Abstract

The invention discloses a special pressure-sensitive adhesive for prism film on the surface of cement and a preparation method thereof. The A component includes the following raw material components in parts by mass: 20-40 parts of acrylate polymer, 100-180 parts of ethanol, 1-3 parts of calcium bicarbonate, 5-8 parts of polyallylamine and 1-6 parts of additives; B component includes the following raw material components in parts by weight: 35-48 parts of bisphenol F type epoxy resin, 5- 10 parts Epoxy E‑51. The preparation method of the present invention comprises the steps of stirring and mixing component A, and then ultrasonically dispersing; mixing component B to obtain component B; and then separately encapsulating. The pressure-sensitive adhesive prepared by the invention has excellent cohesive strength, excellent cohesiveness to the special surface of cement, and good water resistance.

Description

technical field [0001] The invention belongs to the technical field of reflective film adhesives, and in particular relates to a pressure-sensitive adhesive specially used for prism films on cement surfaces and a preparation method thereof. Background technique [0002] Pressure-sensitive adhesive is a kind of pressure-sensitive adhesive, which has the characteristics of strong adhesion, no pollution, and convenient use. For example, when bonding reflective film and road signs, the pressure-sensitive adhesive can well attach the reflective film to the road signs, and it is not easy to fall off after long-term use, which plays a good bonding role. [0003] With the development of society, there are more and more types of reflective films today. In addition to ordinary bead-embedded reflective films and sealed microcapsule reflective films, there are now prism films. Prism films have excellent reflective properties, so more and more people's attention. [0004] Because of th...
