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.

Embodiment 1
[0051] A high-energy-gathering composite dust-blocking material for modifying barrier dust is prepared by the following method:
[0052] (1) Preparation of surfactant solubles: After heating water to 30-50°C, add surfactants to the water and stir for 30 minutes; then add adhesive, continue stirring for 30 minutes to obtain surfactant solubles;
[0053] The addition of described water is 2.5 times of surfactant;
[0054] The addition of the adhesive is 0.3wt% of the surfactant;
[0057] (2) Preparation of surfactant fiber: the surfactant solution obtained in step (1) is prepared according to 5g / m 2 The ratio is evenly sprayed onto the surface of polypropylene fibers to obtain surfactant fibers;
[0058] (3) Preparation of high-energy composite dust-proof material: Put the surfactant fiber, electrostatic fiber a...

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 polytetrafluoroethylenefiber 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 sodiumalkylsulfate and derivatives thereof, sodiumsilicate and derivatives thereof, betaine and derivatives thereof or sodiumaluminate 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, alkylglycoside 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 cellgranuloma 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 metallungdisease endanger human health. Even severe weather such as smog can bring various ...
