The invention relates to a self-foaming sound-absorbing sponge tire, and belongs to the field of tires. Comprising a tire body and a sound absorption part. The tire body comprises a tread, a sidewall, an airtight layer and the like; and the sound-absorbing part is formed by applying a polyurethane foaming material on an airtight layer of the inner cavity of the tire, automatically foaming and expanding in the air, and crosslinking and curing, so that the sound-absorbing sponge tire is finally obtained. The manufacturing method comprises the following steps: firstly, carrying out laser cleaning on an inner cavity airtight layer of the tire; then, the airtight layer is coated with a polyurethane foaming material, automatic foaming expansion and cross-linking curing are carried out in the air, standing is carried out, and the sound-absorbing sponge tire is obtained. The invention aims to provide the self-foaming sound-absorbing sponge tire, the tire has good sound-absorbing performance, the production process is simple, the efficiency is high, and the foaming material has excellent durability.

    本发明涉及一种自发泡吸音海绵轮胎,属于轮胎领域。包括轮胎本体和吸音部两部分。轮胎本体包括胎面、胎侧、气密层等部位;吸音部是由聚氨酯发泡材料施于轮胎内腔的气密层上,在空气中自动发泡膨胀并交联固化,最终得到吸音海绵轮胎。本发明的制造方法如下:首先,激光清洗轮胎内腔气密层;然后,将聚氨酯发泡材料涂覆在气密层上,在空气中自动发泡膨胀并交联固化,静置制得吸音海绵轮胎。本发明旨在提供一种自发泡吸音海绵轮胎,轮胎具有良好的吸音性能同时生产工艺简单效率高,发泡材料耐久优良。
