Description

Technical Field

[0001] The invention relates to the technical field of bobbin paper, in particular to wear-resistant and waterproof bobbin paper and a preparation method thereof. Background Art

[0002] Tube paper is a common paper product in people's lives. It is mostly used to make tube paper tubes used in the textile industry. At the same time, tube paper is mainly used in the production of cores and pipes, industrial pipes, mulch pipes, firework pipes, textile pipes, spiral pipes, pagoda pipes, parallel pipes, various paper corner protectors, cartons, honeycomb paperboards, etc. Compared with other types of paper, the pulp required for tube paper is relatively cheap. Most of them are made of various waste paper pulps or biological raw material pulps. The main use of tube paper is not suitable for high-demand environments. Therefore, tube paper does not have very high requirements for raw materials and manufacturing processes. Some waste residues and waste paper can be reprocessed and used to reduce production costs, while reducing the consumption of logs and protecting the environment.

[0003] During the production of the tube paper, due to its poor softness, the tube is easily torn during rewinding, which affects the quality of the tube paper. At the same time, the tube paper does not have the function of being waterproof and wear-resistant, so the waterproof and wear-resistant effects of the tube paper are poor during use.

[0030] The method for preparing the wear-resistant and waterproof bobbin paper is characterized by comprising the following steps:

[0031] S1. Beating: placing waste paper pulp and wood pulp into a pulp pool for stirring and beating, so that the waste paper pulp and wood pulp can be mixed, the weight ratio of waste paper pulp to wood pulp is 5%-10%, the pulp beating cycle is 2-4 minutes, and the pulp concentration is 4%-7%. The mixing of waste paper pulp and wood pulp can improve the quality of bobbin paper;

[0032] S2, adding dyes for color adjustment: after the waste paper pulp and wood pulp are beaten, the required dyes can be added into the pulp pool. After the dyes are added, the waste paper pulp and wood pulp are stirred again to make the dyes, waste paper pulp and wood pulp mixed for coloring. The dyes are used to dye the pulp, thereby improving the beauty of the bobbin paper.

[0033] S3, forming: when the waste paper pulp and wood pulp are completely colored, a long mesh plate is placed inside the pulp pool, the long mesh plate is swung back and forth so that the waste paper pulp and wood pulp can be precipitated on the surface of the long mesh plate, and rubber particles are spread on the surface of the waste paper pulp and wood pulp. When the spreading of the rubber particles is completed, a nylon mesh can be placed on the surface of the rubber particles to fit the surface of the waste paper pulp and wood pulp, and the grid of the nylon mesh is filled with rubber particles.
