Abstract

The invention provides a novel gel reagent for primary processing of natural rubber, a preparation method and an application method thereof, and belongs to the technical field of chemical products, wherein the primary processing comprises: performing primary treatment on collected fresh latex to obtain a crude rubber, and the novel gel reagent comprises hydroxyformate. By adopting the novel gel reagent disclosed by the invention, all reagents necessary for the traditional technology do not need to be added, and the process flow is simple; particularly skim can be returned to the field immediately, so that all burdens of traditional wastewater treatment are avoided, and the comprehensive cost is low; and ecological environmental protection and circular economy are remarkable.

Description

technical field [0001] The hydroxyformic acid hydrochloric acid of the present invention is a new reagent for condensing natural rubber, which is used in the condensing rubber process during the primary processing of natural rubber, and belongs to the technical field of chemical products. Background technique [0002] In the initial processing of coagulation of fresh natural rubber latex, reagents such as ammonia, sulfuric acid, formic acid, acetic acid, phytic acid, benzoic acid and biological enzyme preparations must be added in the existing traditional process, although the proportions of reagents added are also different. , but the average production of each ton of standard rubber will inevitably produce more than 20 tons of acid-containing and ammonia-containing wastewater. The equipment and facilities treated with existing technologies require huge investment, high operating costs, and ineffective effects. At the same time, a large amount of stench is produced, which p...
