Abstract
The invention relates to the field of chemical powder coating, in particular to a bend-resistance powder coating. The invention aims to provide bend-resistance powder coating which can ensure powder coating films that are more than 60 micrometers thick on workpieces do not crack when the powder coating is sprayed on box bodies, the workpieces or various antitheft doors and the box bodies, the workpieces or the various antitheft doors are punched at 90 to 180 DEG, in order to overcome the low bend resistance drawback of the conventional powder coating. The technical scheme adopted by the invention is implemented as follows: the components of the bend-resistance powder coating include carboxyl resin, triglycidyl isocyanurate (TGIC), BaSO4(filler), delustering agent 803A, curing agent 32-18A and pigment, wherein the acid value of the carboxyl resin is 20 to 40 micrograms of KOH per gram, and the pigment is one or more of titanium white, ferrite yellow, iron oxide red and dry-ground black limestone powder.
Description
Technical field
The present invention relates to the chemical powder paint field, particularly a kind of be used for all kinds of casing, workpiece and all kinds of antitheft doors of making by sheet metal and need spray after the curved powder coating of folding on punching press or crooked 90 °～180 ° of surfaces again.
Background technology
Powder coating is widely used in the application on all kinds of casings, workpiece and all kinds of antitheft doors surface, especially for the application on all kinds of casing, workpiece and all kinds of antitheft doors surfaces of being made by sheet metal.The existing powder coating that is used to spray is the curved powder coating of not folding, no longer carries out the application on casing, workpiece and all kinds of antitheft doors surface of punching press or bending after it only is used to spray.In use, existing powder coating exist when the casing of making by sheet metal, workpiece and all kinds of antitheft door after needing spraying again during 90 °～180 ° of punching presses, powder coating is filmed will the rimose weak point when thickness of workpiece reaches 60um.
Summary of the invention
The objective of the invention is at the curved weak point of the existing above-mentioned not folding of existing powder coating, provide a kind of when the casing of making by sheet metal, workpiece and all kinds of antitheft door after needing spraying again during 90 °～180 ° of punching presses, powder coating is filmed thickness on workpiece still can the curved powder coating of rimose folding when surpassing 60um.
The technical solution adopted in the present invention is finished in the following way: powder coating is bent in a kind of folding, and the component of the curved powder coating of this folding comprises carboxy resin, isocyanuric acid three-glycidyl ester (TGIC), Baso4 (filler), matting agent 803A, solidifying agent 32-18A and pigment.
In the curved powder coating of above-mentioned a kind of folding, the weight ratio of the curved powder coating component of folding is: 40～60 parts of carboxy resins, 3～5 parts of isocyanuric acid three-glycidyl esters (TGIC), 0.5～3 part of 20～40 parts of Baso4 (filler), matting agent 803A, 0.5～3 part of solidifying agent 32-18A, pigment≤10 part.
In the curved powder coating of above-mentioned a kind of folding, it is the carboxy resin of 20～40mgKOH/g that carboxy resin adopts acid value.
In the curved powder coating of above-mentioned a kind of folding, one or more during pigment employing titanium dioxide, iron oxide yellow, iron oxide red, mill are deceived.
The curved powder coating of a kind of folding of the present invention is compared with existing powder coating, has the curved effective outstanding advantage of folding, after existing powder coating is sprayed on the sheet metal workpiece again during 90 °～180 ° of punching presses, powder coating is filmed and will be ftractureed when thickness on workpiece reaches 60um, and the curved powder coating of a kind of folding of the present invention be sprayed on the sheet metal workpiece after again during 90 °～180 ° of punching presses, powder coating is filmed and also can not ftractureed when thickness on workpiece reaches 80um.
