输送带用普通胶料的特点。一般输送带各种部件所用的胶料包括覆盖胶、缓冲胶、布层擦胶、布层贴胶四种。第一种：覆盖胶输送带使用时受物料的冲击、磨损和微生物侵蚀，以及各种老化作用。因此，要求覆盖胶具有较好的拉伸强度（≥18Mpa）和耐磨性（磨耗量0.8cm3/1.61Km），耐老化、耐生物侵蚀。此外还要求具有良好的粘性等工艺性能，配方设计要点如下：生胶以天然橡胶为主或并用适量的丁苯橡胶，含胶率控制在50%~55%。硫化体系采用硫磺、促进剂传统配合体系。在天然橡胶配方中，硫磺用量为2.5质量份左右；在丁苯橡胶配方中，硫磺用量为1.5~2.0质量份。促进剂一般采用M、DM并用，促进剂CZ、NOBS等后效性促进剂适合于含丁苯橡胶的胶料中。补强剂可选用高耐磨炭黑、中超耐磨炭黑等，用量为40~50质量份。软化剂常选用的品种有机油、重油、松焦油、古马隆树脂和石油树脂。第二种：缓冲胶输送带缓冲胶在覆盖胶和带芯层之间，能增加两者的粘合力，并可吸收和分散输送物料的冲击力，起缓冲作用。要求胶料具有良好的粘着性（胶与布的附着力≥3.15N/mm），弹性大、生热小、散热好、工艺性能好。生胶一般采用天然橡胶和顺丁橡胶并用，含胶率为50%~55%。硫化体系宜使用低硫配合，以提高胶层和布层之间的粘着力。促进剂采用M、DM、TMTD并用体系。炭黑常用高耐磨和半补强炭黑并用，用量不宜过多，通常在10质量份左右。软化剂选用增粘性较好的品种，如松焦油、固体古马隆等。 Characteristics of ordinary adhesive used in conveyor belts. General conveyor belts used in various parts of the rubber material, including cover rubber, buffer rubber, cloth layer, rubber, cloth layer, glue four. The first type: covering rubber belt, the use of materials by the impact, wear and microbial erosion, as well as a variety of aging. Therefore, covering the adhesive has good tensile strength (more than 18Mpa) and wear resistance (wear 0.8cm3/1.61Km), aging resistance, resistance to biological attack. In addition to good technological properties such as viscosity, formulation design key points are as follows: rubber to natural rubber or with the amount of styrene butadiene rubber, rubber content control in 50%~55%. Vulcanization system adopts sulfur and accelerant traditional matching system. In natural rubber formulations, the amount of sulfur was about 2.5 phr, and in the SBR formula, the amount of sulfur was 1.5~2.0. Promoters are generally used M, DM, and use, promoters, CZ, NOBS and other after effects of the accelerator, suitable for styrene butadiene rubber containing rubber. The reinforcing agent can be made of high abrasion resistant black carbon, super abrasion resistant carbon black and so on. The dosage is 40~50. Softeners often use a variety of oil, heavy oil, pine tar, ancient Malone resin and petroleum resin. Second: buffer rubber, conveyor belt, buffer rubber between the cover rubber and the core layer, can increase the adhesion between the two, and can absorb and disperse the impact of conveying materials, as a buffer effect. Require glue (glue has good adhesion and adhesion of the cloth over 3.15N/mm), elastic, heat, good heat dissipation, good processing performance. Rubber general use of natural rubber and butadiene rubber and rubber, with rate of 50%~55%. Vulcanization system should use low sulfur compound to increase adhesive force between adhesive layer and cloth layer. M, DM and TMTD were used as promoter. Carbon black is commonly used with high abrasion resistance and semi reinforcing black carbon. It should not be used too much, usually at about 10 mass. The softening agent viscosity better varieties, such as pine tar, solid ancient Malone etc..
