preparation example Construction

[0034] Correspondingly, the present invention also provides the preparation method of above-mentioned polyurea floor paint, and described preparation method comprises the steps:

[0035] Step S01: Obtain each component according to the components and contents in the polyurea floor coating;

[0036] Step S02: Stir and disperse polyaspartate polyurea resin, titanium dioxide, dispersant, and barium sulfate or glass powder at high speed for 20-30 minutes;

[0037] Step S03: After reducing the rotation speed, add talc powder or fine sand and stir for 5-15 minutes, then add defoamer and leveling agent, stir for 10-20 minutes, unload and pack to obtain polyaspartic acid ester polyurea floor coating.

[0038] Wherein, in step S03, when the raw material composition of the polyurea floor coating also includes a color paste, the color paste is added together with the defoamer and the leveling agent.

[0039] In the above step S02, the polyaspartate polyurea resin can directly add titan...

Abstract

The invention discloses a polyurea floor coating and preparation and application methods thereof as well as carbamide resin. The carbamide resin is polyaspartic acid ester carbamide resin; the polyaspartic acid ester carbamide resin is prepared by reacting diethyl maleate and 3,3-dimethyl-4,4-methylenebis(cyclohexylamine) as raw materials at 60-80 DEG C for 70-74 DEG C, with the weight ratio of the diethyl maleate to the 3,3-dimethyl-4,4-methylenebis(cyclohexylamine) is 1.0 to (1.55-1.60). The polyaspartic acid ester carbamide resin can stably exist at a room temperature; the polyaspartic acid ester carbamide resin is taken as a base component; and packing, an assistant and the like are added, so as to prepare the polyurea floor coating disclosed by the invention. The polyurea floor coating and an HDI curing agent are mixed to use at a certain ratio, so that the polyurea floor coating has the advantages of good abrasive resistance, ageing resistance, waterproofness, controllable elasticity and high-strength shock resistance.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a polyurea floor 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 industrial floors, traditional epoxy resin floors occupy a large market, but due to their poor flexibility, poor impact resistance, slow drying, and thin one-time film formation, there are many restrictions in the use process. [0003] Therefore, the prior art has yet to be developed. Contents of the invention [0004] The object of the present invention is to overcome the above-mentioned deficiencies of the prior ar...
