Abstract
The invention discloses low-cost drying alkyd resin prepared from discarded edible oil. The alkyd resin is prepared from the following raw materials in parts by weight of 15-35 parts of discarded edible oil, 8-15 parts of polyhydric alcohols, 0.01-0.02 part of catalyst, 12-20 parts of binary acid or anhydride and 45-55 parts of diluent. Compared with the prior art, the low-cost drying alkyd resin has the advantages that the discarded edible oil with low price is adopted to replace the vegetable oil or vegetable oil acids used in the traditional formula to prepare the alkyd resin, the cost of per ton of the low-cost drying alkyd resin can be reduced by about 1500yuan, and the property of the low-cost drying alkyd resin is not lower than that of an existing product.
Description
Technical field
The present invention relates to a kind of Synolac, be specifically related to a kind of low-cost drying-type Synolac and application of adopting discarded edible oil preparation.
Background technology
Synolac is the fatty acid modified vibrin of a kind of usefulness, and wherein fatty acid content is 30～75wt%, is one of important foundation resin of coatings industry.Synolac can be divided into two types of air drying type and drying-types according to drying mode.Traditional Synolac mainly adopts dry vegetable oil or the vegetable oil acid that oleum lini, Viscotrol C, soya-bean oil, Chinese catalpa oil, tung oil etc. contain a large amount of unsaturated link(age)s to introduce lipid acid.Oxidation cross-linked reaction mainly takes place by the unsaturated link(age) in the lipid acid and forms the solid paint film in the air drying type Synolac under the effect of siccative.The drying-type Synolac then needs to be used with cross-linked resins such as aminoresin, urethane resins, the polycondensation crosslinking reaction that takes place during by high bake changes the solid paint film into, its drying property depends primarily on the cross-linked resin that cooperates with it, and be not the unsaturated link(age) that depends in the lipid acid, therefore when preparation drying-type Synolac, can adopt the lower low iodine number grease of price to substitute dry vegetable oil or vegetable oil acid, thereby reduce manufacturing cost.
Discarded edible oil is the grease that people discard in food and drink and food processing process, is commonly called as sewer oil, hogwash fat, swill oil, old oil, leftover bits and pieces wet goods, reclaims cheap.Contain various impurity in the discarded edible oil crude product that reclaims, as moisture, solid matter, colloid mucus, free fatty acids, protein, the unsaturated fatty acids acid oligomer, superoxide etc., according to different sources, though the composition of impurity and content have very big difference, but through dehydration, filter, come unstuck, decolouring, after the refining step simple process such as deodorization, its main component is Witepsol W-S 55, free fatty acids and unsaturated fatty acids acid oligomer, content has reached more than 98%, iodine number need not further processing and can be directly used in the preparation Synolac between 70～110g/100g.Adopt cheap discarded edible oil, not only can reduce the manufacturing cost of Synolac, can also be worth by the recycling that improves discarded edible oil, the discarded edible oil of guiding leaves dining table, has important society and economic benefit.Yet also there is not to adopt the drying-type Synolac of discarded edible oil preparation at present on the market.
Summary of the invention
The objective of the invention is at above-mentioned the deficiencies in the prior art, a kind of low-cost drying-type Synolac that adopts discarded edible oil preparation is provided.
Technical scheme of the present invention:
A kind of drying-type Synolac, its preparation raw material comprises the composition of following weight part: 45～55 parts of 15～35 parts of discarded edible oils, 8～15 parts of polyvalent alcohols, 0.01～0.02 part of catalyzer, diprotic acid or 12～20 parts on acid anhydrides and letdown solvent duns.
Described discarded edible oil is one or more in discarded sewer oil, hogwash fat, swill oil, old oil and the garbage grease that produces in catering trade and food processing process.
Described polyvalent alcohol is one or more in glycerine, tetramethylolmethane, TriMethylolPropane(TMP), ethylene glycol, glycol ether, triglycol and the propylene glycol.
Described catalyzer is one or more in lithium hydroxide, naphthenic acid lithium, calcium oxide and the calcium hydroxide.
Described diprotic acid or acid anhydrides are one or more in m-phthalic acid, terephthalic acid, Tetra hydro Phthalic anhydride, MALEIC ANHYDRIDE and the FUMARIC ACID TECH GRADE acid anhydride.
Described letdown solvent dun is one or more in toluene, dimethylbenzene, No. 200 solvent oils, No. 190 solvent oils, ethyl acetate, ethylene glycol monomethyl ether and the ethylene glycol ethyl ethers.
The production technique of the production technique of drying-type Synolac of the present invention and general Synolac does not have essential distinction, comprising: operations such as alcoholysis, esterification, polycondensation, dilution.
The process for refining of the process for refining of the used discarded edible oil of the present invention and general discarded edible oil does not have essential distinction, comprising: dewater, come unstuck, operation such as filtration, decolouring, deodorization.
Synolac of the present invention is mainly used in coating such as the various drying-type alkyd varnishes of preparation, synthetic enamel, alkyd coating varnish.
Compared with prior art, drying-type Synolac of the present invention is owing to adopt cheap discarded edible oil to substitute vegetables oil or vegetable oil acid that conventional formulation is used, average product per ton can reduce cost about 1500 yuan, and adopt Synolac of the present invention to cooperate institute's coatings formulated with cross-linked resins such as aminoresin, urethane resins, the performance of gained paint film is not less than currently available products.
Embodiment
Embodiment:
Be example with preparation 1000kg drying-type Synolac of the present invention below, its preparation parts by weight of raw materials is: 50.5 parts of 27 parts of discarded edible oils (sewer oil 270kg), 11.5 parts of polyvalent alcohols (tetramethylolmethane 62kg+ glycol ether 53kg), 0.012 part of catalyzer (lithium hydroxide 0.12kg), diprotic acid or 16 parts on acid anhydrides (Tetra hydro Phthalic anhydride 160 kg) and letdown solvent duns (No. 200 solvent oil 200kg+ dimethylbenzene 305kg).
