Abstract

The invention relates to a preparation method for a heat-insulating coating of an external wall and belongs to the technical field of coating preparation. The preparation method comprises the following steps: taking rice straws as raw material; smashing the rice straws and performing steam explosion treatment; blending exploded fiber and complex enzyme for enzymolysis; performing oxidation and alkali treatment on enzymatic hydrolysate, thereby acquiring a reaction product and standing by; reacting sodium silicate solution with hydrochloric acid, thereby acquiring a reaction liquor; mixing coating emulsion with standby reaction product and reaction liquor, and then adding other auxiliary materials; quickly stirring and reacting, and then rising temperature and reacting, thereby acquiring the heat-insulating coating of the external wall. The heat-insulating coating of the external wall prepared according to the invention has an excellent heat-insulating property, is difficult to pulverize, is high in later strength and has a bright application prospect.

Description

technical field [0001] The invention relates to a preparation method of an exterior wall thermal insulation coating, which belongs to the technical field of coating preparation. Background technique [0002] Today, energy competition is becoming increasingly fierce, and energy issues have become a bottleneck restricting my country's economic development. In order to effectively alleviate energy problems, energy conservation and consumption reduction have been paid more attention to. The use of thermal insulation materials and thermal insulation coatings is one of the important measures for energy conservation. Energy is the premise and foundation for the survival and development of human society, and it provides the driving force for economic development. With the progress and development of science and technology, the contradiction between the increase of energy demand and the relative decrease of energy supply in human society is becoming more and more serious. At present...
