Problems solved by technology

[0006] There are three main production methods for the transparent paper prepared by the above patents and the prior art: filtration, extrusion molding and dipping. The transparency of the paper products produced by it is generally less than 80%, and the surface roughness of the paper is relatively high, which cannot meet the requirements such as The requirements of electronic devices and other fields limit the application range of transparent paper

Embodiment 1

[0018] A method for preparing high-transparency transparent paper using bismuth-containing materials, the preparation technical scheme is as follows:

[0019] According to the number of parts by mass, disperse 1.3 parts of wood pulp fibers in 120 parts of deionized water, then add 60 parts of bismuth-containing nanocellulose suspension, stir evenly and ultrasonically disperse for 25 minutes to form a suspension for later use; then take another 30 parts of bismuth-containing nanocellulose suspensions are filtered using a microporous membrane to form a nanocellulose layer; then the suspension is continued to be filtered on the microporous membrane to form a cellulose layer; the cellulose layer Peel it off from the microporous filter membrane, use a clean and flat mold to put it into a hot press at 60°C for 40 minutes, then turn off the heating system of the hot press, and cool it under pressure to obtain the described A highly transparent transparent paper using bismuth-containi...

Embodiment 2

[0027] A method for preparing high-transparency transparent paper using bismuth-containing materials, the preparation technical scheme is as follows:

[0028] According to the number of parts by mass, disperse 0.5 parts of wood pulp fibers in 80 parts of deionized water, then add 50 parts of bismuth-containing nanocellulose suspension, stir evenly and ultrasonically disperse for 20 minutes to form a suspension for later use; then take another 20 parts of bismuth-containing nanocellulose suspensions are filtered using a microporous membrane to form a nanocellulose layer; then the suspension is continued to be filtered on the microporous membrane to form a cellulose layer; the cellulose layer Peel it off from the microporous filter membrane, use a clean and flat mold to put it into a hot press at 50°C for 30 minutes, then turn off the heating system of the hot press, and cool it under pressure to obtain the described A highly transparent transparent paper using bismuth-containin...

Embodiment 3

[0036] A method for preparing high-transparency transparent paper using bismuth-containing materials, the preparation technical scheme is as follows:

[0037] According to the number of parts by mass, disperse 2 parts of wood pulp fibers in 150 parts of deionized water, then add 80 parts of bismuth-containing nanocellulose suspension, stir evenly and ultrasonically disperse for 30 minutes to form a suspension for later use; then take another 40 parts of bismuth-containing nanocellulose suspensions are filtered using a microporous membrane to form a nanocellulose layer; then the suspension is continued to be filtered on the microporous membrane to form a cellulose layer; the cellulose layer Peel it off from the microporous filter membrane, use a clean and flat mold to put it into a hot press at 70°C for 60 minutes, then turn off the heating system of the hot press, and cool it under pressure to obtain the described A highly transparent transparent paper using bismuth-containing...

Abstract

The invention belongs to the field of paper making new material, and more specifically relates to a preparation method of high transparency cellophane paper prepared from a bismuth containing material. According to the preparation method, a bismuth containing nanometer fiber suspension solution is prepared, and is used for filling the porous structure of wood fiber networks, so that light transmittance is increased; and hot pressing is adopted so as to obtain the high transparency cellophane paper prepared from the bismuth containing material. The high transparency cellophane paper is excellent in optical performance and surface roughness, the writing performance of conventional paper is maintained, the high transparency cellophane paper can be used for preparation of hand drawing conductive circuit devices, the morphological stability is high, and subsequent aqueous coating requirements can be satisfied.

Description

technical field [0001] The invention relates to the field of material preparation, in particular to a method for preparing high-transparency transparent paper using bismuth-containing materials. Background technique [0002] Transparent paper is a kind of special paper. Because of its excellent optical properties and beautiful visual effects, it is widely used in labels, decoration, food packaging, insulation and other fields. It is more likely to replace plastic films to prepare the next generation of "green" electronic devices; Its advantages of light weight and low cost are also excellent materials for light-transmitting buildings and solar cells. [0003] CN106917311A discloses a preparation method of transparent paper, which belongs to nano / micro microstructure materials and preparation technology thereof. The transparent paper referred to in the invention refers to a fibrous material composed of nanometer and micrometer wood fiber materials with a transparency greater...
