Abstract

The invention discloses a compound multifunctional rubber processing peptizer and a preparation method thereof. The compound multifunctional rubber processing peptizer comprises the following raw materials in parts by weight: C8-C22 fatty acid, indirect method zinc oxide, an anti-oxidant, a metal bonding enhancing agent and metalloporphyrin. The preparation method for the compound multifunctional rubber processing peptizer particularly comprises the following steps: taking the raw materials, adding fatty acid, the metal bonding enhancing agent, metalloporphyrin and the anti-oxidant, adding indirect method zinc oxide, performing vacuum pumping, pelleting, packaging and testing for storage. Through the adoption of the compound multifunctional rubber processing peptizer taking activated fatty acid zinc soap as a carrier, the mooney viscosity of raw rubber can be quickly reduced during the plastication through an open mill or an internal mixer, so that the plastication efficiency is improved, energy consumption of equipment is reduced, and the excellent peptizing effect is realized; in addition, the compound multifunctional rubber processing peptizer has the functions of improving the mobility of a sizing material, accelerating the mixing of blended rubber, activating the vulcanized size material, resisting to reversion and abrasion, and preventing SBR ring structuring.

Description

technical field [0001] The invention relates to a composite multifunctional rubber processing aid, in particular to a composite multifunctional rubber processing peptizer and a preparation method thereof. Background technique [0002] Rubber peptizers are divided into chemical peptizers and physical peptizers. The chemical peptizer generates free radicals under the action of thermal oxygen, cuts off the long chains of rubber molecules, and combs the entangled molecular chains, thereby achieving the effect of plasticizing. Chemical peptizers can shorten the time of mastication and improve the efficiency of mastication. However, the chemical peptizers pentachlorothiophenol used in China will pollute the environment and have been eliminated internationally. With the development of rubber processing technology, composite peptizers emerge as the times require, and their composition generally includes chemical peptizers, physical peptizers, activators, organic or inorganic disper...
