Abstract
The invention discloses a preparation method of fireproof facing paper. The preparation method includes the following steps that kraft paper is subjected to impregnation through an impregnating glue solution, and the kraft paper obtained after impregnation is dried and then reeled into the finished product. The impregnating glue solution is prepared from, by weight, 40-65 parts of phenolic resin or modified phenolic resin, 30-50 parts of melamine resin or modified melamine resin and 5-10 parts of fire retardant. Through impregnation of the impregnating glue solution prepared from the phenolic resin or modified phenolic resin, the melamine resin or modified melamine resin and the fire retardant, the obtained facing paper has good fireproof performance, and is light in color and good in facing effect, and original wood grain can be exposed when the facing paper is applied to a decorative board.
Description
Technical field
The present invention relates to decorative paper technical field, be specifically related to the preparation method of a kind of decorative paper of preventing fires.
Background technology
Decorative paper has good dicoration, is therefore widely used in wood-based plate decoration material, but paper material is easily
Burning, and burning velocity is fast, easily causes intensity of a fire fast development.Therefore, how to strengthen while keeping decorative paper decorative effect
Its fire protecting performance becomes the focus of research, the decorative panel of Recent study fire prevention papery and fireproof decoration plate application architecture indoor dress
Repair increasing with other aspects.
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 is complicated, preventing of dipping paper
Fire performance 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 a kind of fire prevention decorative paper, should
Fire prevention decorative paper have of light color, finishing effect good and has preferable fire protecting performance simultaneously.
The present invention is to be achieved through the following technical solutions:
The preparation method of a kind of decorative paper of preventing fires, it is characterised in that comprise the steps: to be carried out kraft paper by dipping glue
Impregnation, the kraft paper after impregnation is through drying, and then rolling finished product, wherein, described dipping glue is counted by weight, including such as
Lower component:
Phenolic resin or phenol-formaldehyde resin modified 65-40 part
Melmac or modified cyanurotriamide resin 30-50 part
Fire retardant 5-10 part.
Described phenol-formaldehyde resin modified is by heterocyclic compound or containing nitrogen compound, concrete such as polyamide, dicyandiamide, benzene
Phenolic resin is modified preparing by amine, Cardanol, bisphenol-A etc.；
Described fire retardant is phosphorus-nitrogen containing flame retardant, red phosphorus and compound, nitrogen system or bromide fire retardant.
Described modified cyanurotriamide resin be by polyvinyl alcohol, thiourea, containing phenol heterocycle, phenol or lignin to melamine
Amine prepares after being modified.
The dipping glue of the present invention is by phenolic resin or phenol-formaldehyde resin modified, melmac or modified cyanurotriamide
Resin and fire retardant mix.Owing to dipping glue has preferable flame resistance, therefore improve the veneer after its impregnation
The fire protecting performance of paper.The mixing of both phenolic resin or phenol-formaldehyde resin modified, melmac or modified cyanurotriamide resin
Parts by weight ratio is different, the color of decorative paper and fire resistance can be produced impact, when the two ratio is less than 40:50, and patch
The color of facial tissue is shallower, but its fire resistance has a declining tendency；When the two ratio is higher than 65:30, the color of decorative paper is relatively
Deeply, reducing finishing effect, fire resistance is improved little, and therefore, the preferred phenol-formaldehyde resin modified of the present invention is and modified cyanurotriamide
The mixed proportion of resin is 65-40:30-50.
The solid content of the dipping glue of the present invention is 50-55%, thus ensures good impregnation resin content.
The impregnation resin content of fire prevention decorative paper is one of factor directly affecting the fire resistance of decorative panel and cost, works as impregnation resin content
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, the present invention
The impregnation resin content of described kraft paper is 200%-240%.
The temperature of baking oven can affect the procuring degree of fire prevention decorative 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 decorative paper is the most solid
Change.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
In dry run, carry out certain polycondensation reaction, and ensure have a certain proportion of pre-curing resin and uncured resin, from
And good mobility is had when hot pressing, produce superior in quality decorative panel.
Procuring degree and fugitive constituent reflect the quality of resin condensation degree of dissolved in decorative paper, determine end product quality and outward appearance
Quality, under above drying process, the procuring degree of fire prevention decorative paper of the present invention is 10%-15%, and fugitive constituent is 7.8%-
8.1%。
The present invention compared with prior art, has the following technical effect that
(1) present invention is by by phenolic resin or phenol-formaldehyde resin modified, melmac or modified cyanurotriamide resin and resistance
The dipping glue impregnation of combustion agent composition, the decorative paper obtained has preferable fire protecting performance, and of light color, when being applied to decorative panel
Can expose wood grain, finishing effect is good；
(2) present invention is by controlling the process conditions such as spread, the temperature of drying, procuring degree, fugitive constituent, on the one hand improves
The fire protecting performance of decorative paper, on the other hand reduces cost, has preferable economic benefit.
