Problems solved by technology

However, for construction projects with better durability and thermal insulation effects, water-based acrylic coatings cannot meet the requirements.
However, the existing water-based thermal insulation coatings generally have a solar reflectance of about 0.8, a thick coating film, and poor stain resistance.

preparation example Construction

[0033] A kind of preparation method of water-based acrylic heat insulating paint of the present invention, comprises the following steps:

[0034] A. Dispersion: Stir 0.2-0.4 parts of the water-resistant dispersant SN-5027 and 5-8 parts of deionized water evenly, then add nano-silica split JY100, and use a high-speed disperser at a speed of 2000 rpm Disperse for 15-25 minutes to make nano-silica pre-dispersed slurry;

[0035] B. Homogeneously mixing and dispersing grinding: the remaining deionized water and water-resistant dispersant SN-5027, defoamer A-34, propylene glycol, titanium dioxide, calcium carbonate, thermal insulation powder S-20 and hollow glass microspheres VS5500 in sequence Add it into the mixing container and stir evenly, disperse at high speed and grind it to a fineness below 50μm through the grinding equipment;

[0036] C. Stirring detection: Add the nano-silica pre-dispersed slurry prepared in step A and the special emulsion for heat-insulating coating, fi...

Abstract

The invention discloses a water-borne acrylic thermal insulating coating and a preparation method thereof. The water-borne acrylic thermal insulating coating comprises the following components in parts by weight: 30-50 parts of special emulsion BTA-100 for the thermal insulating coating, 5-15 parts of hollow glass microsphere VS5500, 15-20 parts of titanium white, 5-10 parts of calcium carbonate, 5-10 parts of heat insulation powder S-20, 0.5-3.0 parts of nanometer silicon dioxide powder JY100, 0.1-0.5 part of deforming agent A-34, 0.5-1.0 part of water-resistant dispersing agent SN-5027, 0.5-2.0 parts of propylene glycol, 2.0-5.0 parts of film-forming agent Dalpad C, 0.5-1.0 part of thickening agent TT-935, 0.1-0.2 part of mildew-proof agent EPW, 0.1-0.2 part of bactericide MV and 15-40 parts of deionized water. The water-borne acrylic thermal insulating coating of the invention has excellent physicochemical performance, heat insulation reflection effect, the solar reflectance and the hemispherical emissivity of more than 0.89, and excellent stain resisting performance; meanwhile, the contents of VOC (Volatile Organic Compounds) and heavy metals are in line with the requirements of national compulsory standards for limit quantity.

Description

technical field [0001] The invention relates to a paint, in particular to a water-based acrylic heat-insulating paint. The present invention also relates to a preparation method of the above-mentioned water-based acrylic heat-insulating paint. Background technique [0002] Water-based acrylic paint (latex paint) is a decorative and protective coating for building exterior walls, which can meet the general coating requirements for building exterior walls, that is, better physical and chemical properties, and stain resistance ≤ 15%. However, for construction projects with better durability and thermal insulation effects, water-based acrylic coatings cannot meet the requirements. However, the existing water-based thermal insulation coatings generally have a solar reflectance of about 0.8, a relatively thick coating film, and poor stain resistance. Contents of the invention [0003] The present invention is completed in order to solve the deficiencies in the prior art. The p...
