Example Embodiment
[0037] Based on the structure of the graphene layered composite floor heating board, the present invention also provides a method for preparing the graphene layered composite floor heating board, which includes the following steps:
[0038] S1. Preparation of graphene electric heating filler;
[0039] S2. Preparation of graphene electric heating paint;
[0040] S3. Coating of graphene electric heating paint;
[0041] S4. Assembly of layered composite floor heating panels.
[0042] Since the graphene electrothermal filler used in the present invention is an electrothermal coating, the conductive filler with high conductivity is mainly used to improve the conductivity of the coating. A small amount of palladium powder is added to the electrothermal coating of the present invention to improve the conductivity of the electrothermal coating , Far due to the electrothermal coating composed of a single graphene filler. Preferably, the graphene electric heating filler is a mixture of modified...
Example Embodiment
[0055] Example 1
[0056] Step 1. Preparation of graphene electric heating filler: Dissolve 1Kg graphene powder (N008-P) and 0.1Kg dispersant in a saturated ferric chloride solution, react at high temperature for 3 hours under nitrogen protection, and finally soak The iron oxide nanoparticles are removed in dilute hydrochloric acid, washed with water to neutrality, and dried for use; the graphene electric heating filler is a mixture of modified graphene and palladium powder in a mass ratio of 10:1.4.
[0057] Step 2. Preparation of graphene electric heating paint: Weigh the water-based acrylic resin and deionized water in a mass ratio of 1:1.6, add them to a beaker and mix well and stir until completely dissolved to form a water-based acrylic resin emulsion; take a certain amount according to the ratio Add the water-based acrylic resin emulsion to the beaker, while mechanically stirring, slowly add a certain amount of dispersant and defoamer additives, and finally add the graphene ...
