Embodiment 1

[0035] Water-based polyacrylate is used as the polymer material, and its mass percentage ratio is as follows:

[0036]

[0037] After modifying the above powder, use a high-speed mixer to mix evenly, and then add it to the water-based polymer coating. During the addition process, keep stirring at a high speed, and the stirring temperature is 50°C. After all the powders are uniformly dispersed, add the solubilizer and defoamer and continue stirring for 30 minutes.

[0038] Adding a defoamer during the stirring process helps to prevent the generation of air bubbles in the composite material, so that pores appear during the coating process, which affects the infrared radiation performance and thermal conductivity of the product. The far-infrared composite material prepared by this method is evenly coated on a dust-free and flat non-woven fabric carrier with a thickness of 1 μm. The coated product was dried in a vacuum oven at a drying temperature of 100° C. and a drying time ...

Embodiment 2

[0040] Water-based polyurethane is used as the polymer material, and its mass percentage ratio is as follows:

[0041]

[0042] After modifying the above powder, use a high-speed mixer to mix evenly, and then add it to the water-based polymer coating. During the addition process, keep stirring at a high speed, and the stirring temperature is 40°C. After all the powders are dispersed evenly, add the solubilizer and defoamer and continue stirring for 40 minutes.

[0043] Adding a defoamer during the stirring process helps to prevent the generation of air bubbles in the composite material, so that pores appear during the coating process, which affects the infrared radiation performance and thermal conductivity of the product. The far-infrared composite material prepared by this method is uniformly coated on a dust-free flat gauze carrier with a thickness of 1 μm. The prepared samples were dried in a vacuum oven at 120°C for 5 min to obtain the final samples. When the tempera...

Abstract

The invention relates to a high-efficiency and high-strength composite material with far infrared radiation heating. The material is characterized in that the material comprises the following raw materials in percentages by mass: 1-10% of graphene, 5-10% of graphite, 5-10% of nanocarbon, 1-2% of tourmalinite, 0.3-2% of a thickening agent, 0.01-0.05% of an antifoaming agent, and the balance being an aqueous high-molecular material. The far infrared composite material comprises graphene, graphite, nanocarbon, tourmalinite, and other powder materials with the far infrared radiation heating function. The material can be widely applied to electric heating, electric heating drying, health care, antibiosis, and other aspects. In addition, the composite material comprises the special tourmalinite material, in order to release a certain concentration of negative oxygen ions, and realize the purpose of air purification and environmental protection.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of far-infrared radiation heating composite materials, in particular to a high-efficiency and high-strength far-infrared radiation heating composite material and a preparation method thereof. [0003] 【Background technique】 [0004] The 21st century is an era that advocates energy conservation, health and environmental protection. The research and development of high-efficiency and high-strength far-infrared heating composite materials actively responds to the development of new materials in the 21st century, breaking through the heat transfer methods of traditional heating materials. Improve the material on the heat path, and open up an energy-saving and environmentally friendly radiation heating technology. [0005] There are three main ways of heat transfer: heat conduction, heat convection and heat radiation. The traditional heating method is mainly heat convection, but for this heating method, ...
