Abstract

The invention discloses novel paint, which is prepared from paraffins, sodium benzoate, acrylic emulsion, emulgator, caustic soda flakes and water. Non-toxic raw materials are adopted, and the obtained product has a lower cost and is odorless and colorless. The novel paint is prepared by the process steps of heating, stirring, dispersing and the like, and the whole process step is simple, has low energy consumption, and saves the cost. The preparation process cannot generate toxic and harmful substances and is environmentally-friendly. The novel paint is applied to the water-proof fields of exterior walls, or interior walls and the like, only a simple painting mode is adopted to form a layer of thin water-proof membrane on the exterior walls or the interior walls, and the water-proof performance is good. In addition, the novel paint can also be applied to the bonding-proof field, such as the field of municipal treatment of 'city psoriasis', the labor strength of sanitation workers is greatly reduced, meanwhile, the removal efficiency is greatly increased, and the difficult problem 'city psoriasis' is easily solved.

[0027] a. Add 12kg of water to the reaction kettle, heat it to 80°C, add 45kg of No. 56 semi-refined paraffin wax, keep warm until the paraffin is completely melted, then quickly add 2kg of GR-200 emulsifier, and continue the heat preservation reaction for 30 minutes;
[0028] b. Then add 8kg of acrylic acid emulsion, fully stir at a speed of 200/min, and react for 20 minutes;
[0029] c, then add 6kg of sodium benzoate with a mass fraction of 6%, fully stir at a speed of 200/min, and react for 30 minutes;
[0030] d. Add 25kg of water again, and stir and dilute at a speed of 100/min;
[0031] 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 constant temperature reaction for 60 minutes, add an appropriate amount of caustic soda solution with a mass fraction of 30%, and adjust the pH value to 9 ;
[0032] 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.

Example Embodiment

[0033] Embodiment 2, a kind of novel coating, gets the following components by weight: paraffin: 55kg; Mass fraction is 6% sodium benzoate: 5kg; Acrylic acid emulsion: 9kg; Emulsifier: 1kg; Mass fraction is 30% caustic soda Solution; water: 30kg. Its preparation method specifically comprises the following steps:
[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;

[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".
