Abstract
The invention relates to a cationic rosin size sizing agent and a preparation method thereof. The cationic rosin size sizing agent is prepared from the following components in parts by weight: 6-8 parts of cationic rosin size, 9-12 parts of acetic acid vinyl ester, 2-3 parts of polyacrylonitrile, 5-6 parts of tetradecyl methacrylate, 12-15 parts of polyoxyethylene sorbitan tristearate, 3-4 parts of white alum and 240-260 parts of deionized water. The preparation method of the cationic rosin size sizing agent comprises the following steps: heating, complexing, reacting, and cooling. The prepared cationic rosin size sizing agent has good centrifugal stability and high-temperature stability, and the ring crush compression resistance of paper can be obviously improved.
Description
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 can significantly improve sizing agent of the ring crush intensity of paper and preparation method thereof.
Background technology
Paper, in preparation process, by glue-applying technique, can give paper certain physical property, prevents infiltration and the diffusion of some fluids.Conventional paper is after paper technology finishes, if do not pass through applying glue processing, in paper, in the middle of string, have the existence in a large amount of spaces, and these strings itself are with a large amount of oh groups, due to the existence of these oh groups, in the time that paper contacts with liquid, liquid can enter paper inside, affect the intensity of paper, limited effective use of paper.
The range of application of cation colophony glue sizing agent is wider, present stage most cation colophony sizes after being applied in paper technology, the ring crush intensity of paper improves little, is still limiting being widely used of paper.
Summary of the invention
The technical problem solving: conventional sizing agent less stable, and the ring crush intensity of the paper preparing is too low, has limited the problem of the use of paper.
Technical scheme: the invention discloses a kind of cation colophony glue sizing agent and preparation method thereof, cation colophony glue sizing agent is made up of according to weight ratio following composition: cation colophony glue is that 6～8 parts, vinyl acetate are that 9～12 parts, polyacrylonitrile are that 2～3 parts, tetradecyl methylacrylate are that 5～6 parts, polyoxyethylene sorbitol acid anhydride tristearate are that 12～15 parts, alum are that 3～4 parts, deionized water are 240～260 parts.
A kind of preparation method of cation colophony glue sizing agent, preparation method comprises the steps: that stainless steel cauldron temperature is heated to 45 ℃ by (1), in the backward reactor of temperature constant, adding cation colophony glue is that 6～8 parts, vinyl acetate are that 9～12 parts, polyacrylonitrile are that 2～3 parts, tetradecyl methylacrylate are 5～6 parts, carry out sufficient mechanical agitation, be stirred to and mix; (2) be that 12～15 parts, deionized water are 240～260 parts to adding polyoxyethylene sorbitol acid anhydride tristearate in stainless steel cauldron again, use mechanical agitation oar to carry out abundant stirring and emulsifying, being stirred to mixed liquor becomes emulsion, becomes and continues to stir 30min after emulsion; (3) be 3～4 parts to adding alum in stainless steel cauldron, stir abundant reaction, mixing time is 2h; (4) after reaction finishes, the sizing agent that preparation is completed slowly cools to room temperature.
The cation colophony glue adding in the preparation process of cation colophony glue sizing agent is preferably 8 parts.
The polyoxyethylene sorbitol acid anhydride tristearate adding in the preparation process of cation colophony glue sizing agent is preferably 12 parts.
In the preparation process of cation colophony glue sizing agent, be preferably 4 parts to the alum adding in stainless steel cauldron.
Beneficial effect: the present invention prepares cation colophony glue sizing agent and has good stability, under 3000rpm, centrifugal 30 to 50min do not have lamination, heat 12 to 24h at 50 ℃ after without lamination, after paper is processed through sizing agent of the present invention, ring crush index is increased to 7.9 to 8.2 by 5.3, has improved the ring crush intensity of paper.
