Problems solved by technology

[0003] However, after the existing armor is applied to the chassis of the car, the armor will fall off from the chassis of the car over time, so that the chassis of the car will be hit by flying stones and gravel, and the metal of the chassis of the vehicle will be eroded by moisture, acid rain, and salt. Rust and rust, the owner's driving safety is affected, resulting in poor heat conduction of the chassis iron plate

Abstract

The invention discloses a composite graphene thermal-insulation anticorrosive armor coating applied to automobiles. The coating comprises the following raw materials in parts by weight: epoxy resin, deionized water, graphene powder, a graphene dispersion liquid, a flatting agent, a wetting dispersant, an ethanol solvent, pigment and filler, an anionic acrylic emulsion, a defoaming agent, a curingagent, polyaniline, a coalescing agent, isooctyl ester, a thickening agent, dimethyl fumarate, a releasing preservative, a toughening agent and a silane coupling agent. The preparation method by usingthe raw materials comprises the following steps: (1) preparing a mixed solution; (2) preparing mixed slurry; (3) preparing the coating. The coating disclosed by the invention has no toxicity, high covering rate and high adhesiveness and is not fall off from an automobile chassis easily; impact of the flying stones and grit can be prevented; and erosion of moisture, acid rain and salt to metal ofthe automobile chassis is avoided; so that the chassis is prevented from rusting and being eroded, and the driving safety of vehicle owners is protected.

Description

technical field [0001] The invention relates to the field of automobile coatings, in particular to a composite graphene heat-insulating and anti-corrosion armor coating applied to automobiles and a preparation method thereof. Background technique [0002] In the current technology, the car chassis is equipped with armor. The armor can be sprayed on the exposed parts of the vehicle chassis, wheel hub, fuel tank, car lower panel, trunk, etc., and a firm elastic protective layer will be formed after quick drying. [0003] However, after the existing armor is applied to the chassis of the car, the armor will fall off from the chassis of the car over time, so that the chassis of the car will be hit by flying stones and gravel, and the metal of the chassis of the vehicle will be eroded by moisture, acid rain, and salt. Rust and corrosion will affect the driving safety of the car owner, resulting in poor heat conduction of the chassis iron plate. [0004] Therefore, the developmen...
