Abstract

The invention discloses a water-based acrylate adhesive for reflective coatings and a preparation method thereof. The water-based acrylate adhesive comprises the raw materials in parts by weight: 8-10 parts of perfluoroalkyl phosphate amine salt, 0.5-1.5 parts of heterogeneous tridecyl alcohol polyoxyethylene (40) ether, 6-7 parts of diacetone acrylamide, 3-4 parts of adipic dihydrazide, 1-2 parts of vinyl-containing functional silicon oil, 145-155 parts of ethyl acrylate, 30-40 part of methyl methacrylate, 2-4 parts of acrylic acid, 1-1.4 parts of ammonium persulfate and 280 parts of deionized water. An emulsion is obtained through semicontinuous emulsion polymerization; the adhesive and the inorganic material are in high binding firmness, and the adhesive is abrasion-proof, weather-resistant, stain-proof and high in film-forming transparency.

Description

technical field [0001] The invention relates to an adhesive for reflective paint, in particular to a water-based acrylate adhesive for reflective paint and a preparation method thereof. Background technique [0002] The road surface markings of expressways generally have reflective functions, so as to provide safety protection for vehicles driving on these highways at night. This type of sign is made by coating the road surface with reflective paint. Reflective coatings can be divided into two types: water-based and solvent-based. With the enhancement of people's awareness of environmental protection and safety and the implementation of relevant national policies and regulations, the use of solvent-based reflective coatings is becoming less and less, and water-based reflective coatings with environmental protection characteristics are gradually gaining popularity. attention and application. [0003] Water-based reflective coatings are generally composed of reflective mater...
