TW390840B - Abrasion-resistant, aesthetic surface layer laminate - Google Patents

Abstract

A thick aesthetic laminate surface layer is achieved by using pre-cured particulates of the impregnating resin along with an initial binder material and preferably also abrasion resistant mineral particles. The protective overcoating may be applied in a thick layer to give gouge resistance and a deep look. Because the impregnating resin and the pre-cured particulates have the same index of refraction, the transparency of the coating and the resultant clarity of the underlying decor sheet are excellent.

Description

Description of the invention (1) Background of the invention: The present invention relates to a decorative laminated surface, a wall inlay, a floor surface, and a process of a high-pressure decorative laminated plastic sheet. ΐ ... 4. Traditionally made. Laminated surface of resin laminated sheet for decoration decoration S is placed on many cows impregnated with phenolic resin. A decorative paper is placed on top of it and impregnated with melamine resin. . The paper is covered with a plastic surface that is as transparent as possible. It is suitable for tables and rafters. The surface of ladles and similar items, especially plates, is related to the way in which this laminate is made by synthesizing many layers together. Under normal circumstances, the combination is made of * paper made of leather paper, which is usually a printed matter or a single color. In the laminated board, it is usually on the decorative layer to protect the decorative paper —141— ( Please read the notes on the back before filling out this page.) The Consumer Cooperatives of the Central Bureau of Standards of the Ministry of Economic Affairs printed earlier US patents 3,3 7 3, 0 7 1 and 3, 1 3 to try to remove or simplify or improve the transparency. The paper technique is to immerse the decorative paper in a colorless phenolic resin at 2,000-60,000c ρ. As a result, the viscous paint dries on the saturation, thus forming a covering layer on the surface. The laminates made in the current way have never reached a large number of materials that should be used as flooring in commercial applications. It may be because of the need, which includes double treatment, that is, first impregnated and then coated. On the surface, this treatment has not proven to be any improvement over the traditional cover method, or it may be more because the overall quality does not meet the requirements of commercial purposes, such as cracked, wrinkled. The paper dimensions are applicable to the Chinese National Standard (CNS) A4 specification U10X2. .97), 5,643.

'w' .- S has used the same technology to make multi-layer tiles for floors for many years, but the sharpness of a single color is poor, that is, muddy like mud, so they are in business and industry The acceptance of the tiles is not ideal, and the commercial application of this type of floor tiles is mainly because they are laid on the ground and far from the line of sight, so people can tolerate this poor sharpness. Another later test discussed in U.S. Pat. Nos. 3, 96.8, 29.1 is to place a more transparent but fully protective protective layer on the decorative extinction sheet. The particle filler is barium sulfate. The patentee found that the light refractive index of barium sulfate is closer to the light refractive index of melamine resin than other fillers, so it can increase the transparency of the covering layer, and finally make it below it. The sharpness of the decorative paper can be improved. This product has never been commercially accepted, probably for the same reason as above. More recently, the current technology has made a revolutionary breakthrough because of the development of Ν VAMARARP technology.

Description of the invention (5) The detailed description of the embodiments will be clearer. One of the main features of this month of the issue is that it is used to remove unripe or part of the heat during the lamination process. The cooked laminated resin is a thermosetting resin particle having the same or approximately the same refractive index as the laminated resin that has been heat-set during the lamination process. The term "pre-cooked" means that the curing or a group of resin particles has been Be processed to the greatest possible extent, or at least to a maturation stage, at which time its hot melt viscosity is high enough to prevent the particles from dissolving in the liquid laminate resin and / or melt and flow under a te laminate condition , So: Ί '..'. In the process of manufacturing laminated plastic boards, the step of high pressure eight laminations will cause unnecessary penetration of the underlying paper, for example, the situation of penetrating into the decorative paper 〇 '~ According to the above description, in the process of manufacturing a high-pressure decorative laminate that complies with the N.E M A standard, the typical laminated resin used to penetrate / soak the decorative and covering paper under normal circumstances is a melamine resin, thus making melamine The resin is widely used in the upper layer or the layers of the present invention. Therefore, the melamine resin is preferably used as the particle of the pre-cured thermosetting resin. However, other resin systems may also be used. For example, polyester , Urea formaldehyde, dimethoxamine, epoxy, polyurethane, curable acrylic, and a mixture of these resins (Please fill in this page again). Pre-cooked polymer particles can therefore be selected from melamine resins, polyesters, epoxy resins, curable acrylics, etc. or their mixtures. 9 In some cases In order to obtain special effects, it is also possible to use certain non-coexisting mixtures, for example, pre-cooked polyester resin particles or polyurethane resin particles and matured melamine resin particles and Liquid melamine laminated resin; however, under normal circumstances, the cured paper and the liquid paper size are applicable to the Chinese National Standard (.CNS) A4 specification (210 × 297 mm-).

