Embodiment 1
[0043] This embodiment provides a kind of epoxy resin paint, comprises base material and amine curing agent, and described base material raw material is composed of:
[0044]
[0045]
[0046] The preparation method of the self-emulsifying epoxy resin modified by the organosilicon oligomer comprises the steps:
[0047]1) Mix γ-glycidyl etheroxypropyltrimethoxysilane (KH560), dimethyldiethoxysilane, and water for hydrolysis, the hydrolysis temperature is 60°C, and the hydrolysis time is 4h. The γ-glycidol Etheroxypropyltrimethoxysilane: dimethyldiethoxysilane: the mass ratio of water is 100:20:10 to obtain the organosilicon oligomer (the number average molecular weight of the organosilicon oligomer is 500- 1000);
[0048] 2) Silicone oligomer and self-emulsifying epoxy resin (self-emulsifying epoxy resin is self-emulsifying bisphenol A epoxy resin with epoxy equivalent 188-200, purchased from Allnex Company, model 147W) are mixed and heated for modification , the modifi...
Embodiment 2
[0056] This embodiment provides a kind of epoxy resin paint, comprises base material and amine curing agent, and described base material raw material is composed of:
[0057]
[0058] The preparation method of the self-emulsifying epoxy resin modified by the organosilicon oligomer comprises the steps:
[0059] 1) Mix γ-glycidyl etheroxypropyltrimethoxysilane (KH560), diphenyldiethoxysilane, and water for hydrolysis. The hydrolysis temperature is 65°C, and the hydrolysis time is 4 hours. The γ-glycidol Etheroxypropyltrimethoxysilane: diphenyldiethoxysilane: the mass ratio of water is 100:20:10 to obtain the organosilicon oligomer (the number average molecular weight of the organosilicon oligomer is 600- 1000);
[0060] 2) Silicone oligomer and self-emulsifying epoxy resin (self-emulsifying epoxy resin is a self-emulsifying novolac epoxy resin with a functionality of 2.3 and an epoxy equivalent of 172-182, purchased from Huntsman Company, model PY340-2) Mixing and heating f...
Embodiment 3
[0068] This embodiment provides a kind of epoxy resin paint, comprises base material and amine curing agent, and described base material raw material is composed of:
[0069]
[0070] The preparation method of the self-emulsifying epoxy resin modified by the organosilicon oligomer comprises the steps:
[0071] 1) Mix γ-glycidyl etheroxypropyltrimethoxysilane (KH560), dimethyldiethoxysilane, and water for hydrolysis, the hydrolysis temperature is 55°C, and the hydrolysis time is 5h. The γ-glycidol Etheroxypropyltrimethoxysilane: dimethyldiethoxysilane: the mass ratio of water is 100:15:15, to obtain the organosilicon oligomer (the number average molecular weight of the organosilicon oligomer is 600- 800);
[0072] 2) Silicone oligomer and self-emulsifying epoxy resin (self-emulsifying epoxy resin is self-emulsifying bisphenol A epoxy resin with epoxy equivalent 188-200, purchased from Allnex Company, model 147W) are mixed and heated for modification , the modification temp...
