Abstract
The invention relates to a colorless rosin modified resin and a production method thereof. The production method comprises the following steps of: A. dissolving special-grade rosin, and carrying out preliminary distillation in vacuum; B. heating the material subjected to preliminary distillation, carrying out middle distillation in vacuum; C. feeding the material subjected to the middle distillation to a reaction kettle, adding 6-tertinary butyl-3-methylphenol, and carrying out steam blowing and vacuum dehydration; D. adding a stabilizing agent compounded by di-tert-butyl p-methyl phenol and phosphite ester after heating, opening cooling water of a condenser, dropwise adding glycerol, carrying out esterification reaction after heating, and taking a sample for testing an acid value; E. blowing the resin in the kettle by using a steam jet after the tested acid value is qualified; F. carrying out vacuum dehydration with roots after completing blowing; and G preparing nitrogen for protection, cooling, pelleting and packaging. According to the production method, heavy oil and black fragrance can be further removed through the secondary distillation in vacuum so that the original pale rosin modified resin turns into the true colorless rosin modified resin.
Description
Technical field
The present invention relates to a kind of colourless modified rosin resin and production method thereof.
Background technology
So-called colourless modified rosin resin in the market still has light color, still can not meet the fields such as some medicine, daily-use chemical industry.
Summary of the invention
The object of this invention is to provide the colourless modified rosin resin of one and the production method thereof that can reach colourless completely.
The technical scheme that the present invention takes is: a kind of colourless modified rosin resin, is characterized in that its composition by weight is: 0~0.3 kilogram of stablizer, 0.5~0.8 kilogram of 6-tertiary butyl-3-methylphenol that superfine rosin 95~double centner, 10~15 kilograms of glycerine, ditertbutylparacresol and phosphorous acid ester are compound.
The production method of described a kind of colourless modified rosin resin, it is characterized in that it comprise the following steps: A, by superfine rosin dissolve after, enter still kettle and be with vacuum distilling to carry out fore-running at 200 ℃~210 ℃ temperature; B, the material after fore-running is heated to the vacuum distilling of 275 ℃ ± 10 ℃ bands and heated up in a steamer in carrying out; C, by send into reactor after material dissolution after heating up in a steamer, add 6-tertiary butyl-3-methylphenol, when temperature reaches 190 ℃~200 ℃, with steaming out 30 minutes, vacuum hydro-extraction 0.5 hour; D, temperature rise to 220 ℃~230 ℃ and add ditertbutylparacresol and the compound stablizer of phosphorous acid ester, open condenser cooling water, drip glycerine, and after temperature rises to 265 ℃, constant temperature carries out esterification sample examination acid number after 6 hours; E, chemical examination acid number are qualified purges in still resin 1 hour afterwards with steam jet; F, purge complete again with Roots vacuum dehydration 3 hours; G, nitrogen protection processed, cooling, granulation, packing.
Adopt the present invention, can, further but except heavy oil and black perfume (or spice), make original pale rosin modified resin become real colourless modified rosin resin by band vacuum second distillation.
Embodiment
Below in conjunction with specific embodiment, the invention will be further described.The production method of this colourless modified rosin resin comprises the following steps:
One, after superfine rosin 95~100 is dissolved, enter still kettle and be with vacuum distilling to carry out fore-running at 200 ℃~210 ℃ temperature, remove wherein heavy oil;
Two, the material after fore-running is heated and in the vacuum distilling of 275 ℃ ± 10 ℃ bands is carried out, heat up in a steamer, remove black perfume (or spice) wherein;
Three, by through in send into reactor after material dissolution after heating up in a steamer, temperature reaches 190 ℃~200 ℃, with steaming out 30 minutes, vacuum hydro-extraction 0.5 hour;
Four, add 0~0.3 kilogram of ditertbutylparacresol when temperature rises to 220 ℃~230 ℃, open condenser cooling water, drip glycerine 10~15, after temperature rises to 265 ℃, constant temperature carries out esterification sample examination acid number after 6 hours;
Five, chemical examination acid number is qualified purges in still resin 1 hour afterwards with steam jet;
Six, purge complete again with Roots vacuum dehydration 3 hours.
In above-mentioned, can, further but except heavy oil and black perfume (or spice), make original pale rosin modified resin become real colourless modified rosin resin by band vacuum second distillation.