These resins can still be partially dissolved in the liquid laminated resin, so that they can melt and flow into the lower paper, but this kind of lightly matured particles The quantity must not be so large as to lose the properties of the desired product, that is, the plastic composite laminated board finally synthesized must have a large part of a transparent protective cover made of pre-cure resin. • If the transparent cover is very thin, but 50% or more of it is contained in the composition. It contains ketone milled mineral particles. In addition to the transparent protective layer covering the body paper, the laminated plastic sheet of the present invention is preferably manufactured in a standard manner, and Tan Hao has a traditional structure, that is, it contains 2 to 8 benzene chisels.

Printed by the Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs A7 _____ B7___ 5. Description of the Invention (P ·) The protective coating can be applied to decorative paper in many ways. In short, these are two-step processes that are similar to the ARP method in US Patent No. 4,255,480; a single-step process similar to that in U.S. Patent No. 4,7 1 3, 1 3 8 ; One with US Patent 1334 ,! 51 7, 2 3 5 and US 4, 5 2 0, 0 6 2 similar conversion process; and a hearty and glossy process, where the protective cover layer composition is directly coated on a wooden board or similar material, and then applied Press firmly. In a more ideal form of use in the two-step method, the composition of the coating is composed of small particles of vaporized aluminum or other best-sized flat: abrasion-resistant particles, about 1 to 30 microns in size, and a maximum particle size of 2 50 um , And preferably, a mixture of pre-cooked resin particles with a maximum particle size of 100 um and a smaller amount of microcrystalline fiber particles, all ingredients are dispersed in a stable water-containing slurry. Vaporized aluminum particles are so small that they do not constitute a visually disturbing factor in the final product and can be used as abrasion-resistant materials, while microcrystalline fiber particles are used as the best starting binder material. As everyone knows, the initial adhesive must coexist with the resin system used in the lamination process, usually melamine resin or polyester resin system in some examples of low-pressure laminated plastic plates. Microcrystalline cellulose has this function and can stabilize small particles of vaporized aluminum and pre-cured resin that are decorative on the surface of paper. In this way, the most ideal slurry composition consists of a mixture of small particles of pre-vapourized aluminum and pre-cooked »resin particles and fewer of the most crystalline cellulose particles, all of which are dispersed in water.

In general, it is found that 2 to 10 parts of microcrystalline cellulose androgen is calculated with MM and 20 to 120 parts of vaporized aluminum and pre-cooked particles are the best results; but Μ, it is possible Outside this range, the amount of pre-cured resin is the most. One to six parts of pre-cured resin particles are prepared for each part of mineral particles. It is known that not only can it be produced outside this range, but also It is possible to produce a suitable product with a thick transparent protective cover without using any mineral particles. The amount of water in the slurry must also be considered: consider the use of treasure. "If there is too little water, the slurry will become too thick. And it ’s hard to cast; on the contrary, too much dehydration will make it difficult for Deng to keep the thickness of the It layer uniform during the smearing process. Therefore, the slurry containing 2.0% wt of olivine vitamin and approximately 2 4% wt of oxidation and pre-cooked resin particles is stable based on the weight of water, that is, alumina and pre-cooked resin The particles do not solidify; but if more than 3.5% wt of microcrystalline cellulose is used, and about 24% wt of alumina and pre-cure resin particles, the slurry becomes very hard, based on the weight of water Difficult to cast. The mineral-containing particle combination preferably contains a small amount of wetting agent, preferably a non-ionic wetting agent, and silane. The amount of wetting agent is not critical, but only a very small amount is required, and an excess of wetting agent does not provide any benefit. According to traditional practice, vine retention agents, release agents, catalysts and / or antifoaming agents can be used. If silane is used as a coupler, it can chemically combine non-organic particles of oxidized or Jt · he with pre-cooked melamine granules after soaking and curing.

Description of the invention (1Θ) The combination of the daughter and / or melamine base, and so on It can provide better abrasiveness of acetone. · Because the vaporized aluminum particles are chemically combined with melamine particles in addition to mechanical methods, they can enjoy a longer service life under abrasion conditions. Silicone should be selected from those that match the specific thermosetting resin used ... '; in this regard, silanes with a halogen group, such as gamma-aminopropyltrimethoxysilane, and Melamine resin is particularly effective when used. The amount of silane used does not have to be very large, and in fact its amount is only 0.5% of the weight of the tiny mineral particles used. This can effectively increase the shooting properties of the final accumulated plastic plate; the maximum recommended amount is 2% of the weight of gasified aluminum or other hard particles is the upper limit, because no larger amount can get better results, but only increases the cost of raw materials. The decorative paper is dried after applying the aforementioned coating composition, and then dipped in an appropriate thermosetting resin in the normal manner, such as melamine resin or polyester. The use of microcrystalline cellulose as a binder must be dried at high temperature before the decorative paper is impregnated with melamine resin. As such, the minimum drying temperature is approximately 14 0 F, and the best drying temperature is 2 40-2 7 0 F.
