Abstract
The process of producing semi-finished paint self-dried alkyd resin with sewage ditch oil includes heating sewage ditch oil and monoacid in the pot to 70-90 deg.c and adding assistant, dewatering before heating to 140-160 deg.c slowly, adding maleic anhydride, heating to 240-260 deg.c in 1.5-3.0 hr to acidolyze sewage ditch oil, cooling to 180-200 deg.c and adding polyol, polybasic acid and reflux solvent, heating to and maintaining at 180-200 deg.c, heating to and maintaining at 240-250 deg.c to dewater, heating to 270-290 deg.c to polymerize to reach required acid number and viscosity, cooling and adding solvent to dilute, filtering at 100 deg.c and packing. The present invention is environment friendly.
Description
One, technical field
The present invention relates to the fine chemical technology field, particularly the production method of coating work in-process Synolac.
Two, background technology
Synolac employing vegetables oil or vegetable oil acid and polyvalent alcohol and polyprotonic acid are polymerized in the prior art, because the cost of material height makes product cost high.Http:// www.asia-coating.cn/xwzx/ShowArticle.asp? Article ID=744 (update time: 2006-11-7) disclose and a kind ofly replace soya-bean oil, tung oil, linseed oil wet goods vegetables oil with sewer oil and waste vegetable oil residue, replace solvent with the waste water in the production process, produce the residue of PTA, useless glycerine replacement polyvalent alcohol, synthetic aqueous alkide resin with the chemical plant; This method is a raw material because of adopting cheap sewer oil and waste vegetable oil residue, production cost is obviously reduced, but because of the unsettled reason of sewer oil iodine number, its hardness of synthetic aqueous alkide resin product and dryness are relatively poor, glossiness is bad, weather resisteant is poor, and easy layering or freeze and be difficult for storing when the storage time is longer.
Three, summary of the invention
The purpose of this invention is to provide that a kind of production cost is low, the production method of the stable and reliable product quality Synolac that particularly hardness and dryness are good.
In order to realize above purpose, the present invention utilizes sewer oil to produce Synolac and has adopted that to introduce the double key number that the cis-butenedioic anhydride molecule carries out acidolysis to sewer oil and utilize two keys of cis-butenedioic anhydride to improve sewer oil in sewer oil be the principle of iodine number, it is raw material with the sewer oil, with monoprotic acid, auxiliary agent, polyvalent alcohol, polyprotonic acid, reflux solvent and diluting solvent is subsidiary material, synthetic alkyd resin, its operation steps is:
The first step: sewer oil, monoprotic acid are dropped in the pot adding assistant when being warming up to 70-90 ℃, processed;
Second step: slowly be warming up to 140-160 ℃ and add cis-butenedioic anhydride, the adding weight ratio is a sewer oil: cis-butenedioic anhydride=20:(0.3-1), be warming up to 240-260 ℃ through 1.5-3.0 hour and carry out the sewer oil acidolysis and increase the key reaction;
The 3rd step: temperature is adjusted downward to 180-200 ℃ adds polyvalent alcohol, polyprotonic acid and reflux solvent, and successively be warming up to 180-200 ℃ and 240-250 ℃ of insulation esterification dehydration;
The 4th step: be warmed up to 270-290 ℃ of polymerization;
The 5th step: acid number, viscosity qualified back cooling, add the diluting solvent latting drown, filtering and packaging below 100 ℃.
Because sewer oil is the mixture of various vegetable and animals oils, and to a certain degree corrupt hydrolysis often arranged, make the acid number and the iodine number of sewer oil very unstable, so utilize sewer oil production from dry alkyd resin, must solve the low problem of its iodine number, the present invention is by introducing the cis-butenedioic anhydride molecule in sewer oil, and the double key number that utilizes two keys of cis-butenedioic anhydride to improve sewer oil is an iodine number, can guarantee to produce good from the dry alkyd resin dryness, hardness is high, stable and reliable product quality.
In sewer oil, introduce the acidolysis of cis-butenedioic anhydride and increase key and react and carry out synchronously, its reaction equation following (R ', R ", R_ is aliphatic group):
That is:
The maximum usage quantity of sewer oil of the present invention accounts for 35% of amount of resin, and promptly synthetic 1 ton of resin can digest the 350kg sewer oil, can make from the dry alkyd resin cost and significantly reduce about 20%.On the other hand, reclaiming sewer oil turns waste into wealth, and helps eliminating pollution of dining table, has environmental benefit.
Four, embodiment
Below in conjunction with specific embodiment the present invention is described in further detail.
Embodiment:
A. utilize sewer oil to produce the Synolac formula for raw stock: to make polyvalent alcohol, phthalic anhydride with tetramethylolmethane and do that polyprotonic acid, dimethylbenzene are made reflux solvent, talloleic acid is made monoprotic acid, 200
