Abstract

The invention discloses a cloud rhyolitic plastic product processing method taking ABS as a base material. Plastic compositions comprises 56-71% ABS plastic grains, 10-15% of cloud color masterbatch,10-20% of modified glass fiber, 5-9% of compatilizer, 1-2% of flexibilizer, 0.5-1.5% of lubricant and 0.2-0.5% of antioxidant. Accordingly, a composite material with rhyolitic color is prepared through melting coextrusion, rhyolitic plastic product processing is achieved by means of an injection molding process, and the plastic product has the gorgeous appearance. By adding the modified glass fiber and ABS-g-MAH in the composite material, interface adhesion between two phases of ABS and cloud color masterbatch and mechanical property of the composite material are improved, and the prepared plastic product has cloud rhyolitic and keeps high mechanical strength.

Description

technical field [0001] The invention relates to a method for processing a cloud flow pattern plastic product with ABS as a base material, and belongs to the technical field of plastic product processing. Background technique [0002] In order to obtain gorgeous, colorful, and diverse appearances, plastic product manufacturers usually use the method of spraying paint on plastic substrates to achieve bright, beautiful, and special-effect appearances. However, the spraying process has disadvantages such as complicated process, high cost, polluting the environment, endangering the health of workers, and being difficult to recycle. It is precisely because of the many disadvantages of the spraying process that the preparation process of spray-free plastic products is gradually welcomed by plastic product manufacturers. With the continuous improvement of production equipment and process levels, spray-free multi-material mixed injection molding has become one of the main preparation...
