Abstract
The present invention relates to a glass steel-magnesite concrete compounded support material for a mining well. Magnesite concrete materials can be manufactured into base materials according to a mould, are dipped in dipping solution composed of polymers, are externally coated with a glass steel coating layer and then are solidified; thereby, the glass steel-magnesite concrete compounded support material for a mining well is manufactured. The tension resistance, the pressing resistance and the intensity resistance are higher than those of timber, and compared with single magnesite concrete materials, the glass steel-magnesite concrete compounded support material has the advantages of high anti-folding performance, high corrosion resistance and low cost.
Description
The present invention relates to a kind of glass reinforced plastic and steel-magnesite concrete compounded support material for mining well, is a kind of support material that is used for coal mine operation engineering roadway, also can be applied to and make support material when the local operation of wet corrosion.
The material that is used for shaft and drift supporting generally uses timber, steel.But through metal every year is by corrosion loss 1%, especially acidly expands well and only uses 2-3, a large amount of consume steel.What produce is materials such as concrete, masonry, plastics, glass reinforced plastic thereupon, but owing to respectively there are many shortcomings, for example heavy, shortcomings such as cost is high, undercapacity are not used gradually, therefore and the magnesite concrete that is to use that rises is made support material.The most normal what run into is exactly anticorrosion waterproof problem but the magnesite concrete is as the support material of down-hole life-time service, but because intensity is low, must strengthen overstriking, thereby heavy.According to the most normal problem that runs in the present actual use under the condition of humidity, easily loosen, buckling deformation is also dangerous, spillage of material is also bigger.
The objective of the invention is: glass reinforced plastic and the steel-magnesite concrete compounded support material for mining well of developing a kind of high strength, corrosion-resistant, novel mine support material that price is low.
The solution of the present invention is as follows: the core of mine support material is tabular or column magnesite concrete mother metal 2, it is characterized in that the magnesite concrete mother metal of making must put into as behind the polymer-modified steeping fluid dipping, outside core, coat one deck glass reinforced plastic coating layer 1 again and form.Above-mentioned glass reinforced plastic coating layer is with neutral-alkaline cloth and fiber glass resin liquid winding up mother metal, reaches desired thickness after solidify and to form at it.As its component of polymer-modified steeping fluid is (weight ratio):
Coal tar pitch or coal tar 0.5～1
Furans or phenolic aldehyde 1～1.5
The present invention is as the mine support material, and its mother metal has the material behavior that timber has behind polymer-modified dipping, high tensile, resistance to compression, anti-tearing open, and outsourcing glass reinforced plastic coating material has not only strengthened the intensity of support material, and corrosion-resistant.Replenished the deficiency of simple magnesite concrete support material, again like simple glass reinforced plastic as support material cost an arm and a leg, the insufficient shortcoming of rigidity.Support material can be done arbitrary structures design, makes rounded section, rectangle, shape such as I-shaped.
Below by drawings and Examples the present invention is illustrated:
Fig. 1-2 is a structure iron of the present invention.
Fig. 1 is the structure iron of tabular support material;
Fig. 2 is the structure iron of column support material.
Embodiment 1:
The first step is with magnesite concrete and bamboo reinforcement, by being molded as plank frame mother metal 2, then above-mentioned mother metal being put into steeping fluid floods, mother metal external application neutral-alkaline cloth (thick 0.4mm) winding up unsaturated polyester resin liquid plate shape reaches more than the 1mm coating layer thickness of two sides with hand paste method then, more than the interlude thickness 4mm, following two reduces to more than the 2mm, reaches thickness with after be solidified to form glass reinforced plastic coating layer 1.
Steeping fluid component (weight proportion):
Coal tar or coal tar pitch 1
Phenolic aldehyde or furans 1.5
Unsaturated polyester resin liquid component (weight proportion):
191
#Unsaturated polyester resin liquid 100
Cyclohexanone peroxide 3～4
Acid resistant cobalt liquid 1～4
Also available epoxy replaces unsaturated polyester resin liquid.
Embodiment 2:
The first step by being molded as column magnesite concrete mother metal 2, is placed on mother metal the dipping as polymer-modified steeping fluid with magnesite concrete and bamboo reed muscle then.Coat above-mentioned magnesite concrete core with neutral-alkaline cloth and fiber glass resin liquid winding up then, make to reach desired thickness after be solidified to form glass reinforced plastic coating layer 1.
The outer thick frp layer of 1～2mm that coats of column magnesite concrete mother metal.
The component of steeping fluid (weight proportion):
Coal tar pitch or coal tar 0.7
Furans or phenolic aldehyde 1.2
Claims (1)
1. glass reinforced plastic and steel-magnesite concrete compounded support material for mining well, its core is tabular or column magnesite concrete mother metal (2), it is characterized in that above-mentioned magnesite concrete mother metal must being put into and form as being coated with glass reinforced plastic coating layer (1) again behind the polymer-modified steeping fluid dipping, above-mentioned glass reinforced plastic coating layer is to reach required coating thickness with neutral-alkaline cloth and fiber glass resin liquid winding up coating mother metal at it to form through curing, and above-mentioned is (weight proportion) as its component of polymer-modified steeping fluid:
Coal tar pitch or coal tar 0.5～1
Furans or phenolic aldehyde 1～1.5
