Embodiment 1

[0015] The first step: Weigh various raw materials according to the ratio of mass and number described below: 33 parts of deionized water; 20 parts of methyl ethyl ketone; 16 parts of maleic anhydride; 0.8 parts of dimethylethanolamine; 6 parts of styrene; 3.5 parts of ethanol; 2 parts of butanol; 1.5 parts of polyethylene wax.

[0016] Step 2: Put deionized water, triethylamine and ethanol into the reaction kettle with a reflux condenser, turn on the reflux condenser to cool the water and start stirring, then slowly add one-third of the mass of methyl ethyl ketone and butanol, stop heating after raising the temperature to 60°C, continue to stir, and lower the temperature to 36°C after holding for 4.5 hours;

[0017] The third step: then add maleic anhydride, dimethylethanolamine and styrene and stir evenly;

[0018] Step 4: After finally adding the remaining methyl ethyl ketone and polyethylene wax, adjust the pH value of the system at 8.5, and filter to obtain the quick-dry...

Embodiment 2

[0020] The first step: Weigh various raw materials according to the ratio of mass and number as described below: 37 parts of deionized water; 30 parts of methyl ethyl ketone; 18 parts of maleic anhydride; 1 part of dimethylethanolamine; 8 parts of styrene; 5 parts of triethylamine 4.5 parts of ethanol; 4 parts of butanol; 2.5 parts of polyethylene wax.

[0021] Step 2: Put deionized water, triethylamine and ethanol into the reaction kettle with a reflux condenser, turn on the reflux condenser to cool the water and start stirring, then slowly add one-third of the mass of methyl ethyl ketone and butanol, stop heating after raising the temperature to 55°C, continue to stir, and lower the temperature to 35°C after keeping the temperature for 4 hours;

[0022] The third step: then add maleic anhydride, dimethylethanolamine and styrene and stir evenly;

[0023] Step 4: After finally adding the remaining methyl ethyl ketone and polyethylene wax, adjust the pH value of the system to ...

Embodiment 3

[0025] The first step: Weigh various raw materials according to the ratio of mass and number described below: 35 parts of deionized water; 25 parts of methyl ethyl ketone; 17 parts of maleic anhydride; 0.9 parts of dimethylethanolamine; 7 parts of styrene; 4 parts of ethanol; 3 parts of butanol; 2 parts of polyethylene wax.

[0026] Step 2: Put deionized water, triethylamine and ethanol into the reaction kettle with a reflux condenser, turn on the reflux condenser to cool the water and start stirring, then slowly add one-third of the mass of methyl ethyl ketone and butanol, stop heating after raising the temperature to 70°C, continue stirring, and lower the temperature to 38°C after holding for 5 hours;

[0027] The third step: then add maleic anhydride, dimethylethanolamine and styrene and stir evenly;

[0028] Step 4: After finally adding the remaining methyl ethyl ketone and polyethylene wax, adjust the pH value of the system to remain at 9, and filter to obtain the quick-...

Abstract

Quick-drying paint for metal is prepared from components in parts by mass as follows: 30-40 parts of deionized water, 15-40 parts of methyl ethyl ketone, 15-20 parts of maleic anhydride (P.R57:1), 0.8-1 part of dimethylethanolamine, 4-10 parts of styrene, 2.0-5 parts of triethylamine, 3-5 parts of ethanol, 1-4 parts of butanol and 1.0-3 parts of polyethylene wax. According to the quick-drying paint for the metal and a preparation method thereof, the quick-drying paint is hard, short in silk and excellent in leveling property, has the viscosity value of 8-14 at 400 rmp, is anti-set-off, is dried completely within 0.8 s, has the large yield value, can be widely applied and continuously replace existing products.

Description

technical field [0001] The invention relates to a paint for metal, in particular to a quick-drying paint for metal. Background technique [0002] Metal primer belongs to solvent-based outdoor paint, which is produced with thermoplastic acrylic and polyurethane modified acrylic resin, flashing metal powder, special additives, etc. Compared with general weather-resistant primers, metal primers have better hiding power and longer durability. At the same time, they also have luxurious metal appearance, unique polarizing effect and moderate price, comparable to aluminum siding. [0003] Paint English name: paintercoating. Paint is a chemical mixture coating that can firmly cover the surface of objects for protection, decoration, marking and other special purposes. The relatively authoritative book "Painting Technology" in the Chinese coatings industry defines it as follows: "Painting is a material that can be coated on the surface of an object by different construction techniqu...
