Problems solved by technology

[0004] Although this gasoline-resistant toughened PMMA resin and its preparation method have improved the overall oil resistance by adding a gasoline-resistant modifier, it can be widely used in automobile rearview mirrors, B-pillars and grilles, etc. There are requirements for paint-free parts, but this kind of PMMA resin does not have a frosted effect after being prepared as a whole. When it is applied to LED lampshades, etc., the light is relatively strong, which affects the overall aesthetic effect

Abstract

The invention discloses a PMMA (Polymethyl Methacrylate) frosted resin and a preparation method of the PMMA frosted resin, and aims at providing a formula for the PMMA frosted resin having a better frosting effect and the preparation method of the PMMA frosted resin. The key point of the technical scheme is as follows: the PMMA frosted resin comprises the following components by mass: 80-96 partsof polymethyl methacrylate, 4-20 parts of organosilicone microsphere or other surface compatibility treated glass microspheres, 0.1-1 part of a dispersing agent, and 1-2 parts of a coupling agent. Thepreparation method comprises the following steps: S1: respectively weighing the corresponding various components according to the proportion; S2: stirring the various materials in a high-speed stirrer for 10-20 minutes; and S3: extruding and forming the well mixed materials in a twin-screw extruder.

Description

technical field [0001] The invention relates to the field of modified resins, in particular to a PMMA frosted resin and a preparation method thereof. Background technique [0002] Polymethyl methacrylate, polymers obtained by polymerization of acrylic acid and its esters are collectively referred to as acrylic resins, and the corresponding plastics are collectively referred to as polyacrylic plastics, among which polymethyl methacrylate is the most widely used. The abbreviated code name of polymethyl methacrylate is PMMA, commonly known as plexiglass, which is by far the most excellent and relatively affordable variety of synthetic transparent materials. [0003] At present, the Chinese patent with the publication number CN105419203A discloses a gasoline-resistant toughened PMMA resin and a preparation method thereof, which includes the following formulation by weight: 40-80 parts of PMMA, 5-30 parts of gasoline-resistant 15-30 parts of toughening agent, 0.1-1 part of antio...
