Preparation device of modified epoxy resin

Abstract

The invention relates to the technical field of epoxy resin preparation, and discloses a preparation device of modified epoxy resin. The preparation device comprises a base, a solid flow meter is installed on a first feeding hopper, a liquid flow meter is installed on a second feeding hopper, and a liquid collecting tank is arranged at the bottom end of the interior of a purification box. An activated carbon screen plate is mounted in the purification box above the liquid collecting tank, an air extracting pump is mounted at the top of the purification box, the input end of the air extracting pump is connected with a stirring box through an air guide pipeline, and the output end of the air extracting pump is connected with the liquid collecting tank through an air guide pipeline. According to the preparation device of the modified epoxy resin, by arranging the solid flow meter, the liquid flow meter, the liquid collecting tank, the air extracting pump and the activated carbon screen plate, the preparation device has the functions of controlling metering and feeding and purifying gas, materials are conveniently and reasonably added, the quality of the modified epoxy resin is improved, and meanwhile harmful gas is absorbed; and harmful gas is prevented from injuring a human body, and the functionality is improved.

Description

technical field [0001] The invention relates to the technical field of epoxy resin preparation, in particular to a preparation device for modified epoxy resin. Background technique [0002] Epoxy resin is a kind of high molecular polymer, which refers to the general term of a class of polymers containing more than two epoxy groups in the molecule. It is the polycondensation product of epichlorohydrin and bisphenol A or polyol. Due to the chemical activity of the epoxy group, a variety of compounds containing active hydrogen can be used to open the ring, cure and cross-link to form a network structure, so it is a thermosetting resin. Bisphenol A epoxy resin not only has the largest output and the most complete variety, but also new modified varieties are still increasing, and the quality is constantly improving. [0003] At present, in the process of preparing modified epoxy resin, it is difficult to grasp the appropriate measurement through manual feeding, which leads to t...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a modified epoxy resin preparation device, which has the advantages of controlling the metering and feeding function and the gas purification function, and solves the problem of manually Feeding is prone to excessive feeding, which will affect the preparation time and the quality of the final product. Secondly, different solvents or other harmful substances need to be put in during the preparation process, resulting in the harmful substances produced during the preparation will be directly discharged into the air. The body of the staff is injured, and it affects the surrounding environment
