Problems solved by technology

[0006] It can be seen that mineral fiber plays an important role in improving the performance of stone paper in the preparation process of stone paper. However, in the existing technology of making stone paper from mineral fiber, mineral fiber is generally used as the filler of paper, that is, It is said that some mineral fibers are contained in the raw materials for the preparation of stone paper, and there is no stone paper preparation technology that can fully use mineral fibers as raw materials and give full play to the advantages of mineral fibers in the preparation process of stone paper

Embodiment 1

[0033] Put the sepiolite fiber powder raw material into the flotation tank with water at a rate of less than or equal to 300kg / h for cleaning to remove foreign impurities in the sepiolite fiber powder, and obtain clean sepiolite fiber powder after drying Raw materials, then, sepiolite fiber powder is sieved to obtain sepiolite fiber powder A with a particle size of 10 μm and a length of 200 μm, and sepiolite fiber powder B with a particle size of 1 μm and a length of 50 μm. The sepiolite fiber powder B is activated. Specifically, the sepiolite fiber powder B of 95% by weight and the titanate of 5% by weight are added to the powder surface modification machine, and the activation is set. The temperature is 50° C., the feed rate is 500 kg / h, and the rotation speed is 1000 rpm. Next, take 15% by weight of sepiolite fiber powder A and put it into the pulp mixing box 1, use 50°C water to prepare a coarse pulp with a mass concentration of 1.7%, and take the activated weight percenta...

Embodiment 3

[0041] Select the cleaned brucite fiber powder and sieve to obtain brucite fiber powder A with a particle size of 15 μm and a length of 250 μm, and sepiolite fiber powder B with a particle size of 8 μm and a length of 150 μm. Fiber powder B is activated. Specifically, brucite fiber powder B with a weight percentage of 97% and stearic acid with a weight percentage of 3% are added to the powder surface modifier, and the activation temperature is set to 50 °C, the feed rate is 600kg / h, and the rotation speed is 1200rpm. Next, take brucite fiber powder A with a weight percentage of 25% and put it into the pulp mixing box 1, use 50°C water to prepare a coarse slurry with a mass concentration of 1.2%, and take the activated weight percentage of 75% brucite fiber powder A The stone fiber powder B is put into the pulp mixing box 2 different from the pulp mixing box 1, and the water at 50°C is used to make a fine slurry with a mass concentration of 0.6%, and ethylene acetate with a wei...

Abstract

The invention discloses a method for manufacturing stone paper from mineral fibers. The method has the advantages that fine pulp and coarse pulp can be respectively prepared from mineral fiber powder by means of size separation, water-based adhesive is added into the fine pulp, papermaking means are carried out by the aid of the fine pulp and the coarse pulp, the adhesive can be sufficiently coated owing to the small particle size of the mineral fiber powder in the fine pulp, accordingly, the contact areas of coarse fibers and the water-based adhesive can be increased when fine mineral fiber powder and coarse mineral fiber powder are in contact with each other, the toughness of the paper can be improved, and the tensile, heat-insulation and insulating stone paper can be manufactured.

Description

technical field [0001] The invention relates to the field of stone paper, in particular to a method for preparing stone paper from mineral fibers. Background technique [0002] Rich Mineral Paper (RMP) is also called Rich Mineral Paper. It uses the most abundant mineral resources in the earth's crust as the main raw material, uses polymer materials and various inorganic substances as auxiliary materials, and utilizes the principles of polymer interface chemistry and filling modification technology. The prepared paper is waterproof and not easy to burn, tear-resistant and fold-resistant. The stone paper papermaking technology does not require cooking, washing, bleaching and other processes in the traditional papermaking process in the entire production process, and does not need to add strong acid and strong alkali. , bleaching powder and many other organic chlorides, so it not only solves the problem of harm to the environment caused by traditional papermaking pollution, but...
