Abstract

The invention discloses a heat-conducting buffer mixed rubber sleeve as well as a preparation method and application thereof. The mixed rubber sleeve is made of zinc oxide, copper powder, tungsten powder and nano-silicon nitride alloy material, and then mixed with glucose for high-temperature carbonization. After the alloy / porous carbon composite material is added, the stability of the glue is improved. Avoid metal agglomeration and deposition, causing uneven structure and cracks. Compared with the prior art, the present invention avoids the use of expensive silicone rubber, and improves the disadvantages of other rubber components by using metal materials and porous carbon, thereby obtaining a low-cost, high-performance rubber-mixed sleeve that meets the needs of production and life .

Description

technical field [0001] The invention belongs to the technical field of rubber sleeve preparation, and in particular relates to a heat-conducting cushioning mixed rubber sleeve and a preparation method and application thereof. Background technique [0002] Rubber has a certain elasticity and can rebound after being hit. Therefore, it is used in many electronic fields to protect small components, such as thermistors. The structure of the thermistor is simple. In the prior art, a protective cover is usually added at the position of the crystal, which can prevent the thermistor from being damaged during the collision of the electrical appliance. [0003] Smoked sheet rubber and butadiene rubber are commonly used rubber materials. They are used alone as the main component to prepare protective sleeves. They are not resistant to breakdown and have low thermal conductivity. The overall performance needs to be improved. Therefore, it is necessary to develop a rubber-mixed material ...
