Heavy equipment cab water-based two-component energy-saving coating

Abstract

The invention relates to the technical field of water-based coatings, and discloses a heavy equipment cab water-based two-component energy-saving coating which comprises a component A and a component B, the component A is prepared from the following raw materials in percentage by weight: 50 to 55 percent of hydroxyl acrylic acid dispersion, 12 to 15 percent of titanium dioxide coated mica powder, 10 to 12 percent of hollow glass beads, 6 to 11 percent of IR coloring pigment, 1 to 3 percent of auxiliaries and 5 to 7 percent of water, and the component B is prepared from the following raw materials in percentage by weight: 80 percent of isocyanate and 20 percent of PGDA. According to the heavy equipment cab water-based two-component energy-saving coating, a paint film has excellent ultraviolet aging resistance, dry-wet alternating resistance and cold-hot alternating resistance, and can resist artificial accelerated aging for more than 1000 hours; the paint film is resistant to acid, alkali, fuel oil and lubricating oil; the reflectivity of the paint film to infrared rays reaches 87% or above, the temperature rising speed is greatly reduced under sunlight irradiation or radiation of other heat sources, and the surface temperature can be reduced by 10-25 DEG C; and the paint film has a good thermal resistance effect, and the heat conductivity coefficient is lower than 0.025 W / (m * K).

Description

technical field [0001] The invention relates to the technical field of water-based coatings, in particular to a water-based two-component energy-saving coating for heavy equipment cabs. Background technique [0002] All coatings that use water as a solvent or as a dispersion medium can be called water-based coatings. According to the type of binder in the coating, water-based coatings are divided into two categories: natural water-based coatings of natural substances or minerals (such as potassium silicate) And artificial synthetic resin (such as acrylic resin) petrochemical water-based coatings, the cab is an important part of the body of trucks and special vehicles, it is the place where professional drivers work day and night, and its structure is directly related to the driver's safety, work Efficiency and health, the cab generally adopts a metal thin shell structure, and is flexibly connected with the frame, does not bear load, and belongs to a non-load-bearing body. ...
