Abstract
The invention concerns polyurethane foams with reduced exothermy and to the use thereof for hardening rocks in mining and underground engineering.
Description
The present invention relates to the urethane foam system of low exothermicity and relate to they solidify the geology formulation in underground mining, in tunnel construction and in underground works (Tiefbau) purposes.
Two component polyurethane foams system is used at coal mining consolidated rock and coal and is used for sealing going into flowing water with opposing to a great extent.Is heat release from polyisocyanates and polyvalent alcohol formation urethane in principle.Under adverse environment, because the high reaction temperature that produces in foam makes coal dust on fire.Especially when reaction mixture flows in the big relatively spacious space, the core temperature of urethane foam can be brought up to spontaneous combustion that urethane takes place and the therefore a kind of degree of coal combustion in-situ of making.
For fear of this shortcoming of polyurethane system, EP-A 167 002 has advised using the reaction product of isocyanic ester and alkali metal silicate aqueous solution.EP A 636 154 discloses by polyisocyanates, the reaction of alkali metal silicate aqueous solution and cement.Yet these systems can't be succeedd in practice.
Have now found that by by some polyisocyanate prepolymers and selected polyvalent alcohol and appropriate filler blending, the heat release that urethane forms can be reduced to a kind of degree that no longer includes hazard of catch fire in the consolidation process of rock.
So, the present invention relates to contain polyurethanyl group and the foams that reaction obtained by following component:
