Abstract
A kind of post-processing approach of polyester acrylate, comprising the following steps: S1: polyester acrylate, solvent are added in kettle；S2: the first salting liquid is added, is transferred in separatory funnel and stands after being sufficiently stirred, discard lower water；S3: the second salting liquid is added, is transferred in separatory funnel and stands after being sufficiently stirred in ice-water bath, discard lower water；S4: removing solvent, filtering and discharging are vacuumized.By the polyester acrylate that the post-processing approach obtains, there is solvent-free, no acid value, the characteristic of high-purity is suitable for the higher occasion of material requirements.
Description
Technical field
The present invention relates to chemical fields, more particularly, to a kind of post-processing approach of polyester acrylate.
Background technique
UV-curing technology is a kind of efficient, energy-saving and environmental protection, good surface treatment technology of material.Its solidification rate
It is current various coating, ink, most fast in adhesive, is able to satisfy the automated production requirement of large-scale pipeline, photocuring
Product is applicable to a variety of substrates such as paper, metal, plastics, glass, timber.Without volatile solvent, reduce to environment and
The harm of human body.Attention with countries in the world to atmosphere discharge VOC, the superiority of photocuring product seem more prominent.
Polyester acrylate is a kind of common photo curable oligomer.The polyester acrylate of low-viscosity can be used as
Oligomer also can be used as reactive diluent use.Compared with conventional single-activity diluent, polyester acrylate can basis
Use demand adjusts the structure of polyester portion, brings more changeable performance and more flexible use space.
Existing polyester acrylate synthetic method be usually reacted direct discharging, or react except after solvent out
Material.This method can remain the auxiliary agents such as reacting middle catalyst antioxidant and remaining acrylic acid.After the prior art does not have also suitably
Processing method.
Summary of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of post-processing approach of polyester acrylate.
The technical solution of the present invention is as follows:
A kind of post-processing approach of polyester acrylate, comprising the following steps:
S1: polyester acrylate, solvent are added in kettle；
S2: the first salting liquid is added, is transferred in separatory funnel and stands after being sufficiently stirred, discard lower water；
S3: the second salting liquid is added, is transferred in separatory funnel and stands after being sufficiently stirred in ice-water bath, discard lower water；
S4: removing solvent, filtering and discharging are vacuumized.
Further, in the step S1, solvent is toluene.
Further, in the step S1, the weight proportion of polyester acrylate and solvent is 1:2.
Further, in the step S2, the first salting liquid is 15% sodium chloride solution.
Further, in the step S3, the second salting liquid is the mixed solution of 10% sodium chloride and 10% ammonium hydrogen carbonate.
The invention has the following advantages that there is solvent-free, anacidity by the polyester acrylate that the post-processing approach obtains
Value, the characteristic of high-purity are suitable for the higher occasion of material requirements.
Specific embodiment
The preferred embodiments of the present invention will be described in detail below, so that advantages and features of the invention are easier to by this field skill
Art personnel understand, to make apparent define to protection scope of the present invention.
Embodiment 1
Four-hole boiling flask is added in 50g polyester acrylate, 100g toluene, the sodium chloride solution of 15g15% is added, is sufficiently stirred, turns
Enter and discards lower water after standing in separatory funnel.20 DEG C of temperature < are kept in ice-water bath, and 20g10% sodium chloride and 10% carbon is added
The mixed solution of sour hydrogen ammonium, is sufficiently stirred, and is transferred to after standing in separatory funnel and discards lower water.Resulting material is in vacuum degree-
0.1MPa distills at 95 DEG C, obtains colorless and transparent clarification sample, acid value 0.03mgKOH/g by suction filtration, viscosity is
14300Pas (25 DEG C), total solvent content are 235ppm, ester content 98.7%.
The above embodiment is a preferred embodiment of the present invention, but embodiments of the present invention are not by the embodiment
Limitation, other any changes, modifications, substitutions, combinations, simplifications made without departing from the spirit and principles of the present invention,
It should be equivalent substitute mode, be included within the scope of the present invention.
