Abstract
The invention relates to a method for preparing paper making antibacterial agents by using oil-tea camellia shells as carriers. The method is characterized in that 10 weight parts of oil-tea camellia shells particles are added into 25 to 30 weight parts of glutaraldehyde water solution, 350 to 400 weight parts of concentrated hydrochloric acid is added in a stirring way, and the reaction lasts 4 hours at 60 to 75 DEG C; 0.5 to 5 weight parts of sliver, zinc or copper metal compound solid is added, and the materials are continuously stirred for 4 to 12 hours after the dissolution; filtering, washing slag filtering are carried out until the materials to neutral, 5 weight parts of alkali liquor or reducing agents are added into the filter slag, and the materials are stirred at 40 to 80 DEG C for reaction for 0.5 to 3 hours; after the filtering is filtered slag and washed to the neutral state, and the filter slag is dried at 40 to 80 DEG C to obtain oil-tea camellia shell base paper making antibacterial agents. The antibacterial agents have the advantages that the oil-tea camellia shells are used as preparation raw materials, the resources are wide, the price is low, and the waste discharge is reduced; the preparation process is simple, the cost is lower, and high remaining rate is realized in pulp; and the preparation conditions are mild and can be easily controlled, the process equipment is less, and the operation is easy.
Description
Technical field
The present invention relates to a kind of preparation method of antiseptic, particularly a kind of preparation method who prepares paper grade (stock) antiseptic with oil-tea camellia husks, belongs to anti-biotic material technical field.
Background technology
From SARS (2003, the whole world has 2781 routine non-iodine pneumonia cases, wherein 111 example death), " bird flu " and " Influenza A H1N1 " is (by January 2nd, 2009, in China, 31 provinces, ground report confirmed cases 120940 examples altogether) occur since, people more focus on the safety of surrounding enviroment, particularly with the live anti-microbial property of closely-related various material and goods thereof of people.Paper products be people produce and live in indispensable product, be widely used in daily life, toilet paper, face tissue, paper for kitchen, food wrapper, children's book paper using, decoration paper, health and medicinal paper, bank-note paper etc. occupy an important position in people's life
Therefore, development has the paper that itself has antibacterial functions, the microorganism of paper surface is had to the antibacterial functions of inhibit feature, can bring more safety factor for life, has important practical significance.
In slurry, the additive process antiseptic that anti-bacteria paper uses of manufacturing paper with pulp mainly forms with inorganic matter supported metal ions such as zeolite, diatomite, and the antiseptic of the immobilized metal of these inorganic matters exists the shortcomings such as retention is low, stability is not strong,
Because the large multicomponent in oil-tea camellia husks (lignin, cellulose, hemicellulose etc.) is close with paper stock, when copy paper, it is easily kept in paper, and the Tea Saponin in oil-tea camellia husks itself also has anti-microbial property in addition.
Oil tea and oil palm, olive and coconut are also called the large woody edible oil tannin plant in the world four.Oil tea is the distinctive woody oleiferous plants of China, and according to statistics, more than 347 ten thousand hectares of national existing oil tea areas, produce tea seed 56,600,000,000 kg per year, approximately 30,000,000,000 kg of oil-tea camellia husks.But a large amount of oil-tea camellia husks is taken as fuel or is used as fertilizer, caused the great wasting of resources and environmental pollution, if be prepared into the agent of papermaking antiseptic, will be a kind of important material, the benefit that can improve oil tea plantation simultaneously, has good economy and Significance for Environment.
Summary of the invention
The shortcomings such as, poor stability low for current inorganic matter supported metal ion type antiseptic retention in papermaking, a kind of product stability is good, retention is high oil-tea camellia husks paper grade (stock) antiseptic and preparation technology thereof are provided, metal is attached in the surface and micropore of oil-tea camellia husks by effects such as static, ion chelatings, dispersiveness and the stability with height, to realize efficient and lasting antibacterial effect.
To achieve these goals, the present invention has adopted following technical scheme:
By 10 parts by weight of crushed, to particle size range, the oil-tea camellia husks particle between 500～1000um joins in the glutaraldehyde water solution that 25～30 weight portions are 3% containing mass concentration, stirs and adds 350～400 weight portion concentrated hydrochloric acids, stirring reaction 4 h at 60～75 ℃; Add 0.5～5 weight portion silver, zinc or copper metallization compound solid, stir and make it dissolve rear continuation stirring 4～12 hours completely; Filter, with distilled water, wash filter residue, to filtrate, be neutral, filter residue is added in the alkali lye or reductant that 5 weight portions are 3% containing mass concentration to stirring reaction 0.5～3 h at 40～80 ℃; Filter, with distilled water, wash filter residue, to filtrate, be neutral, filter residue is dried to constant weight at 40～80 ℃, obtains oil-tea camellia husks base papermaking antiseptic.
Described metallic compound solid is the mixture of one or more than two composition in silver nitrate, copper chloride, cupric sulfate pentahydrate, zinc chloride or zinc sulfate.
Described alkali lye is a kind of or two kinds of mixtures that arbitrary proportion forms in NaOH or barium hydroxide.
Described reductant is a kind of in sodium thiosulfate or sodium borohydride or two kinds of mixtures that arbitrary proportion forms wherein.
Adsorbent of the present invention compared with prior art, has advantages of as follows:
(1) the present invention utilizes discarded object oil-tea camellia husks for raw materials, and wide material sources are cheap; Be conducive to the comprehensive utilization of oil-tea camellia husks, reduce the discharge of refuse.
(2) preparation technology of the present invention is simple, and cost is lower, in slurry, in additive process papermaking, has high retention rate.
(3) reaction condition gentleness of the present invention is easy to control, and modification procedure is simple, and process equipment is few, easy operating.
