Problems solved by technology

[0002] The traditional decorative paper needs to be used in the downstream of the industrial chain. When the decorative paper is prepared, the decorative base paper is impregnated with a large amount of urea-formaldehyde glue and melamine-formaldehyde resin to make the decorative paper waterproof, anti-fouling and increase the strength. The facing paper will always release formaldehyde, which has health and safety hazards and is not environmentally friendly
The traditional facing paper made by the above method is hard and cannot be curled, and can only be cut into flat sheets for use, which severely limits its application range and increases transportation and storage costs; and can only be hot-pressed and flat-bonded to wood-based panels The surface cannot be covered with curved or irregular-shaped boards; at the same time, because the lamination method of the veneer paper is hot-pressed flat, the speed is slow, the energy consumption is high, and the efficiency is low; in addition, when the traditional veneer paper is used, additional construction is required Factory building and installation equipment, while controlling urea-formaldehyde glue and melamine-formaldehyde resin soaking and its own weight, the input cost of raw materials and equipment is very high

Embodiment 1

[0029] Prepare raw material plant fiber, inorganic fiber, sepiolite, EVA resin and modifier; the preparation method of modifier is: add pulping black liquor to sodium dodecylbenzene sulfonate, stir for 20-30 minutes, and then Add sodium silicate, silver-loaded zeolite powder and powdered activated carbon, and continue stirring for 30-40 minutes to make a modifier;

[0030] Plant fibers are crop straw, poplar, bagasse, pulp or forestry processing residues;

[0031] Inorganic fiber is glass fiber and ore powder;

[0032] According to the mass percentage of raw materials, plant fiber accounts for 60%, glass fiber accounts for 10%, ore powder accounts for 10%, sepiolite accounts for 5%, EVA resin accounts for 5%, and modifier accounts for 10%;

[0033] Stir the plant fiber with water, then add inorganic fiber, sepiolite, EVA resin and modifier, and stir evenly to obtain a mixed material; the amount of water added is 1:5 according to the mass ratio of plant fiber to water;

[003...

Embodiment 2

[0037] Method is with embodiment 1, and difference is:

[0038] (1) Inorganic fiber is ore powder; plant fiber is crop straw, poplar, bagasse, pulp or forestry processing residue;

[0039] (2) plant fiber accounts for 65% by mass percentage in the raw material, ore powder accounts for 15%, sepiolite accounts for 10%, EVA resin accounts for 5%, modifier accounts for 5%;

[0040] (3) The addition of water is 1: 10 by the mass ratio of plant fiber and water;

[0041] (4) The pressure of pressing and dehydration is 400KN / m; the temperature of drying and dehydration is 120°C.

Embodiment 3

[0043] Method is with embodiment 1, and difference is:

[0044] (1) Inorganic fibers are glass fibers; plant fibers are crop straw, poplar, bagasse, pulp or forestry processing residues;

[0045] (1) plant fiber accounts for 70% by mass percentage in the raw material, glass fiber accounts for 10%, sepiolite accounts for 5%, EVA resin accounts for 5%, modifier accounts for 15%;

[0046] (2) the addition of water is 1: 8 by the mass ratio of plant fiber and water;

[0047] (3) The pressure of pressing and dehydration is 450KN / m; the temperature of drying and dehydration is 100°C.

Abstract

The invention relates to a method for preparing raw paper of facing paper from plant fibers. The method comprises the following steps: (1) preparing raw materials of plant fibers, inorganic fibers, sepiolite, EVA (Ethylene Vinyl Acetate) resin and a modifier; (2) adding water into plant fibers, stirring, then adding inorganic fibers, sepiolite, EVA resin and a modifier, and uniformly stirring to obtain a mixed material; (3) carrying out disc milling and pulping on the mixed material to obtain slurry; and (4) carrying out vacuum dehydration, squeezing dehydration and drying dehydration to prepare the raw paper of the facing paper. According to the invention, the environment-friendly, moisture-proof, antibacterial and formaldehyde-free process is prepared from the raw materials; the prepared facing paper is relatively good in flexibility and can be freely bent; the base paper is attached through the hot melt adhesive film, formaldehyde can be reduced, the film attaching process can be reduced, energy consumption is reduced, and the floor production period is shortened.

Description

technical field [0001] The invention belongs to the technical field of base paper preparation, and in particular relates to a method for preparing base paper for facing paper by utilizing plant fibers. Background technique [0002] The traditional decorative paper needs to be used in the downstream of the industrial chain. When the decorative paper is prepared, the decorative base paper is impregnated with a large amount of urea-formaldehyde glue and melamine-formaldehyde resin to make the decorative paper waterproof, anti-fouling and increase the strength. There will always be formaldehyde release on the facing paper, which is a health and safety hazard and not environmentally friendly. The traditional facing paper made by the above method is hard and cannot be curled, and can only be cut into flat sheets for use, which severely limits its application range and increases transportation and storage costs; and can only be hot-pressed and flat-bonded to wood-based panels The ...
