Problems solved by technology

[0004] The rapid development of polypropylene modification technology makes it more and more widely used in automotive interior and exterior decoration. However, due to the influence of monomer, catalyst, polymerization process and degradation in the synthesis process of polypropylene, polypropylene resin and its products are still There are varying degrees of release of volatile organic compounds (VOC) to pollute the environment and endanger people's health, and are subject to many restrictions in actual use

preparation example Construction

[0034] (2) Preparation of composite materials:

[0035] According to the weight ratio in the formula, polypropylene, odor absorbing material, inorganic mineral powder, toughening agent and processing aid are evenly mixed, and then melted in a twin-screw extruder with a length-to-diameter ratio of 35-50:1. Mix and disperse, then add the heat stabilizer masterbatch from the side feed of the twin-screw extruder, plasticize at a temperature of 170-210°C, and then extrude and granulate through the twin-screw to obtain a low-odor modified polymer Acrylic composite.

Abstract

Belonging to the technical field of polymer composite materials, the invention in particular relates to a low-odor modified polypropylene composite material and a preparation method thereof. The composite material comprises: 35-87 parts of polypropylene; 3-5 parts of water absorbent resin; 0-40 parts of inorganic mineral powder; 10-20 parts of a toughening agent; 0.3-1.0 part of a processing aid; 0.2-0.8 part of heat stabilizer masterbatch; and 4-6 parts of ozone water. The invention introduces ozone water, and at high temperature, ozone can oxidize low molecular aldehyde, ketone, amine, benzene and other low molecular activity odor matters, and can improve the odor of the polypropylene composite material and decrease the VOC content. According to the invention, an ozone water solution is introduced, at high temperature the water solution is vaporized to produce a lot of water vapor, and a supercritical state can be formed under a melt pressure, thus further extracting low molecules in the polypropylene composite material, improving the odor of the polypropylene composite material, and decreasing the VOC content.

Description

technical field [0001] The invention belongs to the technical field of polymer composite materials, and in particular relates to a low-odor modified polypropylene composite material and a preparation method thereof. [0002] technical background [0003] With the improvement of people's health and environmental awareness, there are more and more complaints about the odor and low-melting volatile harmful substances (VOC) of aldehydes, benzene, and aliphatic hydrocarbons in passenger cars. On the eve of "3.15" this year, The General Administration of Quality Supervision, Inspection and Quarantine released complaints from consumers about the quality of automobile products in the past year, and the air quality inside new cars has become the first of the four focus issues of complaints. [0004] The rapid development of polypropylene modification technology makes it more and more widely used in automotive interior and exterior decoration. However, due to the influence of monomer, ...
