Title:
炭鉱用多機能封止剤及びその製造方法
Document Type and Number:
Japanese Patent JP7454170
Kind Code:
B2
Abstract:
Provided is a multi-functional plugging agent for a coal mine and a preparation method thereof. The preparation method comprises: by taking Ecklonia Kurome Okam as a raw material, mixing an Ecklonia Kurome Okam suspension with phosphorus pentoxide for reaction, then performing biodegradation to obtain an Ecklonia Kurome Okam biological extract, adding urea for neutralization, mixing a neutralization product with an inorganic catalyst and melamine for reaction to obtain a bio-based plugging synergist solution, finally cooling the bio-based plugging synergist solution, and mixing the cooled bio-based plugging synergist solution with a certain amount of pentaerythritol and ammonium polyphosphate to obtain the multi-functional plugging agent for the coal mine based on the Ecklonia Kurome Okam biological extract. According to the invention, not only a coal crack can be effectively plugged for a long time, but also an efficient flame-retardant effect can be achieved in a complete period of coal spontaneous combustion.
