Description
Technical Field
The invention relates to the field of chemical industry, and particularly relates to a foaming master batch and a preparation method thereof.
Background
The foaming process produces dust flying during direct use, which pollutes the environment and damages health. Meanwhile, the foaming is directly mixed in the resin matrix, and the reinforcing effect of the foaming on the resin cannot be fully exerted due to factors such as uneven dispersion, poor interface bonding and the like. These all affect the use of foaming.
Therefore, the foaming is usually carried out by banburying and granulating in advance. In order to further improve the proportion of the foaming components in the master batch, reduce the use of other additives and improve the cost performance of the foaming master batch, the patent provides the foaming master batch taking polyisobutylene as a carrier.
