본 발명은 고무-실리카 배합시 커플링제로 사용되는 네트워크용 계면 고분자에 관한 것으로서, 더욱 상세하게는 공역디엔과 비닐방향족 모노머로 이루어진 공중합체를 포함하는 블록공중합체로서 이를 합성 고무와 무기소재인 실리카와의 배합 시 커플링제로 사용할 경우 고무 내에 실리카 분산성이 좋아져 상용성 및 가공성이 향상되므로 고무의 기계적 물성뿐만 아니라 동적 물성을 크게 향상시켜서 타이어 등에 적용시 자동차 제동 성능의 개선 및 회전저항을 감소시키는 고무-실리카 네트워크용 계면 고분자에 관한 것이다.
摘要:
The present invention relates to styrene-butadiene rubber gel which a functional monomer is introduced and more specifically, to a compound with characteristics of high wear resistance, wet skid resistance, and low rolling resistance in a silica compound which is obtained by radical polymerizing styrene monomer, butadiene monomer, and glycidyl methacrylate monomer in an emulsion state; maximizing the polarity of the resultant product by a ring opening reaction of copolymers consisting of glycidyl methacrylate and styrene-butadiene; and chemically cross-linking the resultant product.

The present invention relates to an interfacial polymer for a network being used as a coupling agent and, more specifically, to an interfacial polymer for a rubber-silica network. The interfacial polymer for a rubber-silica network which is a block copolymer including a copolymer consisting of a conjugated diene vinyl aromatic monomer improves silica dispersity in rubber, thereby improving compatibility and processability and remarkably improving the dynamic physical properties and mechanical properties, thereby improving braking and reducing the rotary resistance.

The present invention relates to a method of producing metal-ionomer from benzyl methacrylate styrene-butadiene elastomer, and thermo-reversible crosslinking elastomer containing the metal-ionomer. The elastomer which has excellent mechanical sensitive quality and is recyclable is synthesized and produced by using the metal-ionomer having self-combination properties, and the elastomer can be applied to environment friendly materials which has many human contacts including real life materials, spare parts of a vehicle, and interior materials for a vehicle.

PURPOSE: A manufacturing method of fiber for rubber reinforcement by three staged impregnation is provided to enhance adhesion to a raw rubber of fiber for rubber reinforcement applying triple dip system and to have high initial adhesive strength. CONSTITUTION: A production method of fiber for rubber reinforcement by three staged impregnation comprises a first impregnation step which dries and treats with heat after impregnating fiber of rubber reinforcement into a first treatment liquid with isocyanate; a second impregnation step which dries and treats with heat after impregnating the fiber for rubber reinforcement into a second treatment liquid with epoxy; and a third impregnating treatment which dries and treats with heat after impregnating the fiber for rubber reinforcement into a third treatment liquid. The third treatment liquid is a resorcinol formaldehyde latex adhesive liquid produced mixing a carboxylic nitrile butadiene rubber (XNBR) latex with resorcinol-formaldehyde (RF) initial condensate. A reinforced rubber complex is a production which the fiber for rubber reinforcement is attached on a raw rubber. Diaphragms for a compressed natural gas (CNG) controller or a liquefied natural gas (LNG) controller use the reinforced rubber complex.

A rubber composition for a tire tread is provided to improve abrasion resistance, mileage and wet traction and to enhance the interaction of a rubber molecule and an organically modified clay. A rubber composition for a tire tread comprises 100.0 parts by weight of a synthetic rubber; a reinforcing material which comprises 1~65 parts by weight of carbon black, 1~65 parts by weight of silica and 1~10 parts by weight of an organically modified clay; and rubber additives which contain 0.1~5 parts by weight of a metal stearate as a crosslinking accelerator. The organically modified clay is the clay which is organically modified by using a compound containing an alkyl ammonium salt or by using an alkylamine and an acid such as sulfuric acid, hydrochloric acid, etc. as a modifier to the laminated structure clay; and the metal stearate is one selected from calcium stearate, magnesium stearate, potassium stearate, and zinc stearate.
