3-5 parts of silicone oil, nanometer Au28(SCH3)200.5-1 parts of cluster；
The coating processes include the following steps：
(1) preparation of coating：All raw materials addition high-speed mixer and mixing is uniform, room temperature mixing, incorporation time 3-5min；
Batch mixing is added after screw extruder melt blending and extrudes, be granulated through die head, it is spare that coating particles are made；
(2) preheat：Braiding base fabric is put into baking oven and is preheated；
(3) spray：Coating particles prepared by step (1) add material-spraying device, and coating is under the injection of spraying machine to warp
The braiding base fabric for crossing preheating carries out material spray；
(4) post-process：The braiding base fabric completed to spraying is cooled down, is dried, and the braiding base fabric after drying carries out electrostatic
Eliminate, the braiding base fabric after static elimination is wound, is woven into bag.
The anti-aging master batch by nano imvite, rutile type nano titanic oxide, septichen phenyl ester according to
Mass ratio is 10：4-6:1-2 is made through melt blending, extruding pelletization.
It is 210-215 DEG C that step (1) the melt blending technological parameter, which includes die temperature, melt temperature 245-275
DEG C, screw speed 260-300rpm/min, feeding machine speed is 25-45rpm/min.
Step (2) the oven for drying temperature is 100 DEG C -120 DEG C, drying time 5-7min.
The coating thickness of step (3) spraying is 110-130um.
Beneficial effects of the present invention：
The sprayed coating that the present invention uses is a kind of Novel environment-friendlymaterial material, is sprayed on the inside of woven bag base fabric, has coating
Fine and close, continuous, jointless feature, make the woven bag produced have good mobility, corrosion resistance, heat-resisting quantity and compared with
Good processing performance, makes coating woven bag have the characteristics that intensity is high, quality is good, cheap, durable, can wrap automatically
Used on wiring；Woven bag coating processes provided by the invention, to spray as major technique, not only technique is simple for this method, sets
Standby less investment, production efficiency are high, and are conducive to environmental protection.
