Abstract
The invention provides a finishing agent for metal surface protection, which is a mixture prepared by the following components by weight parts in each liter of mixture: 13-50 g of silane coupling agent KBM403, 1-3g of phytic acid, 1.5-9g of triethanolamine, 0.2-0.4g of sodium molybdate, 3-8g of sodium silicate, 95-105g of ethanol and the balance water. A metal piece is processed by the finishing agent, so that a film layer formed on the surface of the metal has the characteristics of strong adhesive force, compactness, uniformity and small polarization current density, the defects of preprocessing of the surface of the existing metal are improved, and technologies of preprocessing the surface of the metal, substituting for phosphating and blackening can be applied better. At the same time, a production process and a use process are environmental-friendly without pollution.
Description
Technical field
The present invention relates to field of metal surface treatment, be specifically related to a kind of protecting metallic surface treatment agent.
Background technology
In field of metal surface treatment; Though traditional phosphate conversion and chromating process for treating surface can obtain good effect; But contain carcinogenic substances such as heavy metal ion such as zinc, manganese, nickel, chromium and nitrite in the waste liquid of discharging in the treating processes, environmental pollution is very serious.And the metallic surface silanization treatment technology is not owing to relate to environmentally hazardous material, and energy consumption in production process is low, technical applications is extensive, be considered to be expected to replace phosphate conversion handle and the chromating processing, and be that the metallic surface is protected the recent development direction separately.
Summary of the invention
The invention discloses a kind of protecting metallic surface treatment agent, adopt silanization treating agent to handle metal works, form the polyacid rete on the surface; This rete has strong adhesion, do not have the cavity, split sunken, evenly fine and close; The characteristics that polarized current density is little, and production process environmental protection, pollution-free.
The technical scheme that adopts for the present invention of realization above-mentioned purpose is following:
A kind of protecting metallic surface treatment agent, by the formulated mixed solution of following component, the weight part of each component is in every liter of mixed solution:
Silane coupling agent KBM403 13-50g
Phytic acid 1-3g
Trolamine 1.5-9g
Sodium orthomolybdate 0.2-0.4g
Water glass 3-8g
Alcohol 95-105g
Surplus is a water.
Described protecting metallic surface treatment agent, by the formulated mixed solution of following component, the weight part of each component is in every liter of mixed solution:
Silane coupling agent KBM403 20g
Phytic acid 2g
Trolamine 5g
Sodium orthomolybdate 0.3g
Water glass 5g
Ethanol 100g
Surplus is a water.
Process for preparation is following:
1), absolute ethyl alcohol and deionized water mixing and stirring; Being mixed with concentration is 10% ethanolic soln, then silane coupling agent KBM403 is added wherein, uses the pH value of glacial acetic acid, manganese hydrogen sodium regulating solution to be 8-10; Stirring is hydrolyzed into solution clarification, transparent, obtains solution A;
2), phytic acid is mixed by formula rate with trolamine, isothermal reaction certain hour under 40-50 ℃ of condition obtains solution B;
3), water glass mixes by formula rate with Sodium orthomolybdate, constant temperature 80-90 ℃ reaction obtains solution C under acidic conditions;
4) solution A, B, three kinds of solution of C are mixed, use the pH value of manganese hydrogen sodium regulating solution to be 8-10, constant temperature 50-60 ℃ reaction promptly obtains treatment agent of the present invention.
Beneficial effect of the present invention:
With treatment agent of the present invention place metal works, the rete that forms in the metallic surface has following character:
(1) strong adhesion of rete: at when preparation at first phytic acid and trolamine condensation reaction generation hydramine phytate; The silicon-molybdenum heteropoly acid that molybdate and silicate reaction generate; Hydramine phytate and silicon-molybdenum heteropoly acid form hydramine phytate-silicon-molybdenum heteropoly acid rete, the hydramine phytate-silicon-molybdenum heteropoly acid rete of gained and the strong adhesion of metallic matrix then;
(2) this hydramine phytate-silicon-molybdenum heteropoly acid rete is evenly fine and close; Defectives such as the hole that traditional silicon alkanisation processing rete exists, crack have been overcome; This rete can overcome traditional silylanization effectively and handle defectives such as the hole of rete existence, crack, has strengthened the erosion resistance of metallic surface;
(3) this rete polarized current density is less, has very strong insulativity;
(4) this rete has strengthened the sticking power of later stage application paint film and metal body;
(5) production of the present invention and treating processes environmental protection are pollution-free.
Therefore this product can fundamentally improve the pretreated deficiency in existing metallic surface, thereby can the pre-treatment of better application metallic surface, substitutes phosphatization, black-emitting technology.
