The information reproducing unit 372 may be a liquid crystal display, a thin film transistor-liquid crystal display, an organic light-emitting diode, a flexible display, a three- (3D display), and the like, but the present invention does not limit the kind of the information reproducing unit 372. [

The second control module 380 is provided with a bird observing program to control the operation of each component by executing the bird observing program. That is, the second control module 380 controls the operation of the local server 200 by executing the bird observation program, and stores and outputs the radar image provided in real time from the local server 200.

The control server 300 includes a third communication module 310, a connection display module 320, a user management module 330, a second storage module 340, a second operation setting module 350, (Not shown) that accommodates the operation module 360, the information output module 370, and the second control module 380. At this time, the case may be made of a polypropylene resin composition. That is, the case may be molded with a polypropylene resin composition containing (A) crystalline polypropylene, (B) ethylene butyl acrylate polymer, (C) styrene type hydrogenated block copolymer and (D) inorganic filler. Therefore, in the present invention, such a case can be molded with such a polypropylene resin composition, and excellent coating adhesion and excellent impact resistance can be exhibited without applying a primer.

 (A) crystalline polypropylene

The crystalline polypropylene (A) may comprise at least one selected from a crystalline polypropylene homopolymer and a propylene-alpha olefin crystalline copolymer comprising C2 to C20 (excluding C3) alpha-olefin monomers .

Specific examples of the alpha-olefin monomers may be ethylene, 1-butene, 1-pentene, 1-hexene, 4-methylpentene, 1-heptene, 1-octene and 1-decene and preferably ethylene. The propylene-alpha olefin crystalline copolymer may be, but is not limited to, a block copolymer or a random copolymer.

The content of the polymerization unit of propylene in the propylene-alpha-olefin crystalline copolymer is not particularly limited, but is preferably 50 wt% or more in the copolymer.

The crystalline polypropylene (A) is not particularly limited in terms of stereoregularity, but any crystalline polypropylene that can achieve the object of the present invention can be used without limitation, and more specifically, C-NMR (nuclear magnetic resonance Spectrum) may be from 0.80 to 0.99, and preferably from 0.85 to 0.99.

The melt flow index (MFI, 230 ° C, 2.16 kg load) of the crystalline polypropylene (A) may be 20 to 60 g / 10 min, preferably 20 to 50 g / 10 min.

The crystalline polypropylene (A) may be contained in an amount of 44 to 57% by weight based on the resin composition. If the content of the crystalline polypropylene (A) is less than 44% by weight, the coating adhesion may be deteriorated. If the content of the crystalline polypropylene is more than 57% by weight, the flexural modulus and the coating adhesion may be lowered.

(B) Ethylene butyl acrylate polymer

In the ethylene butyl acrylate polymer (B), butyl acrylate may be contained in an amount of 20 to 40% by weight, preferably 25 to 40% by weight, based on the polymerization unit.

The ethylene butyl acrylate polymer (B) may be contained in an amount of 9 to 21% by weight based on the polypropylene resin composition. When the content of the ethylene butyl acrylate polymer (B) is less than 9% by weight, the coating adhesion is poor, and when the content is more than 21% by weight, the flexural modulus may remarkably decrease.

The melt index (190 ° C, 2.16 kg load) of the ethylene butyl acrylate copolymer (B) may be 5 to 250 g / 10 min, and preferably 10 to 200 g / 10 min.

(C) a styrene-based hydrogenated block copolymer

(C) styrene-based hydrogenated block copolymer can further improve paint adhesion and impact resistance to the polypropylene resin composition.

The styrene-based hydrogenated block copolymer (C) is preferably a styrene-ethylene-butene-styrene block copolymer (SEBS), a styrene-ethylene-propylene- , Styrene-ethylene-isoprene-styrene block copolymer, acrylonitrile-butylene-styrene block copolymer and the like, preferably styrene-ethylene-butene-styrene block copolymer (SEBS) and Styrene-ethylene-propylene-styrene block copolymer (SEPS).

The styrene-based hydrogenated block copolymer (C) may be contained in an amount of 7 to 21% by weight, preferably 10 to 18% by weight, based on the polypropylene resin composition. When the content of the styrene-based hydrogenated block copolymer (C) is less than 7% by weight, the coating adhesion is decreased. When the content is more than 21% by weight, mechanical properties such as rigidity and coating adhesion may be lowered.

(D) Inorganic filler

The inorganic filler may be used to reinforce the rigidity of the polypropylene resin composition. The inorganic filler may be at least one selected from the group consisting of talc, barium sulfate and calcium carbonate, preferably talc.

The particle size of the talc can be determined from the grain size of 50% by weight accumulated from the particle cumulative distribution curve measured according to the laser diffraction method, and the average particle size can be 10 탆 or less, preferably 0.5 to 8 탆. If the particle diameter of the talc is out of the above range, the flexural modulus may be lowered, which is not preferable.

The talc may contain various organic titanate-based coupling agents, organic silane coupling agents, unsaturated carboxylic acids, or anhydrides thereof in order to improve the adhesiveness or dispersibility with the polymer. Grafted polyolefins, fatty acids, fatty acid metal salts, fatty acid esters, and the like.

The inorganic filler may be contained in an amount of 10 to 23% by weight, preferably 10 to 21% by weight, based on the polypropylene resin composition. If the content of the inorganic filler is less than 10% by weight, the flexural modulus may be insufficient or the coating adhesion may be deteriorated. If the content of the inorganic filler is more than 25% by weight, the impact resistance may be deteriorated.

The polypropylene resin composition according to the present invention may further contain other additional components as long as the effect of the present invention is not significantly impaired. More specifically, it is preferable to use a solvent, a phenol-based and phosphorus-based antioxidant, a hindered amine-based, a benzophenone-based, benzotriazole-based weathering deterioration inhibitor, an organic aluminum compound, A dispersant represented by metal salt of stearic acid, a coloring material such as quinacridone, titanium oxide, and carbon black, but the present invention is not limited thereto.

The polypropylene resin composition according to the present invention can be produced according to a process for producing a resin composition known in the art, for example, by mixing the components in a stirring-mixing apparatus such as a Hensel mixer, a super mixer or a tumbler mixer And the mixture is agitated-mixed for 1 to 10 minutes and can be pelletized by melting and kneading at a temperature of 180 to 230 DEG C using a mill or an extruder.

In the present invention, the case is made of a molded article made of the polypropylene resin composition, but the molded article can be produced by any molding method such as injection molding, extrusion molding, and the like, but is not limited thereto. In this case, an insulating film may be formed on the outer surface of the molded product of the polypropylene resin composition.
