Abstract
The invention discloses a solid binder, which comprises the following raw materials: pullulan, glycerin, methylcellulose, sodium benzoate and water, wherein the pullulan has good water solubility, and achieves an adhesion effect in short time, so that the solid binder has a large adhesion force, and can play a role in paper and the like in short time and then form a firm, soft and elastic adhesion envelope; and because the molecular structure of the pullulan is serrated, the pullulan and fiber are bonded firmly, and therefore, the binder has a larger adhesion force when the binder is wet. The main raw material pullulan of the solid binder disclosed by the invention is non-toxic and harmless to human body, and does not produce high-temperature and harmful gases in the process of burning, and therefore, the binder is environmentally friendly; and a binder coating for adhering is not cracked after being dried, not affected by the atmospheric humidity, and not naturally stripped after being preserved at low humidity and high humidity. The preparation method of the binder disclosed by the invention is simple, and strong in operability.
Description
Technical field
The present invention relates to the technical field of tackiness agent, is a kind of green non-poisonous solid binder and preparation method thereof specifically.
Background technology
In prior art, solid binder in paper product, office appliance and stationery, normal using gelatin, modified starch, gum arabic, polyvinyl alcohol etc. as raw material, above-mentioned substance water-soluble little, dissolution time is long, and playing after bonding that clinging power required time is long and the clinging power hold-time is short, tackiness agent easily goes mouldy when humidity is high, then easily dry and cracked thus cause adhesion naturally to be peeled off time dry.
And the tackiness agent used at present is generally containing benzene, substituted benzene or formaldehyde, these objectionable impuritiess all can affect HUMAN HEALTH.For protection of the environment, safeguard that people's is healthy, the tackiness agent of research asepsis environment-protecting is the inexorable trend of development.
Pulullan polysaccharide (Pullulan) is a kind of exocellular polysaccharide that Aureobasidium pullulans (Aureobasidium Pullulans) fermentation produces, also known as pullulan, Pul or pulullan, it is the polymer natural polysaccharide that a kind of colorless and odorless is nontoxic.
Summary 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 technical scheme that the present invention takes for the technical problem existed in solution known technology is:
Solid binder of the present invention, comprises each component of following weight percent:
The present invention can also adopt following technical measures:
The molecular weight of described pulullan polysaccharide is 150-250kDa.
The preparation method of solid binder of the present invention, joins the pulullan polysaccharide of said ratio, glycerine, methylcellulose gum and Sodium Benzoate in the water of 30-50 DEG C, mixture is heated to 90 DEG C, and insulated and stirred is to all dissolving; Above-mentioned solution is at room temperature cooled three minutes, and solution flowing stops and starting solidification, obtains solid binder.
The above-mentioned solution of 90 DEG C is injected in the cylindrical container that specification is 14mm × 50mm.
The advantage that the present invention has and positively effect are:
In solid binder of the present invention and preparation method thereof, raw material is adopted to comprise pulullan polysaccharide, glycerine, methylcellulose gum, Sodium Benzoate and water, pulullan polysaccharide has water-soluble preferably, play sticking action not need for a long time, clinging power is large, can play a role in the short period of time such as paper, formed firmly, soft resilient adhesion tunicle, due to the molecular structure indentation of pulullan polysaccharide, be combined firmly with fiber, time moist, clinging power is larger.Main raw material pulullan polysaccharide of the present invention is harmless to human non-toxic, does not produce high temperature and obnoxious flavour, environmental protection during burning; Pulullan polysaccharide has certain resistance, even if tackiness agent in wet condition also can not mildew to the general microorganism microbial growth that particularly amylase produces; Adhesive coating in adhesion be dry after can not occur dry and cracked, and not by the impact of atmospheric moisture, low humidity and high humidity are preserved and all can not naturally be peeled off.Glycerine in main raw material contributes to the flexibility of promoting adhesion face; Methylcellulose gum is as the thickening material of tackiness agent.The preparation method of tackiness agent of the present invention is simple, workable.
