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) Slurry ratio: prepare a paper mixture, and the paper mixture is prepared according to the following weight percentages: 30% of masson pine, 25% of bagasse, and the amount of dispersed rosin gum (produced in Arakawa, Wuzhou) is 10% %, waterproofing agent 10%, dry strength agent 10%, aluminum sulfate solution 15%, water balance;

[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 second grinding disc for beating treatment, t...

Embodiment 2

[0026] Example 2: The rest are the same as in Example 1, except that in the step (1), 40% of masson pine, 10% of bagasse, 10% of dispersed rosin gum (produced by Arakawa, Wuzhou), 10% of water repellent, 10% of dry strength 10% agent, 20% aluminum sulfate solution; in the step (4), the concentration of the wood pulp is 7%.

Embodiment 3

[0027] Example 3: The rest are the same as in Example 1, except that in the step (1), 10% of the pine pine, 40% of bagasse, 10% of dispersed rosin gum (produced by Wuzhou Arakawa), and 10% of waterproofing agent , dry strength agent 10%, aluminum sulfate solution 20%; in the step (5), the long-fiber slurry is sent to the first bed of the wire part, and the first bed sends the long-fiber slurry Forming and dehydration to dryness is 21%, and the short fiber slurry is sent to the second bed of the wire section, and the second bed is formed and dehydrated to dryness of the short fiber slurry to be 19%. The wood pulp slurry is sent to the third bed of the wire section, and the third bed molds and dehydrates the wood pulp slurry to a dryness of 23%.

[0028] After the above process steps, the outlet cup paper samples are taken out to be tested:

Abstract

The invention relates to the technical field of chemical industry, and particularly relates to a preparation technology of paper cup raw paper. The paper cup technology includes seven technological processes of pulp material proportioning, paper pulp preparation, impurity removal, pulping treatment, paper compositing, squeezing and finished product obtaining; the production and processing method of the paper enables the prepared paper to prevent water and oil and have high strength, and at the same time, the use amount of the wood pulp is greatly reduced; compared with a conventional paper preparation method, the method can make the use amount of the wood pulp reduced by half, and has the advantages of low consumption of the wood pulp, low cost and environmental protection; moreover, the high-strength cup paper prepared by the preparation technology meets the popular demand, has the advantages of wide material sources and simple preparation method, also can be used for second time, and responses to calls of the nation on resource-saving and environment-friendly country construction; and the cup paper can be applicable in various business fields and thousands-of-households resident houses.

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...
