Problems solved by technology

[0004] Chinese patent CN101603619B discloses a method for making a transparent barrier. The heat-resistant layer prepared by it contains antimony tin oxide, indium tin oxide and tungsten oxide. Although it has a good heat insulation effect, the process is complicated and difficult to realize industrialization; A method for making an intelligent light-controlled heat-insulating film is proposed. The heat-resistant layer contains benzopyran, tin dioxide, tungsten trioxide and antimony dioxide. However, too many layers lead to high cost and it is difficult to realize industrialization. ; Chinese patent CN109071867A discloses a preparation method of an infrared barrier composition, and the prepared indium tin oxide, antimony tin oxide, tin oxyfluoride and tungsten trioxide are multilayer structures, but the infrared heat insulation function is not ideal

Abstract

The invention discloses an infrared barrier composition, and the composition is prepared from an inorganic chlorinated mixture, a solvent and a dispersing agent, wherein the inorganic chlorinated mixture comprises the following components in percentage by mass: 20-60% of tungsten tetrachloride, 30-50% of titanium tetrachloride and 10-30% of tin tetrachloride; the mass ratio of the solvent to the inorganic chlorination mixture is 1: 2; the addition amount of the dispersing agent is 1-3wt% of the weight percentage of the inorganic chlorinated mixture; the solvent is absolute ethyl alcohol, propyl alcohol, isopropanol or n-butyl alcohol, and the dispersing agent is sodium dodecyl sulfate, sodium dodecyl benzene sulfonate, sodium hexadecyl sulfonate or sodium hexadecyl benzene sulfonate. The composition can be widely applied to the fields of heat insulation films, coatings, printing ink, glass laminated films and the like. In addition, the invention also discloses a preparation method of the infrared barrier composition.

Description

technical field [0001] The invention relates to an infrared shielding composition, and furthermore, the invention also relates to a preparation method of the infrared shielding composition. Background technique [0002] As the earth's resources and energy are increasingly scarce, energy conservation and environmental protection have become a top priority for all countries. The rapid development of the construction industry and the automobile industry has aggravated the task of energy conservation and emission reduction. Research and development of thermal insulation compositions that can block infrared rays is one of the current key scientific research projects in my country. [0003] Many inorganic substances have the function of blocking infrared rays, and also have the characteristics of good weather resistance, good chemical stability and high temperature resistance. Inorganic chlorides have a certain infrared reflection function, and the infrared blocking effect of in...
