled to make microcrystalline particles, then added with far-infrared emitter, and synthesized by a special process to make a heating element. Although carbon fiber electric heating products have many advantages, such as: stable electrical conductivity, high strength, small specific gravity, thin thickness, easy to use, etc., they also have poor heating uniformity, hot spots, and large tempe...
