Abstract

The invention discloses a transparent gasoline-resistant PMMA alloy material and a preparation method thereof, which are characterized by comprising the following components in percentage by weight: 43.3 to 75.3 percent of polymethyl methacrylate, 15 to 30 percent of SAN-coated crosslinked acrylic rubber, 3 to 5 percent of styrene-anhydrous maleic anhydride polymer, 5 to 30 percent of polyamide, 0.2 percent of phenolic antioxidant, 0.2 percent of phosphate antioxidant, 0.1 percent of thioester antioxidant, 0.3 percent of benzotriazole ultraviolet absorber, 0.6 percent of hindered amine light stabilizer and 0.3 percent of pentaerythritol tetrastearate. The transparent gasoline-resistant PMMA alloy material and the preparation method thereof adopt SAN-coated acrylic rubber to toughen PMMA, the acrylic rubber has excellent weather resistance, and the compatibility of the acrylic rubber and PMMA can be improved by adopting SAN coating.

Description

technical field [0001] The invention belongs to the technical field of alloy materials, in particular to a transparent gasoline-resistant PMMA alloy material and a preparation method thereof. Background technique [0002] Polymethyl methacrylate (PMMA, commonly known as plexiglass, acrylic or acrylic), has crystal-like transparency, with a light transmittance of over 92%, and has a good color development effect when dyed with dyes. In addition, PMMA has excellent weather resistance, high surface hardness and surface gloss, and good high temperature performance. PMMA is widely used in aviation, automobile, electronics, medical, chemical, building materials, sanitary ware and advertising signs and other industries. [0003] However, the common PMMA resin is easy to crack and brittle due to its low extensibility, which limits its further application. Contents of the invention [0004] Aiming at the problems existing in the prior art, the object of the present invention is t...
