Abstract

The present invention relates to a wearability-increasing type hemp-core grease composed of polyisobutylene, extractive oil of petroleum residue, 210 rosin-modified phenolic resin, high-pressure low-density polyethylene, dibutyl phthalate and T708 antirust agent. Said invented hemp-core grease is simple in prodn. process, possesses good rust preventive property and abrasion resistance, and its friction coefficient can be up to above 0.25.

Description

Enhancend friction type fiber core grease prescription and production technique

The invention belongs to chemical technology field, specifically, is a kind of wireline enhancend friction type fiber core grease.

At present, corrosion and the abrasion effect that alleviates wireline mainly worked in the fiber core grease of dip-coating when wireline closed rope, and its prescription and production technique kind are more.

The objective of the invention is to count to establish and a kind ofly have good rust protection, anti-friction and decrease the enhancend friction type fiber core grease that performance is good and have higher coefficient of friction.

Prescription of the present invention, its weight percent is: molecular weight is 600～1100 polyisobutene 25～37%, viscosity is extracted oil 35～50% out greater than 42 petroleum residue, 210 rosin modified phenolic resins 6～20%, hp-ldpe 3～15%, dibutyl phthalate 4～15%, T ₇₀₈Rust-preventive agent 0.1～3%.Production technique of the present invention is: at first get viscosity and extract oil 35～50% out greater than 42 petroleum residue, in water knockout, heat to 115 ℃ of deposition dehydratings, the dehydration back adds new LDPE (film grade) 3～15%, be heated to 130～150 ℃, stir after 6～10 hours, be cooled to 130 ℃, add 210 rosin modified phenolic resins 6～20% and dibutyl phthalate 4～15%6, insulation is stirred and circulating filtration at 130 ℃, adds T when cooling to 120 ℃ ₇₀₈Rust-preventive agent 0.1～3% stirs, and filters out still after the assay was approved, and packing gets final product.

The present invention compared with prior art decreases the performance except that having good rust protection, anti-friction, and its frictional coefficient can reach more than 0.25.

Enforcement of the present invention, its formulation selection is: molecular weight is 700 polyisobutene 31%, viscosity is extracted oil 45%, 210 rosin modified phenolic resin 12%, T out greater than 42 petroleum residue ₇₀₈Rust-preventive agent 1%, new LDPE (film grade) 6%, dibutyl phthalate 5%.Its blending process as described above.

Claims

1. an enhancend friction type fiber core grease that is made up of various chemical components is characterized in that, described formulation weight per-cent is:

Molecular weight is 600～1100 polyisobutene 25～37%, and viscosity is extracted oil 35～50%, 210 rosin modified phenolic resins 6～20%, hp-ldpe 3～15%, dibutyl phthalate 4～15%, T out greater than 42 petroleum residue ₇₀₈Rust-preventive agent 0.1～3%.

Its production technique is:

At first get viscosity and extract oil 35～50% out greater than 42 petroleum residue, in water knockout, heat to 115 ℃ of deposition dehydratings, the dehydration back adds hp-ldpe 3～15%, be heated to 130～150 ℃, stir after 6～10 hours, be cooled to 130 ℃, add 210 rosin modified phenolic resins 6～20% and dibutyl phthalate 4～15%, insulation is stirred and circulating filtration at 130 ℃, adds T when cooling to 120 ℃ ₇₀₈Rust-preventive agent 0.1～3% stirs, and filters out still after the assay was approved, and packing gets final product.
