CN104449998A - Protective antirust grease for sealing and preparation method of protective antirust grease - Google Patents

Abstract

The invention discloses protective antirust grease for sealing. The protective antirust grease is characterized by being prepared from the following raw materials in parts by weight: 8-10 parts of 50# machine oil, 12-15 parts of 20# aviation lubricating oil, 1-2 parts of glycerol monostearate, 35-40 parts of solid paraffin, 21-27 parts of vaseline, 6-8 parts of dodecencylsuccinic acid diethanolamide, 0.5-0.7 part of benzotriazole, 0.7-1 part of tributyl phosphate, 2-3.5 parts of laminar-crystallized sodium disilicate, 1-2 parts of superfine PMMA powder and 2.5-4 parts of a protective agent. The protective antirust grease is scientific and reasonable in formula; by adding a protective agent and such film forming components as the superfine PMMA powder, a firm absorbing film can be formed on the surface of metal, so that rusting caused by corrosion of water and oxygen is prevented, and the high temperature resistance and the fire resistance are achieved; the protective antirust grease is high in oil film strength, does not easily run off or volatilize, is excellent in rusting resistance, can well protect metal parts and is applicable to long-term sealing.

Description

A kind of there is provide protection seal up for safekeeping with rust preventing grease and preparation method thereof

Technical field

The present invention relates to rust protection liquid field, particularly a kind of there is provide protection seal up for safekeeping with rust preventing grease and preparation method thereof.

Background technology

Seal part up for safekeeping at the work in-process of plant produced or supporting warehouse-in, need to smear one deck rust-preventive agent above and prevent part from getting rusty, then wrap with waxed paper.So just can ensure metal non-corrosive over a period to come, existing slushing oil effect is general, the antirust cycle is shorter, the antirust of long term can not be carried out, and complicated operation, need heating during oil sealing, complicated operation and heat-resistant quality and anti-oxidative stability are difficult to reach requirement, and rust-proof life is shorter in the presence of a harsh environment.

The present invention is by research; invent a kind of grease type rust preventing oil; ointment shape; good water-proof effect, adds again the protective material of special development, flame-resistant high-temperature-resistant; heating is smeared or cold painting; quality product can not be caused to change, and rust-proof effect is first-class, has good corrosion protection effect to metal parts, fastening piece, work in-process.
