Problems solved by technology

Wood pulp is not only expensive, but more use will increase the cost of papermaking. What is more serious is that wood pulp is obtained from forest trees, and more wood pulp is used on the premise of cutting down more trees.
Therefore, the preparation process of high-strength wrapping paper in the prior art often causes the consumption of many forest resources, and the cost is higher

Embodiment 1

[0019] (1) Seasoning: Prepare a paper mixture, which is seasoned according to the following weight percentages: European waste 22%, American waste 18%, glue 10%, waterproofing agent 8%, dry strength agent 13%, sulfuric acid Aluminum solution 20%, water balance, the waterproofing agent used is mortar waterproofing agent, the concentration of aluminum sulfate solution used is 45%;

[0020] (2) Preparation of pulp: dissolving the prepared paper mixture in step (1) in a pulper to form pulp;

[0021] (3) Impurity removal: the pulp is successively passed through a pressure screen and a slag remover to remove impurities, and the impurity removal temperature is 20°C;

[0022] (4) Beating treatment: input the pulp after impurity removal to a grading sieve, and the grading sieve divides the pulp into long fibers and short fibers, and transports the long fibers to the first grinding disc for beating treatment to obtain long fibers. Fiber slurry, the short fiber is transported to the sec...

Embodiment 2

[0026] Example 2: The rest is the same as in Example 1, except that in the step (1), 21% of European waste, 20% of American waste, 11% of glue, 9% of waterproofing agent, 12% of dry strength agent, Aluminum sulfate solution 18%; in the step (4), the concentration of the wood pulp is 7%.

Embodiment 3

[0027] Example 3: The rest is the same as Example 1, except that in the step (1), 22% of European waste, 19% of American waste, 13% of glue, 10% of waterproofing agent, 14% of dry strength agent, Aluminum sulfate solution 22%; in the step (5), the long-fiber slurry is sent to the first bed of the wire section, and the first bed molds and dehydrates the long-fiber slurry to a dryness of 21 %, the short fiber pulp is sent to the second bed of the wire section, and the second bed molds and dehydrates the short fiber pulp to a dryness of 19%, and the wood pulp pulp Sent to the third bed of the wire section, the third bed molds and dehydrates the wood pulp slurry to a dryness of 23%.

Abstract

The invention discloses a high-strength pouring cup paper preparation technology and relates to the technical field of chemical engineering. The preparation technology comprises seven technology processes of preparing material, preparing paper pulp, removing impurities, pulping, composting paper, squeezing and finishing products. By the use of the manufacturing and processing method, the paper is waterproof and oil-resistant and has high strength; wood pulp use amount can be greatly reduced; compared with a paper preparation method in the prior art, the wood pulp use amount can be reduced by a half, so wood pulp loss can be reduced, cost is lowered and the environment is protected; the high-strength pouring cup manufactured by the preparation technology meets demands of the public; the pouring cup can be made from wide material and simple methods and can be reused; the high-strength pouring cup paper preparation technology responses to a call for the construction of resource-saving and environment-friendly nation; and the pouring cup is suitable for various business fields and all households.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a preparation process of high-strength cup paper. Background technique [0002] Nowadays, papers with waterproof, oil-proof and strong tensile strength are required in many fields. For example, beauty salons need such paper to wrap the neck or face. However, the existing manufacturing process is difficult to produce paper that is waterproof, oil-proof, and highly stretchable. High-strength wrapping paper is an excellent packaging material and one of the components of many packaging boxes and packaging boards. . In the prior art, when producing high-strength packaging paper, in order to meet the strength requirements, it is often necessary to add 10% wood pulp pulp relative to the waste paper pulp. Wood pulp is not only expensive, but more use will increase the cost of papermaking. What is more serious is that wood pulp is obtained from forest trees, and more wood pul...
