Abstract

The invention discloses a method for preparing an acrylic ester type resin with toughness and hardness at a low temperature. The method comprises the following steps: uniformly mixing an acrylic acidresin, a toughening agent, a cold-resistant agent, a cross-linking agent, a coupling agent, an antioxidant, a catalyst and a plasticizer in parts by weight, drying the raw materials, blending, mixingand stirring, melting, performing cooling and drawing, and cutting into granules, wherein the procedure of melting is carried out in a double-screw extruder particularly; the pressure of the head of the double-screw extruder is not less than 1MPa; the rotation speed of a screw rod is 120rpm; the exhaust vacuum degree is not greater than 0.05; the temperature of three sections of cylinders is within 150-200 DEG C; the temperatures of the three sections of the cylinders are respectively 150 DEG C, 180 DEG C and 200 DEG C. The obtained acrylic ester type resin can be normally used in extremely cold areas, and the service life of the resin can be prolonged.

Description

technical field [0001] The invention relates to a method for preparing an acrylic resin, in particular to a method for preparing an acrylic resin with toughness and hardness at low temperature. Background technique [0002] Acrylic resin, English name: poly (1-carboxyethylene) or Poly (acrylic acid). It is a resin made by copolymerization of acrylates, methacrylates and other ethylenic monomers. By choosing different resin structures, different formulations, production processes and solvents, it can be synthesized with different types, different properties and different applications. According to the difference of structure and film-forming mechanism, acrylic resin can be divided into thermoplastic acrylic resin and thermosetting acrylic resin. [0003] Molded products of acrylic resins are excellent in transparency, beautiful in appearance, and weather-resistant, and are widely used in electrical parts, vehicle parts, optical parts, decorations, billboards, and the like. ...
