Abstract
The invention discloses a hanging raw stock added with tea dust and tea polyphenol. The hanging raw stock is preferably prepared from 30-70% of long fiber wood pulp, 20-60% of short fiber wood pulp, 1-3% of tea dust, 1-3% of tea polyphenol, 0.5-1% of a sizing agent and 5-10% of an assistant. The manufacturing method of the hanging raw stock added with the tea dust and the tea polyphenol disclosed by the invention comprises the following steps of repulping, pulping, sizing and forming, dewatering by a long net, squeezing, drying and polishing, winding and finishing to obtain the hanging raw stock. According to the hanging raw stock added with tea dust and tea polyphenol, the tea dust and the tea polyphenol are added to the hanging raw stock, so that, on one hand, the waste tea dust can be recycled; on the other hand, environmental pollution also can be prevented; the manufactured hanging raw stock not only can kill germs of the wallpaper and the germs in the manufacturing process and also inhibit and kill indoor germs when the wallpaper is applied to indoor decoration, but also can remove formaldehyde of a timber and a room, so as to play a role in purifying air.
Description
Technical field
The present invention relates to the house decorative material technical field, relate in particular to a kind of hanging raw stock and manufacture method thereof of adding tea dust and Tea Polyphenols.
Background technology
Wallpaper is a kind of application house decorative material quite widely.Therefore the incomparable characteristics of multiple other house decorative material such as color is various because wallpaper has, pattern is abundant, luxurious style, safety and environmental protection, easy construction, price are suitable are in the developed country such as America and Europe, Southeast Asia, Japan with regionally obtain popularizing of certain degree.Wallpaper is divided into a lot of classes, as coating wallpaper, overlay film wallpaper, embossing wallpaper etc.Usually produce body paper with bleached wood pulp, then process through the processing of different operations, cover as coating, printing, embossing or surface and mould, dispatch from the factory after cutting, packing.Because have certain intensity, appearance attractive in appearance and good water repelling property, be widely used in the interior decoration in dwelling house, office, hotel etc.
At present along with the raising of living standards of the people, now more and more higher to the requirement of interior decoration and air quality aspect, but to pollute be but the main aspect that causes at present room air pollution for house decorative material and furniture.Paint, wallpaper, glued board, wood shavings filler, the materials such as interior wall coating all contain the harmful substances such as formaldehyde, benzene, above material all has suitable carcinogenic, so the ornament materials that be badly in need of a kind of environmental protection of exploitation on market, purifies the air of a room is to satisfy the people to the requirement of interior decoration and people's health.
Tea Polyphenols is the general name of Polyphenols of Tea, comprises flavanol compound, anthocyanin class, flavonoids, flavonols and phenolic acid class etc.Wherein important with flavanol compound material (catechin).Tea Polyphenols claims again tea to tan or tea tannin, is one of Main Ingredients and Appearance that forms the tealeaves color, smell and taste, is also one of Main Ingredients and Appearance that has in tealeaves health care.Studies show that, the detoxifcation of Tea Polyphenols isoreactivity material tool and radiation resistance can effectively stop radioactive substance to invade marrow, and strontium 90 and Co 60 are excreted rapidly, are described as by health and medical circle " radiation jinx ".
Research finds that Tea Polyphenols has good antibacterial action, and it can kill clostridium botulinum and spore thereof, the ectotoxic activity of anti-bacteria.The various pathogens that cause diarrhoea, respiratory tract and skin infection there is antibacterial action.Tea Polyphenols has clearly inhibitory action to staphylococcus aureus, proteus, the Pseudomonas aeruginosa that causes pyogenic infection, burn, wound, and these three kinds of bacterial strains easily produce drug resistance to medicine, and the septicemia death rate that causes thus is up to 80%.Tang Yufang, Zhang Miaoling etc., the bacteriostatic activity research of Tea Polyphenols, 2005,22(5) research finds that Tea Polyphenols has stronger bacteriostatic activity to bacterium.
Tea Polyphenols also has and well goes the formaldehyde effect, Herrick F.W., Bock L.H.Thermosetting, exterior-plywood type adhesives from barkextracts.1958,8, middle research finds that formaldehyde can on C-6 and C-8, necleophilic reaction occur with tea polyphenolic compounds.The researcher also utilizes Tea Polyphenols to carry out the Preliminary Applications test as methanal trapping agent afterwards.Encourage and build honor, Yu Qilin etc., the response characteristic research of Tea Polyphenols and formaldehyde, 2008,8(2) research finds that Tea Polyphenols is a kind of good methanal trapping agent, can well remove formaldehyde.
We study and find tea dust and Tea Polyphenols are added in hanging raw stock, can not only kill the bacterium in wallpaper itself and manufacture process, when wallpaper is applied in interior decoration, suppresses and kill indoor bacterium; And can also remove timber and indoor formaldehyde, play the effect that purifies air.
