Problems solved by technology

With the development of technology and the improvement of people's living standards, the requirements for leaflets should be as much as possible to attract audience groups so as to play the role of publicity, thereby further expanding the effect of publicity, while the existing advertising papers have no fluorescent effect, Attractive effect is not strong at night
[0003] At the same time, the existing advertising consumables manufacturing process is likely to cause unbalanced surface tension of the paper, and when the coating layer is processed, after a long period of saturation and humidity, the fiber density changes, and the paper width, thickness, length, shrinkage, and stretching of the paper Inconsistent stretching and easy war

Embodiment 1

[0050] A method for manufacturing weather-resistant and waterproof high-quality printing special paper of this embodiment comprises the following steps:

[0051] Step one, prepare preliminary pulp:

[0052] First crush the waste paper pulp fibers, add lye with a concentration of 1.5% to soak for 20 hours, add them to the fiber dissociation device and stir while washing with clean water, and then mix 70 parts by weight of the cleaned waste paper pulp fibers, 10 parts of raw wood pulp, Add 20 parts of bleached kraft softwood pulp to a hydropulper for fiberization and then process it through a conical refiner. The beating degree is 22°SR, and the refining concentration is 4wt%. 2% mature clay suspension, stir well to obtain preliminary pulp;

[0053] The slaking clay suspension is prepared by adding the purified palygorskite clay into an inorganic dilute acid solution for 60 min in a water bath at a temperature of 80°C, then adding sodium lauryl sulfate to the acidified suspensi...

Embodiment 2

[0074] A method for manufacturing weather-resistant and waterproof high-quality printing special paper of this embodiment comprises the following steps:

[0075] Step one, prepare preliminary pulp:

[0076] First crush the waste paper pulp fibers, add 1.5% lye and soak for 30 hours, add them into the fiber dissociation device and stir them while rinsing with clean water, and then mix 90 parts of waste paper pulp fibers, 20 parts of raw wood pulp, Add 30 parts of bleached kraft softwood pulp into a hydropulper for fiberization and then process it through a conical refiner. The beating degree is 24°SR, and the refining concentration is 6wt%. 3% mature clay suspension, stir well to obtain preliminary pulp;

[0077] The slaking clay suspension is prepared by adding the purified palygorskite clay into an inorganic dilute acid solution for 70 minutes in a water bath heat treatment at a temperature of 90°C, then adding sodium lauryl sulfate to the acidified suspension to fully stir,...

Embodiment 3

[0098] A method for manufacturing weather-resistant and waterproof high-quality printing special paper of this embodiment comprises the following steps:

[0099] Step one, prepare preliminary pulp:

[0100] First crush waste paper pulp fibers, add lye with a concentration of 1.5% and soak for 25 hours, add them to a fiber dissociator while rinsing with clear water while stirring, then mix 80 parts by weight of waste paper pulp fibers, 15 parts of raw wood pulp, Add 25 parts of bleached kraft softwood pulp to a hydropulper for fiberization and then process it through a conical refiner. The beating degree is 22-24°SR, and the refining concentration is 4-6wt%. Accounting for 2.5% of the weight of the fiber pulp, the mature clay suspension is stirred evenly to obtain the preliminary pulp;

[0101] The slaking clay suspension is prepared by adding the purified palygorskite clay into an inorganic dilute acid solution for 65 min in a water bath at a temperature of 85°C, then adding ...

Abstract

The invention relates to the field of preparation of consumables of printing products, in particular to a manufacturing method of weather-resistant, waterproof and high-quality special paper for printing. The manufacturing method comprises the following steps of preparation of initial paper pulp, preparation of a toughening additive, preparation of papercopying pulp, preparation of paper blanks, preparation of an adhesive film solution, and applying of the adhesive film layer. The prepared paper has the advantages that the strength is high, and the printing effect is excellent; the water-resistant, oil-resistant, chemical-resistant and aging-resistant properties are realized; the heat insulation property is good; the certain flame-retardant effect is realized; the paper is flat in surface,is difficult to warp, and is suitable for drum printing; by adopting a large amount of waste paper pulp fiber, the resource is saved, the weight of the paper is light, and the certain fluorescent property is realized; when the paper is used as the advertisement paper, the vision effect is improved; the good bacteria-inhibiting and insect-preventing effects are realized; the added components are free from poison and harm, the safe and environment-friendly effects are realized, and the higher practical value and good application prospect are realized.

Description

technical field [0001] The invention relates to the technical field of modern papermaking, in particular to a method for manufacturing weather-resistant and waterproof high-quality printing special paper. Background technique [0002] Advertising leaflets are commonly known as leaflets, single pages, color pages, promotional colors, posters, folding pages, etc. It mainly plays the role of widely advertising the information of the sending unit. Due to its own characteristics, leaflets are often printed in color on special advertising paper. Now the printing technology and printing equipment in this field have developed maturely. With the development of technology and the improvement of people's living standards, the requirements for leaflets should be as much as possible to attract audience groups so as to play the role of publicity, thereby further expanding the effect of publicity, while the existing advertising papers have no fluorescent effect, At night, the attraction ...
