[0031] Working principle: Talcum powder and zeolite are put into the feeding hopper 4. The servo motor 2 drives the first rotating rod 23 and the spiral blade 22 to rotate, so that the mixture of talcum powder and zeolite moves in the conveying pipe 5 and is further mixed. Then, the talcum powder and zeolite fall from the discharge port 21 into the gap between the fixed frame 7 and the grinding wheel 26. The first pulley 20 rotates with the first rotating rod 23 and transmits the power through the first belt 10 to the second pulley 11 and the second rotating rod 3. The second rotating rod 3 drives the grinding wheel 26 to rotate, grinding and dispersing the mixture. The ground material enters the semi-cylindrical barrel 18 from the feeding port 36. The third pulley 14 rotates with the second rotating rod 3 and transmits the power through the second belt 16 to the fourth pulley 15 and the third rotating rod 17. The third rotating rod 17 drives the stirring rod 38 and the turning rod 39 to rotate in the semi-cylindrical barrel 18 to stir the material. Water-based resin, additives and pigments are added from the feeding frame 33. The water-based resin, additives and pigments flow downward through the gap between the guiding inclined plate 34 and the feeding frame 33, and flow along the guiding arc 35 of the L-shaped guiding plate 6 to the feeding port 36, and finally enter the semi-cylindrical barrel 18, forming the original pulp under the stirring action. While the disc 9 rotates with the second rotating rod 3, the triangular wedge 12 on the disc 9 contacts the lever 13 and pushes the lever 13 to move along its radial direction, and the spring 30 is compressed. When the triangular wedge 12 is separated from the lever 13, under the rebound action of the spring 30, the lever 13 moves back. Each triangular wedge 12 on the disc 9 contacts the lever 13 in turn, enabling the lever 13 to reciprocate, so that the steel wire brush on the lever 13 rubs the surface of the grinding wheel 26, preventing the material from getting stuck on the surface of the grinding wheel 26. By opening the solenoid valve 24, water is sprayed from the spray holes of the water spray pipe 32 onto the grinding wheel 26 to wash the grinding wheel 26, and the water flows from the feeding port 36 to the semi-cylindrical barrel 18, and after continuous stirring and mixing, an environmentally friendly self-cleaning modified coating is obtained. Opening the discharge valve 19 can discharge the coating.

[0032] A preparation method of an environmentally friendly self-cleaning modified coating, comprising the following steps:

[0033] Step (1): Add talcum powder and zeolite to the middle feeding hopper 4, where the mass ratio of talcum powder to zeolite is (1 - 3):1;

[0034] Step (2): Mix the talcum powder and zeolite evenly to obtain a mixture;

[0035] Step (3): Grind and disperse the mixed material using the grinding wheel 26:

[0036] Step (4): Add 0.1 - 0.3 parts by weight of acrylic resin, 0.2 - 0.4 parts by weight of leveling agent, 0.1 - 0.5 parts by weight of dispersant, 0.05 - 0.1 parts by weight of anti-settling agent and 0.2 - 0.4 parts by weight of pigment to the ground material, and stir in the semi-circular barrel 18 for 15 - 20 min to obtain the original pulp;

[0037] Step (5): Add an appropriate amount of water to the original pulp for modulation to obtain the required slurry;

[0038] Step (6): Package the modulated slurry and store it in a cool and dry place for future use.

[0039] Through actual application tests, the environment-friendly self-cleaning modified coating of the present utility model shows excellent effects in terms of environmental protection performance, self-cleaning performance and weather resistance, etc., and has a good market prospect.
