Embodiment 1
[0025] The composite formula glue is prepared according to the mass ratio of polyurethane glue, titanium oxide powder, silicon oxide powder, and propanol at 10:30:30:50. During the preparation, ultrasonic oscillation and electromagnetic stirring are assisted in the heating function to make the composite glue mix evenly , The temperature is controlled at around 60°C for preheating.
[0026] In high-temperature equipment at a temperature of 100°C to 200°C, under the condition of nitrogen protection (nitrogen and oxygen content 50ppm), use a vertical automatic spray gun to evenly spray the polyester / nylon close-woven fabric after cleaning the compound formula glue for 10 seconds, then cool down and dry , the sprayed polyester / nylon close-woven fabric enters the roller device for extrusion at a temperature of 20°C to 100°C, and the roller pressure is 0.1MPa to 0.6MPa. Afterwards, the polyester / nylon densely woven fabric is cooled to normal temperature and sewed into a hot air ball...
