Abstract
The invention discloses a novel plasticizer. The novel plasticizer is prepared from diethyl phthalate, methyl methacrylate, stearic acid, benzoic acid, an adjuvant, diethylenetriamine and pentaerythritol. Through improvement of production processes and use of two different catalysts in catalytic reactions, reaction efficiency is improved. Through use of concentrated sulfuric acid and heteropoly acid as catalysts, an organic derivative is produced and final plasticizer weatherability is greatly improved. Through use of the adjuvant, plasticizer volatilization is reduced in processing and plasticizing and toughening effects of the plasticizer are improved. The novel plasticizer has the advantages of reasonable formula, low cost, low plasticizing temperature, low residual viscosity and good binding property.
Description
Technical field
The present invention relates to chemicals field, particularly relate to a kind of new plasticizer.

Softening agent has thermostability and chemical reagent stability, and the plasticity-of polymkeric substance and snappiness can be made within the specific limits to increase with polymer-compatible.Current normally used conventional weathering resistance is poor, and purposes exists obvious limitation.
Summary of the invention
The object of this invention is to provide a kind of new plasticizer.
The present invention is achieved through the following technical solutions:
A kind of new plasticizer, is made up of following composition by weight, diethyl phthalate 10 parts, methyl methacrylate 8 parts, stearic acid 6 parts, 20 parts, phenylformic acid, auxiliary 1 part, diethylenetriamine 2 parts, season amylalcohol 30 parts; It is made up of following making step:
1) by phenylformic acid, stearic acid, diethylenetriamine and season amylalcohol join in reactor and stir and heat up;
2) when temperature arrives 120-140 DEG C, add catalyzer 1, be incubated and 1-2 hour follow-up continuing be warming up to 200-220 DEG C and stir and add catalyzer 2 and carry out reaction 4-6 hour;
3) in reactor, add diethyl phthalate, methyl methacrylate and auxiliary, control temperature is to 80-90 DEG C, and pressure is 10-15MPa, and stirs, and stirring velocity is 300-350r/min, keeps 8-10 hour;
4) remove catalyzer and unreacting material, vacuum hydro-extraction with deionized water, filter.
Further, described catalyzer 1 is the vitriol oil.
Further, described catalyzer 2 is heteropolyacid.
Further, described auxiliary is made up of following composition in percentage terms: modified alta-mud 5%, hydrogen peroxide 95%.
Further, described modified alta-mud is made up of following methods: first soak wilkinite 2-3 hour with 5% sodium hydroxide solution, filter, dry, after 0.5-1 hour, wilkinite is stirred in the clear water of its 10 times of weight parts, after mixing with 300 DEG C of calcinings again, be added into the para-amino benzoic acid of wilkinite weight 1-3%, be heated to 65-80 DEG C, react after 2-3 hour, dry, be crushed to 100-150 order.
The invention has the beneficial effects as follows, compared with prior art:
The present invention passes through improvement of production process, twice different catalysts is adopted to carry out catalyzed reaction respectively, improve reaction efficiency, adopt the vitriol oil and heteropolyacid as catalyzer, catalysis can generate organic derivative in addition, the weathering resistance of the final softening agent generated can greatly be improved, by adding auxiliary, the volatilization of softening agent in the course of processing can be reduced, and can improve the plasticising toughening effect of softening agent, the present invention fills a prescription rationally, cost is low, plasticization temperature is low, residual tack is low, and binding property is good.
