Abstract
An epoxy resin-bitumen material composition is prepared by mixing an epoxy resin and a bitumen material in the presence of a co-solubilizer represented by the general formula ##STR1## wherein R is hydrogen or a hydrocarbyl group having 1-9 carbon atoms, R' is an alkylene group having 2-3 carbon atoms, n is an integer 1-10 inclusive, and p and q are respectively an integer of 0-40 in average. The resulting composition is useful as a road pavement material, bonding material for railroad track ballast, anti-corrosion agent, etc. The cured product resulting from this composition is advantageous in that it has good heat resistance and free from bleeding.
Claims17
An epoxy resin-bitumen material composition comprising an epoxy resin, a bitumen material selected from a class consisting of asphalts and lubricating oils and a mixture of novolakbased polyether-polyols represented by the general formula:
- ##STR7## wherein R is hydrogen or a hydrocarbyl group having 1-9 carbon atoms, R' represents --CH.sub.2 --CH.sub.2 -- or --CH.sub.2 --CH.sub.2 --CH.sub.2 --, n is an integer of 1-10 inclusive, and each of p and q is an integer within the range of 0-40 and the average value of each in the mixture is 3-30.
In the method for preparing epoxy resin-bitumen material composition, an improvement comprising admixing a bitumen material selected from a class consisting of asphalt materials and lubricating oil materials and a co-solubilizer which is a polyether-polyol obtained by reacting one mole of a novolak resin represented by the general formula ##STR10## wherein n is an integer of 1-10 inclusive, R is hydrogen or a hydrocarbyl group having 1-9 carbon atoms, with at least three moles of ethylene oxide or propylene oxide.
