  • Publication number: 20220380490
    Abstract: A method for concentrating rubber emulsion and a product prepared by the method are provided, the method includes: a concentrated latex is obtained by separating a superabsorbent resin added in advance into a rubber emulsion with a solid content of 0.01-70% after stirring and concentrating the resin-added rubber emulsion. The method requires simple equipment and consumes less energy, and the prepared polymer emulsion has a solid content up to 76%; the superabsorbent resin adopted herein is reusable after drying, which therefore effectively reduces the production cost; natural latex concentrated by the method has rather high yields of dry rubber and little wastewater production; products prepared from the concentrated natural latex have excellent mechanical property, aging resistance and adhesive property; and concentrating natural latex according to this method does not require advance agglomeration, which reduces the production procedures and improves the production efficiency significantly.
