天然橡胶

In recent years, as automobiles, machinery, aviation, aerospace and chemical industry have developed in the direction towards high performance, low power consumption and long life, general rubber such as nature rubber, chloroprene rubber, and acrylonitrile butadiene rubber etc can not satisfy thermal stability and oil resistance in new rubber products.

近年来，随着汽车、机械、航空、航天、化工等领域使用的橡胶制品向高性能、低能耗和长寿命方向发展，天然橡胶、氯丁橡胶、丁腈橡胶等通用橡胶已无法满足新型橡胶配件耐高温和耐油等方面的要求。

Company to operate general-purpose rubber-based, mainly related to natural rubber, SBR, nitrile rubber, butadiene rubber, neoprene, glue and another involved in stearic acid, paraffin, carbon black, white carbon black, Coumarone, zinc oxide, magnesia, and all kinds of rubber accelerator; In recent years, the company is operating in special rubber growing trade company-wide diversity in the trade, chemical industry cooperation generalization, a total of market efficiency win development.

公司以经营通用型橡胶为主，主要涉及天然橡胶、丁苯胶、丁腈胶、顺丁胶、氯丁胶、复合胶，另外涉及硬脂酸、石蜡、炭黑、白炭黑、古马隆、氧化锌、氧化镁、及各种橡胶促进剂；近年来，公司在特种橡胶经营方面不断增强贸易往来，全公司在向贸易多元化，化工合作普遍化，市场效益共赢化发展。

The present invention relates to a rubber composition including 100 parts by mass of a rubber component including a natural rubber and/or a diene rubber and 0.5 to 80 parts by mass of a biodegradable aliphatic polyester.

本发明涉及相对于含有天然橡胶及/或二烯烃系橡胶的100质量份橡胶成分，进而在0.5～80质量份的范围内含有生物降解性脂肪族聚酯的橡胶组合物。

Mainly use C5 petroleum resins, C5/C9 copolymerized resins and DCPD resins with low softening points, these kinds of resins have very good mutual solubilities with natural rubber particles, No affect to the sulphurization of rubber.

橡胶主要使用低软化点的C5石油树脂、C5/C9共聚树脂及DCPD树脂。此类树脂和天然橡胶胶粒有很好的互溶性，对橡胶硫化过程没有大的影响，橡胶中加入石油树脂能起到增粘、补强、软化的作用。

Fumed silica was surfacely modified with resorcinol and hexamethylenetetramine complex, and the product was then reacted with natural rubber to prepare NR/modified fumed silica (NR/M-silica) nano-composites via a mixing and curing process.

用间苯二酚与六亚甲基四胺络合物对气相法白炭黑进行表面改性，产物与天然橡胶混合，通过混炼和硫化制备了天然橡胶／改性气相法白炭黑(NR/M-silica)纳米复合材料。

C Natural rubber modified by grafting or mixing with plastics,depolymerized natural rubber, mixtures of unsaturated syn- thetic substances with saturated synthetic high polymers provided that all the above-mentioned products comply with the requirements concerning vulcanisation, elongation and recovery inabove.

三与塑料接枝共聚或混合而改性的天然橡胶、解聚天然橡胶以及不饱和合成物质与饱和合成高聚物的混合物，但这些产品必须符合以上款关于硫化、延伸及回复的要求。

The high-resolution appearance of the NMR spectra suggests that a small amount of crystals do exist in unstretched NR samples at room temperature.

发现未拉伸的天然橡胶样品室温下也存在少量结晶，该结果为天然橡胶在室温下存在结晶的观点提供直接的证据。

Effective network chain density measurement, dynamic mechanical spectrum measurement, wide angle X-ray diffraction and density measurement have been used to verify the compatibility of natural rubber/low density polyethylene blends (NR either unvulcanized or vul-canized) as predicted by the calculation and proposed model.

然后用动态力学方法、有效网链密度测定、密度测定和广角X-射线衍射方法对天然橡胶分别未交联和交联的天然橡胶/低密度聚乙烯共混体系的相容性进行了验证。

The effects of three coagulation methods on the properties of natural rubber,carbon black /natural rubber vulcanized were investigated.

研究了三种不同凝固方法对天然橡胶性能和炭黑/天然橡胶硫化胶力学性能的影响。

China takes the production, consumption and import of natural rubber as a whole.

中国是全球最大的天然橡胶消费国和进口国，也是第五大产胶国，集天然橡胶的生产、消费和进口于一体。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
