preparation example Construction

[0036] Correspondingly, the embodiment of the present invention also provides a preparation method of the above-mentioned polyurea waterproof coating. This preparation method comprises the steps:

[0037] Step S01: Obtain each component according to the components and quantities in the polyurea waterproof coating;

[0038] Step S02: performing the first mixing treatment on polyaspartate polyurea resin, anti-sedimentation agent, titanium dioxide, and dispersant to obtain a mixed material;

[0039] Step S03: adding talcum powder, defoamer and leveling agent to the mixed material for a second mixing process.

[0040] Specifically, in the above step S01, the components of the polyurea waterproof coating are as described above, and will not be repeated here to save space.

[0041] Wherein, the polyaspartic acid ester polyurea resin can be prepared according to the above-mentioned preparation method of the polyaspartic acid ester polyurea resin. In one embodiment, when the above ...

Embodiment 1

[0051] A polyurea waterproof coating component formula and a preparation method thereof. The polyurea waterproof coating contains the following components by weight:

[0052]

[0053] Its preparation method technological process is as follows figure 1 As shown, it includes the following steps:

[0054] S11. Add diethyl maleate and polyetheramine EC310 with a weight of 1.80:1.63 in the reaction kettle, heat up to 50°C, react for 72 hours under stirring, and cool down to room temperature to obtain polyaspartate polyurea resin;

[0055] S12. Add anti-sedimentation agent, titanium dioxide, and dispersant to step S11, stir and disperse at high speed for 25 minutes to obtain a mixed material;

[0056] S13. After reducing the rotational speed, add talcum powder, defoamer, and leveling agent to the mixed material obtained in step S12, stir for 15 minutes, then unload, and pack to obtain a polyaspartic ester polyurea waterproof coating.

Abstract

The invention discloses waterproof polyurea paint as well as a preparation method and application thereof. The waterproof polyurea paint comprises the components in parts by weight: 3.5-4.0 parts of a poly aspartic acid ester polyurea resin, 0.010-0.015 part of an anti-settling agent, 0.50-1.0 part of titanium dioxide, 0.50-1.0 part of talcum powder, 0.010-0.015 part of a dispersing agent, 0.010-0.015 part of an antifoaming agent and 0.005-0.01 part of a flatting agent. The preparation method of the waterproof polyurea paint comprises the following steps: mixing the poly aspartic acid ester polyurea resin, the anti-settling agent, the titanium dioxide and the dispersing agent for the first time so as to obtain a mixed material, and adding the talcum powder, the antifoaming agent and the flatting agent to the mixed material for the second time. The waterproof polyurea paint disclosed by the invention has the advantages of high solid content, good stability, good water resistance, good weather resistance, good color retention, extremely good mechanical strength and extremely good adhesive force, and contains low VOC (volatile organic compounds), so that the waterproof polyurea paint is environmentally-friendly.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a polyurea waterproof coating, a preparation method and an application method thereof. Background technique [0002] With the rapid development of my country's national economy and the continuous improvement of people's living standards, as well as the improvement of architects' design concepts, buildings are becoming more and more high-end and multi-functional. Therefore, building exterior wall products are bound to develop in the direction of high-tech and multi-functional. Among them, waterproof coatings suitable for building exterior walls are one of the urgent materials. This kind of waterproof coating should overcome the shortcomings of traditional waterproof materials such as single / two-component polyurethane waterproof coating and acrylic acid emulsion waterproof coating, which are not resistant to aging, cannot be exposed, have low strength, high requirements on the construction...
