Edible oil high-temperature swelling-resistant modified polypropylene material applied to household appliances and preparation method thereof

Abstract

The invention relates to the field of high-molecular materials and discloses an edible oil high-temperature swelling-resistant modified polypropylene material applied to household appliances. The modified polypropylene material comprises the following components in parts by weight: 50-70 parts of polypropylene resin, 15-30 parts of swelling-resistant modified masterbatch, 7-15 parts of inorganic filler, 3-8 parts of a compatilizer, 0.1-0.3 part of a nucleating agent, 0.1-1.0 part of an antioxidant and 0.1-1.0 part of a processing aid. The invention also discloses a preparation method of the edible oil high-temperature swelling-resistant modified polypropylene material applied to the household appliances. The method comprises the following steps: uniformly mixing the polypropylene resin, the swelling-resistant modified masterbatch and the compatilizer, then adding the nucleating agent, the antioxidant and the processing aid, then continuing to stir, then adding the inorganic filler, uniformly stirring, finally adding the mixed materials in an extruder for extruding and granulating to obtain the polypropylene material. The polypropylene material prepared by the invention has high resistance to edible oil high-temperature swelling, high gloss, good scratch resistance, good heat resistance and good rigid-tough balance.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a modified polypropylene material for household appliances resistant to high-temperature swelling of cooking oil and a preparation method thereof. Background technique [0002] Polypropylene (PP) is a crystalline polymer with a regular structure. It is a white pellet, odorless, non-toxic, and light-weight thermoplastic resin. It has easy processing, impact resistance, flex resistance, and good electrical insulation. It has a wide range of applications in the automotive industry, household appliances, electronics, packaging and building materials and furniture. [0003] However, with the rapid development of my country's household electrical appliance industry in recent years, the use effect of PP in some household electrical appliances is not satisfactory, such as the application of the appearance parts of household appliances in the kitchen. Appearance parts will inevitably come...

AI Technical Summary

Problems solved by technology

The polarity of edible oil and PP material is similar, so it is difficult to clean at room temperature, and the surface temperature can reach as high as 80-100°C under the working condition of household appliances, which can easily cause swelling of edible oil on the PP surface
