[0001] The invention relates to the field of plastic paints, and in particular to a water-based 1K high-performance plastic paint and a preparation method thereof. Background Art

[0002] Plastic paint is a paint based on thermoplastic acrylic resin. Plastic paint usually uses oily water-based solvents, which does not conform to the concept of environmental protection. For the sake of green and environmental protection, water-based plastic paint products have appeared in technology. However, water-based paints currently have high fluidity and slow evaporation rate, which leads to easy sagging during construction, resulting in poor wear resistance of the paint film. Therefore, there is still room for improvement. Summary of the invention

[0003] In order to prevent water-based plastic paint from sagging and improve its wear resistance, the present application provides a water-based 1K high-performance plastic paint and a preparation method thereof.

[0016] By adopting the above technical scheme and specifically selecting the model of the water-based functional acrylic emulsion Setaqua6716, the water-based functional acrylic emulsion, the wetting and leveling agent, diethylene glycol butyl ether, dipropylene glycol butyl ether, and the polyethylene wax slurry can cooperate with each other better, the anti-sagging effect is better, and the wear resistance of the cured paint film is better.

[0017] Preferably, the model of the wetting and leveling agent is togo4100.

[0018] By adopting the above technical scheme and specifically selecting the model of the wetting and leveling agent togo4100, the water-based functional acrylic emulsion, the wetting and leveling agent, diethylene glycol butyl ether, dipropylene glycol butyl ether, and the polyethylene wax slurry can cooperate with each other better, and sagging is less likely to occur during construction, and the cured paint film has better wear resistance.

[0019] Preferably, the model of the polyethylene wax slurry is BYK-513.

[0020] By adopting the above technical scheme and specifically selecting the model of polyethylene wax slurry BYK-513, the water-based functional acrylic emulsion, wetting and leveling agent, diethylene glycol butyl ether, dipropylene glycol butyl ether, and polyethylene wax slurry can cooperate with each other better, the anti-sagging effect can be better achieved, and the cured paint film is less prone to wear.

[0021] Preferably, the covering agent is water-based aluminum silver paste.

[0022] By adopting the above technical solution and specifically selecting the water-based aluminum silver paste, the plastic paint has better hiding performance after curing.

[0023] Preferably, the thickener is a polyurethane thickener.

[0024] By adopting the above technical solution and specifically selecting the polyurethane thickener, the thickening effect is better and the anti-sagging effect is better.

[0025] Preferably, the aqueous solvent is distilled water.

[0026] By adopting the technical solution and specifically selecting distilled water, the introduction of impurities can be reduced, thereby improving the quality of latex paint.

[0027] In a second aspect, the present application provides a method for preparing a water-based 1K high-performance plastic paint, which adopts the following technical scheme: A method for preparing the above-mentioned water-based 1K high-performance plastic paint, characterized in that it comprises the following steps:

[0028] Step 1, adding a water-based functional acrylic emulsion into a container, adding a wetting and leveling agent under continuous stirring, and stirring evenly to obtain a first premix;

[0029] Step 2, adding diethylene glycol butyl ether and dipropylene glycol butyl ether to the first premix in sequence, stirring evenly, to obtain a second premix; Step 3, adding polyethylene wax slurry to the second premix, stirring evenly, to obtain a third premix;

[0030] Step 4, mix and stir the concealing agent and the aqueous solvent, then add them to the third premix, stir them evenly, and obtain a fourth premix; Step 5, add the thickener to the fourth premix, stir them evenly, and obtain a water-based 1K high-performance plastic paint.

[0031] By adopting the above technical solution, the prepared plastic paint is not prone to sagging during construction, has good wear resistance after curing, is not prone to wear, and has good quality.

