Embodiment 1
[0042] Embodiment 1 produces latex condom
[0043] One, the basic process formula is as follows (by weight):
[0044] Concentrated natural rubber latex (calculated as dry rubber) 100
[0045] Modified plant fiber powder 1~5
[0046] Dispersant (emulsifier OP: alkylphenol polyoxyethylene ether) 0.3
[0047] Dry enzyme 0.1
[0048] KOH0.15
[0049] Sulfur 1.2
[0050] Accelerator PX (zinc N-ethyl-N-phenyldithiocarbamate) 0.8
[0051] Accelerator ZDC (zinc diethyldithiocarbamate) 0.4
[0052] Antiaging agent 264 (2,6-di-tert-butyl-p-cresol) 1
[0053] ZnO 0.6
[0054] 2. Implementation steps:
[0055] First take plant pineapple leaf fiber, add 5-15% maleic anhydride chemical modifier (based on plant fiber mass), then add 6-25% grinding aid polypropylene (based on plant fiber mass), and then use the grinding disc type The milling method of the mechanochemical reactor treats the plant fiber for 0.5-1 hour to obtain the modified plant fiber micropowder.
