With performance uniformity.Requirement to calendering process is that speed is fast, high production efficiency, low energy consumption.Calendering process is to glue stuff compounding
There is decisive influence with the quality of finished product.
Solution polymerized butadiene styrene rubber is widely used in the fields such as tire, adhesive tape, sebific duct.It is filled out what solution polymerized butadiene styrene rubber wet process was kneaded
In material, phyllosilicate composite material, form factor is than high, intensity is high, heat-resist, air-tightness compared with traditional gum filler
It is good.During the preparation process, the selection of filler has the function of key, while the partial size of filler to the intrinsic performance of the rubber of formation
It is also important influence factor with hybrid mode, the excessive filler of partial size is difficult to play reinforcing and modifying function well, instead
It will affect the performance of rubber.The too small filler of partial size then easily causes reunion, poor dispersion.Due to presently used filler
Bioblast diameter it is often smaller, large specific surface area is easily reunited, be difficult to so as to cause it is evenly dispersed, to limit it
Reinforcing effect.It is mainly prepared by way of filler addition-stirring-dispersion-cohesion at present, wherein filler is in rubber
Influence of the degree of scatter to final performance in solution is very big, and currently used mode has and will stir resulting mixture and pass through
One nozzle sprays in the case where high pressure high shear, and above-mentioned ejecta is made to make mixed liquor in Guan Zhongyu by swan neck more than one
Tube wall hits the dispersibility for increasing filler and additive, but the above method obtains and is suitable for small-scale experimental study, is producing greatly
It is difficult to realize in amount production.There is presently no mature effective, suitable for large-scale industrial production preparation methods.
