Medical barite protective clothing material and preparation method thereof

Abstract

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. The barite medical protective clothing material provided by the invention is composed of an isolating layer and an outer protective layer, the thickness of the isolating layer is 190-300 [mu] m, and the thickness of the outer protective layer is 150-230 [mu] m; the preparation method comprises the following steps: physically purifying barite and grinding into powder; uniformly kneading the barite fine powder and polyethylene according to a weight ratio of 3.5: 6.5 or 4: 7.5, and carrying out hot press molding to obtain an isolating layer non-woven fabric; and carrying out hot rolling compounding on the isolating layer non-woven fabric and the polypropylene spunbond non-woven fabric to obtain the barite medical protective clothing material. The material has the advantages of good anti-radiation performance and low preparation cost, has good air permeability and moisture permeability, and can be repeatedly used after being washed and disinfected.

Description

[0001] This application is a divisional application with an application date of October 8, 2017, an application number of 201710926767.0, and an invention title of "A barite medical protective clothing material and its preparation method". technical field [0002] The invention belongs to the technical field of medical protective clothing materials, and in particular relates to a barite medical protective clothing material and a preparation method thereof. Background technique [0003] In recent years, with the development and rapid popularization of advanced X-ray diagnosis, cardiovascular angiography and angioplasty, interventional radiotherapy has been widely carried out. In fine operations such as cardiovascular angiography and angioplasty, medical radiologists must be exposed to X-ray fields for a long time. If the body is continuously or intermittently exposed to X-rays for a long period of time and reaches a certain dose, the cells in the tissue will be inactivated by...

Problems solved by technology

[0005] With the rapid development of non-woven fabrics, medical surgical gowns are also changing with each passing day. Non-woven fabrics such as anti-stick fabrics, spunlace fabrics, SMS composite fabrics and flash steaming have emerged as the times require. They also have their own advantages and disadvantages when applied to medical surgical gowns. Adhesive cloth has poor air permeability, texture, low hydrostatic pressure, and poor protection, but the price is relatively cheap, so anti-adhesive cloth is the main non-woven fabric for surgical gowns in my country

Usually, in order to achieve the protective effect, the surgical gown fabric is usually laminated or laminated, which is thick and has very poor air permeability; the spunlace cloth is most like a traditional woven fabric, soft and has good drapability, but the spunlace technology is limited. There are not many spunlace nonwovens used for surgical gowns. Spunlace surgical gowns are generally imported from abroad, and the price is very high, so few hospitals in China use spunlace surgical gowns; SMS nonwovens have good protection performance and strong strength. The wear resistance is also good, but the cost of online composite SMS is high, and the hand feel is also poor; the flash cloth has good filtration performance, but it is very uneven, and only DuPont and Asahi Kasei, which have monopoly technology, can do it, and the price is very low. high
