Problems solved by technology

[0006] 1. The average particle size (APS) of the first and second types of calcium carbonate particles in this patent case is 0.4 and 0.5 microns respectively, so the stone must go through a special grinding process, and the cost of mechanical equipment is high, resulting in a relatively large increase in manufacturing costs , because the cost price is higher than that of ordinary paper, the economic value of the existing structure is not high, so it cannot be mass-produced effectively and popularized
[0007] 2. The technology in this patent case is simply mixed with inorganic materials with high polymer and particle size. The paper produced is heavy and too soft due to the inorganic materials, and the paper quality cannot be close to that of ordinary wood pulp paper. There are still many inconveniences in use. missing, so it cannot be popularized in large numbers
[0008] 3. The technology of this patent case does not add foaming agent. Therefore, the environmentally friendly paper produced by this method cannot reduce weight and cost, so that it cannot be used as shipping filling paper, packaging paper, corrugated paper or Carton etc.
[0009] 4. The technology of this patent case does not add fireproof materials, therefore, the environmentally friendly paper produced by this method does not have fireproof function
[0011] 1. The average particle size

Example Embodiment

[0060] Example 1

[0061] see figure 1 and Figure 7 As shown, the present invention is a specific embodiment to achieve the aforementioned first object, the environmental protection paper 10 is made by mixing the first material formula and using the calendering technology, and the paper thickness of the finished environmental protection paper 10 is between 50-700 μm between. The first material formula includes a polymer material 1a and an inorganic material 1b, wherein the polymer material 1a accounts for 15-25% by weight, the inorganic material 1b accounts for 75-85% by weight, and the average particle size of the inorganic material 1b is between 1 μm ~5μm, and a finished product of the environmental protection paper 10 with a smooth surface can be obtained. A specific example of the polymer material 1a may be at least one plastic material among polypropylene (PP), polyethylene (PE) or polylactic acid (PLA), which is non-toxic and has decomposable properties.

Abstract

The invention relates to green and environmental protection paper and its manufacturing method. The green and environmental protection paper is prepared by mixing according to a formula composed of 15-25 wt% of a high polymer material and 75-85 wt% of an inorganic material. And the inorganic material has an average particle size ranging from 1 to 5 micrometers. The manufacturing method consists of: feeding mixing based on the formula, rolling and agglutination, calendaring, and cooling as well as shaping, thus obtaining the environmental protection paper. The method provided in the invention not only improves the feasibility of green and environmental protection paper, and also can make feature improvement to paper further so as to make the environmental protection paper have various functional properties and meet different use or application requirements, thereby achieving the effective environmental protection purposes of reducing the manufacturing cost of environmental protection paper, recycling waste and broadening the application range of environmental protection paper, etc.

Description

technical field [0001] The invention relates to a kind of green environment-friendly paper and its manufacturing method, in particular to a technology of using special formula materials composed of polymer materials and inorganic materials, and then mixing them into environment-friendly paper. Background technique [0002] According to current knowledge, four tons of wood chips are required to produce one ton of pulp, which is equivalent to cutting down about 23 trees. Due to the huge increase in demand for pulp, deforestation is very common, which has caused forests everywhere The area gradually shrinks. A large number of deforestation will not only affect the balance of natural ecology, but also one of the culprits of global warming. In addition, the traditional pulp papermaking method must use a large amount of water and chemicals to bleach the wood pulp, resulting in the pollution of precious water resources such as rivers and oceans. Develop alternatives to pulp. [...
