用途:HVA-2在橡胶加工过程中既可作硫化剂,也可作过氧化物体系的助硫化剂,还可以作为防焦剂和增粘剂。在天然胶中,与硫磺配合,能防止硫化返原、改善 耐热性、降低生热、耐老化、提高橡胶与帘子线粘合力和硫化胶模量。用于载量轮胎肩胶、缓冲层等橡胶中,可解决斜交载重轮胎肩空。HVA-2 还可以作为辅助硫 化剂,能改善关联性能,提高耐热性,适用于高温硫化体系,降低压缩变形十分明显,还能减少过氧化物的用量,防止胶料在加工过程中的焦烧,提高胶料和帘 子线及金属的粘合强度。HVA-2属于无硫硫化剂,用于电缆橡胶,它可代替噻唑类、秋兰姆等所有含硫硫化剂,解决了铜导线和铜电器因接触含硫硫化剂生成硫
化铜污染发黑的难题。作为防焦剂为0.5~1.0份,作为硫化剂为2~3份,改善压缩变形为1.5份,提高粘合强度为0.5~5.0份。
Uses:HVA-2can be used as both a vulcanizing agent andaco vulcanizing agent for peroxide systemsin rubberprocessing,as well as an anti coking
agent and tackifierIn natural rubber,when combined with sulfur,it can prevent vulcanization from returning to its original state,improve heat
resistance,reduce heat generation,resist aging,increase the adhesive strength between rubber and cord,and increase the modulus of vulcanized rubber.Used in the shoulder rubber,buffer layer and otherrubbers of load bearing tires,it can solve the problem of shoulderspace in diagonal load
tires.HVA-2 can also be used as an auxilary vulcanizing agent to improve the correlation performance and heat resistance.It is suitable for
high-temperature vulcanization systems and significantly reduces compression deformation.It can also reduce the amount of peroxide used, prevent scorching of the rubber material during processing,and improve the bonding strength between the rubbermaterial,cord and metal.HVA-2 is a sulfur-free vulcanizing agent used in cable rubber.It can replaceallsulfur-containing vulcanizing agents such as thiazoles and thiuram,solving
the problem of copper wires and copper appliances generating sulfurized copper pollution and black hair due to contact with sulfur-containing
vulcanizing agents.As an anticoking agent,0.5-1.0 parts are used,2-3 parts are used as a vulcanizing agent,1.5 parts are used to improve
compression deformation,and 0.5-5.0 parts are used to increase adhesive strength.
