Problems solved by technology

[0003] When the release paper is used as a release paper in conjunction with sticky materials, the quality requirements for the release paper are to ensure its stability and peelability, so as to avoid direct damage or damage to the sticky material due to quality problems of the release paper , which in turn affects the action of viscous materials
[0004] When the existing release paper is used in conjunction with viscous materials, in order to ensure its quality and service life, its storage environment is required to maintain a temperature of 22±2°C and a relative humidity of 50%±5%. In the process of storage and transportation, such strict environmental requirements cannot be effectively maintained. After the release paper is subjected to changes in humidity and temperature, the fiber deformation will cause air bubbles or silicone oil reverse seepage, which will make the viscous materials used with it Cause damage, reduce its peeling degree and affect the viscosity of viscous materials, thereby affecting the performance of release paper

Embodiment 1

[0067] see figure 1 , image 3 , Figure 5 , Figure 6 and Figure 10 , a preparation process of glue-fixing and moisturizing type release paper, comprising the steps of:

[0068] S1. Raw material preparation: The pre-prepared hydrophobic air-permeable air cells 21 are condensed into a film through the interaction of the temperature-insulating implicated branches 22, and the glue-fixed moisturizing film 2 is obtained;

[0069] S2. Coating: Select a suitable type of stable substrate paper 1 according to the preparation specifications, and use a laminating machine to coat a layer of isolation coating 3 on the upper end of the stable substrate paper 1;

[0070] S3 solid film: apply a layer of adhesive glue on the upper side of the stable base paper 1 with the isolation type coating 3 through glue coating equipment, and then lay the solid glue moisturizing film 2 on the top of the isolation type coating 3 Bond the upper side of the glue, and then complete the bonding and fixi...

Embodiment 2

[0084] see figure 2 , Figure 4-6 and Figure 10 , where the same or corresponding components as those in Embodiment 1 use the corresponding reference numerals as in Embodiment 1, and for the sake of simplicity, only the differences from Embodiment 1 will be described below. The difference between this embodiment 2 and embodiment 1 is: please refer to figure 2 and Figure 4 , a preparation process of glue-fixing and moisturizing type release paper, comprising the steps of:

[0085] M1. Raw material preparation: The pre-prepared hydrophobic air-retaining air cells 21 are condensed into a film through the interaction of the temperature-insulating implicated branches 22, and the glue-fixed moisturizing film 2 is obtained;

[0086] M2 solid film: select a suitable type of stable base paper 1 according to the preparation specifications, use glue coating equipment to coat a layer of adhesive on the upper end of the stable base paper 1, and then lay the solid glue moisturizing ...

Embodiment 3

[0101] see Figure 6-9 and Figure 11 , wherein the same or corresponding components as those in Embodiment 1 or 2 use the corresponding reference numerals as in Embodiment 1 or 2, and for the sake of simplicity, only the differences from Embodiment 1 or 2 are described below. The difference between this embodiment 3 and embodiment 1 or 2 is:

[0102] see Figure 6 and Figure 7 The hydrophobic air-retaining bubble 21 is provided with a temperature-sensing retaining component 6 matched with uniform temperature condensation hydrophobic particles 2102. The temperature-sensing maintaining component 6 includes a star-shaped temperature-conducting support 601, and the hydrophobic retaining air-permeable bubble 21 is fixedly connected in the center Star-shaped temperature-conducting support 601, the outer end of the star-shaped temperature-conducting support 601 is fixedly connected with a uniform temperature condensation ring 602, and the outer end of the uniform temperature con...

Abstract

The invention discloses a preparation process of glue fixing and moisturizing type release paper, and belongs to the field of release papers.The preparation process of the glue fixing and moisturizing type release paper comprises the following steps: preparing raw materials ; spraying a film; fixing the film; coating a film; performing drying and edge sealing; and performing quality inspection warehousing; before film coating in the preparation process of the moisturizing type release paper body, a solid glue moisturizing film can be added into the moisturizing type release paper body, when the moisturizing type release paper body is stimulated by the temperature and humidity of the storage environment, the humidity and temperature balance of the moisturizing type release paper body are effectively kept, and the change amplitude of the temperature and humidity is reduced; furthermore, the stability of a stripping silicone oil film connected with the viscous material is effectively maintained, the damage of the change of the moisturizing release paper body to the viscous material is effectively reduced, the stability of the viscous material at the upper end of the moisturizing release paper body is improved, the stripping degree of the moisturizing release paper body and the viscosity of the viscous material are effectively ensured, and the use performance of the moisturizing release paper body is improved.

Description

technical field [0001] The invention relates to the field of release paper, in particular to a preparation process of a glue-fixing and moisturizing release paper. Background technique [0002] Release paper, also known as silicone oil paper and anti-adhesive paper, mainly plays the role of isolating sticky objects, such as tapes, etc., which generally need to be peeled off and discarded during use. Now the most widely used is tape Or the carrier of glued products, it is also used in the food, medical and health industries. Release paper generally has a three-layer structure: the first layer is the backing paper, the second layer is the isolation layer, and the third layer is the release agent layer. [0003] When the release paper is used as a release paper in conjunction with sticky materials, the quality requirements for the release paper are to ensure its stability and peelability, so as to avoid direct damage or damage to the sticky material due to quality problems of ...
