Abstract

The invention discloses a pre-dispersed masterbatch particle carrier. The pre-dispersed masterbatch particle carrier comprises the following raw materials in parts by mass: 5-90 parts of rubber, 1-10 parts of stearic acid, 1-10 parts of pentaerythritol aliphatic ester, 2-10 parts of an ethylene vinyl acetate copolymer EVA and / or EVM and 0.1-10 parts of a polar plasticizer. The components are cooperatively used to form a heat softening carrier system with high compatibility and can be mixed with liquid active components, powdery active components and granular active components at the temperature of not more than 55 DEG C, and the active components can achieve excellent dispersion and distribution effects. The problems of sublimation, volatilization, reaction and failure of the active components caused by over-high pre-dispersion mixing temperature are avoided; the active components are uniformly dispersed in masterbatch particles in the absence of aggregates, so that the active components can be uniformly dispersed in a rubber system in the production process of followed rubber products to form high-performance rubber products.

Description

technical field [0001] The invention relates to a rubber additive, in particular to a pre-dispersed master rubber particle carrier, a pre-dispersed master rubber particle prepared by using the carrier, and applications of the carrier and the master rubber particle. Background technique [0002] Various additives are needed in the production process of rubber products, such as rubber vulcanizing agent, rubber peroxide crosslinking agent, rubber peroxide crosslinking aid, rubber accelerator, rubber anti-aging agent, rubber filler and reinforcing agent, Rubber plasticizer or softener, phenolic resin, hydrocarbon resin, rubber adhesion promoter, rubber foaming agent, rubber pigment, rubber colorant, etc. In the traditional industry, the above-mentioned various additives are generally in the form of powder or liquid. When the powder is added to the rubber mixing system, it is easy to cause the powder of the additive to fly, causing dust pollution to the environment, and it is not...
