Abstract
The invention discloses a kind of high intensity green and environmental protection paper and preparation method and application.The preparation method of described high intensity green and environmental protection paper is：To bamboo pulp raw material pulping, it is 30~50 ° of SR bamboo pulps to obtain beating degree；Then bamboo pulp or PLA fibers are pre-processed in cationic guar solution；Pretreated bamboo pulp and undressed PLA fibers, or undressed bamboo pulp and pretreated PLA fibers are pressed 7:3 absolute dry mass ratio is manufactured paper with pulp, you can obtains high intensity green and environmental protection paper.In the present invention, the pretreatment of cationic guar solution improves the fibre strength of bamboo fibre in itself, the chemical polarity of PLA fiber surfaces and interfibrous interface compatibility, the physical property of paper is significantly improved.What the present invention used is all green material, and obtained paper has higher intensity, can be applied to the various fields such as daily life paper, food wrapper well.
Description
Technical field
The invention belongs to technical field of preparation of specialty paper, and in particular to a kind of high intensity green and environmental protection paper and preparation method thereof
With application.
Background technology
PLA (PLA) fiber is a kind of conventional degradation material, it have good biocompatibility, glossiness, thoroughly
Characteristic, its applications such as bright property and heat endurance are more and more extensive.It is if directly fine using PLA using traditional papermaking process
Dimension production high-strength material, has larger cost advantage.But due to can not be formed between PLA fibers as string
Hydrogenbond, adhesion can not meet paper making requirement between PLA fibers, so being only not all right with PLA fiber copy papers.Plant
Fiber is the most abundant renewable environment-friendly materials of nature and cheap, also possesses very excellent biological degradability.If choosing
The bamboo fibre for selecting superior performance mixes with PLA fibers, can significantly improve the intensity of paper.But because PLA fiber surfaces are smooth, and
It is hydrophobic high molecular polymer, have impact on the biocompatibility of it and hydrophily bamboo fibre.Therefore, how to make PLA fibers with
Bamboo fibre preferably combines, it appears special important.
The content of the invention
To solve the shortcomings that prior art and weak point, primary and foremost purpose of the invention is to provide a kind of high intensity green
The preparation method of environment protecting paper, improve the interface binding power between PLA fibers and bamboo fibre, prepared by enhancing PLA fibers and bamboo fibre
The intensity of paper.
Another object of the present invention is to provide high intensity green and environmental protection paper made from above-mentioned preparation method.
It is still another object of the present invention to provide the application of above-mentioned high intensity green and environmental protection paper
For achieving the above object, the present invention adopts the following technical scheme that：
A kind of preparation method of high intensity green and environmental protection paper, comprises the following steps：
(1) it is beaten to starching the dense bamboo pulp raw material for being 10%, obtains bamboo pulp of the beating degree for 30~50 ° of SR；
(2) bamboo pulp in step (1) is added in cationic guar solution, under the conditions of 25~35 DEG C, insulation 20~
30min, bamboo pulp is taken out, pretreated bamboo pulp is obtained after washing；
(3) PLA fibers and pretreated bamboo pulp are pressed 3:7 absolute dry mass ratio is manufactured paper with pulp, you can obtains high intensity
Green and environmental protection paper.
Preferably, the concentration of step (2) described cationic guar solution is 0.5wt%~1.5wt%, the over dry of bamboo pulp
Quality is 6wt%~10wt% of cationic guar solution.
Preferably, according to 80g/m in step (3)2~120g/m2Quantify and manufactured paper with pulp.
A kind of preparation method of high intensity green and environmental protection paper, comprises the following steps：
(a) it is beaten to starching the dense bamboo pulp raw material for being 10%, obtains bamboo pulp of the beating degree for 30~50 ° of SR；
(b) PLA fibers are added in cationic guar solution, under the conditions of 25~35 DEG C, is incubated 20~30min, takes
Go out PLA fibers, pretreated PLA fibers are obtained after washing；
(c) by the bamboo pulp obtained in step (a) and pretreated PLA fibers by 7:3 absolute dry mass ratio is manufactured paper with pulp,
It can obtain high intensity green and environmental protection paper.
Preferably, the concentration of step (b) cationic guar solution is 0.5wt%~1.5wt%, PLA fibers
Absolute dry mass is 6wt%~10wt% of cationic guar solution.
Preferably, according to 80g/m in step (c)2~120g/m2Quantify and manufactured paper with pulp.
A kind of high intensity green and environmental protection paper, it can be obtained by the preparation method of above-mentioned high intensity green and environmental protection paper.
Application of the above-mentioned high intensity green and environmental protection paper in paper for daily use and wrapping paper field.
Compared with prior art, the present invention has advantages below and beneficial effect：
The present invention uses guar hydroxypropyltrimonium ammonium chloride (cation guar gum) as the pre- of bamboo fibre and PLA fibers
Solvent is handled, it has the advantages of very big in security, stability, film forming, the feature of environmental protection etc..
Guar xanthan molecule contains substantial amounts of hydroxyl in itself, meanwhile, there is certain cohesive action, fiber surface can be increased
Hydroxyl value, assign PLA Hydrophilic Fiber energy, be so advantageous to the combination between PLA fibers and bamboo fibre；And bamboo fibre surface
Containing great amount of hydroxy group, what guar gum can be suitably reduces the chemical polarity on bamboo fibre surface, and it is fine with PLA to be equally beneficial for bamboo fibre
The interface cohesion of dimension.But if guar gum is directly added in fiber solution, the process of discongesting can produce substantial amounts of foam,
Fiber skewness is caused during sheet formation；If add guar gum after fiber is discongested, it is difficult to make fiber and Guar
Glue efficiently combines, and guar gum also can waste material with a part is lost in into gauze.
And the present invention pre-processes bamboo fibre, PLA fibers by guar gum, above mentioned problem was both avoided, plant can be improved again
Binding ability between fibres and synthetic fibers, the intensity of composite paper is significantly improved, solved between two kinds of fibers because of material
Hydrophilic, hydrophilic polar it is different and caused by the problem of can not combining.Meanwhile PLA fibers, bamboo fibre and cation guar gum are
The green material of fully biodegradable under field conditions (factors), paper prepared therefrom not only meet people to the high thing of paper
The requirement of rationality energy, also comply with requirement of the country to Product Green sustainable development.
