Description

DETAILED DESCRIPTION OF THE INVENTION This invention is based on the previously filed patent application No. 86430 (non-flammable cigarettes) filed in 1972, and the process for producing the paper, patent application No. 29689 (1973) (paper manufacturing apparatus using the intake method). ) is left unattended without any collaborators, and as a result of their research, they discovered a rare raw material that is an inorganic fiber with solidifying properties, and decided to make improvements that would make use of the original invention.

The present invention will be explained in detail below with reference to the drawings.

First, I will explain the peculiarities of the main ingredient, Sepiolai I. 1 shows the molecular structure of Seviolite. ``It has a brick stacked crystal structure with many large gaps, and because the surface of the gaps has (-OH), it has strong adhesive properties and has unique properties such as thixotropy and plasticity. It has a nature.

Moreover, it has the property of solidifying when dried after absorbing water. This inorganic fiber 1 is as delicate as deerskin fiber. Therefore, in the present invention 1, which utilizes the above, Seviolite alone can produce inorganic paper. This is the structure of a practical non-combustible wallpaper in which fibers 2 or Ishikoma 13 are mixed into JKJ7J.

The third invention is a heat-resistant, chemical-resistant, water-resistant filtration method in which a heat-resistant, chemical-resistant, water-resistant filtration film is produced by mixing a small amount of a suitable solidifying agent such as silicone or Teflon. paper(
°1♂Structure.

In the fourth invention, in order to improve the non-flammability of cigarette wrapping paper, only the long fibers of sepiolyte (1) are selected as the main material, and an appropriate amount of ultra-fine glass fiber (2) is mixed in as a reinforcing material to further obtain appropriate air permeability. Therefore, the paper is made by mixing an appropriate amount of a combustible sizing agent such as PVA or CMC. The structure of nonflammable tissue paper, etc.

・In the invention with the structure described in 2, the uniqueness of the rare inorganic fiber (Seviolite) 1, (adsorptive property) (thixotropy) (-ri
This is a method for producing non-combustible paper, which is characterized by making it possible to easily produce inorganic paper, which could not be produced using conventional techniques, by using J plasticity. The second invention is a durable non-combustible wall paper made by mixing appropriate amounts of glass fibers and asbestos in the first paper manufacturing method. Since papermaking relies on the caking properties of Sepiolite 1-, it is possible to prevent the disadvantage of significant water solubility, and it has excellent water resistance, heat resistance,
The structure of filter paper is made by mixing a small amount of resin such as silicone or Teflon, which is an example of a chemical-resistant agent. In the fourth method, in order to make cigarette paper from inorganic fibers, only the long fiber portion of Sebiolye 1 to 1, which is the main raw material for making paper using the paper making method of the first invention, is selected and used alone or in extremely large amounts. Structure of non-combustible paper for cigarettes made by mixing a part of thin glass fibers 2 for reinforcement and further mixing an appropriate amount of a sizing agent such as PVA or CMC as a caking agent to form thin paper. It is.

As mentioned above, these inventions utilize the rare inorganic fibrous sepiolyte 1- and its unique adsorption properties, thixotropy,
A method for manufacturing non-combustible inorganic fiber paper that can be easily made using oak, which was previously impossible to make due to its plasticity, and a durable non-combustible wall paper made using this method, which is useful for fire prevention and heat-resistant. Chemical-resistant and water-resistant filter paper is used for special filtration, and non-flammable cigarettes prevent ash from falling off when smoking, allow continuous ventilation from the burning part, and have a mellow taste. This is an extremely effective and appropriate invention, as fires caused by discarded cigarette butts can be extinguished by natural extinguishing methods (the pungent odor of burning paper and smoke from ashes can be extremely harmful). -4-1 Brief description of aspects - The drawings show a schematic embodiment of the present invention, and Figure 1 is a theoretical explanatory diagram of rare inorganic raw materials.
