Preparation Method Of Waterborne Polyurethane Adhesive

< p > the invention discloses a polyurethane adhesive with < a href= "http://www.91se91.com/news/index_c.asp" > water < /a > polyurethane, including waterborne polyurethane, defoamer, leveling agent, wetting agent, filling agent and antioxidant. The defoamer is polyethylene glycol ether, and the leveling agent is Polymethylphenyl siloxane, the wetting agent is two methyl sulfoxide, and the filler is diatomite, and the antioxidant is 2, 6- three grade butyl -4- methylphenol.

< /p >

< p > the product is made of five kinds of additives: waterborne polyurethane and < a href= "http://www.91se91.com/news/index_c.asp" > defoamer < /a > leveling agent, < a href= > http://www.91se91.com/news/index_c.asp > wetting agent > /a > filler and antioxidant. The adhesive has the characteristics of high viscosity strength, good water resistance, long storage time, high temperature resistance and good use effect.

< p > as a special training college for textile talents, Shang Gang, Secretary of the Party committee of Wuhan Textile University, introduced the 3 support for the differential development of schools.

First of all, relying on industry associations, we should use the industry development plan to guide the strategic thinking of running schools, aim at technological innovation in the industry, and maintain close ties between school teaching and industry development.

Secondly, relying on leaders to achieve scientific breakthroughs, attracting talents from home and abroad through the national "1000 person program", and through the training within the school, the formation of their own talent team.

Finally, depending on the characteristics of the industry and the needs of enterprises, we will develop the projects of industry, University and research.

After listening to the report of Shang Gang, Chen Shujin praised the school's research system of combining production, teaching and research, and encouraged the school to open up the last mile of the pformation of scientific research achievements. P

Xu Weilin, director of the National Key Laboratory of new textile materials and advanced processing technology, director of P, reported to the inspection team the progress of basic research on particle flow in-situ dyeing technology and equipment.

In order to overcome the shortcomings of traditional dyeing and the low utilization rate of dye solution, Xu Weilin led research and development personnel to start the research and development of particle flow in-situ dyeing technology.

< p > the project uses ultrasonic equipment to atomization into floating particles, and then sends particles to the dyed fabric through the control of fluid. "This method will not cause the phenomenon of deviation in dyeing, but also ensure the use of fuel 100%."

Xu Weilin said that in the later work plan, the optimization of atomization equipment structure, the use of multi color atomization, through atomization of particles to form a new color will become the focus of work.
