Description

Environmentally friendly inorganic paper manufacturing method

The invention relates to a method for manufacturing an environmentally friendly inorganic paper, in particular to a composition of the paper comprising more than 51% not more than 75% inorganic glass powder, 25% to 40% by weight of a viscose material; including (polypropylene (PP) (: polylactic acid (PLA) or polypropylene (PP), polyethylene (PE) mixture) and 1% to 5% by weight of additives, the process of which is mainly by continuous calendering, so that the paper produced is discarded In addition to recycling, in the case of burning, only the polypropylene with less ingredients, no high temperature and black smoke and no toxic gas, and the residue of inorganic glass powder containing more components after burning, Will return to the earth and return to nature.

According to the use of paper in countries all over the world, almost all of them are in millions of tons. In addition to the pulp supplier---trees, related waste paper supplies, and subsequent environmental protection issues, paper does occupy a very high environmental protection. Processing costs; therefore, under the limited earth resources and the number of trees restricted, the market for synthetic paper is undoubtedly an important issue to solve this problem; at the same time, it can be significantly affected by the amount of carbon released from the ring and the pollution of the surrounding area. Breakthrough and resolution.

Regarding the current international, it has indeed developed a variety of synthetic papers, in which polypropylene is the main component, and a small amount of mineral powder or combination of stone powder is added, and then implemented in a single layer or multi-layer structure; It is made of traditional plastic film products and is co-extruded in a single layer or multiple layers in the process. The forming die is made into a sheet by a die-shaped die structure, and the two sides of the sheet are stretched through the longitudinal direction, and then The sheet or the laminating sheet is bonded and then stretched in the transverse direction; the intermediate layer of the synthetic paper produced has a bidirectional extension, and the surface layer has a uniaxial stretching, thereby forming a composite paper structure of a multilayer structure.

The longitudinally stretched sheet is directly stretched in the transverse direction, and the surface of the single or multi-layer synthetic paper produced has a bidirectional extension property, and the synthetic paper prepared above has advantages, but Compared with the performance of wood pulp paper, the difference is still very large. The disadvantages of the conventional synthetic paper are as follows: poor folding, too much lateral or longitudinal tearing or no tearing, etc.; Polypropylene plastic is the main material made of synthetic paper. After use, it can be discarded or buried. It can't be oxidized and decomposed in a natural environment in a short time. It can't achieve the ability to eliminate secondary pollution. The cost of paper is also much higher than that of wood pulp. Based on the above shortcomings, various synthetic papers have not been favored by consumers until now and are widely used in the market.

In view of the problems of the prior art, the present invention provides a method for manufacturing an environmentally-friendly inorganic paper, which utilizes inorganic glass powder to solve the problem that the entire use of polypropylene plastic as the main material, and the synthetic paper obtained can not be natural in a short time. The oxidative decomposition of the environment failed to meet the requirement of reducing secondary pollution; and the cost of the synthetic paper produced was much higher than that of the wood pulp paper, which was inconsistent with the cost of use and economic considerations.
