Abstract
The invention relates to the technical field of the auxiliary drying of a corrugated paper adhesive, and particularly provides a natural quebracho tannin drying agent and a preparation method thereof. The natural tannin is used as a preparing material and is reacted with sodium sulfite to generate a tannin extract product. The natural quebracho tannin drying agent added in the corrugated paper adhesive can effectively improve the drying performance and the adhesion performance of a starch adhesive; and the process is not necessarily adjusted when the natural quebracho tannin drying agent is prepared and used, so the preparation method is conveniently used.
Description
Technical field
The present invention relates to the drying aid technical field of fluting board tackiness agent, specifically provide the wooden tannin siccative of a kind of natural heavily fortified point.
Background technology
Tackiness agent is one of main subsidiary material in the corrugated cardboard course of processing, also is the important factor that influences the corrugated cardboard quality.The tackiness agent kind is a lot, and Starch Adhesive accounts for sizable ratio because advantage that it had has generally been adopted by domestic and international manufacturer at present in paper packing material and paper container bonding.
But Starch Adhesive seasoning speed is slow, also is not equipped with good drying plant on the domestic production line.Therefore the rate of drying that improves Starch Adhesive has great importance for the quality that improves cardboard.At present the approach of the dried modification of Starch Adhesive mainly contains two kinds: filled urge doing and adding synthetic resins urge dried.These two kinds of methods all are the pure chemistry sinteticses, do not possess the feature of environmental protection.
Summary of the invention
The present invention is exactly to above problem, and wooden tannin siccative of a kind of natural heavily fortified point and preparation method thereof is provided, and it adopts the pure natural tannin as raw making materials, produces the siccative of environment-friendly high-efficiency.
The technical scheme that the present invention adopted is following: 1, the wooden tannin siccative of a kind of natural heavily fortified point, its structural molecule formula does
The preparation method of the wooden tannin siccative of a kind of natural heavily fortified point may further comprise the steps:
A, be that the S-WAT of 89% tannin and 11% adds in the agitator tank and stirs with mass ratio, the temperature inside the box is controlled at 100-120 ℃, churning time 30 minutes;
B, above-mentioned substance added carry out chemical reaction in the reaction kettle, temperature control 110-120 ℃, reacted 10 hours;
C, spraying drying.
The wooden tannin siccative of natural heavily fortified point of the present invention, its drying mechanism is: be interweaved with the corn starch adhesive agent molecule, form bigger network, increased cohesive strength, benzene-acrylic emulsion gene of surging helps the volatilization of moisture, has accelerated rate of drying.
In the fluting board tackiness agent, add the wooden tannin siccative of natural heavily fortified point of the present invention, can effectively improve the drying property and the bond properties of Starch Adhesive, and technology needn't be adjusted when preparation and use, easy to use.
Embodiment
Below in conjunction with specific embodiment the wooden tannin siccative of a kind of natural heavily fortified point of the present invention is done further to describe.
Embodiment 1:
The wooden tannin siccative of a kind of natural heavily fortified point of the present invention is based on a kind of natural tannin extract of improved.
Its structure can have the unit molecule structure, dimer structure, trimer structure.
Below provide a kind of unit molecule structural molecule formula:
Embodiment 2:
Present embodiment provides an other unit molecule structural molecule formula:
Embodiment 3:
The preparation method of the wooden tannin siccative of a kind of natural heavily fortified point may further comprise the steps:
A, be that the S-WAT of 89% tannin and 11% adds in the agitator tank and stirs with mass ratio, the temperature inside the box is controlled at 100-120 ℃, churning time 30 minutes;
B, above-mentioned substance added carry out chemical reaction in the SS304 reaction kettle, temperature control 110-120 ℃, reacted 10 hours;
C, spraying drying.
Above-described embodiment, the present invention embodiment a kind of more preferably just, common variation that those skilled in the art carries out in technical scheme scope of the present invention and replacement all should be included in protection scope of the present invention.
Claims (2)
1. wooden tannin siccative of natural heavily fortified point, its structural molecule formula does
2. the preparation method of the wooden tannin siccative of natural heavily fortified point may further comprise the steps:
