Problems solved by technology

[0009] The purpose of the present invention is to provide a method for manufacturing bobbin paper, mixing distiller's grains, corn stalks and waste paper (waste newspaper, carton paper, etc.), adding an appropriate amount of reinforcing agent and filler to make bobbin paper, so as to solve the existing problems. The production of recycled paper from waste paper reduces the production cost, the product quality is poor, and the use requirements cannot be met.

Embodiment 1

[0033] Crush the mature corn stalks and mix them with distiller's grains at a mass ratio of 1:1, add water to dilute to a concentration of 11%, then add compound mold with a mixed liquid quality of 1‰, ferment and hydrolyze for 40 minutes at room temperature to obtain fermented The mixed liquid after fermentation, wherein the upper layer of the fermented mixed liquid is lignin, the middle layer is semi-fiber, and the lower layer is fiber with a fiber length between 0.55 and 1.45 mm. The fibers in the lower layer are removed and cleaned, and dehydrated until the water content is 70% to 80%. in between.

[0034] Take 400kg of fiber pulp obtained through the above treatment and 600kg of waste paper pulp and mix them uniformly at a ratio of 4:6, add water to dilute to a concentration of 1-1.5%, add 4kg of reinforcing agent polyvinyl alcohol, 4kg of waterproofing agent AKD, and adhesive 4kg of polyacrylamide, 12kg of preservative, and 24kg of stone powder, after mixing and stirring...

Embodiment 2

[0036] Grind mature corn stalks and mix them with distiller's grains at a mass ratio of 1:1, add water to dilute to a concentration of 25%, then add compound mold with a mixed liquid quality of 1.5‰, ferment and hydrolyze at room temperature for 50 minutes, and obtain fermented The mixed liquid after fermentation, wherein the upper layer of the fermented mixed liquid is lignin, the middle layer is semi-fiber, and the lower layer is fiber with a fiber length between 0.55 and 1.45 mm. The fibers in the lower layer are removed and cleaned, and dehydrated until the water content is 70% to 80%. in between. .

[0037] Take 200kg of the fiber pulp obtained through the above treatment and 800kg of waste paper pulp and mix them uniformly at a ratio of 2:8, add water to dilute to a concentration of 1.5-2%, add in turn 10kg of reinforcing agent polyvinyl alcohol, 10kg of waterproofing agent AKD, and adhesive 30kg of polyacrylamide, 15kg of preservative, and 30kg of stone powder, after m...

Embodiment 3

[0039]Crush the mature corn stalks and mix them with distiller's grains at a mass ratio of 1:1, add water to dilute to a concentration of 15%, then add compound mold with a mixed liquid quality of 1.2‰, ferment and hydrolyze at room temperature for 45 minutes to obtain fermented The mixed liquid after fermentation, wherein the upper layer of the fermented mixed liquid is lignin, the middle layer is semi-fiber, and the lower layer is fiber with a fiber length between 0.55 and 1.45 mm. The fibers in the lower layer are removed and cleaned, and dehydrated until the water content is 70% to 80%. in between.

[0040] Take 300kg of fiber pulp obtained through the above treatment and 700kg of waste paper pulp and mix them uniformly at a ratio of 3:7, add water to dilute to a concentration of 1.3-2%, add 10kg of reinforcing agent polyvinyl alcohol, 10kg of waterproofing agent AKD, and adhesive 30kg of polyacrylamide, 15kg of preservative, and 30kg of stone powder, after mixing and stir...

Abstract

The invention relates to a method for manufacturing paper by recycled paper, in particular to a manufacturing method of bobbin paper. The manufacturing method of the bobbin paper comprises the steps of fermenting, cleaning and dehydrating vinasse residue and corn straws separately, removing impurities, retaining plant fibers, mixing with waste paper according to a ratio being (2-4):(6-8), adding paper-making aids properly and producing the bobbin paper. According to the method, the production waste, such as the vinasse residue, the corn straws and the waste paper pulp, are completely utilized to produce the bobbin paper, so the method is low in cost, simple and convenient to operate and high in product stability; the vinasse residue and the waste paper pulp are used to realize waste utilization and the corn straw are used to prolong the value chain of corn, so good social benefit and environmentally-friendly benefit are achieved.

Description

technical field [0001] The invention relates to a method for making paper from waste paper, in particular to a method for manufacturing bobbin paper. Background technique [0002] Waste paper treatment is the process of reprocessing recycled waste paper to obtain qualified fibers for the production of paper products. The recycling of waste paper is conducive to protecting the environment, protecting forests and saving resources. Waste paper recycling is one of the effective ways to solve the current shortage of domestic papermaking raw materials, improve papermaking production capacity, and reduce papermaking environmental pollution. It is in line with the goals of the new era and relevant industrial policies. [0003] Using waste paper to produce bobbin paper is a waste paper recycling project that turns waste into treasure. It can solve the contradiction that the shortage of wood fiber in my country restricts the development of the paper industry. Compared with traditiona...
