[求助] 求達人潤色一段英文摘要

題名：防毒面具罩體材料的物理機械性能

摘要：本文對兩種不同防毒面具罩體的膠料進行了物理機械性能表征，結(jié)果表明：在現(xiàn)有配方及硫化條件下，NR罩體材料的拉伸強度22.0MPa、撕裂強力41.3KN∙m-1，高于鹵化丁基膠罩體材料的13.2MPa和35.5KN∙m-1，差異的原因在于NR具有較高的自補強性能；NR罩體材料的回彈率為60%，CIIR罩體材料回彈率為16%，CIIR罩體材料回彈率偏低的原因主要是分子結(jié)構(gòu)中占優(yōu)的異丁烯鏈節(jié)上密集的側(cè)甲基造成的內(nèi)摩擦損耗較大。經(jīng)過100oC×24h熱氧老化后，兩種罩體材料硬度均有約2度的增加，NR罩體材料的拉伸強度、斷裂伸長率、撕裂強度呈上升趨勢，而CIIR罩體材料扯斷伸長率、撕裂強度降低。硫化改變了橡膠的原有結(jié)構(gòu)，使得老化對材料性能的影響更為復雜。

Title ：Physico-mechanical properties of Faceblank for Gas Mask

Abatract: This paper presents physico-mechanical properties of two faceblanks for gas masks. The results show that under the existing rubber formula and curing conditions, NR faceblank with a high self-inforceing possibility offer tensile strength of 22.0MPa and tearing strength of 41.3KN∙m-1, higher than the CIIR faceblank which are 13.2MPa and 35.5KN∙m-1, respectively. Resilience of the NR faceblank is 60%, much higher than the CIIR faceblank which is 60%. Poor resilience of CIIR faceblank is due to the great internal friction which is originated from the dense side methyl groups in the predominantly isobutylene units. After thermo-oxidative ageing at 100oC for 24 hours, both of the two rubbers increase approximately 2 drgree in shore hardness, and an increase of tensile strength, elogation and tearing strength of the NR faceblank was observed, the elogation and tearing strength of the CIIR faceblank had shown a decreasing trend by contrast. Curing changes the orginal structure of rubbers, and makes the impacts of ageing on the physico-mechanical properties more complicated.
