Durable environment-friendly pressure cooker seal ring and preparation process thereof

Abstract

The invention discloses a durable environment-friendly pressure cooker seal ring and a preparation process thereof. The durable environment-friendly pressure cooker seal ring comprises, by weight parts, 30-50 parts of rubber, 20-40 parts of resin, 10-30 parts of modified diatomite, 5-25 parts of highly anti-abrading carbon black, 5-15 parts of N-(cyclohexylthio)phthalimide, 4-12 parts of vinyl silicone oil, 4-12 parts of fatty acid, 1-10 parts of calcium hexadecyl sulfonate, 2-10 parts of butadiene, 1-10 parts of acrylonitrile, 1-10 parts of vulcanizing agent and 1-10 parts of anti-aging agent. The preparation process comprises the steps of first respectively grinding the modified diatomite and the highly anti-abrading carbon black for standby application, cutting the rubber into small pieces and placing the rubber in an internal mixer to perform rubber mixing, adding the resin and the modified diatomite and the like to perform mixing for 3-5 min, adding the vinyl silicone oil and the highly anti-abrading carbon black for mixing, and finally checking trimming deflashing through two-time vulcanization. The pressure cooker seal ring is high in thermal stability, durable, simple to prepare and low in cost.

Description

technical field [0001] The invention belongs to the field of pressure cooker sealing ring manufacturing, and in particular relates to a durable and environment-friendly pressure cooker sealing ring and a preparation process thereof. Background technique [0002] As pressure cookers, electric rice cookers and electric pressure cookers are more and more widely used in household appliances, the demand for sealing rings as accessories is also increasing, and the role of pressure cooker sealing rings in the use of pressure cookers is self-evident. If the sealing ring is missing or the quality of the sealing ring does not meet the requirements of the national and industry standards, the air pressure inside the pressure cooker will leak, which is not conducive to the cooking of food and grain, and will bring a lot of inconvenience. play a very crucial role.

However, the existing pressure cooker sealing rings have many deficiencies in the selection of raw materials and the preparation process, resulting in the low quality of the pressure cooker sealing rings produced, which cannot meet the needs of daily cooking. The main performances are: 1. Poor thermal stability, high temperature 2. It is easy to produce peculiar smell, which affects the quality of food cooking and green health; 3. The durability is poor. The general pressure cooker seal ring is used at least once a day. The longest use The service life is 1-2 years; 4. The production and preparation process is difficult and cumbersome, the energy consumption is high, and the cost of raw materials and processing is high
