Description

Technical Field

[0001] The utility model relates to the technical field of flame retardant polypropylene material preparation, in particular to a reaction kettle for preparing the flame retardant polypropylene material. Background Art

[0002] The existing flame-retardant polypropylene material preparation reactor uses high-pressure gas injection to create an invisible gas wall at the through-hole port, so that the stirred material liquid will not enter the through-hole. When the auxiliary material is added, the high-pressure air pump is directly turned off to make the circular inclined plate lose its pushing force. Then, under the strong elastic force of the spring, the circular inclined plate will be quickly driven back to its original position and the through-hole will be blocked, so that the through-hole can discharge the material while preventing the entry of liquid.

[0003] In order to improve the dispersibility and compatibility of flame retardants in polypropylene, a strategy of adding in batches may be adopted. However, in the preparation process of existing flame-retardant polypropylene materials, high-pressure gas is input at the bottom of the reactor for mixing, which causes splashing during the process of opening the reactor to add materials, causing the operator to be at risk of high-temperature burns. After searching, it was found that the technical solution provided by the utility model with application number CN202122035929.6 also has the above-mentioned problems. Utility Model Content
