Problems solved by technology

[0003] Since the polymerization reaction of styrene-acrylic emulsion is carried out in the emulsion, each reaction monomer undergoes a polymerization reaction under the action of an initiator. The initial stage is to absorb heat for the reaction, and then release heat as the reaction progresses. If the control is not proper, it will The occurrence of violent polymerization will cause the loss of reaction materials in light cases, and cause production accidents in severe cases and cause harm

Abstract

The invention discloses an automated production device for styrene-acrylic emulsion mixing and an automated control method of the automated production device. The automated production device comprises a PLC (programmable logic control) system, a polymerization reaction kettle, an overhead acrylate tank, an overhead styrene tank and an overhead initiator tank, wherein a weight sensor is arranged at the bottom of each overhead tank and is connected with the PLC system; a control valve is arranged on each of an acrylate feeding pipe, a styrene feeding pipe and an initiator feeding pipe and is connected with the PLC system; a temperature sensor is arranged on the polymerization reaction kettle and is connected with the PLC system; a control valve is arranged on each of a heated steam pipe and a cooling water pipe and is connected with the PLC system. The automated control method comprises the step that the PLC system automatically adjusts an acrylate feeding control valve, a styrene feeding control valve, an initiator feeding control valve, a heated steam control valve and a cooling water control valve to control the feeding amount and the feeding speed of acrylate solution, styrene solution and an initiator solution and the temperature of the polymerization reaction kettle. The feeding amount and the feeding speed of materials and the flow of heated steam and cooling water are adjusted according to the change of reaction temperature by using the PLC system, so that the temperature of polymerization reaction is stable, and the production safety and the product quality are ensured.

Description

technical field [0001] The invention belongs to the technical field of chemical production, and relates to an automatic production device for styrene-acrylic emulsion polymerization and an automatic control method thereof. Background technique [0002] The so-called styrene-acrylic emulsion refers to a class of chemicals formed by the emulsion polymerization of styrene, acrylate amines and acrylates. It is widely used in the dyeing and printing adhesives of the printing and dyeing industry, and the coating adhesives of the construction industry. , Adhesives for wood processing, etc. [0003] Since the polymerization reaction of styrene-acrylic emulsion is carried out in the emulsion, each reaction monomer undergoes a polymerization reaction under the action of an initiator. The initial stage is to absorb heat for the reaction, and then release heat as the reaction progresses. If the control is not proper, it will The occurrence of violent polymerization will cause the loss ...
