Problems solved by technology

[0002] U disk, the full name of USB flash drive, is a miniature high-capacity mobile storage product that uses a USB interface without a physical drive. It is connected to a computer through a USB interface to achieve plug-and-play. And present U disk volume is often all smaller and small and exquisite, often can be placed in the small corner of inconspicuousness after use, has caused people to have like this to have it to be crushed by mistake, and the hardness of existing U disk is also not good simultaneously. It is relatively low, and the pressure it can withstand is also small, so there is a demand for a high-hardness electronic U disk on the market

Abstract

The invention discloses a high-hardness electronic USB flash disk. The high-hardness electronic USB flash disk comprises a USB flash disk body, wherein the USB flash disk body is made of a high-hardness material; the high-hardness material is prepared from the following components in parts by mass: 45 to 55 parts of ABS (Acrylonitrile Butadiene Styrene) resin, 30 to 40 parts of polymethyl methacrylate, 4 to 8 parts of plasticizer, 7 to 13 parts of glass fibers and 5 to 10 parts of hardening additive; the hardening additive is prepared by mixing talc powder with calcium carbonate; counted by mass percentage, the content of the talc powder is 83 to 87 percent, and the content of the calcium carbonate is 13 to 17 percent. By adopting the mode, the high-hardness electronic USB flash disk has the characteristics of high wear resistance and high hardness; the USB flash disk can be prevented from being easily squashed, and the service life of the USB flash disk is prolonged.

Description

Technical field [0001] The invention relates to an electronic product, in particular to a high-hardness electronic U disk. Background technique [0002] U Disk, the full name of USB flash drive, is a miniature high-capacity mobile storage product that uses a USB interface and does not require a physical drive. It is connected to the computer through the USB interface to achieve plug and play. It is currently one of the main mobile storage devices. However, the current U disk is usually small in size, and is often placed in an inconspicuous small corner after use, which leads to a greater possibility of people crushing it by mistake. At the same time, the hardness of the existing U disk is also It is lower and can bear less pressure, so there is a demand for a high-hardness electronic USB flash drive on the market. Summary of the invention [0003] The main technical problem solved by the present invention is to provide a high-hardness electronic U disk, which can have the charact...
