结合胶理论 结合胶也称为炭黑凝胶，是指炭黑混炼胶种不能被其它溶剂溶解的那部分橡胶。结合橡胶实 质上是填料表面上吸附的橡胶，也就是填料与橡胶间的界面层中的橡胶。通常采用结合橡胶 的多少来衡量炭黑和橡胶之间相互作用力的大小，结合胶多则增强性高，所以集合胶的量是 衡量炭黑增强能力的量度。研究人员在原有结合模型的基础上结合应力分析结果，提出了新 的模型理论结合胶双层模型理论。该理论模型认为，吸附在炭黑外围的结合胶由2层橡胶层 组成，但这2层的结构没有交联，并且模量也不相等，里层是聚合物的玻璃化硬层，此层的 聚合物处于玻璃态，这一层的聚合物分子运动是受到限制的；而外层为黏性硬层。玻璃化硬 层在所有的应变幅度下对于应力作用均为定值，它只是增加了炭黑粒子的有效直径；在小应 变时表现和點性硬层基体相似，对于模量的贡献也不是很大；在应力逐渐增大的情况下，由 于黏性硬层发生取向，对模量增大的贡献很大，而玻璃化硬层由于分子链活动受到限制没有 发生取向，X抖莫量增大没有发挥作用。不同粒子之间的黏性硬层在用量较髙时发生重叠， 从而形成超网络结构，这种超网络结构在大的应力下会发生取向变硬，影响着模量的变化， 由于分子链之间是束状排列，造成束与束的间隙形成一些微小的空洞，这些空洞能够使拉伸 状态下的聚合物体积发生膨胀，从而吸收部分能量，延缓了分子链的破坏速率。此外，这个 模型理论也很好地解释应力软化现象。 |

Theory of bond rubber Bond rubber, which is also known as carbon black gel, refers to the rubber that carbon black mix cannot be dissolved by other solvents. Bond rubber is virtually the rubber that adsorbs on the filler surface, namely, the rubber in the boundary layer between filler and rubber. The amount of bond rubber is used to measure interaction force between carbon black and rubber. The more the bond rubber is, the higher the enhancement is. Thus, the amount of bond rubber is the measurement of enhancement ability of bond rubber. Based on the original binding model, the researchers combined with the results of stress analysis and put forward a new model theory: the theory of double-layer model of bond rubber. According to the theoretical model, bond rubber that is adsorbing in the periphery of carbon black is composed of 2 layers of rubber layers. However, the structure of these 2 layers has no cross-linkage, and modulus is not equal. The interior layer is vitrified hard layer of polymer, in which polymer is in vitreous state and the polymer molecular motion is restricted. The outer layer is viscous hard layer. Under all strain amplitude, vitrified hard layer on the stress effects is constant value. It just increases the effective diameter, and its performances are similar with the viscous hard layer matrix in the small strain, and the contribution to modulus is not very great. In the case of gradual increase of the stress, the viscous hard layer occurs in orientation, which contributes greatly to the increase of modulus. Due to the limit of activities of molecular chains, the vitrified hard layer does not occur in orientation, which does not play a role in the modulus increase. The viscous hard layer among different particles overlaps at higher amount, so as to form the super network structure. The super network structure will occur in orientation hardening in the large stress and impact modulus changes. Some tiny voids will be formed in the gaps, because the molecular chains are arranged in fascicles. These voids make polymer volume expand under the tensile state, thereby absorbing part of the energy and delaying the destruction rate of molecular chains. In addition, the model theory also has a good explanation of the stress softening phenomenon. |

。少打了一个字母，应该是bound rubber。 Theory of bound rubber Bound rubber, which is also known as carbon black gel, refers to the rubber that carbon black mix cannot be dissolved by other solvents.
