Abstract
The invention belongs to the technical field of release paper, and particularly relates to environment-friendly wear-resistant water-based release paper containing organic modified montmorillonite. According to the environment-friendly wear-resistant water-based release paper containing the organic modified montmorillonite, the release paper layer is made of the breathable material, Chinese herbal medicine residues and the like are used as raw materials, the raw materials are wide in source, waste is turned into wealth, the breakdown strength and the wear resistance of the release paper are remarkably improved by adding the organic modified montmorillonite, and the surface insulation performance and the antibacterial performance of the release paper are also improved; the environment-friendly, non-toxic and pollution-free water-based release agent with low cost is adopted in the release agent layer, and distilled water is used as a dispersing agent, so that the pollution of the residual solvent to the environment and the harm to human bodies are avoided, the wear resistance of the release agent is improved due to the addition of the nano calcium carbonate, and the cost is greatly reduced; the polyethylene wax particles improve the surface lubricating property and the wear resistance of the release film, and the preparation method is simple and scientific, environment-friendly, pollution-free and low in cost.
Description
Technical Field
The invention belongs to the technical field of release paper, and particularly relates to wear-resistant water-based release paper containing organic modified montmorillonite.
Background
Release paper, also known as release paper, silicone oil paper, is a release paper that prevents prepreg from sticking and also protects prepreg from contamination, and is made by coating an anti-stick substance on a base paper, which is generally grease-proof paper, and the anti-stick substance is generally silicone oil.
The conventional release paper mainly comprises a film layer and a release agent layer coated on the film layer, wherein the release agent layer plays an important role in the release force (strippability and peel strength) of the release paper. The existing release agent layer can be roughly divided into three types of solvent type, emulsion type and solvent-free type. The solvent type is convenient to use and good in aging resistance, but the cost is high, and a large amount of residual solvent has great pollution to the environment and is harmful to the health of human bodies; compared with a solvent type, the emulsion type has the characteristics of simple coating method, safe use, low cost, good compatibility and the like, but also has some defects, such as low peel strength, low tensile property and the like; the solvent-free type coating machine has high cost, can be only used on a special coating machine, and has limited application. Meanwhile, the release agent of the existing release paper is easy to wear in the using process, so that the surface release effect is poor.
Disclosure of Invention
The purpose of the invention is as follows: in order to overcome the problems, the invention aims to provide the wear-resistant water-based release paper containing the organic modified montmorillonite.
The technical scheme is as follows: the invention aims to provide wear-resistant water-based release paper containing organic modified montmorillonite, which comprises a release paper layer, a laminating layer and a release agent layer, wherein the release paper layer is breathable release paper, and the breathable release paper comprises the following components in parts by weight: 30-40 parts of Chinese herbal medicine residues, 60-80 parts of sulfate softwood pulp, 5-25 parts of hardwood pulp, 10-30 parts of organic modified montmorillonite, 8-16 parts of bamboo fiber, 2-10 parts of lignin and 10-20 parts of nano silicon dioxide; the laminating layer is coated on the release paper layer; the release agent layer is wear-resistant water-based release agent and is uniformly coated on the laminating layer.
Preferably, the Chinese herbal medicine residues are 20-30% of the Chinese herbal medicine residues by mass, are soaked in 1-3% of NaCl solution for 12-16h, and are dried and crushed to 100-200 meshes.
Preferably, the organic modified montmorillonite is levofloxacin hydrochloride modified montmorillonite.
