Solar fireproof heat-absorbing paint

Abstract

The invention discloses a solar fireproof heat-absorbing paint. The solar fireproof heat-absorbing paint comprises the following materials of: silicone acrylic emulsion, modified sulfonated graphene, yttria-stabilized zirconia powder, SiC powder, ultrafine iron powder, silica sol, deionized water, a leveling agent, a lubricant, chlorinated rubber, vinyl chloride resin, melamine, glycol ether, a flame retardant and a plasticizing agent. The solar fireproof heat-absorbing paint is prepared by pulping solid powdery materials and liquid materials for 90-120 minutes on a grinding machine and then uniformly mixing. The solar fireproof heat-absorbing paint disclosed by the invention has the advantages that (1) the preparation cost of the modified sulfonated graphene is low, the method is simple, the used materials are environmental-friendly, no traditional toxic (hydrazine) or expensive (sodium borohydride) reduction reagents are used; (2) due to use of the sulfonated graphene in the paint, the heat absorbing efficiency of a finished solar battery plate coating is greatly improved; and (3) the paint is high in expansion coefficient, is smokeless and non-toxic, is strong in adhesive force and has excellent fireproof and oil-resistant properties.

Description

technical field [0001] The invention relates to the field of solar energy, in particular to a solar fire-resistant and heat-absorbing paint. Background technique [0002] Solar energy (solar energy) refers to the thermal radiation energy of the sun (see the three ways of thermal energy transmission: radiation), and its main manifestation is the sun's rays that are often said. In modern times, it is generally used to generate electricity or provide energy for water heaters. Since the birth of life on earth, it has mainly survived on the heat radiation energy provided by the sun. Since ancient times, humans have also known to use sunlight to dry objects and use it as a method of making food, such as making salt and drying salted fish. With fossil fuels decreasing day by day, solar energy has become an important part of the energy used by human beings and has been continuously developed. There are two ways to use solar energy: photothermal conversion and photoelectric convers...

Problems solved by technology

Among them, graphene, especially sulfonated graphene, has excellent thermal conductivity. The sulfonation treatment of carbon materials plays an important role in improving its performance and application range. However, the traditional method is complicated, and most of them require special conditions or toxic reduction. Reagents are difficult to achieve industrialization and have caused great pollution to the environment, so how to prepare high-quality sulfonated graphene simply, cheaply and environmentally friendly is one of the difficulties to be overcome at present; at the same time, due to the long-term exposure of solar panels, they have Good fire resistance is also a must
