Summary of the invention
To the problems referred to above, the present invention discloses and a kind ofly in baking vanish solidifies, adds sulphonate, in order to reduce solidification value, shortens set time.。
Technical scheme of the present invention is such: the application of sulphonate in baking vanish is that the accelerator during sulphonate is solidified as baking vanish uses
The application of above-mentioned sulphonate in baking vanish is characterized in that, described sulphonate addition is 0.1～1.0wt% (being that the sulphonate addition is a sulphonate weight percent 0.1～1.0%).
The application in baking vanish of above-mentioned sulphonate is characterized in that described sulphonate is used to shorten the baking vanish solidified time.
The above-mentioned application of sulphonate in baking vanish is characterized in that described sulphonate is used to reduce baking vanish solidified temperature.
Further, the application of above-mentioned sulphonate in baking vanish is characterized in that, described sulphonate is the phenylbenzimidazole sulfonic acid ester.
Advance one and mend, the application of above-mentioned sulphonate in baking vanish is characterized in that, described sulphonate is basic sulphonate for how.
Further, the application of above-mentioned sulphonate in baking vanish is characterized in that, described phenylbenzimidazole sulfonic acid ester is DBS, p-toluenesulfonic esters, to the acid dimethyl ester.
Further, the application of above-mentioned sulphonate in baking vanish is characterized in that, it is described that how basic sulphonate is dinonylnaphthalene sulfonic acid ester, docosyl napsylate.
Compared with prior art, the present invention's advantage specific as follows:
1. the application of the disclosed sulphonate of the present invention in baking vanish; This sulphonate adds the baking vanish system can not cause the system gel; Be warming up to certain temperature ability quick catalysis hydroxyl, carboxyl or the polymkeric substance of carboxamido-group and the reaction of its solidifying agent, reduce solidification value, shorten set time.
2. the application of the disclosed sulphonate of the present invention in baking vanish compared as the application of the cooling agent in the baking vanish with sulfonic amine salt, has good yellowing resistance, is applicable to tinted paints such as baking vanish varnish or white paint.
3. the application of the disclosed sulphonate of the present invention in baking vanish used as the cooling agent in the baking vanish with sulphonate and to be compared, and institute's temperature is low, has practiced thrift energy consumption.
4. the application of the disclosed sulphonate of the present invention in baking vanish enlarged the use range of sulphonate.
Principle of the present invention is such:
Sulfonic acid substance carries out the sealing treatment esterification, and high temperature (80～140 ℃) deblocking discharges acid, and the catalytic curing reaction is carried out.
