the prior art, the description, the embodiment, and the drawings are brief descriptions. Application of materials. [Prior Art] Background of the Invention An automatic deposition system is an aqueous method for coating a metal. When a small amount of polyatomic metal ions is released from the metal surface, it can be interposed between the W coating and the metal substrate. Response-driven. The aqueous composition must contain a stabilized polymer dispersant. A necessary feature of a coating that can be deposited automatically is that the dispersed material is stabilized by functional groups on the polymer and / or provided by a surfactant, which is a polyvalent ion that enters the aqueous phase. Sensitive. Deposition occurs when sufficient U-valent ions occur on the metal surface, and the multivalent ions interact with these stable functional groups that cause dispersion to cause precipitation. Examples of the auto-deposition composition have been described in European Patent No. 0Π2828, U.S. Patent No. 4,647,48G owned by Bashir M. Ahmed, and U.S. Pat.

In some cases, flushing is not performed. There are still some limitations to the automatic deposition coating method without a washing step on metal parts. The non-rinsing step creates a problem related to the edges of the drainage along the 5 edges, which, when dried, cause the edges of the water to break. These water ruptured edges result in poorer protective coating. Other problems that can arise from trying to mitigate water-collapsed edges, such as variations in dry film thickness (DPT) in different areas of the part's surface. The need for flush-free coating methods is to deposit a sufficient amount of coating that meets the acceptable specifications to reduce the edge of the money, which is highly desirable in the application of immersion auto-deposition coating. [Summary of the Invention] Summary of the Invention According to a preferred aspect of the present invention, there is provided a non-rinsing automatic deposition method for a metal coating in a water-based coating solution containing a solid concentration of a material, a specific water bath temperature and an immersion time. The component is impregnated, where the rate of removal of the impregnated component remains the same or lower than the discharge rate of the flowing liquid portion '. Therefore, the formation of water break edges is minimized and the DFT is kept acceptable based on the removal of the component. Tolerance.

The copolymerizable monomer may be used to form the dimer polymer in an amount of 15 to 30% by weight based on the total monomer weight. In the implementation of emulsion polymerization for the production of latex, common anionic and / or non-ionic surfactants can be used to assist the formation of the latex. Typically anionic surfactants include, e.g., weirates from fatty acids such as lauric acid, stearic acid, and oleic acid; sarcosine lysine derivatives such as methyl glycine; and sodium lauryl sulfate Sulfates; Sulfated natural oils and esters such as Turkey Red 〇}} alkyl sulfate polyethylene; alkali metal alkyl sulfates; epoxidized sulfonates; alkyl polyethylene polyether sulfonates; Propylnaphthalene sulfonate; ', amber salt, such as short-chain fatty alcohol partially esterified tank salts of complex filling salts and epoxidized fatty alcohol scale esters.

If a common surfactant is used based on 100 parts by weight of the total monomer, an amount of 0.01 to 5 parts, preferably 0.1 to 2 parts may be used to form the butadiene polymer. Che Dijia's digas butadiene homopolymer has a colloidal stabilization system characterized by anionic interface activity training. This anionic surfactant includes alkyl 15 546413 sulfonium, description of the invention acid salt and alkane sulfonate (commercially available from Stepan under the trade name POLYSTEP) and alkylated sulfonic acid or salt of biphenyl oxide (E.g., commercially available from Dow Chemical Company under the trade name doWFAX, diundecyldishenyloxyphenyl disulfonate or dihexylbisphenyloxydiacetate). 5 In particular, a preferred butadiene latex as a flexible material is polymerized in the presence of a styrene sulfonic acid, sulfonated styrene, poly (styrene sulfonic acid) or poly (sulfonated styrene) stabilizer. Into latex. Poly (sulfonated styrene) is a preferred stabilizer. This stabilization system is particularly effective for butadiene polymers, which are derived from digas butadiene monomers that are at least 60 weight percent of the total 10 weight of monomers used to form the butadiene polymer. The butadiene polymer latex can be polymerized in the presence of water and styrene sulfonic acid, sulfonated styrene, poly (styrene stone, acid) or poly (sulfonated styrene) stabilizers. The butadiene monomer (and, if a copolymerizable monomer is present) is prepared by an emulsion polymerization technique. The% acid salt may be any salt such as sodium, potassium or quaternary ammonium. Sulfonated sodium styrene is a preferred sulfonated styrene compound. Poly (sulfonated styrene) polymers include poly (sulfonated styrene) homopolymers and poly (sulfonated styrene) copolymers such as maleic anhydride. Poly (sulfonated acetophenone) sodium salts are particularly preferred and are commercially available under the trademark VERSA TL from Natoon Starch. The poly (sulfonated styrene 20) has an average molecular weight of 5 × 104 to 15 × 106, preferably 15 × 105 to 2.5 × 105. As for poly (sulfonated stupid ethylene) or poly (styrene sulfonic acid), it is important to confirm that the emulsion polymerization reaction occurs in the presence of the preformed polymer. In other words, the butadiene monosystem is contacted with pre-formed poly (sulfonated styrene) or poly (styrenesulfonic acid). The stabilizer is present in an amount of 0.1 to 10 parts, preferably 1 to 5 parts, based on 100 parts by weight of the monomers used to form the butadiene polymer. If such a flexible substance is present, it is preferably included in the composition in an amount of 5 to 300 parts by weight based on 100 parts by weight of the novolak shovel of the desired phenol. More preferably, the flexible substance is present in an amount of 25 parts by weight to 100 parts by weight based on 100 parts by weight of the novolak dispersant of the desired phenol. And modified resin dispersants can be hardened by known resin hardening methods to form highly crosslinked thermosets. The hardening mechanism varies depending on the use and type of the phenol resin 10 dispersant. For example, the hardened examples of dispersed soluble phenolic resins are typically achieved by heating the phenol resin dispersant. This dispersed hardening of the novolak can typically be achieved by adding an aldehyde-donating compound. Since the dispersed phenol resin is a novolac, a hardenable material should be used to harden a film formed from a metal-treated composition. It should be noted that the metal-treated composition itself does not include phenol resin hardenables because these hardenables cannot be stored stably in an acidic environment. The hardening of the film can be achieved by the application of a hardenable top coating on the metal-treated film. Typically the metal treatment composition is applied to a metal surface (not automatically in the usual manner, 20 is automatically deposited) and then dried. An auto-deposited top coat containing a hardenable is applied to the metal surface. The hardenable compound contained in the overcoat layer may be an aldehyde-donating compound or an aromatic nitroso compound. An overcoat composition comprising one or both of the above-mentioned hardenables is known and commercially available. 17 546413 (ii) Description of the invention The aldehyde-donating substance may be substantially any type of acid of a phenol resin that reacts with a hydroxy aromatic compound to form a hardened or cross-linked novolak. In the present invention, typical compounds as aldehydes (such as formaldehyde) include formaldehyde and formaldehyde solutions such as formalin; acetaldehyde; propionaldehyde; isobutyraldehyde; 2-ethylhexanoic acid; 2-methyl 5-pentylvaleraldehyde; benzene Formaldehyde; and compounds such as trimeric faldehyde, trinoxane, furan f alcohol, hexamethylenetetramine, anhydrous formaldehyde aniline, ethylene diamine formaldehyde decomposed into formaldehyde; acetals that release formaldehyde when heated; urea and formaldehyde Methylurea derivatives; hydroxycresol compounds; and analogs thereof. It has been found that the primer 10 has been described in U.S. Patent No. 09 / 235,778, as a precoat primer for metal parts. The formaldehyde species generated from the soluble phenolic resin present in the primer appear to be co-hardened by diffusion. Novolac in metal treatment coatings. In addition, the hardening or cross-linking of the novolac can occur by ionic cross-linking and chelation with metal ions generated by the reaction of an acid metal substrate. [5] In the present invention, high molecular weight aldehyde homopolymers and copolymers can be used as a source of formic acid. Potential formic acid sources mentioned herein as formic acid sources will only release formaldehyde when heating is applied as in an adhesive system.

