AI Technical Summary
Technical Problem
The existing anti-fingerprint agent cannot cure at room temperature, and has poor friction resistance and cannot effectively adhere to substrates that are not resistant to high temperatures.
Method used
Perfluoropolyether siloxane is used, and its molecular structure contains tertiary amine bonds, which can be cured at room temperature, improving adhesion and friction resistance. This material enhances the performance of the anti-fingerprinting agent by grafting three molecules of siloxane groups on the perfluoropolyether.
Benefits of technology
The anti-fingerprint agent is cured at room temperature, which improves adhesion and friction resistance, reduces production costs, and simplifies the production process.

Abstract
The invention discloses a perfluoropolyether siloxane and a preparation method and an anti-fingerprint agent, and belongs to the field of anti-fingerprint agents. First, a perfluoropolyether intermediate containing an epoxy group is prepared, and then reacted with a secondary aminosiloxane and a haloalkylsiloxane in sequence to obtain a perfluoropolyether siloxane containing a tertiary amine bond. Due to the presence of the tertiary amine bond, the perfluoropolyether siloxane can effectively reduce the curing temperature, thereby achieving the purpose of curing into a film at room temperature. In addition, after being configured into an anti-fingerprint agent, it can act on the surface of a substrate of different materials and cure to form a film, and at the same time has excellent anti-fingerprint, friction resistance and other properties. The preparation method is simple to operate, mild in conditions, and has broad application prospects.
