Description
Technical field
The present invention relates to paper application techniques field, more specifically a kind of high-strength cow paperboard top sizing enhancing
Agent and preparation method.
Background technology
Kraft inner paper frequently encounters the property held in actual use not enough causes carton surface impression to burst, flatness
Cause net-point printing unreal with water-resistance deficiency, the problems such as pattern is not true to nature, this is accomplished by kraft inner paper top sizing, surface
Applying glue is main by using the material for making film, forms successional film on the surface of paper, the fiber on surface is bonded to paper
Surface, can improve writing property and printability, while substantially increasing the water resistant grease resistance of paper, conventional oxidized starch is made at present
For sizing agent, but oxidized starch, into feminine gender, the affinity with fiber is poor, and the surface strength of paper after applying glue is relatively low, it is impossible to full
Surface high intensity requirement of the sufficient kraft inner paper in specifically used.
The content of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of and kraft inner paper surface fiber conjugation is good, enhancing ox-hide
The gluing reinforcing agent and preparation method of paperboard surface strength.
The present invention is realized by following technological means solves above-mentioned technical problem：
A kind of high-strength cow paperboard surface sizing strengthening agent, it is made up of following masses fraction, includes 30%-40% modified shallow lake
Powder, 15%-20% polyacrylamides, 10%-15% cinnamic acrylic esters, 10%-20% polyvinyl alcohol, 5%-10% carboxymethyl celluloses
Element, 1-5% water soluble sulfates, modified starch total amount 5%-15% crosslinking agent, suitable quantity of water.
One or more of the water soluble sulfate in potassium sulfate, sodium sulphate, aluminum sulfate.
The modified starch is one kind in crosslinked starch, esterified starch, graft starch.
The crosslinking agent is one kind in aluminium chloride, ethylene glycol or phosphoric acid.
Present invention also offers the preparation method for preparing high-strength cow paperboard surface sizing strengthening agent, its making step is such as
Under：
（1）Starch is directly poured under the conditions of 85 DEG C -90 DEG C of starch gelatinization tank and water is gelatinized, and is gelatinized 20-30 minutes, concentration
For 15%-18%, crosslinking agent aluminium chloride hybrid reaction is added after gelatinization complete.
（2）By polyacrylamide, cinnamic acrylic ester, polyvinyl alcohol, carboxymethyl cellulose, water soluble sulfate according to
The solution for standby of 20% concentration is made in secondary add water respectively.
（3）By step（2）In obtained solution be respectively dropped into step（1）In stir, solid content 8-10% is made, viscous
40-50cps or so gluing reinforcing agent is spent, 60 DEG C of constant temperature is waited to be glued.
The advantage of the invention is that：High-strength cow paperboard surface sizing strengthening agent of the present invention, modified starch good hydrophilic property,
And contain hydrophilic group, kraft inner paper intensity, crosslinking agent, polyacrylamide, the addition of cinnamic acrylic ester and fiber can be improved
On hydroxyl formation covalent bond, intensity can be obviously improved paper far above starch and fibroplastic Hydrogenbond intensity after crosslinking
Physical strength, surface sizing starch consumption reduction, reduce adhesiveness in the solid content of table glue, reduction, it is to avoid paper because
The thing that compound viscosity height produces applying glue white line and degraded, polyvinyl alcohol can make have stronger cohesive force between dried fiber,
Improve kraft inner paper surface strength and grease resistance.
