Abstract

The invention provides nano heat-insulation paint, a preparation method of a heat-insulation coating and heat-insulation glass. The nano heat-insulation paint is prepared from, by weight, 6.7-30% of nano powder, 55-78% of high-polymer resin and 15-20.3% of paint auxiliaries. The nano powder comprises, by weight, 33.5-70% of nano silicon nitride and 30-66.5% of silver. The preparation method of the heat-insulation coating includes the step that on the basis of a processing technology of the nano heat-insulation paint, after a curing agent is added and evenly stirred, the mixture is quickly coated on a substrate, heating and curing are conducted, and the nano heat-insulation coating is obtained. The heat-insulation glass comprises a glass substrate and the nano heat-insulation coating attached to the glass substrate. Photo-thermal radiometry and ultraviolet light can be effectively isolated. Compared with traditional heat-insulation glass, the heat insulation performance of the glass can be obviously improved, the application range is wide, the hardness and flexibility of the coating can be adjusted according to the ratio of the paint, and operation is convenient.

Description

technical field [0001] The invention relates to glass heat insulation technology, in particular to a nano heat insulation coating, a preparation method of the heat insulation coating and heat insulation glass. Background technique [0002] Thermal insulation coating refers to a kind of functional coating developed in recent years, which reflects heat and light, has short construction period and quick effect. There are three main types of thermal insulation paint from the principle of characteristics, insulating conductive thermal insulation coatings, reflective thermal insulation coatings and radiation thermal insulation coatings. [0003] Barrier-type heat-insulating coating is a kind of coating that realizes heat insulation through the high thermal resistance of the coating itself, and it belongs to thick-film coating. The coating is applied to a certain thickness during construction, generally 5-20mm. After being fully dried and cured, the thermal conductivity of the mat...
