Embodiment 1

[0009] Embodiment 1, it selects waste papers such as books, periodicals and newspapers with a white background, office waste paper or printing factory scraps, puts 100 jin of waste paper into 500 jin of water together and pulverizes it in a pulper for 5 minutes to make Slurry, then use steam to heat the slurry in the pulper to 30°C, and then continue to shred paper, while rinsing the ink that has been removed with water for 30 minutes, and then put the pulp liquid into the pulper for beating, while beating 1. While rinsing with water, slowly disperse the aniline acidic direct green dye into the beater according to the ratio of 100 catties of waste paper to 1 catty of dye, while beating and coloring for 15 minutes, send the beaten slurry to Thicken it into the concentrator until the paper pulp accounts for at least 25%, and then put it into the cavity of a special mold made of wood, pressurize and filter the water with a molded plate with holes on it, and then dry it in the shad...

Embodiment 2

[0010] Embodiment 2, it selects waste papers such as various old packing box cardboards of yellow or carton factory leftovers, puts into the pulper together in the ratio of adding 600 jin of water to 100 jin of waste paper and pulverizes it for 8 minutes to make slurry , and then use steam to heat the pulp in the pulper to 35°C, and then continue to shred the paper while rinsing it with clean water for 40 minutes, then put the pulp liquid into the pulper for beating, and then rinse with water while beating. Then, according to the proportion of 100 catties of waste paper to 0.8 catties of dye, slowly disperse the aniline acidic direct medium yellow dye into the beater, beat and color for 20 minutes, and send the beaten pulp into the thickener Concentrate until the paper pulp accounts for at least 30%, and then put it into the cavity of a special mold made of wood, pressurize and filter the water with a molded plate with holes on it, and then dry it in the shade to make the finis...

Embodiment 3

[0011] Embodiment 3, it selects waste papers such as books, periodicals and newspapers with a white background, office waste paper or printing factory scraps, puts 100 jin of waste paper into 700 jin of water together and pulverizes it in a pulper for 10 minutes to make Then use steam to heat the pulp in the pulper to 35°C, and then continue to shred paper while rinsing with water for 35 minutes, then put the pulp liquid into the pulper for beating, and rinse with water while beating , and then according to the ratio of 100 catties of waste paper to 1.5 catties of dye, slowly disperse the aniline acid direct green dye into the beater, while beating and coloring for 25 minutes, send the beaten pulp into the thickener Concentrate until the paper pulp accounts for at least 35%, and then put it into the cavity of a special mold made of wood, pressurize and filter the water with a molded plate with holes on it, and then dry it in the shade to make the finished product .

Abstract

Paper-packing mats are prepared by: selecting waste paper, crushing to pulp, heating while crushing, rinsing at least 20 minutes, relieving water and washing while pulping in beating machine, adding aniline acid direct green or mid-yellow dye into beater with ratio of waste paper 100 parts to dye 0.8 parts, painting while beating, concentrating into 25% of paper pulp in concentrating machine, putting it into internal cavity of a mold, pressing and filtrating to remove water to be molded, drying in the shade to obtain the products. The advantages includes simple process, low cost, well firmness of product, elasticity exceeding prior foamed mats, capable of recycling, and no environmental pollution.

Description

technical field [0001] The invention relates to a method of recycling waste paper to make packing pads, which belongs to the manufacturing method of paper packing pads. Background technique [0002] Most of the existing article packaging adopts foam pads. This kind of foam pad is made of chemical substances through foaming and other processes. Because the production and molding process of this foam pad is simple, it can be conveniently made into various shapes of packaging pads, and its finished product has certain elasticity, so it is widely used. Packaging of items, especially household appliances. But there is a fatal shortcoming in this foam pad, which is exactly an environmental protection problem. The foam pad belongs to plastic and rubber products. After being molded and used once, it is difficult to recycle and recycle, and it is easy to cause environmental pollution. Contents of the invention [0003] The purpose of the present invention is to overcome the above...
