The invention discloses a mute hub which comprises a rim and a sound-absorbing sponge, and the sound-absorbing sponge is attached to the surface of the rim through tire pressure-sensitive adhesive. The tire pressure-sensitive adhesive is prepared from the following ingredients in percentage by mass: 5 to 10 percent of antioxidants, 5 to 15 percent of plasticizers, 10 to 30 percent of 2-ethylhexyl acrylate, 10 to 30 percent of toluene diisocynate, 20 to 35 percent of acetic ether and 15 to 30 percent of butyl acrylate. The sound-absorbing sponge is attached to the surface of the rim through the tire pressure-sensitive adhesive, the tire pressure-sensitive adhesive mainly comprises the antioxidant, the plasticizer, the 2-ethylhexyl acrylate, the toluene diisocynate, the acetic ether and the butyl acrylate, the tire pressure-sensitive adhesive has good adhesion and plasticity, the glue is not prone to hardening, and the tire pressure-sensitive adhesive is not prone to deformation. And the sound-absorbing sponge does not fall off from the rim due to hardening, glue failure and aging of the glue.
本发明公开了一种静音轮毂,包括轮辋和吸音海绵,所述吸音海绵通过轮胎压敏胶贴附在所述轮辋的,表面,所述轮胎压敏胶包括以下质量比成分:抗氧剂5‑10%、抗塑剂5‑15%、丙烯酸异辛酯10‑30%、甲苯二异氰酸酯10‑30%、醋酸乙酯20‑35%和丙烯酸丁酯15‑30%。本发明的吸音海绵通过轮胎压敏胶贴附在轮辋的表面,轮胎压敏胶主要包括抗氧剂、抗塑剂、丙烯酸异辛酯、甲苯二异氰酸酯、醋酸乙酯和丙烯酸丁酯,轮胎压敏胶具有良好的粘附性和可塑性,胶水不容易变硬,使吸音海绵不会因为胶水变硬开胶老化而从轮辋上脱落。
