Abstract

The invention discloses a corrosion-resistant coating for construction machinery and a preparation method thereof. The coating comprises the following raw materials in parts by weight: 50-60 parts oforganosilicon epoxy resin polymer, 10-20 parts of fluorocarbon resin, 5-10 parts of polysiloxane, 3-7 parts of modified talcum powder, 3-5 parts of carboxylated butadiene-acrylonitrile rubber, 2.5-5.5parts of calcined metakaolin, 1-3 parts of mica powder, 2-4 parts of glass fibers, 3-6 parts of nanometer silicon micropowder, 1.5-3.5 parts of nanometer calcium carbonate, 1-3 parts of a heat-resistant agent, 2-5 parts of a preservative, 0.5-0.8 part of a dispersant, 0.3-0.7 part of a film-forming auxiliary and 43-47 parts of a solvent. The coating has high strength, strong impact resistance, good weather resistance and excellent corrosion resistance, and the coating is capable of playing a good protective role for construction machinery.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a corrosion-resistant coating for construction machinery 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. At present, coatings are widely used in construction machinery. [0003] In coatings applied to construction machinery, especially in chemical synthesis production, especially storage machinery or processing machinery involving chemicals, mechanical coatings are required to have good chemical resistance; at the same time, in the processing of other machinery, Mechanical vibration is also one of the factors that reduce the service life of the coating. It is not uncommon for the coating on the mechanical surface to fall off and loosen due to long-term mechanical vibration. Therefore, it is often necessary f...
