Problems solved by technology

However, the above-mentioned technical solutions often have defects such as insufficient impact performance, low rigidity, and weather resistance that cannot meet the requirements of automotive exterior decoration. PMMA / ASA resin has excellent weather resistance. At the same time, by adjusting the ratio of PMMA and ASA resin, the introduction Toughener and compatibilizer, can prepare high-gloss spray-free resin alloy with excellent physical and mechanical properties

Abstract

The invention relates to a high-gloss spray-coating-free PMMA / ASA alloy resin composition and a preparation method thereof. The PMMA / ASA alloy resin composition comprises the following components, by weight: 35-60 parts of PMMA resin, 30-60 parts of ASA resin, 5-20 parts of a toughening agent, 1-5 parts of a compatilizer, 0.5-2.0 parts of a black master batch and 0.6-1.5 parts of a processing additive. The preparation method includes the following steps: weighing the components according to the weight parts, mixing the components uniformly to prepare a premix, feeding the premix into a double-screw extruder, performing melt extrusion and performing cooling granulation to obtain the target product. Compared with materials in the prior art, the PMMA / ASA alloy resin composition is excellent in mechanical performance, is high in glossiness, is simple in preparation process, is prepared from easy-to-obtain raw materials and is low in cost.

Description

technical field [0001] The invention relates to an alloy resin composition and a preparation method thereof, in particular to a high-gloss spray-free PMMA / ASA alloy resin composition and a preparation method thereof. Background technique [0002] Today's automobile industry is developing rapidly, and automobiles are the most common and important type of modern transportation. The use of plastic materials to replace various non-ferrous metals and alloy steels in the automotive field is becoming more and more extensive. The average plastic used in each car in developed countries such as Japan, the United States and Germany has exceeded 100 kilograms, accounting for 8% of the total weight of the car on average. , The average amount of plastic used in each car in China is 70 kg, accounting for an average of 6% of the total weight of the car. The application of plastic materials in the automotive field makes the design of auto parts more flexible, and at the same time reduces th...
