Abstract
A kind of solid binder, raw material includes pulullan polysaccharide, glycerine, methylcellulose, sodium benzoate and water, pulullan polysaccharide has preferable water-soluble, playing sticking action need not for a long time, and adhesion strength is big, to that can be played a role in the short time such as paper, form firm, flexibly resilient adhesion envelope, because the molecular structure of pulullan polysaccharide is serrated, it is firmly combined with fiber, adhesion strength is bigger when moist.The primary raw material pulullan polysaccharide of the present invention is nontoxic to human body, and high temperature and pernicious gas, environmental protection are not produced during burning；Adhesive coating in adhesion will not occur dry and cracked after the drying, and not influenceed by atmospheric humidity, and low humidity and high humility are preserved all without peeling off naturally.The preparation method of the adhesive of the present invention is simple, workable.
Description
Technical field
The present invention relates to the technical field of adhesive, specifically a kind of green non-poisonous solid binder and its preparation side
Method.
Background technology
In the prior art, the solid binder in paper products, office appliance and stationery, often with animal glue, denaturation
Starch, Arabic gum, polyvinyl alcohol etc. as raw material, above-mentioned substance it is water-soluble small, dissolution time is long, and is played after bonding viscous
The long and adhesion strength retention time is short the time required to putting forth effort, and adhesive easily goes mouldy when humidity is high, then easily dry when drying
Split to cause adhesion to be peeled off naturally.
And the adhesive used at present generally contains benzene, substituted benzene or formaldehyde, these harmful substances can all influence people
Body health.For environmental protection, safeguard that people's is healthy, the adhesive of research asepsis environment-protecting is the inexorable trend of development.
Pulullan polysaccharide (Pullulan) is one that Aureobasidium pullulans (Aureobasidium Pullulans) fermentation is produced
Kind exocellular polysaccharide, also known as pullulan, Pul or pulullan, are that a kind of nontoxic macromolecule of colorless and odorless is naturally more
Sugar.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of green non-poisonous solid binder and preparation method thereof.
The present invention is adopted the technical scheme that to solve technical problem present in known technology：
The solid binder of the present invention, includes each component of following percentage by weight：
The present invention can also use following technical measures：
The molecular weight of described pulullan polysaccharide is 150-250kDa.
The present invention solid binder preparation method, by the pulullan polysaccharide of said ratio, glycerine, methylcellulose and
Sodium benzoate is added in 30-50 DEG C of water, heats the mixture to 90 DEG C, and insulated and stirred is to whole dissolvings；Will be above-mentioned molten
Liquid is cooled down three minutes at room temperature, and solution flowing stops and starts solidification, produces solid binder.
90 DEG C of above-mentioned solution is injected into the cylindrical container that specification is 14mm × 50mm.
The present invention has the advantages and positive effects of：
In solid binder of the present invention and preparation method thereof, pulullan polysaccharide, glycerine, methyl are included using raw material fine
Dimension element, sodium benzoate and water, pulullan polysaccharide have preferable water solubility, and playing sticking action need not for a long time, adhesion
Power is big, to that can be played a role in the short time such as paper, firm, flexibly resilient adhesion envelope is formed, because Propiram is more
The molecular structure of sugar is serrated, and is firmly combined with fiber, adhesion strength is bigger when moist.The primary raw material Propiram of the present invention is more
Sugar is nontoxic to human body, and high temperature and pernicious gas, environmental protection are not produced during burning；Pulullan polysaccharide is to general microorganism
The growth of the particularly microorganism that amylase is produced has certain resistance, and adhesive is even if in wet condition also will not mildew；
Adhesive coating in adhesion be it is dry after will not occur dry and cracked, and do not influenceed by atmospheric humidity, low humidity and high humility are protected
Deposit all without stripping naturally.Glycerine in primary raw material helps to promote the flexibility of adhesion film surface；Methylcellulose is as viscous
The thickener of mixture.The preparation method of the adhesive of the present invention is simple, workable.
