Method for regenerating reclaimed rubber and method for producing rubber rain boots using the reclaimed rubber

Abstract

The invention discloses a reclaiming method of reclaimed rubber and a manufacturing method of rubber rain shoes by using reclaimed rubber. The reclaiming of the reclaimed rubber comprises the following steps of: (a) designing a reclaiming process by adopting a taguchi method; (b) sorting and primarily processing raw materials; (c) cutting rubber; (d) crushing waste and old rubber at a low temperature; (e) treating after crushing; (f) desulfurizing by a microwave method; and (g) processing and treating the reclaimed rubber. Simultaneously, the reclaimed rubber prepared by the reclaimed method is used to produce the rubber rain shoes by the following steps of: (a) designing a production process by adopting the taguchi method; (b) weighing and clearing the raw materials; (c) mixing the raw materials; (d) sulfurizing the rubber; (e) pressing and forming soles; (f) pressing and forming uppers; and (g) bonding and forming. The reclaiming method disclosed by the invention has the advantages that the reclaimed rubber is adopted for replacing the traditional natural rubber and synthetic rubber, and therefore the manufacturing cost of a product is reduced and the considerable economic benefit is brought; the non-reclaimed resources can be reclaimed, so that the environmental pollution is avoided, the energy-saving and environmental-friendly effects are achieved, and the production of the rain shoes steps into economic circle with good circulation.

Description

technical field [0001] The invention relates to a method for regenerating reclaimed rubber and a method for making the reclaimed rubber for rubber rain boots. Background technique [0002] Regenerated rubber is processed from the vulcanized scraps in the production of rubber products. It has a certain degree of plasticity and can be reused. According to the different waste rubber used, reclaimed rubber is divided into outer tires, inner tubes, rubber shoes and so on. The essence of the waste rubber desulfurization and regeneration process is to destroy and degrade the waste vulcanized rubber network under the combined effects of heat, oxygen, mechanical action and the chemical and physical action of the regenerant, restore plasticity and viscosity, and be able to re-vulcanize. Reclaimed rubber can partially replace raw rubber for rubber products, saving raw rubber and carbon black is also beneficial to improve processing performance and certain properties of rubber products...

AI Technical Summary

Problems solved by technology

Traditional rubber rain boots use natural rubber and synthetic rubber. Natural rubber and synthetic rubber are non-renewable resources and are expensive. The market price is 25,000 yuan per ton, which is high cost and waste of resources.
