Embodiment 1
[0025] Prepare the resin composition according to the following formula and steps, and apply it as a stone adhesive:
[0026] (1) Preparation of liquid A:
[0027] Mix 100 parts by weight of water-based bisphenol A epoxy resin E51 and 100 parts by weight of non-aqueous epoxy resin E51 evenly, and then add 10 parts by weight of auxiliary agent (allyl glycidyl ether) to prepare liquid A .
[0028] Wherein, the auxiliary agent can also be one or a combination of various types of leveling agents, defoamers, coupling agents and reactive diluents available on the market. For example, the leveling agent can be BYK-306, BYK-333, BYK-323, BYK-358N, BYK-354 etc. of BYK, Germany, Flow300, Glide410, Glide435 of Digaosha (TEGO) company, Glide450, Glide432, WetKL245 etc.; Defoamer can be BYK-141, BYK-052, BYK-066N, BYK-023 of German BYK (BYK) company, FoamexN, Foamex815N, Foamex825 of Digaosha (TEGO) company, Foamex840, Foamex842, etc.; the coupling agent can be American Dow Corning silane...
Embodiment 2
[0036] The present embodiment is substantially the same as Example 1, and the adjustment of its formula is as in Table 1.
[0037] The use time of the resin composition:
[0038] After the resin composition is placed for 30 minutes, the viscosity does not change significantly, that is, the usable time after compounding is greater than 30 minutes.
[0039] Application of resin composition in stone bonding:
[0040] Coat the resin composition on two pieces of stone and bond them accordingly. Cut the stone after 10 days, and the bonded part does not come off; use a hammer to destructively hammer the cut surface of the bonded part of the stone, and the stone is broken as a whole, but The bonded parts of the stone are not detached.
Embodiment 3
[0042] The present embodiment is substantially the same as Example 1, and the adjustment of its formula is as in Table 1.
[0043] And the components of the water-based epoxy resin are as follows: by mass ratio, it includes the following components: bisphenol A epoxy resin E51100 parts; water-soluble radical initiator potassium persulfate 1-30 parts; monomer styrene and acrylonitrile 0-20 parts; water-soluble hardener triethanolamine and ethylenediamine 1-50 parts; phase transfer catalyst crown ether 0.1-5 parts and water 100-200 parts.
[0044] The use time of the resin composition:
[0045] After the resin composition is placed for 30 minutes, the viscosity does not change significantly, that is, the usable time after compounding is greater than 30 minutes.
[0046] Application of resin composition in stone bonding:
[0047] Coat the resin composition on two pieces of stone and bond them accordingly. Cut the stone after 10 days, and the bonded part does not come off; use a...
