Abstract
The present invention belongs to the technical field of resin curing and provides a universal multifunction resin curing agent II which can be applied to the curing under the heating condition of epoxy resin and the curing of a mixture of phenolic resin and furan resin. A curing active species of the curing agent has two or more kinds of curing functional groups with different properties (not only-NH2 and/or-CONH2 functional groups, but also-SO3 H functional groups) and stage A phenolic resin or furan resin. The present invention with a wide application range and high universality has the characteristics of high activity, fire resistance, low toxicity, stabilization, no volatilization, corrosion or pollution, etc.
Description
The invention belongs to the organic chemistry class, relate to the resin solidification technical field.
Solidifying agent is a kind of can the generation or initiating chamical reaction with resin (natural or synthetic), makes resin by the liquid solid state that is converted into, and makes it to have the compound of certain mechanical strength and cohesive force and corrosion resistant performance.If various resins lack the effect of solidifying agent, just lost its use value.This shows that solidifying agent is how important to the curing of resin.Solidifying agent in use deal only accounts for a seldom part, generally only accounts for the 5-20% of weight resin.Solidifying agent is divided into mineral-type solidifying agent and organic class solidifying agent two big classes.
At present, synthetic resins commonly used both at home and abroad has except that unsaturated polyester resin: three major types such as Resins, epoxy, resol, furans (chaff ketone) resin.
Curing agent for epoxy resin has derivatives class solidifying agent, half latent curing agent, acid anhydride type curing agent and the resene solidifying agent etc. of aromatic amine solidifying agent, aliphatics amine solidifying agent, tertiary amines solidifying agent, secondary amine class solidifying agent, amine.
Phenolic resin curative has benzene sulfonyl chloride, p-methyl benzene sulfonic chloride, sulfovinic acid, mahogany acid, dodecyl sodium sulfonate and naphthene sulfonic acid etc.
Furan resin hardener has sulfovinic acid, benzene sulfonyl chloride, p-methyl benzene sulfonic chloride, phosphoric acid, p-methyl benzenesulfonic acid, Phenylsulfonic acid etc.
Only contain a kind of functional group of the same type in the molecular structure of above-mentioned all class solidifying agent, as amine (NH
2) basic, acid amides (CONH
2) basic, sulfonic acid (SO
3H) base or SULPHURYL CHLORIDE (SO
2Cl) base etc., and these single functional groups only can have an effect and demonstrate its distinctive sense at a kind of (class) resin, and just can not have an effect to inhomogeneous resin.In other words, has amine (NH
2) base and or acid amides (CONH
2) solidifying agent of base class functional group, can only play solidification to Resins, epoxy, and have sulfonic acid (SO
3H) base and or SULPHURYL CHLORIDE (SO
2Cl) solidifying agent of base class functional group can only play solidification to resol and furane resin.
96116848.X application for a patent for invention is exactly to exist at above-mentioned all solidifying agent to have only unitary class functional group and can only a kind of resin be played the defective of solidification and propose to have in a kind of solidifying agent the above inhomogeneity of two or two functional group, makes it to have the multifunctional resin curing agent that can both have an effect with Resins, epoxy, resol, furane resin or their mixture.
The objective of the invention is on the basis of 96116848.X application for a patent for invention, increase A stage resol or furane resin component, make further raising curing activity, reduce cost, save material, propose a kind of Multifunction resin curing agent (II).
Principle of the present invention is based on the amine (NH that can play solidification with Resins, epoxy in the curing activity body molecular structure that makes in a kind of multifunctional resin curing agent
2) basic functional group and or acid amides (CONH
2) basic functional group, the sulfonic acid (SO that can play solidification with resol or furane resin is arranged again
3H) basic functional group also has A stage resol or furane resin composition.Curing activity body in this class multifunctional resin curing agent (II) has the organic compound of structure shown in the following general formula (I):
