Water-swelling rubber composite material, and preparation method and application thereof
2013
The invention discloses a water-swelling rubber composite material. The rubber composite material is formed from the following components in parts by weight: 100 parts of rubber, 30-100 parts of super adsorbent resin, 2-10 parts of metal ion sealing agent, 0.5-2.5 parts of solid softening agent, 0.5-3.5 parts of coloring agent, 1-7 parts of anti-aging agent, 1-7 parts of accelerant, 1-8 parts of zinc oxide, 5-45 parts of reinforcing agent, 5-20 parts of plasticizer, 0.1-2.6 parts of vulcanizing agent, and 5-45 parts of mixture of PEG (polyethylene glycol) and MDI (diphenylmethane diisocyanate) at a molar ratio of 1:1. The invention further provides a preparation of the rubber composite material, in particular provides an application of the rubber composite material as superfine rubber swelling particles in a large pore path or high-permeability belt of a reservoir deep strata for profile control and water shutoff of an oil-water well.
