Abstract

The invention discloses a preparation method for a gadolinium trioxide rosin glyceride resin. The preparation method comprises the following steps: heating 100 parts by weight of rosin to 150-160 DEG C for smelting, adding 20-22 parts by weight of gadolinium trioxide and 5-15 parts by weight of maleic anhydride, reacting for 1.5-2 hours at the temperature of 180-200 DEG C, adding 10-15 parts by weight bisphenol A, stirring 0.3-0.5 hour, cooling to 90-100 DEG C, adding 12-30 parts by weight of formaldehyde and 1-3 parts by weigh of the accelerant hexamethylenetetramine, stirring for 2-2.5 hours at the temperature of 90-100 DEG C, adding at least 80 parts by weight of glycerol, increasing the temperature to 180-200 DEG C, stirring for reacting for 2-2.5 hours, heating to 270-280 DEG C, and conducting vacuum-pumping for 1 hour, so that the gadolinium trioxide rosin glyceride resin is obtained. The preparation method for the gadolinium trioxide rosin glyceride resin has the advantages that the design is scientific and reasonable, the reaction speed is high, moderate and easy to control, the product color is light, the softening point is as high as 185 DEG C above, the quality is good, and the manufacturing cost is reduced.

Description

Gadolinium sesquioxide ester gum process for preparing resins

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 gadolinium sesquioxide ester gum process for preparing resins.

Gadolinium sesquioxide ester gum process for preparing resins of the present invention, is characterized in that: by weight, and rosin 100 parts heats 150-160 DEG C of meltings, adds gadolinium sesquioxide 20-22 parts; MALEIC ANHYDRIDE 5-15 parts, carries out reaction 1.5-2 hours at 180-200 DEG C; Add dihydroxyphenyl propane, 10-15 parts, stir 0.3-0.5 hour, be cooled to 90-100 DEG C, add 12-30 parts, formaldehyde, promotor hexamethylenetetramine 1-3 parts, 90-100 DEG C are stirred 2-2.5 hours, add glycerine and be no less than 80 parts, heat up 180-200 DEG C, stirring reaction 2-2.5 hours, is warming up to 270-280 DEG C and vacuumizes 1 hour; Both product was obtained.

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 185 DEG C, quality is good, the advantages such as production cost reduction.

Embodiment

Of the present inventionly raw materials usedly buy acquisition.

Products obtained therefrom quality index reaches following index:
