Easy-to-clean polypropylene composite material for see-through electric rice cooker and its preparation method and application

Abstract

The invention discloses an easy-to-clean polypropylene composite material for a see-through rice cooker, a preparation method and an application. The composite material is composed of, by mass, 30-80% of high-crystallized homo-polypropylene, 1-20% of transparent filler masterbatches, 0.5-10% of polytetrafluoroethylene micro powder, 10-40% of nano-silica masterbatches, 0.1-0.5% of hindered phenolic antioxidants, 0.1-1% of phosphorated antioxidants, 0.1-1% of thioester antioxidants and 0.1-2% of lubricating agents. The components are mixed evenly and then added in a parallel twin screw extruder to be blended, melted and extruded to obtain the composite material. The composite material has the advantages of resisting high temperature and long-term thermo-oxidative aging, being easy to form and excellent in comprehensive physical and mechanical performance and the like, and can be applied to the field of small household appliances such as rice cookers, pressure cookers, induction cookers and soybean milk machines.

Description

technical field [0001] The invention relates to a polymer composite material, in particular to an easy-to-clean polypropylene composite material for see-through electric rice cookers and its preparation method and application, belonging to the technical field of modified plastics. Background technique [0002] Polypropylene is non-toxic, odorless, and has low density. It can be used for tableware. It is one of the five general-purpose plastics and is widely used in household appliances, automobiles, and daily necessities. [0003] At present, most of the common rice cooker shells on the market are made of opaque modified polypropylene composite materials. When the rice cooker is working, the lid covers the body, making it difficult for users to check the cooking status of the food in the pot. Open the lid to check However, there are the following disadvantages: one is that the high-temperature steam is easy to burn the user, the other is that part of the heat loss affects th...

Problems solved by technology

[0003] At present, most of the common rice cooker shells on the market are made of opaque modified polypropylene composite materials. When the rice cooker is working, the lid covers the body, making it difficult for users to check the cooking status of the food in the pot. Open the lid to check However, there are the following disadvantages: first, high-temperature steam is easy to burn the user; second, part of the heat loss affects the heating efficiency; third, part of the nutrients are released with the steam and affect the taste of food

[0005] In addition, when the polypropylene material is used as the shell of the rice cooker, it is easy to be stained with grease, smoke, fingerprints and other stains during daily use, and it is difficult to clean it, which seriously affects the original gorgeous and bright appearance of the outer parts of the appliance.
