Embodiment 1

[0030] Use the prepared pulp (selection of plant fibers, such as straw), add 3-6% by weight nano-carbon fiber 2 hours after the start of beating, and add 2-3% by weight of paper-making diffusing agent methylene bis-naphthalene sulfonic acid Sodium (NNO), continue beating for 1 hour and add nanometer far-infrared negative ion powder (bamboo carbon fiber) with a weight content of 2-3%, the pulp is the remainder, and pass the test after beating for 5 hours; The resistivity of the conductive paper in this embodiment is 40-800Ω·cm, which can be used as a carbon crystal electric heating plate for heating, such as floor heating panels, shed heating panels, electric heating panels, electric heaters, pedals, etc.

Embodiment 2

[0032] Others are identical with embodiment 1, only the weight content of the nano-carbon fiber that adds is increased to 6-10%, the weight content of nanometer far-infrared negative ion is increased to 3-5%, and papermaking diffusion agent sodium methylene bis-naphthalene sulfonate (NNO ) The weight content is increased to 3-5%, and the pulp is the balance. The resistivity of the conductive paper in this embodiment is 10-30Ω·cm, and the finished product can be used for antistatic and leakage current, electrical packaging, computer room, etc.

Embodiment 3

[0034] Others are the same as in Example 1, the weight content of carbon nanofibers is 10-20%, and the weight content of nano far-infrared negative ions is 3-5%. The weight content of the paper-making diffusing agent sodium methylene dimethyl naphthalene sulfonate (MF) is 3-5%, and the pulp is the balance. The resistivity of the conductive paper in this embodiment is 3-10Ω·cm, and the finished product can be used as a 1.5-36V low-voltage health care product and an electric heating product for daily necessities.

Abstract

The invention relates to technique for improving an electric heating element, in particular to nano far infrared negative ion carbon crystal conductive paper and a method for making the same. The conductive paper resolves the problems of the uneven heat generation, the existence of heat spot and the excessive temperature difference existing in prior electric heating products and is used for electric heating elements for anti-static electricity and making of heating electric hot plates. The conductive paper comprises the following components in percentage by weight: 70 to 96 percent of paper pulp, 2 to 20 percent of nano carbon fiber, 1 to 5 percent of nano far infrared negative ion powder and 1 to 5 percent of dispersing agent. In the invention, by using paper pulp, nano carbon fiber, nano far infrared negative ion powder and dispersing agent as materials and undergoing steps of pulping, pulp beating, pulp mixing, papermaking, drying and scrolling, etc., the conductive paper is made; in the process of pulp beating, the pulp mixing step is made; the pulp mixing step is as follows: nano carbon fiber and dispersing agent and nano far infrared negative ion powder are evenly added in the paper pulp. The invention possesses of functions of the emission of far infrared rays and the release of negative ions at the same time and can effectively and completely release electric charges, thereby having effects of purification and disinfection and making human bodies healthier.

Description

technical field [0001] The invention relates to an improvement technology of an electric heating element, in particular to a nanometer far-infrared anion carbon crystal conductive paper 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 paper are also developing rapidly. Although carbon fiber electric heating products have many advantages in their use, such as: stable electrical conductivity, high strength, small specific gravity, thin thickness, Ease of use etc. However, the common weakness of the existing carbon fiber conductive paper is that the heating products made of electric heating products have uneven heating, hot spots, and large temperature differences. National standards also bring hidden dangers to use. Although carbon fiber far-infrared enhanced conductive paper has appeared, not all of them are beneficial ...
