Glass fiber-reinforced epoxy resin or polyester resin composition and method for manufacturing same
Abstract
Abstract A GLASS FIBER-REINFORCED, EPOXY RESIN OR UNSATURATED POLYESTER RESIN COMPOSITION COMPRISING GLASS FIBER, AN EPOXY RESIN OR AN UNSATURATED POLYESTER RESIN, AND, AT THE INTERFACE OF SAID GLASS FIBER AND RESIN, A REACTION PRODUCT OF A PARTIALLY EPOXIDIED POLYBUTADIENE HAVING AT LEAST ABOUT 50 MOLE PERCENT OF 1,2-STRUCTURE WITH A MERCAPTOORGANOSILANE OF THE FORMULA, HS-(CH2)N-SI(-R1)(-R2)-R3 WHEREIN R1, R2 AND R3, WHICH MAY BE THE SAMD OR DIFFERENT, REPRESENT HYDROLYZABLE RADICALS CAPABLE OF REACTING WITH GLASS FIBER, FOR EXAMPLE, ALKOXY GROUPS HAVING 1 TO 3 CARBON ATOMS, ACETOXY GROUPS OR HALOGEN ATOMS, AND N IS AN INTEGER OF FROM 1 TO 4. BY THE PRESENCE OF SAID REACTION PRODUCT AT THE INTERFACE, THE ADHESION BETWEEN THE GLASS FIBER AND THE RESIN IS IMPROVED AND THERE IS OBTAINED A REINFORCED PLASTIC HAVING A HIGH STRENGTH AND EXCELLENT TRANSPARENCY.
