Problems solved by technology

There are millions of workers engaged in mercury-related industries in my country, and when workshop workers produce and transport corresponding products in high-mercury industry workshops, such as thermometers, barometers, fluorescent lamps, and batteries in the electrical industry, workshop workers and their clothes will inevitably be damaged. If the mercury thermometer is broken during the process of carrying the mercury thermometer, this part of mercury directly enters the human body through the skin, causing great harm to the body of the workshop workers

Abstract

The invention discloses a composite material and a preparation method thereof. The composite material is formed by laminating, successively from top to bottom, a barrier layer, a nano-selenium composite material layer, a water-absorbing layer, and a contact layer; wherein the barrier layer is a rubber-plastic waterproof material; the nano-selenium composite material layer is a nano-composite and includes, by mass, 70-90% of nano-active carbon, 5-10% of nano-selenium and 5-20% of a hot melt adhesive; the water-absorbing layer is made from a cellulose water-absorbing material; and the contact layer is made of any one of cotton cloth, nonwoven fabric and linen cloth. The composite material has excellent water-absorbing function, permeability and barrier performance, has strong capture effecton mercury, effectively prevents direct contact between liquid mercury and mercury vapor and skin of workers in mercury industry or avoids re-volatilization of the liquid mercury on clothes. The composite material can guarantee body health of workers in high-mercury industry and has great social and economic benefits.

Description

technical field [0001] The invention relates to a composite material and its preparation method and application. Background technique [0002] There are many mercury-related industries in my country, such as chemical industry, electrical industry, metallurgical casting, medical industry, military industry and other industries. There are millions of workers engaged in mercury-related industries in my country, and when workshop workers produce and transport corresponding products in high-mercury industry workshops, such as thermometers, barometers, fluorescent lamps, and batteries in the electrical industry, workshop workers and their clothes will inevitably be damaged. If the mercury thermometer is broken during the process of carrying the mercury thermometer, this part of mercury directly enters the human body through the skin, causing great harm to the body of the workshop workers. [0003] Therefore, there is an urgent need to develop composite materials that can prevent l...
