橡膠在製造過程因硫化反應前的加工與硫化反應，對原料均會產生一些變化，進而影響產品性質，同時，對工作環境亦有所影響。氯平橡膠含有相當比例的氯離子，加工過程會脫離本體而成為氯化氫氣體，對操作人員與設備均有所危害。為了解加工條件對硫化過程脫氯化氫的影響，本文即針對氯平橡膠硫化前的加工條件與硫化溫度等變因，利用流變硫化儀，探討上述條件在硫化過程與對物性的影響，再以硫氯儀檢測產品最後殘存的含氯量。結果指出，混練時間長短與混練期間有無加冷卻水會影響硫化速率及交鏈度，此等效應可硫化曲線得到說明；高硫化溫度會使硫化反應提早發生及提早結束;由所得樣品之伸張強度與伸長率結果，配合硫化過程的扭力變化，也說明高硫化溫度所殘留的餘溫會加速老化的作用。產品中殘存氯測試結果指出，混練時間較長與硫化溫度高，殘存氯氯量少，此種影響在混練期間有加冷卻水比無加冷卻水者來得明顯。 For rubber products, the changes in the properties of the raw materials during the processing and the vulcaoization would aNect the quality of the product and polluted the working enviroment. For example, the content of chlorine which contains in neoprene rubber will escape from the polymer matrix and evolve into the hydrochloride during the processing of vulcanization, and may endanger the operators and facilities. To understand the effects of the various processilg conditions on the dehydrochlorization, this study first investigated the effects of wlcanization and properties of products under three conditions by Rheometer, and then estimated the residual of the chlorine in the product after the procming by Total Halogen Analyzer. The results showed that the mixing time and cooling during the mixing would affect the vulcanization rate and the degree of the crosslink. This phenomenon could be explained by the curve of vulcanization. The higher the temperature of the vulcenization, the earlier the vulcanization begins and ends. The tensile strength and the elongation of the products with the change of the torque of the rubber matrix in the Rheometer could explain that the residue temperature after high temperature vulcanization accelerate the aging of the products. The evaluation of the residual chlorine in the product indicated that the longer the mixing time and the higher the temperature of the vulcanization, the less the residued chlorine left in the product.
