Description
The present invention relates to a resin sheet having a two-layer structure having a pearlescent luster or pattern, and more particularly to a resin sheet comprising: I) a base layer containing an ABS resin and a perl master batch; And II) a resin sheet of a two-layer structure having a perforated luster or pattern in which a skin layer of a transparent PMMA resin is laminated on the base layer.
Resin products based on plastic materials are used in many areas of daily life in modern people. Depending on the field of use, various properties and physical properties required for resin products, such as household appliances, furniture, food or cosmetic packaging containers, kitchen utensils, bathtubs or shower booths, In order to enhance the value, the surface of the resin product requires aesthetics including a beautiful gloss and a pattern, and various prior arts related thereto are known.
Among these prior arts, the blend resin product of the styrene-butadiene block copolymer and the crystalline polypropylene homopolymer has excellent mechanical properties such as impact strength and exhibits a beautiful pearl pattern or gloss. However, the weather resistance, scratch resistance, It has a disadvantage that it is difficult to apply it to applications such as a bathtub or a shower booth because of its low stress cracking resistance (Patent Document 1).
In addition, the applicant of the present patent application has already manufactured and extruded an extruded resin containing a core layer made of ABS resin and a skin layer containing a blend of PMMA and styrene-acrylonitrile (SAN) resin, Although it was possible to show a pearl feeling without using an expensive additive, mechanical properties were deteriorated over a long period of time, and there was a limit to maintaining the pearl luster (Patent Document 2).
Further, the inventors of the present invention have found that when the ABS resin is used as a base layer, a core layer containing PMMA and metal powder, and a skin layer containing a MMA-acrylate copolymer resin or a skin layer containing an impact-modified PMMA, Have been patented. However, all of these resin sheets have a disadvantage in that the production process is complicated and the production cost is relatively high as a three-layered resin sheet (Patent Documents 3 and 4).
Therefore, the inventors of the present invention have repeatedly conducted studies on a resin sheet having a perl glossy or pattern. As a result, they have found that when ABS resin is mixed with a material having a pearling property to form a base layer, and a skin layer of a transparent PMMA resin is laminated It is possible to simplify the production process and to greatly reduce the production cost by mass production of a resin sheet having a good mechanical property and a pearly luster even with a double-layered resin sheet alone, thereby completing the present invention.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and it is an object of the present invention to provide a pearlescent varnish or varnish which is excellent in mechanical properties and excellent in surface gloss and aesthetics, To thereby provide a resin sheet having a pattern.
In order to achieve the above-mentioned object, the present invention relates to a laminate comprising: I) a base layer containing an ABS resin and a pearl master batch; And II) a resin sheet of a two-layer structure having a perforated luster or pattern in which a skin layer of a transparent PMMA resin is laminated on the base layer.
The base layer is composed of 70 to 90% by weight of an ABS resin and 10 to 30% by weight of a pearl master batch.
The pearl master batch comprises 95 to 99.5% by weight of an ABS resin and 0.5 to 5% by weight of gold, silver, aluminum, titanium, manganese, chromium, magnesium or a mixture thereof.
The particles have an average particle diameter of 50 to 200 mu m.
Wherein the base layer further comprises a pearlescent brightening agent selected from the group consisting of marble, mica pigment, pearl powder, glass powder and mixtures thereof.
The thickness of the skin layer is 10 to 15% of the total thickness of the resin sheet.
The resin sheet having a two-layer structure having a pearly luster or pattern produced according to the present invention is excellent in mechanical properties and excellent in surface gloss and aesthetics. Since the manufacturing process is simple and the production cost is reduced, , A carrier, a bathtub, or indoor and outdoor architectural finishing materials.

(Example)
A pellet (first pellet) containing 90% by weight of an ABS resin and 10% by weight of a pearl master batch (a pearl master batch containing 99.5% by weight of ABS resin and 0.5% by weight of aluminum particles having an average particle diameter of 200 m previously blended) And transparent PMMA resin pellets (second pellets) were respectively prepared. The first and second pellets were put into a feed block through a twin co-extruder set at different temperatures of 260 and 250, respectively, to form a skin layer / substrate layer. The laminated resin was passed through a die and processed into a sheet to obtain a resin sheet having a two-layer structure. At this time, the thickness of the skin layer was adjusted to 0.4 mm to finally prepare a resin sheet having a thickness of 4 mm.
( Test Example )
The mechanical properties and pearliness of the two-layered resin sheet prepared from the above Example and the aluminum powder-containing PMMA sheet and aluminum powder-containing ABS sheet having the same thickness as the control group were measured by the following method.
(1) Weatherability was measured according to the ultraviolet ray test method based on the artificial promoting weatherability test standard, and the color difference (ΔE) was compared after 200 hours.
(2) Izod impact strength was measured according to ASTM D256 method for impact resistance.
(3) A known pencil hardness measurement method was used for the scratch resistance.
(4) According to JIS K7105 method, the surface gloss was measured with a gloss meter at a slope angle of 60 DEG.
(5) The pearl luster or pattern was visually observed to evaluate a beautiful pearl luster or pattern (?), A pearl luster or a pattern was weak (?) And no pearl luster or pattern (x).
