Description
Technical field
The present invention relates to finishing paper technical field, be specifically related to the preparation method of a kind of woodgrained paper.
Background technology
Along with the fast development of the industries such as laminated flooring, dipping paper, face artificial board, furniture and fixtures, finishing paper is used
Amount is continuously increased, and quality improves constantly, and designs and varieties become increasingly abundant.But existing finishing paper is mostly through bleaching and to dye
Journey.Some finishing paper uses oxidative bleaches, such as liquid chlorine, hypochlorite etc., completes discoloration, thus obtains high whiteness
Slurry.Some finishing paper is when preparing paper stock, adds the pigment of different color, dyes.Bleaching and dyeing course are used
Chemicals health is had a certain impact, waste water is dealt with improperly and be will also result in environmental pollution.
Melamine-impregnated resin is respectively put into maceration tank and the second glue spreader by existing melamine impregnated paper
In storage glue groove, body paper is introduced maceration tank carries out impregnation for the first time, be dried for the first time, followed by second time impregnation, the
After secondary dipping, carry out second time and be dried, then cooling and shearing test package warehouse-in.This production process through twice impregnation, two
Secondary dry run, production process is complicated, and the performance of dipping paper also needs to be improved further.
Summary of the invention
In order to solve the problem that above-mentioned prior art exists, it is an object of the invention to provide the preparation side of a kind of woodgrained paper
Method, uses unbleached kraft paper, it is to avoid the health hazard of existing product bleaching process and environmental pollution, the woodgrained paper prepared
Have heat insulation, fire-retardant, not warpage, do not ftracture, the good characteristic such as easy to clean, and designs and varieties are many, pattern enrich attractive in appearance, color and luster is fresh
Gorgeous beautiful.
The present invention is to be achieved through the following technical solutions:
The preparation method of a kind of woodgrained paper, it is characterised in that comprise the steps:
A, printing: unbleached kraft paper is used water color ink printing；
B, impregnation: the unbleached kraft paper modified cyanurotriamide resin after printing or phenol-formaldehyde resin modified are carried out impregnation, wherein,
Described modified cyanurotriamide resin is that plasticizer modification prepares, and described phenol-formaldehyde resin modified is cyanurotriamide modified preparing；
C, be dried: by after impregnation unbleached kraft paper dry；
D, hot-forming.
In step a of the present invention, described unbleached kraft paper uses pure wood pulp production, does not bleaches, and fiber is wrapped in one uniformly
Rising, free from admixture, thus ensure good outward appearance, its grammes per square metre is 40 ~ 80 grams/m, for ensureing preferable printing effect, described
The smoothness of unbleached kraft paper is 115-125.
In step b of the present invention, for increasing the pliability of resin, described modified cyanurotriamide resin is by plasticizer modification system
, described plasticizer is Polyethylene Glycol or diethylene glycol.
For ensureing good impregnation resin content, the solid content of modified cyanurotriamide resin of the present invention is 56-60%；Described change
Property phenolic resin solid content is 52-55%.
The impregnation resin content of woodgrained paper is one of factor directly affecting the performance of decorative panel and cost, when impregnation resin content is less than
200%, the fire resistance of decorative panel is poor, when impregnation resin content is higher than 240%, can cause the waste of dipping solution, therefore, of the present invention
The impregnation resin content of unbleached kraft paper is 200%-240%.
The temperature of baking oven can affect the procuring degree of woodgrained paper, it is preferred that the temperature of drying of the present invention is 125-165
DEG C, the speed of service is 30-35 m/min.Drying area be divided into four control temperature sections, be respectively as follows: low temperature, middle temperature, middle high temperature,
High temperature.The temperature of low temperature exists: 125-130 DEG C, dries some water and low molecular weight volatile thing, it is to avoid woodgrained paper premature cure.Middle temperature,
Middle high temperature, high temperature temperature about at 135-165 DEG C, at this dry at a temperature of, whole drying course ensure resin dried
Journey carries out certain polycondensation reaction, and ensures have a certain proportion of pre-curing resin and uncured resin, thus in hot pressing
Time have good mobility, produce superior in quality decorative panel.
In step d of the present invention, described hot-forming temperature is 135-140 DEG C, and pressure is 12-14kgf, and the time is 5-7
Minute.
Procuring degree and fugitive constituent reflect the quality of resin condensation degree of dissolved in woodgrained paper, determine end product quality and outward appearance
Quality, under above drying process, the procuring degree of woodgrained paper of the present invention is 15%-20%, and fugitive constituent is 7.4%-7.9%.
The present invention compared with prior art, has the following technical effect that
(1) present invention uses unbleached kraft paper to carry out printing decorative pattern as base stock, it is to avoid the healthy danger that bleaching process is brought
Evil
And environmental pollution；Owing to belonging to primary colors, decrease the printing of printing link background color, reduce printing process；Use aqueous
Ink printing, environmental protection；
(2) production process of the present invention is simple, by controlling the technique bars such as impregnation resin content, the temperature of drying, procuring degree, fugitive constituent
Part, the woodgrained paper prepared is mainly used in the armour layer of the wood-based plate such as fibre board, particieboard, the various decoration materials being fabricated to
Material, have heat insulation, fire-retardant, not warpage, do not ftracture, the good characteristic such as easy to clean, and designs and varieties are many, pattern enriches attractive in appearance, color
Pool is bright-coloured beautiful.
