The present invention relates to a polyurethane thermoplastic elastomer, to a composition comprising said polyurethane and a binder, for example bitumen and/or a biobased binder, and also to the use of the composition for the preparation of a waterproofing membrane, a soundproofing membrane, a liquid sealing system, a bituminous mix surfacing, a mastic asphalt surfacing, a primer, a varnish, a mastic, an adhesive or a binder emulsion
摘要:
A rigid foam or composition allowing a rigid foam to be obtained made from polyurethane and/or polyisocyanurate. The rigid foam or composition includes polyols selected from polyester polyols and polyether polyols; the polyols include: 5 to 50% of a polyester polyol A by weight relative to the total weight of the polyols; and a polyol B selected from polyester polyols B and polyether polyols B. The polyester polyol A is of general formula Rx-Ry-Z-Ry′-Rx′ in which Z is a C3 to C8 alcohol sugar chosen from glycerol, sorbitol, erythritol, xylitol, araditol, ribitol, dulcitol, mannitol and volemitol. Ry and Ry′ are diesters of formula —OOC—Cn-COO— in which n is between 2 and 34, and Rx and Rx′ are identical or different C2 to C12 monoalcohols.
摘要:
The invention relates to a method for detecting and flagging a leak in roofing (2), employing a system (1) comprising i) one local detecting and communicating unit for each roofing region (Zi), comprising an elongate sensor and a module (5) for measuring and transmitting at least certain results of the measurements successively carried out, and ii) a management platform (6) configured to receive and process measurements of the modules (5) of various local units managed thereby, and to selectively trigger one or more predetermined actions depending on an evaluation of the received measurements and on an estimation as to whether or not a leak is present, each sensor (4) being installed under the waterproof membrane of the associated roofing region (Zi) and the uplink communication between each local unit and the platform (6) being achieved at least locally through a mode of wireless transmission between the module (5) of the local unit in question and either a local relay terminal, or a base station or even a communication system connected to the Internet.
摘要:
A process for producing a five-membered polycycloaliphatic carbonate including a step of reacting a suspension of a powdered sugar alcohol within a carbon dioxide source and a catalyst compound which is soluble in the carbon dioxide source at the reactional temperature. The invention also concerns a process for producing non-isocyanate polyurethane and/or a polycarbonate and/or polyethers including the step of obtaining a five-membered polycycloaliphatic carbonate according to the process for producing a five-membered polycycloaliphatic carbonate.
摘要:
One subject of the present invention is a roofing device (1) comprising an area support (2) made up of panels of wood particles on which a vapor barrier first layer (3), an insulating second layer (4) and a third layer (5) that is impermeable to liquid water are laid.Said device (1) is one wherein the second layer (4) is a composite layer formed by the superposition of two distinct homogeneous elementary layers (6 and 6′), namely a lower elementary layer (6) of wood fiber and an upper elementary layer (6′) made up of a material that is at least partially bio-sourced, that has hygroscopic, antifungal and thermal-insulation properties and that has a low resistance to the diffusion of water vapor.
