Abstract

The invention relates to a modified material of a color profile material, in particular to an ASA (acrylonitrile-styrene-acrylate) modified material, which solves the problems that: because of the scratches and the strias, the chromatic aberration and matt surface are always generated during the preparation of color profile material by ASA resin. According to the mass ratio, the ASA modified material comprises: 40 to 60 portions ASA resin, 0.15 to 0.25 portions light stabilizer, 0.15 to 0.25 portion ultraviolet adsorbent, 4 to 5 portions dispersing agent, 4 to 5 portions lubricant, 5 to 15 portions reinforcer, 5 to 15 portions upgrading nucleating agent, 0.1 to 0.3 portions coupling agent and 1 to 5 portions color pigment. The modified material of a color profile material has the advantages that: based on the performance of good color pigment, rich colors and favorable weatherability of the prior art, the ASA modified material prepared has higher toughness, rigidity and intensity; meanwhile, ASA modified material can be exposed in the conditions with ultraviolet, wet air, rain, lighting and ozone for long time; furthermore, the color profile material prepared has uniform colors, favorable glossiness of the surface without chromatic aberration.

Description

technical field [0001] The invention relates to a modified material for colored profiles, in particular to an ASA modified material. Background technique [0002] With the development of the market economy and the acceleration of the urbanization process, the domestic real estate industry has ushered in unprecedented opportunities for development. As an environmentally friendly building material, plastic window profiles have many advantages such as elegant appearance, aging resistance, corrosion resistance, sound insulation, heat insulation, and energy saving, and have a broad market prospect. With the improvement of people's living standards, the pursuit of colorful personalized demand is becoming more and more intense. The earliest colored plastic windows introduced in China were PVC and PVC co-extruded profiles. After time testing, this profile has poor weather resistance. In recent years, with the continuous advancement of technology, a new generation of colored plasti...
