Abstract
The invention discloses a latent curing agent with multiple storage stability. The latent curing agent has the characteristics of being nontoxic and inodorous and belongs to an environment-friendly curing agent. The latent curing agent is characterized by containing organic acids, inorganic compounds, 4,4 '-diamino diphenyl methane and dibutyl phthalate. Aiming at solving the problems that epoxy or epoxy-modified unsaturated polyester has poor usage stability and needs timely replacement or addition when being used for trickle-dipping and roll-dipping solventless varnish, the invention provides an amine complex curing agent, wherein at certain temperature, an epoxy group can be opened by amine, zinc and epoxy can form an alkoxy compound, while the amine can be restrained below 40 DEG C, therefore, the usage stability at room temperature is sustained by multiple times and the latent curing agent has extensive application value in the occasions of trickle-dipping and roll-dipping electrical coils, and the like.
Description
Technical field
The present invention relates to a kind of solidifying agent, particularly relate to a kind of latent curing agent as Resins, epoxy and epoxide modified unsaturated polyester.
Background technology
Solidifying agent has another name called stiffening agent, ripening agent or set agent, is curing reaction is promoted or controlled to a class material or mixture.Resin solidification is through chemical reactions such as condensation, closed loop, addition or catalysis, makes thermosetting resin that irreversible change procedure take place, and curing is finished by adding curing (crosslinked) agent.Present epoxy or epoxide modified unsaturated polyester are used for dripping and soak, roll and soak solvent-free paint, and under the situation that single component is used, 40 ℃ of following life cycles were generally 24 hours, needed in time to change or add, and troublesome poeration is met Holidays, even can cause and scrap or stop work.Simultaneously common amine curing agent exists and causes and swash anxious heat release, and the shortcoming of electrical property and thermal characteristics difference can not satisfy the needs of actual use.
Summary of the invention
Be used for dripping and soak, roll that to soak the solvent-free paint stability in use relatively poor in order to solve in the prior art epoxy or epoxide modified unsaturated polyester, the problem that needs replacing in time or add, the invention provides a kind of amine complex compound solidifying agent, at a certain temperature, amine can be opened epoxy group(ing), zinc can form alkoxy compound with epoxy, but can restraining effect arranged to amine again below 40 ℃, thereby several times ground prolongs the stability in use under the room temperature, soaks dripping of electric coil, rolls and occasion such as soak and have use value more widely.
In order to address the above problem, the technical solution used in the present invention is:
A kind of latent curing agent with several times package stability is characterized in that: comprise naphthenic acid, zinc oxide, 4.4 ' diaminodiphenylmethane, dibutyl phthalate, its molar constituent is:
Naphthenic acid 1.0-2.5
Zinc oxide 1-1.5
4.4 ' diaminodiphenylmethane 0.2-0.4
Dibutyl phthalate 0.2-0.4
Aforesaid a kind of latent curing agent with several times package stability is characterized in that: comprise naphthenic acid, zinc oxide, 4.4 ' diaminodiphenylmethane, dibutyl phthalate, its molar constituent is:

A kind of latent curing agent with several times package stability is characterized in that: comprise sad, zinc sulfate, 4.4 ' diaminodiphenylmethane, dibutyl phthalate, also added sodium hydroxide, its molar constituent is:
Sad 1.0-2.5
Zinc sulfate 1-1.5
Sodium hydroxide 1.0-2.5
4.4 ' diaminodiphenylmethane 0.2-0.4
Dibutyl phthalate 0.2-0.4
Aforesaid a kind of latent curing agent with several times package stability is characterized in that: comprise sad, zinc sulfate, 4.4 ' diaminodiphenylmethane, dibutyl phthalate, also added sodium hydroxide, its molar constituent is:
Sad 2.5
Zinc sulfate 1.5
Sodium hydroxide 2.5
4.4 ' diaminodiphenylmethane 0.2
Dibutyl phthalate 0.4
The invention has the beneficial effects as follows:
1, solidifying agent of the present invention is a kind of amine complex compound solidifying agent, after solidifying agent decomposes at a certain temperature, curing to Resins, epoxy, solidifying agent plays a major role, and amine hardener plays a driving role, therefore the sharp anxious heat release that does not have common amine curing agent to cause, the shortcoming of electrical property and thermal characteristics difference.Below 40 ℃, main solidifying agent and amine synthesize the complex compound state, can play stabilization again to amine curing agent, and therefore, life cycle obtains the prolongation of several times ground under the room temperature.
2, solidifying agent of the present invention is a kind of amine complex compound solidifying agent, at a certain temperature, still has amine solidified characteristics, and effect is as follows:
The temperature gel time
120 ℃＜2 minutes
110 ℃＜5 minutes
100 ℃＜15 minutes
90 ℃＜30 minutes
3, solidifying agent of the present invention is an amine complex compound solidifying agent, and this solidifying agent has stabilization to amine curing agent again in certain temperature range:
Temperature is not coagulated the change time
60 ℃ 2 days
50 ℃ 3 days
40 ℃ 〉=4 days
30 ℃ 〉=10 days
25 ℃ 〉=30 days
Solidifying agent of the present invention is used for dripping when soaking, rolling the epoxy resin dipping solvent-free paint, and the single component life cycle can reach 1 month below 25 ℃, and two components have the package stability of half a year, are very easy to use.
4, remaining hydroxyl and carboxyl has coupling in solidifying agent of the present invention and the unsaturated polyester resin, with unsaturated polyester good consistency is arranged, this solidifying agent is again the good solidifying agent of Resins, epoxy simultaneously, therefore, both can be separately as curing agent for epoxy resin, can be used as the common solidifying agent of epoxy and unsaturated polyester again, thereby enlarged the range of application of these two kinds of resins.
5, the nontoxic odorless of solidifying agent of the present invention, with Resins, epoxy at 120 ℃, 0.5-1 hour is promptly curable, volatile matter during curing≤1% is a kind of epoxy type solidifying agent.
