Embodiment 1

[0031] A kind of preparation method of natural flexible transparent paper, its operation steps are:

[0032]Prepare the dissolved wood pulp into a 0.5% concentration of dissolved wood pulp, then add 20%-80% nano-cellulose suspension, stir and mix evenly, and use a paper sheet machine to copy the wood pulp into base paper. After completion, it will be made into The raw paper is placed in a drying oven at 100°C for 60 minutes, and then the silicon-containing ionic liquid transparent agent is added at a rate of 0.1g / m 2 Evenly spread the amount on the surface of the base paper, and let it stand at 40°C for 60 minutes; then heat the base paper at a temperature of 80°C, a pressure of 0.5MPa, and a time of 5 minutes. After the treatment, the base paper is washed in ethanol, and then repeated After hot pressing for 30 minutes, the natural flexible transparent paper can be obtained.

[0033] The preparation method of described nanocellulose suspension is as follows:

[0034] Add 3kg...

Embodiment 2

[0042] A kind of preparation method of natural flexible transparent paper, its operation steps are:

[0043] Prepare the dissolved wood pulp into a 2.5% concentration of dissolved wood pulp, then add 50% nano-cellulose suspension, stir and mix evenly, and use a paper hand-sheet machine to copy the wood pulp into base paper. After completion, make the base paper Place it in a drying oven at 110°C for 90 minutes, and then put the silicon-containing ionic liquid transparent agent at a rate of 0.5g / m 2 Evenly spread the amount on the surface of the base paper, and let it stand at 50°C for 70 minutes; then heat the base paper at a temperature of 100°C, a pressure of 2.5MPa, and a time of 15 minutes. After the treatment, the base paper is washed in ethanol, and then repeated After hot pressing for 40 minutes, the natural flexible transparent paper can be obtained.

[0045] Add 5kg of dissolved woo...

Embodiment 3

[0053] A kind of preparation method of natural flexible transparent paper, its operation steps are:

[0054] Prepare the dissolved wood pulp into a 5% concentration of dissolved wood pulp, then add 80% nano-cellulose suspension, stir and mix evenly, and use a paper sheet machine to copy the wood pulp into base paper. After completion, make the base paper Place in a drying oven at 120°C to dry for 120 minutes, and then put the silicon-containing ionic liquid transparent agent at a rate of 0.8g / m 2 The amount of the base paper is evenly coated on the surface of the base paper, and the base paper is placed at 60°C for 80 minutes; then the base paper is subjected to hot-pressing treatment at a temperature of 120°C, a pressure of 5MPa, and a time of 30 minutes. After the treatment, the base paper is washed in ethanol, and then repeated heating After pressing for 60 minutes, the natural flexible transparent paper can be obtained.

Abstract

The invention relates to the field of chemical industry, in particular to a method for preparing a natural flexible transparent paper; a method for preparing a natural flexible transparent paper of the present invention, in which a suspension of nano-cellulose is added to a dissolved wood pulp to form a Base paper, then dry base paper surface hot pressing is prepared into a kind of natural transparent paper, this kind of transparent paper can be used as natural flexible transparent paper and can be applied to fields such as electronic devices such as organic light-emitting diode, display screen, solar cell; The present invention Natural flexible transparent paper has the advantages of high light transparency, low thermal expansion coefficient, good printing performance, flexibility and curling, etc. The use of all-natural materials has the advantages of environmental protection, simple process, and low cost.

Description

technical field [0001] The invention relates to the field of papermaking, in particular to a method for preparing natural flexible transparent paper. Background technique [0002] Flexible transparent paper has been successfully applied in the fields of flexible organic light-emitting diodes, display screens, solar cells and other electronic devices due to its advantages of low cost, non-fragile, flexible and rollable. [0003] CN201610341731.1 discloses a kind of all-cellulose transparent paper and its preparation method. The paper or plant fiber obtained by the traditional papermaking process is used as the network skeleton, and the cellulose homogeneous solution with a certain solubility is used as the filler and the dissolution medium. On the surface of paper or plant fibers, fill the internal pores and dissolve cellulose side chains or part of the cellulose in a high-efficiency and low-cost way to reduce porosity; improve the flatness through post-finishing processes to...
