Foaming type vehicle-bottom chip-resistant paint

Abstract

The invention discloses a foaming type vehicle-bottom chip-resistant paint, which comprises the following compositions by mass percent: 20-35% of PVC copolymer resin, 20-35% of a filler, 25-35% of a plasticizer, 1-15% of a tackifier, 3-5% of a hygroscopic agent, 1-5% of a stabilizer, and 1-5% of a foaming agent. According to the invention, the foaming type vehicle-bottom chip-resistant paint can replace the traditional non-foaming type vehicle-bottom chip-resistant paint, reduces the vehicle weight by virtue of the self-expansion of a sealant, and can reduce loss.

Description

technical field [0001] The invention relates to a foamed car bottom anti-stone chip paint. Background technique [0002] Foamed underbody anti-stone chip paint is a single-component gray and dark gray paste product with PVC resin as the main component. It is coated on the bottom of the car and hardened after the coating drying oven to play an adhesive force. Thermosetting products for soundproof, watertight, shockproof and rustproof purposes. [0003] Traditionally, non-foaming underbody anti-stone impact coatings are used. The working thickness is required to be more than 1.5mm, and the specific gravity is about 1.45, which greatly increases the weight of the car body. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a foamed anti-stone chip paint for car bottoms with a small specific gravity. [0005] In order to solve the above-mentioned technical problems, the technical solution adopted in the present invent...
