Conveyor belts and transmission belts are widely used in daily life due to their high working efficiency.
输送带和传动带所复合的织物主要作用是连接弹性体，保持弹性体尺寸稳定性，还有着保护弹性体不受磨损、浸渍、腐蚀的功能，并且带体的强度、抗冲击性能、耐屈挠性能等也与织物的性能密切相关。The main function of the fabric compounded by the conveyor belt and the transmission belt is to connect the elastic body, maintain the dimensional stability of the elastic body, and protect the elastic body from abrasion, impregnation, and corrosion, and the strength, impact resistance, and flex resistance of the belt body Performance, etc. are also closely related to the performance of the fabric.
传统的输送带和传动带复合的织物有棉、聚酯、芳纶、锦纶等纤维织物，这些纤维织物虽然有着质轻价廉的优点，但是在应用到如长期光照、高温等相关极端工作环境下，也难以发挥出保护带体的作用。而近年来出现的浸胶帆布以其优良的环境适应性和优良耐温变性能渐渐被广泛应用；那么如何把进一步提升浸胶帆布的优点，就成了目前提升输送带和传动带的织物材料的一个新突破口。Traditional conveyor belts and drive belt composite fabrics include cotton, polyester, aramid, nylon and other fiber fabrics. Although these fiber fabrics have the advantages of light weight and low price, they are not suitable for use in extreme working environments such as long-term sunlight and high temperature. , It is also difficult to play the role of protecting the belt body. In recent years, the dipped canvas that has appeared in recent years has gradually been widely used due to its excellent environmental adaptability and excellent temperature resistance; then how to further improve the advantages of the dipped canvas has become the current fabric material for lifting conveyor belts and transmission belts. A new breakthrough.

2)表面包覆的浸胶层使得帆布与橡胶的粘接强度提高，这大大增加了帆布对带体的保护效果，还提高了耐磨性、耐腐蚀性、耐高温性及抗拉性，保证了带体在高强度、高温的场合下长久使用。2) The dipping layer coated on the surface improves the bonding strength between the canvas and the rubber, which greatly increases the protection effect of the canvas on the belt body, and also improves the wear resistance, corrosion resistance, high temperature resistance and tensile resistance. It ensures that the belt body can be used for a long time in high-strength and high-temperature occasions.
前述的耐高温浸胶帆布中，所述浸胶层由改性硅橡胶涂覆固化形成。硅橡胶优良的耐低温和耐高温性能，进一步保证了本发明的耐高温浸胶帆布能承受更高的温度，能在-45～180℃的温度范围内长期使用。In the aforementioned high-temperature-resistant dipped canvas, the dipped layer is formed by coating and curing modified silicone rubber. The excellent low temperature and high temperature resistance of silicone rubber further ensures that the high temperature resistant dipped canvas of the present invention can withstand higher temperatures and can be used for a long time in the temperature range of -45 to 180°C.
前述的耐高温浸胶帆布中，所述帆布是斜纹织物。此时，帆布的随形性和浸润性好，能保证与浸胶的结合牢固度。加上表面平滑和表面浸胶面积大，也减少了帆布出现褶皱、折痕的现象，保证了使用的长久性。In the aforementioned high temperature resistant dipped canvas, the canvas is a twill weave. At this time, the conformability and wettability of the canvas are good, which can ensure the firmness of the combination with the dipping glue. In addition, the surface is smooth and the surface has a large dipping area, which also reduces the phenomenon of wrinkles and creases on the canvas and ensures the durability of use.
前述的浸胶层，其采用了改性硅橡胶作为涂覆料，该涂覆料以液体硅橡胶为主料，还引入了硅溶胶、聚己内酰胺等共混复合，在制备基料的过程中，将端乙烯基聚二甲基硅氧烷与氨基硅烷改性的单体共混再聚合，实现了端乙烯基聚二甲基硅氧烷与氨基硅烷改性的聚合物有效复合，之后与含有少量水的硅溶胶共混分散，通过脱水干燥，不仅形成了稳定的硅溶胶，且通过羧基与胺的反应，改善了硅溶胶、聚己内酰胺在液体橡胶间的分散性能，提高了乳液的均匀性、力学稳定性强度，本发明的改性硅橡胶经过固化后的涂层稳定性高，力学强度高，还具有聚己内酰胺优良的韧性、回弹性和耐热稳定性，综合性能优越。The aforementioned dipping layer uses modified silicone rubber as the coating material. The coating material uses liquid silicone rubber as the main material, and also introduces blending and compounding of silica sol, polycaprolactam, etc., during the preparation of the base material. , the vinyl-terminated polydimethylsiloxane and the aminosilane-modified monomer were blended and repolymerized, and the vinyl-terminated polydimethylsiloxane and the aminosilane-modified polymer were effectively compounded, and then combined with Silica sol containing a small amount of water is blended and dispersed. After dehydration and drying, not only a stable silica sol is formed, but also the dispersion performance of silica sol and polycaprolactam in liquid rubber is improved through the reaction of carboxyl groups and amines, and the uniformity of the emulsion is improved. The modified silicone rubber of the present invention has high coating stability and high mechanical strength after curing, and also has excellent toughness, resilience and heat resistance stability of polycaprolactam, and has excellent comprehensive performance.
