日本語

本研究では、天然ゴムラテックスでコーティングしたアラミドパルプ（AP）をカーボンブラックの代替としてスチレンブタジエンゴムに添加し、低発熱性複合材料を開発した。AP含有量2.38 phrで最高の代替効率を示し、発熱温度を47.6℃から37.9℃に低減。新たな指標「Replacement-Temperature efficiency」を提案し、省エネタイヤ材料設計の定量化基盤を提供する。

English

This study uses natural rubber latex-coated aramid pulp (AP) to replace carbon black in styrene-butadiene rubber, reducing heat build-up. The optimal AP content (2.38 phr) replaces 6.55 phr of carbon black, lowering temperature from 47.6°C to 37.9°C. A new metric, Replacement-Temperature efficiency, is proposed for quantifiable design of energy-efficient tire materials.

📄 Abstract（原文）

Rubber heat build-up represents a significant challenge in the development of green and environmentally friendly tires. This study employed natural rubber latex (NRL) to coat aramid pulp (AP), constructing an AP-styrene-butadiene rubber (SBR) flexible interface layer. The effects of different AP contents replacing carbon black (CB) on the mechanical properties and heat build-up of rubber were systematically investigated, and the pivotal role of the modified AP content in reducing the heat build-up of SBR composites was explored. Additionally, based on replacement efficiency and heat build-up effect, the parameter of Replacement-Temperature efficiency (RT ef ) was proposed. The optimal AP content was determined to be 2.38 phr with the highest RT ef value, which replaced 6.55 phr of CB, reducing the heat build-up temperature from 47.6 ℃ to a minimum of 37.9 ℃. This concept provides a quantifiable basis for designing and optimizing preparation of rubber composites, thereby offering a novel strategy for developing energy efficient and durable tires materials.
