Abstract
The invention relates to a paper surface sizing agent and a sizing method thereof. The paper surface sizing agent comprises, by weight, 1-10% of cationic modified starch, 0-1% of alkyl ketene dimmer, 0-0.5% of aluminum sulfate, and the balance being water. The cationic degree of substitution of the cationic modified starch is equal to 0.01-0.1. The paper surface sizing agent prepared with the specific cationic modified starch has high bonding force with paper fibers while having high self-retention rate and high fiber-retention, and further can improve paper picking strength effectively and improve printing property of paper; besides, starch concentration of the paper surface sizing agent can be reduced to that of the oxidized starch utilized at present while paper picking strength is about the same, and thus, comprehensive production cost is lowered and waste water treatment load is reduced, and remarkable economic benefit and environmental benefit are achieved.
Description
Technical field
The present invention relates to sizing agent, more particularly to a kind of paper surface sizing agent and its glue applying method.
Background technology
In paper manufacturing processes, in order to give the good smoothness of paper surface and intensity, generally require in paper table
Face is coated with sizing agent and is surface-treated.
At present, generally adopt Oxytarch as the primary raw material of sizing agent, but Oxytarch is negative, with fiber parent
Poor with property, the surface strength of paper being therefore obtained is bad, and when carrying out broken and copying back, most of sizing agent can enter plain boiled water system
System, makes system bod and cod value increase, impact paper machine is manufactured paper with pulp.In addition, paper mill is also usually entered to native starch with α-amylase
Row heat treated, enzyme optionally can decompose at the Isosorbide-5-Nitrae key of native starch, and its molecular weight is reduced, and reduces dextrin
Viscosity is to meet surface sizing technique requirement, but it is low with the bond strength of fiber, and the viscosity stability of enzyme converted starch is relatively
Difference.
Content of the invention
Based on this it is necessary to while providing one kind to be effectively improved paper surface quality, viscosity stability is good and fiber is tied
Close intensity high, the high paper surface sizing agent of retention.
A kind of paper surface sizing agent, by weight percentage, including following component:
Wherein, the degree ofacationic substitution of described cation modified starch is 0.01～0.1.
Wherein in an embodiment, by weight percentage, including following component:
Wherein in an embodiment, when described cation modified starch is configured to the dextrin of mass concentration 6%: 60 DEG C
Viscosity under temperature conditionss is 23～24cp；Viscosity under 70 DEG C of temperature conditionss is 19～21cp；Viscous under 80 DEG C of temperature conditionss
Spend for 13～16cp.
Wherein in an embodiment, the degree ofacationic substitution of described cation modified starch is 0.01～0.03.
Wherein in an embodiment, described cation modified starch is quaternary ammonium cation modified corn starch.
Wherein in an embodiment, the type of described alkyl ketene dimer is 1860.
The present invention also provides the glue applying method of described paper surface sizing agent, comprises the steps:
Prepare sizing agent: add described cation modified starch in described water, stirring is warming up to 90～100 DEG C, insulation
15～25min, is subsequently cooled to 60～65 DEG C, obtains starch gelatinization liquid；Add described alkyl ketene in described starch gelatinization liquid
Dimer and aluminum sulfate, stir and maintain temperature to be 60～65 DEG C, obtain sizing agent；
Applying glue: described sizing agent is coated on paper, is dried, you can.
Wherein in an embodiment, the described method preparing sizing agent comprises the steps:
Add described cation modified starch in described water, stirring is warming up to 94～96 DEG C, is incubated 18～22min, so
After be cooled to 60～65 DEG C, obtain starch gelatinization liquid；Add described alkyl ketene dimer and sulphuric acid in described starch gelatinization liquid
Aluminum, stirs and maintains temperature to be 60～65 DEG C.
Wherein in an embodiment, the method for described coating is: using coating instrument, in speed 20～30m/min condition
Under be coated.
Wherein in an embodiment, the condition of described drying is: 100～110 DEG C of temperature, time 1～5min.
The method have the advantages that
The present invention passes through using specific cation modified starch, prepares the paper surface sizing agent obtaining and is ensureing paper
Picking strength, improve paper printing performance while, strong with paper fibre adhesion, itself retention rate and fiber retention high,
Starch concentration in paper surface sizing agent can be made to be reduced to about the half of Oxytarch of current employing, and paper fussed intensity
Quite, thus reduce paper production integrated cost and wastewater treatment load, there is significant economic benefit and environmental benefit.With
When, this paper surface sizing agent viscosity stability is good, is conducive to paper product steady quality.
Further this cation modified starch is matched with alkyl ketene two polyketone and aluminum sulfate, paper can be improved further
The affinity of Cypres and fiber and itself retention rate and fiber retention, improve the picking strength of paper, meanwhile, also
Paper can be made to have good water absorption resistance, uniform hue, definition be good, bright in colour after printing, print through is few to make paper.
The glue applying method of the paper surface sizing agent of the present invention, controls the techniques such as starch gelatinization temperature, time by reasonable
Condition, can give full play to the excellent properties of paper surface sizing agent of the present invention, and glue applying method is simple, is easy to practical application.
