Abstract
The invention provides an alkyd resin of a rice bran oleic acid. The alkyd resin of the rice bran oleic acid is prepared from the following components in parts by weight: 30-39 parts of rice bran oleic acid, 27-33 parts of purified terephthalic acid, 22-30 parts of glycerinum, 4-10 parts of phthalic anhydride and 0.08-0.12 part of butyltin. The alkyd resin is simple in preparation process, a soya oil acid is replaced with the rice bran oleic acid, most of phthalic anhydride is replaced with the purified terephthalic acid, and the alkyd resin is accompanied by scientific proportion and process, so that not only is the production cost greatly reduced, but also the performance is excellent.
Description
Technical field
The present invention relates to a kind of Baking Paint Synolac, particularly one utilizes renewable resources oleic acid to prepare Baking Paint Synolac, also relates to the preparation method of this Synolac.
Background technology
A lot of for the Synolac of Baking Paint, it is obtained by polyvalent alcohol and polyprotonic acid, lipid acid (or vegetables oil) polycondensation; Change kind and the relative consumption of various alcohols and acids, can make the Synolac of a series of different varietiess.Because raw material sources are extensive, production technique is relatively simple, the market requirement is large again, so all there is production in domestic a lot of producer, thereby the fierceness of constituting competition, is all ensureing under the prerequisite of quality product by every means, finds novel material, novel process to reduce production costs, participate in the competition, in the hope of occupying a tiny space on market.
Oleic acid is the renewable resources that a kind of amount is large and wide, and it derives from the byproduct rice bran in paddy processing.In rice bran, contain the Rice pollard oil of 12-20%, its main component is the glyceride of oleic acid, linolic acid and Zoomeric acid.In the time that storing, rice bran to carry out in time glyceridase purification process (domestic a lot of medium and small paddy processing spaces do not do purification process), if process not in time, glyceridase in rice bran will be had an effect, especially when long at rice bran storage time or storing temp is high, enzyme activity is stronger, and the rice bran crude oil acid number of producing is very high, even reaches 30-50mg KOH/g, substantially exceed the national standard of food oils rice bran crude oil, cannot be for the production of edible oil.The Rice pollard oil that this acid number is very high, generally be referred to as the oil that becomes sour, with this oil that becomes sour through hydrolysis, rectifying just can produce oleic acid, iodine number 92-109, acid number 182-191, color 5-6# (fe-Co colorimetric), price 6100-6300 yuan/ton are lower more than 2000 yuan than soya-bean oil or behenic acid.
Summary of the invention
Goal of the invention: in order further to reduce the preparation cost of prior art Synolac, the object of this invention is to provide the Baking Paint Synolac and preparation method thereof that utilizes renewable resources oleic acid to prepare.
Technical scheme: a kind of oleic acid Synolac provided by the invention, at least made by the component of following weight part: oleic acid 30-39 part, pure terephthalic acid 27-33 part, glycerine 22-30 part, phthalic anhydride 4-10 part, butyl tin 0.08-0.12 part.
Preferably, described oleic acid Synolac is at least made up of the component of following weight part: oleic acid 32-38 part, pure terephthalic acid 28-32 part, glycerine 24-28 part, phthalic anhydride 6-8 part, butyl tin 0.09-0.11 part.
Further preferably, described oleic acid Synolac is at least made up of the component of following weight part: 35 parts of oleic acids, 30 parts of pure terephthalic acids, 26 parts of glycerine, 7 parts of phthalic anhydrides, 0.10 part of butyl tin.
The present invention also provides the preparation method of above-mentioned oleic acid Synolac, comprises the following steps:
(1), under 210-225 DEG C (preferably 215-220 DEG C), under catalyzer butyl tin exists, oleic acid, pure terephthalic acid, glycerine esterification reaction are to transparent; Temperature is low, can make extend reaction time, and excess Temperature, although can shorten the production cycle, can make to control difficulty;
(2) be cooled to 195-205 DEG C (preferably 200 ± 2 DEG C), add phthalic anhydride, insulation esterification is to viscosity 20-30 second/lattice, acid number below 10, and cooling, to obtain final product; The too high meeting of temperature causes gel.
Wherein, each ingredients weight parts is respectively: oleic acid 30-39 part, pure terephthalic acid 27-33 part, glycerine 22-30 part, phthalic anhydride 4-10 part, butyl tin 0.08-0.12 part.
Beneficial effect: oleic acid Synolac preparation technology provided by the invention is simple, replace behenic acid with oleic acid, replace most of phthalic anhydride with pure terephthalic acid, be aided with compared with the proportioning of science and technique, not only greatly reduce production cost, and excellent performance.
Particularly, Synolac of the present invention, owing to having adopted oleic acid, replaces most of phthalic anhydride with pure terephthalic acid again, be aided with the proportioning compared with science, adopt the technique of two step esterifications, not only quality product is high, the more important thing is and greatly reduce production cost, per tonly fall more than 1000 yuan.(6200 yuan/ton of oleic acids, 9200 yuan/ton, soya-bean oil, 8200 yuan/ton of behenic acids, 8650 yuan/ton of pure terephthalic acids, 11800 yuan/ton of phthalic anhydrides.)
