Problems solved by technology

Although new technologies such as lasers, ultrasonic waves, and microwaves have been developed successively, infrared technology has remained in the mainstream for quite a long time.
Its defects are manifested in the aspects of easy aging of equipment, short service life, high false alarm rate, and inability to prevent curve perimeters.
Although the popular needle camera is relatively invisible, it is especially suitable for military detection applications, but it is greatly affected by high magnetic radiation and nuclear radiation, and basically loses its detection function
However, the perimeter protection system of electronic fence detectors has a low false alarm rate and strong deterrent and deterrent power, that is, the police will call the police before the criminals break in through the wall. difficulty

Abstract

The invention discloses a concealed theft-proof latex paint and a preparation method thereof. The latex paint consists of deionized water, cellulose, dispersant, wetting agent, defoaming agent, black silicon wafer powder, pigment and filler, preservative, defoaming agent, polyacrylic emulsion, pH adjusting agent and thickening agent. The latex paint has the advantages of clear thermally-formed image, high sensitivity, good vibration resistance and the like, is not affected by environments (such as electromagnetic radiation, nuclear radiation, illumination and the like), and can keep better performance under the climatic conditions of fog, rain, snow and the like; the thermally-formed image has good concealed protection; the latex paint can be displayed without image in a visible light range, complements the prior theft-proof art, is directly brushed or sprayed on the wall as common latex paint, and can be used for key theft-proof sections of curve boundary; and the latex paint has the advantages of convenient construction, low cost and long theft-proof property, does not need any maintenance cost, and does not need any power supply equipment.

Description

technical field [0001] The invention relates to a concealed anti-theft latex paint applied to buildings and a preparation method thereof. technical background [0002] With the development of science and technology, the technical application of anti-theft alarm has developed from relying on wire fences to the popular infrared imaging technology in the new era. Although new technologies such as lasers, ultrasonic waves, and microwaves have been developed successively, infrared technology has remained in the mainstream for a long period of time. Its defects are manifested in the aspects of easy aging of equipment, short service life, high false alarm rate, and inability to prevent curve perimeters. Although the popular needle camera is relatively invisible and is especially suitable for military detection, it is greatly affected by high magnetic radiation and nuclear radiation, and basically loses its detection function. However, the perimeter protection system of electronic...
