preparation example Construction

[0055] A preparation method of water-based wall paint, comprising the steps of:

[0056]Step 1: According to parts by weight, weigh silicon-acrylic emulsion, titanium dioxide, cordierite, nano-zirconia, hollow glass microspheres, talcum powder, sericite powder, water glass, ultraviolet absorber, film-forming aid, dispersant, Wetting agent, defoamer, leveling agent, thickener, antifungal agent, water, magnesium hydroxide;

[0057] Step 2: Add titanium dioxide, cordierite, nano zirconia, hollow glass microspheres, talcum powder, sericite powder, water glass, ultraviolet absorber, dispersant, wetting agent, half weight of defoamer, anti Mold agent and magnesium hydroxide, stir evenly;

[0058] Step 3: Add silicone-acrylic emulsion, film-forming aid, the other half of the weight of defoamer and leveling agent, and stir evenly;

[0059] Step 4: Add thickener, stir evenly and discharge.

Embodiment 3

[0092] The thermal insulation performance of Example 3 is better than that of Comparative Examples 2 and 3, and the thermal insulation performance of Comparative Example 4 is worse than that of Comparative Examples 2 and 3. It can be seen that both cordierite and nano-zirconia can improve the thermal insulation performance of the present invention. In addition, the joint addition of cordierite and nano-zirconia can improve the thermal insulation performance of the present invention more than the sum of the improvement effects of cordierite and nano-zirconia alone on the thermal insulation performance of the present invention. Therefore, cordierite and nano-zirconia can produce a synergistic effect in the present invention and promote the improvement of the thermal insulation performance of the present invention.

[0093] The weather resistance and flame retardancy of Example 3 are similar to those of Comparative Examples 2 and 3, and the weather resistance and flame retardancy...

Abstract

The invention discloses a water-based wall coating and a preparation method thereof. The water-based wall coating comprises the following components in parts by weight: 30-40 parts of silicon-acrylicemulsion, 15-25 parts of titanium dioxide, 20-30 parts of cordierite, 10-15 parts of nano zirconia, 5-15 parts of hollow glass beads, 2-4 parts of talcum powder, 2-4 parts of sericite powder, 10-15 parts of water glass, 0.5-1 part of an ultraviolet absorbent, 0.5-1 part of a film forming aid, 0.5-1 part of a dispersing agent, 0.5-1 part of a wetting agent, 0.1-0.5 part of a defoaming agent, 0.5-1part of a leveling agent, 3-5 parts of a thickening agent, 0.1-0.3 part of a mildew preventive and 15-20 parts of water. The water-based wall coating has the beneficial effects that the water-based wall coating has excellent heat preservation performance, the external heat preservation of outer walls is realized, and the energy consumption is reduced.

Description

technical field [0001] The invention relates to a wall paint, in particular to a water-based wall paint and a preparation method thereof. Background technique [0002] Wall coating refers to the coating used to decorate and protect the building wall, making the building wall beautiful and tidy, and at the same time protecting the building wall and prolonging its service life. According to the classification of building walls, wall coatings include interior wall coatings and exterior wall coatings. Interior wall coatings focus on decoration and environmental protection; exterior wall coatings focus on protection and durability. [0003] The Chinese patent with publication number CN105400352A discloses a high weather resistance water-based wall coating and a preparation method thereof. The water-based wall paint consists of the following components in parts by weight: 30-38 parts of pure acrylic emulsion, 18-24 parts of PEVE emulsion, 8-10 parts of CPVC, 4-6 parts of pigment...
