Abstract
The invention discloses a kind of dicyandiamide based epoxy resin curing formula, belong to chemical material field.It is made up of following raw material: TDE 85 type liquid-state epoxy resin 100 120 parts, dimethylaniline modified dicyandiamine 45 58 parts, 2 ethyl 4 Methylimidazole .s 0.5 0.9 parts, phosphite ester 0.3 0.5 parts, dehydrated alcohol 30 50 parts.The dicyandiamide based epoxy resin curing formula of the offer of the present invention, the storage-stable time is permanent, and applied range is suitable for modern industry large-scale production.
Description
Technical field
The present invention relates to chemical material field, be specifically related to a kind of dicyandiamide based epoxy resin curing formula.
Background technology
Dicyandiamide, also known as dicyanodiamine, is the thermal activities latent curing agent the most often used, applies the most widely
In fields such as powdery paints, adhesive monocomponent adhesive, film glue and glass cloth laminated boards.Dicyandiamide and epoxy resin
After mixing, its micropowder is distributed in epoxy resin, and condition of cure is (160-180 DEG C)/(60-20min), storage in room temperature
As long as phase is up to half a year.The curing mechanism of dicyandiamide is more complicated, and in addition to four hydrogen on dicyandiamide can participate in reaction, cyano group also has
There is certain reactivity.
It is the highest that dicyandiamide is used alone as solidification temperature during epoxy curing agent, solidification temperature typically 160-180 DEG C it
Between, many devices and material can not use owing to can not bear such temperature at this temperature, or because production technology
Require and the solidification temperature of one-component epoxy resin must be reduced.The method solving this problem has two kinds, and a kind of method is to add
Enter accelerator, on the premise of the storage period and serviceability of infringement dicyandiamide not too much, reduce its solidification temperature；Another kind side
Method is, by the method for MOLECULE DESIGN, dicyandiamide is carried out chemical modification.
Summary of the invention
For above-mentioned, it is an object of the invention to provide a kind of dicyandiamide based epoxy resin simultaneously using two kinds of solutions
Curing formula.
The concrete technical scheme that the present invention takes is:
A kind of dicyandiamide based epoxy resin curing formula, it is characterised in that by weight, be made up of following raw material: TDE-
85 type liquid-state epoxy resin 100-120 parts, dimethylaniline modified dicyandiamine 45-58 part, 2-ethyl-4 Methylimidazole. 0.5-0.9
Part, phosphite ester 0.3-0.5 part, dehydrated alcohol 30-50 part.
The invention have the advantage that the storage-stable time permanent, applied range, it is suitable for modern industry large-scale production.
Detailed description of the invention
Below presently preferred embodiments of the present invention is described in detail so that advantages and features of the invention can be easier to by
It will be appreciated by those skilled in the art that thus protection scope of the present invention is made apparent clear and definite defining.
