Abstract
The invention discloses a kind of Cypres of paper grade (stock), specifically a kind of Cypres and preparation method thereof.It includes that the raw material of following weight portion is constituted：9 15 parts of polyacrylic acid, 15 20 parts of N NMAs, 58 parts of ammonium persulfate, 35 parts of acrylamide, 10 15 parts of initiator, 35 parts of emulsifying agent, 68 parts of styrene, 6 10 parts of glyoxal.After adopting with the aforedescribed process, as a result of rational manufacture method, various composition is set to be sufficiently mixed reaction, rational composition is with the addition of in production process, it is homogeneous, can improve paper performance obvious, in addition, its rational formula causes that in production process harmful substance will not be produced, avoid the pollution to environment and the injury to human body, but also the cost of production can be reduced, rationally control reaction temperature in process of production in addition and the time obtains and can improve paper quality.
Description
Technical field
The present invention relates to a kind of Cypres of paper grade (stock), specifically a kind of Cypres and its preparation side
Method.
Background technology
Top sizing is not to be completely dried one layer of glue of some strength of spraying in paper, by the table after drying in paper
Face forms one layer of glued membrane, and the purpose of paper surface property is changed so as to reach, it be in paper finishing processes after paper drying
One important operation, although top sizing can improve paper performance, but formula and the preparation of existing Cypres
Method is unreasonable, not only pollutes the environment, and influences health and paper performance improvement is not apparent.
The content of the invention
The technical problem to be solved in the present invention provides a kind of homogeneous, safety and environmental protection and paper performance improves obvious table
Surface sizing agent and preparation method thereof.
In order to solve the above-mentioned technical problem, Cypres of the invention, including the raw material of following weight portion is constituted：Poly- third
Olefin(e) acid 9-15 parts, N hydroxymethyl acrylamide 15-20 parts, ammonium persulfate 5-8 parts, acrylamide 3-5 parts, initiator 10-15 parts,
Emulsifying agent 3-5 parts, styrene 6-8 parts, glyoxal 6-10 parts.
Above-mentioned Cypres, including the raw material of following weight portion is constituted：12 parts of polyacrylic acid, N- methylol acryloyls
17 parts of amine, 6 parts of ammonium persulfate, 4 parts of acrylamide, 12 parts of initiator, 4 parts of emulsifying agent, 7 parts of styrene, 8 parts of glyoxal.
A kind of preparation method of above-mentioned Cypres, comprises the following steps：
A, by above-mentioned raw materials polyacrylic acid, N hydroxymethyl acrylamide, ammonium persulfate and emulsifying agent be added in reactor mix
Stirring is closed, controls the temperature in reactor for 85-90 DEG C, after stirring, obtain mixed liquor standby；
B, initiator for reaction 1-2 hour will be added in mixed liquor, be subsequently adding acrylamide, styrene, 5-1 DEG C of glyoxal cooling
And stir, it is sufficiently stirred for rear heat temperature raising more than 95 DEG C, continue to react 0.3-0.8 hours；
After C, reaction terminate, insulation stands after 3-5 hours, then by air-cooled from after normal temperature.
After adopting with the aforedescribed process, as a result of rational manufacture method, various composition is set to be sufficiently mixed reaction,
Rational composition is with the addition of in production process, it is homogeneous, can improve paper performance obvious, in addition, its rational formula
So that harmful substance will not be produced in production process, it is to avoid the pollution to environment and the injury to human body, but also can subtract
The cost of few production, rationally controls reaction temperature and the time obtains and can improve paper matter in process of production in addition
Amount.
