Nanometer heat-insulation paint

Abstract

Disclosed nanometer heat-insulation paint comprises the following compositions in parts by weight: 100 parts of UV varnish, 175-200 parts of a nanometer ceramic powder liquid, 5-15 parts of a suspension dispersion liquid, 0-50 parts of a diluent, 5-10 parts of a liquid-crystal mixing agent, and 0-5 parts of an initiator. The paint is low in solidification temperature requirement, rapid in solidification speed, and finishes solidification at 110 DEG C within 1 min. The energy consumption during solidification is low, and the UV solidification energy requirement is 100-110 MJ / m<2> and can be realized by using an ultraviolet lamp with the power of 120 W. By utilizing a cholesterol liquid crystal particle to reflect infrared ray and ultraviolet ray, a conventional technology of utilizing a heat-insulation material to slow a hot fluid is replaced, the coating thickness is relatively thin, the heat insulation effect is relatively obvious, and the heat insulation effect can reach 96% or more. The paint is added with the nanometer ceramic powder liquid prepared by diluting a nanometer ceramic powder, so that the hardness of the coating is substantially improved, the hardness is measured to be 4 H, and the service life is greatly prolonged.

Description

technical field [0001] The invention relates to the technical field of coatings, and discloses a nano heat-insulating coating. Background technique [0002] Heat insulation coating is a functional coating developed in recent years with heat insulation, sun protection, energy saving, environmental protection, simple construction, short construction period and quick effect. At present, most of the heat insulation coatings used are insulation coatings, which are a kind of coating that achieves heat insulation through the high thermal resistance of the coating itself. The moisture absorption rate is high, the bonding strength to the wall is low, and the decoration needs to be further improved. [0003] At the same time, the effective heat insulation efficiency of existing heat insulation coatings on the market is generally lower than 70%.
