Abstract
The invention discloses a metal rustproof protective agent and a preparation method thereof. The protective agent is prepared by emulsification of a wax substance, synthetic resin, fatty acid, fatty amine, a metal corrosion inhibitor, a surfactant, a preservative and water according to a specific ratio. The preparation method includes: preparing an aqueous substance and an oil phase substance respectively, and then conducting mixing dispersion emulsification, thus obtaining the final metal rustproof protective agent. With the characteristics of convenient coating and strong adhesion, the metal rustproof protective agent is easy to clean during metal sheet after-treatment, and is a green and environment-friendly type rustproof protective agent. The rustproof protective agent still has good adhesion at high temperature, can be repeatedly heated for use during coating metals, foils and other metal mechanical equipment parts, and overcomes the defect that ordinary emulsion products or common anti-rust oil products are unable to coat or difficult to coat at high temperature.
Description
Technical field

The short-term rust prevention protection of part, plant equipment object.
Background technology
Various cold rolling, hot rolling iron and steel sheet and plates, some metal foils and some plant equipment are very fast to prevent after completing
Corrosion is produced, and typically one layer of rust-inhibiting materials will be applied on its surface, corrosion not occurred using front to protect metal, affecting its matter
Measure and be worth, on the other hand the protective layer can also play certain protective action to metal surface, prevent slight scuffing.At present
The short-term rust prevention of metallic plate, foil and steel machinery part of appliance is all to apply one layer of antirust oil or rust-proofing wax material.Though antirust oil
There is good short-term rust prevention effect.But it is oily matter, when front cleaning treatment is used in the later stage, the pollution of meeting generation environment, is this
People have carried out the research and development of water-based antirust, and water-based antirust is not typically contained or few oiliness material, and cleaning treatment is easy
Convenient, the waste water of generation is few and disposable.Thus water-base metal antirust agent is the widely studied problem in the field over recent year,
The new product and new technique of invention also compares many.CN1386812A discloses a kind of antirust liquid wax for automobile, and the patent is used
Traditional method, dissolves various required compositions with solvent naphtha, and although product has certain rustless property, but due to containing solvent naphtha,
There is solvent odor during use, there is defect disagreeableness to environment.CN1488699A discloses a kind of water-based metal antirust
Protective agent, due to barium mahogany sulfonate composition used in product, makes the product have certain toxicity.CN101104774A discloses one
Metal rust-proofing wax is planted, with Wax as main basic substance, the protecting film of product does not have toughness.CN1386812A discloses one
Antirust agent is planted, main component is petroleum wax substance and petroleum solvent, rustless property and other performance existing defects, and to environment
It is unfriendly.
The content of the invention
For the deficiencies in the prior art, the invention provides a kind of rust-proof effect is good, smear adhesion in metal surface holding
Easily, and it is easy to environment-friendly type metal antirust protective agent of metal cleaning treatment and preparation method thereof.
