Abstract
A method of manufacturing a dandelion latex shoe component. Dandelion rubber, CIS polybutadiene rubber (BR), and butadiene styrene rubber (SBR) are mixed together to form a first mixture. The dandelion rubber, CIS polybutadiene rubber (BR), and butadiene styrene rubber (SBR) are mixed at a temperature not less than 60° Celsius and not greater than 80° to form the first mixture. Silicon dioxide is then mixed with the first mixture to form a second mixture. The silicon dioxide is mixed with the first mixture at a temperature not less than 80° Celsius and not greater than 100° Celsius to form the second mixture. The dandelion latex shoe component is then formed from at least the second mixture via a molding process.
Claims18
A method of manufacturing a dandelion latex component, the method comprising:
- mixing together dandelion rubber, CIS polybutadiene rubber (BR), and butadiene styrene rubber (SBR) at a temperature not less than 60° Celsius and not greater than 80° Celsius to form a first mixture;
- mixing silicon dioxide with the first mixture at a temperature not less than 80° Celsius and not greater than 100° Celsius to form a second mixture;
- and
- forming a component from at least the second mixture via a molding process.
A method of manufacturing a dandelion latex component, the method comprising:
- mixing dandelion rubber with BR to form a first intermediate mixture;
- mixing the first intermediate mixture with SBR to make a first mixture;
- mixing silicon dioxide with the first mixture to form a second mixture;
- mixing one or more of zinc oxide, DM, sulfur, and blowing agent with the second mixture to form a third mixture, the dandelion rubber comprising 10-74% by weight of the third mixture, the BR comprising 10-70% by weight of the third mixture, the SBR comprising 10-40% by weight of the third mixture, the silicon dioxide comprising at least 5-30% by weight of the third mixture;
- and
- forming a component from the third mixture via a molding process.
