Abstract

The invention discloses a composition of a reflecting thermal insulating coating and a production method of the composition. The composition is prepared from the following components in parts by weight: 25-35 parts of elastic emulsion, 15-25 parts of organic silicon emulsion, 5-13 parts of polyacrylamide, 2-9 parts of titanium dioxide, 5-18 parts of cenosphere, 1-6 parts of a coalescing agent, 2-7 parts of a defoamer, 3-9 parts of a pH regulator, 4-12 parts of a thickening agent, 2-10 parts of a flatting agent and 30-40 parts of deionized water. The prepared composition of the reflecting thermal insulating coating is high in solar light reflection rate and coating emissivity, good in reflecting thermal insulating effect, good in coating weather fastness, and long in service life. The production method is simple and suitable for industrial production; the energy consumption and the cost are reduced.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a composition of a reflective heat-insulating coating and a preparation method thereof. Background technique [0002] In order to reduce the increase of the internal temperature of the building caused by the external environment, the traditional method is to consider the reduction of the heat transfer rate, and use a thermal insulation material with a small heat transfer coefficient to reduce the heat transfer from heat sources such as solar energy to the building. This type of traditional thermal insulation material is mainly to increase the gas phase porosity, reduce the thermal conductivity and conduct heat transfer. In order to reduce convective heat transfer and radiation heat transfer in the use environment, fiber-based insulation materials must have a thicker coating; profile-type stepless insulation materials must be assembled and constructed, and there are many seams, which affec...
