Problems solved by technology

[0005] The current solar heat-absorbing coatings are full of researches specifically aimed at the weather resistance and water resistance of solar energy coatings. Nowadays, nano-materials are used as raw materials for heat-absorbing materials, which can improve the weather resistance and heat-absorbing efficiency of coatings. For example, Chinese patent CN102286243A , but the cost is extremely high; there are also changes in the formulation of pigments to improve the weather resistance of the prepared coatings, such as Chinese patent CN102134428B, but its preparation process is complicated and requires high

Abstract

The invention relates to a coating, in particular to a solar heat absorption coating. The solar heat absorption coating is prepared from, by weight, 50-100 parts of film forming agent, 35-55 parts of light absorption agent, 10-30 parts of film forming assistant, 20-50 parts of solvent and 10-30 parts of assistant. The film forming agent is modified casein-gelatin. The solar heat absorption coating is characterized in that after the light absorption agent, the film forming agent, the solvent and the assistant are evenly dispersed through ball milling, the film forming assistant is added and evenly mixed, and then the solar heat absorption coating can be obtained. The film forming agent can be modified to serve as an important raw material for preparing the coating, the prepared coating has good weather fastness and waterproofness under the outdoor condition, the preparation process is simple and easy to understand, the heat absorption efficiency of the heat absorption coating can be guaranteed, and high promotional value is achieved.

Description

technical field [0001] The invention relates to heat-absorbing materials, in particular to a solar heat-absorbing paint. Background technique [0002] Energy utilization plays a pivotal role in the development of human society, but the excessive development of resources and inefficient resource utilization make human beings face a severe test. As we all know, solar energy is the most abundant and widely available renewable energy, which plays a major role in solving energy crisis and environmental problems. , making it a hot research topic in various countries. Our country is rich in solar energy resources and has broad prospects for solar energy utilization. At present, it is the first user and producer of solar water heaters in the world. [0003] Solar thermal application is one of the simplest, most direct, and most effective ways for human beings to utilize solar energy. However, due to the small and discontinuous energy density of solar energy after reaching the eart...
