High energy-gathered composite dust retarding material for modified obstructive dust as well as preparation method and application

Abstract

The invention discloses a high energy-gathered composite dust retarding material for modified obstructive dust as well as a preparation method and application. The composite dust retarding material is prepared from a surfactant fiber layer, a polypropylene electrostatic fiber layer and a polytetrafluoroethylene fiber layer according to the sequence of a surface layer, a middle layer and an inner layer by using an ultrasonic laminating technology, wherein the surfactant fiber layer is formed by spraying sodium alkyl sulfate and derivatives thereof, sodium silicate and derivatives thereof, betaine and derivatives thereof or sodium aluminate and derivatives thereof on the surfaces of polypropylene fibers; the composite dust retarding material and a product prepared from the surfactant fiber layer modify inorganic respirable dust into inorganic obstructive dust; or the surfactant fiber layer is formed by spraying sorbitol and derivatives thereof, alkyl glycoside and derivatives thereof, carboxylate and derivatives thereof or cassava starch and derivatives thereof on the surfaces of polyester fibers; the composite dust retarding material and a product prepared from the surfactant fiber layer modify organic respirable dust into organic obstructive dust.

Description

technical field [0001] The invention relates to a high-energy composite dust-blocking material for modifying obstructive dust, its preparation method and application, in particular to a high-energy composite dust-block capable of modifying "respirable dust" into "obstructive dust" Materials and their preparation methods and applications. Background technique [0002] Pneumoconiosis is the most serious and widespread occupational disease in my country at present. It is an irreversible and irreversible disabling disease. The direct cause of pneumoconiosis is that dust-exposed personnel inhale "respirable dust" and retain it in the lungs. Cause macrophage pneumonia, dust cell granuloma and dust-induced pulmonary fibrosis. In addition, other respiratory diseases such as metal and its compound pneumoconiosis, chronic obstructive pulmonary disease caused by irritating chemicals, and hard metal lung disease endanger human health. Even severe weather such as smog can bring various ...

AI Technical Summary

Problems solved by technology

When the dust diameter is 5-10 μm, it can reach the tracheal wall of the human body, and the dust diameter below 5 μm can reach the alveolar area (non-ciliated respiratory bronchioles, alveolar ducts, and alveolar sacs). This kind of dust is extremely harmful to the human body. But when the diameter of the dust is more than 10 μm, it can only reach the nasopharynx of the human body.
