SilanesIndex. décimale : 668.4 Plastiques, vinyles Résumé : Carbon black (CB)-filled rubber composites are widely used for tire tread and other rubber products due to their good abrasion resistance and reinforcement. Numerous studies have been focused on the filler-rubber interaction with the aim of obtaining optimum performances. In order to investigate the effect of modification on properties of diene rubber composites, a modified CB-filled isoprene rubber (IR) composite was prepared with a multi-functional silane coupling agent, 2-aminoethyl-2-(3-triethoxysilylpropyl)aminoethyl disulfide (ATD). This modification significantly enhanced the CB-IR interaction and improved CB dispersion. For the modified CB/IR vulcanizates, the tensile strength, stress at 300% elongation, temperature rise, and dynamic loss coefficient were significantly improved at low ATD dosage (1.5 phr). Such modification provides an effective route to prepare CB-reinforced diene rubber composites with low hysteresis and improved mechanical properties.

Poudre de cuirIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : In the processes of leather dressing as well as in nontanned hide processing, there are considerable losses of collagen. Half of the hide collagen is rejected as waste products from the technological process.
The methods of leather waste utilization have been reviewed by Przepiórkowska et al. The literature suggests that leather wastes often are not chemically treated, while their properties such as fibrous character, heat stability, sorption capabilities and increased friction coefficient are utilized. However, the methods of detanning, chemical or enzymatic hydrolysis of chrome tanned wastes yield various forms of degraded collagen. According to many researchers, the detanning of chrome tanned wastes always fail to recover collagen protein in its original form. According to Heidemann, most of the long existing methods for the utilization of chrome tanned wastes cannot be practically implemented. In this connection it is necessary to develop such utilization methods that could provide products whose price would make up for the costs of raw materials and processing. This problem has been studied at the Institute of Polymers. The present study is aimed at the management of difficult wastes such as shavings of chrome tanned leathers from the tanning industry.
The waste collagen was utilized to produce elastomer composites. The incorporation of protein into a rubber compound containing synthetic isoprene rubber should provide a product with properties similar to those of a natural rubber mix, as it is well known that natural rubber contains some amount of protein in its composition.Note de contenu : - Thermal analysis of leather powders