[0032] In summary, this application has the following beneficial effects:

[0033] 1. Since the present application forms a special volatilization gradient of the plastic paint through the compounding of water-based functional acrylic emulsion, wetting and leveling agent, diethylene glycol butyl ether, dipropylene glycol butyl ether and polyethylene wax slurry, the plastic paint is not prone to sagging during the construction process, thereby significantly improving the wear resistance of the cured paint film, having better durability and better quality.

[0202] Step 1: add 55 kg of water-based functional acrylic emulsion into a stirring kettle, add 2 kg of wetting and leveling agent under continuous stirring at 300-500 r / min, and then stir for 3-5 minutes until the mixture is evenly stirred to obtain a first premix.

[0203] Step 2, add 3.5 kg of diethylene glycol butyl ether and 4 kg of dipropylene glycol butyl ether to the first premix in sequence, stir at 400-500 r / min for 6-8 min, and stir evenly to obtain a second premix.

[0204] Step 3, add 3.5 kg of polyethylene wax slurry to the second premix, stir evenly, 400-500 r / min, stir for 3-5 minutes, to obtain a third premix.

[0205] Step 4, 9 kg of aqueous aluminum silver paste and 22.25 kg of distilled water are mixed and stirred evenly, and then added to the third premix, stirred at 400-500 r / min for 5-7 minutes, and stirred evenly to obtain a fourth premix.

[0206] Step 5, add 0.75 kg of polyurethane thickener to the fourth premix, stir at 400-500 r / min for 10-15 min, and stir evenly to obtain a water-based 1K high-performance plastic paint.

[0207] Experiment 1

[0208] The water-based 1K high-performance plastic paint of each embodiment and comparative example was used to prepare the test samples, and the alcohol wear resistance test and the rubber wear resistance test were carried out.

[0209] 1. Test item: alcohol wear resistance

[0210] Testing environmental conditions: (23±2)℃, (50±5%)RH.

[0211] Sample pretreatment: (23±2)℃, (50±5%)RH×1h.

[0212] Test equipment:

[0213] Serial number name model Calibration validity period 1 Abrasion testing machine 339 2025.06.03 2 95% medical alcohol --- --- 3 Clean cloth --- ---

[0214] Experimental conditions: Refer to Method B in GBT 23989-2009, the method for determining the water resistance of coatings by solvent wiping, use 4 layers of dust-free cloth dipped in 95% alcohol and test 50 times under a load of 500g

[0215] Experimental requirements: Visually check that no base material is exposed.

[0216] Experimental results: 1. The test sample with sagging had obvious bottom exposure after 50 tests; 2. The test sample without sagging had no obvious scratches after 50 tests.

[0217] The experimental pictures of Examples 1-3 are shown in Figure 1-3 .

[0218] The experimental pictures of comparative examples 1-6 are shown in Figure 4-9 .

[0219] 2. Test item: Rubber test

[0220] Testing environmental conditions: (23±2)℃, (50±5%)RH.

[0221] Sample pretreatment: (23±2)℃, (50±5%)RH×1h.

[0222] Test equipment:

[0223] Serial number name model Calibration validity period 1 Abrasion testing machine 339 2025.06.03 2 CS-10 Eraser --- ---

[0224] Experimental conditions: Use CS10 eraser and test 50 times under a load of 500g, and visually check the test position.

[0225] Experimental requirements: Visually check that no base material is exposed.

[0226] Experimental results: 1. The test sample with sagging had obvious bottom exposure after 50 tests; 2. The test sample without sagging had slight scratches after 50 tests, but no bottom exposure.

[0227] The experimental pictures of Examples 1-3 are shown in Figure 10-12 .

[0228] The experimental pictures of comparative examples 1-6 are shown in Figure 13-18 .

[0229] In summary, Examples 1-3 use special types of water-based functional acrylic emulsion, wetting and leveling agent, polyethylene wax slurry and diethylene glycol butyl ether, dipropylene glycol butyl ether for special compounding, so that the plastic paint is not prone to sagging during the construction process, thereby significantly improving the wear resistance of the cured paint film.
