preparation example Construction

[0030] The present invention provides a method for preparing coffee-flavored paper according to the above technical solution, which includes the following steps:

[0031] Mix the pulp fiber, waste paper scraps, coffee grounds and water to obtain the original pulp liquid after beating;

[0032] Mixing the pulp stock solution with an adsorbent, and then sequentially performing dilution and charge balancing treatments to obtain a shaped slurry;

[0033] Using a vacuum suction method to shape the molding slurry to obtain a molding paper blank;

[0034] The formed paper blank is subjected to hot press forming to obtain paper with coffee aroma.

[0035] In the present invention, pulp fiber, waste paper scraps, coffee grounds and water are mixed, and the pulp liquid is obtained after beating. The present invention has no special requirements on the amount of water, and a pulp stock solution with a mass concentration of 8-12% can be obtained; the mass concentration of the pulp stock solution i...

Embodiment 1

[0042] a. Mix corn flour, cassava flour and vinyl acetate with water in a mass ratio of 50:50:3 (the mixture is based on 100 parts by mass, and the water accounts for 80-85%), and the total mass of raw materials is 25kg at 80°C. Stir for 30 minutes to obtain adsorbent;

[0043] b. Put 1000kg of water into the beating barrel and add 20kg waste paper scraps (white paper edge), 70kg pulp fiber (i.e. natural raw wood pulp), 10kg coffee grounds, and continue beating for 45min at 900r / min to make the pulp The fiber and coffee ions are fully combined, and 25kg of the adsorbent prepared above is added, and the pulp stock solution is obtained after uniform mixing;

[0044] c. Pour the pulp stock solution into the mixing tank, add 9000kg of clean water to dilute (the mass concentration after dilution can be controlled within the range of 1 to 1.5%), then test the charge of the diluted slurry, and add a charge balance agent according to the test results to make the pulp When the material is ...

Embodiment 2～3

[0048] The coffee-flavored paper was prepared according to the method of Example 1, and the amount of raw materials is shown in Table 1.

Abstract

The invention belongs to the technical field of recycling and reusing of coffee grounds, and specifically relates to paper with coffee flavor and a preparation method and application thereof. The paper with the coffee flavor provided by the invention is prepared from the following raw materials in parts by mass: 50-70 parts of pulp fibers, 15-25 parts of waste paper scraps, 6-13 parts of the coffee grounds, 4-5 parts of an adsorbent and 5-15 parts of a charge balancing agent. According to the paper with the coffee flavor and the preparation method and application thereof, the coffee grounds are used as one of the raw materials of papermaking, so that the paper has the coffee flavor and has the function of removing odor; meanwhile, the use of the coffee grounds also improves the physical and mechanical strength of the paper; the use of the coffee grounds and the waste paper scraps reduces the use amount of pulp raw materials and reduces papermaking cost.

Description

Technical field [0001] The invention belongs to the technical field of coffee ground recycling and reuse, and in particular relates to a paper with coffee aroma and a preparation method and application thereof. Background technique [0002] Coffee grounds are the solid residues of coffee obtained by grinding and brewing coffee beans. At this stage, the use of coffee grounds is more diversified: coffee grounds have a fluffy structure and can be used to remove peculiar smells; coffee grounds contain a lot of nitrogen compounds, which can Fertilizers are incorporated into the soil where plants grow; the smell of coffee grounds also has an anti-insect effect; in addition, coffee grounds can also be used as a detergent. The above-mentioned application method is to directly use coffee grounds to solve problems in life, and there are few reports of using coffee grounds in industrial production. Summary of the invention [0003] The purpose of the present invention is to provide a paper ...
