摘要 |
<p>An ambient temperature glue, based on a copolymer comprising urea or urethane groups and also isocyanurate groups and containing a trimerization catalyst to form isocyanurate cycles in such a way that the molar ratio of isocyanate groups to the total of amine groups is 1.5-2.2. The copolymer is the reaction product of a polyisocyanate of functionality three or more and comprising isocyanurate cycles and a functional copolymer bearing an amine or alcohol group at each end of the chain and being a polyether diamine or diol, polyester diol or copoly(ester,ester) diol. A chain-extender aromatic diamine may also be used. The polyisocyanate has Brookfield viscosity 8-16 poises and the mixture of functional polymer, trimerization catalyst and chain-extender is 38-46 poises. Independent claims are also included for: (1) a tire tread for retreading having the glue of the claim on its inner face; (2) a tire envelope comprising the claimed tread; and (3) an article comprising two parts adhered together with the glue of the claim, and of which one or both parts is of a crosslinked rubber composition and the other, if not of rubber, is of synthetic fabric, thermo-hardenable polymer, ferrous metal or ferrous metal based alloy and one or both faces has been chemically prepared by treatment with trichlorocyanuric acid before application of the glue.</p> |
