Description
The application is a divisional application with application date of 2017, 10 and 08, application number of 201710926767.0 and invention name of barite medical protective clothing material and a preparation method thereof.
Technical Field
The invention belongs to the technical field of medical protective clothing materials, and particularly relates to a barite medical protective clothing material and a preparation method thereof.
Background
In recent years, radiological intervention has been widely performed with advanced X-ray diagnosis, development and rapid popularization of angiocardiography and angioplasty. In the fine operation of cardiovascular angiography and angioplasty, the medical radiologist needs to be exposed to the X-ray field for a long time. If the body is continuously or intermittently exposed to X-rays for a long time and reaches a certain dose, cells in the tissue are inactivated by ionizing radiation, thereby causing radioactive damage, such as hematopoietic tissue damage, and even causing leukemia, skin cancer, etc. If the eye is exposed to overdose radiation for a long time, the eye can cause lens lesion and generate radiation cataract.
The research on medical X-ray protection is mostly limited to walls, building materials, baffles of medical equipment and the like, the attention on the protective equipment of medical staff is less, and due to reasons such as cost and the like, most medical units cannot use protective clothing with better protective performance, and the protective clothing is disposable under special conditions, so that the resource waste is caused, the cost is high, and the health safety of the medical staff is difficult to ensure. Early medical X-ray protective clothing generally used lead as a shielding material, and because of heavy weight and hard texture, muscles of the back and the waist of medical radiology workers are tired and even damaged, and the medical radiology workers are expensive and easy to cause lead poisoning. Under the development trend, how to protect medical staff from various rays is particularly important.
With the rapid development of the non-woven fabric, medical surgical gowns are also different day by day, the non-woven fabrics such as the anti-sticking fabric, the spunlace fabric, the SMS composite fabric and the flash evaporation fabric are produced, and the anti-sticking fabric has the advantages and the disadvantages when being applied to the medical surgical gowns, is poor in air permeability, texture, low in hydrostatic pressure and protection performance and low in price, so that the anti-sticking fabric is the main non-woven fabric for manufacturing the surgical gowns in China. Generally, in order to achieve a protective effect, the fabric of the surgical gown is subjected to lamination or laminating treatment, so that the fabric is thick and has very poor air permeability; the spunlace fabric is most like a traditional woven fabric, is soft and has good drapability, but the spunlace technology is limited, the spunlace non-woven fabrics used for the surgical gown are few, and the spunlace surgical gown is generally imported from abroad and has high price, so that few hospitals use the spunlace surgical gown in China; the SMS non-woven fabric has good protective performance, strength and abrasion resistance, but the online composite SMS has high cost and poor hand feeling; the flash cloth has good filtration performance, but is very uneven, and is only available from dupont and asahi chemical companies with monopoly technology, which is very expensive.
