1. a semi-open type superheated vapour spray-drying process prepares the method for high filled composite rubber master batch, it is characterized in that:

  • the preparation mass percent concentration that adds water is the mineral filler suspension of 2% ~ 30%, 15min is ground after adding modifier treatment, mineral filler suspension after process is added rubber latex, mineral filler quality is 25 ~ 120% of rubber latex dry glue quality, the mixing suspension of mineral filler/rubber latex is obtained after stirring, in mixing suspension, particulate matter diameter is 5 ~ 20 μ

    m, semi-open type superheated vapour spray drying treatment, atomization droplets diameter is 30 ~ 100 μ

    m, spray drying device inlet temperature 150 ~ 350 DEG C, temperature out 100 ~ 120 DEG C, obtain the Powdered or rubber combined rubber master batch of microballon shape.
