Abstract

The invention relates to the technical field of ASA and PC composite materials, and discloses an ASA / AS and modified PC co-extrusion material, a preparation method and application thereof. The co-extrusion material comprises an outer-layer material and an inner-layer material, wherein the outer-layer material is an ASA / AS blended material and the inner-layer material is modified PC material. The ASA / AS blended material is prepared from the following components in parts by weight: 20-80 parts of ASA resin, 20-80 parts of AS resin, 10-40 parts of a filling material, 3-8 parts of a compatilizer, 0.2-0.6 part of a light stabilizer and 0.2-1 part of an anti-oxidant. The modified PC material is prepared from the following components in parts by weight: 70-100 parts of PC resin, 10-40 parts of a filling material, 2-15 parts of a lubricant, 0.1-0.8 part of a dispersant and 0.2-1 part of an anti-oxidant. The invention also discloses the application of the ASA / AS and modified PC co-extrusion material as a radome. The radome prepared from the co-extrusion material has double-layer structure, and compared with conventional radomes, and the radome has the characteristics of dimension stability, impact resistance, solvent resistance and weatherability.

Description

technical field [0001] The invention relates to the technical field of composite materials of ASA and PC, in particular to a co-extrusion material of ASA / AS and modified PC, a preparation method and application thereof. Background technique [0002] Acrylonitrile-acrylate-styrene resin (ASA) is an impact-modified resin polymerized from styrene, acrylonitrile and acrylate terpolymer. Since ASA resin introduces acrylic rubber without double bonds, only light with a wavelength of less than 300nm will have an aging effect on it, so it has better weather resistance. Its dyed products do not need coating protection, even if they are exposed to It can also maintain the stability of mechanical properties and appearance color under ultraviolet rays, moisture, high temperature and cold. [0003] The impact toughness of polycarbonate (PC) is one of the best among thermoplastic resins. It has good dimensional stability and good heat resistance. It can be used for a long time at -60-120...
