Abstract
The present invention relates to lubricating grease for non-adhesive prestressed reinforcement, which has the following components of 1 to 15 wt% of soap-based thickening agent, 1 to 8 wt% of mineral wax with C 20 to 50, 0.1 to 2 wt% of antioxidant and mineral oil as the rest on the basis of the weight of base oil. The waterproof mineral wax is added to the lubricating grease in order to obviously enhance the anti-rust performance of the lubricating grease and satisfy the operating requirement for the long service life of non-adhesive prestressed reinforcement. If rust inhibitors are added into the lubricating grease, the performance of corrosion resistance and rust resistance is further enhanced. If inorganic calcium salt is added into the lubricating grease, extreme pressing antiwear performance can be greatly improved.
Description
The invention belongs to lubricant, exactly is a kind of lubricating grease that is used for the building trade no-cohesive prestressed reinforcement.
Non-cohesive Prestressing Force Technology is the advanced technology of building trade, originates from the fifties, and the eighties is greatly developed.The anticorrosion problem of no-cohesive prestressed reinforcement is to influence the prestressing without bondn building key factor in work-ing life, so anticorrosion, the antirust and extreme pressure and antiwear behavior of no-cohesive prestressed reinforcement lubricating grease is most important.At present, commercially available anticorrosion fat generally is made up of mineral oil, fatty acid lithium basis soap, sulfonated petro-leum and amine antioxidants, after this lubricating grease used through eight, nine years, just become dry, the oxidation stability variation, it is big that acid number becomes, and therefore can not satisfy the long-life service requirements of no-cohesive prestressed reinforcement.
Foreign literature JP03119097 report is made viscosifying agent with polyureas, preparation no-cohesive prestressed reinforcement lubricating grease, but, do not see extensive application because of cost is too high.
The object of the present invention is to provide a kind of with low costly, can satisfy the lubricating grease of no-cohesive prestressed reinforcement service requirements.
Lubricating grease provided by the invention has following composition, is benchmark with base oil weight, and soap base viscosifying agent content is 1～15 heavy %; The ground wax content of carbon number 20～50 is 1～8 heavy %; Antioxidant content is 0.1～2 heavy %; Surplus is a mineral oil.
Wherein the soap base viscosifying agent can be lithium basis soap or lithium calcium basis soap etc., as 12-oxystearic acid lithium soap, and lipid acid lithium soap or hydroxy fatty acid lithium calcium soap, preferred stearic acid or lipid acid lithium soap.The consumption of viscosifying agent is 1～15 heavy % of base oil weight, preferred 5～12 heavy %.
Described cereous carbonatoms is 20～50, and is preferred 30～45, as No. 70 and No. 80 ceresine.Cereous effect is the anti-water permeate that strengthens lubricating grease, thereby improves the antiseptic and rustproof ability of lubricating grease.Cereous content is 1～8 heavy % of base oil weight, preferred 3～6 heavy %.
Described oxidation inhibitor is the general oxidation inhibitor in this area, can be amine type oxidation inhibitor or phenol type antioxidant, also can be the mixture of amine type or phenol type.Wherein phenol type antioxidant mainly comprises 2,6-di-t-butyl-4-cresols, 2,4-dimethyl-6 tert-butyl phenol, 2,6-di-tert-butylphenol and tertiary butyl mixed phenol etc.Amine type oxidation inhibitor mainly is pentanoic and to di-iso-octyldiphenylamine.Preferred amines type oxidation inhibitor.The consumption of oxidation inhibitor is 0.1～2 heavy % of base oil weight, preferred 0.2～0.6 heavy %.
Described base oil is a mineral oil, paraffin base mineral oil preferably, and 100 ℃ of viscosity are 10～15mm
2/ S.
In the lubricating grease provided by the invention, can also add rust-preventive agent with its rustless property of further raising.Said rust-preventive agent can be sulfonated petro-leum, nonyl naphthalene barium sulfonate, alkenyl succinic acid or petroleum oxidate wax barium soap etc.The consumption of rust-preventive agent can be 0.5～5 heavy % of base oil weight, preferred 1～3 heavy %.
Can also add inorganic calcium salt in the lubricating grease provided by the invention,, overcome no-cohesive prestressed reinforcement in the life-time service process, because the etching problem that fretting wear causes to strengthen its extreme pressure and antiwear behavior.Described inorganic calcium salt is selected from lime carbonate, calcium phosphate, secondary calcium phosphate, monocalcium phosphate or lime borate, also can be to be selected from the wherein mixture of two or more material arbitrary proportion, preferred lime carbonate, calcium phosphate, secondary calcium phosphate and monocalcium phosphate, most preferably lime carbonate.The consumption of inorganic calcium salt is 1～10 heavy % of base oil weight, preferred 5～8 heavy %.
Lubricating grease provided by the invention prepares according to a conventional method, promptly earlier viscosifying agent, part base oil are mixed, be warming up to 70～90 ℃, add alkaline solution and carry out saponification reaction, be warming up to 190～210 ℃ again and stop heating, add the surplus base oil, add various additives in the temperature-fall period, stirring gets final product.
Owing to added ceresine, the rustless property of lubricating grease is significantly improved in the lubricating grease provided by the invention, satisfied long-life service requirements of no-cohesive prestressed reinforcement with anti-water permeate.For example, adopt lubricating grease of the present invention after, the salt fog cabinet test-results rises to the B level from the D level of common fat, the humidity cabinet test result rises to 0 grade from 1 grade of common fat.
If add rust-preventive agent in lubricating grease provided by the invention, then antiseptic and rustproof performance further improves, and salt-fog test can reach the A level.If add inorganic calcium salt again, then extreme pressure and antiwear behavior can improve greatly, P
BValue can increase 500～800N, and fraze can reduce 0.15～0.4mm.
