Abstract
The invention discloses a preparation method for modified aluminium oxide rosin. The method is characterized in that the ratio among materials is that the molar ratio of rosin to acrylic acid to maleic anhydride to aluminium oxide is 1:0.3:0.3:0.5. The technology of the preparation method comprises the following steps: heating and melting rosin under inert gas, heating to the temperature of 180-200 DEG C, adding the maleic anhydride and the aluminium oxide, heating to the temperature of 250-260 DEG C, reacting for 80-90 minutes, then, dropwise adding the acrylic acid with the controlled speed that all the acrylic acid can be added within 45-50 minutes, sampling, dripping on a glass plate for cooling until the transparent color appears, cooling and placing in a cold storage, so as to obtain the final product. The preparation method has the advantages that the design is scientific and reasonable, the reaction is high in speed and moderate, the control is easy, the product has light color and excellent quality, and the softening point of the product reaches up to 185 DEG C above, and the production cost is reduced.
Description
Technical field
The invention belongs to a kind of rosin deep processing method.
Background technology
Rosin is the renewable resources of China's abundant, and annual production reaches more than 60 ten thousand tons, ranks first in the world.It is made up of a series of resinous acid, and have unique chemical structure and mulitiple chiral centers, the carboxyl in structure and phenanthrene ring frame can carry out a series of chemical modification, are a kind of natural chiral source materials.Rosin can obtain a series of deep processed product through chemical modification, is widely used in the every field in daily life, plays very important effect in the national economic development.The value ratio raw material rosin of these deep processed products mentions 2-10 doubly, and even decades of times, current China mainly earns foreign exchange to export gum resin.China is the maximum country of gum resin export volume, and account for about 60% of volume of world trade, many developed countries are from China's imported raw material rosin, and after a series of deep processing, product exports go back to again China back, to the conservation of resources of China and Economic development very unfavorable.China is 35% to rosin deep processing and utilization rate, and by contrast, the developed countries such as America and Europe close to 100%, also exist very large gap to the deep processing and utilization rate of rosin.Therefore, carry out Abietyl modified research, develop meet China market demand deep processing rosin product not only to country and the development of local economy, and to the reasonable development of China's forest resourceies and utilization and at present industrial energy saving consumption reduction be all of great significance.Resinous acid as rosin main component is that one has two chemical reactivity centers---the chemically reactive substance of carboxylic acid and double bond, atom or group at quarter just can be introduced by these two chain carriers, thus imparting rosin has desired character, reach the object of modification, thus change the rational performance of rosin, greatly expand the Application Areas of rosin, defined miscellaneous rosin derivative product, be widely used in pressure sensitive adhesive, tackiness agent industry.Manufacture multiple film glue, decorating glue, trademark adhesive, adhesive tape glue, hot melt adhesive, sanitary towel glue, non-setting adhesive, EVA hot-melt adhesive, polyamide hot, seal gum, varnish paint vehicle, bookbinding glue, pipeline glue etc.In recent decades, rosin deep processing aspect, its product category, preparation method are all without large progress; , there is the deficiencies such as sluggish length consuming time in prior art products preparation method.
Retrieve through Chinese publication, find Invention patent 527, do not find the scheme identical with present patent application.
Summary of the invention
The object of the invention is to: for the deficiencies in the prior art, propose a kind of modified aluminas rosin preparation method.
Modified aluminas rosin preparation method of the present invention, is characterized in that: material ratio is, rosin: vinylformic acid: MALEIC ANHYDRIDE: the mol ratio of aluminum oxide is 1:0.3:0.3:0.5; Its technique comprises the following steps, by rosin heating and melting under an inert gas, heat up 180-200 DEG C, add MALEIC ANHYDRIDE, aluminum oxide, be warming up to 250-260 DEG C of reactions 80-90 minutes, then, control the speed dropping vinylformic acid added with 45-50 minutes, sampling is dripped on sheet glass and is cooled, and is transparently terminal, and cooling lets cool and obtains product.
Product of the present invention has lighter color, softening temperature high, is applied to the industrial sectors such as paint, ink, synthetic resins, tackiness agent, electronics, chemical industry.
The present invention's beneficial effect compared with prior art: design science is reasonable, speed of response is fast and relax, be easy to control, product look shallow, softening temperature up to more than 198 DEG C, quality is good, the advantages such as production cost reduction.
Embodiment
Embodiment
Modified aluminas rosin preparation method of the present invention, optimized by material proportion, suitable catalyzer and reaction times control, reaction become steadily, relaxes, be easy to control, thus acquisition look shallow is, colory product, it has lighter color, softening temperature high, be applied to the industrial sectors such as paint, ink, synthetic resins, tackiness agent, electronics, chemical industry, react with phenolic, alcohols and can be made into light resol and various rosin esters.
Modified aluminas rosin preparation method of the present invention, is characterized in that: material ratio is, rosin: vinylformic acid: MALEIC ANHYDRIDE: the mol ratio of aluminum oxide is 1:0.3:0.3:0.5; Its technique comprises the following steps, by rosin heating and melting under an inert gas, heat up 180-200 DEG C, add MALEIC ANHYDRIDE, aluminum oxide, be warming up to 250-260 DEG C of reactions 80-90 minutes, then, control the speed dropping vinylformic acid added with 45-50 minutes, sampling is dripped on sheet glass and is cooled, and is transparently terminal, and cooling lets cool and obtains product.
Products obtained therefrom quality index reaches following index:
