preparation example Construction

[0026] The preparation method of above-mentioned anti-electromagnetic radiation glue is characterized in that, comprises the following steps:

[0027] Step 1: Weigh the following components according to mass percentage: epoxy resin 20%-50%, conductive carbon powder 10%-20%, graphite 5%-10%, tourmaline 10%-20%, copper powder 5% %~10%, nickel powder 5%~10%, dicyandiamide 1%~3%, magnesium hydroxide 9%~12%, the sum of the mass percentages of the above components is 100%;

Embodiment 1

[0036] Step 1: Weigh the following components respectively: 20g of epoxy resin (E20), 20g of conductive carbon powder, 10g of graphite, 20g of tourmaline, 10g of copper powder, 10g of nickel powder, 1g of dicyandiamide, and 9g of magnesium hydroxide;

[0037] Step 2: Add the epoxy resin and curing agent weighed in step 1 into the reactor, and add acetone with a total mass of each component of 100% to dissolve, and then add conductive carbon powder, tourmaline, and magnesium hydroxide to the reactor in turn , and add graphite, copper powder, nickel powder, stir evenly, use sm-12 type coating machine to coat the surface of carbon crystal electronic heating plate, the thickness of coating is more than 10μm, and then solidify at 150℃ for 2h to form Electromagnetic radiation shielding and adsorption layer.

[0038] After adding the anti-electromagnetic radiation coating, the electromagnetic radiation can be reduced to 0.8 μΤ.

Embodiment 2

[0040] Step 1: Weigh the following components respectively: 50g of epoxy resin (E51), 10g of conductive carbon powder, 5g of graphite, 10g of tourmaline, 5g of copper powder, 5g of nickel powder, 3g of dicyandiamide, and 12g of magnesium hydroxide;

[0041] Step 2: Add the epoxy resin and curing agent weighed in step 1 into the reactor, and add acetone with a total mass of 200% of each component to dissolve, and then add conductive carbon powder, tourmaline, and magnesium hydroxide to the reactor in turn , and add graphite, copper powder, nickel powder, stir evenly, use sm-12 type coater to coat the surface of carbon fiber electronic heating plate, the thickness of the coating is more than 15μm, and then cure at 180°C for 0.5h to form Electromagnetic radiation shielding and adsorption layer.

[0042] After adding the anti-electromagnetic radiation coating, the electromagnetic radiation can be reduced to 0.73 μΤ.

Abstract

The invention discloses anti-electromagnetic radiation glue used for carbon crystal and carbon fiber electronic heaters. The anti-electromagnetic radiation glue comprises the following components in percentage by weight: 20-50% of epoxy resin,10-20% of conductive carbon powder, 5-10% of graphite, 10-20% of tourmaline, 5-10% of copper powder, 5-10% of nickel powder, 1-3% of a curing agent and 9-12% of magnesium hydroxide, and the sum of the weight percentage of each component is 100%. The preparation method is as follows: epoxy resin and dicyandiamide are dissolved, conductive carbon powder, tourmaline and magnesium hydroxide are added sequentially, graphite, copper powder and nickel powder are added, even stirring is performed, the surface of an electronic heating plates is coated with the glue, and the glue is cured to form an electromagnetic radiation shield and absorption layer. The glue solves the problem that the present carbon crystal and carbon fiber electronic heaters generate electromagnetic radiation which harms human health in the use process, the cost is low, the shield is tight, the absorbability is strong, and the glue can reduce electromagnetic radiation to be lower than the stand of 100muT and within a lower range.

Description

technical field [0001] The invention belongs to the technical field of carbon crystal and carbon fiber electronic heaters, and relates to an anti-electromagnetic radiation glue used for carbon crystal and carbon fiber electronic heating plates, and also relates to a preparation method of the anti-electromagnetic radiation glue. Background technique [0002] The existing carbon crystal and carbon fiber electronic heating panels are currently not treated with anti-electromagnetic radiation. Therefore, in the floor heating and heating products produced, electromagnetic radiation will be generated when energized and used, and electromagnetic radiation is harmful to the human body and endangers the human body. healthy. Contents of the invention [0003] The purpose of the present invention is to provide an anti-electromagnetic radiation glue for carbon crystal and carbon fiber electronic heating boards, which solves the problem that the existing carbon crystal and carbon fiber ...
