[0002] The crosslinking agent, also known as a bridging agent, curing agent, hardening agent or curing agent, is an important component of polyhydrocarbon photoresists and an important chemical substance in the field of polymer materials. The crosslinking agent is widely used in multiple industries, including rubber, plastics, coatings, adhesives, and the medical aesthetics industry, etc. In the rubber industry, the crosslinking agent (commonly called vulcanizing agent) is one of the key raw materials for preparing rubber products; in the plastics industry, the crosslinking agent is used to improve the strength, heat resistance, wear resistance and other properties of plastics. During production, as a common reaction device, the reaction kettle realizes the functions of heating, evaporation, cooling and mixing at low and high speeds required by the process through the structural design and parameter configuration of the container.

[0003] When the existing device processes multi-layer or raw materials with different densities, the reaction is often uneven due to insufficient stirring, and the situation of raw material stratification is likely to occur, thereby affecting the product quality.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a reaction kettle for crosslinking agent production with an automatic stratification function is proposed, in order to achieve a more practical and valuable purpose.

[0023] The reactor main body 1 adopts a double-layer design. The inner reaction chamber 101 is made of corrosion-resistant material, and the outer layer is a heat-insulating material to reduce heat dissipation. A feed pipe 7 with adjustable height is arranged at the top of the reactor main body 1, and the discharge port of the feed pipe 7 can be extended into different height positions inside the reaction chamber 101 for the feeding of raw materials with different densities, so that the raw materials are stratified and fed during mixing;
