preparation example Construction

[0034] Correspondingly, an embodiment of the present invention provides a method for preparing a non-spray baking varnish imitation metal polypropylene material, comprising the following steps:

[0035] (1) Weigh the formula components

[0036] Weigh the polypropylene, polypropylene compatibilizer, nucleating agent, lubricant and antioxidant respectively according to the above-mentioned non-spray baking paint imitation metal polypropylene material formula;

[0037] (2) Prepare the mixture

[0038] Mix the polypropylene, polypropylene compatibilizer, nucleating agent, lubricant and antioxidant weighed in step (1) into a low-speed mixer and mix for 3 to 5 minutes, and mix well to obtain a mixture;

[0039] (3) Melt extrusion

[0040] The mixture obtained in step (2) is fed into the twin-screw extruder from the main feeding system, and then the composite metal powder is fed into the twin-screw extruder from the side feeding system, and melted and extruded and granulated to obta...

Embodiment 1

Abstract

The invention belongs to the technical field of modification of high polymer materials, and provides a spray-free baking varnish metal-like polypropylene material and a preparation method thereof. The spray-free baking varnish metal-like polypropylene material is prepared from the following raw materials in percentage by weight: 62-66% of polypropylene, 23-27% of composite metal powder, 8% of polypropylene compatilizer, 0.4% of nucleator, 2% of lubricant and 0.6% of antioxidant. The polypropylene is used as the substrate, composite metal powder for endowing the material with spray-free baking varnish metal-like properties is used as the main component, and the polypropylene compatilizer, nucleator, lubricant and antioxidant are proportionally used as the auxiliary materials; the proportions of appropriate resin raw material, various other assistants and the composite metal powder are selected to obtain the spray-free baking varnish metal-like polypropylene material. The spray-free baking varnish metal-like polypropylene material maintains excellent properties of the propylene, and can have the beautiful metal-like effect under the condition of no spraying of baking varnish, thereby overcoming the defect that the metal-like effect can only be obtained by spraying the baking varnish in the traditional polypropylene.

Description

technical field [0001] The invention belongs to the technical field of polymer material modification, and in particular relates to a spray-free stoving paint imitation metal polypropylene material and a preparation method thereof. Background technique [0002] Polypropylene (PP) is one of the general-purpose plastics. It has the advantages of low production cost, good comprehensive mechanical properties, non-toxicity, corrosion resistance, and easy recycling. It is widely used in chemical industry, chemical fiber, construction, packaging, automobile and other fields. [0003] Due to the rapid development of polypropylene modification technology in recent years, the application of polypropylene composite modified materials has become more and more extensive, and more polypropylene composite modified materials are directly used as exterior parts. Substituting steel" and "lightweight" purposes, there are often requirements for products not only to have excellent performance, bu...
