[0011] (III) Beneficial Effects

[0012] In summary, this utility model has at least one of the following beneficial technical effects:

[0013] 1. This multi-layer thickened water-based coated paper provides basic strength and toughness in the base layer, while the tear-resistant lines connecting the top and bottom enhance tear resistance, reducing paper damage caused by tearing and improving paper durability. It can meet the needs of applications with high strength requirements, such as packaging heavy items.

[0014] 2. This multi-layer thickened water-based coated paper features an environmentally friendly and pollution-free water-based coating and water-based acrylic emulsion, conforming to the concept of modern green production and use. It will not cause pollution to the environment during production and use. The waterproof coating significantly improves the paper's waterproof performance, making it less susceptible to water penetration when in contact with water or in a humid environment. It can maintain the integrity of the paper and the stability of its internal structure, making it widely applicable to packaging, outdoor printing and other scenarios that require waterproofing.

[0015] 3. This multi-layer thickened water-based coated paper features a tear-resistant line structure with perpendicular top and bottom edges on the base layer. This structure reinforces the paper from different directions, effectively resisting external tearing forces in all directions. This greatly enhances the overall tear resistance of the paper and improves its mechanical properties. The filler adhesive fills the gaps and micropores in the tear-resistant lines, making the tear-resistant line structure more compact and enhancing its strength and stability, further improving the paper's tear resistance.

[0016] 4. This multi-layer thickened water-based coated paper, with its excellent adhesive properties of water-based acrylic emulsion, firmly connects the base layer and the tear-resistant lines together, ensuring that the two work together to improve the physical properties of the paper.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings.

[0023] Reference Figures 1-3A multi-layer thickened water-based coated paper includes a base layer 1, which serves as the basic support structure of the paper, providing basic strength and toughness. Tear-resistant lines 2 effectively enhance the paper's tear resistance under external pulling force, improving its durability and reducing damage caused by tearing. Multiple tear-resistant lines 2 are connected to the top and bottom of the base layer 1, and a water-based coating 3 is attached to each tear-resistant line 2. The water-based coating 3 is environmentally friendly and pollution-free, conforming to modern green production and usage concepts. Simultaneously, it further protects the tear-resistant lines 2 from external environmental factors, extending their service life and ensuring the paper's tear resistance. A waterproof coating 4 is attached to the water-based coating 3, significantly improving the paper's waterproof performance. This prevents water penetration when the paper comes into contact with water or in humid environments, maintaining the paper's integrity and internal structural stability. It can be widely used in applications requiring waterproofing. In applications such as packaging and outdoor printing, the tear-resistant lines 2 located at the top and bottom of the base layer 1 are perpendicular. This vertically distributed tear-resistant line 2 structure reinforces the paper from different directions, effectively resisting external tearing forces in all directions, greatly enhancing the overall tear resistance of the paper and improving its mechanical properties. Multiple tear-resistant lines 2 are coated with filler adhesive 5, which fills the gaps and micro-holes in the tear-resistant lines 2, making the structure of the tear-resistant lines 2 more compact, enhancing their strength and stability, and thus improving the tear resistance of the paper. The base layer 1 and the multiple tear-resistant lines 2 are connected by a water-based acrylic emulsion. The water-based acrylic emulsion has excellent adhesion properties, firmly connecting the base layer 1 and the tear-resistant lines 2 together, ensuring that they work synergistically to improve the physical properties of the paper. Moreover, the water-based acrylic emulsion is also environmentally friendly and will not cause pollution to the environment.

[0024] In summary, the working principle and process of this multi-layer thickened water-based coated paper are as follows: the designed pattern is first printed onto the multi-layer thickened water-based coated paper using printing equipment. Due to the environmentally friendly characteristics of the paper, it will not cause pollution to the environment or operators during the printing process. Its waterproof performance can resist the erosion of rainwater, ensuring that the printed pattern remains clear for a long time. The all-round tear-resistant structure can resist external forces such as strong winds, ensuring the stability of the paper in outdoor environments.

[0025] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
