Problems solved by technology

[0004] Although the leather release paper is easy to use, the current release paper is generally broken, mainly because the release paper has to go through the test of high temperature for many times. Under the high temperature environment, the paper is in a dry state, and the mechanical strength decreases. Coupled with the wear and tear during repeated use, it is easy to cause the release paper to break

Embodiment

[0050] see Figure 1-9 , a high-strength leather release liner treatment process, see Figure 2-3 and Figure 9 , including the following processing steps:

[0051] S1, firstly emboss the release paper with an embossing roller, pay attention to the downward pressure of the pressure roller during embossing, so as not to crush the release paper, and then conduct random inspection on the release paper after embossing to improve the qualified rate of the product;

[0052] In step S1, before embossing, the release paper is pretreated with paper wool. The method of paper wool pretreatment includes the following steps:

[0053] S11, first perform electrostatic treatment on the release paper, and then place the side to be embossed on the release paper facing down;

[0054] S12, an electric field is applied under the release paper to attract the paper hairs, and then the singeing gun is used to move back and forth quickly at an appropriate distance below the release paper to remove ...

Abstract

The invention discloses a high-strength leather release paper treatment process, which belongs to the field of leather release paper. On the basis of the existing technology, the embossing method is changed and the embossing is injected into the embossing to improve the strength of the release paper. Reinforcing material to reduce the occurrence of fragmentation, on the one hand: the embossing spans the width of the release paper, and the coverage area increases while the number of embossing is reduced, which effectively improves the horizontal tearing and longitudinal tearing of the release paper Tensile strength; on the other hand: the embossing is connected to each other, after the strength enhancing material is injected into the embossing, multiple embossings are connected in series, which effectively improves the mechanical strength of the release paper, and the heat resistance of the strength enhancing material Excellent performance and tear resistance, which can effectively reduce the breakage rate of the release paper. In addition, optional reinforcements can be added to the embossing to further increase the strength of the release paper.

Description

technical field [0001] The invention relates to the field of leather release paper, and more particularly, to a process for processing high-strength leather release paper. Background technique [0002] Release paper is a kind of release paper that prevents the prepreg from sticking and protects the prepreg from contamination. The release paper is made of paper coated with anti-sticking substances, and its model should be distinguished according to the difference in material, thickness, elongation, and single and double sides. The release paper should meet the following requirements: it can stick to the prepreg, but it is easy to separate the two; it does not chemically react with the resin system or pollute the resin system; when the ambient temperature and humidity change, the length and width of the release paper should be Keep it unchanged, so as not to cause the release paper to wrinkle and wrinkle the prepreg; it should be dense enough to prevent moisture from entering...
