The present invention relates to a multiple anti-vibration pad and a method for manufacturing an anti-vibration pad, wherein the anti-vibration pad has a structure in which a first pad and a second pad having different physical properties are stacked. To form the first pad and the second pad, natural rubber (NR) or ethylene-propylene rubber (EP), liquid isoprene rubber (LIR) or chloroprene rubber (CR), carbon black SRF (Semi-reinforcing Fumace Balck), calcium carbonate (cac03), compounded oil, zinc oxide (ZnO), stearic acid (S/T), M (MBT: 2-Mercapto benzo thiazole) of thiazole-based accelerators, TT (TMTD: Tetramethylthiuram Disulfide) of thiuram-based accelerators, sulfur (S), and cerium (CE) may be mixed. The anti-vibration pad of the present invention having the above-described components and structure is excellent in reducing external impact and vibration, has a small compression set, and has excellent aging resistance and heat resistance.

Номер: KR101861073B1
Автор: YANG, CHEL WOO
Принадлежит: YANG, CHEL WOO

The present invention relates to a water-swelling rubber waterstop. The waterstop can come in contact with moisture to be expanded in a state of being inserted into a joint between primarily applied concrete and secondarily applied concrete so as to prevent leakage into the joint. To this end, according to the present invention, the water-swelling rubber waterstop comprises: a waterstop body (11) having a rubber material expanded when absorbing moisture and having a bar shape with predetermined length; and a protruding pad (12) having the rubber material expanded when absorbing moisture and integrally protruding from an outer surface of the waterstop body (11).

Принадлежит: YANG, CHEL WOO

The present invention relates to a water-expandable rubber ring to connect a Hume pipe, which is extended in a longitudinal direction and is installed in a connection part of the home pipe to be used for socket joint, and a manufacturing method thereof. According to one embodiment of the present invention, the water-expandable rubber ring to connect a Hume pipe is manufactured by forming a rubber ring made through a unique mixing ratio and process, and comprises: an inclined surface inclined at a predetermined angle from a lower surface; a slit groove disposed on the upper surface and extended in a longitudinal direction; a protecting step disposed between the slit grooves and extended in the longitudinal direction of the slit groove; a lower slit disposed on the lower surface and formed to repeat a wave pattern arrangement; and a through-hole having an inner part penetrated in parallel to the longitudinal direction of the slit groove. Accordingly, water tightness in Hume pipe joint is ...
