Abstract
The invention discloses a medium-temperature and quickly-cured colorless transparent epoxy resin curing agent, which comprises the following components in part by weight: 55-65 parts of trolamine, 25-35 parts of propene carbonate and 10-15 parts of ethylene diamine. The three raw materials are mixed and reacted to generate the curing agent. The obtained curing agent and the epoxy resin are subjected to glue mixing according to the proportion so as to be heated and quickly cured and generate colorless transparent high-tenacity epoxy resin curing plastic. The medium-temperature and quickly-cured colorless transparent epoxy resin curing agent can be widely applied to perfusion sealing or high-temperature bonding repair of electronic and non-electronic products.
Description
Technical field
The present invention relates to a kind of chemical composition, definite say a kind of novel epoxy curing agent, be specially a kind of middle temperature fast setting water white transparency epoxy curing agent.
Background technology
In the epoxy curing agent of the water white transparency intermediate temperature setting that uses both at home and abroad, selecting maximum is trolamine, it be the water white transparency colloidal liquid after Resins, epoxy mixes, can under 100 ℃ of conditions, solidify fully through 2-3 hour, but quality is firmly crisp, if the words as the electronics irrigation material, because the internal stress of hard crisp generation is too large, often cause electronic devices and components to damage or lead-in wire is broken, and in craft articles or bonding repairing field, do not obtain widespread use because of the crisp easily broken deadly defect of matter yet.
Summary of the invention
The invention provides a kind of middle temperature fast setting water white transparency epoxy curing agent.This solidifying agent has the quick-setting characteristics of middle temperature, has simultaneously the characteristics that the cured glue body is the water white transparency shape; Mix with Resins, epoxy, the Resins, epoxy after the curing has very high toughness, and physical strength is good, and insulation resistivity is high.
The technical solution used in the present invention is as follows for achieving the above object:
A kind of middle temperature fast setting water white transparency epoxy curing agent is characterized in that, the weight part of its each component is:
Trolamine 55-65
Propylene carbonate 25-35
Quadrol 10-15.
Described epoxy curing agent is characterized in that, the weight part of its each component is:
Trolamine 60
Propylene carbonate 28
Quadrol 12.
The preparation method of epoxy curing agent is as follows:
(1) takes by weighing raw material by formula rate;
(2) trolamine that takes by weighing and propylene carbonate are added in the reactor stir;
(3) then, quadrol divided several times add in the reactor, and mixes, after quadrol all adds, restir about half an hour after, remove moisture by vacuumizing, sampling detect qualified after, get final product discharging.
Beneficial effect of the present invention:
This solidifying agent has the quick-setting characteristics of heating, and 100 ℃ of heating were heated and can be solidified fully in 1 hour or 150 ℃ half an hour; Have simultaneously the characteristics that the cured glue body is the water white transparency shape; This solidifying agent mixes with Resins, epoxy, propylene carbonate can improve the toughness of solidifying rear Resins, epoxy, increase physical strength, improve insulation resistivity, can be applicable to dry type transformer, mutual inductor, rly., wave filter, electromagnetic clutch, and in the perfusion seal construction of each adhesive integrated circuit, also can be applied in the non-electronic industry simultaneously, as make the epoxy resin technology product, metal or nonmetallic high temperature resistant bonding are repaired.
Embodiment
A kind of middle temperature fast setting water white transparency epoxy curing agent, the weight part of its each component is:
Trolamine 60
Propylene carbonate 28
Quadrol 12.
The preparation method of epoxy curing agent is as follows:
(1) takes by weighing raw material by formula rate;
(2) trolamine that takes by weighing and propylene carbonate are added in the reactor stir;
(3) then, quadrol divided several times add in the reactor, and mixes, after quadrol all adds, restir about half an hour after, remove moisture by vacuumizing, sampling detect qualified after, get final product discharging.
Example: with Resins, epoxy E
44Or E
51With solidifying agent of the present invention 100 to 30 ratio batching by weight, can be poured in the electronic product after mixing, insert in the electrothermostat at last.100 ℃ of heating were heated and are solidified fully in 1 hour or 150 ℃ half an hour.
Resins, epoxy after the curing has very high toughness, and physical strength is good, and insulation resistance is greater than 10
12Ω is better than general epoxy curing agent, applicable dry type transformer, mutual inductor, rly., wave filter, electromagnetic clutch, and the perfusion seal construction of each adhesive integrated circuit.
In non-electronic industry, also can vigorously promote the use.As make the epoxy resin technology product, metal or nonmetallic high temperature resistant bonding repairing etc. can both reach desirable effect.
