Embodiment 1

[0018] A method for preparing stone-like paint for heat insulation and heat preservation of interior and exterior walls, comprising the following steps:

[0019] S1. Ingredients: 257 parts of water, 4 parts of dispersant, 1 part of wetting agent, 3 parts of fungicide, 2 parts of inorganic thickener, 1.5 parts of multifunctional additive, 2.5 parts of defoamer, 50 parts of infrared reflective pigment, 175 parts of rutile titanium dioxide, 75 parts of precipitated barium sulfate, 380 parts of silicon acrylic emulsion, 20 parts of propylene glycol, 24 parts of film-forming aid, and 2 parts of thickener;

[0020] S2. Base material mixing: add 200 parts of water, 4 parts of dispersant, 1 part of wetting agent, 1 part of bactericide, 2 parts of inorganic thickener, 1.5 parts of multifunctional additive, and 1.5 parts of defoamer into the mixing tank in sequence In, then utilize a stirring mechanism to stir and mix the base material in the mixing tank, and the mixing time is 5 minute...

Embodiment 2

[0029] Prepare two templates A and B of the same color, use common paint on the surface of A to paint, use the paint prepared by the present invention on the surface of B to paint, and use a temperature difference tester to irradiate, wherein the temperature difference tester is Heng The SMAI temperature difference tester detects the holding temperature of two samples every 6 minutes, a total of ten times, and the obtained data are shown in the following table:

[0030] 6min 12min 18min 24min 30min 36min 42min 48min 54min 60min A board 78℃ 93℃ 93℃ 94℃ 103℃ 103℃ 103℃ 106℃ 105℃ 108℃ B board 73℃ 82℃ 82℃ 85℃ 92℃ 92℃ 96℃ 98℃ 98℃ 98℃

[0031] As can be seen from the above table, at the same time and under the same irradiation conditions, compared with the common coatings, the coatings prepared by the invention have gentler temperature changes, high reflectivity, and the effect of reflection and heat insulation. Therefore,...

Abstract

The invention discloses a preparation method of stone-like paint for heat insulation of interior and exterior walls. The method comprises the following steps: S1, burdening 257 parts of water, 4 partsof a dispersant, 1 part of a wetting agent, 3 parts of a sterilizing agent, 2 parts of an inorganic thickener, 1.5 parts of a multifunctional auxiliary agent, 2.5 parts of an antifoaming agent, 50 parts of an infrared reflection pigment, 175 parts of rutile titanium dioxide, 75 parts of precipitated barium sulfate, 380 parts of a silicone acrylic emulsion, 20 parts of propylene glycol, 24 parts of a coalescing agent and 2 parts of a thickener; and S2, mixing base materials: sequentially adding 200 parts of water, 4 parts of the dispersant, 1 part of the wetting agent, 1 part of the sterilizing agent, 2 parts of the inorganic thickener, 1.5 parts of the multifunctional auxiliary agent and 1.5 parts of the antifoaming agent into a mixing tank, and then stirring and mixing the base materialsin the mixing tank through a stirring mechanism. By selecting the infrared reflection pigment, the reflectivity of a coating layer to sunlight can be improved, the reflection and heat insulation effects are achieved, the internal temperature of a building is reduced, and the effects of heat insulation and heat preservation are achieved.

Description

technical field [0001] The invention relates to the technical field related to paint production, in particular to a method for preparing stone-like paint for heat insulation and heat preservation of interior and exterior walls. Background technique [0002] With the development of social and economic level and the continuous improvement of people's living conditions, the demand for energy is also increasing. The reserves of traditional energy such as coal, oil, and natural gas are limited, and the shortage of oil in particular threatens the energy security of the entire human society. Therefore, while exploring new energy sources, countries urgently need to improve energy utilization efficiency and reduce energy consumption. In summer in hot areas, the outer walls of civil buildings receive strong radiation from the sun, causing the surface temperature to rise, which can reach 40-50 degrees, and the surface temperature of metal objects can reach 70-80 degrees. An increase ...
