The curing agent disclosed by the invention is obtained by mixing the raw materials according to requirements and reacting; then the obtained curing agent is mixed with epoxy resin in a proportion, and the epoxy resin is cured at the temperature of 150 DEG C for 30 minutes; the cured epoxy resin has high toughness, excellent mechanical strength, and insulation resistance greater than 10<12> omega; and the curing agent is suitable for perfusion sealing construction of dry-type transformers, mutual inductors, relays, temperature sensors and various integrated circuits.
Description
Technical field
The present invention relates to a kind of solidifying agent, definite a kind of novel epoxy curing agent of saying so is specially a kind of heating fast solidifying liquid anhydride curing agent.
?
Background technology
In Resins, epoxy acid curing agent field, adopting both at home and abroad mostly acid anhydride type curing agent is the heating cure as Resins, epoxy of Tetra hydro Phthalic anhydride and MALEIC ANHYDRIDE, and can resistant to elevated temperatures acid curing agent.Because these two kinds of anhydride curing agents commonly used are crystalline solid, use very inconvenient, for easy to use, domestic and international many manufacturer production multiple liquid anhydride replace MALEIC ANHYDRIDE and phthalic anhydride.As 647 acid anhydrides, 70 and 80 liquid anhydride.The appearance of these acid anhydrides is given in the operation and has been brought convenience, and still, the set time of these LCM is all long, and 100 ℃ or 150 ℃ of heating ability curing in 3-8 hour down, the consumption that had so both increased the energy has also reduced production efficiency simultaneously usually.
?
Summary of the invention
The invention provides a kind of heating fast solidifying liquid anhydride curing agent.When this solidifying agent and Resins, epoxy are joined glue, short following set time in the condition of heating, and the material after solidifying has the characteristics of high temperature resistant, high tenacity, low-stress.
The technical solution used in the present invention is as follows for achieving the above object:

The preparation method of described heating fast solidifying liquid anhydride curing agent is characterized in that concrete operations are as follows:
(1) takes by weighing starting material by formula rate;
(2) add in the reactor propylene carbonate and the trolamine that takes by weighing and stirring earlier;
(3) will pour in the reactor after the phenol heating and melting, mix, stir with propylene carbonate and trolamine in the still;
(4) mixture of step (3) stirs after 30 minutes and to add after vinylformic acid continues to stir, MALEIC ANHYDRIDE is added wherein in batches, constantly stir, simultaneously system is heated, after MALEIC ANHYDRIDE is all melted when treating that material is warming up to 80 ℃, stop heating;
(5) restir half an hour after MALEIC ANHYDRIDE is all melted, vacuumize then and remove moisture content, treat that material gets final product discharging when being cooled to 60 ℃ of left and right sides naturally.
Beneficial effect of the present invention:
This solidifying agent is the liquid anhydride solidifying agent, have characteristics easy to use, this solidifying agent is with after Resins, epoxy mixes, under the condition of heating, set time is short, promptly curable 100 ℃ of 1 hour or 150 ℃ of half an hour, Resins, epoxy after the curing has high tenacity, low internal stress, physical strength is good, the characteristics that insulation resistivity is high, can be applicable to rly., wave filter, in the perfusion seal construction of temperature sensor and unicircuit, also can be applied in the non-electron trade simultaneously, as making the epoxy resin technology product, metal or nonmetallic high temperature resistant bonding are repaired.Because set time is short, has reduced the consumption of the energy, has saved production cost, has improved production efficiency.
Embodiment
A kind of high temperature resistant cured epoxy resin solidifying agent, the weight part of its each component is:
MALEIC ANHYDRIDE 40
Phenol 10
Trolamine 5
Vinylformic acid 25
Propylene carbonate 20.
The preparation method of described heating fast solidifying liquid anhydride curing agent, concrete operations are as follows:
(1) takes by weighing starting material by formula rate;

(4) mixture of step (3) stirs after 30 minutes and to add after vinylformic acid continues to stir, MALEIC ANHYDRIDE is added wherein in batches, constantly stir, simultaneously system is heated, after MALEIC ANHYDRIDE is all melted when treating that material is warming up to 80 ℃, stop heating;
(5) restir half an hour after MALEIC ANHYDRIDE is all melted, vacuumize then and remove moisture content, treat that material gets final product discharging when being cooled to 60 ℃ of left and right sides naturally.
Application examples: during use, with Resins, epoxy E
44Or E
51With the epoxy curing agent of the present invention ratio batching of 100:100 by weight, can be poured in the electronic product after mixing, and insert in the electrothermostat, be completely solidified 150 ℃ of heating half an hour, and working temperature can be anti-200 ℃, and insulation resistance is greater than 10
12Ω.
Owing to added propylene carbonate, the more existing solidifying agent of solidifying agent of the present invention is significantly improved, and the Resins, epoxy after the curing has very high toughness, the physical strength excellence, and working temperature can be anti-200 ℃, and insulation resistance is greater than 10
12Ω and, be fit to the perfusion seal construction of dry type transformer, mutual inductor, rly., temperature sensor and each adhesive integrated circuit.
In non-electron trade, also can vigorously promote the use.Especially to metal or the repairing of nonmetallic high temperature resistant high tenacity bonding etc., can both reach the ideal effect.
