Low temperature curing color coil suede coating

Abstract

The invention relates to a low temperature curing color coil coating, in particular to a low temperature curing color coil suede coating which comprises paint and a curing agent, wherein the paint and the curing agent are stored individually. The formula of the paint comprises the following components by weight proportion: 50% to 70% of saturated polyester resin, 5% to 8% of completely methylated melamine-formaldehyde resin, 1% to 2% of ethylenediamine surface active agent, 0.5% to 0.8% of closed p-toluenesulfonic acid catalyst, 5% to 20% of rutile titanium pigment, 5% to 19% of pigment, 3% to 5% of propylene glycol aether acetate, 2% to 5% of dibasic acid dimethyl ester, 5% to 10% of aromatic hydrocarbon solvent, 0.3% to 0.8% of dispersant and 0.3% to 0.8% of polytetrafluoroethylene wax.

Description

technical field [0001] The invention relates to a low-temperature curing color coil coating, in particular to a low-temperature curing color coil suede coating. Background technique [0002] At present, the domestic color steel plate is developing very fast, but the variety of color steel plate is relatively single, and the application field is limited to the construction material industry. According to incomplete statistics, there are nearly 200 color steel plate production lines in China, with a production capacity of 15 million tons per year. , the actual output reaches 8 million tons / year, and the production capacity is far from saturated, so it is necessary to broaden the application field of color steel plate, and to broaden the application field depends largely on the coating, the performance and variety of coating to a large extent It determines the performance and variety of color steel plates. Existing velvet paint adopts all rubber paint and fluff powder to mix, ...
