Abstract
The invention provides a preparation method of acrylic acid modified rosin lead resin. According to the preparation method, the mol ratio of rosin to acrylic acid to lead oxide is 1: 0.3: 0.5. The preparation method comprises the following processing steps in sequence: heating to melt the rosin under inert gas; heating to 180 to 200 DEG C; dropping acrylic acid at controlled speed that acrylic acid is complexly dropped within 45 to 50 minutes; adding lead oxide; and heating to 250 to 260 DEG C to react for 80 to 90 minutes, thus obtaining the acrylic acid modified rosin lead resin. The acrylic acid modified rosin lead resin has the characteristics of being light in color and high in softening point; and the acrylic acid modified rosin lead resin is applicable to industrial departments such as the paint department, ink department, synthetic resin department, adhesive department, electronic department and the chemical department, and can react with phenolic aldehydes and alcohols to obtain light-color phenolic aldehyde and various rosin esters.
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 has unique chemical structure and mulitiple chiral centers by a series of resin acid compositions, and the carboxyl in the 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 products through chemical modification, is widely used in the every field in the daily life, plays very important effect in the national economic development.The value ratio raw material rosin of these deep processed products is mentioned 2-10 doubly, even decades of times, and China mainly earns foreign exchange with outlet gum resin at present.China is the country of gum resin export volume maximum, accounts for about 60% of volume of world trade, and many developed countries export go back to again China from China's imported raw material rosin back through product after a series of deep processings, and are very unfavorable to conservation of resources and the Economic development of China.China is 35% to rosin deep processing and utilization rate, and by contrast, the developed country such as American-European near 100%, exists very large gap to the deep processing and utilization rate of rosin.Therefore, carry out Abietyl modified research, develop meet the 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 lower consumption and all be of great significance.Resinous acid as the rosin main component is a kind of two chemical reactivity centers that have---the chemically reactive substance of carboxylic acid and two keys, just can introduce atom or group at quarter by these two chain carriers, thereby give rosin and have desirable character, reach the purpose of modification, thereby change the rational performance of rosin, greatly expand the Application Areas of rosin, formed miscellaneous rosin derived product, be widely used in pressure sensitive adhesive, tackiness agent industry.Make multiple film glue, decorating glue, label glue, 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 are the deficiencies such as sluggish length consuming time in prior art products preparation method.
Through Chinese publication retrieval, find 416 of relevant patents of invention, 64 of utility model patents the scheme identical with present patent application of not finding.
Summary of the invention
The object of the invention is to: for the deficiencies in the prior art, propose a kind of acrylic acid modified rosin lead tree fat preparation method.
Acrylic acid modified rosin lead tree fat preparation method of the present invention, it is characterized in that: material ratio is rosin: vinylformic acid: the mol ratio of plumbous oxide is 1:0.3:0.5; Its technique may further comprise the steps, with rosin heating and melting under rare gas element, heat up 180-200 ℃, control drips vinylformic acid with the speed that added in 45-50 minutes, then, enters ethoxyquin lead, be warming up to 250-260 ℃ of reactions 80-90 minutes, sampling is dripped on the sheet glass and is cooled off, and is the transparent terminal point that is, and cooling lets cool and namely gets product.
The present invention's beneficial effect compared with prior art: by material proportion optimization, suitable catalyzer and reaction times control, make reaction become steadily, relax, be easy to control, thereby obtain, the colory product of look shallow, it has lighter color, the softening temperature high is applied to the industrial sectors such as paint, printing ink, synthetic resins, tackiness agent, electronics, chemical industry, can be made into light resol and various rosin lipid with phenolic, alcohols reaction.
