The fruit growth bagging paper (fruit-bagged paper) prepared by the invention has the advantages of high air permeability, high dry/wet strength, good waterproof performance, good shading performance and difficult black drainage, the problem that the air permeability of the existing fruit-bagged paper is lower is solved, the paper can be widely applied to implantation cultivation of various fruit, fruit anti-pollution protection can be realized, and colour and lustre of fruit is maintained to be fresh.
Description
Technical field
The present invention relates to a kind of method of utilizing the cigarette stalk to prepare fruit growth bagging paper.
Background technology
Along with the raising of people's living standard,, its quality is also had higher requirement to the ever-increasing while of the demand of fruit.In recent years, along with the popularization of fruit bag technology, China increases day by day to the demand of fruit growth bagging paper (being fruit bag paper), and year needs fruit bag paper up to 1,000 hundred million, needs 500,000 tons of paper pulp.But present fruit bag paper ubiquity air permeability phenomenon on the low side even low excessively.
Summary of the invention
The object of the present invention is to provide a kind of method of utilizing the cigarette stalk to prepare fruit growth bagging paper; the fruit growth bagging paper of its preparation (fruit bag paper) has highly-breathable, high level cadre/wet strength, good, the good not black advantage of leakiness that reaches of light-proofness of water proofing property; solved existing fruit bag paper air permeability problem on the low side; can be widely used in the various fruit growing and cultivations; can realize the anti-pollution protection of fruit, keep fruit color and luster deliciousness.
Technical solution of the present invention is:
A kind of method of utilizing the cigarette stalk to prepare fruit growth bagging paper, it may further comprise the steps: (1) soaks the cigarette stalk; (2) tobacco curing stalk slurry; (3) slurry is joined in mixing; (4) wet end moulding; (5) dewatered drying; (6) batch; (7) cutting and rewinding.
Described step (1) is that the cigarette stalk that is chopped into the 20-25mm long size is put into hot-water soak 1.5-2 hour of 90-98 degree, leaches soak, and the cigarette stalk after the immersion is as pulping raw material.
The weight of described hot water is 5-7 times of cigarette stalk dry weight.
Cigarette stalk after described step (2) is to use high-density paste mill to soak carries out defibrination, and refining concentration is 8%-12%, and the beating degree of the paper pulp that grinds is 25～35 ° of SR, promptly makes cigarette stalk slurry.
Described step (3) is cigarette stalk slurry to be mixed with the powdered carbon that soaked cigarette stalk soak join slurry, and injects and join stock tank, adds waterproofing agent and wet strength agent again and mixes stirring, and the slurries after the stirring are stored in the machine chest.
The described powdered carbon that soaked cigarette stalk soak is soaked in powdered carbon in the cigarette stalk soak and made in 2-3 hour; Described powdered carbon and described cigarette stalk slurry slurry over dry mass percent heavily of soaking cigarette stalk soak is 5%-7%, described waterproofing agent addition is 1%-2% with joining the mass percent that cigarette stalk slurry over dry is heavy in the stock tank, and described wet strength agent is 1%-4% with joining the mass percent that cigarette stalk slurry over dry is heavy in the stock tank; Described waterproofing agent is high dispersive rosin neutral sizing agent or alkyl ketene dimer; Described wet strength agent is melamine formaldehyde resin or polyamide polyamines-epichlorohydrin resins.
Described powdered carbon is that the plant base powdered carbon is broken into 60-80 purpose powdered carbon; The quality proportioning of described powdered carbon and described cigarette stalk soak is: 10 parts of described powdered carbons, and described cigarette stalk soak is 5-8 part; Described cigarette stalk soak is that the filter liquor simmer down to solute mass fraction with described immersion cigarette stalk is the liquid of 48%-52%, and described plant base charcoal is bamboo charcoal and/or charcoal.
Described step (4) is that the slurries in the machine chest are copied the paper moulding, and it is quantitatively at 35～40gm
-2, get forming paper.
Described step (5) is with the forming paper press dewatering, 100～105 ℃ of oven dry.
Because the present invention as the paper grade (stock) raw material, can save former wood pulp consumption with cigarette stalk pulp fibres, has nicotine in the cigarette stalk simultaneously.Tobacco is three big botanical pesticide, and its main active ingredient is exactly nicotine.Nicotine can be used the good vermins-proof effect that changes separately or with other reagent, and insects such as vegetable aphid are also had stronger repellent and toxic action.It is pointed out that the nicotinoids agricultural chemicals has low toxicity, efficient, low-residual, characteristics that Environmental compatibility is good, meet the developing direction of following agricultural chemicals, is a kind of " environment friendly agricultural ".In addition, use powdered carbon to help sterilization, insect protected, can regulate the humidity in the fruit bag, the good environment that can build fruit growth promotes fruit growth.
Advantage that the present invention had and good effect: the one, have high-air-permeability, can satisfy the fruits respiratory effect, can be used for the strong fruit of respiration, as the banana bagging; The 2nd, finished paper has high doing/wet strength and excellent waterproofness, after the fruit bag made from this finished paper is various fruit baggings, can prevent because of the pollution that fruit is caused, the calcination of avoiding sunlight of spraying insecticide, and the erosion that can resist the elements; The 3rd, help sterilization, insect protected; The 4th, the finished paper smooth surface, softness, the friction that has alleviated paper bag and fruit has guaranteed the smoothness of fruit surface.The finished paper sampling Detection of method preparation of the present invention, its every index is: 1, quantitative: 40 gm
-22, do strong 65.31 Nmg
-13, wet strong retention rate 45.5 %; 4, air permeability 42.02 μ m (PaS)
-15, tear index 9.23 mNm
2G
-16, water absorbent surface 10.25gm
-27, softness, not crisp.The fruit growth bagging paper of the present invention's preparation is used for various fruit baggings and has guaranteed that fruit grows, and has avoided the infringement of various unfavorable meteorological conditions and agricultural chemicals, sick worm under nature, normal condition.
