Abstract
The utility model discloses a kind of cold-reduced sheet, comprise as base material cold-rolled steel flaggy (1), be formed at cold-rolled steel flaggy (1) surface tin metal layer (2), be formed at tin metal layer (2) surface chromium metal level (3), be formed at chromium metal level (3) surface dimethyl silicone polymer composite coating (4).Tin metal layer (2) has makes steel plate have antirust, corrosion-resistant effect, chromium metal level (3) has the effect making steel plate light attractive in appearance, dimethyl silicone polymer composite coating (4) is a kind of anticorrosive coat, effectively prevents surface of steel plate from producing fingerprint, makes sheet material have aesthetical properties further.Thus the utility model has and not easily gets rusty, by the feature of burn into surface aesthetic.
Description
Technical field
The utility model relates to a kind of cold-reduced sheet.
Background technology
Cold-reduced sheet, centered by car body purposes, has a wide range of applications field.But common cold-reduced sheet existence is easily got rusty, by the inaesthetic shortcoming in burn into surface.
Utility model content
The utility model solves the existence of common cold-reduced sheet and easily gets rusty, by the inaesthetic technical problem in burn into surface.For this reason, the utility model provides a kind of cold-reduced sheet, has and not easily gets rusty, by the feature of burn into surface aesthetic.
To achieve these goals, the utility model adopts following technical scheme:
A kind of cold-reduced sheet, comprise as base material cold-rolled steel flaggy, be formed at cold-rolled steel flaggy surface tin metal layer, be formed at the chromium metal level on tin metal layer surface, be formed at the dimethyl silicone polymer composite coating of chromium layer on surface of metal.
The beneficial effects of the utility model: tin metal layer has makes that steel plate is antirust, corrosion-resistant effect, chromium metal level has the effect making steel plate light attractive in appearance, dimethyl silicone polymer composite coating is a kind of anticorrosive coat, effectively prevents surface of steel plate from producing fingerprint, makes sheet material have aesthetical properties further.Thus the utility model has the advantages that not easily get rusty, be not subject to burn into surface aesthetic.
Accompanying drawing explanation
Fig. 1 is cross-sectional view of the present utility model.
In figure, 1. cold-rolled steel flaggy, 2. tin metal layer, 3. chromium metal level, 4. dimethyl silicone polymer composite coating.
Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
A kind of cold-reduced sheet as shown in Figure 1, comprise as base material cold-rolled steel flaggy 1, be formed at cold-rolled steel flaggy 1 surface tin metal layer 2, be formed at the chromium metal level 3 on tin metal layer 2 surface, be formed at the dimethyl silicone polymer composite coating 4 on chromium metal level 3 surface.
The manufacture method of the present embodiment is: after cold-rolled steel flaggy 1 being carried out acid washing phosphorization, washing process, put into tin plating electrolyte.The component of tin plating electrolyte is the sub-tin 10g/L of hydroxy methane sulfonic acid; Ethane sulfonic acid 100g/L; Ethylene thiourea 50 g/L; Formaldehyde 50 g/L; Polymine polyethylene glycol 1 g/L; Cresol sulfonic acid 1 g/L; Hydroxy methane sulfonate 50 g/L; Polyoxyethylene aliphatic alcohol ether 2 g/L; All the other are distilled water.Control electric current is 3A/dm2, after plating 30min, forms tin metal layer 2, has electroplated after washing.
Immersed by sheet material in chromium plating liquid, the formula that chromium plating is nullified adopts chromic anhybride 200 g/L, trivalent chromium 3 g/L, sulfate radical 3 g/L, chromium plating time 10min, and form chromium metal level 3, thickness is about 20um;
Dimethyl silicone polymer compound masking liquid is sprayed at plate surface, after cold curing, forms dimethyl silicone polymer composite coating 4.The compound method of dimethyl silicone polymer compound masking liquid is: comprise dimethyl silicone polymer 29 parts, polytetrafluoroethylene (PTFE) 9 parts, paraffin oil 1 part, titanium oxide 3 parts, auxiliary agent 1 part, ethanol 60 parts by weight ratio.The amine value of polyamide is 210, molecular weight 1500.Auxiliary agent is made up of fluorocarbon surfactant, organo-silicon coupling agent and silicone oil.By polytetrafluoroethylene (PTFE), oxide and paraffin oil mixed grinding, then add auxiliary agent and ground solid material ball milling; Dimethyl silicone polymer is dissolved in ethanol; The solid material that ball milling is good mixes with solution; Finally add polyamide, obtain dimethyl silicone polymer compound masking liquid.
By reference to the accompanying drawings detailed description of the invention of the present utility model is described although above-mentioned; but the restriction not to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various amendment or distortion that creative work can make still within protection domain of the present utility model.
