Embodiment 1

[0022] The embodiment of the present application shows a method for paper surface modification, such as figure 1 shown, including the following steps:

[0023] Step S01: paper fiber thinning to obtain short fibers;

[0024] It should be noted that in the prior art, when the anti-mold material is applied on the surface of the paper, the phenomenon that the anti-mold material cannot be retained due to the smooth surface of the paper often occurs, resulting in poor anti-mold effect of the paper. In the embodiments of the present application, the residence time of the anti-mold material is improved by changing the roughness of the paper surface and increasing the pores on the paper surface, and finally the anti-mold effect of the paper is improved.

[0025] Paper is made of long and short fibers overlapping each other, which gives the paper its toughness. Thining the paper fibers to obtain short fibers of a certain specification can better change the fiber structure of the paper...

Embodiment 2

[0037] Embodiment two, the difference with embodiment one is only:

[0038] Further, the step S01 includes the following steps: passing the paper fiber through a fiber pulverizer, and the pulverization time is 4-6 hours. When the crushing time is 4-6 hours, the paper fibers can be crushed to the length of the required short fibers.

[0039] Preferably, the fiber pulverizer is a wood fiber pulverizer. The wood fiber pulverizer is composed of coarse crushing, fine crushing, wind conveying and other components. The motor drives the main shaft to run at high speed, so that the mechanical energy can generate high-strength crushing for the pulverized materials. Impact force, compression force, cutting force, friction force, so it has a unique crushing function for fibrous materials.

[0040] Optionally, the fiber pulverizer is a portable high-speed pulverizer. The portable high-speed pulverizer has the advantages of simple structure, small size, light weight, high efficacy, no dust...

Abstract

The invention discloses a paper surface modification method. The paper surface modification method comprises the following steps: S01, refining paper fiber to obtain short fiber; S02, mixing and stirring the short fiber, a paper pulp, a slow release agent and a mildew preventive to obtain a modifier; S03, coating one side of a paper surface with the modifier by using a coating machine to obtain modified thin paper. By the paper surface modification method, the modifier with the short fiber is prepared, and the paper surface is coated with the modifier to roughen the paper surface and increasethe porosity of the paper surface, so that the slow release agent and the making in the modifier are retained for a longer time, and thus the anti-mildew effect of the modified thin paper is improved.

Description

technical field [0001] The present application relates to the technical field of paper surface modification, in particular to a method for paper surface modification. Background technique [0002] Mildew and corruption of by-products is the enemy that seriously affects its timeliness and quality. The main reason for the deterioration and corruption of by-products is that various molds grow and reproduce in large numbers on by-products. In the prior art, one of the important means to prevent by-products from mildew and corruption is to add anti-mold substances on their packaging, which has a certain inhibitory effect on mold. [0003] In the prior art, when the by-product wrapping paper is prepared, the anti-mold substance stays on the wrapping paper for a short period of time, and the anti-mold effect of the wrapping paper on the non-staple food is not good, resulting in the spoilage of the non-staple food in a short period of time, seriously affecting product quality. Co...
