Background
The medical isolation and protection composite material is a fabric for manufacturing isolation and protection clothes, and plays a role in isolating pathogens or medical pollutants and protecting the safety of users.
Generally, medical barrier composite materials, in order to ensure barrier function, cause a reduction in their breathability, and users feel stuffy and uncomfortable when wearing protective garments made of these materials. In addition, these materials may also break during use due to stretching or impact, presenting a certain risk to the user. Therefore, how to improve the ventilation effect and have high strength while ensuring the isolation effect becomes an urgent problem to be solved.

In the multilayer composite material, the square meter gram weight of the SMMS cloth is 30g/m2。
In the multilayer composite material, the square meter gram weight of the TPE903 is 3g/m2。
In the multilayer composite, the breathable film has a grammage of 25g/m2。
In the multilayer composite material, the square meter gram weight of the SS PP non-woven fabric is 15g/m2。
A preparation method of the multilayer composite material comprises the following steps:
(1) preheating and heating the TEP903, and bonding the SS PP non-woven fabric and the breathable film together; standing for 72 hours for curing to obtain a semi-finished product;
(2) and adhering SMMS cloth outside the semi-finished breathable film by using the preheated and heated TEP903, standing for 72 hours, and curing to obtain the finished product.
In the preparation method, the TEP903 is preheated and heated by adopting an online hot melt adhesive compounding device, and the TEP903 is sprayed into a fine-thread fog shape by a micropore nozzle along with hot air of 0.35 MPa under the pressure of 0.55 MPa after being melted.
In the preparation method, the preheating temperature of the TEP903 is 140 ℃, and the preheating time is 60 min.
In the preparation method, the heating temperature of the TEP903 is 155 ℃.
In the preparation method, the diameter of the micropores of the micropore nozzle is less than 0.01 mm.
The invention has the beneficial effects that: the hot melt adhesive TEP903 is sprayed into a fine-thread fog shape through reasonable collocation of temperature and pressure, the spraying diameter is smaller than 0.01mm, the fog-shaped polymer adhesive combines the breathable film and the SMMS cloth together, and the protection of the surface layer PP non-woven fabric ensures that the overall performance of the material is sublimated, thereby ensuring that the basic physical performance of the composite material is not damaged after the composite, simultaneously ensuring that the multilayer composite material is more uniform in compounding, having double barrier property and double air permeability, and being applicable to germ isolation, operating rooms and laboratories.
