Problems solved by technology

[0006] The main problems of the above-mentioned release paper / film are: 1. Use ordinary release base paper, which is coated with polyethylene or polypropylene, and then coated with silicone; or coated with a primer before use. Silicone oil coating to achieve anti-adhesive effect and release performance
Solvent-based silicone is generally used in the industry. Although it is convenient to use, a large amount of solvent remains in the processed product, which is likely to cause environmental pollution and endanger health; 2. Coating technology, silicone oil quality, substrate conditions, coating amount and other factors directly It affects the quality of the release product, and the product quality stability is poor; 3. The surface resistance of the release paper / film coated with silicone release agent is relatively large. After friction during processing, the surface is prone to static electricity and absorbs air. 4. Most of the release paper / film manufacturers in China have problems such as uneven silicon coating, non-adjustable peeling force, and low residual adhesion rate.

Abstract

The invention discloses a disposable hygroscopic article, which comprises a liquid-permeable top layer, an absorption core body, a liquid-impermeable bottom layer and a multi-layer coextruded composite release film from top to bottom, wherein the multi-layer coextruded composite release film comprises a surface layer (1), a core layer (2) and a release layer (3). The disposable hygroscopic article is characterized in that the surface layer (1) is prepared from matting resin and polyolefin resin A; the core layer (2) is prepared from a filling material, polyolefin resin B and a thermoplastic elastomer; the release layer (3) is prepared from alpha-olefin polymer resin produced by metallocene, C4 to C14 polyolefin resin produced by a Z-N catalyst and fluorosilicon resin. The surface layer (1) of the multi-layer coextruded composite release film has the surface wetting tension not less than 38dyn / cm<2>, the surface electrical resistivity not less than 10<10>omega and the glossiness less than 15 percent; the release layer has the stripping force of 8.0gf / inch to 18gf / inch, the release residual adhesion rate not less than 90 percent and the heat bonding strength not less than 1.5N / inch. Compared with the prior art, the multi-layer coextruded composite release film has matting, antistatic and release anti-adhesion effects; further, the viscosity loss or the adhesive transfer of a back adhesive of a hygienic article can be effectively prevented.

Description

technical field [0001] The invention relates to a disposable hygroscopic article, in particular to a disposable hygroscopic article containing a multi-layer co-extruded composite release film that can replace the traditional release paper / film.
