Low-odor and high-performance plant fiber reinforced regenerated polypropylene composite material and preparation method thereof

Abstract

The invention discloses a low-odor and high-performance plant fiber reinforced regenerated polypropylene composite material and a preparation method thereof. The low-odor and high-performance plant fiber reinforced regenerated polypropylene composite material comprises the following raw materials in parts by weight: 34.5-69.5 parts of polypropylene regenerated material; 20 to 50 parts of plant fiber; 5-10 parts of an elastomer; 0-5 parts of odor improving master batch; 1-3 parts of a compatilizer; 0.5 to 2 parts of a coupling agent; 0-1 part of an antioxidant; 0-3 parts of other auxiliary agents; the method has the advantages that the odor improving master batch used in the method combines physical adsorption and chemical odor removal, namely, the characteristic of high specific surface area of activated carbon can quickly and effectively adsorb odor molecules, and meanwhile, nano titanium dioxide can effectively decompose small organic molecules emitted by a material system under the catalytic action of visible light, so that the odor improving master batch can be used for improving the odor. And the activated carbon and the porous activated carbon with a physical adsorption function play a synergistic effect to jointly improve the odor emission performance of a material system.

Description

technical field [0001] The invention belongs to the technical field of polymer modification and processing, and relates to a low-odor, high-performance, plant fiber-reinforced recycled polypropylene composite material and a preparation method thereof. Background technique [0002] With the continuous emission of carbon dioxide and the increase of greenhouse gases around the world, the problem of climate warming is becoming more and more serious, which has threatened the life system of the earth. my country took the lead in proposing the national strategy of peaking carbon emissions by 2030 and achieving carbon neutrality by 2060. Therefore, vigorously developing a low-carbon, green and circular industrial economy has become one of the important contents of China's economic transformation. In the process of achieving the goal of carbon peaking and carbon neutrality, the traditional manufacturing automobile industry needs to change its existing production mode, and the car ma...

Problems solved by technology

[0005] Recycled polypropylene plastic, also known as polypropylene reclaimed material, due to its recycling characteristics, when it is re-produced, extruded, and used for injection molding, it will easily produce unpleasant odors, and at the same time, some mechanical properties will also be lost. This will bring inconvenience to the application and promotion of automotive interior parts that have certain requirements for odor and mechanical properties
