    摘要： This invention relates to a low-viscosity two-component filled polyurethane adhesive comprising(a) a low-viscosity isocyanate component in a quantity sufficient to provide an isocyanate index of about 100 to about 150 comprising an organic polyisocyanate wherein up to 10 equivalent percent of the isocyanate groups of said organic polyisocyanate have been modified by reaction with one or more isocyanate-reactive compounds; and(b) a low-viscosity curative component comprising(i) 5 to 50 equivalent percent, based on the total equivalents of amino and hydroxyl groups of components (b)(i) and (b)(ii), of a polyether polyol and/or a polyether terminated by aromatic amino groups having an equivalent weight greater than 500,(ii) 50 to 95 equivalent percent, based on the total equivalents of amino and hydroxyl groups of components (b)(i) and (b)(ii), of one or more chain extenders and/or crosslinkers, wherein at least one diol chain extender comprises from 50 to 100 percent of the isocyanate-reactive equivalents of component (b)(ii), and(iii) one or more isocyanate-reactive diamines or triamines in a quantity sufficient to produce adequate resistance to flow when components (a) and (b) are mixed;wherein at least one of components (a) or (b) contains at least one filler in a total quantity of from about 10 to about 40 percent by weight of the filled polyurethane adhesive.
