Abstract
The invention relates to a modified alkyd resin for a corrugated case desiccant and a preparation method thereof. The modified alkyd resin for corrugated case desiccant mainly comprises soya-bean oil, glycerin, rosin, phthalic anhydride, maleic anhydride, benzoic acid, a catalyst, xylene and mineral spirits. The modified alkyd resin for the corrugated case desiccant has the advantages of high curing speed, smooth film and firmness, and has good waterproofness and humidity resistance when applied to the corrugated case.
Description
Technical field
The present invention relates to modified alkyd resin and preparation method thereof for a kind of corrugated paper box dampproof agent, belonged to packaging paper product auxiliary agent technical field.
Background technology
In all kinds of packings of Industrial products, Corrugated Box has become the main flow of packing business, because it is lightweight, collapsible, and cost is low, environmental protection, specification easily changes, can carry out high-quality printing, after recovery, can be used as renewable resources, therefore, use range is more and more wider, but it has a fatal weakness to be: carton surface easily makes moist, meet after water, physical properties index all can hurriedly decline, and when accumulating link is more severe, just needs Corrugated Box to possess certain protection against the tide, water-proof function.At present, this requirement of shelter on Corrugated Box surface, is being divided into two classes traditionally: a class is to adopt weather-proof dressing, on Corrugated Box surface, is coated with last layer non-blushing thinner; Two classes are directly to adopt waterproof packing, but this type of way packing cost is high, and user is difficult to accept.No matter adopt which kind of method all to have certain defect: if the protection against the tide having on market, water-resisting agent are because the defect that its resin quality exists itself makes protection against the tide, water resistance index is on the low side; operate in addition improper use; cause brushing inhomogeneous; be prone to localized seepage's point; the not environmental protection having or manufacturing cost are higher, are difficult to carry out the defects such as industrialized mass production.Therefore, in the urgent need to research, release a kind of Novel corrugated carton non-blushing thinner with good waterproof, humidity resistance, to meet the demand of various Corrugated Box packings.
Summary of the invention
Object of the present invention and technical problem to be solved are to provide a kind of Novel corrugated carton non-blushing thinner Synolac with good waterproof, humidity resistance,
For solving the problems of the technologies described above, the present invention is achieved through the following technical solutions, it is characterized in that this corrugated paper box dampproof agent with modified alkyd resin mainly by: soya-bean oil, glycerine, rosin, MALEIC ANHYDRIDE, Tetra hydro Phthalic anhydride, phenylformic acid, catalyzer, dimethylbenzene, rosin etc. form.
This corrugated paper box dampproof agent with modified alkyd resin by its weight percent is: soya-bean oil 20%～40%; Glycerine 20%～40%; Rosin 5.0%～15%; MALEIC ANHYDRIDE 0.2%～0.8%; Tetra hydro Phthalic anhydride 30%～50%; Phenylformic acid 5.0%～8.0%; , catalyzer 0.1%～0.3%; Dimethylbenzene 20%～40%; Rosin 30%～50% composition such as grade.
A kind of corrugated paper box dampproof agent modified alkyd resin, its preparation method is: by soya-bean oil, rosin, Tetra hydro Phthalic anhydride, MALEIC ANHYDRIDE, glycerine and dimethylbenzene join in reaction kettle of the esterification, be warming up to 150 ℃, start agitator, continue to be while stirring warming up to 170 ℃～175 ℃, constant temperature backflow 1h, continue to be warming up to 200 ℃～230 ℃, backflow esterification, treat acidity, after viscosity is qualified, in suction letdown tank, while being cooled to 160 ℃ of left and right, being blended into rosin stirs, while cooling to 80 ℃, purification filtering, after fineness is qualified, get product, standby.
Embodiment
Below in conjunction with embodiment, the invention will be further described
1, by its weight percent, accurately take soya-bean oil 25%; Glycerine 27%; Rosin 10%; MALEIC ANHYDRIDE 0.3%; Tetra hydro Phthalic anhydride 39%; Phenylformic acid 6.0%; Catalyzer 0.1%; Dimethylbenzene 20%; Rosin 30%, standby.
2, preparation method
Soya-bean oil, rosin, Tetra hydro Phthalic anhydride, MALEIC ANHYDRIDE, glycerine and dimethylbenzene are joined in reaction kettle of the esterification, be warming up to 150 ℃, start agitator, continue to be while stirring warming up to 170 ℃～175 ℃, constant temperature backflow 1h, continues to be warming up to 200 ℃～230 ℃, backflow esterification, after acidity, viscosity are qualified, in suction letdown tank, while being cooled to 160 ℃ of left and right, be blended into rosin and stir, while cooling to 80 ℃, purification filtering, after fineness is qualified, get product.
