Abstract

PURPOSE: A storage case for electronic components is provided to reduce the production cost using biodegradable resin and to prevent an accident of electrification by adding a material having excellent conductivity to the biodegradable resin. CONSTITUTION: A case(10) is made up of 50wt% of polycaprolactone, 30wt% of dextrin, 10wt% of polyethylene, and 10wt% of carbon black. The dextrin is used for naturally decomposing biodegradable resin in the ground. The carbon black is for the improvement of conductivity. Many partitions(12) are formed in the case, so that electronic components(20) are aligned at a specific interval. Since the case is made up of resin having excellent durability, breakage of the electronic components is prevented. Using the carbon black prevents an accident of electrification and disconnection due to electrification.

Description

Electronic part storage case {Custody case of an electron parts}

The present invention relates to an electronic component storage case, and more particularly, by adding carbon black to a biodegradable resin composed of PCL (Poly CaproLactone), starch, and PE (Poly Ethylene) to improve electrical conductivity, Even if it is buried in the ground, there is no need to worry about environmental pollution. Also, when storing and transporting electronic components, the present invention relates to an electronic component storage case that can prevent an accident of charging due to contact from the outside.

In general, since electronic components such as RAM and ROM are configured in the form of integrated circuits, they are susceptible to external shocks and easily damaged by weak currents such as static electricity. Therefore, special care should be taken when storing and transporting these electronic components. In view of this, there are some cases in which injection molded cases are made of durable synthetic resin, but since the resin is a pollutant that does not rot easily, it tended to be avoided by the consumer.

Recently, due to the serious environmental pollution of waste plastics, many researches on degradable plastics have been conducted. This includes research on photodegradable plastics and biodegradable plastics. Can be distinguished. As far as research on biodegradable films is concerned, ECOPLASTICS, DOWCHEMICAL, UNION CARBIDE CORP., Etc. have developed photodegradable plastics with carbonyl group, ampacet, etc. The photodegradable plastic film was developed by mixing the photodegradable additives, but it was expensive and had the disadvantage of not being decomposed when buried in the soil.

In addition, FERRUZZI, BATTELLE and St Lawrence Starch have developed biodegradable plastics using starch or modified starch, and ICI AMERICAS has developed polyhydroxy. We developed biodegradable plastics synthesized with butylate, and AIR PRODUCTS has developed biodegradable plastics copolymerized with polyvinyl alcohol (PVA), but the disadvantage is that they are expensive to manufacture or do not exhibit sufficient physical properties. there was.

The present invention was developed in view of the conventional problems, and an object of the present invention is to construct a case that can arrange and store electronic components using a durable biodegradable resin at a low price and to provide a material having excellent electrical conductivity to the biodegradable resin. The present invention provides an electronic component storage case which prevents an accident from occurring when it is added and transported and stored.

In order to achieve the above object, the present invention provides an electronic component storage case having a plurality of compartments that can contain electronic components therein, the case is 50% by weight PCL, 30% by weight starch, 10% by weight PE, carbon Black is composed of 10% by weight is configured to excellent biodegradability and electrical conductivity.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The case 10 to which the electronic component 20 can be plugged is composed of a durable biodegradable resin and does not have to worry about environmental pollution because it rots well even when it is buried in the ground. The case 10 has a plurality of partitions 12 formed at the left and right sides of the partition 11 in the inner center. These partitions 12 are spaced apart by the width of the electronic component, and these partitions 12 align the electronic components without interfering with each other. And each partition 12 is formed with a handle groove 13 so as to easily hold the parts by hand.

Case 10 of the present invention is composed of PCL (Poly CaproLactone), starch and PE (Poly Ethylene) and additionally carbon black (Carbon Black) is added. They are mixed with 50% by weight of PCL, 30% by weight of starch, 10% by weight of PE and 10% by weight of carbon black. Starch is used when manufacturing biodegradable resins. When starch is buried in the ground due to this starch, it naturally ferments and decays. Carbon black also improves electrical conductivity and prevents charging of electronic components.

Carbon black is used for low cost and carbon fiber is used for high cost. When carbon fiber is used, PCL is mixed by 50% by weight, starch by 33% by weight, PE by 10% by weight, and carbon fiber by 7% by weight, respectively.

In the present invention configured as described above, a plurality of partitions 12 into which the electronic component 20 can be inserted are provided in the case 10. Therefore, these electronic parts can be arranged at regular intervals and stored, and since the case is made of a durable resin, there is no need to worry about damage to the electronic parts.

And because the resin is biodegradable, it rots well when landfilled. Starch and PCL contained in the resin are the main components of the resin and they decay when they are landfilled. In addition, the carbon black contained in the resin prevents the charging accident of the case 10. Since carbon black is excellent in electrical conductivity, even if a charging accident is caused by contact from the outside while carrying a case, static electricity or the like is leaked to the outside and does not affect the electronic component. Therefore, a circuit short circuit of the electronic component can be prevented.

As described above, according to the present invention, a case for aligning an electronic component that is an integrated circuit is made of biodegradable resin so that there is no need to worry about environmental pollution. In particular, durability can be improved to safely transport and store the component. In addition, when the carbon black and the carbon fiber are added to the case, the electrical conductivity is improved, thereby preventing the charging accident caused by the static electricity.
