Problems solved by technology

[0002] Because the car shell is often exposed to the high temperature environment outside, the high temperature will cause the loss of auto parts, and may even cause the car to spontaneously ignite. At the same time, if the heat accumulated in the car shell cannot be dissipated quickly, it will also affect the performance of the car. cause harm

Abstract

The invention discloses a cooling flame-retardant coating of an automobile shell, and relates to the technical field of coatings. Acrylic acid and ethylene-propylene-diene monomers are used for conducting modifying treatment on epoxy resin, so that the properties of cooling and high temperature resistance of the epoxy resin are improved; a titanate coupling agent and methyl 4-hydroxybenzoate are adopted for conducting modifying treatment on graphene, a hydroxyl active site of methyl 4-hydroxybenzoate is used for a reaction of the graphene and active groups in the resin, and therefore the capacities of flame retardancy and cooling of the resin are improved; meanwhile, the problems are solved that a coating easily coagulates, is not dispersed with uniformity, and is not combined with an organic raw material tightly. A preparation technology for the cooling flame-retardant coating is efficient, environmentally friendly, low in cost and suitable for industrial production, and will not generate environmental pollution.

Description

Technical field: [0001] The invention relates to the technical field of coatings, in particular to a heat-dissipating and flame-retardant coating for an automobile shell. Background technique: [0002] Because the car shell is often exposed to the high temperature environment outside, the high temperature will cause the loss of auto parts, and may even cause the car to spontaneously ignite. At the same time, if the heat accumulated in the car shell cannot be dissipated quickly, it will also affect the performance of the car. cause harm. Invention content: [0003] The technical problem to be solved by the present invention is to provide a heat-dissipating and flame-retardant coating for automobile shells with excellent heat dissipation performance and strong resistance to high temperature. [0004] Technical problem to be solved by the present invention adopts following technical scheme to realize: [0005] A heat-dissipating and flame-retardant coating for an automobile...
