Description
[technical field]
The invention belongs to pulp technology for making paper, and in particular to a kind of preparation method of finished product sinocalamus latiflorus toilet paper.
[background technique]
The production method of paper pulp mainly includes the productions stream such as chemical method, semichemical method, Mechanical Method and chemical mechanical pulping at present
Journey.Wherein chemical pulping is occupied an leading position among current numerous pulping process.Claim by paper pulp made from chemical method boiling
For true qualities paper pulp, true qualities paper pulp limits its application since whiteness is lower, and true qualities paper pulp will could generally give birth to after bleaching
Produce the paper kind of higher level.If the whiteness of true qualities paper pulp can be improved in pulping process, the fiber crops of following bleaching can be saved
It is tired, simplify production procedure, reduces production cost, and improve the use value of true qualities paper pulp.
Paper for daily use, particularly toilet paper are a kind of common daily consumption articles, still, in psychologically to whiteness
It needs and the demand to some physical indexs, generallys use the pulp manufacture based on bleached wood pulp.Even if being starched using herb
Toilet paper is prepared, bleached pulp is also all used.
In the production process of true qualities paper pulp, for wood raw material, carried out in pulping process using sodium hydroxide and vulcanized sodium
The sulfate process of boiling is main pulping process, and small part uses sulfite pulping, but these use sulfur-bearing chemicals
The method of boiling there are the problem of be exactly can environmental danger.For non-wood material, soda processes or burning are mainly used at present
Soda-AQ qulping, presently, there are waste liquids to be difficult to the problem of recycling for this pulping process.In addition, either sulfate process, caustic soda
Method or alkali-AQ pulping, since the lignin in raw material is condensed during the cooking process, resulting true qualities pulp brightness is all
It is lower, therefore development of the free of contamination novel high whiteness true qualities paper pulp manufacturing technique for paper industry is sought with important meaning
Justice.
Patent document " a kind of true qualities method of manufcturing paper pulp (Authorization Notice No.: CN103924470B) for improving pulp brightness "
A kind of production method of true qualities paper pulp for improving bamboo paper pulp brightness is disclosed, this method includes locating bamboo raw material SODIUM PERCARBONATE in advance
After reason, then with the mixed organic solvents of formic acid, acetic acid and acetone boiling is carried out, the paper pulp after boiling uses formic acid and hot water wash
It washs, finally prepares true qualities paper pulp, however gained bamboo paper pulp yield and whiteness are still lower.
With the continuous expansion of paper industry, constantly opening up for pulp applications is wide, originally the wood as main paper making raw material
Gradually supply falls short of demand for material, and forest is caused excessively to be cut down, and influences ecological environment, therefore, it is necessary to seek new raw material substituent.
Sinocalamus latiflorus (Dendrocalamus latiflorus Munro) is that south China cultivates most wide one of bamboo kind, is standing grain
Undergraduate course (Poaceae) Bambusoideae (Bambusoideae) Dendrocalamus (Dendrocalamus) large-scale sympodial bamboo kind, is distributed mainly on
The provinces and regions such as Fujian, Taiwan, Guangdong and Guangxi Provinces, Yunnan, Hainan, Sichuan, the Guizhou middle and south, for edible, material use, Ye Yong, water and soil conservation, greening
The multipurposes bamboo kind such as ornamental, to produce bamboo shoot or do based on pulpwood.Sinocalamus latiflorus growth is fast, the bamboo shoot phase is long, yield is high, bamboo shoot are of fine quality good, sinocalamus latiflorus
Fast growing, widely used, primary plant utilizes for many years, is that a kind of economic value is high, excellent calculation material profitable on ecology is dual-purpose
Bamboo kind, economic benefit, ecological benefits and social benefit Three benefits are significant.
Therefore be conducive to avoid result in forest and excessively cut down as wood raw material is replaced using artificial growth sinocalamus latiflorus, influence
Ecological environment.

Can by comparative example 1-4 it is found that percarbamide, amino carboxylic acid, vanadic anhydride is not added in secondary pretreatment immersion liquid B
Reduce the brightness of toilet paper, tensile index, pliability release this is because percarbamide, which will be slow, releases hydrogen peroxide
Hydrogen peroxide and lignin reaction；Amino carboxylic acid can play chelation；Vanadic anhydride plays the role of catalysis；Simultaneously by reality
The brightness of the life paper of example 3 and comparative example 1-4, tensile index, percarbamide known to pliability, amino carboxylic acid, vanadic anhydride
Addition plays synergistic effect, improves brightness, the tensile index, pliability of toilet paper.
By comparative example 5-7 it is found that alkyl phenol polyoxyethylene ether, triethanolamine, tristearin once is not added in pretreatment immersion liquid A
Acid, oleic acid, lauric acid can reduce the brightness of toilet paper, tensile index, pliability, this is because alkyl phenol polyoxyethylene ether,
Triethanolamine is wetting agent, plays good humidification；It is living that stearic acid, oleic acid, lauric acid play sinocalamus latiflorus crushed material surface
Property effect；The alkylphenol-polyethenoxy known to the brightness of example 3 and the toilet paper of comparative example 5-7, tensile index, pliability simultaneously
Ether, triethanolamine, stearic acid, oleic acid, lauric addition play synergistic effect, improve brightness, the anti-tensile of toilet paper
Index, pliability.
In addition, by the above table it is found that the brightness of toilet paper prepared by the present invention, tensile index, pliability are significantly above
The brightness of toilet paper made from the prior art, tensile index, pliability.
The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments, and it cannot be said that
Specific implementation of the invention is only limited to these instructions, and for person of an ordinary skill in the technical field, is not being departed from
Under the premise of present inventive concept, a number of simple deductions or replacements can also be made, all shall be regarded as belonging to the present invention by being submitted
Claims determine scope of patent protection.
