Description
Technical field
The present invention relates to a kind of sizing agent and preparation method thereof, particularly relate to and a kind of there is higher degree of sizing the compound sizing agent that can significantly improve the folding strength of paper and preparation method thereof.
Background technology
Conventional paper is after repeatedly crimping, and paper there will be the phenomenon of splitting, and the existence of this phenomenon have impact on the use of paper.Folding strength index investigates an important parameter of paper quality.The folding strength improving paper has larger meaning, and the application approach with the paper of higher folding strength can be wider.
Sizing agent is being applied to after in paper, can have larger effect to the physical property of paper.Can improve the folding strength of paper in sizing agent certain limit, but the lifting of folding strength is less, therefore needs to develop new compound sizing agent, while raising degree of sizing, improve the folding strength of conventional paper.
Summary of the invention
The technical problem solved: conventional sizing agent degree is lower, conventional sizing agent is being applied to the problem that after in paper, the folding strength of paper is lower.
Technical scheme: the invention discloses a kind of compound sizing agent and preparation method thereof, compound sizing agent is made up of according to weight ratio following composition: alkenyl succinic anhydride is 7 ~ 10 parts, lauryl amine polyoxyethylene ether is 13 ~ 16 parts, ethyl caprate is 3 ~ 5 parts, Isooctyl acrylate monomer is 5 ~ 6 parts, potassium chloride is 2 ~ 4 parts, chlorinated paraffin wax is 2 ~ 3 parts, deionized water is 190 ~ 210 parts.
A preparation method for compound sizing agent, preparation method comprises the steps: (1), and potassium chloride is 2 ~ 4 parts, and with micronizer, potassium chloride being crushed to order number is 250 ~ 300 object powder; (2) open reactor under room temperature, in reactor, add that alkenyl succinic anhydride is 7 ~ 10 parts, lauryl amine polyoxyethylene ether is 13 ~ 16 parts, ethyl caprate is 3 ~ 5 parts, fully mix; (3) in reactor, add that Isooctyl acrylate monomer is 5 ~ 6 parts, chlorinated paraffin wax is 2 ~ 3 parts, deionized water is 190 ~ 210 parts again, again fully mix, after mixing, carry out frame type stirring by Frame type stirrer, be stirred to evenly; (4) finally add the potassium chloride powder of 250 ~ 300 object 2 ~ 4 parts, again carry out frame type stirring, room temperature preservation after stirring.
Use micronizer potassium chloride to be crushed to order number in the preparation process of compound sizing agent and be preferably 250 orders.
The alkenyl succinic anhydride added in the preparation method of compound sizing agent is preferably 10 parts.
The deionized water added in the preparation method of compound sizing agent is preferably 190 ~ 200 parts.
Beneficial effect: the present invention prepares compound sizing agent and has higher degree of sizing, stockigt method is adopted to determine degree of sizing, degree of sizing is 72s to 73s, and the folding strength of the paper after sizing agent process of the present invention is significantly enhanced, and has risen to 91 to 96 times from 43 times.
