Description

陶瓷复合型橡胶输送带覆盖层及耐磨耐冲击橡胶输送带Ceramic composite rubber conveyor belt covering layer and wear-resistant and impact-resistant rubber conveyor belt 技术领域Technical field
本发明涉及橡胶材料及其制品，具体涉及陶瓷复合型橡胶输送带覆盖层及以其为覆盖层的耐磨耐冲击橡胶输送带。The present invention relates to rubber materials and products thereof, in particular to a ceramic composite rubber conveyor belt covering layer and a wear-resistant and impact-resistant rubber conveyor belt using the covering layer as the covering layer.
背景技术Background technique
悬臂机专用输送带耐磨性分为：起卷磨耗、腐蚀磨耗、疲劳磨耗，但在输送带行业一系列标准只对起卷磨耗做出明确要求，例如，超耐磨覆盖胶 DIN 起卷磨耗要求≤35mm，但输送带进行运输作业过程中，尖锐的物料与输送带之间会产生类似于刀片刻划的作用，导致输送带的磨损加速。因此，在较多的场合（例如钢铁厂悬臂机上），需要输送带具有耐切割的性能来提高输送带的使用寿命。陶瓷有着比橡胶更好的耐磨性、耐候性、抗切割性能、耐低温性能和抗冲击性能，但因其难以与橡胶实现高强度结合，导致复合了陶瓷的橡胶产品使用寿命短，实用性差，目前在橡胶制品中运用并不多见。The wear resistance of special conveyor belts for cantilever machines is divided into: rolling wear, corrosion wear, and fatigue wear. However, a series of standards in the conveyor belt industry only make clear requirements for rolling wear, for example, super wear-resistant covering glue DIN rolling wear The requirement is ≤35mm, but during the transportation operation of the conveyor belt, an effect similar to that of a knife blade will occur between the sharp materials and the conveyor belt, resulting in accelerated wear of the conveyor belt. Therefore, in many occasions (such as on cantilever machines in steel plants), the conveyor belt needs to be cut-resistant to extend the service life of the conveyor belt. Ceramics have better wear resistance, weather resistance, cutting resistance, low temperature resistance and impact resistance than rubber. However, because it is difficult to achieve high-strength bonding with rubber, rubber products compounded with ceramics have a short service life and poor practicality. , currently rarely used in rubber products.

Ceramic nails are embedded in an array on the upper surface of the upper covering base adhesive layer, and are covered by the upper covering sheet adhesive layer, which protects the ceramic nails and effectively prevents the occurrence of ceramic The nails fall off; at the same time, the setting of ceramic nails also improves the cutting resistance and impact resistance of the conveyor belt, which slows down the wear and extends the service life of the conveyor belt;
2）本发明的上覆盖基底胶层的混炼胶具有良好的流动性和可塑性能，并且配方中加入少量的过氧化物硫化促进剂1，4-双叔丁基过氧二异丙基苯，硫化后，陶瓷钉与橡胶的粘合强度较高；2) The compound rubber covering the base rubber layer of the present invention has good fluidity and plasticity, and a small amount of peroxide vulcanization accelerator 1,4-bis-tert-butylperoxydiisopropylbenzene is added to the formula , after vulcanization, the bonding strength between ceramic nails and rubber is higher;
3）陶瓷钉由钉帽和钉体组成，钉帽起到有效保护覆盖层橡胶的作用，钉体扎入橡胶中，起到提高结合强度的作用；3) Ceramic nails are composed of a nail cap and a nail body. The nail cap effectively protects the covering rubber, and the nail body penetrates into the rubber to improve the bonding strength;
4）本发明方案通过对陶瓷钉进行预处理，提高陶瓷与橡胶的黏合强度，具体表现为：预处理过程中，采用了将陶瓷钉浸渍在环氧化改性的苯乙烯丁二烯苯乙烯嵌段共聚物溶液中，天然橡胶的表面张力大约为32×10-5N/cm，而SBS的表面张力与天然橡胶近似，采用改性的SBS溶液浸渍改性陶瓷钉，可以促进与天然橡胶的相容性，同时，本发明采用环氧改性SBS溶液，而在橡胶的制备过程中加入了环氧基的硅烷作为相容剂，更加有效的促进了陶瓷钉与橡胶的相容性，降低了两相界面的表面张力，从而使陶瓷和橡胶可以更牢固的粘结在一起，有效提高陶瓷钉与橡胶的黏合强度；4) The scheme of the present invention improves the bonding strength between ceramic and rubber by pre-treating the ceramic nails. Specifically, the ceramic nails are impregnated in epoxidation-modified styrene butadiene styrene during the pre-treatment process. In the block copolymer solution, the surface tension of natural rubber is approximately 32×10-5N/cm, while the surface tension of SBS is similar to that of natural rubber. Impregnating modified ceramic nails with modified SBS solution can promote the interaction with natural rubber. Compatibility, at the same time, the present invention uses epoxy-modified SBS solution, and adds epoxy-based silane as a compatibilizer during the preparation process of rubber, which more effectively promotes the compatibility between ceramic nails and rubber and reduces The surface tension of the two-phase interface is increased, so that ceramic and rubber can be bonded together more firmly, effectively improving the bonding strength between ceramic nails and rubber;
