Abstract
The invention aims to provide a production technology of an ABS resin, particularly relates to an all-continuous high-safety emulsion grafting blending method for production of the ABS resin, and belongs to the technical field of ABS resin production. The production technology comprises the following processes: a continuous process comprising contentious production of PB latex with large particle, graft polymerization, condensation and centrifugation to obtain a grafted wet powder; a production process for continuous production of SAN (styrene-acrylonitrile) particle; and a process for producing ABS resin by continuous blending of the wet powder obtained by grafting the PB latex with large particle with SAN (styrene-acrylonitrile) particle. The production can achieve rapid synthesis, rapid particle expansion and continuous graft polymerization of PB latex, condensation, dehydration and wet powder mixing extrusion to produce ABS resin, increase the utilization rate of equipment and yield of ABS resin, reduce energy consumption and material consumption, improve product quality and product appearance, simplify the production process of emulsion method for production of ABS, reduce the investment and eliminate unsafe factors such as inflammation and explosion during drying of wet powder.
Description
Technical field
The present invention relates to a kind of production technique of ABS resin, particularly a kind of full production technique of high safe emulsion graft polymerization blending legal system ABS resin continuously belongs to the production technical field of ABS resin.
Background technology
The mainstream technology that the ABS of the world today makes has two classes, and one is for being continuous bulk, its two emulsion graft polymerizations blending method.
Continuous bulk essence is special solution grafting, and this method does not have waste water, but its product grade is few, poor performance.
Emulsion graft polymerization blending method product grade is many, good product performance.But this method still is interrupter method so far, and more waste water is arranged, a small amount of waste residue, waste gas, and plant factor is not high.Charging, discharging time account for the 20-30% of operating time, and the boring energy of waste is more.
At the problems referred to above, the present inventor has proposed a kind of new technical matters, has solved the problems referred to above well.
Summary of the invention
The production technique that the purpose of this invention is to provide a kind of ABS resin, be particularly related to a kind of full production technique of high safe emulsion graft polymerization blending legal system ABS resin continuously, this production technique comprises the technology of the PB latex grafting wet-milling of the big particle diameter of continuous making, makes SAN(vinylbenzene-vinyl cyanide continuously) manufacture craft of particle and the PB latex grafting wet-milling of big particle diameter be with SAN(vinylbenzene-vinyl cyanide) the continuous blending of particle produces the technology of ABS resin.
One, it is as follows to make the technical scheme of PB latex grafting wet-milling of big particle diameter continuously:
The first step, preparation small particle size PB latex are with the PB latex of divinylic monomer and water and auxiliary agent continuously synthetic small particle size under temperature is 40-80 ℃;
Second step, the big particle diameter PB latex of preparation are to enlarge the PB latex that particle diameter becomes big particle diameter continuously under 17-60 ℃ the condition in temperature with small particle size PB latex;
The 3rd step, be to carry out continuous graft polymerization with vinylbenzene and vinyl cyanide under 30-80 ℃ the condition in temperature with the PB latex of big particle diameter;
The 4th step, be to condense formation suspension continuously under 30-100 ℃ the condition in temperature through the graft emulsion of continuous graft polymerization;
The 5th step, suspension carry out continuously dehydrating at normal temperatures and form the grafting wet-milling.
Two, make SAN(vinylbenzene-vinyl cyanide continuously) technical scheme of particle is as follows:
The first step, St, AN and solvent synthesize SAN(vinylbenzene-vinyl cyanide at normal temperatures continuously);
Second step, to SAN(vinylbenzene-vinyl cyanide) body carries out continuous granulation.
Three, the PB latex grafting wet-milling of big particle diameter is with SAN(vinylbenzene-vinyl cyanide) the continuous blending of particle in temperature be under 200-250 ℃ the condition continuously extruding pelletization produce the ABS resin product.
Adopt this production technique can realize PB latex fast synthetic, fast enlarge particle diameter and graft polymerization continuously, cohesion, centrifuge dehydration, wet-milling blending extrude ABS resin, improve plant factor, improved output, energy consumption, material consumption have been reduced, simplify the technical process that emulsion method is produced ABS, reduced investment, eliminated the unsafe factor that the wet-milling drying is caught fire and exploded, improve quality product, improved product appearance.
