Abstract

The invention discloses stellera chamaejasme flower rhizome mothproof composite base paper. Antibacterial agents prepared into a mixed antibacterial slurry, the mixed antibacterial slurry is added in raw materials, and a lasting antibacterial property, environmental protection and no pollution to the environment are achieved when the composite raw paper is compared with paper prepared through traditional methods of spraying, gluing, coating, dipping and the like. Wheat straw fibers and steel fibers are modified, spinning is carried out again, novel composite fibers are prepared, the defects of large brittleness and low toughness of the steel fibers are overcome, the wheat straw fiber intensity is raised, and the toughness and the intensity of paper are raised obviously through mutual combination. Triethoxysilane and other effective auxiliary agents are added, Si-C bonds in triethoxysilane and hydroxyls in cellulose can form chemical bonds, and therefore special surface properties are given to the fiber. The prepared composite base material has excellent physical properties and good printing performances, especially, stellera chamaejasme flower roots are employed as an antibacterial additive, the antibacterial and mothproof performances can last long.

Description

A kind of root of langdu flower rhizome Anti-moth-eating 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 root of langdu flower rhizome Anti-moth-eating 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 root of langdu flower rhizome Anti-moth-eating composite base paper and preparation method thereof.

The present invention is achieved by the following technical solutions:

A kind of root of langdu flower rhizome Anti-moth-eating composite base paper, is made up of the raw material of following weight portion: poplar bleached pulp 45-50, wheat straw fiber 25-28, steel fibre 5-8, foresite 2-4, nano titanium oxide 1-2, root of langdu flower root 4-6, the Root Bark of the Ailanthus Altissima SWINGLE 2-3, konjak starch 1.2-2.1, maleic anhydride 3-4, tetraethoxysilane 6-8, beeswax 2-3, water-soluble lanolin 15-18, potassium sorbate 0.4-0.6,1-butyl-3-N-Methylimidazoleacetic salt 120-150, suitable quantity of water.

The preparation method of described a kind of root of langdu flower rhizome Anti-moth-eating composite base paper, comprises the following steps:

(1), after root of langdu flower root, the Root Bark of the Ailanthus Altissima SWINGLE being cleaned up, little fiery fried dry is pulverized, and adds the sodium hydrate aqueous solution boiling 5-8 hour of appropriate 1-2%, uses flowing water rinsed clean, adds water and grinds to form the antibacterial slurry of mixing;

(2) wheat straw fiber, steel fibre 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 water-soluble lanolin, maleic anhydride in 50-60 DEG C of stirring 6-9 hour, spraying dry, add 1-butyl-3-N-Methylimidazoleacetic salt and be heated to 90-95 DEG C, stir 40-60 minute, spinning;

(3) foresite, beeswax are mixed and pulverize, add nano titanium oxide, tetraethoxysilane stirs 20-30 minute, dry 2-3 hour in 60-70 DEG C;

(4) poplar bleached pulp and step (1), (2) material are added in beater, add suitable quantity of water making beating, then step (3) material is added and other residual componentss stir and evenly mix, 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; Wheat straw fiber, steel fibre modification again spinning are obtained novel composite fibre, and both improved the deficiency that the large wilfulness of fragility of steel fibre is little, also improved wheat straw fiber intensity, both mutual compounds significantly improve toughness and the intensity of paper; Add tetraethoxysilane and other effective auxiliary agents, Si-C key in tetraethoxysilane can form chemical bond with the hydroxyl in cellulose, thus give paper fiber special surface nature, the composite base paper excellent physical properties utilizing the present invention to obtain, printing performance is good, particularly with the root of langdu flower root for antibacterial additives antibacterial Anti-moth-eating performance more lasting.
