Abstract

The invention discloses a preparation method of water-soluble acrylic resin for a reflection film. The water-soluble acrylic resin is prepared from the following raw materials in parts by weight: methyl methacrylate, ethyl acrylate, lauryl methacrylate, hydroxyethyl methylacrylate, acrylic acid, 1-ethyoxyl-2 propyl alcohol, dimethylethanolamine, deionized water and benzoperoxide through the following preparation steps of preparing a mixed solution A, feeding the mixed solution A into a reaction container to react, performing stirring, and continuously inputting nitrogen gas; stopping the nitrogen gas input, and raising and maintaining the temperature; preparing and dripping a mixed solution B, and after the dripping completion, maintaining the temperature; preparing and dripping a mixed solution C, and after the dripping completion, maintaining the temperature; preparing a mixed solution D, performing high-speed stirring dispersion, turning off a machine, and pouring out the materialsto obtain the transparent water-soluble acrylic resin for the reflection film. The water-soluble acrylic resin obtained by the invention has the advantages of good water resistance, intensity and elongation balance; and when the water-soluble acrylic resin is applied to the reflection film production, a reverse adhesion phenomenon and sudden and violent bubbling cannot easily occur in the coating,so that the appearance is full and flat.

Description

technical field [0001] The invention relates to an acrylic resin, in particular to a preparation method of a water-soluble acrylic resin for a reflective film. Background technique [0002] Reflective film is a retroreflective material that has been made into a thin film and can be directly applied. From the development history, the reflective film is mainly divided into four categories, from the earliest glass bead exposed reflective film to the glass bead embedded reflective film, and then to the later capsule reflective film and microprism reflective film. At present, the reflective film used for vehicle license plates and the reflective film used in some projects and advertisements are mainly glass beads embedded reflective film. [0003] The glass bead embedded reflective film is mainly composed of five layers: surface layer, glass bead layer, focusing layer, metal plating layer, and pressure-sensitive adhesive layer. Because of the special weather resistance and chemi...
