Description
Technical Field
The invention relates to a facing adhesive film paper, in particular to a facing adhesive film paper capable of preventing finger prints, and a preparation method and application thereof.
Background
The surface mount adhesive film Paper is a Melamine-Impregnated adhesive film Paper (also called Melamine-Impregnated Bond Paper), which is a kind of adhesive Paper made by impregnating a plain base Paper or a printing decorative Paper with an amino resin (Melamine-Formaldehyde resin, Urea-Formaldehyde resin) and drying to a certain extent and having a certain resin content and volatile matter content. The decorative surface adhesive film paper can be mutually glued or glued with an artificial board base material through hot pressing to manufacture the melamine veneer.
The traditional production of the veneer adhesive film paper mainly comprises four procedures: 1) uncoiling: the coiled printing base paper is placed on a gum dipping production line, and the paper is manually pulled to pass through a tension roller, a breathing roller, a back coating roller, a dipping roller, a metering roller, a leveling roller and the like, so that the base paper is normally and automatically pulled under the drive of a paper leading chain, and the working procedures of primary dipping, secondary dipping, stacking and the like are completed. 2) First soaking: for the first sizing, urea-formaldehyde resin is generally used as an adhesive in the normal process. The air in the paper fiber is driven away under the action of the breathing and back coating rollers, then the original paper is completely soaked in the resin in the impregnation roller, the gluing amount is controlled by the metering roller, and the paper surface is smoothed by the smoothing roller and then enters the oven for primary drying. The urea-formaldehyde resin is changed from liquid to solid, but certain volatile components and pre-curing degree need to be strictly controlled. 3) Second leaching: after the first section of drying oven comes out, the second gluing is carried out, the upper surface and the lower surface of the paper are generally coated with melamine formaldehyde resin, the paper enters a second section of drying oven for drying after being metered and smoothed, and certain volatile matters and pre-curing degree need to be strictly controlled. 4) Stacking: after the paper comes out of the oven, the paper passes through a cooling roller and a leveling roller, and then the paper is cut to size according to the order requirement, stacked and packaged. Wherein, the gluing amount refers to the ratio of the weight of resin in the adhesive film paper to the weight of base paper; the volatile matter is the ratio of the weight of the volatile components in the adhesive film paper to the total weight; the degree of precuring refers to the ratio of the weight of the fully cured non-hydrolyzable resin to the weight of the total resin in the film paper.
With the improvement of living standard and aesthetic sense of people, the consumption trend is changing continuously, and many consumers require fashionable, personalized and magnificent home decoration materials and environment-friendly, clean, safe and high-quality materials. The artificial board is decorated with facing adhesive film paper to cover and eliminate various defects in the surface of the artificial board and to make it possess clear, elegant, harmonious and beautiful appearance. However, the decoration surface is often contacted by both hands of people, so that a finger print is formed on the decoration surface, and viewed from a reflecting angle, the appearance of the decoration material is greatly influenced by the obvious finger print, people hope to eliminate the influence of the fingerprint on the decoration, so that the decoration material cannot transfer or adhere to the fingerprint, the decoration surface is kept in a non-sticky state, and the coated ink layer can fully embody the beautiful and gorgeous effect. And the finger print contains ingredients such as water, inorganic salts, urea, oil, and the like. A large amount of dust, bacteria and the like are bred after being attached to the decorative surface for a long time, and the bacteria are easily introduced to the human body through repeated contact of hands and the decorative surface.
Today, anti-fingerprint technology has been applied to the industries of electronics, glass, metal and the like, but has not been applied to the furniture decoration industry.

The invention has the beneficial effects that:
the melamine formaldehyde resin used for coating is specially treated, so that the melamine formaldehyde resin film has hydrophobic and oleophobic properties, thereby realizing the lotus leaf effect of the facing adhesive film paper product and having the effect of fingerprint resistance; and the modified melamine formaldehyde resin also contains matte powder, so that an inner matte effect can be provided.
The modified melamine formaldehyde resin with the matte function used for the surface coating of the veneer adhesive film paper has the following specific advantages:
1. the hydrophobic and oleophobic auxiliary agent is selected as the fluorocarbon surfactant in the modified melamine formaldehyde resin, and the fluorocarbon surfactant has the outstanding advantage of extremely high surface activity and is the highest surface activity in the currently known surfactants. The dosage of the fluorocarbon surfactant is generally 0.05-0.2% (accounting for the mass percent of the melamine formaldehyde resin), thus meeting the requirement. The amount of the traditional hydrocarbon is 0.2-1.0%. The introduced fluorine completely or partially replaces hydrogen in the traditional hydrocarbon chain, and forms a special surfactant taking the end of the fluorocarbon chain as a hydrophobic and oleophobic group, so that the special surfactant is endowed with excellent hydrophobic and oleophobic properties, high surface activity, good chemical stability, thermal stability and other special properties, the activity of the fluorocarbon surfactant is highest, and the surface tension of the substance can be reduced to be very small by using a small amount of the fluorocarbon surfactant. The nonpolar end of the surfactant is composed of fluorocarbon chains, and the quantity and the positions of the introduced fluorine atoms have important influence on the overall performance of the surfactant, and the hydrogen atoms are replaced by the fluorine atoms, which is equivalent to the replacement of carbon-hydrogen bonds by fluorocarbon bonds, so that the nonpolar end of the surfactant is both hydrophobic and oleophobic. The stability of the selected non-ionic fluorocarbon surfactant is higher than that of the selected ionic fluorocarbon surfactant, so that the influence of electrolyte, pH value and mineralization degree is relatively small. The non-ionic fluorocarbon surfactant is added into the coated melamine formaldehyde resin according to the mass ratio of 0.05-0.2%, the fluorocarbon surfactant gradually migrates to the surface layer of the film in the film forming process of the melamine resin, the gaps after water evaporation are occupied by the fluorocarbon surfactant which migrates to the surface layer and are arranged in a close and ordered manner, the fluorine-containing alkyl group on the surface layer greatly reduces the surface tension of the melamine formaldehyde film, endows the film with hydrophobic and oleophobic properties, and improves the anti-fouling capability of the paint film.
2. The invention adopts the extinction powder emulsion in the modified melamine formaldehyde resin. The dispersion of silica powder in polymer is always a very difficult problem, and in order to obtain a composite material with excellent performance, the material must be uniformly dispersed in the polymer. In actual production, the melamine formaldehyde resin used in each batch is measured by tons, and if the extinction powder is directly added for high-speed dispersion, the extinction powder is not provided with a large high-speed dispersion machine and is not scientific, and the dispersion effect is far from the use requirement. Therefore, the matting powder is added with carrier resin for pre-dispersion to prepare the emulsion additive.
3. The modified melamine formaldehyde resin is added with various additives before use, so that various performances of the resin can be improved. The raw materials can be directly put on a production line for gum dipping production after being uniformly stirred.
