They are complex mixtures of organic compounds, including various gum resin s, fats, or waxes and, in some instances, poisonous compounds, suspended in a watery medium with dissolved salts, sugars, tannins, alkaloids, enzymes, and other substances from which the latex (or natural rubber, the only available rubber until 1926) can be concentrated, coagulated, and vulcanized.

它们是复杂的有机化合物的混合物,含有各种树胶、脂肪或蜡,在某些情况下还含有有毒的化合物,悬浮于溶解有盐、糖、丹宁酸、生物碱、和其它物质的水性介质中,从中可浓缩、凝结和经硬化处理出乳胶(或天然橡胶,是1926年以前唯一可获得的橡胶来源)。

Soft or flexible rubber, except silicone rubber and natural latex

软的或易弯曲的橡胶,除了硅橡胶和天然乳胶

However, the first one enzyme 1-deoxy-D-xylulose 5-phosphate synthase gene and the second one enzyme 1-deoxy-D-xylulose 5-phosphate reductoisomerase gene in MEP pathway had been reported and expressed in the latex of rubber tree, indicating that MEP pathway may be involved in rubber biosynthesis.4 - hydroxy -3 - methyl -2 -- butenyl -4 - phosphate reductaseis the last enzyme that catalytic 4 - hydroxy -3 - methyl -(2E)- butenyl -4 - phosphate to generate isopentenyl pyrophosphate.

然而已有报道MEP途径中第1个酶1-脱氧-D-木酮糖-5-磷酸合成酶(1-deoxy-D-xylulose 5-phosphate synthase,DXS)基因和第2个酶1-脱氧-D-木酮糖-5-磷酸还原酶(1-deoxy-D-xylulose 5-phosphate reductoisomerase ,DXR)基因在橡胶树胶乳中的表达,这表明MEP途径可能参与橡胶的生物合成。4-羟基-3-甲基-2--丁烯基-4-磷酸还原酶(4-hydroxy -3-methyl-2--butenyl-4-diphosphate reductase,HDR)是异戊烯基焦磷酸合成途径之一甲基赤藓糖磷酸(methylerythritol phosphate,MEP)途径中的最后一个酶,催化4-羟基-3-甲基-(2E)-丁烯基-4-磷酸生成异戊烯基焦磷酸。

Compared with the Epoxy resorcinol-formaldehyde resin pretreatment system and Maleic anhydride pretreatment system developed by Xusigui, the 40% carbolated styrene-butadiene latex system can keep the composite"s properties and reduce the cost of pretreatment and simplify the pretreatment technology; especially to the HST 2073 latex system, the composite"s mechanics properties are improved greatly. Secondly, the composite"s comprehensive properties and interface performance are improved by reinforced with short fiber grafted with rubber in the surface. Thirdly, to simplify the production technology of composite, we add TKM-M and RF-90 as adhesive agent to the composite blended in an internal mixer, so as to the composite can be used to industry widely, then the effect of the amount adhesive agent on the composite"s properties and interface adhesive performance was studied, from the experiments the optimum amount of adhesive agent was deduced.

其中采用特软羧基丁苯胶乳预处理短纤维的方案,降低了预处理成本,相对许泗贵的低分子环氧和马来酸酐体系来说,预处理工艺大大简化了,而材料的力学性能保持良好,尤其是 HST 2073A 胶乳预处理体系,力学性能有较大幅度的提高;第二,通过对尼龙短纤维表面进行接枝橡胶分子链预处理,改善了复合材料的界面粘合性能,复合材料的综合性能也得到了相应的提高;第三,为了简化复合材料的生产工艺,使复合材料的应用得到工业化推广,我们选用TKM—M和RF—90长效增粘剂,直接加入短纤维橡胶复合材料中,采用密炼工艺,探讨了增粘剂的用量对复合材料界面粘合以及性能的影响,得出了增粘剂在复合材料中的最佳用量。

Commercial rubber comes from the latex of the rubber plants Ficus elastica and Hevea brasiliensis.
