Abstract
The invention discloses a preparation method of high-softening-point rosin, belonging to the technical field of deep processing of rosin. The method comprises the following steps: putting 80-100 parts by weight of turpentine, 5-8 parts by weight of sodium carboxymethyl cellulose, 5-8 parts by weight of dipropylene glycol monomethyl ether and 10-15 parts by weight of oxalic acid into a reaction kettle, uniformly mixing, and reacting for 10-30 minutes with stirring at 105-150 DEG C; and filtering the reaction product, and distilling the obtained filtrate in a distillation kettle. The sodium carboxymethyl cellulose, dipropylene glycol monomethyl ether and oxalic acid are proportionally added in the preparation process, thereby effectively enhancing the softening point of the product rosin.
Description
Technical field
The invention belongs to Colophonium deep process technology field, the preparation method of a kind of high-softening-point rosin.
Background technology
Colophonium, refers to pine resin as raw material, the non-volatile natural resin obtained by different processing modes.Pine
Perfume (or spice) is important industrial chemicals, is widely used in the industries such as soap, papermaking, paint, rubber.Although the application of Colophonium is the widest
General, but it is not high enough to there is also some very important shortcomings, i.e. softening point.
Summary of the invention
The present invention provides the preparation method of a kind of high-softening-point rosin, and the Colophonium that the method prepares has high excellent of softening point
Point.
In order to solve above-mentioned technical problem, the technical solution adopted in the present invention is:
The most by weight, by 80 parts～100 parts of Colophonium, 5 parts～8 parts of sodium carboxymethyl cellulose, 5 parts～8 parts of dipropylene glycol first
Ether, 10 parts～15 parts of oxalic acid put into mix homogeneously in reactor, and stir at 105 DEG C～150 DEG C, react 10 minutes～30 points
Clock；Then, material reaction obtained filters, and gained filtrate is put in boiler and distill.
Owing to using technique scheme, there is advantages that
The present invention passes through to add a certain proportion of sodium carboxymethyl cellulose, dipropylene glycol methyl ether and oxalic acid in its preparation process,
Thus effectively improve the softening point of product Colophonium.
Detailed description of the invention
Below in conjunction with instantiation, the invention will be further described:
The preparation method of embodiment 1--high-softening-point rosin:
First 80kg Colophonium, 8kg sodium carboxymethyl cellulose, 8kg dipropylene glycol methyl ether, 12kg oxalic acid are put in reactor and mixed all
Even, and stir at 105 DEG C, react 30 minutes；Then, material reaction obtained filters, and gained filtrate is put into
Boiler distills.
The softening point of the present embodiment product Colophonium is 145 DEG C.
The preparation method of embodiment 2--high-softening-point rosin:
First 100kg Colophonium, 5kg sodium carboxymethyl cellulose, 5kg dipropylene glycol methyl ether, 10kg oxalic acid are put in reactor and mixed
Uniformly, and stir at 150 DEG C, react 10 minutes；Then, material reaction obtained filters, and gained filtrate is put
Enter in boiler and distill.
The softening point of the present embodiment product Colophonium is 146 DEG C.
The preparation method of embodiment 3--high-softening-point rosin:
First 90kg Colophonium, 7kg sodium carboxymethyl cellulose, 7kg dipropylene glycol methyl ether, 15kg oxalic acid are put in reactor and mixed all
Even, and stir at 120 DEG C, react 20 minutes；Then, will be anti-ShouldThe material obtained filters, and gained filtrate is put into
Boiler distills.
The softening point of the present embodiment product Colophonium is 145 DEG C.
