Embodiment 1

[0030] see Figure 1-2 , the invention provides a kind of heat-insulating waterproof paint for building, is made up of each component of following weight fraction:

[0031] 40 parts of silicone acrylic emulsion, 30 parts of filler, 35 parts of water liquid, 1 part of vermiculite powder, 2 parts of anti-seepage barrier agent, 1 part of dispersant, 0.5 parts of defoamer, 2 parts of thickener, 10 parts of reflective heat insulation powder , 8 parts of heat-insulating and waterproof powder, 1 part of plasticizer and 2 parts of glass fiber. In the actual implementation, when selecting materials, a neutral silicone acrylic emulsion with a pH value of 7 should be selected, and the silicone acrylic emulsion has a bonding effect , the water plays a role of dilution, and the anti-seepage barrier has the function of temperature and water barrier. The plasticizer can make the prepared heat-insulating and waterproof coating not easy to crack when it is painted and formed into a film. The a...

Embodiment 2

[0043] see Figure 1-2 , the invention provides a kind of heat-insulating waterproof paint for building, is made up of each component of following weight fraction:

[0044] 50 parts of silicone acrylic emulsion, 40 parts of filler, 40 parts of water liquid, 2 parts of vermiculite powder, 5 parts of anti-seepage barrier agent, 2 parts of dispersant, 1 part of defoamer, 3 parts of thickener, 12 parts of reflective heat insulation powder , 9 parts of heat-insulating and waterproof powder, 1.5 parts of plasticizer and 3.5 parts of glass fiber. In the actual implementation, when selecting materials, a neutral silicone acrylic emulsion with a pH value of 7 should be selected, and the silicone acrylic emulsion has a bonding effect , the water plays a role of dilution, and the anti-seepage barrier has the function of temperature and water barrier. The plasticizer can make the prepared heat-insulating and waterproof coating not easy to crack when it is painted and formed into a film. T...

Embodiment 3

[0056] see Figure 1-2 , the invention provides a kind of heat-insulating waterproof paint for building, is made up of each component of following weight fraction:

[0057] Silicone acrylic emulsion 60 parts, filler 50 parts, water liquid 45 parts, vermiculite powder 3 parts, anti-seepage barrier agent 8 parts, dispersant 3 parts, defoamer 1.5 parts, thickener 4 parts, reflective heat insulation powder 14 parts , 10 parts of heat-insulating and waterproof powder, 2 parts of plasticizer and 5 parts of glass fiber.

Abstract

The invention provides a heat-insulating waterproof coating for a building and a preparation method thereof, and belongs to the technical field of building coatings. The heat-insulating waterproof coating for the building is prepared from the following components in parts by weight: 40-60 parts of silicone acrylic emulsion, 30-50 parts of filler, 35-45 parts of water liquid, 1-3 parts of vermiculite powder, 2-8 parts of an anti-seepage blocking agent, 1-3 parts of a dispersing agent and 0.5-1.5 parts of a de-foaming agent. The heat-insulating waterproof coating prepared from the silicone acrylic emulsion and the plasticizer has good bonding and film forming effects, the cracking possibility of the heat-insulating and waterproof coating in extremely cold weather is reduced, the heat-insulating waterproof coating also has a waterproof effect in extremely cold weather, by adding the anti-seepage blocking agent, the reflective heat-insulating powder, the heat-insulating waterproof powder and the glass fiber, the heat-insulating waterproof effect of the heat-insulating waterproof coating can be further improved, so that the waterproof heat-insulating performance of the heat-insulating waterproof coating is better than that of a common coating.

Description

technical field [0001] The invention relates to the field of architectural coatings, in particular to a heat-insulating and waterproof coating for architectural use and a preparation method thereof. Background technique [0002] Paint is a material that can be well bonded to the base material and form a complete and tough protective film on the surface of an object, called architectural paint. The role of coatings can be summarized into three aspects: protection, decoration, and special functions. The general composition of coatings: including film-forming substances, pigments and fillers, solvents, and additives. [0003] Existing architectural coatings have poor heat insulation and waterproof effects, which are not conducive to use. Moreover, in extremely cold weather, the coatings will crack due to poor adhesion, which will also affect the waterproofing effect of the coatings. Contents of the invention [0004] In order to make up for the above deficiencies, the prese...
