Problems solved by technology

The baking temperature of the existing domestic amino baking varnishes generally hovers around 130°C, and the actual salt spray resistance of the baking paint does not exceed 72 hours. If the baking temperature is too high, the coating time is longer and the salt spray resistance time is shorter. Its protection against the chassis is not good

Abstract

The invention provides a low-temperature fast-dry amino automobile chassis paint and a production method thereof, wherein, the paint consists of B-12 resin, medium pigment carbon black, compound ferrotitanium powder, ultra-fine mica powder, an auxiliary agent, sealed paratoluenesulfonic acid BYK-450 and BR-167 amino resin; B-12 resin is prepared by octadecenoic acid, benzoic acid, pentaerythritol, phthalic anhydride, dimethylol propionic acid, and trimethyl benzene. The automobile chassis paint adopts special B-12 resin synthetic route to lead the polymer chain to have more active functional groups simultaneously to be matched with the blocked paratoluenesulfonic acid, reduces the baking temperature of the existing amino paint from 130 DEG C to 90 DEG C and reduces the curing film-forming time from 1 hour to half an hour. As the paint film has high crosslinking density, compound ferrotitanium powder and squamous anti-rust pigment are matched for use, and the polyaniline is used for improving the anticorrosive potentials, thus leading the salt spray resistance of the paint to achieve 150 hours and improving the protection performance and the coating efficiency.

Description

Technical field: [0001] The invention belongs to the technical field of new materials, in particular to a low-temperature quick-drying amino car chassis paint and a production method thereof. Background technique: [0002] With the development of my country's automobile industry, the anti-corrosion requirements for automobile chassis paint are getting higher and higher. At the same time, modern automobile assembly line production requires high efficiency, low energy consumption, and environmental protection. The baking temperature of the existing domestic amino baking varnishes generally hovers around 130°C, and the actual salt spray resistance of the baking paint does not exceed 72 hours. If the baking temperature is too high, the coating time is longer and the salt spray resistance time is shorter. Its protection against the chassis is not good. Invention content: [0003] The invention provides a low-temperature quick-drying amino car chassis paint, which greatly impr...
