example 1

[0017] Weigh 100kg of pine wood and crush it for 20 minutes and pass it through a 100-mesh sieve to obtain pine wood powder. Dry the pine wood powder and put it into a combustion furnace with a condenser. Preheat it at 130°C for 30 minutes, then raise the temperature to 220°C, and turn on the combustion. The condensing pipe valve on the furnace allows the flue gas generated by combustion to be condensed into the condensing tank from the condensing pipe to obtain condensate, and then add 25% of the condensate mass to the condensing tank with a mass fraction of 40% sodium hydroxide solution, and let it stand After 4 hours of stratification, the wood tar in the upper layer was separated and set aside; 300g of spider silk was collected and sterilized under an ultraviolet sterilizing lamp for 1 hour, then 100g of tea leaves were weighed and added to a ceramic pot filled with 1L of water, heated and boiled, and then simmered for 7 hours. After boiling, filter and remove the filter re...

[0023] Weigh 150kg of pine wood and crush it for 25 minutes and pass it through a 100-mesh sieve to obtain pine wood powder. Dry the pine wood powder and put it into a combustion furnace with a condenser. Preheat at 140°C for 35 minutes, then raise the temperature to 235°C, and turn on the combustion The condensing pipe valve on the furnace allows the flue gas generated by combustion to be condensed into the condensing tank from the condensing pipe to obtain condensate, and then add 25% of the condensate mass to the condensing tank with a mass fraction of 40% sodium hydroxide solution, and let it stand After stratification for 5 hours, the upper layer of wood tar was separated and set aside; 350g of spider silk was collected and sterilized under an ultraviolet sterilizing lamp for 1 hour, and then 150g of tea leaves were weighed and added to a ceramic pot filled with 2L of water, heated and boiled, and then simmered for 8 hours.

Abstract

The invention discloses a preparation method of a water-resistant and anti-shedding printing paper coating, which belongs to the technical field of printing paper coatings. The invention provides a method of extracting wood tar from pine wood, mixing spider silk and tea leaves for enzymolysis, then mixing and fermenting the enzymolysis solution, nano-montmorillonite and wood tar, and finally adding coupling A method for preparing printing paper coatings with additives and surfactants. In the present invention, spider silk protein is used as the adhesive matrix of the coating, and the number of lipophilic ester groups in the adhesive matrix is ​​increased after wood tar modification, so that the coating not only improves water resistance, but also increases the absorption of ink, and then By adding nano-montmorillonite, the ink-absorbing ability and weather resistance of the coating are enhanced, and it is not easy to change color. Finally, a large number of active groups produced during the microbial fermentation process can form chemical bonds with the active groups on the surface of the paper base and form a network crosslink. structure, thereby solving the problem of paint falling off easily, and has broad application prospects.

Description

technical field [0001] The invention discloses a preparation method of a water-resistant and anti-shedding printing paper coating, which belongs to the technical field of printing paper coatings. Background technique [0002] With the continuous improvement of people's material living standards, the popularization of computers in families and the widespread use of digital cameras, inkjet printing technology has become more and more widely used. In order to obtain more realistic and exquisite pictures, color inkjet printing must be used ink paper as the printing medium. In recent years, the demand for color inkjet printing paper has been increasing day by day, and the color inkjet printing paper in my country's market is mainly imported. [0003] Color inkjet printing paper, like other coated processed papers, is based on raw paper, and the paint prepared by pigments, adhesives and various chemical auxiliary agents is coated on the paper surface with a coating machine.
