Newsprint paper waste as a fiber reinforcement in rubber composites

Abstract

ABSTRACT:The investigation of the economical use of lignocellulose waste, which is one of the environmental problems facing third-world nations, is ongoing. In this study, we intended to increase the use of newsprint fibers in the rubber industry. For this reason, we treated newsprint fibers with sodium silicate and magnesium chloride, and we examined the water retention values and thermal degradation analyses of the treated fiber waste. The activation energy of degradation was evaluated with the Coats-Redfern method of analysis. The effects of the addition of different amounts [0 -60 parts per hundred parts of rubber by weight (phr)] of untreated and treated newsprint fibers on both the electrical and mechanical properties of two different types of rubber (natural rubber and acrylonitrile rubber) were studied. This study led us to the conclusion that the addition of treated newsprint fiber waste at a concentration of 40 phr could lead to an end product characterized by good electrical and mechanical properties.

Preparation of rubber composites from ground tire rubber reinforced with waste‐tire fiber through mechanical milling

“…11 The properties of short-fiber-reinforced composites mainly depend on the type and concentration of the fiber, the orientation and distribution of the fiber after mixing, the aspect ratio of the fiber, and the degree of adhesion between the fiber and the matrix. 12,13 The interfacial bond is known to play an important role in composites because this interface is critical to the composite performance. Waste fibers represent another type of environmental problem and are normally disposed of in controlled dumps or subjected to expensive recycling processes.…”

Cellulose Nanocrystals from Lignocellulosic Raw Materials, for Oxygen Barrier Coatings on Food Packaging Films

“…Cellulose is the main constituent of higher plants tissues and is also found in marine animals (tunicates), in algae, fungi, bacteria and invertebrates in small quantities . As well as in natural resources, however, it is also hugely abundant in a number of waste biomasses, industrial by‐products, recycling streams and rubbish . From a chemical point of view, it is a linear polysaccharide formed by a chain of β‐1,4 linked D‐glucose where each subsequent glucose molecule is inverted 180°; therefore, the fundamental unit is frequently taken to be cellobiose , a dimer of glucose.…”

Effect of Chitosan and its Derivatives on the Mechanical and Electrical Properties of Paper Sheets

“…From infrared spectra Fig. (1), it is interesting to notice that chitosan and its derivatives have band (shoulder) appeared at 3063 cm -1 due to NH 2 stretching vibration [21]. On the other hand the relative absorbance of the band at 3400cm -1 which is characteristic to OH group (ratio of the absorbance at the subscript wave number 3400cm -1 to the absorbance of wave number at 1325 cm -1 which corresponds to the CH rocking of the ring) [22] is higher than that of cyanoethyl carboxymethyl chitosan (Table 1).…”
