1、Recently, blending of polymers has become an increasingly important area of research activity. Elastomeric blends are used for many reasons such as lowering the compound cost, for ease of fabrication and to improve the performance of the industrial rubber. Natural rubber (NR) and styrenebutadiene ru

2、bber (SBR) have been blended for a long time for these reasons. In this study, 12 different rubber compounds were prepared by using SMR-20 type of natural rubber and SBR-1502 type of styrenebutadiene rubber in different proportions, keeping fixed the total rubber quantity specified in the standard t

3、esting recipe. The mechanical and physical properties such as tensile strength, hardness, wear, carbon black, ozone resistance, density and rheological properties of the present industrial rubber were studied. Physical and mechanical test results were reported. The tensile, hardness and wear propert

4、ies of the NR/SBR blends with the increment of NR percentages were greatly enhanced. The study also indicated that filler materials affect on the physical and mechanical properties of the blends. Blending of two or more types of polymer is a useful technique for the preparation and developing materi

5、als with properties superior to those of individual constituents. It is important especially from an industrial point of view to control the state of mixing of polymer blends. An adequate polymer-blend process requires information and understanding of the blend behavior under production conditions.

6、The knowledge of the relationship among melt viscosity, elasticity, and pressure and process temperature is important for the design appropriate process equipment and for assessment of the optimum process conditions to produce materials that have required properties. Natural rubber has been studied

7、and reported on extensively because of its superior performance in tire applications. It is well installed that elastomers do not display all of the characteristics that are required. Elastomeric blends are used for many purposes such as lowering the compound cost. The complex shaped product may be

8、more easily fabricated during production. Natural rubber (NR) and styrenebutadiene rubber (SBR) have been blended for along time for these reasons. A lot of studies have demonstrated that the mechanical properties of such blends can be significantly improved by adding a suitable compatibiliser. NR b

9、lending has been widely studied and reported as good compatible blends that provide desirable mechanical properties. Another paper about the development of novel elastomeric blends containing NR and ultra-low-density polyethylene (ULDPE) reported by Tanrattanakul and Udomkichdecha. Conventional vulc

10、anization was performed and the physical and mechanical properties of the blend were determined. The results were compared with those obtained from NR blending with SBR. Blending SBR with NR can improve the tensile strength because NR crystallizes on stretching. Kim investigated the mechanical prope

11、rties of NR blended with SBR. Those study indicated that the mechanical properties of this blend were required reinforcement. Thus, filled polymer systems are very popular for the industry for both cost and performance objectives. It is also well established that carbon black (CB) is one of the most

12、 important classical reinforcing fillers, especially for the rubber technology for cheaper Vulcan sates. New materials are also considered as fillers, whether for more economical reasons or rather to impart some desirable characteristics of CB as one of the major inputs in tire industry, has some ex

13、traordinary features. Surface area of CB is one of the most critical parameters considered for degree of reinforcement, which supply necessary sites to polymer chains for wetting. As some of the polymer chains may also enter into the holes of the particles depending on the rheological (viscosity) pr

14、operties of the polymers, the so-called physical entrapment and physical crosslink may also play an important role during reinforcement of elastomeric matrices. One of the most important parameters for the performance of a composite material is the degree of adhesion at the matrix filler interface.最

15、近，聚合物混合已成為研究活動(dòng)中一個(gè)日益重要的領(lǐng)域。彈性體共混物的應(yīng)用有很多原因，如降低復(fù)合成本，易于制造，并可提高工業(yè)橡膠的性能。由于這些原因，天然橡膠和丁苯橡膠的混合已有一段時(shí)間。在這次研究中，通過(guò)使用不同比例的SMR-20型天然橡膠和SBR-1502 型丁苯橡膠，制得了12種不同的橡膠化合物，并在指定的標(biāo)準(zhǔn)測(cè)試配方中保持固定的橡膠數(shù)量。同時(shí)還對(duì)力學(xué)性能和物理性能如拉伸強(qiáng)度、硬度、耐磨性、炭黑、耐臭氧性、密度和目前工業(yè)橡膠的流變性能進(jìn)行了研究。還對(duì)物理和力學(xué)性能實(shí)驗(yàn)結(jié)果進(jìn)行了報(bào)道。隨著天然橡膠比例的增加，天然橡膠/丁苯橡膠拉伸強(qiáng)度、硬度和耐磨性大大提高了。研究還表明，填充材料影響著共混物的物
