15 parts, 2~5 parts of elastic nano solid granulates.
It is preferred that described elastic nano solid granulates are one or more in carbon black, silica or alundum (Al2O3)
The composite nanometer particle of individual modified rubber.
Present invention also offers a kind of preparation method of solid granulates reinforced epoxy, it is mainly characterized by, described
Preparation method comprises the following steps：
Step (1)：Raw materials bisphenol A types epoxy resin, curing agent are stirred under vacuum；
Step (2)：Bisphenol A type epoxy resin after vacuum stirring, curing agent are delivered in mixing kettle, by described bullet
Property the described mixing kettle of nano solid particle input in auxiliary material storage at, then described mixing kettle is vacuumized；
Step (3)：Make mixing kettle heating stirring, mix 0.5~1h；
Step (4) adds described elastic nano solid granulates mixing at auxiliary material storage, and holding mixing kettle temperature is
60 DEG C~70 DEG C, keep 0.5~1h；
Mixed liquor is placed in 80 DEG C~100 DEG C of mould by step (5), solidification, cooling and demolding, solidify afterwards, you can obtain
Described solid granulates reinforced epoxy.
It is preferred that described raw materials bisphenol A types epoxy resin, curing agent are liquid.
It is preferred that institute's elastic nano solid granulates are put into described mixing kettle by described step (2) after fully drying
In auxiliary material storage at.
The beneficial effect of the solid granulates reinforced epoxy of the present invention and preparation method thereof is：With traditional enhancing ring
Oxygen tree fat and preparation method are compared, and preparation method provided by the invention stirs raw material and mixed liquor under vacuum, reduce oxygen
Influence of the gases such as gas, hydrogen to mixed process；Controlled on temperature and time strictly, it is fully mixed in epoxy resin and curing agent
When temperature is 60-70 DEG C after conjunction, elastic nano solid granulates are added, elastic nano solid granulates is preferably mixed with mixed liquor
Close, and the present invention makes it preferably contact and act on mixed liquor using elastic nano solid granulates are added by different level, and it is similar
Compare, elongation at break substantially increases, and its toughness and splitting resistance are remarkably reinforced, and neither reduces epoxy resin solid
Tg, and can ensure the use technique of epoxy resin, ensure the toughness and splitting resistance of solidfied material.
Embodiment
In order to more clearly describe the technology contents of the present invention, carried out with reference to specific embodiment further
