Abstract
The invention relates to a papermaking processing aid and a preparation method thereof. The papermaking processing aid is prepared from the following components in parts by weight: 13-15 parts of toluene diisocynate, 2-4 parts of C9 petroleum resin, 9-12 parts of octadecyl phenylsulfonic acid potassium, 1-2 parts of potassium oxalate, 4-5 parts of propylene glycol, 4-6 parts of ethyl acetate, and 120-124 parts of deionized water. The preparation method of the papermaking processing aid disclosed by the invention comprises the following steps: heating and mixing the components, mechanically agitating, and cooling. The tensile strength, the ring crush index and the performance parameter of paper can be greatly improved by the prepared papermaking processing aid.
Description
Technical field
The present invention relates to a kind of papermaking processing aid and preparation method thereof, particularly relate to and a kind ofly can promote largely the tensile strength of paper and papermaking processing aid of ring crush index and preparation method thereof.
Background technology
In the process of papermaking, can use a lot of processing aids, as filter aid, dry strength agent, wet strength agent, sizing agent etc.These different auxiliary agents have different functions, and common use can improve the quality of paper product.In the production process of papermaking, the function of certain auxiliary agent is comparatively limited conventionally, can not meet the needs of production completely.
Dry strength agent and wet strength agent are applied in dry strong tensile strength and the wet strong tensile strength that in paper industry, can improve paper, but dry strength agent and wet strength agent can not effectively promote the ring crush intensity of paper, sizing agent can improve the ring crush intensity of paper, but sizing agent can not improve the tensile strength of paper, if the tensile strength that therefore processing aid not only can improve paper can also improve an epoxy intensity for paper, can have and utilize preferably space.
Summary of the invention
The technical problem solving: common processing aid is applied in the production of paper, to the tensile strength of paper with change Compressive Strength and promote less problem.
Technical scheme: in order to promote surface strength and the ring crush index of paper simultaneously, the invention discloses a kind of papermaking processing aid and preparation method thereof, papermaking processing aid is made up of according to weight ratio following composition: toluene di-isocyanate(TDI) is that 13～15 parts, C9 Petropols are that 2～4 parts, octadecyl benzene sulfonic acid potassium are that 9～12 parts, potassium oxalate are that 1～2 part, propylene glycol are that 4～5 parts, ethyl acetate are that 4～6 parts, deionized water are 120～124 parts.
A kind of preparation method of papermaking processing aid, preparation method comprises the steps: that temperature of reaction kettle is adjusted to 70 ℃ by (1), getting toluene di-isocyanate(TDI) and be 13～15 parts, C9 Petropols and be 2～4 parts, octadecyl benzene sulfonic acid potassium is 9～12 parts, toluene di-isocyanate(TDI), C9 Petropols and octadecyl benzene sulfonic acid potassium are dropped in reactor, use mechanical agitation oar to stir, be stirred to evenly; (2) be that 120～124 parts, propylene glycol are 4～5 parts to adding deionized water in reactor again, again carry out mechanical agitation to evenly; (3) finally to add potassium oxalate after be evenly that 1～2 part, ethyl acetate are 4～6 parts to mixed liquor state, is stirred to evenly with mechanical agitation oar, at 70 ℃, protects 3h; (4) be cooled to after room temperature, prepare papermaking processing aid.
Wherein, the toluene di-isocyanate(TDI) adding in the preparation method of papermaking processing aid is preferably 14～15 parts.
Wherein, the C9 Petropols molecular weight adding in the preparation method of papermaking processing aid is preferably 300～3000.
Wherein, the potassium oxalate adding in the preparation method of papermaking processing aid is preferably 2 parts.
Beneficial effect: the papermaking processing aid that the present invention prepares is coated on after paper surface, the dry strong tensile strength of paper is increased to 56.1 to 58.6Nm/g by 25.7Nm/g, wet strong tensile strength is increased to 24.8 to 26.1Nm/g by 12.2Nm/g, the ring crush index of paper is increased to 5.3 Nm/g to 5.6 Nm/g by 2.2 Nm/g, not only improve the tensile strength of paper, also improved the ring crush intensity of paper.
