Abstract
The invention discloses the preparation method of a kind of air permeable waterproof fruit-nourishing sleeve bag paper: first step slurrying is pulled an oar: first softwood pulp and hardwood pulp are mixed, water conservancy pulper is used to carry out pulping, refining concentration is 5～6 °, then in stock tank, add water repellent agent, sizing agent, cationic starch, wet strength agent, the molding of manufacturing paper with pulp of prepared slurry is obtained wood pulp paper, prepares waterproof height and breathe freely emulsion, emulsion is overlayed on wood pulp paper uniformly；Obtain having air permeable waterproof through drying and processing and educate fruit paper, educate really paper and carry out cutting having air permeable waterproof and make set bag paper.By softwood pulp and hardwood pulp are carried out slurrying making beating, pulping, defibrination, with slurry, screen cloth molding obtain wood pulp paper, then overlay on uniformly on wood pulp paper preparing waterproof high emulsion of breathing freely, obtain the air permeable waterproof fruit-nourishing sleeve bag paper of highly-breathable and high water proofing property, increase paper strength, the utilization rate that can make paper is greatly promoted, and is suitable for different fruit and uses.
Description
Technical field
The present invention relates to the preparation method of a kind of air permeable waterproof fruit-nourishing sleeve bag paper.
Background technology
Fruit inspecting is the new special paper grown up recent years, the benefit of its maximum is to improve the exterior quality of fruit and remain in the content of pesticide on fruit, fruit is made to taste the most crisp sweet, along with growth in the living standard, domestic increasing fruit has moved towards internationalization, simultaneously, external fancy fruit is flowed into domestic market too, under powerful competition, in the mouthfeel of fruit and profile, and fruit residual pesticide whether conformance with standard, these are determined whether the essential condition of sales volume, therefore, fruit bag is the important practice weekly notes of China's fruit industry development.
Fruit bag originates from abroad the earliest, it is the most slowly to be flowed into domestic development in nearest 2 years, its major part core technology is all limited, and owing to domestic industry investment in research and development volume is bigger, this block can be innovated by Hen little You enterprise, and be all to adopt some old technology to produce, it is ventilative and water proofing property is the most poor, particularly in south, rainfall is plentiful compares the moistest region, common set bag paper the most at most keeps the utilization rate of nearly month, have to before set bag paper take off again change new, not only increase labor intensity, and often replacing can affect the growth of fruit, do not reach expected effect.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of good permeability, has the water proofing property of height, the preparation method of the air permeable waterproof fruit-nourishing sleeve bag paper that tensile strength is high.
For solving the problems referred to above, the present invention adopts the following technical scheme that, comprise the following steps: a. first step slurrying is pulled an oar: first softwood pulp and hardwood pulp are mixed, wherein percentage by weight shared by hardwood pulp is 60～70%, the beating degree of softwood pulp is between 25～30 ° of SR, and the beating degree of hardwood pulp is between 20～31 ° of SR；B. pulping: using water conservancy pulper to carry out pulping, pulping time is 5 12min；C. defibrination: refining concentration is 5～6%；The most with slurry: in stock tank, then to add water repellent agent 1.5～2.5%, sizing agent 1.2～2%, cationic starch 2.2～2.5%, wet strength agent 0.5～3%；E. screen cloth molding: the molding of manufacturing paper with pulp of prepared slurry is obtained wood pulp paper, and paper basis weight is 25g m-2；F. prepare waterproof height to breathe freely emulsion, emulsion is overlayed on wood pulp paper uniformly；G. obtain that there is air permeable waterproof through drying and processing and educate fruit paper；H. educate fruit paper and carry out cutting having air permeable waterproof and make set bag paper.
Further, in described step c, defibrination uses high-concentration paste mill, and beating degree is 35～42 ° of SR.
Further, in described step d, described sizing agent is gum rosin, and described water repellent agent is polyamide carbamide resin, and described wet strength agent is that urea aldehyde is to fat.
Further, in described step f, described waterproof high emulsion of breathing freely is prepared by following steps: first by paraffin, silicon dioxide heating and melting, be then stirred, mixing time is 20min, add sulfate, emulsifying agent and sodium polyacrylate in solution after agitation, add hot water, water is warmed up to more than 80 degree, again it is stirred, mixing time is 10min, is placed on ventilation and lowers the temperature after stirring, obtains waterproof height and breathes freely emulsion.
Further, in described step g, the temperature of drying is 90～100 DEG C.
The invention has the beneficial effects as follows: by softwood pulp and hardwood pulp are carried out slurrying making beating, pulping, defibrination, with slurry, screen cloth molding obtain wood pulp paper, then overlay on uniformly on wood pulp paper preparing waterproof high emulsion of breathing freely, obtain the air permeable waterproof fruit-nourishing sleeve bag paper of highly-breathable and high water proofing property, increase paper strength, the utilization rate that can make paper is greatly promoted, and is suitable for different fruit and uses.
Detailed description of the invention
