Abstract

The invention discloses a radiation type epoxy polyurethane energy-saving coating which is prepared from the following raw materials in parts by weight: 30-60 parts of polyurethane emulsion, 20-30 parts of oligomeric waterborne epoxy resin, 5-10 parts of radiation filler, 1-3 parts of modifying agent, 0.01-0.05 part of graphene oxide, 0.2-0.5 part of photocuring agent and 2-5 parts of auxiliaries.In the energy-saving coating, the radiation filler is specifically modified; the compatibility of raw materials is higher; the added graphene oxide material is capable of increasing the heat conduction rate of radiation filler, increasing the thermal emission efficiency of radiation filler and obviously promoting the cooling heat-insulating effect and mechanical properties of the energy-saving coating.

Description

technical field [0001] The invention relates to the field of energy-saving materials, in particular to a radiation-type epoxy polyurethane energy-saving coating. Background technique [0002] With the rapid development of social economy, energy consumption is increasing day by day, and most of the existing energy sources are non-renewable energy sources, which will lead to more and more serious problems of energy shortage. Therefore, vigorously develop energy-saving materials to slow down the speed of energy consumption and maintain The rapid and sustainable development of the economy becomes necessary. Due to the huge amount of energy consumed due to the energy loss of buildings, people have paid more and more attention to building energy conservation in recent years. Architectural coatings are an important building material, and the promotion of energy-saving functional coatings is of great significance to saving resources and promoting sustainable social and economic dev...
