Description
Technical field
The present invention relates to paint field, specifically a kind of surface treating composition for metallic substance, i.e. the elasticity rust proof paint of a kind of snappiness, good antirust property, excellent storage stability.
Background technology
In the environment such as seawater or high temperature/high humidity environment of saliferous, the surface that is coated with the steel of metal can form the rusty stain of white, causes the obvious outward appearance that worsens of substrate surface or the reduction of antirust ability.
Rust proof paint is industrial widely used a kind of coating, and its Main Function is to prevent that metal is subject to oxidation and gets rusty in the life-time service process.Rust-stabilising pigment component in the rust proof paint is generally the chromic salt of red lead, lead powder and zinc, lead or barium.These pigment have very strong toxicity, can serious environment pollutions in the production of coating and use procedure, and infringement is produced and is executed the healthy of lower operator.Therefore, many countries have all banned use of by legislation and have contained red lead, lead powder etc. and be coating material production and the use of rust-stabilising pigment component.
At present, people successively develop the rust proof paint with rust-stabilising pigment components such as zinc phosphate, aluminum phosphate, zinc molybdate, lime borates, and these coating have the low characteristics of toxicity, but rust-proof effect is bad, and the color development of film-forming resin and stability are not good enough yet.On the other hand, the rust proof paint of domestic production great majority are solvent based coating, and its solvent includes iron red alcohol acid, iron oxide red phenolic aldehyde, iron oxide red epoxy vinegar, iron oxide red epoxy, chlorosulfonated polyethylene etc.These coating are not only expensive, and contaminate environment very easily, and human body is damaged.
In addition, in the use procedure of rust proof paint, because the variation of temperature, humidity easily produces the crack, thereby accelerate the aging of coating, metal material surface is difficult to play rust-proof effect.Existing elastic coating can keep higher elasticity, toughness and elongation in certain temperature range, be coated on metal material surface and form the elastic protective layer, and coating can not rupture when cracking, and has preferably waterproofing and anti-leakage leakage property.But because present domestic main employing coal fired power generation, sulfur dioxide content in air is high, and each department acid rain takes place frequently, and atmospheric pollution is serious, causes elastic coating surface contamination and acid etching to destroy serious, and the ornamental and weather resistance of elastic coating is descended greatly.
CN 101402816A discloses a kind of water-based elastic paint for building exterior wall surface protection and decoration.Present elastic coating mainly focuses on the contamination resistance that solves elastic coating, and acid rain resistant and ageing-resistant aspect are seldom related to.The quality percentage composition of each component is as follows in the coating of the present invention: water 10-20%, solubility promoter 2-4%, dispersion agent 0.5-1.0%, multifunctional assistant 0.2-0.4%, defoamer 0.2-0.5%, sanitas 0.1-0.2%, mildew-resistant algaecide 0.2-0.6%, acidproof pigment 15-23%, acid resistance filler 5-18%, fluorine carbon emulsion 10-15%, acrylic elastic emulsion 30-40%, film coalescence aid 1-1.5%, auxiliary rheological agents 0.3-0.8%, thickening material 0.5-1.0%.This invention elasticity and ageing-resistant aspect performance better, but when being used for metal material surface, can not accomplish simultaneously antirust.
