Embodiment 1

[0030] Add 65 parts of polypropylene, 5 parts of polypropylene wax, 20 parts of mineral powder, 10 parts of modified straw powder, 0.2 parts of dispersant, 0.2 parts of lubricant, and 0.5 parts of antioxidant into the high-mixer and mix for 10 minutes; then mix The homogeneous material is mixed and extruded in a twin-screw extruder, wherein the extrusion temperatures of the three stages of the twin-screw extruder are 160°C, 165°C, and 170°C, respectively. The test results are shown in Table 1.

Embodiment 2

[0032] Add 70 parts of polypropylene, 5 parts of polypropylene wax, 15 parts of mineral powder, 8 parts of modified straw powder, 0.2 parts of dispersant, 0.2 parts of lubricant, and 0.5 parts of antioxidant into the high-mixer and mix for 10 minutes; then mix well The materials were mixed and extruded in a twin-screw extruder, wherein the extrusion temperatures of the three sections of the twin-screw extruder were 155°C, 160°C, and 165°C, respectively. The test results are shown in Table 1.

Embodiment 3

[0034] Add 80 parts of polypropylene, 5 parts of polypropylene wax, 10 parts of mineral powder, 5 parts of modified straw powder, 0.2 parts of dispersant, 0.2 parts of lubricant, and 0.5 parts of antioxidant into the high mixer and mix for 10 minutes; then mix well The materials were mixed and extruded in a twin-screw extruder, wherein the extrusion temperatures of the three sections of the twin-screw extruder were 150°C, 155°C, and 160°C, respectively.

Abstract

The invention discloses an environment-friendly polypropylene composite board and a preparation method thereof. The environment-friendly polypropylene composite board is prepared from 65-80 parts of polypropylene, 5 parts of polypropylene wax, 10-20 parts of mineral powder, 5-10 parts of modified straw powder, 0.2 part of a dispersing agent, 0.2 part of a lubricating agent and 0.5 part of an antioxidant. According to the natural fiber filler with the treated surface, straw powder is modified by a surface graft polymerization mode, the effect is obvious, the interface effect of the filler and matrix resin can be effectively enhanced, and the mechanical property of the composite material is improved. The matrix resin used in the invention is excellent in comprehensive performance and strongin weatherability, does not need to additionally add any adhesive in the production molding process, and has good environmental protection performance.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to an environment-friendly polypropylene composite board and a preparation method thereof. Background technique [0002] As a composite material that is healthy, environmentally friendly, cheap, and comfortable to use, wood-plastic material has been widely welcomed by the market since it came out, and has become a hot product in the interior decoration material market. And because of its rising sales, leading to a shortage of high-quality raw materials. Among the wood-plastic composite materials, the cork-based composite material has the best comprehensive performance, and has the advantages of light weight, moisture resistance, and wear resistance. However, due to the extremely limited number of cork oak, the composite board of cork material has always been at a relatively high price. . [0003] Seeking natural fibers that can replace cork materials is a relatively ex...
