Abstract
The invention is an alicyclic amine modified epoxy resin hardener, using aminomethyl cyclopentamine as material for modification. Its characteristic: it is synthesized of epoxy resin active diluting agents like aminomethyl cyclopentamine, alkyl alcohol glycidyl ether/organic acid glycidic ester, etc, and/or small molecular weight epoxy resin, and other raw materials. The hardener has moderate active hydrogen equivalent, low viscosity, and hardens at normal temperature, and the hardening course has the characters of low heat release, no toxic and excitive volatile, being uneasy to absorb moisture and blush, good compatibility with the epoxy resin, condensate with light colors and even colorless, etc, and it is an environmental protection hardener. It shows very good performance as used in self-leveling coating and ordinary floor coating, electronic sealing material, handicraft decoration, etc.
Description
Technical field
The invention belongs to the material field of epoxy resin cure, relate to as the application based on aspects such as epoxy adhesive, coating, Embedding Material, decorations, particular content is aliphatic cyclic amine modification based epoxy resin curing agent and preparation method thereof.
Background technology
Epoxy curing agent kind as the self-vulcanizing of bonding, embedding and coating is a lot, usually belong to organic fat amine or its modification series products, have that bonding process is simple, cohesive strength is excellent, shrinking percentage is little, characteristics such as mechanical property, dielectric properties, chemical stability are good, but, all exist easy variable color, moisture absorption whiting has the pungency volatile matter, and have even needs or system big because of viscosity are added with contaminate environment, threaten the organic solvent of HUMAN HEALTH as thinner; Be used for terrace paint finish paint and artwork decoration and not only need high cohesive strength, need good smooth finish, color stability, lighter color or colourless, need also to consider that cured article has reasonable toughness, especially in embedding, build the field, snappiness requires more outstanding, and usually, people mostly use alicyclic ring amine or its modified product, at present, the alicyclic ring amine curing agent major part of use is organic amine and the modified product thereof that the hexane ring is arranged.In a word, the binding agent of each purposes, potting compound, coating and artwork are decorated material all needs to have multiple outstanding physics, machinery, many-sided performance such as electric, these performances press for solidifying agent and provide, and therefore, people give more expectation to epoxy curing agent.
Summary of the invention
The object of the present invention is to provide and a kind ofly make that the cured article product color is shallow, colour stable, snappiness/hardness is reasonable, surface gloss is high, environment and human body are not had the solidifying agent organic amine modification that the pentane ring is arranged and the epoxy resin at room temp reaction of multiple excellent properties such as hazardous substance, it has all advantages of fatty amine and hexane lopps organic amine curing agent.
Technical scheme of the present invention is: aliphatic cyclic amine modification based epoxy resin curing agent feature is made up of according to mol ratio following raw material, and the prescription moiety is as follows: feed composition 350～50mol such as epoxide resin reactive diluent such as amine methyl cyclopentamine 100mol, alkyl alcohol glycidyl ether or organic acid glycidyl ester.
Product of the present invention cooperates the back to have in application such as bonding, embedding, top coat coating and artwork decoration with Resins, epoxy outstanding advantage:
1. bonding firmly.Cooperate with Resins, epoxy to solidify under the room temperature of back to get final product, do not need other slaking.
2. the reactive hydrogen equivalent value significantly improves, and significantly reduces the condensate performance difference that the weighing operate miss causes.
3. whole system does not have volatile injurant matter not have inert diluent yet, and human body and environment are not had health threat.
4. the moisture absorption of curing system, whiting are significantly improved.Gloss of film degree height, lighter color, color and luster is stable, if use high quality liquid Resins, epoxy, working method is correct, can obtain water white transparency, glittering and translucent cured article.
5. the system curing speed that mixes with Resins, epoxy is fast, can reach maximum temperature in 40～60 minutes under the room temperature, and the heat release concentration phenomenon is alleviated greatly.
6. cured article has good toughness/hardness.
7. coloring effect is fine, and the system wettability is good.
8. multiple performances such as water tolerance, chemical-resistant, electrical insulating property, wear resistance, wet fastness, wear resistance are all no less than curative systems commonly used.
According to the final performance requriements of cured article, suitably adjust the solidifying agent proportioning, also can add an amount of weighting material according to actual needs, can obtain the outstanding cured article product of some performance.
Embodiment
Be described in detail specific embodiments of the invention below.
In devices such as mounted enamel glass reactor, metered charge jar, vacuum pump, drying nitrogen protection, add amine methyl cyclopentamine 100mol under the room temperature, butylglycidyl ether 100 ± 10mol; With the air in the nitrogen replacement reactor, start stirring and be warmed up to 50 ℃ simultaneously, controlled temperature is 50-90 ℃, can lead to the cooling water control temperature of reaction in reinforced process.Keep 90 ℃ of reactions 90 minutes, cool to 35 ℃ of discharging packings.Drying nitrogen is full of the remaining space of reactor in entire reaction course.
According to the method described above and the prescription, the performance that obtains product is as follows:
Appearance colorless or light yellow fluxion
Viscosity 10～25s (being coated with 4 glasss)
Amine equivalent 100～130g/mol
Reactive hydrogen equivalent 80～100g/mol
