Problems solved by technology

Due to its elasticity, the elastic coating film is soft. Especially in hot summer weather, the surface of the coating film is even sticky and easily stained with dust. In addition, the dust dissolved in rainwater can also enter into the water through the water absorption of the coating film. The capillary pores of the coating film will cause permanent pollution to the coating film and greatly reduce the decorative effect of the coating film

Abstract

The invention discloses a photocatalytic long-acting stain-resistant elastic acrylate emulsion and a preparation method thereof. The photocatalytic long-acting stain-resistant elastic acrylate emulsion comprises the following raw materials: styrene, alkyl methacrylate, alkyl acrylate, a functional monomer, an initiator, an emulsifier, deionized water and ammonia water. The preparation method comprises the following steps: step a, preparing a backing material liquid; step b, preparing pre-emulsified liquid; step c, dropwise adding the pre-emulsified liquid to react; and step d, after finishingof the reaction, preserving heat, adjusting the pH value, and performing discharging. According to the invention, the reactive emulsifier is compounded with the phosphate salt, such that emulsifier migration and surface charges are reduced, and coating film adhesion resistance is improved. The compactness of a coating film can be effectively enhanced by reasonably matching the functional monomer and the photoinitiator, permanent damage caused by dust permeation is reduced, and the decorative service life of the coating film is prolonged.

Description

technical field [0001] The invention relates to a photocatalyzed long-term anti-fouling elastic acrylate emulsion and a preparation method thereof, belonging to the field of elastic coatings. Background technique [0002] With rich colors, simple construction, easy maintenance and renewal, light dead weight, non-toxic and tasteless, and high quality latex paint that can meet the requirements of protection and decoration, latex paint is becoming the leading building decoration material. Elastic latex paint is becoming more and more popular among users because it can cover capillary cracks on the wall and prevent carbonization of concrete. However, the disadvantage of poor stain resistance of elastic latex paint greatly reduces the decorativeness of latex paint. Restricted the further popularization and use of elastic latex. [0003] The elastic coating can extend or retract with the change of stress, and has suitable modulus and tensile strength when stretched, mainly elasti...
