Problems solved by technology

[0002] With the continuous advancement of science and technology, the application of release paper is more and more widely, especially in the packaging fields of food, chemical industry, electronics, etc., but the current release paper is easily damaged by ultraviolet rays and aging due to the lack of anti-ultraviolet function. Damage will affect the damage of the packaged products. In addition, some products in the food and chemical fields are easy to be corroded by bacteria and deteriorate. Therefore, in order to expand the application field of release paper, a release paper with anti-ultraviolet Model paper urgently needs to appear

Embodiment 1

[0016] Embodiment 1: Preparation of anti-ultraviolet and antibacterial release paper

[0017] Coat one or both sides of the base paper of the release paper with a coating layer, and then coat a layer of release layer on the surface of the coating layer, and perform super calendering on it after coating the release layer. The specific steps of super calendering are as follows: : After the base paper of the release paper coated with the film layer is heated at 200°C for bridging, heated and melted at 320°C, then extruded with a pressure of 6Mpa, and then coated with a layer of antibacterial agent on the surface of the release layer Obtain an antibacterial layer, coat a layer of PET film on the surface of the antibacterial layer, and dry it at 20°C to obtain an anti-ultraviolet antibacterial release paper. The PET film layer is made of the following raw materials: 100 parts of PET chips, 25 parts of modified rosin resin, 10 parts of VAE emulsion, and 2 parts of additives. The pre...

Embodiment 2

[0019] Coat one or both sides of the base paper of the release paper with a coating layer, and then coat a layer of release layer on the surface of the coating layer, and perform super calendering on it after coating the release layer. The specific steps of super calendering are as follows: : After the base paper of the release paper coated with the film layer is heated at 230°C for bridging, heated and melted at 350°C, extruded with a pressure of 15Mpa, and then coated with a layer of antibacterial agent on the surface of the release layer Obtain an antibacterial layer, coat a layer of PET film on the surface of the antibacterial layer, and dry it at 25°C to obtain an anti-ultraviolet antibacterial release paper. The PET film layer is made of the following raw materials: 150 parts of PET chips, 30 parts of modified rosin resin, 20 parts of VAE emulsion, and 10 parts of additives. The preparation method of the PET film layer is the same as that of the ordinary PET film layer. ...

Embodiment 3

[0021] Coat one or both sides of the base paper of the release paper with a coating layer, and then coat a layer of release layer on the surface of the coating layer, and perform super calendering on it after coating the release layer. The specific steps of super calendering are as follows: : After the release paper base paper coated with the film layer is heated at 220°C for bridging, heated and melted at 330°C, extruded with a pressure of 10Mpa, and then coated with a layer of antibacterial agent on the surface of the release layer Obtain an antibacterial layer, coat a layer of PET film on the surface of the antibacterial layer, and dry it at 23°C to obtain an anti-ultraviolet antibacterial release paper. The PET film layer is made of the following raw materials: 125 parts of PET chips, 27 parts of modified rosin resin, 15 parts of VAE emulsion, and 6 parts of additives. The preparation method of the PET film layer is the same as that of the ordinary PET film layer. Modified...

Abstract

The invention discloses a preparation method of an uvioresistant antibacterial release paper. The method comprises the following steps of coating one side or two sides of base paper of the release paper with a film coating layer; coating the surface of the film coating layer with a release layer; performing super press polishing on the coated release layer; coating the surface of the release layer with an antibacterial agent to obtain an antibacterial layer; coating the surface of the antibacterial layer with a polyethylene glycol terephthalate (PET) film layer; airing the antibacterial layer at the temperature of 20-25 DEG C to obtain the uvioresistant antibacterial release paper. The release paper having an uvioresistant and antibacterial function can resist tearing; by adding vinyl acetate-ethylene (VAE) emulsion, the release paper has functions of high flexibility, acid-base resistance property, ultraviolet ageing resistance and the like; meanwhile, due to the addition of organic antibacterial agents, the release paper has extremely high antibacterial effect and can be widely used in the field of chemical engineering packaging.

Description

technical field [0001] The invention belongs to the technical field of release paper preparation, and in particular relates to an anti-ultraviolet and antibacterial release paper and a preparation method thereof. Background technique [0002] With the continuous advancement of science and technology, the application of release paper is more and more widely, especially in the packaging fields of food, chemical industry, electronics, etc., but the current release paper is easily damaged by ultraviolet rays and aging due to the lack of anti-ultraviolet function. Damage will affect the damage of the packaged products. In addition, some products in the food and chemical fields are easy to be corroded by bacteria and deteriorate. Therefore, in order to expand the application field of release paper, a release paper with anti-ultraviolet Pattern paper urgently needs to appear. Contents of the invention [0003] Purpose of the invention: Aiming at the deficiencies in the prior art...
