preparation example Construction

[0034] Concrete preparation method comprises the following steps:

[0035] (1) Weigh the raw materials according to the parts by weight of the prepared raw materials, add polypropylene, toughening agent, and skin touch modifier to the mixer, mix at 800-1500r / min for 3-15 minutes, and then add Compatibilizer and other additives, continue mixing at 800-1500r / min for 3-15 minutes;

[0036] (2) Add the material fully mixed in the step (1) into a twin-screw extruder for melting, add natural fibers and hollow glass microspheres at the side feeding port of the extruder, melt and mix under the protection of nitrogen, and finally pass through the double-screw extruder Extruded by a screw extruder, granulated and shaped to produce a low-density ultra-matt biomimetic polypropylene composite material.

[0037] If functional auxiliary agents such as scratch-resistant agents, antistatic agents, and colorants are added to the preparation components of the present invention to make the compo...

Abstract

The invention relates to the technical field of polymers, in particular to low-density super-matte bionic polypropylene composite and a preparation method thereof; the low-density super-matte bionic polypropylene composite is made from polypropylene, a flexibilizer, natural fibers, a skin tactility improver, glass beads, a compatibilizer, and other aids; the materials are mixed well and added into a parallel twin-screw extruder for melting, and the low-density super-matte bionic polypropylene composite is prepared via extruding and granulating. By adding the natural fibers, the glass beads, the compatibilizer, the skin tactility improver and the like during preparation, the prepared polypropylene composite is given the features such as ultralow gloss, low density, scratch resistance, good skin tactility and low shrinkage; in addition, the low-density super-matte bionic polypropylene composite retains the skin tactility, exhibits good rigidity and toughness, has a density of less than 1.02 g/cm<3>, and meets the development trend to light weight.

Description

technical field [0001] The invention relates to the technical field of polymers, in particular to a low-density ultra-matt biomimetic polypropylene composite material and a preparation method thereof Background technique [0002] The plastics used in automotive interior parts account for more than 50% of the plastics in the vehicle. The quality of automotive interior parts depends on the materials used. In the past, materials such as metal, wood and fiber textiles were mostly used for automotive interior parts, and the appearance and texture were not ideal. Thermoplastics have a series of advantages such as easy molding, good toughness, high strength, good heat insulation, light texture, corrosion resistance and low cost, and have replaced traditional steel materials in the application of automotive interior parts. [0003] In the prior art, mineral-filled polypropylene has the characteristics of low density, excellent mechanical properties, corrosion resistance, environme...
