Embodiment Construction

[0036] One of the main rubbers in the rubber mixing process, natural rubber (because it is a polymer material containing a large amount of protein), is added to the separate mastication stage (step 1 in the background technology) to add nano-silver antibacterial powder to evenly disperse the nano-silver to the natural rubber. Among them, the product is made through banburying and refining, extrusion and vulcanization foaming process, endowing it with permanent antibacterial function. In a broad sense, the proportion of natural rubber and SBR can be any ratio.

[0037] The particle size of the nano-scale silver powder is 200-300 mesh.

[0038] Join process:

[0039] ①Natural rubber and nano-silver powder are put into the 10,000-horsepower closed mixing and kneading machine according to the formula ratio, and the temperature reaches 130°C after 5 pressurizations (100 seconds / time). (Pay special attention to the matching of the volume of the machine with the actual input amount...

Abstract

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.

Description

Technical field: [0001] The invention relates to a rubber foam material, in particular to a production method of an antibacterial SBR rubber foam material. Background technique: [0002] Diving suits commonly used in water sports activities use SBR (synthetic rubber) foam material as the middle layer material (the outer layer is mostly Meijia cloth, resistant Meijia cloth, etc.), due to water activities, microorganisms and bacteria will erode through the surface textile layer , the SBR rubber foam material in the middle layer will breed bad bacteria, shorten the service life, wear close to the body, and affect health. [0003] Recipe description (parts by mass): [0004] The formula of SBR production materials is as follows in parts by mass: [0005] Natural rubber: 20-40 parts [0006] SBR main rubber (such as: styrene-butadiene rubber): 60-80 parts [0007] Processing / operation aids (such as: dispersant, anti-aging agent, etc.): 10-15 parts [0008] Vulcanization / foam...
