High strength epoxy resin cis-polybutadiene composite material for hydraulic hammer high pressure oil pipes and preparation method thereof

Abstract

The invention discloses a high strength epoxy resin cis-polybutadiene composite material for hydraulic hammer high pressure oil pipes. The composite material is prepared from the following raw materials by weight: 100-110 parts of cis-polybutadiene, 11-12 parts of 4, 4'-diaminodiphenylmethane, 1.5-1.7 parts of N-cyclohexyl-2-benzothiazole sulfonamide, 2.5-2.8 parts of sulfur, 2-2.3 parts of stearic acid, 5-5.3 parts of zinc oxide, 40-42 parts of E-44 epoxy resin, 2-2.3 parts of nano tin antimony oxide, 2-2.5 parts of methyl methacrylate, 2.3-2.5 parts of nano boron fiber, 0.7-0.9 part of a silane coupling agent kh-550, and 0.8-1.2 parts of tetrapod-like zinc oxide whisker. Through use of nano boron fiber, the silane coupling agent kh-550 and tetrapod-like zinc oxide whisker, the tensile strength, tear strength, abrasion resistance and heat resistance of the rubber are improved.

Description

technical field [0001] The invention relates to the technical field of rubber materials, in particular to an epoxy resin butadiene rubber composite material for high-strength hydraulic breaker high-pressure oil pipes and a preparation method thereof. Background technique [0002] With the development of modern science and technology, people's requirements for the performance of polymer materials are becoming more and more diverse. It is often difficult for a single homopolymer and copolymer to meet various requirements. People begin to focus on using existing polymer materials to prepare them by blending methods. Multiphase composite materials with new functions can meet the new requirements of polymer materials in various industrial applications. In recent years, it has become a new field in polymer science to blend different types of polymers by physical or chemical methods to improve the properties of the original polymers or to form polymer blending systems with new prop...

AI Technical Summary

Problems solved by technology

[0005] Due to the large difference in solubility parameters between epoxy resin and butadiene rubber, the compatibility is poor, and the phase separation phenomenon is obvious, the addition of epoxy resin makes the fracture interface of the sample rough and uneven, and more holes are produced on the surface of the sample.
