Example Embodiment

[0009] In Example 1, it selects white-backed books, newspapers, newspapers, newspapers, office waste paper, or printing plant scraps and other waste papers, and puts them in a pulper at the ratio of 100 catties of waste paper to 500 catties of water and pulverizes for 5 minutes. Then use steam to heat the pulp in the pulper to 30°C, and while continuing to shred the paper, rinse the eluted ink with water for 30 minutes, and then put the pulp into the pulper for beating while beating , Rinse with water, and then slowly disperse the aniline acid direct green dye into the beating machine 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 Concentrate into the thickener until the paper slurry accounts for at least 25%, then put it into the cavity of a special mold made of wood, use a perforated molding plate to filter out the water and shape it, and then dry it in the shade after ejecting the mold. T...

Example Embodiment

[0010] In Example 2, it selects various yellow old packaging cardboards or scraps from carton factories and other waste papers, and puts them into a pulper at the ratio of 100 catties of waste paper to 600 catties of water and pulverizes them for 8 minutes to make a slurry. , Then use steam to heat the pulp in the pulper to 35°C, and then continue to shred the paper while rinsing with clean water for 40 minutes, and then put the pulp into the pulper for beating, while beating, and then rinsing with water, Then, according to the ratio of 100 catties of waste paper to 0.8 catties of dye, slowly disperse the aniline acidic direct yellow dye into the beating machine, beating and coloring for 20 minutes, and then sending the beaten slurry into the thickening machine. Concentrate the paper slurry to at least 30%, then put it into the cavity of a special mold made of wood, press and filter out the water with a perforated mold plate, and then dry it in the shade to make the finished produ...

Example Embodiment

[0011] Example 3, it selects white background books, newspapers, miscellaneous paper, office waste paper, or printing plant scraps and other waste paper, and puts 100 catties of waste paper into 700 catties of water in a pulper and pulverizes for 10 minutes. Pulp, then use steam to heat the pulp in the pulper to 35°C, and then continue to shred the paper while rinsing with water for 35 minutes, and then put the pulp into the pulper for beating, while beating and rinsing with water , 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 beating machine, beating and coloring for 25 minutes, sending the beaten slurry into the thickening machine Concentrate the paper slurry to at least 35%, then put it into the cavity of a special mold made of wood, use a perforated mold plate to filter out the water and shape 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...
