Ethylene-propylene rubber particles of active hydrogen-containing compound, and production method thereof

Abstract

The present invention discloses ethylene-propylene rubber particles of an active hydrogen-containing compound, and a production method thereof. The ethylene-propylene rubber particles comprise color master batch of an active hydrogen-containing compound, a reinforcing agent comprising an active hydrogen bond-containing nanometer reinforcing agent and a reinforcing agent, and an activator material. The production method comprises: preparing color master batch, wherein an active hydrogen-containing compound is added to a pigment, a color master batch carrier and an anti-ultraviolet ray agent are added, complete dispersion and mixing are performed, and extrusion granulation is performed through an extruder; preparing a reinforcing agent material and an activator material; and preparing ethylene-propylene rubber color particles, wherein a vulcanizing agent is added to the color master batch while the reinforcing agent material, the activator material, an accelerator, a plasticizer and an anti-aging agent are added, opening type mixing and sealed mixing are performed through a roll mill, the obtained material enters a vulcanizing cylinder to be subjected to a vulcanizing treatment to prepare a vulcanizing film, and the vulcanizing film is broken. The ethylene-propylene rubber particles have characteristics of good cross-linking strength with the polyurethane adhesive, strong ultraviolet ray resistance, and bright color.

Description

technical field [0001] The invention relates to a rubber particle with high elasticity, high strength and good anti-ultraviolet effect and a production method, in particular to an ethylene-propylene rubber particle containing an active hydrogen compound. Background technique [0002] Ethylene-propylene rubber is obtained by copolymerizing monoolefin ethylene and propylene into binary ethylene-propylene rubber; ethylene-propylene rubber is obtained by copolymerizing ethylene, propylene and a small amount of non-conjugated diene as monomers. On the molecular main chain of ethylene-propylene rubber, ethylene and propylene monomers are arranged randomly, losing the regularity of polyethylene or polypropylene structure, thus becoming an elastomer. Since the diene of EPDM rubber is located on the side chain, the three Ethylene-propylene-diene rubber can not only be vulcanized with sulfur, but also maintain various characteristics of ethylene-propylene-diene monomer.

Problems solved by technology

[0010] Ethylene-propylene rubber is a saturated non-polar polymer, and its adhesion to polyurethane adhesives is relatively weak, especially for making sports venues, which are generally operated at room temperature, so ethylene-propylene rubber particles and polyurethane adhesives The tear strength is low, the color (including fuel) powder is easy to free from the surface of the ethylene propylene rubber, and it is easy to fade under the action of ultraviolet rays

In the prior art, only by increasing the third elastomer content of EPDM rubber to increase the adhesive strength of the polyurethane adhesive, this method has high cost, low efficiency, especially the low anti-ultraviolet ability of the particles, and the three-component Ethylene propylene rubber particles are easy to fade
