Abstract

The invention relates to a mechanical anti-aging coating and a preparation method thereof. The preparation method comprises steps as follows: (1) weighing components in parts by weight as follows: 5-10 parts of rare-earth cerium fluoride, 7-11 parts of pentaerythritol, 4-8 parts of sodium hexametaphosphate, 3-6 parts of alkyd resin, 1-3 parts of diatomite, 9-14 parts of an acrylic emulsion, 6-10 parts of a shell powder and 4-9 parts of talc; (2) adding rare-earth cerium fluoride and pentaerythritol to a reaction kettle, adding the acrylic emulsion after stirring, heating the mixture to 80 DEG C, and stirring the mixture for a reaction; (3) adding sodium hexametaphosphate, and stirring the mixture at the rotating speed of 1,200 rpm for 60 min; (4) adding alkyd resin and diatomite, heating the mixture to 70 DEG C, stirring the mixture at the constant temperature, and cooling the mixture to the room temperature; (5) adding the shell powder, and stirring the mixture to be uniform to obtain a mixed solution; (6) adding the mixed solution to a stirrer and adding the talc. The coating has the benefits as follows: the coating is high-temperature-resistant, cannot age easily and cannot age and fall off easily even under the high-temperature exposure condition.

Description

technical field [0001] The invention relates to the field of mechanical coatings, in particular to a mechanical anti-aging coating and a preparation method thereof. Background technique [0002] Paint is a chemical mixture paint that can firmly cover the surface of objects for protection, decoration, marking and other special purposes. [0003] Coatings belong to organic chemical polymer materials, and the formed coating film belongs to the type of polymer compounds. According to the classification of modern chemical products, coatings belong to fine chemical products. Modern coatings are gradually becoming a class of multifunctional engineering materials and an important industry in the chemical industry. Existing coatings for mechanical equipment are prone to aging and peeling off under high temperature exposure, resulting in poor appearance. Contents of the invention [0004] In summary, in order to overcome the deficiencies of the prior art, the technical problem to...
