Environment-friendly low-ammonia-nitrogen foaming coating

Abstract

The invention discloses an environment-friendly low-ammonia-nitrogen foaming coating, and belongs to the technical field of full-shading roller shutter fabric coatings. The coating comprises the following components in percentage by mass: 3 to 12 percent of a foam stabilizer, 0.1 to 5 percent of sodium hydroxide or potassium hydroxide solution or organic amine, 0.1 to 2 percent of a crosslinking agent or a coupling agent, 25 to 60 percent of an adhesive, 5 to 25 percent of titanium dioxide, 5 to 25 percent of kaolin, 0.1 to 3 percent of a pH regulator and 0.1 to 3 percent of an initiator. Theammonia nitrogen substances are reduced, thus ammonia water smell with strong irritation in the production process is reduced, an operator can use the coating conveniently, the ammonia nitrogen substances in discharged sewage are reduced, the sewage treatment cost is reduced, the ammonia nitrogen substances are reduced from the source, and the problems that in the production process in the prior art, the ammonia water smell is very heavy, ammonia water is a substance with heavy pungent smell, and an operator is difficult to adapt to the environment.

Description

technical field [0001] The invention relates to the technical field of foam coatings, in particular to an environment-friendly low ammonia nitrogen foam coating. Background technique [0002] In the field of full shading foam coating, the system currently used is mainly acrylic emulsion system, with a certain amount of titanium dioxide, kaolin, and a certain amount of foam stabilizer (ammonium stearate), foaming agent (emulsifier) ) and ammonia water, usually requiring a pH greater than 9.5. [0003] Therefore, the addition ratio of ammonia water is very high, which usually causes two problems, [0004] (1) During the production process, the smell of ammonia water is very strong. Ammonia water is a substance with a strong irritating taste, and it is difficult for operators to adapt to this environment; [0005] (2) The final discharged sewage contains a large amount of ammonia nitrogen substances, and the cost of sewage treatment is very high.
