Temperature-controllable rubber dissolving tank

Abstract

The invention discloses a temperature-controllable rubber dissolving tank, belonging to the field of resin production equipment. According to the temperature-controllable rubber dissolving tank, a jacket is additionally arranged on an existing rubber dissolving tank and is filled with heat conduction oil; the heat conduction oil is circulated through an additionally arranged circulating pump, and low-temperature hot oil (80 DEG C) is quantitatively added into an inlet of the circulating pump through a regulating valve to control the temperature of the jacket, so the temperature of a rubber solution can be accurately controlled; and thus, an optimal dissolving temperature can be set according to different rubber varieties, a rubber dissolving speed can be increased, self-polymerization of styrene can be avoided, full-load stable operation of the device is ensured, the influence of the environment temperature (especially in cold winter) on the rubber dissolving speed is effectively eliminated. In addition, by improving the shape of the inner shell of the dissolving tank, the inner shell and the jacket form a closed system, so on one hand, heat conduction efficiency can be effectively improved and a dissolving speed is further increased, and on the other hand, rubber can be effectively prevented from being hung on a wall to affect stirring effect.

Description

technical field [0001] The invention relates to the field of resin production equipment, in particular to a temperature-controllable rubber dissolution tank. Background technique [0002] Resin usually refers to an organic polymer that softens or melts after being heated, has a tendency to flow under external force when softened, and is solid, semi-solid, or sometimes liquid at room temperature. In a broad definition, any polymer compound that can be used as a raw material for plastic products is called a resin. [0003] Dissolving quantitative BR\SBR rubber in styrene monomer to prepare styrene rubber solution is an indispensable link in the production process of HIPS and bulk ABS resin. After the rubber machine cuts into 10-15mm particles, it falls into a dissolving tank with a certain liquid level of styrene, and dissolves into a uniform rubber solution under the action of stirring. [0004] The concentration of rubber produced by HIPS and ABS resin is 7-15%, and the di...

AI Technical Summary

Problems solved by technology

[0004] The concentration of rubber produced by HIPS and ABS resin is 7-15%, and the dissolution time is long, usually 3-4 hours, which is one of the bottlenecks restricting the production capacity of the device, especially in winter, when the temperature is low, rubber in styrene The solubility in the medium decreases, resulting in prolonged dissolution time or forced to reduce the rubber concentration, and the production capacity of the device has to be reduced accordingly
