Abstract

The invention discloses a sealing filler for cracks in coke oven protection plates, which comprises active ingredients: phenolic resin solution as a continuous phase; silica powder, alumina and gas phase silica as fillers; a dispersed phase, It contains at least one of silane coupling agent, sodium alkyl xanthate and polyoxyethylene ether; where measured in parts by mass: continuous phase: filler: dispersed phase is (0.347-0.497): (0.5-0.65) :(0.003‑0.015). In addition, the invention also discloses a sealing filling material for the cracks of the coke oven protection plate, the mass percentage ratio of each component is as follows: phenolic resin solution as the continuous phase: 34.7-49.7%; silicon dioxide as the filler Powder, alumina and fumed silica: 50-65%; dispersed phase: 0.3-1.5%; dispersed phase is composed of at least one of silane coupling agent, sodium alkylxanthate and polyoxyethylene ether.

Description

technical field [0001] The invention relates to a material and a manufacturing method thereof, in particular to a sealing filler and a manufacturing method thereof. Background technique [0002] During the coking process, the coal is heated in the carbonization chamber in isolation from the air, and undergoes drying and dehydration, thermal cracking, semi-coking and coking. The whole carbonization process is accompanied by the generation of raw gas, especially in the early and middle stages of carbonization. The amount of raw gas is relatively large. [0003] In the process of coking and carbonization, if the coking chamber area of ​​the coke oven body is not tight, it will cause waste gas to overflow, that is, the so-called coke oven body smoke in the daily production process, which will not only cause the loss of chemical products, but also seriously affect the environment of the coke oven ,create pollution. [0004] The coke oven is made of refractory materials such as s...
