Abstract
The invention discloses an epoxy resin curing agent. The epoxy resin curing agent is prepared from the following components in parts by weight: 40-60 parts of acid-anhydride mixture, 20-25 parts of aluminum oxide, 15-30 parts of isoprene, 10-25 parts of n-butyl alcohol-water glyceryl ether, 8-15 parts of asbestos fiber and 10-15 parts of diluent. The epoxy resin curing agent provided by the invention has high curing reaction speed, and the complete curing time of epoxy resin can be shortened.
Description
Technical field
The disclosure relates generally to technical field of coatings, is specifically related to epoxy resin, particularly relates to ring
Epoxy resins firming agent.
Background technology
Epoxy resin is a kind of amorphous thick liquid, and heating, in plasticity, does not has obvious fusing point,
It is heated deliquescing, gradually fusing and stickness, water insoluble, itself will not harden, therefore it is almost
There is no single use value.Epoxy curing agent is and epoxy resin generation chemical reaction,
Form netted space polymers, composite aggregate envelope among reticulate body, make line style tree
Fat becomes the additive of tough and tensile build solid.After epoxy resin adds a certain amount of firming agent,
The most gradually solidify.
Owing to having good mechanical strength and insulating properties, epoxy resin after epoxy resin cure
It is widely used in the manufacture of electronic product as bonding agent, needs epoxy as on circuit board
Resin carries out adhesive curing together to some electrical equipments.But due to epoxy resin at normal temperatures
(28 DEG C) are long for hardening time, typically just can be fully cured at 8-12 hour, have a strong impact on work
Make efficiency.
Summary of the invention
In view of drawbacks described above of the prior art or deficiency, it is desirable to provide one to reduce at normal temperatures
The epoxy curing agent of the hardening time of epoxy resin.
The epoxy curing agent that the present invention provides, including each component of following parts by weight: acid
Acid anhydride mixture 40-60 part, aluminium oxide 20-25 part, isoprene 15-30 part, n-butyl alcohol water
Glycerin ether 10-25 part, asbestos fibre 8-15 part and diluent 10-15 part.
The epoxy curing agent curing reaction speed that the present invention provides is fast, it is possible to decrease epoxy resin
The completely crued time was to 5.2 hours.
