[0025] The preparation method of the balance control agent is as follows: Weigh the raw materials of each component according to the above weight ratio, add them into the blending reactor in turn, stir for 30 minutes until uniform, and then pass the test.
[0026] The mouthpiece solvent is composed of the following components in parts by weight: aromatic hydrocarbon solvent 25-35, ester solvent 42-52, alcohol solvent 11-17, leveling aid 0.7-1.5, one-component acrylic resin 5-11. Among the components that make up the mouth solvent, the aromatic hydrocarbon solvent is one or more of xylene, 100# solvent oil, and 120# solvent oil; the ester solvent is butyl acetate, propylene glycol methyl ether acetate, ethylene glycol A mixture of ether acetate and dibasic acid ester; the alcohol solvent is one or a mixture of propanol and n-butanol.
[0027] The preparation method of the spout solvent is as follows: weigh the raw materials of each component according to the above weight ratio,...
Embodiment 1
[0032] For example of repairing white pearls, weigh 18g of acrylic resin, 3g of amino resin, 9g of xylene, 11g of butyl acetate, 57g of cellulose acetate butyrate (CAB), 0.7g of UV additives, 0.8g of leveling additives, and add in order Reactor, put on a high-speed disperser and keep stirring at a high speed for 30 minutes until it is uniform, and then the required balanced color control agent is obtained. Weigh xylene 15g, 100# solvent 11g, 120# solvent 4g, butyl acetate 25g, n-butanol 14g, propylene glycol methyl ether acetate 14g, ethylene glycol ethyl ether acetate 6g, dibasic acid ester 2g, leveling aid Add 1.1g of agent and 9g of one-component acrylic resin, put it on a high-speed disperser and keep stirring at a medium speed for 10 minutes until it is uniform, and then the required mouthpiece solvent is obtained. Weigh 42g of xylene, 28g of butyl acetate, and 33g of propylene glycol methyl ether acetate in sequence, and keep stirring at a medium speed for 5 minutes on a...
Embodiment 2
[0035] For the example of repairing light yellow silver, weigh 15g of acrylic resin, 4g of amino resin, 10g of xylene, 10g of butyl acetate, 54g of cellulose acetate butyrate (CAB), 0.8g of UV additive, and 0.7g of leveling additive into the letdown In the tank, use a high-speed disperser to keep stirring at a high speed for 30 minutes until it is uniform, and then the desired balanced color control agent is obtained. Weigh in turn 13g of xylene, 12g of 100# solvent, 5g of 120# solvent, 28g of butyl acetate, 12g of n-butanol, 12g of propylene glycol methyl ether acetate, 7g of ethylene glycol ether acetate, 3g of dibasic acid ester, leveling aid Add 1.0g of agent and 7g of one-component acrylic resin into the paint mixing tank, and keep stirring at a medium speed on a high-speed disperser for 10 minutes until it is uniform, and the required mottled solvent is obtained. Sequentially weigh 40g of xylene, 29g of butyl acetate, and 35g of propylene glycol methyl ether acetate, add...
