Embodiment Construction

[0012] Now in conjunction with the present invention for further detailed description.

[0013] A kind of manufacture craft of the strong bamboo pulp paper of water absorption of the present invention, concrete steps are as follows:

[0014] a. select bamboo fiber to carry out the first cooking process;

[0015] B. adding sodium hydroxide and sodium sulfide to the black liquor after the first cooking treatment and cooking for the second time to obtain bamboo fiber slurry;

[0016] c. Add a water-absorbing agent to the bamboo fiber slurry obtained in b and mix it. The preparation steps of the water-absorbing agent are as follows: mix the mixed solution of tetraethylenepentamine and suberic acid, and after mixing for 4 to 5 hours, Add epichlorohydrin for mixing, and mix for 2 to 3 hours to get it;

[0017] d. the bamboo fiber slurry mixed in c is put into the paper machine and copied into bamboo pulp paper.

[0018] Inspired by the above-mentioned ideal embodiment according t...

Abstract

A related manufacture technology for bamboo-pulp paper with strong water adsorption property comprises the following concrete steps: a, selecting bamboo fiber and performing first boiling processing; b, adding sodium hydroxide and sodium sulfide into the black liquid subjected to the first boiling processing, and performing secondary boiling to prepare a bamboo fiber pulp; c, adding a water adsorbent into the bamboo fiber pulp obtained in the step b, and mixing; and d, putting the bamboo fiber pulp subjected to mixing in the step c into a papermaking machine, so as to make the bamboo-pulp paper. The manufacture technology for bamboo-pulp paper with strong water adsorption property employs the above design and is simple, the manufactured bamboo-pulp paper is good in water adsorption property and large in dry tensile strength and wet tensile strength.

Description

technical field [0001] The invention relates to the field of bamboo pulp paper, in particular to a manufacturing process of bamboo pulp paper with strong water absorption. Background technique [0002] Products such as toilet paper and napkins require paper sheets to have good water absorption and high wet strength so that they can maintain their integrity when subjected to external forces. However, existing additives for paper with good water absorption tend to reduce the wet strength of paper, while wet strength agents often increase the water repellency of the paper surface. At present, the ideal situation is that on the basis of meeting the requirements of dry strength, it can also have good water absorption while maintaining high wet strength. Contents of the invention [0003] The technical problem to be solved by the present invention is: in order to overcome the above-mentioned problems, a manufacturing process of bamboo pulp paper with strong water absorption is ...
