Problems solved by technology

[0004] The shell of the high-frequency deflaking machine produced by the original Shanghai Light Machinery No. 2 Factory is selected, but the inner moving plate and fixed ring gear are redesigned and processed, because the beating degree of the original high-frequency deflaking machine will increase by 3-5 degrees, and at the same time The wet weight drops by 0.5-1 gram, indicating that it has a certain broom shape, which is not conducive to the quality requirements of ecological paper
[0005] At present, there is a lack of a kind of environmentally friendly ecological paper with loose structure, good flatness and high water absorption and its preparation method

Embodiment 1

[0031] In order to improve the tensile strength of the finished paper and the water absorption performance of the paper, the beating is to keep the length of the fiber as much as possible, and the fiber bundles can be simply dispersed without damaging the fibers. For the above beating requirements, through several improvements in the processing performance of the beating equipment, the ring gear produced can not only disperse and loosen the pulp fiber bundles, but also keep the beating degree and wet weight of the pulp unchanged.

[0032] The high-frequency deflaking machine produced by the original Shanghai Light Machinery No. The weight decreased by 0.5-1 gram, indicating that it has a certain broom shape, which is not conducive to the quality requirements of ecological paper. After the newly designed and processed beating ring gear is used, there is almost no change in the beating degree and wet weight of the pulp after testing. The fiber bundles are completely disentangled...

Embodiment 2

[0048] The difference between embodiment 2 and embodiment 1 is:

[0049] A kind of environment-friendly ecological paper of the present invention comprises the following components in mass percentage:

[0050] Bleached Softwood Pulp 20%,

[0051] Chemimechanical wood pulp 40%,

[0052] Poplar Machine Wood Flour 30%,

[0053] 10% polyester.

[0054] The thickness of the environment-friendly ecological paper is 42 filaments.

[0055] The preparation method of environment-friendly type ecological paper of the present invention, comprises the steps:

[0056]In step (2), the bleached softwood pulp is put into the high-consistency pulper and then crushed, then enters the second crushing tank, and then enters the softwood pulp tank. The bleached softwood pulp with longer fibers is separately beaten by double disc mills Separation and broomification, enter the needle pulp tank; the degree of percussion of bleached softwood pulp is 25°SR, and the wet weight is controlled at 10g. ...

Embodiment 3

[0061] The difference between embodiment 3 and embodiment 1 is:

[0062] A kind of environment-friendly ecological paper of the present invention comprises the following components in mass percentage:

[0063] Bleached Softwood Pulp 18%,

[0064] Chemimechanical wood pulp 40%,

[0065] Poplar Machine Wood Flour 32%,

[0066] 10% polyester.

[0067] The thickness of the environment-friendly ecological paper is 38 silk.

[0068] The preparation method of environment-friendly type ecological paper of the present invention, comprises the steps:

[0069] In step (2), the bleached softwood pulp is put into the high-consistency pulper and then crushed, then enters the second crushing tank, and then enters the softwood pulp tank. The bleached softwood pulp with longer fibers is separately beaten by double disc mills Separation and broomification, enter the needle pulp tank; the degree of percussion of bleached softwood pulp is 23°SR, and the wet weight is controlled at 8g.

Abstract

The invention discloses an environmentally-friendly ecologic paper and a making method thereof. The environmentally-friendly ecologic paper comprises, by mass, 15-20% of bleached softwood pulp, 40% of chemi-mechanical wood pulp, 30-35% of poplar wood powder and 10% of polyester fibers. The finished paper has the advantages of loose structure, high water absorption rate, great reduction of the production cost, high surface flatness (smooth paper surface), increase of the interweaving force among fibers, improvement of the bonding force of the fibers, and enhanced tensile strength.

Description

technical field [0001] The invention relates to the technical field of paper preparation, in particular to an environment-friendly ecological paper and a preparation method thereof. Background technique [0002] Blockboard, which is plywood with a core of solid wood. Compared with side flower board and medium density fiberboard, the natural wood characteristics of blockboard are more in line with the requirements of human beings for natural ecology. It has the advantages of light weight, easy processing, good nail holding power, and no deformation. It is an ideal choice for interior decoration and high-end It is an ideal material for furniture making, mainly used in furniture manufacturing, door panels, wall panels, etc. It is made of two veneers glued together in the middle. [0003] Ecological paper is mainly used for the two surfaces of the blockboard to replace the surface technology wood. The ecological base paper is impregnated and then hot-pressed on both sides of t...
