Odorless regenerated rubber and automobile foot pad prepared from same

Abstract

The invention discloses odorless regenerated rubber which comprises the following components in parts by weight: 1-10 parts of natural rubber, 0.5-5 part of butadiene-styrene rubber, 20-80 parts of regenerated rubber, 15-30 parts of calcium powder, 5-15 parts of rubber powder, 0.03-1 part of rubber accelerator, 0.1-2 part of zinc oxide, 0.1-2 part of stearic acid, 0.1-2 part of sulfur and 1-15 parts of aromatic hydrocarbon oil. The preparation process of the odorless regenerated rubber comprises the following steps: a) burdening: adjusting the roll spacing of a mixing mill to 8 m by adopting the open mixing mill, adding natural rubber, butadiene-styrene rubber, regenerated rubber, calcium powder, rubber powder, zinc oxide, stearic acid and sulfur, mixing the components for a period of time; then adding natural rubber, butadiene-styrene rubber, reclaimed rubber, calcium powder, rubber powder, zinc oxide, stearic acid and sulfur, mixing the components for a period of time, adding aromatic hydrocarbon oil, continuously mixing the components, and finally mixing the mixture with a rubber accelerator for 1 minute; secondly, adjusting the roller spacing of the mixing mill to 1.5 mm, and thinning the rubber for 5 times; and finally, adjusting the roller spacing of the mixing mill to 8 m, uniformly mashing the mixture, outputting the rubber sheet, and cooling the rubber sheet for 5h; B,molding: namely shaping the rubber according to the shape required by the product, so as to obtain the molded product, namely the automobile foot mat; C, vulcanization: vulcanizing the sheet materialby using a press vulcanizer.

Description

technical field [0001] The invention belongs to the technical field of rubber products, and in particular relates to an odorless regenerated rubber and a car floor mat prepared therefrom. Background technique [0002] Rubber products refer to various items produced with natural rubber and synthetic rubber as raw materials, which provide people with daily and medical light industrial rubber products that are indispensable in daily life, and are widely used in mining, transportation, construction, machinery, Electronics and other industries, such as seat cushions and floor mats in automotive interiors, are mostly made of rubber materials. [0003] Regenerated rubber is processed from vulcanized scraps in the production of rubber products. It has certain plasticity and can be reused. Regenerated rubber has always been an important raw material for the world rubber industry. It can replace natural rubber on the one hand. Rubber alleviates the serious shortage of natural rubber,...

Problems solved by technology

However, rubber products made of recycled rubber generally have the disadvantage of poor weather resistance. For example, Wang Sixian pointed out in "Research and Development of High Hydrocarbon Content and Aging-Resistant High-quality Reclaimed Rubber" in "Comprehensive Utilization of China's Tire Resources CTRA" No. 12, 2011. Low hydrocarbon content and poor aging resistance, most recycled rubber can only be used as filling materials

Due to poor aging resistance, the application of recycled rubber in the rubber industry is limited
