Abstract

The invention belongs to the field of polymer materials and provides a weather-resistant matte-type high-strength PA6 and ASA alloy material and a preparation method thereof. The PA6 and ASA alloy material comprises the following components: 40%-70% of PA6, 10%-25% of ASA, 10%-20% of carbon fiber, 8%-12% of nano-montmorillonite, 1%-5% of a compatibilizer, namely, ABS grafted maleic anhydride, 1%-5% of a toughener, namely, POE grafted maleic anhydride, 0.1%-1% of an antioxidant, 0.1%-1% of a lubricant and 1%-2.5% of carbon black. By adopting the PA6 and ASA alloys, an incompatible system of the PA6 and ASA alloys in a sea-island structure forms slightly rough surfaces of the surface and thus matte delustering-grade surface is formed, the nano-montmorillonite is added to further homogenize the distribution of the slightly rough surfaces and meanwhile, carbon fiber is added to achieve a reinforcement effect, the compatibilizer is added so that the phenomenon that two resins are severely separated and the material is layered and peeled are not caused, and carbon black is added such that the UV aging resistance of the material can be effectively improved, therefore, the weather-resistant matte-type high-strength PA6 and ASA alloy material disclosed by the invention is a matte-grade interior / exterior material which has very excellent overall performance.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a method for preparing weather-resistant matte-grade high-strength PA6 and ASA alloy materials. Background technique [0002] With the improvement of people's quality of life, the aesthetic requirements for cars and daily necessities are getting higher and higher, and the application of matte black in high-end cars and high-end homes is also increasing. Usually, matte grade PC / ABS alloys are used in the market. Matte exterior decoration materials, but PC / ABS has disadvantages such as easy stress cracking, poor weather resistance, poor wear resistance and scratch resistance, and general strength. Therefore, for the expansion of the application of matte exterior materials in the market, a single PC / ABS has been It cannot meet the various needs of the market, and it is urgent to develop a corresponding material with excellent comprehensive performance that can ...
