Rubber layer material of drill hoses

Abstract

The invention discloses a rubber layer material of drill hoses. The rubber layer material is characterized in comprising following ingredients, by weight, 50 to 60 parts of natural rubber latex, 10 to 12 parts of crosslinked starch, 0.3 to 0.5 part of promoter TMTD, 3 to 5 parts of sulphur, 0.6 to 0.8 part of calcium stearate, 1 to 2 parts of zinc oxide, 1 to 2 parts of an anti-aging agent, 3 to 4 parts of a nano material, 3 to 5 parts of white carbon black, 0.4 to 0.6 part of titanium dioxide, 0.2 to 0.3 part of octadecyl imidazoline, 2 to 4 parts of argil, 0.4 to 0.6 part of a wetting agent, and 0.2 to 0.4 part of an organic pigment. Stability of the rubber layer material is improved; the rubber layer material possesses relatively excellent strength, extensibility, organic solvent corrosion resistance, and aging resistance, and is long in service life, and wide in application range.

Description

technical field [0001] The invention belongs to the technical field of rubber materials, and in particular relates to a rubber layer material of a drilling rubber hose. Background technique [0002] The chemical properties of natural rubber Natural rubber is unsaturated rubber, which is easy to undergo vulcanization reaction (structural reaction) with vulcanizing agent, oxidation and cracking reaction between bromine and oxygen, ozone, chlorination reaction with halogen, and occurs under the action of catalyst and acid chemical reaction etc. However, since natural rubber is a polymer compound, it has the reaction characteristics of olefinic organic compounds, such as slow reaction speed, incomplete and uneven reaction, and the phenomenon of coexistence of various chemical reactions (such as oxidative cracking reaction and structuring reaction) )Wait. [0003] Natural rubber has excellent comprehensive physical and mechanical properties Natural rubber has good elasticity at...

Problems solved by technology

[0006] At present, the rubber material of the drilling hose has the following problems: the storage stability is poor, the color of the product is not bright, and the pigment will not only deliquesce after being eroded by water. What's more serious is that the dispersion performance in the rubber medium is poor, which leads to insufficient color development of the pigment in the product. The main reason for this is the selection of liquid paraffin, which can easily absorb moisture in the air.
