Abstract
The invention discloses a paper softening agent and a preparation method thereof, belonging to the technical field of papermaking. The paper softening agent is prepared from the following components in parts by weight: 30-40 parts of sodium polyacrylate, 20-30 parts of starch, 20-30 parts of sodium alginate, 15-20 parts of diisocyanate, 5-15 parts of hexylene glycol, 5-10 parts of sodium stearate, 5-8 parts of urea and 3-8 parts of citric acid. The paper softening agent prepared by the preparation method provided by the invention has excellent softness and excellent mechanical strength and also has certain humidity and certain cleaning effect.
Description
Technical field
The invention belongs to pulp technology for making paper, particularly a kind of paper softener and preparation method thereof.
Background technology
Along with the continuous progress of science and technology, improving constantly of living standards of the people, people are also more and more higher to the performance requirement of stationery daily necessities, in order to meet the requirement of people to paper for daily use, there is the improvement of a lot of literature research for the flexibility of the family life such as toilet paper, napkin paper paper using, mainly by adding quaternary ammonium salt softener, particularly to more obvious with the paper effect of the raw materials such as cane syrup, reed pulp, bamboo pulp.
Use paper softener can reduce the adhesion between fiber, reduce on the one hand the frictional force between paper and skin, can cause on the other hand the decline of paper mechanical property, this class paper softener is mainly by forming the outside reverse adsorption of hydrophobic group at fiber surface, reduce the dynamic and static friction factor of fibrous matter, thereby obtain the feel of smooth, soft.
Summary of the invention
For above-mentioned demand, the object of this invention is to provide a kind of paper softener and preparation method thereof, this softener can make paper have good flexibility, mechanical strength, and has certain humidity, has certain cleaning action.
Object of the present invention can be achieved through the following technical solutions:
A kind of paper softener, made by the component that comprises following weight portion:
Sodium Polyacrylate 30-40 part,
Starch 20-30 part,
Sodium alginate 20-30 part,
Vulcabond 15-20 part,
Hexylene glycol 5-15 part,
Odium stearate 5-10 part,
Urea 5-8 part,
Citric acid 3-8 part.
Described starch is amylopectin.
The degree of branching of described amylopectin is 35%.
A preparation method for paper softener, the method comprises the following steps:
(1) Sodium Polyacrylate 30-40 part, starch 20-30 part and sodium alginate 20-30 part are added in hexylene glycol 5-15 part and odium stearate 5-10 part to ultrasonic 0.5 hour;
(2) in the product of step (1), pass into nitrogen, in condition of nitrogen gas, add vulcabond 15-20 part and urea 5-8 part, at 50-60 DEG C, stir 2-3 hour, stop reaction, slowly add citric acid 3-8 part, at 90-110 DEG C, mix, obtain paper softener.
Ultrasonic temperature in described step (1) is 50-60 DEG C.
beneficial effect:
The present invention is by adding wetting agent to reduce the friction between paper and skin, improve the flatness of fiber, increase the smooth and fine and smooth sense of paper, thereby can experience soft characteristic in the time of paper using, the present invention has added the component of multiple hydroxyl, and has added vulcabond, a part of hydroxyl can be cross-linked, thereby in increasing paper compliance and fine and smooth sense, can not reduce the mechanical strength of paper.The component of adding due to the present invention has the ability of certain moistening and clean skin, can effectively remove dirt after contacting skin.
Detailed description of the invention
Below in conjunction with embodiment, the present invention is further illustrated.
Method of testing: the paper softener that embodiment 1-3 is made joins in three parts of identical pulp materials processed with the mass ratio of 1:80 respectively, after stirring, makes finished paper at 90-120 DEG C; Contrast sample is not add the finished paper that softener is made.Paper sheet thickness is 20 grams/m.
