It should be noted that, the solution selects the compatibilization particles with the diameter of more than 0mm to less than 4mm, and the compatibilization particles select the diameter range, so that the filling performance of the slurry can be well ensured, and a better dissolving effect is achieved. Meanwhile, it is to be noted that: the compatibilized particles selected by the applicant are particulate materials utilizing the super high molecular weight type high water absorption property.
The polyester fiber is in a ribbon shape, the length of the polyester fiber is L, and the range of L is as follows: l is more than or equal to 10mm and less than or equal to 12 mm.
It should be noted that, the length of this scheme selection is in the scope of 10mm to 12mm can guarantee that thick liquids play higher mixed degree when carrying out mixing stirring processing, reduces and fills the space.
Compared with the prior art, the invention has the following advantages and beneficial effects:
1. the addition of the capacity-increasing particles can ensure that the slurry is more fully fused, and can ensure that the door frame plugging difficulty is reduced, so that the fireproof performance is improved;
2. the addition of the polyester fiber further ensures the filling performance of the grouting filler and reduces the possibility of existence of voids.
