Embodiment 1
[0038] see Figure 1 to Figure 5 , the preparation method of the water-based automotive paint of strong adhesion provided by the present embodiment, such as figure 1 shown, including the following steps:
[0039] S1: Add 35-55 parts of water-dispersed modified acrylic resin, 10-15 parts of water-based curing agent and 25-30 parts of absolute ethanol into a three-necked flask, heat in a water bath at 50°C and stir magnetically, and control the stirring speed to 85r / min , stirred for 30 minutes, heated to 60°C, kept warm for 1 hour, and used as liquid A for later use. The water-dispersed modified acrylic resin is made of the following raw materials in parts by weight: 15-20 parts of methyl methacrylate, 10-15 parts of acrylic acid, 5-10 parts of ethyl acrylate, 35-50 parts of deionized water, 3-8 parts of monoglyceride laurate, 0.3-0.6 parts of potassium persulfate, 8-12 parts of vinyltrimethoxysilane, 35-50 parts of none water ethanol;
[0040]S2: Add 3-5 parts of pigments a...
Embodiment 2
[0055] The preparation method and the preparation equipment of the water-based automotive paint of strong adhesion that the present embodiment provides, it is basically identical with embodiment 1, and its difference is:
[0056] S1: Add 35 parts of water-dispersed modified acrylic resin, 10 parts of water-based curing agent and 25 parts of absolute ethanol into a three-necked flask, heat in a water bath at 50°C and stir magnetically, control the stirring speed at 85r / min, stir for 30min, and heat up to 60°C, keep warm for 1 hour, and use it as liquid A for later use;
[0057] S2: Add 3 parts of pigments and fillers and 25-30 parts of absolute ethanol into a beaker, heat in a water bath at 45°C, stir at a constant speed for 15 minutes, then add 0.5 parts of initiator, raise the temperature to 55°C, and stir magnetically at a speed of 180r / min for 30 minutes. liquid B;
[0058] S3: Pour liquid A into liquid B, stir at a constant speed for 5 minutes, add 1 part of cross-linking...
Embodiment 3
[0063] The preparation method and the preparation equipment of the water-based automotive paint of strong adhesion that the present embodiment provides, it is basically identical with embodiment 1,2, and its difference is:
[0064] S1: Add 45 parts of water-dispersed modified acrylic resin, 12 parts of water-based curing agent and 28 parts of absolute ethanol into a three-necked flask, heat in a water bath at 50°C and stir magnetically, control the stirring speed at 85r / min, stir for 30min, and heat up to 60°C, keep warm for 1 hour, and use it as liquid A for later use. The water-dispersed modified acrylic resin is made of the following raw materials in parts by weight: 18 parts of methyl methacrylate, 12 parts of acrylic acid, 8 parts of ethyl acrylate, and 40 parts of deionized Water, 5 parts of monoglyceride laurate, 0.5 parts of potassium persulfate, 10 parts of vinyltrimethoxysilane, 40 parts of absolute ethanol;
[0065] S2: Add 4 parts of pigments and fillers and 28 par...
