Do you know the filler masterbatch? If you are a manufacturer of filler master batch or a friend interested in filler master batch, then follow the footsteps of Sainuo. Today’s article will surely let you gain a lot.
1. Adding effect of EBS in filling masterbatch
Ethylene Bis-stearamise (EBS) is added to the filler masterbatch. Because EBS has good wetting and dispersing effect, it has good coating property for inorganic filler, improves the dispersion quality of filler, helps to increase the content of filler, reduce the amount of carrier resin and additives, and reduce the production cost; Good lubrication effect, improve the production efficiency of products, reduce equipment wear and prolong the service life of equipment.

2. What should the filler be treated with high filling masterbatch?
Due to the high content of filler contained in the high filling masterbatch, the surface of calcium carbonate needs to be treated during the preparation process. Generally, polyethylene wax , app, etc. are commonly used for surface treatment to improve its wettability and dispersion, reduce agglomeration, and improve its fluidity and mechanical properties.
3. Selection of additives in polyolefin filling masterbatch
The additives used in polyolefin filling masterbatch mainly include dispersant and surface treatment agent. The function of dispersant is to improve the processing fluidity of masterbatch and make it more evenly dispersed in the matrix resin. Polyethylene wax is commonly used as dispersant to wet and disperse the powder. Surface treatment agents can change the surface activity of inorganic fillers from hydrophilic to lipophilic, so as to facilitate mixing with carrier resins, mainly including coupling agents and stearic acid.

4. How to solve the agglomeration of calcium carbonate particles in the filling masterbatch
To solve the agglomeration problem of calcium carbonate particles, attention should be paid to two aspects: first, excessive friction should be prevented during surface treatment. Once static electricity is generated due to friction, agglomeration will easily occur; Secondly, the amount of surface treatment agent should be sufficient. When the surface of particles is changed to lipophilic by the action of coupling agent, the surface energy will be greatly reduced, and it is not easy to reunite with each other.
5. Reasons for frequent screen change during the production and processing of filling masterbatch
The frequent screen change during the processing of filling masterbatch greatly affects the processing efficiency. The reason for this phenomenon may be that the mesh number of calcium powder selected is not up to standard; Or the dispersing effect of the lubricating dispersant is poor, resulting in the failure to open the agglomerated calcium powder, causing the filler to block the network; It is also possible that the raw materials are affected by moisture, and the agglomeration phenomenon occurs in the process of production and processing, resulting in the blocking of the net.
6. Surface activation modification of filler in filler masterbatch
There is incompatibility between filler and resin in the filling masterbatch. For the production of high-quality and high filling masterbatch, it is the key to solve the compatibility between filler and resin. The powder coating agent produced by Sano has a strong affinity for inorganic powder, which can greatly improve the compatibility of system components, and has the effects of coupling, dispersion, brightness and compatibilization. It has a good wetting and coating effect on the powder, and effectively prevents the second agglomeration of the powder.
