AI Technical Summary

Technical Problem

Existing police interception equipment cannot effectively solve the problem of people inside vehicles being able to see police officers, while police officers cannot see the situation inside the vehicle, leaving law enforcement officers in an unknown threat and the risk of handling the situation has not been reduced.

Method used

An automotive anti-visual-impedance spray was prepared using acrylate copolymers and modified carbon black powder. Through chemical bonding and molecular-level intercalation, a dense visual-impedance film layer was formed, blocking the view of occupants inside the vehicle.

Benefits of technology

It can quickly form a visual barrier, reduce the ability of people inside the vehicle to observe the outside world, improve law enforcement safety, reduce casualties and traffic losses, is easy to clean and restore to its original state, is flexible in use, and reduces law enforcement costs.

Abstract

The application relates to the technical field of aerosol, and particularly discloses a car search blocking visual jetting agent and a preparation method thereof. In the car search blocking visual jetting agent, the preparation raw materials of the car search blocking visual jetting agent include acrylic ester copolymer, modified carbon black powder, thickening agent, solvent, first propellant and second propellant; the preparation raw materials of the acrylic ester copolymer include long-chain alkyl acrylate, acrylamide and 2-hydroxyethyl methacrylate phosphate, and the mass ratio of the long-chain alkyl acrylate, the acrylamide and the 2-hydroxyethyl methacrylate phosphate is (40-48):(3-5):(2-4). After jetting, the car search blocking visual jetting agent can form effective shielding in the area of the front windshield within 3 seconds, can improve the adhesion of the blocking visual jetting agent, and can ensure the durability of the visual suppression effect.
