Abstract
The invention discloses a surface treating agent for metal die castings. The surface treating agent comprises, by weight, 100 parts of phosphoric acid, 15 to 25 parts of alkyd resin, 5 to 10 parts of urea resin, 15 to 20 parts of ammonium chloride, 100 to 120 parts of deionized water, 5 to 10 parts of a mixed alcohol solvent and 1 to 3 parts of a surface active agent. The mixed alcohol solvent is a mixed solvent of ethyl alcohol and ethylene glycol. By the adoption of the treating agent, the very good corrosion prevention and rust prevention effects on the metal die castings can be better achieved, cleaning of the surfaces of the castings can be enhanced through adding of the ammonium chloride, the bonding force of a corrosion prevention film layer can be enhanced through the cooperation of the alkyd resin and the urea resin, and the coating and attaching force is enhanced.
Description
Technical field
The present invention relates to a kind of metal crimp casting surface treatment agent.
Background technology
The main purpose of Treatment of Metal Surface improves the Corrosion Protection of metal material.Utilize simple, safe method to carry out Treatment of Metal Surface, be the target that people pursue always.But the large multipair environmental hazard of existing surface treatment method surface conditioning agent used is heavier, as containing cerium Se, chromium Cr, copper Cu etc., and market seldom has specially towards the surface cleaning agent of metal crimp foundry goods, major part just can only simply degreasing or rust cleaning, cannot clean aluminium alloy compression casting coating and remove.Traditional alloy surface cleaning agent has been difficult to the requirement meeting aluminum current alloy pressuring casting surface clean.Although application number surface conditioning agent environmental protection disclosed in the Chinese patent of 201010147481.0, poor to the surface treatment capabilities of metal casting, rete is antirust need further raising with Corrosion Protection.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of metal crimp casting surface treatment agent.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of metal crimp casting surface treatment agent, counts by weight, composed of the following components:
Phosphatase 11 00 part, alkyd resins 15-25 part, Lauxite 5-10 part, ammonium chloride 15-20 part, deionized water 100-120 part, mixed alcohol solvent 5-10 part, surfactant 1-3 part; Described mixed alcohol solvent is the mixed solvent of ethanol and ethylene glycol.
Preferably, described surface conditioning agent is composed of the following components:
Phosphatase 11 00 part, alkyd resins 20 parts, Lauxite 8 parts, ammonium chloride 15 parts, deionized water 100 parts, mixed alcohol solvent 8 parts, 2 parts, surfactant; Described mixed alcohol solvent is the mixed solvent of ethanol and ethylene glycol.
Preferably, described alkyd resins is epoxy resin modification alkyd resins.
Preferably, described epoxy resin modification alkyd resins method is: first synthetic epoxy resin, then by epoxy resin and the blended obtained epoxy resin modification alkyd resins of polymerization inhibitor, promoter and alkyd resins.
Preferably, the volume ratio of described ethanol and ethylene glycol is: 1:1.2-1.5.
Preferably, described surfactant is nonionic surface active agent.Further preferably, described nonionic surface active agent is polyethylene glycol series or APES series of surfactants
The beneficial effect that the present invention reaches:
Inorganic agent of the present invention more can play extraordinary anticorrosion, corrosion protection to metal crimp foundry goods, and the interpolation of ammonium chloride can strengthen the cleaning to cast(ing) surface, and alkyd resins and Lauxite can assist the adhesion strengthening anticorrosion rete, strengthens application adhesive force.
Detailed description of the invention
Below in conjunction with specific embodiment, the invention will be further described.Following examples only for technical scheme of the present invention is clearly described, and can not limit the scope of the invention with this.
Embodiment one
Prepare inorganic agent by approach well known, following component is all with weight parts:
Phosphatase 11 00 part, epoxy resin modification alkyd resins 25 parts, Lauxite 10 parts, ammonium chloride 20 parts, deionized water 120 parts, mixed alcohol solvent 10 parts, nonionic surface active agent 3 parts; Described mixed alcohol solvent is the mixed solvent of ethanol and ethylene glycol.Wherein, the volume ratio of ethanol and ethylene glycol is: 1:1.3.
Wherein, alleged epoxy resin modification alkyd resins method is: first synthetic epoxy resin, then by epoxy resin and the blended obtained epoxy resin modification alkyd resins of polymerization inhibitor, promoter and alkyd resins.
Embodiment two
Prepare inorganic agent by approach well known, following component is all with weight parts: phosphatase 11 00 part, epoxy resin modification alkyd resins 15 parts, Lauxite 5 parts, ammonium chloride 15 parts, deionized water 100 parts, mixed alcohol solvent 5 parts, polyethylene glycol series of surfactants 1 part; Described mixed alcohol solvent is the mixed solvent of ethanol and ethylene glycol, and wherein, the volume ratio of ethanol and ethylene glycol is: 1:1.2.
Described epoxy resin modification alkyd resins method is: first synthetic epoxy resin, then by epoxy resin and the blended obtained epoxy resin modification alkyd resins of polymerization inhibitor, promoter and alkyd resins.
Embodiment three
Prepare inorganic agent by approach well known, following component is all with weight parts:
Phosphatase 11 00 part, epoxy resin modification alkyd resins 20 parts, Lauxite 8 parts, ammonium chloride 15 parts, deionized water 100 parts, mixed alcohol solvent 8 parts, APEO series of surfactants 2 parts; Described mixed alcohol solvent is the mixed solvent of ethanol and ethylene glycol, and wherein, the volume ratio of ethanol and ethylene glycol is: 1:15.
Described epoxy resin modification alkyd resins method is: first synthetic epoxy resin, then by epoxy resin and the blended obtained epoxy resin modification alkyd resins of polymerization inhibitor, promoter and alkyd resins.
Comparative example one
Each component and content, with embodiment three, are not uniquely both and do not use epoxy resin modification alkyd resins, Lauxite use amount is increased to 28 parts simultaneously.
Performance test:
With the casting surface treatment agent that embodiment 1-3 and comparative example one obtain, sample cast(ing) surface is sprayed, flooded, then by eliminate rust after standard GB/T 11376-97 " the phosphate conversion film of metal " and GB6807-86 " before iron and steel parts japanning phosphorization treatment technology condition " check processing performance, Corrosion Protection and application adhesive force, the results are shown in following table:
