Heat-insulating antibacterial nano-coating and a preparation method thereof

Abstract

The invention relates to the technical field of coatings, in particular to a heat-insulating antibacterial nano-coating and a preparation method thereof. The heat-insulating antibacterial nano-coatingis prepared from the following raw materials in parts by weight: 50-60 parts of pure acrylic emulsion, 50-60 parts of odorless emulsion, 0.3-0.5 parts of a dispersing agent, 4-6 parts of an adhesionpromoter, 5-8 parts of a film forming agent, 8-14 parts of filler, 0.3-0.7 parts of an antifoaming agent, 4-5 parts of hollow microspheres, 15-25 parts of nano silver oxide and 18-20 parts of deionized water. The heat-insulating antibacterial nano-coating has better reflection, heat insulation and sterilization effects, and also has good rigidity, heat resistance and extensibility.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a nano heat-insulating antibacterial coating and a preparation method thereof. Background technique [0002] With the worldwide energy shortage and environmental problems brought about by energy utilization, people are facing two major problems of energy depletion and environmental degradation. In addition to the efficient conversion of energy and the reasonable development of renewable energy, energy saving and consumption reduction are the An effective way for sustainable economic development. Statistics show that building energy consumption accounts for 35%-45% of social energy consumption. Among them, air conditioning and heating energy consumption account for 55%-65% of building energy consumption. In recent years, my country's construction industry has developed rapidly. However, most buildings in my country have poor thermal insulation performance. Compared with other count...

Problems solved by technology

[0005] However, in the past, heat-insulating coatings have single performance, poor heat-insulating effect, and complicated process conditions, which are not conducive to large-scale promotion to the market, and the heat-insulating coatings used now achieve the purpose of heat insulation through their own high thermal resistance. Belonging to thick film coating, this kind of coating has certain defects, such as the coating shrinks greatly during the drying process, the adhesion is low, and the heat insulation efficiency is low.
