Abstract
The invention provides a kind of super soft epoxy curing agent, which comprises the chemical reaction of combination with four chemicals of diethylenediamine, propylene carbonate, oleic acid, and castor oil. The curing agent is blended into super soft epoxy adhesive with epoxy resin and epoxy diluent. Finally, the super soft epoxy adhesive is used in the application of cloth cover, or widely used in bonding repair, house wall decoration and so on.
Description
Technical field
The present invention relates to a kind of super soft epoxy hardener composition and preparation method thereof, belongs to firming agent technical field.
Background technology
In order that thin cloth is firm with epoxy glue bonding, typically one layer of glue can be coated with the thin cloth of coated glue, at present,
Existing but one-component binding agent can reach the purpose of coating bonding, but the binding agent needs 250 DEG C could be solidified.It is such
Condition of cure is too harsh, now needs to seek a kind of 80 ~ 100 DEG C of i.e. curable flexible glues, to reach the purpose of coating bonding.
Low-temperature setting adhesive of the prior art mainly has following several：
Hydroxy'terminated butadiene nitrile rubber is epoxy binder modified.
Epoxy resin（E-51） 100；
Hydroxyl terminated butyl nitrile (HTBN) rubber（HTBN） 16；
Diethylenetriamine 10-15；
Two pungent vinegar 5 of decanedioic acid；
Room temperature 24 hours is i.e. curable, or 80 DEG C two hours it is curable.
After this epoxy adhesive curing, toughness is greatly improved, but without flexibility.
Thiorubber. is epoxy binder modified also many formula, selects preferable formula as follows：
Component A epoxy resin（E-44） 100；
Thiorubber.： 20-30；
Tricresyl phosphate： 10-15；
Aluminium oxide powder（300 mesh） 50-60；
Other auxiliary agents are appropriate；
B component five amine of methylvinyl-sulphur urine condensation substance 15-25；
Component A：B component proportioning=100：25.
Can solidify within two hours in 80 ~ 100 DEG C.Solidfied material is still high tenacity, does not reach the degree of flexibility.
Polyurethane elastomer is epoxy binder modified more than ten formula, selects both simple, and performance and preferably formula are such as
Under：
Epoxy resin（E-51） 100；
Epoxy-terminated polyurethane 25；
Polyamide（650） 80；
100 DEG C two hours it is curable, it is flexible but do not reach requirement.
It is in several formula of silicon-modified epoxy adhesive, as follows compared with the formula being suitable for：
E -20 epoxy resin 30；
Organic siliconresin 30；
Dimethylbenzene 30；
Polyvinyl butyral resin（PVB） 7.5；
Dicy-curing agent 2.5；
This formulation cured temperature is higher, and 160 DEG C of need solidify for two hours, and the epoxy resin after solidification has preferable toughness and flexibility,
It is basically available.But solidification temperature is high, and will add dimethylbenzene, abnormal smells from the patient is big, not environmentally, therefore should not adopt.
Various formula more than comprehensive, do not reach requirement.Through many tests, develop both simple and of good performance
After novel Curing Agents for Epoxy Resins, with epoxy resin impregnation, add appropriate diluent just can use, two are heated in 80 ~ 100 DEG C of baking ovens
Hour is curable.
The content of the invention
For defect of the prior art, it is an object of the invention to provide a kind of super soft epoxy hardener composition and its system
Preparation Method.
The present invention is achieved by the following technical solutions：
The present invention provides a kind of super soft epoxy hardener composition, and which includes the following component counted by weight：
20 ~ 40 parts of diethylenetriamine；
10 ~ 30 parts of Allyl carbonate；
20 ~ 30 parts of Oleic acid；
20 ~ 30 parts of Oleum Ricini.
Preferably, the parts by weight of each component are respectively：
30 parts of diethylenetriamine；
20 parts of Allyl carbonate；
25 parts of Oleic acid；
25 parts of Oleum Ricini.
The present invention principle be：Four kinds of materials all contain double-strand, belong to olefines chemical substance, and four kinds of materials enter
Row copolymerization, defines longer strand, and this is the principle to form Flexible Curing Agent.
It is analyzed by the property of every kind of raw material.Diethylenetriamine is organic primary amine, belongs to organic alkali material, chemistry
Property is active.Allyl carbonate is unsaturated Ester, and Oleic acid and Oleum Ricini are the unsaturated fatty acids things of longer chain
Matter, these three materials can promptly carry out acid-base neutralization reaction and copolymerization with diethylenetriamine, once so mixing
Just start spontaneous heating and produce violent chemical reaction, and product is then the thick organic basic with flexible longer chain
Compound.More specifically, the present invention has been provided with the molecular structure speciality of fabulous flexibility, combines to obtain without many kinds of substance
Obtain flexible.
A kind of preparation method of super soft epoxy hardener composition as the aforementioned, which comprises the steps：
Allyl carbonate, Oleic acid and Oleum Ricini are mixed, profit shape troubled liquor is obtained；
Diethylenetriamine is added in the profit shape troubled liquor, after mixing, is reacted at 100 DEG C, obtain described super
Soft epoxy hardener composition.
Compared with prior art, the present invention has following beneficial effect：
It is of the present invention to work well Jing after construction.Super soft epoxy glue is combined dense softness with thin cloth, can arbitrarily be folded and will not be ruptured, will
The epoxy glue for preparing is dropped in, and has fully met the technical requirements of user；
After the present invention and epoxy resin impregnation, room temperature solidifies for 48 hours, it may also be used for common cloth cover coating, house wall surface decoration
And the bonding in life is repaired, the such as repairing of sneakers, damaged reparation of umbrella cover roof leaking etc..
