Abstract
The invention relates to the technical field of metal surface treatment, and in particular relates to a protective agent mainly used for the surface of a metal mold and a preparation method of the protective agent. The surface protective agent comprises the following component formulas in parts by weight: 11-24 parts of water-borne epoxy resin, 12-26 parts of mixed tung oil, 50-65 parts of ethyl acetate, 2-4 parts of sodium iso-octoate and 0.2-0.4 part of benzotriazole. The component formulas of the metal mold surface protective agent provided by the technical scheme of the invention are wide in raw material source, relatively low in cost and relatively high in drying speed, do not contain fluorine and chlorine elements in components, are safe and environment-friendly, can not influence the electrical conductivity, insulating properties and weldability of coating parts, and are suitable for the surface protection treatment of the metal mold. The preparation method provided by the technical scheme is relatively simple in process, is convenient and practical, and is suitable for popularization and application.
Description
Technical field
The present invention relates to a kind of field of metal surface treatment technology, specifically a kind of protective material that is mainly used in metal die surface and preparation method thereof.
Background technology
After metal is corroded, the aspects such as its profile, color and luster, electrical property and mechanical property all will change, and will cause the accidents such as damage of facilities, pipe leakage, product contamination.For this reason, need metallic surface be protected or be processed.At present, the technical scheme that addresses the above problem employing is generally in metallic surface, to apply coating or plating, thereby reaches the effect of protection.But in metallic surface, apply the problem of coating or plating existence mainly: the one, the poor adhesive force of coating, the time has been grown easily and has come off; The 2nd, coating coating or plating all can cause the problem of contaminate environment, can not meet the needs of product.Therefore, develop that a kind of starting material wide material sources, cost are lower, rate of drying faster the protective material and preparation method thereof on metal die surface be the current problem that will study.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiencies in the prior art, provide that a kind of starting material wide material sources, cost are lower, the rate of drying protective material and preparation method thereof on metal die surface faster.
The technical solution adopted for the present invention to solve the technical problems is: a kind of metal die surface protectant, by weight, this surface protectant has following component formula: aqueous epoxy resins 11-24, mix tung oil 12-26, ethyl acetate 50-65, Sodium isooctanoate 2-4, benzotriazole 0.2-0.4;
Described mixing tung oil is that varnish, rosin and boiled wood oil form 240-260 ℃ of mixed configuration according to mass ratio 2.2:2.3:6.2.
Further, by weight, this surface protectant has following component formula: aqueous epoxy resins 15-22, mixes tung oil 15-23, ethyl acetate 55-60, Sodium isooctanoate 3-3.5, benzotriazole 0.3-0.35.
Further, by weight, this surface protectant has following component formula: aqueous epoxy resins 20, mixes tung oil 19, ethyl acetate 58, Sodium isooctanoate 3.3, benzotriazole 0.33.
Further, described aqueous epoxy resins is hydrophobicity epoxy resin dispersion emulsion and wetting ability amine curing agent according to mass ratio (100-130): (30-33) form.
A preparation method for metal die surface protectant, this preparation method has following steps:
(1) by weight, prepare following component formula: aqueous epoxy resins 11-24, mixes tung oil 12-26, ethyl acetate 50-65, Sodium isooctanoate 2-4, benzotriazole 0.2-0.4;
(2) aqueous epoxy resins and mixing tung oil are added in reactor, under 120-180 ℃ of condition, stir 1.5-2h to evenly, then under agitation condition, carry out room temperature cooling, in process of cooling, add ethyl acetate, Sodium isooctanoate and benzotriazole, stir.
Beneficial effect: the metal die that technical scheme of the present invention provides shows protectant component formula; starting material wide material sources; cost is lower, not fluorine-containing, chlorine element in the very fast and component of rate of drying, safety and environmental protection; do not affect the electroconductibility, insulativity, the weldability that are coated with part; be applicable to the conservation treatment that shows to metal die, the preparation method that this technical scheme provides, technique is comparatively simple; convenient and practical, suitable applying.
