Problems solved by technology

However, this method is only effective in natural color and black materials. Although it can protect the mechanical properties of the material to a certain extent in bright colored materials, it has a greater impact on the color and color difference of the material, which needs to be improved urgently.

Embodiment 1

[0021] The high weather resistance and anti-aging glass fiber reinforced polypropylene material of this embodiment is composed of the following components by weight: 76 parts of polypropylene PP, 1 part of POE, 2 parts of maleic anhydride grafted PP, 20 parts of chopped glass fiber ( Length: 3~4.5mm; Diameter: 8~15μm), 0.1 part of hindered phenolic antioxidant, 0.1 part of phosphite ester synergistic antioxidant, 0.2 part of lubricant, 0.6 part of ultraviolet absorber, 0.5 part of organic amine Phenolic thermal oxygen stabilizer, 0.0052 part of 10000 mesh ultrafine titanium dioxide, 0.0032 part of azo condensation type Yellow3G yellow, 0.0041 part of monoazo orange, 0.001 part of organic silicon light diffuser.

[0022] The preparation method of the high weather resistance and anti-aging glass fiber reinforced polypropylene material of this embodiment includes the following steps:

[0023] S1. Mix polypropylene, compatibilizer, toughening agent, antioxidant, lubricant, ultraviolet ...

Embodiment 2

[0027] This example is roughly the same as Example 1. The difference lies in the weight of each component. The details are as follows: 57.5 parts of polypropylene PP, 5 parts of POE, 4 parts of maleic anhydride grafted PP, 30 parts of chopped glass fiber (long : 3~4.5mm; diameter: 8~15μm), 0.4 part hindered phenolic antioxidant, 0.2 part phosphite synergistic antioxidant, 0.8 part silicone lubricant, 1 part UV absorber, 1 part organic Amine phenolic thermal oxygen stabilizer, 0.0049 parts of 10000 mesh superfine titanium dioxide, 0.0032 parts of azo condensation type Yellow3G yellow, 0.0040 parts of monoazo orange, 0.002 parts of organic silicon light diffusion agent.

[0028] The preparation method is the same as in Example 1, and will not be repeated. Finally, the obtained material is dried in a blower drying oven at 90° C. for 1 to 2 hours, and then injection molded to prepare test samples and products.

Embodiment 3

[0030] This example is roughly the same as Example 1, and the difference lies in the weight of each component, specifically as follows: 34 parts polypropylene PP, 10 parts POE, 6 parts maleic anhydride grafted PP, 40 parts chopped glass fiber (long : 3~4.5mm; diameter: 8~15μm), 0.6 part hindered phenolic antioxidant, 0.6 part phosphite synergistic antioxidant, 0.8 part silicone lubricant, 2 part UV absorber, 2 part organic Amine phenolic thermal oxygen stabilizer, 0.0049 parts of 10000 mesh superfine titanium dioxide, 0.0032 parts of azo condensation type Yellow3G yellow, 0.0040 parts of monoazo orange, 0.002 parts of organic silicon light diffusion agent.

[0031] The preparation method is the same as in Example 1, and will not be repeated. Finally, the obtained material is dried in a blower drying oven at 90° C. for 1 to 2 hours, and then injection molded to prepare test samples and products.

Abstract

The invention discloses a high-weather-resistant anti-aging glass fiber reinforced polypropylene material. Through the synergistic action of such components of the material as polypropylene (PP), a chopped glass fiber, a compatible flexibilizer, an anti-oxidant, a lubricant, a coupling agent, one or more ultraviolet light absorbers, a thermo-oxidative stabilizer and one or more toners, as well as reasonable selection of specific components in parts by weight, changes in the color difference of color glass fiber reinforced PP can be greatly reduced under the light-heat aging condition, and the mechanical property retention rate can be high; when the material is applied to automobile parts, household appliances and other products, the problems that the product properties are degraded and the product colors are changed due to long-term exposure of such products in the open air or a high-temperature environment can be effectively solved. The invention further discloses a preparation method of the material. The preparation method is simple to operate, low in cost and high in production benefit; the material obtained according to the preparation method is high in mechanical property, retention rate and color stability, and very suitable for industrialized production; through the preparation method, not only can the service life of the material be prolonged, but also environmental pollution can be reduced.

Description

Technical field [0001] The invention relates to a high-weather-resistant and anti-aging glass fiber reinforced polypropylene material and a preparation method thereof, belonging to the technical field of polymer material modification and processing. Background technique [0002] Polypropylene (PP for short) is a semi-crystalline thermoplastic with high impact resistance, strong mechanical properties, resistance to a variety of organic solvents, acid and alkali corrosion, and good shrinkage. Its mineral reinforcement materials are widely used Used in many fields such as auto parts, electronic appliances, strollers, children's toys, etc. In recent years, mineral-reinforced polypropylene materials have also been widely used in auto parts, home appliances and other fields, and have very good application prospects. The color difference of its appearance and color changes within 0.5 under normal conditions, but under thermal oxygen light aging When used in some abnormal environments t...
