Problems solved by technology

[0004] However, the existing aesthetic resin technical solutions have certain defects in weather resistance. These solutions have no problem in fields that do not require high weather resistance, but when the final product has high requirements for weather resistance, it will greatly limit The application of aesthetic resins, especially in the automotive field, has very strict weather resistance requirements for both interior and exterior parts, and it is difficult for ordinary aesthetic resins to meet the requirements

Abstract

The invention relates to a highly weather-resistant aesthetic resin. The highly weather-resistant aesthetic resin is prepared from the following components in parts by weight: 100 parts of a matrix resin, 0.1-5 parts of effect pigments, 1-10 parts of a weather-resistant modifier, 0.3-2.0 parts of a lubricating agent and 0.1-1.0 part of an antioxidant. The invention also provides a method for preparing the highly weather-resistant aesthetic resin. The invention has the advantages that the aesthetic resin prepared by the invention has excellent appearance, does not have any flow trace or weld line during injection molding, overcomes the defect in the prior art that the aesthetic resin is insufficient in weather resistance, greatly widens the application field and range of replacing spray with the aesthetic resin, really realizes a green, energy-saving and environmental-friendly spraying-free solution, and can be widely applied to the fields with particularly high weather resistance requirements, such as automobiles, household appliances, consumer electronics and the like.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a highly weather-resistant aesthetic resin and a preparation method thereof. Background technique [0002] As environmental issues have attracted more and more attention, the spray-free aesthetic resin that can replace spray paint has shown unprecedented competitiveness, which has attracted the attention of many enterprises and people. Spray-free aesthetic resins are usually achieved by adding metal pigments, pearlescent pigments, glass flakes and other effect pigments with special colors and appearances to high-gloss resin materials. Common plastics that can be used to prepare spray-free aesthetic resins include PP, ABS, PMMA, PMMA / ABS, PC, PC / ABS, ASA, polyester, PS, etc. [0003] Spray-free aesthetic resin can help customers cope with diversified and differentiated market demands. Compared with spray resin, it can reduce the production process, improve production ef...
