And the effect of adhesive A is to make to precoat primer layer and flexible parent metal stable adhesion, and keep precoating primer layer and levelling resin layer steady
Fixed bonding；And as can be seen from the above table, (the comparative example when the parts by weight of the light-cured resin a in adhesive A are less than 15 parts
1), it can make adhesive A in curing process, heated and complete surface drying causes adhesive A cannot be with the liquid in levelling resin B
State component generates liquid-liquid contact, leads to precoat primer layer and levelling the resin layer nothing (under UV conditions of exposure) in Light Curing
Method accomplishes co-curing, bonding, thus the phenomenon that being easy to appear interlaminar separation；When the weight of the light-cured resin a in adhesive A
When part is greater than 30 parts (comparative example 2), the shrinking percentage of adhesive A is greater than 5%, will cause the bonding force of adhesive A and flexible backings
Not enough, the phenomenon that being easy to appear interlaminar separation.
In addition, the effect of levelling resin B is to make levelling resin layer and precoating primer layer stable adhesion, and make levelling resin layer
With 3D abrasive material stable adhesion, wherein the light-cured resin b in levelling resin B is in Light Curing (under UV conditions of exposure)
Instantaneous solidification (3s in solidification) can be adhesively fixed with precoating primer layer, 3D abrasive material respectively, so convenient for 3D grinding tool first product from
The removing of pattern chamber, so as to accomplish that pipeline system produces, high production efficiency.
In addition, the effect of adhesive C is: abrasive micro-powder as the binder in 3D abrasive material raw material, is fixedly arranged at one by 1.
It rises；It is reacted 2. can be crosslinked with levelling resin B, guarantees the adhesive strength between levelling resin layer and 3D abrasive material, to make
Last molding 3D grinding tool is convenient for removing from shaping mold cavity；And as can be seen from the above table, the light-cured resin in adhesive C
When the parts by weight of a are greater than 30 parts (comparative example 3), the shrinking percentage of adhesive C is greater than 5%, on the one hand can make the interior of 3D abrasive material
Stress is excessive, influences grinding tool wearability and service life, on the other hand biggish shrinking percentage causes to shrink, and then makes the shape of 3D abrasive material
It changes, preset shape cannot be obtained；(the comparative example when the parts by weight of the light-cured resin a in adhesive C are less than 15 parts
4), it can make adhesive C in curing process, heated and complete surface drying causes adhesive C cannot be with the liquid in levelling resin B
State component generates liquid-liquid contact, causes 3D abrasive material and levelling resin layer can not (under UV conditions of exposure) in Light Curing
Accomplish co-curing, bonding, the phenomenon that influencing adhesive property, be easy to appear interlaminar separation.
Above-described embodiment is the preferable implementation of the present invention, and in addition to this, the present invention can be realized with other way,
Do not depart under the premise of present inventive concept it is any obviously replace it is within the scope of the present invention.
