[0022] A kind of preparation method of airtightness enhancer is characterized in that, comprises the following steps:
[0023] Step 1, adding short fiber, asphalt, silicon, alumina powder to the coal powder for proportioning and mixing, wherein, the quantity ratio of adding short fiber is 15% of the input amount of the material; the mass proportion of the material is: asphalt 10%, silicon 5%, alumina powder 5%, coal powder 80%. The order of adding ingredients to coal powder is: asphalt, alumina powder, silicon, and the specific steps of mixing are as follows:
[0024] Step 3.1, add bitumen to coal powder, stir (1) minute;
[0025] Step 3.2, adding alumina powder to the mixed material in step 3.1 and stirring for (1) minute;
[0026] Step 3.3 Add silicon to the mixture completed in Step 3.2 and stir for (1) minute.
[0027] Step 2, putting the mixture that has been metered and mixed in step 1 into a fine powder machine for pulverization and grinding, and then vibrating and s...
