preparation example Construction

[0030] In order to solve the above problems, a second aspect of the present invention provides a method for preparing paper containing coffee grounds, comprising the following steps:

[0031] S1. Mix 5-10% of coffee grounds, 80-90% of pulp fiber and water, and obtain pulp stock solution after beating, and the beating degree is 35°-45°SR;

[0032] S2. Add 1-3% of adsorbent, 2-5% of charge regulator, and 1.5-3.5% of retention aid into water in sequence to mix and dilute to obtain a diluent, then add the obtained diluent to the pulp stock solution, stir evenly, and add water Diluted to obtain a molding slurry.

[0033] S3. The forming slurry is formed in a mold to obtain a formed paper blank, and the formed paper blank is hot-pressed to obtain a paper containing coffee grounds.

Embodiment 1

[0037] Embodiment 1 provides a paper containing coffee grounds and a preparation method thereof.

[0038] The preparation raw materials include the following components: 8kg of coffee grounds, 42.5kg of waste paper pulp fibers, 42.5kg of straw pulp fibers, 1kg of wheat flour (purchased from Guangxi Zhechuang Chemical Co., Ltd.), 0.5kg of calcium carbonate, 3kg of polydimethyldiallyl Ammonium chloride (purchased from Kunshan Shengan Biotechnology Co., Ltd., model D1UL), 2.5 kg anionic polyacrylamide (purchased from Shandong Liaocheng Longxing Environmental Protection Technology Co., Ltd., molecular weight is 12 million). Among them, the coffee grounds are coffee grounds that have been roasted at 100° C. for 1.5 hours and ground through a 150-mesh screen.

[0039] The preparation method is as follows:

[0040] S1. Mix: 8kg of coffee grounds, 42.5kg of waste paper pulp fibers, 42.5kg of straw pulp fibers and 1000kg of water, and obtain pulp stock solution after beating. The beati...

Embodiment 2

[0045] Similar to Example 1, a paper containing coffee grounds and a preparation method thereof are provided, but the preparation raw materials are: 5kg of coffee grounds, 44kg of waste paper pulp fibers, 44kg of straw pulp fibers, 1kg of wheat flour, 0.5kg of calcium carbonate, 3kg of polydicarbonate Methyldiallylammonium chloride, 2.5kg anionic polyacrylamide.

Abstract

The invention discloses a paper containing coffee grounds and a preparation method thereof, which is characterized in that, by weight percentage, the preparation raw materials include 5-10% of coffee grounds, 80-90% of pulp fiber, 1-3% of Adsorbent, 2-5% charge regulator, 1.5-3.5% retention aid. The preparation method includes the steps of preparing a pulp stock solution, preparing a forming stock solution, forming a paper blank and hot pressing. The paper prepared by the invention has good strength and toughness and good surface finish, and also has the functions of coffee aroma and deodorization. The coffee grounds, waste paper pulp fibers and straw pulp also avoid the use of wood pulp fibers and protect the ecology resources, reducing costs.

Description

technical field [0001] The invention belongs to the technical field of papermaking, and in particular relates to a paper containing coffee grounds and a preparation method thereof. Background technique [0002] Forests are the precious wealth of the earth. Many of the raw materials for papermaking come from forests, and people's demand for paper is huge, resulting in accelerated consumption of forest resources and damage to the ecological balance. Wrapping paper is a kind of paper commonly used in daily life. In addition to the characteristics of general paper, it also needs a certain strength and better cushioning performance. Even the wrapping paper used in some specific places must have a certain fragrance and can remove odors. . In addition, the world consumes a lot of coffee every year, but the coffee grounds are often discarded as waste, resulting in a great waste of resources and damage to the ecological environment. SUMMARY OF THE INVENTION [0003] In order to s...
