Abstract

The invention discloses a polyurea floor coating material, a preparation method and a use method thereof, and a polyurea resin, wherein the polyurea resin is a polyaspartic ester polyurea resin, and diethyl maleate and 3,3-dimethyl-4,4-diaminodicyclohexylmethane are used as raw materials and are subjected to a reaction for 70-74 h at a temperature of 60-80 DEG C according to a weight ratio of 1.0:1.55-1.60 to prepare the polyaspartic ester polyurea resin. According to the present invention, the polyaspartic ester polyurea resin can stably exist at a normal temperature; the polyurea floor coating material can be prepared by using the polyaspartic acid ester polyurea resin as the matrix component and adding the filler, the auxiliary agent and the like; and after the polyurea floor coating material and the HDI type curing agent are mixed according to a certain ratio, the advantages of good wear resistance, good aging resistance, good water resistance, controlled elasticity and high impactresistance can be achieved.

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...
