Abstract
Description
technical field
[0001] The invention relates to the preparation of a water-based paint, in particular to a rare-earth modified water-based alkyd resin antibacterial luminous paint and a preparation method thereof, belonging to the technical field of water-based functional paints. Background technique
[0002] With the rapid development of my country's economy, coatings have been more and more widely used in industry and agriculture, national defense, scientific research and people's lives. Coatings are a kind of coating that is coated on the surface of objects and forms a film under certain conditions to protect and decorate. It is a kind of liquid or fixed material with specific functions. At present, there are some shortcomings in coatings, such as the surface of the decorated object is dull and unchanged, and the luminous effect cannot be displayed at night. Some raw materials are toxic or flammable and explosive, and have no environmental protection performance. Production...
Examples
Embodiment 1
[0035] A rare earth modified water-based alkyd resin X, the steps are as follows:
[0036] a) In the multifunctional reaction kettle, add 8.5 parts of dehydrated linseed oil, 7.8 parts of maleic anhydride, 2.2 parts of 1,4-butanediol, 5.8 parts of trimethylolpropane, dimethylol 1.8 parts of propionic acid and 8.0 parts of xylene, N 2 , to remove the O in the reactor 2 ;
[0037] b) Heat up to 105-110°C to reflux, keep it warm for 0.5h, remove part of the water, quickly raise the temperature to 150-160°C, stir fully until the material is dissolved, then stir and keep warm at a speed of 200-400 r / min for 1h , then heat up to 180°C at a speed of 20°C / h for 1 hour, add 1.4 parts of benzoic acid, continue to heat for 1 to 1.5 hours, heat up to 210 to 220°C at a speed of 20°C / h, and heat for 3.0 to 3.5 hours , until the measured acid value is consistent with the design value, the water produced by the reaction is separated by a water separator;
[0038]c) Cool down to 160°C at a...
