preparation example Construction

[0021] A preparation method of highly water-resistant straw backing paper, comprising the following steps:

[0022] Step 1: Mix and pulp the bleached softwood pulp and bleached hardwood pulp. After disc grinding and beating, the pulp is pumped to the pulp tank, the filler suspension is added and mixed evenly, then pumped to the pulp tank, and nanocellulose is added. , cationic starch and alum, mixed evenly and then pumped to the milling pool. After the slurry is thickened and slag removed, sizing agent is added at the outlet of a section of fine pulp, and wet strength agent, retention aid and stripping agent are continuously added online at the inlet of the pressure screen. After spraying, it enters the headbox;

[0023] Bleached coniferous wood pulp and bleached hardwood pulp are mixed according to the ratio of (4:6)~(7:3), the soaking time before beating is 1~2h, the beating concentration is 4.5~5.0%, and the beating degree is 36~39°SR ;

[0024] The filler suspension is m...

Embodiment 1

[0034]Step 1: Mix and pulp bleached softwood pulp and bleached hardwood pulp in a ratio of 4:6. The soaking time before beating is 1 hour, the beating concentration is 4.5%, and the beating degree is 39°SR. The material is pumped to the slurry tank; add talcum powder filler suspension, the suspension concentration is 8%, and the filling amount is 5%, and after mixing evenly, pump it to the slurry tank; add TEMPO oxidized microfibrillated cellulose 0.3% ( For absolute dry fiber consumption), cationic starch 0.3% (for absolute dry fiber consumption) and alum 0.2% (for absolute dry fiber consumption), after mixing evenly, pump it to the papermaking pool; Add 0.6% of anion-dispersed rosin glue (for absolute dry fiber) at the outlet of good pulp; continuously add 0.4% of polyamide epichlorohydrin (for absolute dry fiber) and 0.05% of polyacrylamide (for absolute dry fiber) at the inlet of the pressure screen fiber consumption) and cationic polymer wax emulsion 0.01% (to absolute dr...

Abstract

The invention discloses high-water-resistance sucker facial tissue and a preparation method thereof. The high-water-resistance sucker facial tissue comprises the following steps that 1, bleached needle wood pulp and hardwood pulp are mixed to be beat, filling, nano-crystalline cellulose, a sizing agent, a wet strength agent, a retention aid and others are added, and fiber pulp capable of being loaded onto a net can be prepared through residue removal and adjustment for thickening; 2, after being formed and squeezed by a fourdrinier wire paper machine, the fiber pulp is rapidly dried through alarge-diameter drying cylinder, starch and a binary surface sizing agent of polyamide polyurea resin are compounded to conduct a surface sizing process, and the high-water-resistance sucker facial tissue is prepared through drying, press polish and rolling. The prepared sucker facial tissue has good water resistance and wet strength, and can effectively prevent liquid from permeating and have goodink adaptability, and all indexes meet the safety standards of national food package materials.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a highly water-resistant straw tissue and a preparation method thereof. Background technique [0002] With the improvement of economic level and quality of life, food packaging materials are widely used in commodities, which also brings about the increasingly serious problem of white pollution. Polystyrene, polypropylene, polyvinyl chloride and other plastic products are difficult to degrade after being discarded, causing serious pollution to the environment. With the implementation of the national ban on plastics, plastic tableware is gradually eliminated by the market. Paper materials are an excellent substitute for plastics due to their recyclable and degradable advantages. In recent years, it has gradually seized the food packaging market and has a broad prospect. [0003] Plastic has always been the main material for straws due to its good plasticity and thermosetting ...
