Example Embodiment

[0014] Examples:

[0015] First, carry out the preheating of stearic acid: transfer the stearic acid in liquid state into the calcium stearate reactor through a pump and pipeline, and control the addition amount of stearic acid through a flow meter installed on the pipeline. The stearic acid in the calcium reactor is heated to 150-180°C. The calcium stearate reactor involved in the present invention includes a reactor body 1, a stirring shaft 2, a stirring paddle 3, a motor 4, and a reducer 5. The kettle body 1 is a horizontal kettle body, in which a horizontal stirring shaft 2 is arranged. The stirring shaft 2 is equipped with seven sets of stirring paddles 3, and each set of stirring paddles 3 are two vertical to each other. The scraper blades of the kettle body 1 is provided with a motor 4, which is connected to the stirring shaft 2 through a reducer 5;

Abstract

The invention relates to a calcium stearate fusion production process and a calcium stearate reaction kettle thereof. The invention is characterized in that the process comprises the following steps: pumping stearic acid in the liquid state into a flowmeter for metering, then transferring into the calcium stearate reaction kettle, and heating while stirring; and adding calcium hydroxide and a catalyst, and reacting at the temperature of 150-180 DEG C and the pressure intensity of 0.6-1.0 MPa, wherein the complete reaction time is 45-65 minutes. Since the reaction is pressurized, the reaction rate is accelerated; and meanwhile, in order to further accelerate the reaction speed, the horizontal reaction kettle is used, thereby ensuring more uniform stirring and more sufficient reaction, further shortening the reaction time and stabilizing the quality of the product.

Description

technical field [0001] The present invention relates to a kind of calcium stearate melting method production technology, also relate to a kind of calcium stearate reaction kettle used for calcium stearate melting method production technology. Background technique [0002] Stearate is widely used in petrochemical, daily chemical, rubber and plastic, dyestuff, medicine, metallurgy, military industry, paint, paint and other industries, mainly as polyethylene, polypropylene, polyvinyl chloride, chlorinated polyethylene and other polymers Heat stabilizers for material processing as well as lubricants and dispersants for coatings, varnishes, and paper industries. With the strengthening of people's awareness of environmental protection, stearates of toxic substances such as lead salts are gradually eliminated, while the demand for non-toxic heat stabilizer calcium stearate is increasing. [0003] The technology of producing calcium stearate at home and abroad mainly contains three...
