Description
Technical field
The invention belongs to glue production fields, and in particular to a kind of starch glue and preparation method thereof.
Background technique
With the development of express delivery cause and the raising of people's environmental consciousness, existing cardboard, carton are also widely applied, existing
Some papery manufacturing enterprises, usually using amylum adhesive as cardboard, the binder of carton, amylum adhesive is to be with starch
Natural glue made of base-material, starch are the natural polymers that green plants is generated by photosynthesis, therefore starch gluing
Agent belongs to natural plant gum, and starch adhesive is largely used in just because of the extensive of its source, price be low, easy to use, nonhazardous
The various aspects such as carton, cardboard, stamp, timber processing, bookbinding, but existing amylan bond properties is poor, uses
It is easy to degumming in the process, and it is easy to appear blisterings, false phenomena such as gluing.
Summary of the invention
For overcome the deficiencies in the prior art, the purpose of the present invention is to provide a kind of starch glues, and the starch glue is not
Toxic organic solvents are added, and stability is good, high solidity, adhesion strength is high, does not generate harm to human body and environment.
It is this method simple process, easy to operate the present invention also provides a kind of production method of starch glue, in production process
In it is pollution-free, production equipment is few, is easy to be mass produced.
Achieving the object of the present invention can be reached by adopting the following technical scheme that:
A kind of starch glue is prepared by the component of following parts by weight meter:
Preferably, the desiccant is one of precipitated calcium carbonate, kaolin.
Preferably, the water is deionized water.
A kind of preparation method of starch glue, includes the following steps:
1) prepare raw material according to the ratio, be that cornstarch adds water and tapioca adds water two parts by moisture；
2) will be after corn starch ground, addition cornstarch, which adds, to be added water and stirred, and borax is added in stirring to suspension, then
Stir 20min, obtained solution A；
3) after grinding tapioca, addition tapioca, which adds, to be added water and stirred, and sodium hydroxide, then heating water bath is added
The temperature of water-bath is transferred to 50 DEG C by 1.5h, is stirred for 15 minutes, obtained solution B；
4) after mixing solution A with solution B, desiccant is added, is stirred for 30 minutes, obtains starch glue.
Preferably, the partial size in step 1) after corn starch ground is 0.5-1 μm.
Preferably, the revolving speed stirred in step 1) is 600-1200r/min.
Preferably, the partial size in step 2) after tapioca grinding is 0.2-0.5 μm.
Preferably, the revolving speed stirred in step 2) is 60-500r/min.
Preferably, the revolving speed stirred in step 3) is 600-1200r/min.
The beneficial effects of the present invention are:
1, starch glue of the invention does not add toxic organic solvents, and stability is good, high solidity, and adhesion strength is high,
Harm is not generated to human body and environment；
2, cornstarch of the invention and tapioca mixing can not only increase the cementability of glue, but also two kinds of shallow lakes
Powder, which is used in mixed way, to be merged into each other, and non-stick, tapioca the low stability of individual cornstarch glue is compensated for；
3, borax of the invention can not only play the role of mould proof, crosslinking, toughening, can also improve water resistance and resistance to mould
Bacterium property；The addition of sodium hydroxide is in order to by starch gelatinization, it is easier to be stirred, and sodium hydroxide can make borax be transformed into inclined boron
Sour sodium keeps viscosity more preferable；The addition of desiccant is the solid content in order to improve glue, due to desiccant with strong adsorptivity and easily
The feature of dispersibility, when they are soaked for water, hydrone is spread in its structure cell outer layer first, and is gradually spread to centre, by
In the addition of hydrone, make mutually to impact and squeeze between its particle, until particle is kept completely separate, the inorganic filler after dispersion has
Huge specific surface area is in colloidal state, has stronger adsorptivity, positively charged electrolyte can be adsorbed, with band in water
The paper fiber of negative electrical charge forms bridging effect, after mixing with starch, can often form hydrophobic reticular structure, brushes on product i.e.
A tunic is formed, so that moisture be prevented to permeate to interiors of products, rate of drying and initial bonding strength is improved, makes the caking property of glue more
By force, it is not easy to come unglued；
4, in the production technology of starch glue of the invention, the step of cornstarch, tapioca are ground respectively be for
The partial size both reduced, makes cornstarch that suspension be more readily formed in agitation phases, is tapioca in heating water bath
Stage is prevented from caking；Heating water bath not only can influence the activity of tapioca to avoid because the temperature of heating is excessively high, but also
Tapioca integrally heats up simultaneously when water-bath, avoids because unevenly causing for heating is hardened.
