In this paper,the heat stability of ABS/PVC blends is studied under the dynamic-shear heating condition with Brabender rheometer and under static heating condition with differential scanning calorimetry(DSC),respectively. The experiment shows that(1)When the ratio of barium stearate/cadmiun stearate is 3:1,the stable efficiency of mixture stabilizer and the colourity of products are all fairly good.(2)The lubricant efficiency by using both mentioned-above stabilizer is much better than that by using wax and stabilizer of plumbum.(3)There is a minimum of dynamic-shear processing time with the variation of ABS/PVC blends composition.Meanwhile,it is also found that decompositson tempreture of PVC resin blends increases about 20℃ as soon as adding ABS into PVC,while the decomposition tempreture is almost constant with incresing the amount of ABS in blends.

本文主要介绍了采用Brahender塑化流变仪及DSC-Ⅰ热分析仪对ABS—PVC合金在动态剪切受热过程和静态受热过程中的热稳定性研究。结果表明,在Ba、Cd等金属皂盐与铅盐混合热定剂体系中,Ba、Cd皂盐的配比为3:1左右其热稳定效果和制品颜色为佳。石腊与Ba、Cd等金属皂盐稳定体系配合使用其润滑作用远较其与铅盐系稳定剂的配合使用好。ABS与PVC树脂的不同配比使合金的动态剪切可加工时间出现最低值,此结果与Condon等人的研究结果基本一致。同时在研究中还发现一个奇特的现象即只要在PVC树脂中加入少量的ABS树脂会使PVC树脂发生脱HCI降解反应温度上升约20℃左右,而ABS继续增加则PVC树脂脱HCI的降解反应温度基本不变。就此现象本文还作出了相应的解释。

Following the collision of the Sino-Korean plate and the Yangtze plate in the Early Devonian large-scale northward intracontinental subduction of the Yangtze plate relative to the Sino-Korean plate took place in Indosinian time. Through a study of the structural deformation of the basement (Pt_3) and cover (Z-T) on the southern margin of the Dabie-Qingling Mountains and in the lower Yangtze region. the author has demonstrated that the large deep-level ductile decollement-shear zone in the northern part of the Yangtze plate is precisely the product of this subduction. 1. From above downwards the structural deformation in the cover (Z-T) shows a change from upright folds→isoclinal folds→recumbent folds. The cleavages also transform from upright folds→inclined→horizontal ones and exhibit a style of listric structure. Recumbent folds of varying sizes are developed within the Sinian strata, accompanied by subhorizontal flow cleavages and strong stretching of gravels in gravel-bearing phyllite (Zhougang Formation Z_1~1) and moraine conglomerate (Sujiawan Formation Z_1~2), forming the NNE- or N-S- trending stretching lineation. 2. Strong subhorizontal flow cleavages and lineations, "A"-typpe recumbent folds, sheath folds and N-S- or NNE-trending stretching lineations are developed in the basement (Pt_3; the Yuelinghe, Liangyun, Hong'an, Zhangbaling and Haizhou Groups). The nonsymmetry of the crystal tail of feldspar and pressure shadow of pyrite along the xz plane, the s-c structure of mica and structural recrystallized quartz, the rotation of the inclusions of basic volcanic rocks and the gently inclined myllonite zone. all this indicates the existence of a high- strain shear zone. 3. From above downwards the metamorphism is progressive. and there appear high-pressure metamorphic minerals such as glaucophane, crossite, chloritoid, 3T-phengite and jadeite in the decollement layer of the basement. 4. The nonsymmetrical fabric analysis of quartz within the decollement layer (basement) implies the existence of south-directed shear, while the hom- ogenous fabrics in the gneiss of the Wudang Group below the Liangyun Group suggest that the deep-buried metamorphic rocks far from the decollement-shear zone has not been involved in the Indosinian decollement. 5. The finite strain analysis of Sinian deformed gravels (by use of Dunnet method) gave a Flinn index (K=0. 945. 1. 124) of nearly one. So a simple shear mechanism is considered. 6. Microstructure analysis shows that shear heating was produced in the late stage of the shear action and indicates the formation of structural recry- stallized quartz, high-temperature quartz fabric (1010), partial melting in strata and Indosinian granite. 7. The age of glaucophane and albite in the decollement layer is 210-230 Ma, representing the age of a large decollement. The author considers that the Indosinian fold belt of the Yangtze platform is an intracontinental mountain chain and did not result from simple compression. It is genetically related to the large-scale dutile decollement-shear zone between the cover and basement. This decollement structure is tho largest deep-level one ever discovered in China at present. The author also considers that the Tancheng-Lujiang fault was formed a bit later than the Indosinian decollement structure, as the result that the subsuction velocity of its eastern sector was greater than that of the western sector, It is a sinistral strike-slip, transform, ductile shear zone of "intracontinental subduction type".

The author has studied the distribution of gebthermal water, discharges of the fault gases, isotopic compositions of the hot springs in Western Yunnan earthquake prediction test site. The relationship between the geochemical characteristics of the main active faults with the types, intensity and depth of faulting was discussed. The author suggests that larger dynamo-metamorphic belt has developed at a depth of about 5.4-6.2 km in the northwest of Eryuan County, and it was the result of the intersection of NW-and NE-trending tectonic belts. The hot springs in the area closely relate to this metamorphic belt. They are typical shear-heating type springs, characterized by strive thermo-dynamic-metamorphism. The hot springs along the Red River fault are of deep cycle-heating type ones, containing many components from the mantle.
