As a preferable technical solution, the plant fiber is at least one selected from plant straw fiber, wood fiber, bamboo fiber, hemp fiber and cotton fiber.
As a preferable technical scheme, the fiber is a mixture of straw fiber and fibrilia, and the mass ratio of the straw fiber to the fibrilia is (3-5): 1.
the straw is a general term of the stem and leaf parts of mature crops. Generally refers to the remainder of wheat, rice, corn, potatoes, oilseed rape, cotton, sugar cane and other crops after harvesting the seeds. More than half of the products of crop photosynthesis exist in the straws, and the straws are also a coarse feed and are characterized by high content of coarse fibers and containing lignin, and the straw fibers are the fibers of the straws. The straw fiber has better hydrophobic property and ageing resistance.
As a preferred technical scheme, the straw fiber is wheat straw fiber.
As a preferable embodiment, the mineral fiber is at least one selected from the group consisting of an aluminum silicate fiber, a glass fiber, a gypsum fiber, and a carbon fiber.
Mineral fibers are increasingly used in the paper industry. Its excellent properties can make paper possess the functions which plant fibre does not have.
As a preferred technical solution, the mineral fiber is gypsum fiber.
The gypsum fiber is a mineral fiber with excellent performance and low price. The gypsum microfiber can be used as a reinforcing agent in paper making to improve the strength of paper, reduce the consumption of wood, protect the environment, reduce the wastewater discharge in a paper mill and reduce pollution, and the gypsum fiber has better dispersibility and can not agglomerate in paper pulp.
In a preferred embodiment, the antibacterial agent is a guanidine polymer, and the guanidine polymer is polyguanidine salt and/or polybiguanide salt.
As a preferred technical solution, the polyguanidine salt is polyhexamethylene guanidine hydrochloride.
The polyhexamethylene guanidine hydrochloride has the advantages of wide sterilization range, low effective concentration, high action speed, stable property, long-term bacteriostasis, no side effect, no corrosion, no color, no smell, no toxicity, no combustion, no explosion and safe use. The polyhexamethylene guanidine hydrochloride is a polyguanidine high-molecular polymer, the polarity of amino in the polyhexamethylene guanidine hydrochloride is strong, and the amino can interact with hydroxyl on fibers, so that the polyhexamethylene guanidine hydrochloride is adsorbed on the fibers to form a durable antibacterial effect, and ammonia in the polyhexamethylene guanidine hydrochloride is a secondary amino, so that the polyhexamethylene guanidine hydrochloride is high in steric hindrance and not easy to oxidize, and the phenomenon of yellowing of paper is avoided. However, polyhexamethylene guanidine hydrochloride has poor hydrophobicity and is easy to absorb moisture, and the hydrophilic group part of the polyhexamethylene guanidine hydrochloride has strong electropositivity, adsorbs various bacteria and viruses which are usually electronegative, enters a cell membrane, inhibits the synthesis of intramembrane liposome, causes the apoptosis of thalli and achieves the optimal sterilization effect.
As a preferable technical scheme, the oxygen bleaching agent is hydrogen peroxide.
In a preferred embodiment, the degrading enzyme is at least one selected from the group consisting of xylanase, hemicellulase, a lignin degrading enzyme, cellulase and β -glucanase.
Xylan is a heterogeneous polysaccharide present in plant cell walls, accounting for about 15% to 35% of the dry weight of plant cells, and is the main component of plant hemicellulose. Most xylans are structurally complex, highly branched heterogeneous polysaccharides containing many different substituents. Biodegradation of xylan also therefore requires a complex enzyme system to degrade xylan through the synergistic interaction of the various components therein. Thus, xylanases are a group of enzymes, being xylanase systems, not one enzyme. The xylanase system is an enzyme system for degrading xylan, comprises beta-1, 4-endoxylanase, beta-xylosidase, alpha-L-arabinosidase, alpha-D-glucuronidase, acetyl xylanase and phenolic acid esterase, and can degrade xylan hemicellulose which exists in the nature in a large amount. In the xylanase system, beta-1, 4-endoxylanase is the most critical hydrolase, which hydrolyzes xylan into xylooligosaccharides such as small oligosaccharides and xylobiose, and small amounts of xylose and arabinose by hydrolyzing the beta-1, 4-glycosidic bond of xylan molecule. Beta-xylosidase catalyzes the release of xylose residues by hydrolyzing the terminal end of xylo-oligosaccharides. In addition, side chain hydrolases such as alpha-L-arabinofuranosidase, alpha-glucuronidase, acetylxylan esterase, and phenolic acid esterase capable of degrading the ester bond formed by arabinose side chain residue and phenolic acid in xylan are involved in the complete degradation of xylan, and they act on the glycosidic bond between xylose and side chain substituent, in cooperation with the action of backbone hydrolase, to convert xylan into its constituent monosaccharides.
In a preferred embodiment, the binder is a mixture of a cellulose derivative containing methyl groups and starches, and the mass ratio of the cellulose derivative containing methyl groups to the starches is: 1: (3-5).
In a preferred embodiment, the methyl group-containing cellulose derivative is at least one selected from the group consisting of methylcellulose, hydroxyethylmethylcellulose, and methylhydroxypropylcellulose.
In a preferred embodiment, the methyl group-containing cellulose derivative is methyl cellulose.
Methylcellulose is a nonionic cellulose ether made by the introduction of methyl groups into cellulose by etherification. The important functions of methylcellulose are thickening, surface activity, film forming and thermal gel forming. The methylcellulose solutions are stable over a wide range of pH (3.0-11.0) and have unique thermal gelling properties.
As a preferable technical scheme, the waterproof agent is polysiloxane derivative containing methyl.
In a preferred embodiment, the methyl group-containing polysiloxane derivative is at least one selected from polydimethylsiloxane, cyclomethicone, polymethylphenylsiloxane and polymethylhydrosiloxane.
The polysiloxane derivative containing methyl has better hydrophobicity, can form a better waterproof film on the surface of the fiber, and obviously improves the hydrophobic performance of the carton material. However, when the content of the methyl group-containing polysiloxane derivative in the carton material is high, the antibacterial property of polyhexamethylene guanidine hydrochloride is affected. The methyl-containing polysiloxane derivative can improve the compatibility among all components, reduce the friction among all components, improve the smoothness of the carton material, reduce the roughness of the carton material and further improve the mechanical property of the carton material.
The second aspect of the invention provides a preparation method of a tea leaf residue paper box material, which at least comprises the following steps:
(1) crushing plant fiber and tea leaves to 0.1-1.5mm, and adding mineral fiber, degrading enzyme and water, wherein the weight ratio of the tea leaves to the water is 2: 5, standing for 8-12h at 50-70 ℃ to obtain a mixture A;
