0.2 part of Graphene.Wherein, the epoxy resin is epoxy resin 6101, and the curing agent is Versamid.
Embodiment 6：A kind of bark of eucommia resinous binder compositions, 4.5 parts of bark of eucommia resin, 1.5 parts of epoxy resin and curing agent 4
Part, 0.2 part of Graphene.Wherein, the epoxy resin is epoxy resin 6101, and the curing agent is Versamid.
Comparative example 1：A kind of bark of eucommia resinous binder compositions, 4 parts of 0 part of bark of eucommia resin, 6 parts of epoxy resin and curing agent.
Wherein, the curing agent is Versamid.
Comparative example 2：A kind of bark of eucommia resinous binder compositions, 4 parts of 6 parts of bark of eucommia resin, 0 part of epoxy resin and curing agent.
Wherein, the curing agent is Versamid.
In above example and comparative example, bark of eucommia resin replaces epoxy resin with four kinds of different proportions：(1：3)；(1：
1)；(3:1)；And whole substituted epoxy resins, contrasted with pure epoxy resin formula (comparative example 1 and comparative example 2), bond aluminium
Piece and stainless steel substrates gained shear strength result, are listed in Table 1 below.As can be seen from Table 1, bark of eucommia resin demand is less than and equal to ring
Two formulas (1 of oxygen tree fat:3 and 1：1) aluminium flake or stainless steel substrates, are either bonded, shear strength all increases, is bonded
Aluminium flake brings up to 53 kilograms per centimeters square from 40 kilograms per centimeters square；Stainless steel substrates intensity is bonded to be carried from 43 kilogram centimeters square
Height works as bark of eucommia resin demand more than after epoxy resin to 70 kilogram centimeters square, and the intensity for bonding aluminium flake is just reduced to only
23 kilograms per centimeters square, especially all instead of epoxy resin when, either bond aluminium flake or stainless steel substrates, intensity is
Zero, illustrate only not reacted with bark of eucommia resin and curing agent.
But, plus after Graphene, when bonding stainless steel substrates, all formula intensity are improved, highest one is matched somebody with somebody can
Up to 80 kilograms per centimeters square (in addition to the formula for all being replaced with bark of eucommia resin), when bonding aluminium flake, intensity can be to 61 kilogram centimeters
Square, illustrate that Graphene is having good humidification in this system.
Table 1, four kinds of different proportion bark of eucommia resins replace epoxy bond intensity contrast：
