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.

Description

technical field [0001] The invention relates to a novel material and its preparation method and application, in particular to a coating and its preparation method, as well as its application in the field of waterproofing and the field of adhesive bonding technology. Background technique [0002] Paint is coated on the surface of the object to be protected or decorated, and can form a continuous film firmly attached to the object to be coated, usually based on resin, or oil, or emulsion, with or without adding pigments, fillers, and adding corresponding Additives, viscous liquids prepared with organic solvents or water. In order to adapt to the needs of the modern architectural field, etc., the existing coatings are various, each with its own advantages and disadvantages. But the common denominator is that they are expensive. For example, if it is used in fields such as building exterior wall waterproofing, the construction cost will be greatly increased. [0003] In addit...
