[0034] a. Add 10kg of water into the reaction kettle, heat it to 80°C, add 55kg of No. 56 semi-refined paraffin wax, keep warm until the paraffin is completely melted, then quickly add 1kg of GR-200 emulsifier, and continue the heat preservation reaction for 40 minutes;

[0035] b. Then add 9kg of acrylic acid emulsion, fully stir at a speed of 200/min, and react for 30 minutes;

[0036] c, add mass fraction again and be 6% sodium benzoate 5kg, be fully stirred at the rotating speed of 200/min with the rotating speed, react for 20 minutes;

[0037] d. Add 20kg of water and dilute at a speed of 100/min;

[0038] e. Continue to heat the reaction. When the temperature of the mixed solution rises to 90°C, stir at a speed of 200/min. After 70 minutes of constant temperature reaction, add an appropriate amount of caustic soda solution with a mass fraction of 30%, and adjust the pH value to 9 ;

[0039] f. After the mixed solution turns white and viscous, disperse it at a high speed of 1200 rpm for 30 minutes to prepare the novel coating of the present invention.

[0040] Embodiment 3, a kind of novel coating, gets the following components by weight: paraffin: 50kg; Mass fraction is 6% sodium benzoate: 5.5kg; Acrylic acid emulsion: 8.5kg; Emulsifier: 1.5kg; Mass fraction is 30% caustic soda solution; water: 34kg. Its preparation method specifically comprises the following steps:

[0041] a. Add 12kg of water to the reaction kettle, heat it to 80°C, add 50kg of No. 56 semi-refined paraffin wax, keep warm until the paraffin is completely melted, then quickly add 1.5kg of GR-200 emulsifier, and continue the heat preservation reaction for 35 minutes;

[0042] b. Then add 8.5kg acrylic acid emulsion, 200 rpm, fully stir, and react for 25 minutes;

[0043] c, then add 5.5kg of sodium benzoate with a mass fraction of 6%, fully stir, and react for 25 minutes;

[0044] d. Then add 22kg of water to dilute; 100 rpm to dilute and stir

[0045] e. Continue the heating reaction. When the temperature of the mixed solution rises to 90°C, after 65 minutes of reaction at a constant temperature of 200 rpm, add an appropriate amount of caustic soda solution with a mass fraction of 30%, and adjust the pH value to 9;

[0046] f. After the mixed solution turns white and viscous, disperse it at a high speed of 1200 rpm for 30 minutes to prepare the novel coating of the present invention.

[0047] The novel coating that above-mentioned three embodiments make is colorless and tasteless, environmental protection, raw material cost is low, energy consumption is low, process step is simple, produces 1 ton of novel coating of the present invention, and its cost is only 3000 yuan, is present There are 1/5 of ordinary waterproof paint. As a waterproof coating, it is applied to the exterior walls of newly-built buildings in the North Garden, Longfeng Garden and Yulong Courtyard of Liangping County, Chongqing City. The waterproof effect is very ideal, and there will be no infiltration, which fully meets the acceptance standards of commercial houses; and Cost accounting is only 0.80 yuan/m 2 , which is 1/5 of the existing common external wall waterproof material. Simultaneously it is also applied to municipal engineering as an anti-adhesive agent, and the surface of public facilities such as building walls and utility poles around the people's square in Liangping County, Chongqing City is coated with a layer of novel coating of the present invention. After scribbling and posting various advertisements, sanitation workers only need to delineate the area to be removed with a knife when removing the "psoriasis" of the scribbling and pasting, and then gently pull it to form a sheet. The film is torn off, and then the paint can be painted again on the torn-off place. Compared with the existing method of removing "urban psoriasis", the removal efficiency is more than 5 times that of the existing method, and it will not cause any damage to public facilities. It is a good medicine for treating "urban psoriasis".
