Amino-modified silicone oil emulsification reactor

Abstract

The invention belongs to the technical field of novel emulsification, and particularly relates to an amino-modified silicone oil emulsification reactor. The reactor comprises a container main body, ajacket, a main stirrer and a porous shearing stirrer, wherein the main stirrer and porous shearing stirrer are mounted in a concentric-shaft form and can be operated at differential rotational speeds,and the main stirrer comprises three layers of paddles with different paddle-inclining angles; fluid force at the paddle-inclining angles are generated by a material under the action of the paddles,and flow impact in different directions are formed, so that full mixed flow is achieved; four layers of paddles of the porous shearing stirrer and the paddles of the main stirrer are staggered, convection impact is formed by fluid of the main stirrer and the paddles of the porous shearing sitter, and shearing is performed at a porous part; and in addition to the action of a mobile wall-scraping plate, the material adhered to a wall can be scraped off, so that the material is updated quickly, and emulsion is excellent. The prepared silicone oil emulsion has narrow particle size distribution, and the method is suitable for oil-in-water emulsion of different viscosities and particle sizes; the method can also be applied to the reaction process of other viscous material systems.

Description

technical field [0001] The invention belongs to the technical field of novel silicone oil emulsification, in particular to an amino silicone oil emulsification reactor. Background technique [0002] Silicone oil (polysiloxane), that is, organosilicon compound, refers to a compound containing Si-0 bonds and at least one organic group directly connected to a silicon atom. It has excellent chemical stability, heat and cold resistance, and weather resistance. , hydrophobicity, lubricity, high refraction and storage stability, widely used in various industries, including automobile, construction, chemical, electrical engineering and electronics industry, pharmaceutical industry, pulp and paper, transportation industry, aerospace industry , textile, leather, mechanical engineering, metal processing and other fields. High-viscosity silicone oil is a high-viscosity fluid. Due to its good film-forming properties, it can be used to repair hair damage and improve combability. At the s...

AI Technical Summary

Problems solved by technology

Due to the high viscosity of amino silicone oil, the existing emulsification equipment usually uses a conventional stirring reactor. Due to the structure of the stirrer, it cannot meet the requirements of good mixing of the amino silicone oil system, so it cannot meet the requirements of water and emulsifier (water phase) ) and silicone oil (oil phase) are well emulsified, the prepared emulsion has a wide particle size distribution and the product is unstable
