The frequent generation of portion's war, natural calamity etc. causes disease and wound to become the haze that the mankind can't get rid of forever.As the modern times
The important foundation and component part of the important means of medicine --- medical instrument, biomaterial for disease diagnosing and treating,
Reparation, replacement or the function of histoorgan are promoted, and making largely to struggle rehabilitates in the sufferer at residual, dead painful edge.In recent years,
Global medical instrument industry high speed development, average annual growth rate are same period increasing speed of national economy more than 2 times, are known as " rising industry ",
Have become the 21st century very active new source of economic growth.By taking China as an example, China's Medical Device Market speedup height in 2010
Up to 23%, market scale breaks through 1,00,000,000,000 yuan of high pointes for the first time, becomes the second-biggest-in-the-world Medical Device Market for being only second to the U.S.,
Expecting market scale in 2015 will be close to 3,40000000000 yuan.Just because of the so huge society of biomaterial and economic value,
Its R&D work is increasingly subject to the highest attention of countries in the world government, industrial circle and scientific and technological circle, successively by beauty, moral, day, Australia and
The Chinese government is included in high-tech key new material development plan.In presently used biological medicine material, suppression itself can be played
The material of bacterium effect has had many researchs and application, but the material that can play sterilizing is actually rare, while
The material that medical industry is used has special requirement under conditions of special, if membrane material needs good permeability, no
Atomizing effect can be generated because of the change of temperature, affect normal use.
Therefore, to solve the above problems, providing a kind of new technical solution.
Summary of the invention
The present invention provides a kind of preparation method of sprayed film.
The technical solution adopted by the present invention is that:
A kind of preparation method of sprayed film, comprising the following steps:

It closes uniformly, obtains material a；
Material a is transferred in reaction kettle by step b, and melamine and hydroxypropyl methyl cellulose is added, and is added under condition of negative pressure
Heat stirs 10-15 minutes to 65-70 DEG C, obtains material b；
Antioxidant, barium stearate and sodium benzoate are added in material b, is uniformly mixed, obtains material c by step c；
Step d, by material c in double screw extruder extruding pelletization, obtain master batch, by master batch using plastic film blowing machine extrusion blow
Film obtains the preventing atomization medical films with sterilization functions.
Further, the PVC, active aluminium hydroxide, lecithin, titanium dioxide and high density polyethylene (HDPE) parts by weight difference
Are as follows:
30-40 parts of PVC；
10-15 parts of active aluminium hydroxide；
5-10 parts of lecithin；
