Accompanying drawing explanation
Fig. 1 is the diagram of circuit of radiator grid preparation method in one embodiment of the invention.
Detailed description of the invention
Below in conjunction with schematic diagram, the preparation method to radiator grid of the present invention is described in more detail, which show the preferred embodiments of the present invention, should be appreciated that those skilled in the art can revise the present invention described here, and still realize advantageous effects of the present invention.Therefore, following description is appreciated that extensively knowing for those skilled in the art, and not as limitation of the present invention.
In order to clear, whole features of practical embodiments are not described.They in the following description, are not described in detail known function and structure, because can make the present invention chaotic due to unnecessary details.Will be understood that in the exploitation of any practical embodiments, a large amount of implementation detail must be made to realize the specific objective of developer, such as, according to regarding system or the restriction about business, change into another embodiment by an embodiment.In addition, will be understood that this developmental work may be complicated and time-consuming, but be only routine work to those skilled in the art.
In the following passage, more specifically the present invention is described by way of example with reference to accompanying drawing.According to the following describes and claims, advantages and features of the invention will be clearer.It should be noted that, accompanying drawing all adopts the form that simplifies very much and all uses non-ratio accurately, only in order to object that is convenient, the aid illustration embodiment of the present invention lucidly.
Core concept of the present invention is, the preparation method of the radiator grid provided, comprising: by plastic pellet by injection mould injection mo(u)lding, forms grid body; Use thermoprinting machine, form one deck blocking film in the thermoprint of part described grid body surface; And prepare a varnish protective cover on the surface at described grid body surface and blocking film, form radiator grid.In the preparation method of radiator grid of the present invention; one deck varnish protective cover is formed on blocking film surface; described varnish protective cover has very strong adhesive ability; described varnish protective cover and described radiator grid are well fit together; varnish protective cover strengthens the weather resisting property of described radiator grid; improve the anti-scratch ability of blocking film, increase the service life.Preparation method's environmental protection of radiator grid of the present invention, cost is low, yields is high.
Concrete, in conjunction with above-mentioned core concept, the diagram of circuit of the preparation method of radiator grid provided by the invention is with reference to shown in figure 1.
Perform step S1, by plastic pellet by injection mould injection mo(u)lding, form grid body.In the present embodiment, adopt the mould of Steel material, and the polishing degree of mould is more than or equal to 2000 orders, the roughness of surface of the described grid body that injection moulding is formed carry out can not destroying in follow-up thermoprint process blocking film and can well and blocking film fuse.Injection molding described plastic pellet is the compound of polycarbonate and polyacrylinitrile, further, the aqueous ingredients of described plastic pellet must ensure lower than 0.5%, and can not contain salt, otherwise blocking film can be caused to bubble, come off damp and hot depositing in experiment, cause poor adhesive ability.
Perform step S2, use thermoprinting machine, need the region thermoprint of thermoprint to form one deck blocking film at the described grid body surface of part.In this enforcement is grinned, how described grid body carries out segmentation thermoprint and in the process of thermoprint, in the process of carrying out thermoprint, the fixed form of adjustment bed die and thermoprint glued membrane guarantees the null displacement of grid body described in thermoprint process, ensures that the fixed pedestal fixture used in thermoprinting machine can guarantee that described grid body can not occur up and down and sway in thermoprint process simultaneously.Further, in described grid body pressing process, fixed pedestal fixture plays the supporting role of described grid body, and not allowing described grid body needs the region of carrying out thermoprint have any movement in pressing process.And, described blocking film is stamped in the process on described grid body by thermoprint glued membrane, the curvature tolerance of adjustment bed die, thermoprint rubber moulding and described grid body, ensure the thermoprint face uniform force of described grid body, guarantee that skew can not be caused because of pressure inequality in grid thermoprint region, make described blocking film be formed in the surface of described grid body uniformly, guarantee at the stronger blocking film of described grid body surface thermoprint one deck adhesive ability.In the present embodiment, radiator grid is made to have imitative electroplating effect.
Perform step S3, prepare a varnish protective cover on the surface at described grid body surface and blocking film, form radiator grid.In the present invention, employing spraying coating process scheme prepares described varnish protective cover on described grid body surface, described varnish protective cover is translucent cover lac varnish, described varnish protective cover comprises one first varnish protective cover and one second varnish protective cover, when described grid body thermoprint face, curved surface is larger, when corner angle change is obvious, grid body surface polishing degree needs to be more than or equal to 2000 orders, because grid body polishing degree is higher, cause grid plastic surface tension very little, this just causes described second varnish protective cover cannot meet adhesive ability requirement at described grid body surface, so first spray the first varnish protective cover described between described second varnish protective cover and described blocking film, described first varnish protective cover increase is stung and is bitten grid body surface, described second varnish protective cover after increase and described blocking film surface conjunction power.In the present embodiment, the thickness of described varnish protective cover should be more than or equal to 18 microns.Varnish protective cover of the present invention, can improve the weather resisting property of radiator grid, increase the service life.
But in the present invention, when the curvature of described grid body is smaller, or time more smooth, grid body surface polishing degree only needs to be more than or equal to the grid surface that 1500 orders can reach performance requriements.Described varnish protective cover comprises the cover warnish of the individual layer of one second varnish protective cover, can not need first to spray one first varnish protective cover, just directly described second varnish protective cover can be sprayed on the surface of described blocking film.
In sum, the preparation method of radiator grid provided by the invention, comprising: by plastic pellet by injection mould injection mo(u)lding, forms grid body; Use thermoprinting machine, form one deck blocking film in the thermoprint of part described grid body surface; And prepare a varnish protective cover on the surface at described grid body surface and blocking film, form radiator grid.In the preparation method of radiator grid of the present invention; one deck varnish protective cover is formed on blocking film surface; described varnish protective cover has very strong adhesive ability; described varnish protective cover and described radiator grid are well fit together; varnish protective cover strengthens the weather resisting property of described radiator grid; improve the anti-scratch ability of blocking film, increase the service life.Preparation method's environmental protection of radiator grid of the present invention, cost is low, yields is high.
Obviously, those skilled in the art can carry out various change and modification to the present invention and not depart from the spirit and scope of the present invention.Like this, if these amendments of the present invention and modification belong within the scope of the claims in the present invention and equivalent technologies thereof, then the present invention is also intended to comprise these change and modification.
