The invention relates to a production method of an anti-bacterial SBR (
styrene butadiene rubber) foaming material. The ingredients includes, by weight parts, 20 to 40 parts of
natural rubber, 60 to 80 parts of main SBR materials, 10 to 15 parts of process / operation auxiliaries, 20 to 30 parts of
vulcanization / foaming auxiliaries, 40 to 50 parts of
processing oil and 120 to 150 parts of reinforcing filler. The production method includes steps of firstly, masticating; secondly, mixing; thirdly, opening
smelting; fourthly, fine
smelting; fifthly, open
smelting secondarily; sixthly, extruding; seventhly, vulcanizing and eighthly, foaming. The production method is characterized in that 3 to 5 parts of nanometer silver
powder are added into the ingredients according to
mass ratio, the first step of the production method includes feeding the
natural rubber and the nanometer silver
powder into an open smelting
machine or a fine smelting
machine to realize
mastication, and the second step of the production method includes feeding a primary product of the first step, the main SBR and the process / operation auxiliaries into the fine smelting
machine to mix. The production method of the anti-bacterial SBR foaming material has the advantages that anti-bacterial nanometer silver
powder can prevent physiological breeding of
bacteria while original characteristics of the foaming material are kept.
