Abstract

The invention discloses an antiflaming impacting resistance automobile coating material, and relates to the technical field of coating materials. Crylic acid and ethylene-propylene-diene monomer are adopted for modifying epoxy resin, and the heat dissipating and impacting resistance performance of the epoxy resin is improved; a titanate coupling agent and methylparaben are adopted for modifying graphene, hydroxyl active sites of the methylparaben are utilized for making the graphene react with active groups in resin, and the heat dissipating and impacting resistance capacity of the resin is improved; the problems that the material can be easily coagulated, dispersion is uneven, and bonding between the material and an organic raw material is not tight are solved; the preparation technologyis efficient and environmentally friendly, the cost is low, pollution on the environment cannot be generated, and the material is suitable for industrial production.

Description

Technical field: [0001] The invention relates to the technical field of coating materials, in particular to a flame-retardant and impact-resistant automotive coating material. Background technique: [0002] In 2004, China's automobile output has reached 5 million, but from a global perspective, my country's car ownership is still low. According to the specific situation of our country, the number of automobiles in my country should be 140 million. Therefore, my country's automobile industry still has a very large Large market space. Such a large automobile market also needs a large amount of automobile paint correspondingly, and this demand will continue for a long time and gradually increase. At present, a large part of the automotive paint industry uses products from imported paint companies, and domestic brands occupy a small share. A large part of the reason for this situation is that the customer's requirements for paint performance and environmental protection cannot ...
