Abstract
The invention discloses a method for synthesis of an acrylic emulsion modified monomer. The method comprises the steps of 1, stirring IPDI (isophorone diisocyanate) in a reaction still under normal temperature and normal pressure, and increasing the temperature to 80 DEG C while stirring; 2, placing HEMA (hydroxyethyl methylacrylate) in a titration tank, and slowly adding HEMA into the reaction still in the step 1 from the titration tank dropwise for 3 h, wherein the molar ratio of HEMA to IPDI is 2:1; 3, conducting heat insulation for 1 h at 80 DEG C after adding is completed, then reducing the temperature to 60 DEG C, and packaging and storing the discharged material, so that the acrylic emulsion modified monomer AUA, also called carbamic acid ester-carbon-carbon double bond structural monomer is obtained. The novel synthesis technology is adopted to obtain the carbamic acid ester-carbon-carbon double bond structural monomer, the monomer has the excellent physical properties of formic ether resin and the intrinsic properties of acrylate resin, cost is reduced, and usage is facilitated.
Description
Technical field
The invention belongs to chemical industry synthesis field, particularly to a kind of novel method for synthesizing for acrylic emulsion modified monomer.
Background technology
. Polyurethane resin is a kind of high molecular polymer with high intensity, high adhesion force, the wear-resisting characteristic such as by force, in field extensive uses such as daily life, industrial and agricultural production, medical science, and carbamate structures that these characteristics have with it is inseparable, but its material expensive, relatively costly.
The synthetic resin coating that acrylate resin coating is is main film forming substance with acrylate, it is shallow that this kind of coating not only has color, transparency is high, light is plentiful, weather-proof, protect color, protect light, adhesive force is strong, corrosion-resistant, hard, the feature such as pliable and tough, and can pass through to select monomer, adjust proportioning, change preparation method and change spelling resin, make a series of acrylic resin paint, but its adhesive force, intensity, the performance such as wear-resisting still has bigger gap compared with polyurethane resin, the amino-acid resin if able to a kind of acrylic resin paint of preparation can slow down, the problems referred to above just can be readily solved.
Summary of the invention
For the problem such as solve above-mentioned existing cost height, poor adhesive force, intensity difference, wear no resistance, the present invention adopts the following technical scheme that
The present invention provides a kind of synthetic method for acrylic emulsion modified monomer, including three below step: 1) at normal temperatures and pressures by IPDI(isophorone diisocyanate) stir in reactor, while stirring and heat to 80 DEG C; 2) by with the HEMA(hydroxyethyl methylacrylate that IPDI mol ratio is 2:1) be placed in titration tank, HEMA is slowly added dropwise 3 hours from titration tank in the reactor in step 1; 3) being incubated 1 hour in 80 DEG C after step 2 dropwises, be cooled to 60 DEG C afterwards, after cooling, discharging packaging preserves, and has so far just prepared required acrylic emulsion modified monomer AUA, also referred to as carbamate-carbon-carbon double bond structures alone.
The beneficial effects of the present invention is: adopt new synthetic method craft, obtain carbamate-carbon-carbon double bond structures alone, the good physical of existing polyacid ester resin, also have the proper property of acrylate concurrently, also reduce cost simultaneously, facilitate consumer to use.
Detailed description of the invention
The following detailed description of the preferred embodiments of the present invention.
A kind of synthetic method for acrylic emulsion modified monomer, including three below step: 1) at normal temperatures and pressures by IPDI(isophorone diisocyanate) stir in reactor, while stirring and heat to 80 DEG C, 2) by with the HEMA(hydroxyethyl methylacrylate that IPDI mol ratio is 2:1) be placed in titration tank, HEMA is slowly added dropwise 3 hours from titration tank in the reactor in step 1, 3) after step 2 dropwises, it is incubated 1 hour in 80 DEG C, it is cooled to 60 DEG C afterwards, after cooling, discharging packaging preserves, so far required acrylic emulsion modified monomer AUA has just been prepared, also referred to as carbamate-carbon-carbon double bond structure list, by above-mentioned new synthetic method craft, obtain the modified monomer of acrylic emulsion, acrylate is prepared by modified monomer, modified monomer is with carbamate, there are all good physical of polyacid ester resin, also have the proper property of acrylate concurrently simultaneously, in both sets of advantages to product, while function admirable, cost have also been obtained effective control, reduce use cost, really obtain inexpensive material object by technological innovation, meet the material requisite that people are growing.
The product form of above-described embodiment the non-limiting present invention and style, any person of an ordinary skill in the technical field is to its suitably change done or modifies, and all should be regarded as the patent category without departing from the present invention.
