Problems solved by technology

In addition to providing a reaction space, the reactor will also heat up or cool down the phenolic resin according to the needs of different stages of the production process. If the temperature is not raised or lowered in time during the reaction process of the phenolic resin, it will easily lead to denaturation, curing and even violent occurrence of phenolic resin. On the other hand, if the phenolic resin is in the production process, the temperature at each point of the reaction phase is inconsistent, which will cause the molecular weight distribution of the phenolic resin to be too wide, thereby reducing the performance of the resin
[0003] Since the resin reaction process needs to be stirred, in order not to affect the normal operation of the stirring parts, the current phenolic resin special reactor uses the reactor jacket or built-in circular coil to adjust the reaction temperature. The built-in coil is close to the inner wall of the reactor, and the above scheme is adopted. The main technical problems are: 1. Since the phenolic resin special reaction kettle is provided with a reaction kettle jacket or a built-in circular coil to form a space separated from the upper and lower sides, the liquid phase of the phenolic resin cannot be uniformly mixed up and down, so that the phenolic resin liquid is stirred Inhomogeneous; 2. Under the agitation of the stirring paddle, a turbulent liquid phase of phenolic resin is formed. In this way, during the reaction, the center temperature and edge temperature of the reaction phase are inconsistent, which can easily reduce the performance of the resin or cause safety accidents.

Abstract

The invention belongs to the technical field of phenolic resin reaction, and discloses a novel reaction kettle for phenolic resin reaction. A revolving body is fixedly arranged in the centers of special-shaped coil pipes; the special-shaped coil pipes are fixedly arranged on the stirring shaft in parallel up and down through the revolving body, and the upper special-shaped coil pipe and the lowerspecial-shaped coil pipe are fixedly communicated through an inclined stirring paddle which is arranged in an inclined manner; a temperature control medium inlet is fixedly formed in the upper part ofthe left side of the reaction kettle body, and a temperature control medium outlet is fixedly formed in the lower part of the right side of the reaction kettle body; and the anchor type stirring paddle is fixedly arranged at the bottom of the stirring shaft. The stirring uniformity of the phenolic resin reaction liquid phase is greatly improved, the consistency and uniformity of the center temperature and the edge temperature of the phenolic resin reaction phase are improved, and the product performance of phenolic resin is improved.

Description

technical field [0001] The invention belongs to the technical field of phenolic resin reaction, and in particular relates to a novel reaction kettle used for phenolic resin reaction. Background technique [0002] In the production process of phenolic resin, the reaction of phenolic resin needs to be completed in a special reactor. In addition to providing a reaction space, the reactor will also heat up or cool down the phenolic resin according to the needs of different stages of the production process. If the temperature is not raised or lowered in time during the reaction process of the phenolic resin, it will easily lead to denaturation, curing and even violent occurrence of phenolic resin. On the other hand, if the temperature of each point of the reaction phase is inconsistent during the production process of the phenolic resin, it will cause the molecular weight distribution of the phenolic resin to be too wide, thereby reducing the performance of the resin.
