Description

A kind of efficient surface sizing agent and preparation method thereof
Technical field
The present invention relates to technical field of chemical synthesis, more particularly to a kind of preparation method of efficient surface sizing agent.
Background technology
Paper, particularly corrugated paper, the development trend of paperboard are shown:
1)Just develop from high grammes per square metre to low grammes per square metre direction.
2)Wood pulp is replaced using waste paper, but it is high into the intensity difference of paper, hygroscopicity value.
3)The paper quality caused by internal sizing variable factor is more is unstable, class be difficult improve the problem of, So that manufacturer uses or abandoned less internal sizing, the technique made up using top sizing turns into fashion trend.
Sizing agent requirement for above-mentioned top sizing:A) ring crush intensity is improved;B) Cobb values are greatly reduced(Hygroscopicity value); C) it is fast to cure speed, it is desirable to which lower machine is with regard to ripe.
But though present Cypres can improve the certain ring crush intensity of corrugated paper, sizing agent dosage is big, into This height.
A kind of sizing agent disclosed in Chinese patent CN201210136214.2, although curing speed is fast, and do not get damp, Be for corrugated paper ring crush intensity improve it is little.
The content of the invention
A kind of efficient surface sizing agent that the present invention proposes for solution above mentioned problem of the prior art and preparation method thereof, Cobb values, energy rapid aging can be not only greatly reduced in the Cypres, and substantially lower machine is just ripe, and can be in sizing agent dosage The surface that paperboard body paper is increased substantially in the case of constant is strong.
In order to realize above-mentioned technical purpose, the technical measures that the present invention is taken are:
A kind of preparation method of efficient surface sizing agent, comprises the following steps:
Step 1, methyl styrene, acrylic ester monomer, cross-linking monomer, cationic monomer and initiator are mixed equal Even formation mix monomer;
Step 2, the mix monomer obtained is added in 10-20% step 1 in four-hole boiling flask, is warming up to 80-140 DEG C, instead Remaining mix monomer is added dropwise after answering 5-20 minutes, then 80-140 DEG C of insulation 0.5-1.5 hour;
Step 3, add acetic acid, 80-140 DEG C of reaction 20-60 minute;
Step 4, the deionized water of 80-100 DEG C of preheating is added, continue to react 0.5-2 hours, cool down, filtering, obtain height Imitate Cypres.
In order to further optimize above-mentioned technical proposal, the technical measures that the present invention is taken also include:
Further, step 1 proportioning of each component into step 4 is:
