Description
Technical field
The present invention relates to a kind of epoxy resin and preparation method thereof, it is more particularly related to a kind of flexibilizing epoxy
Resin and preparation method thereof, belongs to Epoxy Resin Technology field.
Background technology
Epoxy resin is a kind of thermosetting resin, because having the characteristics such as excellent cementability, mechanical strength and electrical insulating property,
And it is widely used in the aspects such as adhesive, coating and matrices of composite material.But due to pure epoxy resin crisp, the endurance that there is matter
Property, heat resistance and shock resistance difference the shortcomings of, make its application be subject to certain restrictions.Therefore to the toughening modifying of epoxy resin
Research work is always the heat subject of research.The toughness reinforcing approach of epoxy resin has：Mainly include plasticizer toughness reinforcing, low-molecular-weight
Toughener toughness reinforcing, Toughened With High Performance Thermoplastics, core shell structure polymer toughening, IPN toughness reinforcings, thermotropic liquid crystal polymer (TLCP) increase
Tough and heat-resistant powder filler toughness reinforcing, nano-particle toughening etc..These toughening methods can be greatly improved toughness, but
Often it is decreased obviously some mechanical properties of epoxy resin.Wherein, tensile strength and bending strength have decline by a relatively large margin.
Another method of modifying is the toughness that epoxy resin is improved using aliphatic dissaving polymer and hyperbranched epoxy resin, but
It is that the intensity of cured article has also declined.
The content of the invention
Present invention seek to address that the inadequate problem of epoxy resin toughness of the prior art, there is provided a kind of flexibilizing epoxy tree
Fat, the epoxy resin good mechanical properties.
In order to realize foregoing invention purpose, its specific technical scheme is as follows：
It is a kind of epoxy resin toughened, it is characterised in that：Including following raw materials by weight：
30-40 parts of hyperbranched aromatic series liquid epoxies
Single isophorone diisocyanate 10-20 parts
Bisphenol A type epoxy resin 15-20 parts
Epoxy curing agent 15-20 parts
Epoxy resin diluent 20-30 parts
Diethylenetriamine 35-40 parts
Acrylonitrile 60-65 parts
Diluent 30-40 parts.
A kind of epoxy resin toughened preparation method, it is characterised in that：Including following methods step：
A, hyperbranched aromatic series Breakup of Liquid Ring is added in the 250ml round-bottomed flasks with electric mixer, charge door and condenser pipe
Oxygen tree fat, single isophorone diisocyanate, bisphenol A type epoxy resin, epoxy curing agent and epoxy resin diluent；Start
Stirring makes component in bottle be sufficiently mixed uniformly；
B, temperature of reaction system is risen to 50-60 DEG C reaction 2-3h；Temperature of reaction system is risen into 80-90 DEG C of reaction 4-5h；Instead
Should terminate, cool down, discharge, it is standby；
C, diethylenetriamine, acrylonitrile and diluent is added to be sufficiently mixed uniformly according to recipe requirements；The asphalt mixtures modified by epoxy resin that will be mixed
Fat material vacuumizes removing bubble in being positioned over certain pressure vessel；Then the resin compound of deaeration is cast in homemade
In mould；
D, in 70-80 DEG C solidify 2h；90-95 DEG C of solidification 2h；120-140 DEG C of solidification 2h；150-160 DEG C of solidification 4h, obtains final product toughness reinforcing
Epoxy resin.
The Advantageous Effects that the present invention brings：
The present invention employs the different epoxy resin macromolecular graft reaction product of structure according to macromolecule molecular design theory.
There is certain rigid hyperbranched aromatic epoxy resin come toughness reinforcing bisphenol A type epoxy resin by this class for synthesizing.It is this
The good system of compatibility can both utilize the self structure of dissaving polymer and inside has the performance characteristics such as a large amount of holes can
Not only so that the toughness of epoxy resin is improved but also the introducing of substantial amounts of phenyl ring rigid radical can be utilized to improve the strong of product
Degree.Two kinds of epoxy resin compoundings are employed simultaneously, and two kinds of curing agent compound and with the addition of the isocyanide of Third monomer list phorone two
Acid esters (IPDI), thus prepared Graft Epoxy Resin the increasing of good mechanical properties has been obtained through further curing reaction again
Tough modified epoxy.
