preparation example Construction

[0033] Correspondingly, the present invention also provides the preparation method of above-mentioned polyurea waterproof coating, and described preparation method comprises the following steps:

[0034] Step S01: Obtain each component according to the components and contents in the polyurea waterproof coating;

[0035] Step S02: performing the first mixing treatment on polyaspartate polyurea resin, anti-sedimentation agent, titanium dioxide, and dispersant to obtain a mixed material;

[0036] Step S03: adding talcum powder, defoamer and leveling agent to the mixed material for a second mixing process.

[0037] 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.

[0038] Preferably, the polyaspartic acid ester polyurea resin can be obtained by reacting diethyl maleate and polyether amine at 45-55°C as described above, diethyl maleate and polyether amine The weight ratio of polyetheramin...

Abstract

The invention discloses a polyurea waterproof coating, a preparation method and a use method thereof and carbamide resin. The polyurea waterproof coating comprises the following components in parts by weight: 3.5-4.0 parts of polyaspartic acid ester carbamide resin, 0.010-0.015 part of anti-settling agents, 0.50-1.0 part of titanium white, 0.50-1.0 part of talcum powder, 0.010-0.015 part of dispersing agents, 0.010-0.015 part of deforming agents and 0.005-0.01 part of flatting agents. The polyurea waterproof coating disclosed by the invention adopts the polyaspartic acid ester carbamide resin as a matrix component and has the advantages of high solid content (more than or equal to 65%w/w), good stability, low VOC content and environmental friendliness under the action of the components, namely the anti-settling agents, the titanium white, the talcum powder, the dispersing agents, the deforming agents, the flatting agents and the like.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a polyurea waterproof coating, its preparation and use method and polyurea resin. 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 envi...
