Abstract

The invention discloses a highly wear-resistant and anti-corrosion modified single-component polyurea coating and a preparation method thereof. The components of the highly wear-resistant and anti-corrosion modified one-component polyurea coating are divided into parts by weight and the parts by weight of each main component are: 35-40 parts of polytetrahydrofuran diol, 8-12 parts of dicyclohexylmethane diisocyanate, 50-54 parts of dichloromethane, 2-3 parts of liquid antioxidant, 2-3 parts of ultraviolet absorber, 2-3 parts of stabilizer, 1-2 parts of dibutyltin dilaurate, and color paste, curing agent diethyl Toluenediamine, the ratio of the volume of the curing agent component to the sum of the volume of the non-curing agent and the non-color paste components is 1:31, and the parts by weight of the color paste are 3-9 parts. The polyurea coating prepared by the invention innovatively uses dichloromethane as a diluent to achieve a good dilution effect, and the curing agent component is stored separately, so that the storage time of the polyurea coating is greatly extended.

Description

technical field [0001] The invention relates to the technical field of polyurea coatings, in particular to a highly wear-resistant and anti-corrosion modified single-component polyurea coating and a preparation method thereof. Background technique [0002] Spraying polyurea elastomer technology is a new type of solvent-free, pollution-free green construction technology. This process belongs to the rapid response spraying system, the raw material system has a fast curing speed, and the process is simple. It can be conveniently sprayed on the facade and curved surface with a thickness of more than ten millimeters without sagging. [0003] Spraying polyurea coating elastomer is sprayed on-site by various components of polyurea. Spray polyurea has excellent characteristics such as fast curing, no sagging, insensitive to temperature and moisture, little influence by ambient temperature and humidity during construction, 100% solid content, friendly to the environment, and excelle...
