Security equipment protective materials

Abstract

The invention relates to a protective material for a security inspection device. The protective material comprises the following ingredients by weight part: 20-50 parts of aluminum powder, 3-8 parts of silver powder, 5-12 parts of lead powder, 15-30 parts of pvc rubber, 4-8 parts of sodium succinate, 7-14 parts of silica sand, 2.5-5.5 parts of boron carbide, 2-4 parts of bismuth oxide, 1-2 parts of silicon phosphide, 1.5-8.5 parts of silicon nitride, 3-6 parts of polyethylene, 5-7 parts of polyolefin, 0.5-2 parts of polyester, 1.5-1.8 parts of cosolvent, 2-6 parts of molybdenum oxide, 2-8 parts of potassium oxide and 2-10 parts of ferric oxide.

Description

technical field [0001] The invention relates to the technical field of human body safety inspection detector equipment, in particular to protective materials for security inspection equipment. Background technique [0002] In recent years, public security issues have increasingly attracted the attention of people all over the world, and higher requirements have been put forward for the reliability and intelligence of anti-terrorism, security detection and public security investigation systems. There are metal security gates, hand-held metal security detectors, luggage security detectors, millimeter wave security detectors and back scattered security detectors at home and abroad. [0003] The first-generation security inspection products are represented by metal security doors and hand-held metal security detectors. This type of equipment detects metal objects through magnetic field technology, and can only detect metal objects, and cannot effectively distinguish and detect n...

AI Technical Summary

Problems solved by technology

[0003] The first generation of security inspection products are represented by metal security doors and hand-held metal security detectors. This type of equipment detects metal objects through magnetic field technology, and can only detect metal objects, and cannot effectively distinguish and detect non-metal objects.

No imaging system, unable to locate suspicious objects

[0004] The second-generation security inspection products are represented by luggage security detectors, millimeter wave security detectors and back-scattered security detectors. Among them, luggage security detectors use high-dose X-ray irradiation to clearly detect suspicious objects in luggage, which is fast and extremely large. It changed the current situation of security inspection at that time, but with the improvement of criminal methods, this type of equipment cannot be used for human inspection due to dose and design reasons

[0005] At present, the dose of this type of equipment has always been at the safe node of the acceptable dose for the human body, and the electromagnetic radiation of millimeter waves will destroy the bioelectric field of the human body, which will affect heart patients with pacemakers, and there is a huge potential safety hazard
