Abstract

The invention discloses carbon nanotube silicone rubber. The carbon nanotube silicone rubber is composed of the following components, in parts by weight: 6-10 parts of siloxane, 1-10 parts of borate,3-6 parts of high-quality carbon black, 1-3 parts of copper powder, 1-3 parts of titanium oxide, 3-6 parts of titanium dioxide, 1-10 parts of ethyl orthosilicate, 4-8 parts of phthalate, and 1-2 partsof carbon nanotubes. A preparation method of a novel glass curtain wall sealant comprises the following steps: mixing the components according to the above ratios, and performing stirring for uniformdispersion to obtain the finished product. Compared with the prior art, the sealant provided by the invention has excellent performance such as heat resistance, aging resistance, stress resistance and corrosion resistance, the Tg is lower than -60 DEG C, and the sealant has fairly good low-temperature resistance, good elasticity, and great application prospects.

Description

technical field [0001] The invention belongs to the technical field of adhesives, in particular to carbon nanotube silicone rubber. Background technique [0002] Sealant is a sealing material that deforms with the shape of the sealing surface, is not easy to flow, and has a certain degree of cohesion. It is an adhesive used to fill the configuration gap and play a sealing role. According to the base material, it is divided into rubber type, resin type, and oil type. Basic type, some sealants have poor bonding performance and poor sealing performance. They are easy to harden and crack when the outdoor temperature is low in winter, and produce harmful substances during and after curing, and even pollute the substrate. Glass curtain walls are widely used, mainly for decoration and other purposes. When the glass curtain wall is in use, it needs to be spliced ​​and sealed, otherwise it will easily cause safety hazards. Carbon nanotubes, also known as bucky tubes, are one-dimens...
