Abstract
The invention discloses an environmentally-friendly marine organism base flame retardation paper and a production method thereof, and belongs to the technical field of environmentally-friendly flame retardation materials. The method comprises the following steps: selecting algal chopped fibers with the average length of 3-6mm as paper pulp fibers, and mixing the alga chopped fibers with a wood pulp, adding a dispersant to the obtained mixed pulp in order to realize stability and dispersion; and carrying out papermaking on the dispersed mixed pulp by using a papermaking machine in order to make the flame retardation paper. The paper with flame retardation performance and durability is made through a simple production process with the algal chopped fibers as the paper pulp fibers without adding any flame retardant, and metal ions in the algal chopped fibers have a catalytic cracking effect, so generation of combustible gases is reduced, and the limit oxygen index of the flame retardation paper obtained through the method is greater than 30%. The environmentally-friendly marine organism base flame retardation paper has the advantages of simple process flow, environmental protection, and lasting and stable effect, and solves the problem of introduction of toxic flame retardants harmful to environment in the paper making process.
Description
Technical field
The invention belongs to environmental-protection flame-retardant technical field of material, and in particular to a kind of environment-friendly type marine organisms base is fire-retardant
Paper and preparation method thereof.
Background technology
Main component in traditionally on paper material is cellulose, hemicellulose and a small amount of lignin, and paper is fine by plant
Dimension interweaves Jing after manufacturing paper with pulp and constitutes, and the inflammability of Plant fiber directly determines the combustibility of paper product, and in traditionally on paper material
Key component be all inflammable constituent, and under normal circumstances the burning oxygen index (OI) of paper between 15%-20%, thus paper product
Using the hidden danger for being often accompanied by initiation fire.The whole world every year because of the huge economic loss that its slight susceptibility to combustion is caused, therefore,
The fire resistance of paper material has become the important performance indexes of its application.
Fire retardant papers refer to there is the paper for suppressing propagation of flame performance (i.e. with flame self-eliminating) when catching fire, and belong to extraordinary
The category of paper.The anti-flammability of paper refers in flame there is carbonization but without naked light burning, and the expansion generation to flame hinders to make
With.At present paper is fire-retardant generally by fire retardant is added come what is realized, the fire retardant of paper is usually used at present and includes metal hydrogen-oxygen
Compound, metal-oxide and halogen system, boron system and nitrogenated flame retardant etc.：
(1) metal hydroxidess, metal-oxide based flame retardant and its compound, belong to inorganic combustion inhibitor category, have
Certain flame retardant effect and suppression cigarette ability, but flame retarding efficiency is low, and addition typically could obtain good resistance in more than 50wt%
Fuel efficiency fruit, this causes the processing characteristics and physical property of paper to be remarkably decreased, and it is hydroaropic substance that in addition this based flame retardant is most,
It disturbs surface and mostly is intermolecular hydrogen bond between the fiber surface of hydroxyl and is formed, so as to limit the addition of the based flame retardant
Amount；
(2) halogenated flame retardant commonly used in papermaking mainly has organohalogen compounds, halogen Ammonia hydrochlorate and halogen macromolecule etc.,
Mostly chlorine system and bromide fire retardant.Its outstanding advantages is that, with highly effective flame-retardant effect, limited oxygen index is high, but it has the disadvantage to meet combustion
After discharge dense smoke and corrosivity noxious substance, bioxin, the toxicant such as furan may be produced during fire-retardant, make one to exhale
Difficult, asphyxia is inhaled, or even disorientation affects escape chance adversely；Simultaneously its problem of environmental pollution is serious；
(3) mainly there are phosphate, APP and phosphate ester etc. for the fire-retardant phosphorus flame retardant of paper.Phosphoric acid ester is fire-retardant
Agent is most commonly seen in paper is fire-retardant, and typical species are tricresyl phosphate.Phosphorus flame retardant mainly by dilution effect and
Blanketing effect carries out fire-retardant to paper.Not only customer service halogen containing flame-retardant combustion fumes are big for phosphorus flame retardant, discharge poisonous, corrosivity
Other defects, and customer service electrodeless fire retardant high addition, have a strong impact on the shortcoming of Material Physics mechanical performance, with high resistant
Combustion property, the advantages of low cigarette, low toxicity, non-corrosiveness gas are produced, but the phosphate flame retardant being currently mainly used is mainly little point
Sub- compound, great majority are liquid, have the shortcomings that volatility height, poor heat resistance；
(4) boron flame retardant used during paper is fire-retardant is mainly comprising nothings such as Firebrake ZB, barium metaborate, Borax, ammonium borates
Machine borate compounds.Incombustible is produced when borate compounds are heated and is coated on paper surface, completely cut off contact of the paper with air, promoted
Enter carbonization；In addition, the water of crystallization decomposes that borate compounds contain, enhance to a certain extent flame retardant effect；Mesh
Before, as fire retardant still based on inorganic borate and boric acid, organoboron flame-retardant is due to its stability difference and price for boride
High factor, limits to a certain extent it and uses；
(5) for the fire-retardant nitrogen system of paper to be fire-retardant and predominantly tripolycyanamide and its derivant, dicyandiamide salt etc., Ta Menzhu
Will be by dilution effect and blanketing effect come fire retardant papers and paper products；As CN104099810A disclose a kind of environmental protection flame retardant paper and
Its preparation method, it is that plant fiber material is carried out into size degradation to obtain slurry, and the fire-retardant of different proportion is then added in the slurry
The operations such as agent are prepared, wherein fire retardant select for melamine cyanurate, the fire retardant papers limit oxygen for preparing refers to
Number is that between 18%-23%, it belongs to nitrogenated flame retardant to the fire retardant added in the patent, although nitrogenated flame retardant is with low
It is malicious, corrosion-free, to heat and UV stable, it is cheap the advantages of, but its exclusive use when flame retardant effect it is poor.
Above-mentioned five kinds of fire retardants cut both ways, and as a whole, the fire-retardant fire retardant of current paper is inevitably deposited
In the shortcoming for affecting it to use.
The content of the invention
It is an object of the invention to provide a kind of environment-friendly type marine organisms base fire retardant papers and preparation method thereof, it is from tool
There is the Sargassum chopped strand of natural inherent flame retardant performance as paper pulp fiber, and wood pulp liquid is carried out mixed and modified, be finally reached
Fire-retardant effect, fire retardant papers its limited oxygen index prepared by the method is more than 30%.
One of task of the present invention is to provide a kind of preparation method of environmental-protection flame-retardant paper.
A kind of preparation method of environmental-protection flame-retardant paper, it is the paper pulp fiber with paper pulp fiber and wood pulp liquid as raw material
For Sargassum chopped strand, the preparation method includes：
The step of a, preparation average length are the Sargassum chopped strand of 3-6mm；
B, the step of prepare wood pulp liquid that beating degree is 30-60 ° of SR；
