Description

[0001] The present invention relates to a two-layer resin sheet having a pearl-like luster pattern,

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.

1, an ABS (acrylonitrile-butadiene-styrene) resin is used as the polymer material constituting the base layer 10 of the resin sheet 100 of the two-layer structure according to the present invention. ABS resin is a copolymer having acrylonitrile chemical resistance, butadiene impact resistance and styrene excellent processability and is widely used as a material for furniture or bathtubs.

The base layer 10 contains a perlmaster batch 30 for imparting a pearly luster or pattern. In general, the masterbatch is produced by mixing a polymer resin and a functional additive in order to add functionality to a polymer resin such as a plastic or a rubber. The masterbatch is produced in the form of a chip or a pellet. In the present invention, A functional additive exhibiting gloss or pattern is previously compounded and molded into a pellet form.

The base layer 10 is preferably composed of 70 to 90% by weight of an ABS resin and 10 to 30% by weight of a pearl master batch. If the content of the ABS resin forming the base layer 10 is less than 70% When the content is more than 90% by weight (when the content of the pearl master batch is less than 10% by weight), the pearl luster or pattern characteristics Can be lowered.

Metal particles such as gold, silver, aluminum, titanium, manganese, chromium, magnesium, or mixture particles thereof can be used as the functional additive showing the pearl luster or pattern. Among them, .

The perl master arrangement 30 preferably comprises 95 to 99.5% by weight of ABS and 0.5 to 5% by weight of gold, silver, aluminum, titanium, manganese, chromium, magnesium or their mixture, It is difficult to obtain uniform pellets in which the metal particles are uniformly distributed during the processing according to the blending of the cotton perlite master batch 30.
