Butyl rubber is a type of synthetic rubber synthesized from isobutene and a small amount of isoprene. The finished product is not prone to air leakage and is generally used to manufacture tires. Butyl rubber is a copolymer of isobutene and isoprene, which was put into industrial production in 1943.
Butyl rubber, abbreviated as IIR, is the abbreviation for Isobutylene Isoprene Rubber. Has good chemical and thermal stability, with the most outstanding being airtightness and water tightness. Its air permeability is only 1/7 of natural rubber and 1/5 of styrene butadiene rubber, while its steam permeability is 1/200 of natural rubber and 1/140 of styrene butadiene rubber. Therefore, it is mainly used to manufacture various rubber products such as inner tubes, steam tubes, water tires, dam bottom layers, and gaskets.
Structural characteristics
Industrial kneading machines generally use a through chassis for easy installation. The industrial kneading machine adopts helical gears or hard tooth surface reducers, which ensure smooth transmission with the main engine, low noise, and long service life. The mixing blades and inner walls of the mixing tank are made of SUS304 stainless steel or SUS316L stainless steel to ensure the purity of the products. The shaft seal structure and sealing effect are good. Designed a vacuum box balance structure to ensure that no black material is ground out. Integrated electrical control (host operation, hydraulic cylinder flipping, hydraulic cover opening, and constant temperature control) and temperature control and display for easy operation and process control.

The Z type vacuum kneader mixer in a small laboratory is an efficient mixing equipment designed for high viscosity and high elastic-plastic materials (such as silicone rubber, butyl rubber, hot melt adhesive, sealant, chewing gum, etc.) in the research and development and small-scale testing stages. It integrates mixing, kneading, and defoaming, and has the characteristics of compact structure, precise operation, and strong sealing. It is widely used in new materials, chemical industry, food, medicine, and electronic packaging fields.
Core structure and working principle
Z shaped mixing blade design
A pair of Z-shaped or ∑ - shaped stirring blades are used to rotate in opposite directions at different speeds (main shaft 20-40 RPM, secondary shaft 10-20 RPM) in a W-shaped mixing tank, forming strong shear, stretching, folding, and compression effects to achieve deep kneading and uniform dispersion of materials.
Vacuum defoaming system
Equipped with a vacuum pump, the working vacuum degree can reach ≤ -0.094 MPa (about -0.1 MPa), effectively removing bubbles and volatile matter trapped in the material during the mixing process, significantly improving the density, transparency, and mechanical properties of the final product. Especially suitable for materials such as HTV silicone rubber and neutral glass adhesive that require high air tightness.
Temperature control system
The mixing tank has a jacket structure and supports electric heating, thermal oil heating, or water cooling. The temperature control accuracy can reach ± 2 ℃, ensuring stable and controllable reaction process. Some high-end models have multi zone independent temperature control function to meet complex process requirements.
Sealing and Material Safety
The mixing shaft adopts a vacuum sealed structure to prevent filler particles from entering the cylinder body and ensure material purity
