Abstract

The invention discloses a solar energy reflecting heat-insulation coating. The solar energy reflecting heat-insulation coating comprises, by weight, 2-3 parts of mesoporous silicon dioxide powder MCM-41 from Aladdin Industrial Corporation, 1-2 parts of nanoscale titanium dioxide, 16-17 parts of Dow solid epoxy resin DER671, 12-15 parts of stearalkonium hectorite, 3-4 parts of zinc stearate, 3-4 parts of calcium stearate, 1-2 parts of hydroxypropyl guar gum, 2-3 parts of hydroxypropyl methyl cellulose, 4-5 parts of potassium tripolyphosphate, 7-8 parts of butyl carbitol, 8-9 parts of calcium silicate, 6-7 parts of aluminium silicate, 11-12 parts of melamine formaldehyde resin powder, 1-2 parts of 2-amino phenyl mercaptan, 0.3-0.5 part of gamma-amino propyl triethoxysilane, 14-15 parts of methyl isobutyl ketone, 15-16 parts of toluene and 8-9 parts of xylene. The solar energy reflecting heat-insulation coating has the advantages of excellent heat-insulation effect, high reflective rate, and excellent acid-alkali resistance, salt-fog resistance and aging resistance.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to a solar reflective heat-insulating coating and a preparation method thereof. Background technique [0002] Architectural coatings have the functions of decoration, protection and habitability improvement. The proportions of various functions vary depending on the purpose of use. The decorative function is to improve the appearance value of a building by beautifying it. It mainly includes the conceptual design of flat color, pattern and gloss and the conceptual design of three-dimensional pattern. However, it must be matched with the shape of the building itself and the size and shape of the base material itself, so that it can be fully utilized. The protection function refers to the function of protecting the building from the influence and damage of the environment. Different types of protected objects have different requirements for protection functions. For example, th...
