Problems solved by technology

The existing carbon fiber paper is mainly composed of carbon fiber and pulp to make paper. This kind of paper has uneven resistance, and carbon fiber is unevenly dispersed in the paper, resulting in uneven heat generation. Moreover, the paper is easy to break, the fastness is not high, and it is easy to tear. Wait

Embodiment Construction

[0012] A carbon fiber composite electric heating paper, made of the following raw materials in parts by weight (kg): carbon fiber 40, wood pulp 100, vinyl triethoxysilane 4, nanometer iron powder 3, polyvinyl acetate emulsion 3, sodium carbonate 1, Sepiolite powder 3, vermiculite powder 3, zinc chloride 2, boric acid 2, sodium persulfate 2, rapeseed oil 1, peanut shell powder 1, modified mica powder 4.

[0013] The modified mica powder is made of the following raw materials in parts by weight (kg): mica powder 12, attapulgite 3, aluminum nitride 2, n-butyl citrate 2, barium petroleum sulfonate 2, sodium metasilicate 3. Silane coupling agent KH550 2, dimethyl silicone oil 2, polyvinyl alcohol 2, morpholine 2; the preparation method is: mix the materials, add them to water with 8-10 times the amount of mica powder, and heat to 95-100 ℃, stir and cook for 2-3 hours, after cooling, dehydrate and dry, grind to get 200-300 mesh powder, then spray chlorinated paraffin equivalent to 1...

Abstract

The invention discloses carbon fiber composite electro-thermal paper and a preparation method thereof. The carbon fiber composite electro-thermal paper is prepared from the following raw materials in part by weight: 30 to 40 parts of carbon fibers, 100 to 120 parts of wood pulp, 3 to 4 parts of vinyl triethoxysilane, 3 to 4 parts of nano iron powder, 2 to 3 parts of polyvinyl acetate emulsion, 1 to 2 parts of sodium carbonate, 3 to 4 parts of sepiolite powder, 2 to 3 parts of vermiculite powder, 1 to 2 parts of zinc chloride, 1 to 2 parts of boric acid, 1 to 2 parts of sodium persulfate, 1 to 2 parts of rape seed oil, 1 to 2 parts of peanut hull powder, and 3 to 4 parts of modified mica powder. Compared with the traditional carbon fiber composite electro-thermal paper, the carbon fiber composite electro-thermal paper has the advantages that electric conductivity and stability of the electro-thermal paper are improved by adding the nano iron powder; the temperatures at different parts of the electro-thermal paper do not exceed 2 DEG C; and the carbon fibers in the carbon fiber paper are uniform in overall dispersion, so the electro-thermal paper is good in breaking resistance, has low probability of being torn and broken and can be conveniently processed into planar heating elements with different temperature requirements.

Description

technical field [0001] The invention relates to the technical field of electric heating materials, in particular to a carbon fiber composite electric heating paper and a preparation method thereof. Background technique [0002] Carbon fiber paper is a functional paper with special properties produced by using carbon fiber or activated carbon fiber and carbon fiber or activated carbon fiber mixed with other plant or non-plant fibers. Carbon fiber paper has many excellent properties, such as electrical conductivity, thermal conductivity, porosity, adsorption, etc., so it is widely used in energy, military, environmental protection, civil engineering, electronic appliances, heating and other fields. The existing carbon fiber paper is mainly composed of carbon fiber and pulp to make paper. This kind of paper has uneven resistance and uneven dispersion of carbon fiber in the paper, resulting in uneven heat generation. Moreover, the paper is easy to break, has low fastness, and is...
