Abstract

The invention discloses antibacterial fresh-keeping aromatic composite base paper. The antibacterial fresh-keeping aromatic composite base paper disclosed by the invention has the advantages that an antibacterial agent is made into a hybrid antibacterial sizing agent to be added into a raw material, and compared with conventional methods of spraying, gluing, coating, dipping and the like, the antibacterial property is durable, environment protection is realized, and the environment is not polluted; novel composite fiber is obtained by modifying and re-spinning brucite fiber and asbestos wool fiber, not only can the defects of large fragility and small toughness of the brucite fiber be improved, but also the strength of the asbestos wool fiber is increased, and the toughness and the strength of paper are obviously improved through mutual compounding of the brucite fiber and the asbestos wool fiber; VTMS (Vinyl Trimethoxy Silane) and other effective additives are added, and chemical bonds can be formed by Si-C bonds in the VTMS and hydroxyl in cellulose, so that special surface property is given to fiber; the antibacterial fresh-keeping aromatic composite base paper which is obtained by utilizing a preparation method disclosed by the invention is fine and smooth in texture and dark green in color, has a special fresh aromatic smell of kiwifruits, has a certain inhibiting effect on bacteria and can be used as exterior and interior packaging of snack foods and foods.

Description

A kind of anti-bacterial refreshing aroma type composite base paper and preparation method thereof

Technical field

The present invention relates to pulp technology for making paper, particularly relate to a kind of anti-bacterial refreshing aroma type composite base paper and preparation method thereof.

Background technology

Paper writes, prints, paints or the sheet-like fiber goods of packaging etc., generally by the water slurry of the string through slurrying process, in online staggered combination, preliminary hydro-extraction, more compressed, dry and form.Along with the need of development and progress people to paper of society are growing, in order to meet people to the demand paper-making industry development of paper rapidly, thus also bring a series of problem, due to the more string of needs, a large amount of trees are cut down, area of woods is reducing gradually, although take some safeguard measures, such as concede the land to forestry, but its plantation speed is far smaller than by felling speed, vegetation coverage sharply declines, thus be necessary to improve prior art, increase inorfil or other beneficiating ingredients are with substituted plant fiber, not only can save a large amount of strings also to reduction papermaking cost, conserve forests and ecological environment etc. significant, realize the target of sustainable development brought benefit to the next generation truly.

Summary of the invention

The object of the invention is exactly the defect in order to make up prior art, provides a kind of anti-bacterial refreshing aroma type composite base paper and preparation method thereof.

The present invention is achieved by the following technical solutions:

A kind of anti-bacterial refreshing aroma type composite base paper, is made up of the raw material of following weight portion: hardwood pulp 46-49, recovery paper fiber 15-17, brucite fiber 10-12, asbestos wool fiber 16-18, shitosan 3-4, olive wax 4-6, phthalic anhydride 7-9, vinyltrimethoxy silane 6-7, fresh Kiwi fruit 20-25, lilac 2-3, lemon-grass 1-2,1-butyl-3-N-Methylimidazoleacetic salt 140-170, suitable quantity of water.

The preparation method of described a kind of anti-bacterial refreshing aroma type composite base paper, comprises the following steps:

(1) by removing the fresh Kiwi fruit of seed, lilac, lemon-grass adds water and breaks into slurry, add the sodium hydrate aqueous solution boiling 5-8 hour of appropriate 1-2%, use flowing water rinsed clean, add water and grind to form the antibacterial slurry of mixing;

(2) brucite fiber, asbestos wool fiber are put into 105 DEG C dry for baking oven about 3-4 hour and ground 40-50 minute, be cooled to room temperature and add phthalic anhydride in 50-60 DEG C of stirring 2-3 hour, add 1-butyl-3-N-Methylimidazoleacetic salt and be heated to 90-95 DEG C, stir 40-60 minute, spinning;

(3) shitosan, olive wax are mixed and pulverizes, add vinyltrimethoxy silane and stir 20-30 minute, dry 2-3 hour in 60-70 DEG C;

(4) hardwood pulp, recovery paper fiber and step (1), (2) material are added in beater, add suitable quantity of water making beating, then the mixing of step (3) material stirring is added, being heated to 50-55 DEG C keeps temperature to stir 1-2 hour, finally starches mixing through copy paper, squeezing, oven dry, curling discharging.

Advantage of the present invention is: antiseptic is made the antibacterial slurry of mixing and added in raw material by the present invention, and traditional sprinkling of comparing, applying glue, coating, impregnating method antibiotic property are lasting, environment friendly and pollution-free environment; Brucite fiber, asbestos wool fibre modification again spinning are obtained novel composite fibre, has both improved the deficiency that the large wilfulness of brucite fiber fragility is little, also improved asbestos wool fibre strength, both mutual compounds significantly improve toughness and the intensity of paper; Add vinyltrimethoxy silane and other effective auxiliary agents, Si-C key wherein can form chemical bond with the hydroxyl in cellulose, thus give fiber special surface nature, the special pure and fresh aromatic odor that the composite base paper quality utilizing the present invention to obtain is fine and smooth, color is dark green, have Kiwi fruit, to bacterium, there is certain inhibitory action, can be used as the exterior and interior packing of leisure food and food.
