Embodiment 1

[0019] The present invention provides a heat-insulating glassine release paper manufacturing process, which includes the following steps:

[0020] S1: Select the glassine base paper as the raw material and place the glassine base paper in the cleaning device for multiple cleanings. After the cleaning is completed, it is dried by the drying device, and then placed in a sterile environment for later use;

[0021] S2: Place the glassine base paper processed in S1 on the overpressure machine again, and compress the glassine base paper under the condition of 40 degrees Celsius. During the compression process, the overpressure machine needs to be repeatedly compressed and compressed. Time is 20min;

[0022] S3: After the glassine base paper is compressed, the smoothness detection device is used to detect the surface smoothness of the glassine base paper to ensure the smoothness, gloss, tightness and uniformity of the thickness of the paper, and to improve the appearance quality of the pape...

[0032] The present invention provides a heat-insulating glassine release paper manufacturing process, which includes the following steps:

[0033] S1: Select the glassine base paper as the raw material and place the glassine base paper in the cleaning device for multiple cleanings. After the cleaning is completed, it is dried by the drying device, and then placed in a sterile environment for later use;

[0034] S2: Put the glassine base paper processed in S1 on the overpressure machine again, and compress the glassine base paper under the condition of 44 degrees Celsius. During the compression process, the overpressure machine needs to be repeatedly compressed and compressed. The time is 24min;

[0035] S3: After the glassine base paper is compressed, the smoothness detection device is used to detect the surface smoothness of the glassine base paper to ensure the smoothness, gloss, tightness and uniformity of the thickness of the paper, and to improve the appearance quality of the pa...

Embodiment 3

[0045] The present invention provides a heat-insulating glassine release paper manufacturing process, which includes the following steps:

[0046] S1: Select the glassine base paper as the raw material and place the glassine base paper in the cleaning device for multiple cleanings. After the cleaning is completed, it is dried by the drying device, and then placed in a sterile environment for later use;

[0047] S2: Put the glassine base paper treated in S1 on the overpressure machine again, and compress the glassine base paper at 48 degrees Celsius. During the compression process, the overpressure machine needs to be repeatedly compressed and compressed. The time is 28min;

[0048] S3: After the glassine base paper is compressed, the smoothness detection device is used to detect the surface smoothness of the glassine base paper to ensure the smoothness, gloss, tightness and uniformity of the thickness of the paper, and to improve the appearance quality of the paper. If it meets the ...

Abstract

The invention discloses a manufacturing technology of thermal-insulation glassine release paper. The manufacturing technology comprises the following steps of selecting glassine body paper as a raw material to be put on an overpressure machine again, compressing the glassine body paper under the condition of 40-50 DEG C, then using a smoothness detecting device to detect the surface smoothness ofthe glassine body paper, putting the glassine body paper under the condition of 70-90 DEG C, then smearing the surface of the treated glassine body paper with a thermal-insulation coating through a coating machine, smearing the surface of the coated glassine body paper with a release agent, then putting the glassine body paper under the condition of 70-90 DEG C to be dried, and immediately takingout the glassine body paper when the surface moisture of the body paper meets the requirements, so that the thermal-insulation glassine release paper is obtained. By means of the manufacturing technology of the thermal-insulation glassine release paper, thermal-insulation performance can be integrated into the release paper while original features of the release paper are guaranteed, so that the release paper has thermal-insulation performance, and the service life of the release paper is effectively prolonged.

Description

Technical field [0001] The invention relates to the technical field of release paper preparation, in particular to a heat-insulating glassine release paper production process. Background technique [0002] Release paper is also called release paper and release paper. It is a kind of anti-sticking paper that prevents the prepreg from sticking and can protect the prepreg from contamination. When the prepreg is produced by the wet method, release paper is placed above and below the prepreg, and the lower release paper is stored in the prepreg as the prepreg is wound, so the surface of the prepreg is usually protected by a layer of release paper. The function of the release paper is to prevent the prepreg from being contaminated and to provide convenience for marking on its surface. Another function of the release paper is to prevent the lateral cracking of the unidirectional prepreg. As the release paper is used more and more widely, its quality requirements are also different.
