Embodiment 1

[0033] A production method of quick-drying bible paper, comprising the steps:

[0034] (1) Under the protection of nitrogen, the mixture of saponified polyvinyl acetate and dimethoxychlorosilyl propyl isocyanate is added to ethanol at a molar ratio of 1:15 and stirred to form a mixed solution. The amount of the mixture of saponified polyvinyl acetate and dimethoxychlorosilyl propyl isocyanate is 0.2g, the saponification degree of saponified polyvinyl acetate is 40%, and the weight average molecular weight is 5000; After reacting under reduced pressure for 20 hours, a kind of silane-based polymer was obtained after removing ethanol by distillation under reduced pressure;

[0035] (2) Under the protection of nitrogen, add methyl acrylate dropwise into the methanol solution of diethanolamine, wherein the molar ratio of methyl acrylate to diethanolamine is 1:1, react at 40°C for 3 hours to obtain a mixed solution; then add 1 % p-toluenesulfonamide, and trimethylolpropane was adde...

Embodiment 2

[0042] (1) Under the protection of nitrogen, add the mixture of saponified polyvinyl acetate and dimethoxychlorosilyl propyl isocyanate in a molar ratio of 1:10 to ethanol and stir to form a mixed solution. The mixture amount of saponified polyvinyl acetate and dimethoxychlorosilyl propyl isocyanate is 0.05g, the degree of saponification of saponified polyvinyl acetate is 60%, and the weight average molecular weight is 5000; After reacting under reduced pressure for 20 hours, a kind of silane-based polymer was obtained after removing ethanol by distillation under reduced pressure;

[0043] (2) Under the protection of nitrogen, add methyl acrylate dropwise into the methanol solution of diethanolamine, wherein the molar ratio of methyl acrylate to diethanolamine is 1:3, and react at 35°C for 4 hours to obtain a mixed solution; then add 3 % p-toluenesulfonamide, and trimethylolpropane was added dropwise into the mixed solution, methanol was distilled off under reduced pressure, t...

Embodiment 3

[0050] (1) Under the protection of nitrogen, add the mixture of saponified polyvinyl acetate and dimethoxychlorosilyl propyl isocyanate in a molar ratio of 1:13 to ethanol and stir to form a mixed solution. The mixture amount of saponified polyvinyl acetate and dimethoxychlorosilyl propyl isocyanate is 0.1g, the saponification degree of saponified polyvinyl acetate is 50%, and the weight average molecular weight is 3000; After reacting under reduced pressure for 25 hours, a kind of silane-based polymer was obtained after removing ethanol by distillation under reduced pressure;

[0051] (2) Under the protection of nitrogen, add methyl acrylate dropwise into the methanol solution of diethanolamine, wherein the molar ratio of methyl acrylate to diethanolamine is 1:3, react at 38°C for 5 hours to obtain a mixed solution; then add 2 % p-toluenesulfonamide, and trimethylolpropane was added dropwise into the mixed solution, methanol was distilled off under reduced pressure, the tempe...

Abstract

The invention relates to the field of paper manufacturing, in particular to a production method of quick-drying bible paper, comprising the following steps: (1) mixing and stirring fiber raw materials with titanium dioxide, sodium carboxymethyl cellulose, and water; (2) surfing the Forming, pre-dehydration and drying to obtain ultra-thin paper sheets; (3) using adhesives containing silane-based polymers to bond between two ultra-thin paper sheets; (4) polymerizing with branched polyhydroxyl groups Sizing agents, retention aids, and lubricant fillers are double-sided sizing; (5) After dehydration, drying, and calendering, quick-drying Bible paper is obtained. The present invention uses polyhydroxy polymeric sizing agent to sizing the paper, increasing the number of hydroxyl groups on the surface of the paper, improving the water absorption capacity of the paper, ensuring the rapid separation of water and pigment components after the paper absorbs ink, and achieving the effect of quick drying. Hydrogen bonds are formed between the hydroxyl groups on the cellulose on the surface of the paper to increase the strength of the paper; a hydrophobic layer is added in the middle of the paper to ensure that the paper will not show through after absorbing water.

Description

technical field [0001] The invention relates to the field of paper manufacture, in particular to a production method of quick-drying bible paper. Background technique [0002] Bible paper is a kind of high-grade thin printing paper, which is mainly used to print "Bible" books for foreign churches. Water performance, mainly used for printing Bibles, high-end dictionaries, dictionaries, classic books and other books with many pages, high frequency of use, and easy to carry. It is also used to print information materials for air express; since Bible paper is mostly funded by church Donation publishing, high volume and relatively cheap, has spawned low-quantity thin-page Bible readers. [0003] For example, the publication number is CN110565442A "a kind of production method of ultra-low quantitative bible paper", comprising the following steps: mixing the fiber raw material and titanium dioxide homogeneously, then performing beating operation, and then adding filler; diluting t...
