Heat-absorbing material and preparation method thereof

Abstract

The invention belongs to the technical field of materials and particularly relates to a heat-absorbing material and a preparation method thereof. The heat-absorbing material is prepared from the following components: 4-8 parts of urea, 5-9 parts of borax, 30-55 parts of silicon nitride, 2.5-3.5 parts of carbon material, 14-16 parts of suspending agent, 15-25 parts of ammonium chloride, 3.2-7.3 parts of graphite powder, 9-12 parts of magnesium sulfate, 3-10 parts of acrylic water-absorbent resin, 5-14 parts of silica gel, 5.5-14.5 parts of molybdenum oxide, 1.6-13.5 parts of glass fiber, 13-22parts of polyvinyl alcohol, 6-13 parts of titanium dioxide, 6-12 parts of raw gypsum powder, 5-10 parts of hydroxypropyl guar gum, 7-15 parts of hydroxypropyl cellulose, 5-12 parts of coconut diethanolamide and 12-28 parts of hydroxypropyl distarch phosphate. The heat-absorbing material disclosed by the invention has the advantages of simple preparation method, strong applicability, long service life, recyclable utilization, strong heat-absorbing effect, good environmental friendliness, no harmful-gas volatilization in the heat-absorbing process, no corrosivity and good high-temperature resistance.

Description

technical field [0001] The invention belongs to the technical field of materials, and in particular relates to a heat-absorbing material and a manufacturing method thereof. Background technique [0002] With the continuous development of human society, the contradiction between man and nature has become more and more prominent. The most prominent problems facing the world at present are environment and energy, that is, environmental degradation and energy shortage. Faced with such a situation, the governments of various countries have adopted correct countermeasures to deal with it, and the most effective method is to develop new materials and corresponding technologies. In fact, people have shown positive and effective effects on the development and utilization of solar heat absorbing materials in the past few years. The development of this new functional material can not only solve the energy shortage faced by human beings, but also not cause environmental pollution. Al...
