Bonding material for steel surfaces and asphalt concrete

Abstract

A bonding material applied to a steel surface and bituminous concrete comprises a component A and a component B at the ratio of 2 to 1, wherein the component A comprises the following ingredients in parts by weight: 2.5-3 parts of an active environment-friendly thinner, 75-90 parts of epoxy resin E51, 5-8 parts of a reactive diluent 501, 2-5 parts of dipropylene glycol and 8-12 parts of an epoxy resin flexibilizer; the component B comprises the following ingredients in parts by weight: 4-6 parts of an active environment-friendly thinner, 8-12 parts of a polyamide curing agent 651, 35-50 parts of a modified amine hardener, 0.8-1.2 parts of an accelerant MP-30, 1.2-1.8 parts of a silane coupling agent Si-69 and 4-6 parts of magnesium oxide. The bonding material has the advantages of being convenient in construction, high in bonding strength, high in impact resistance and high in damage resistance and has the effects of being high in tensile strength, shearing resistance, heat resistance, water resistance and rust resistance.

Description

technical field

[0001] The invention belongs to the field of engineering material bonding, in particular to a bonding material used for steel surfaces and asphalt concrete. Background technique

[0002] With the advancement of domestic transportation engineering technology, more and more steel bridges and steel infrastructures have been built one after another, and the bridge deck with asphalt concrete structure paved with steel surface has attracted more and more attention from engineers and technicians.

[0003] The deformation of long-span steel bridges is large under the action of temperature and load. Steel box girders have good temperature conductivity and are easily affected by changes in external temperature; Various vibrations propagate continuously. Steel box girders are generally welded by light steel plates, and the surface is relatively smooth. It is difficult for ordinary bonding materials to adapt to this working condition. The bonding force of asphalt beyond...
