摘要： A flexible gastight material for a landfill site includes a component A and a component B, the component A including: at least one of polypropylene glycol with a molecular weight of 600-4000, polytetrahydrofuran diol with a molecular weight of 1000-3000, polycaprolactone diol with a molecular weight of 1000-3000, and polycarbonate diol with a molecular weight of 1000-3000; and at least one of 2,4′-diphenylmethane diisocyanate, 4,4′-diphenylmethane diisocyanate, toluene diisocyanate, isophorone diisocyanate, and hexamethylene diisocyanate. The flexible gastight material for the landfill site provided in the present application has a micro-closed-cell foam structure. The closed-cell elastic structure of the flexible gastight material may block the volatilization of toxic and harmful odors, and may cut off the diffusion path of the odors by combining with gas treatment systems at the landfill site. The flexible gastight material has excellent water blocking and gas sealing performance.

In addition, one of the two components additionally comprises at least one metal catalyst for the reaction of hydroxyl groups and isocyanate groups which is capable of forming thio complexes, and where the molar ratio of all NCO groups of the polyisocyanates I to all OH groups of the polyols=0.9:1-1.4:1, especially 1.05:1-1.3:1, and where the composition contains, in at least one of the two components, between 3% and 25% by weight, based on the overall composition, of at least one type of microscopic hollow beads, wherein the microscopic hollow beads have a compressive strength, measured to ASTM D3102-72, of at least 10 MPa and a density of at least 0.2 kg/L, and wherein the composition contains, in at least one of the two components, between 2.5% and 7.5% by weight, based on the overall composition, of at least one desiccant, wherein the desiccant is an aluminosilicate.
Such a composition permits arbitrary adjustment of the open time within particular limits, and enables achievement of long open times with subsequent very rapid curing of the composition. The composition of the invention has excellent strength and hardness, and is grindable without difficulty. The composition of the invention is particularly suitable as filling compound, especially for wood.
