Coke oven burner grouting material and manufacturing method thereof

Abstract

The invention discloses a coke oven burner grouting material. The coke oven burner grouting material comprises the following effective components: liquid phenolic resin serving as a base material, silicon dioxide powder, mullite powder and clay refractory mortar serving as fillers, and a silane coupling agent and polydimethylsiloxane serving as additives, wherein the mass part ratio of the base material to the fillers to the additives is (0.25-0.35): (0.64-0.74): (0.005-0.015). In addition, the invention further discloses a coke oven burner grouting material which comprises the following components in percentage by mass: 25-35% of liquid phenolic resin serving as a base material, 64-74% of silica powder, mullite powder and clay refractory mortar serving as fillers, and 0.5-1.5% of a silanecoupling agent and polydimethylsiloxane which are used as additives. In addition, the invention further discloses a manufacturing method of the coke oven burner grouting material. The coke oven burner grouting material has the characteristics of favorable flowability and favorable dispersity.

Description

technical field [0001] The invention relates to a material and a manufacturing method thereof, in particular to a grouting material 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 a...

AI Technical Summary

Problems solved by technology

The grouting material mainly made of clay and fire mud has poor fluidity and can only be used when the new coke oven is put into operation at low temperature. It is difficult to use the grouting method for the put into operation coke oven, and it is easy to harden and crack after sintering at high temperature

Although there are some high-temperature-resistant sealing materials in the prior art, they are not suitable for grouting the gap between the coke oven protection plate and the furnace body

And there are defects such as high cost, easy volatilization and carbonization of solvents at high temperatures