The polyoxymethylene material is also known and can be used with polyoxymethylene ethylene in the presence of an acidic catalyst by a mono- or diethylene glycol and diethylene glycol with 丨 to 8 stone counteratoms. The reaction of alcohol is quickly synthesized. A representative method for preparing these crosslinking agents is described in U.S. Patent No. 2,512,95, which is incorporated herein by reference. Gama · polyoxymethylene scale is generally a better source of potential formazan, and a particularly preferred source of potential formic acid used in the present invention is 2-polyoxymethylene dimethyl ether. 15 Huoxiangshilischokyl compounds can be any aromatic hydrocarbons, such as benzene, naphthalene, onion, biphenyl, and the like, which contain at least two dischinoschokyl groups directly attached to non-adjacent ring carbon atoms. These aromatic nitroso compounds are described in U.S. Pat. Nos. 3,258,388, 4,119,587, and M%. The above-mentioned control agents are particularly useful in the metal-treating compositions of the foregoing invention. ≪ Multi-component compositions in auto-depositable compounds are also expected.

Organic resins include these ethylenically unsaturated monomers derived from, for example, polyvinylidene fluoride, polystyrene, tellurium polyethylene, acrylic acid, acetic acid, and styrene butadiene (see US Patent No. 4,4M, 350, 4,994,521 "427,863, published under 10 and PCT Patent Application No. wo 93/15154). Urethane and polyester resins have also been mentioned as useful. Certain epoxy resins and propylene glycol resins are also said to be useful auto-deposition resins (see U.S. Patent No. 5,500,46 () and PCT Publication Patent No. f 97 97 Cong 63). Blends of these resins can also be used. A preferred auto-depositable resin is described in the water-based pandemic dispersant as a co-application of US Application No. 15 09 / 235,201, and is hereby incorporated by reference. The system relates to the above-mentioned metal treatment composition. A soluble phenolic resin variant is also included in the control agent of the present invention that can be formed into a multi-component composition. The phenol resin precursors and modifiers used to make the dispersed soluble phenol resin are the same as those described for the dispersed novolac. However. The dispersed soluble phenolic resin is prepared by reacting 1 mole of a modifier with 1 to 20 mole of a phenol resin precursor. Dispersed soluble phenolic resin can typically be obtained by mixing a soluble phenolic resin precursor or a soluble phenolic resin precursor with the modifier or without other reagents, additives or catalysis. 20 546413 This compound was obtained by reaction. However, other desired reaction rhenium, additives or catalysts may be used. The polyhydric phenol compound is optionally contained in a relatively small amount in a reactant mixture for a soluble phenol resin. The synthesis of this soluble phenolic resin does not require an acid catalyst. Hydrophilic I * bathable final resins typically have an F / p ratio of at least 1.0. According to the present invention, a hydrophilic soluble phenol resin having an F / p ratio much larger than 10 can be successfully dispersed. For example, it is possible to manufacture an aqueous dispersant having a hydrophilicity ratio of F / P ratio of at least 2> cereal resin, and its F / P ratio can reach 3, which is the theoretical limit of the F / P ratio. According to a particularly preferred embodiment disclosed in the case No. 09 / 235,201, wherein the dispersed phenol resin is a soluble phenolic resin, and the modifier is an ionic suspension drop group X and two reactive substituents γ Naphthalene, the dispersed lipid reaction product containing a mixture of nutrient polymers having a structure that can be expressed by the following chemical formula m:
