Patent CN200810021672.5 proposes a method for preparing quick-drying amino baking varnish by using alkyd or amino resin, amino resin, polybasic dibasic acid ester, auxiliary agent and diluent. Although the baking time of the obtained amino baking varnish is shortened, the The required baking temperature is still very high (170°C); patent CN201010590719.7 discloses an automotive finish that can be baked at low temperature, but it still needs to be baked at 140°C for 30 minutes; patent CN200810233988.0 provides a The amino baking varnish prepared with special alkyd resin can be cured by baking at 90°C for 30 minutes, but this amino baking varnish cannot be applied to ordinary alkyd resin or acrylic resin, which limits its promotion

Abstract

The invention relates to amino stoving varnish, and in particular to amino stoving varnish capable of capable of being cured quickly at a low temperature. The amino stoving varnish comprises the following components in parts by weight: 50-60 parts of hydroxy acrylic resin or alkyd resin, 10-20 parts of amino resin, 1-5 parts of functional auxiliary, 0.1-0.5 part of flatting agent, 0.1-0.5 part of antifoaming agent and 10-20 parts of diluent. A preparation method of the amino stoving varnish provided by the invention is simple, and the prepared product has strong applicability and good quality.

Description

technical field [0001] The invention relates to an amino baking varnish, in particular to an amino baking varnish capable of fast curing at low temperature. Background technique [0002] Amino baking varnish uses acrylic resin or alkyd resin and amino resin with hydroxyl groups as the main film-forming substances. It is packaged in a single component at room temperature. It has a three-dimensional network structure, high hardness, excellent adhesion, high gloss, good gloss and color retention, and is widely used in the coating of automobiles, ships, and aircraft. [0003] After the amino baking varnish is painted, it generally needs to be baked at 140~180°C for more than 30 minutes to be completely cured, which brings many problems to the use of amino baking varnish. On the one hand, high-temperature baking causes a large amount of energy consumption in the coating process, and is more likely to bring hidden dangers to production safety; on the other hand, longer baking tim...
