Abstract
The invention discloses a kind of slim supporting fire proofing materials, including sulphate aluminium cement, water, acrylic acid, calcium carbonate and basalt fibre.The beneficial effects of the invention are as follows the materials on the basis of playing supporting to country rock, while can effectively solve the problem that the destruction that underground is under fire to roadway support, secondary disaster caused by avoiding the occurrence of because of supporting.
Description
Technical field
The invention belongs to fireproof material technology fields, are related to a kind of slim supporting fire proofing material.
Background technique
A kind of support pattern of the concrete-spraying technology as underworkings, have it is low in cost, supporting effect it is significant and
The advantages that applied widely, but for the special sector of some Special Laneways, supporting effect is unsatisfactory, because of the invention one
The novel slim support material of kind, slim support material is with spray-up is thin, quality is close, compression strength is high, curing time is fast, energy
The advantages that enough and working face well coheres, gradually gets the nod and applies in mine.For underground easily ignition tunnel section, pass
The gunite concrete of system cannot achieve fireproof effect, but the present invention utilizes basalt using sulphate aluminium cement as binder
Fiber makees Prospect for Flame Retardant Fiber Materials, and silica and aluminium hydroxide are done fire retardant, compounded with certain proportion, can effectively solve the problem that underground
The destruction being under fire to roadway support, secondary disaster caused by avoiding the occurrence of because of supporting.
Summary of the invention
The purpose of the present invention is to provide a kind of slim supporting fire proofing materials, and the beneficial effects of the invention are as follows the materials right
It on the basis of country rock plays supporting, while can effectively solve the problem that the destruction that underground is under fire to roadway support, avoid the occurrence of because of supporting
Caused secondary disaster.
The technical scheme adopted by the invention is that including sulphate aluminium cement, water, acrylic acid, calcium carbonate and basalt are fine
Dimension.
Further, 40 parts by weight of sulphate aluminium cement, 60 parts by weight of water, 2 parts by weight of acrylic acid, 2 parts by weight of calcium carbonate and
0.6 parts by weight of basalt fibre.
Further, the mass ratio of titanium dioxide and magnesium hydroxide is 4:6.
Further, quick hardening sulphoaluminate cement selects 42.5 grades.
It further, further include 0.9 parts by weight of accelerator, 0.2 parts by weight of polycarboxylate high performance water-reducing agent, second class powered coal ash
2 parts by weight.
It further, further include 0.004 parts by weight of sodium salt dispersing agent, 0.004 parts by weight of rolydimethylsiloxane defoamer, ten
Two carbon alcohol ester film forming agents, 0.02 parts by weight.
Specific embodiment
The present invention is described in detail With reference to embodiment.
Embodiment: 40 parts by weight of sulphate aluminium cement, 60 parts by weight of water, 2 parts by weight of acrylic acid, 2 parts by weight of calcium carbonate and
0.6 parts by weight of basalt fibre.
For the fire protecting performance of reinforcing material, the present invention selects silica and aluminium hydroxide as fire retardant, neutralizes two
The mass ratio of titanium oxide and magnesium hydroxide is 4:6.
The stability of slim spray-up entirety when to guarantee that tunnel is under fire, the present invention select basalt fibre as fire-retardant fibre
Dimension is 0.6 mass parts.
42.5 grades of quick hardening sulphoaluminate cements are selected, acrylic acid selects water-based acrylic resin.
0.9 parts by weight of accelerator, 0.2 parts by weight of polycarboxylate high performance water-reducing agent, 2 parts by weight of second class powered coal ash.
0.004 parts by weight of sodium salt dispersing agent, 0.004 parts by weight of rolydimethylsiloxane defoamer, Lauryl Alcohol ester film forming
0.02 parts by weight of agent.
When material configures, first by sulphate aluminium cement, titanium dioxide, aluminium hydroxide, basalt fibre, calcium carbonate, two
The solid additives such as grade flyash stir evenly.In addition by sodium salt dispersing agent, rolydimethylsiloxane defoamer, Lauryl Alcohol ester
The liquid additives such as film forming agent, acrylic acid stir evenly.
Liquid material and solid additives are stirred evenly when use, being put into flush coater can be used.
The above is only not to make limit in any form to the present invention to better embodiment of the invention
System, any simple modification that embodiment of above is made according to the technical essence of the invention, equivalent variations and modification,
Belong in the range of technical solution of the present invention.
