Problems solved by technology

[0003] At present, the single-layer thickness of the hard disk silicone protective cover on the market is mostly between 1-2mm, which can have a good heat dissipation effect, but the effect of shock resistance and drop resistance is average, and if the thickness is higher than 3mm, the protective cover will be damaged. The heat dissipation effect is obviously reduced, which will easily cause the mobile hard disk to heat up, and also easily cause damage to the stored data. Therefore, due to the limitation of heat dissipation performance requirements, it is difficult for the hard disk silicone protective cover to meet people's ideal anti-seismic protection effect, which brings inconvenience to people's use.

Abstract

The invention relates to a mobile storage hard disk silica gel protective sleeve and a preparation method thereof, and belongs to the field of silica gel. The silica gel protective sleeve for the mobile storage hard disk is prepared from the following raw materials through mixing and mould pressing: vinyl silicone oil, hydrogen-containing silicone oil, silicon resin, an inhibitor, a catalyst and a heat-conducting filler, the heat-conducting filler is prepared from the following raw materials through mixing, high-temperature drying and crushing: modified polyurethane fiber, graphene, N-phenylamino-polyhedral oligomeric silsesquioxane, allyl alcohol glycidyl ether, metal oxide, boron nitride and an auxiliary agent. The silica gel protective sleeve has a high heat conductivity coefficient, the mobile storage hard disk with the thickness larger than 3 mm can show an ideal heat dissipation effect, silica gel is high in rebound resilience and good in surface touch feeling, and the silica gel protective sleeve has a good buffering and anti-falling protection effect on the hard disk.

Description

technical field [0001] The invention relates to the field of silica gel, in particular to a silica gel protective cover for a mobile storage hard disk and a preparation method thereof. Background technique [0002] As an external data storage device, mobile storage hard disks are widely used in the field of calculators. Since the internal structure of the hard disk is easily damaged when it is collided, it is easy to cause damage to the stored data. Therefore, most solid-state mobile storage hard disks are generally stored in The casing is covered with a protective cover, and the protective cover of the mobile storage hard disk is mostly made of silicone material. The silicone material has good elasticity and certain viscosity, which can play a shock-proof and anti-slip effect on the hard disk. [0003] At present, the single-layer thickness of the hard disk silicone protective cover on the market is mostly between 1-2mm, which can have a good heat dissipation effect, but th...
