Description
Technical field
The present invention relates to a kind of rubber ingredients, particularly relate to pre-dispersed masterbatch particles of a kind of granule type whipping agent and preparation method thereof.
Background technology
Rubber pange refers to that thereby processing rubber with specific whipping agent makes rubber have the processing means of characteristic performance.Quality problems during for fear of rubber pange must be to have appropriate active foaming agent.
4,4 '-OBSH, claims again OBSH; Be a kind of linen pressed powder, be mainly used as the whipping agent of rubber and plastics.The kind of domestic this class whipping agent is fewer at present, is mainly the AC whipping agent of yellow powder.
Pre-dispersed masterbatch particles be auxiliary agent high consumption (be especially difficult to disperse inorganics) with the rubber of low consumption and on a small quantity softening oil and dispersion agent etc. by specifically mixing, dispersion and granulation process be dispersed in auxiliary agent in advance and in rubber, form rubber ingredients master batch product.This pre-dispersed masterbatch particles is produced for rubber item, not only reduce dust pollution, improved metering accuracy and accessibility, the more important thing is the speed of sneaking into, rate of dispersion and the dispersing uniformity that have guaranteed auxiliary agent, also can effectively reduce on the other hand mixing energy consumption, effects of energy saving and emission reduction is remarkable.
Therefore, need to research and develop corresponding technology by 4,4 '-OBSH is prepared into the pre-dispersed masterbatch particles of whipping agent.
Summary of the invention
Technical problem to be solved by this invention is to provide pre-dispersed masterbatch particles of a kind of granule type whipping agent and preparation method thereof.In the preparation process of the pre-dispersed masterbatch particles of granule type whipping agent of the present invention, the median size of its raw material OBSH reaches 10-12 μ m, can not produce dust from flying after being processed as masterbatch particles, has improved production environment; Masterbatch particles OBSH, due to pre-dispersed with rubber carrier, because adding the special formulation in man-hour, has reduced the decomposition temperature of OBSH, has effectively guaranteed the activity of OBSH.Sticky group under masterbatch particles room temperature prepared by preparation method of the present invention, makes batching convenient, accurate; Under lesser temps, as 50 ℃ have compared with low mooney viscosity, improve the dust dispersion quality of OBSH in sizing material; Make foaming product aperture careful even, there is good consistency from different rubber, be applicable to all foaming or foam rubber products.
