Abstract
The invention relates to a modified fatty amine curing agent. The fatty amine curing agent has the characteristics of room temperature curing, colorless transparence, low viscosity, mild heat release in curing, convenient use and the like. Through modification, the curing agent has increased molecular weight, small volatility and low toxicity, and the toughness, the electric insulation, the medium resistance and the use safety of the curing agent are greatly improved. The fatty amine curing agent is prepared by steps of mixing and preparing diethylene amine and benzyl alcohol according to a certain proportion and sequence, and the like.
Description
Technical field:
The present invention relates to a kind of modified fatty amine curing agent, particularly a kind of modified fatty amine curing agent.
Prior art:
Resins, epoxy be with become the field in an important kind, because it has a series of good performances, strong as cohesiveness, shrinking percentage is little, mechanical property, dielectric properties and fine heat-resisting performance, good chemical stability is so be widely used in electronics, electrical equipment, machinery, chemical industry, civil engineering work, national defence and other the many production fields.Adopt Resins, epoxy can make numerous high-performance coatings, as cathode electrodeposition priming paint, powder coating, food cans and soft drink can inner-wall paint, boats and ships and heavy anticorrosion turbid coating, industry ground slab coating, insullac etc.Solidifying agent has very high reactive behavior, but normal temperature and low-temperature curing, advantage such as it is low to have viscosity, and chemical property is good, but its following again weak point: 1. solidifying is that thermal discharge is big, and once joining lacquer can not be too many, the construction time limit is short.2. volatile, frowziness and pungency influence operator's health.
Summary of the invention:
The purpose of this invention is to provide a kind of modified fatty amine curing agent, he has overcome the shortcoming of above-mentioned aliphatic amide, has the solidifying agent molecular weight and increases, and volatility is little, the advantage that toxicity is low.
The object of the present invention is achieved like this: be by the rare triamine of diethyl, Resins, epoxy, phenylcarbinol are formed, and each per-cent two is different to be triamine 35%-50%, Resins, epoxy 10%-20%, phenylcarbinol 30%-50%
A kind of modified fatty amine curing agent is characterized in that realizing by following step:
The first step: in the there-necked flask of band whipping appts and thermometer, add Resins, epoxy of 10-20 part and the phenylcarbinol of 22-38 part.Start stirring, material is heated to 40 ℃.Stand-by.
Second step: in the four-hole bottle of band whipping appts, thermometer and constant pressure funnel, add two different rare triamines of 35-48 part and the phenylcarbinol of 10-25 part.Start stirring, material is heated to 40 ℃.The material of the first step gained added by constant pressure funnel react, the control rate of addition makes and is reflected at 40 ℃ and carries out, and dropwises in 2 hours.
The 3rd step: continue at 40 ℃ of reactions 1 hour, cooling discharge.
Modified fatty amine curing agent of the present invention is by carrying out addition reaction with Resins, epoxy and the rare triamine of diethyl, and the family that obtains aliphatic amide becomes thing, thereby has reduced the toxicity of solidifying agent, has improved the consistency with Resins, epoxy.Add phenylcarbinol and play the effect that reduces viscosity as non-activated thinner and softening agent.Its main performance index is: and viscosity (25 ℃, mPa.s) 100-800, amine value (mgKOH/g) 500-600.
Specific embodiment:
Below in conjunction with specific embodiment the present invention is described in further detail.
Embodiment 1:
In the there-necked flask of band whipping appts and thermometer, adds 15 parts Resins, epoxy and 30 parts phenylcarbinol, begin stirring, with material be heated to 40 ℃ stand-by.In the four-hole bottle of another band whipping appts, thermometer and constant pressure funnel, add 40 parts two different rare triamines and 18 parts phenylcarbinol.Start stirring, material is heated to 40 ℃.Then the material in the aforementioned there-necked flask is added by constant pressure funnel and reacted, the control rate of addition makes and is reflected at 40 ℃ and carries out, and dropwises in 2 hours.Continuation is at 40 ℃ of reactions 2 hours, cooling discharge.Products therefrom is colourless or the light yellow clarifying liquid body, and viscosity (25 ℃, mPa.s) 180-420, amine value (mgKOH/g) 500-600.
Claims (3)
1. be by the rare triamine of diethyl, Resins, epoxy, phenylcarbinol are formed, and each per-cent two is different to be triamine 35%-50%, Resins, epoxy 10%-20%, phenylcarbinol 30%-50%.
2. require 1 described this property fatty amine curing agent as claims, it is characterized in that Resins, epoxy is bisphenol-A liquid epoxy resin.
3. modified fatty amine curing agent is characterized in that realizing by following step:
The first step: in the there-necked flask of band whipping appts and thermometer, add Resins, epoxy of 10-20 part and the phenylcarbinol of 22-38 part.Start stirring, material is heated to 40 ℃.Stand-by.
Second step: in the four-hole bottle of band whipping appts, thermometer and constant pressure funnel, add two different rare triamines of 35-48 part and the phenylcarbinol of 10-25 part.Start stirring, material is heated to 40 ℃.The material of the first step gained added by constant pressure funnel react, the control rate of addition makes and is reflected at 40 ℃ and carries out, and dropwises in 2 hours.
The 3rd step: continue at 40 ℃ of reactions 1 hour, cooling discharge.
