Technical field
The present invention relates to a kind of sizing agent and preparation method thereof, particularly relate to and a kind ofly there is good stability and sizing agent of the ring crush intensity of paper and preparation method thereof can be significantly improved.
Background technology
Paper, in preparation process, by glue-applying technique, can give the physical property that paper is certain, prevents infiltration and the diffusion of some fluids.Conventional paper is after paper technology terminates, if without applying glue process, the existence in a large amount of spaces is had in the middle of string in paper, and these strings itself are with a large amount of oh groups, due to the existence of these oh groups, when paper and liquid comes into contact, liquid can enter paper inside, affect the intensity of paper, limit effective use of paper.
The range of application of cationic rosin size sizing agent is comparatively wide, and present stage, most cation colophony size was applied to after in paper technology, and the ring crush intensity of paper improves little, still limits widely using of paper.
Summary of the invention
The technical problem solved: conventional sizing agent less stable, and the ring crush intensity of the paper prepared is too low, limits the problem of the use of paper.
Technical scheme: the invention discloses a kind of cationic rosin size sizing agent and preparation method thereof, cationic rosin size sizing agent is made up of according to weight ratio following composition: cationic rosin size is 6 ~ 8 parts, vinyl acetate is 9 ~ 12 parts, polyacrylonitrile is 2 ~ 3 parts, tetradecyl methylacrylate is 5 ~ 6 parts, polyoxyethylene sorbitol acid anhydride tristearate is 12 ~ 15 parts, alum is 3 ~ 4 parts, deionized water is 240 ~ 260 parts.
A kind of preparation method of cationic rosin size sizing agent, preparation method comprises the steps: (1) by stainless steel cauldron heating temperatures to 45 DEG C, in reactor, add after temperature constant that cationic rosin size is 6 ~ 8 parts, vinyl acetate is 9 ~ 12 parts, polyacrylonitrile is 2 ~ 3 parts, tetradecyl methylacrylate is 5 ~ 6 parts, carry out sufficient mechanical agitation, be stirred to and mix; (2) in stainless steel cauldron, add that polyoxyethylene sorbitol acid anhydride tristearate is 12 ~ 15 parts, deionized water is 240 ~ 260 parts again, mechanical agitation oar is used to carry out abundant stirring and emulsifying, be stirred to mixed liquor and become emulsion, continue to stir 30min after becoming emulsion; (3) in stainless steel cauldron, adding alum is 3 ~ 4 parts, carries out stirring abundant reaction, and mixing time is 2h; (4), after reaction terminates, the sizing agent prepared is slowly cooled to room temperature.
The cationic rosin size added in the preparation process of cationic rosin size sizing agent is preferably 8 parts.
The polyoxyethylene sorbitol acid anhydride tristearate added in the preparation process of cationic rosin size sizing agent is preferably 12 parts.
The alum added in stainless steel cauldron in the preparation process of cationic rosin size sizing agent is preferably 4 parts.
Beneficial effect: the present invention prepares cationic rosin size sizing agent and has good stability, under 3000rpm, centrifugal 30 to 50min does not have lamination, heat after 12 to 24h without lamination at 50 DEG C, paper is after sizing agent process of the present invention, ring crush index is increased to 7.9 to 8.2 by 5.3, improves the ring crush intensity of paper.
