Abstract
The invention relates to a method for forming a metal layer on the surface of a resin product. The method is characterized by comprising the following steps: (1) preparing and shaping a primary mold: after preparing and shaping the primary mold, inspecting the primary mold, filling the primary mold, and finally abrading the primary mold with water sand over 200 meshes; (2) turning a silicone mold: turning a final silicone mold; (3) coating a metal powder layer in the silicone mold: putting metal powder over 200 meshes into the mold and shaking evenly; (4) curing and shaping; (5) demolding; (6) mending: using mixed mending materials of the metal powder and unsaturated resin to mend in defective positions on the surface of the product or joint lines; and (7) polishing and coating a protective layer. Through the initial treatment of abrading with the water sand, the smooth finish of the product is greatly improved, and the mold is amended by the mixture of the metal powder and the unsaturated resin, the product has more metallic luster and more natural and realistic effect.
Description
Technical field
The present invention relates to a kind of resin surface and form the metal level method.
Background technology
Because improving constantly and progress of science and technology of living standards of the people, various resin emulation metal productss constantly appear at people's live and work occasion, reduce cost, improve the purpose of decorative effect to reach, the resin surface that for this reason has scientific and technical personnel constantly to develop to make new advances forms the metal level method.
As number of patent application is 200610090584.1 Chinese patent " metallization treating method on a kind of rosin products surface ", and it comprises following method steps: the making of (1) work in-process base substrate; (2) surface treatment of work in-process base substrate; (3) solidifying protection handles.Adopt the inventive method to obtain the rosin products surface and have certain metal-like, antique effect is good, levels are rich, the decorative effect naturalization, cost is lower with plating relatively, and method is environmental protection more, and method also has advantage of wide range of application, as: can be used for practical and ornaments articles for use such as resin craft, resin stringcourse, resin gardens, resin lamp decoration, method is easy to operation.Its defective is that the die surface processing is not enough, causes the rosin products surface metal gloss that molds few, truly true to nature inadequately, and effect is perfect not enough, requires further improvement.
As the patent No. is that 00108115.2 Chinese patent " forms the technology of metal level " on the resin moulded products surface, and it generates material with resin moulded products and fine metal powder and puts into processing vessel.Make this fine metal powder generation material carry out flowability with the surface of this resin moulded products and contact, the result has generated fine metal powder and formed the metal level that is generated by this fine metal powder on the surface of resin moulded products.Can on the surface of resin moulded products, form firm, the high-density metal layer that generates by fine metal powder by this technology.This metal level has conductive capability.Therefore, by adopting electroplating processes, can on this metal level, form metallic film with simple method with precise thickness, certain surface smooth finish and high-peeling strength.In addition, this metal level itself may just have ornamental and so on function and characteristic.Its defective is that the metal level luster effect lacks perfection, and needs compacting, makes moulding and is not suitable for the complicated decorative product in surface.
Summary of the invention
Technical problem to be solved by this invention provides a kind of further improvement, makes product have more metalluster sensation, the simple and practical resin surface formation metal level method of method.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: a kind of resin surface forms the metal level method, it is characterized in that steps in sequence is:
(1) makes moulding kind mould step, behind the making moulding kind mould, check kind of a mould, with filler hole on the die surface or deformation place are filled up, at last, with the above described kind of mould of water sand polishing of 200 orders, the smooth surface that makes kind of mould shines under the light does not have the fine, soft fur pore;
(2) turn over the silica gel mould step; Rout up final silicone mold;
(3) matel coated bisque step in the silica gel mould is placed on the metal powder more than 200 orders and evenly shakes in the mould time, and flowing is bonded on the silica gel mould, pats bonding die surface the excess metal powder is struck down, and with electric dust collector the excess metal powder is drawn recovery;
(4) curing molding step, it is bonding with metal powder to need to pour in the silica gel mould compound of unsaturated polyester into the rock and roll gravity flow at least, also needs to brush one deck compound, and the soup stock of the unsaturated polyester that contains solidifying agent is bought in patch when not dried then; Ladle out soup behind the material, also brush one deck compound at last with flat inwall; And then solidify;
(5) demoulding step;
(6) repair step; Mixing repair material with metal powder and unsaturated polyester on surface defects of products place or spue line is repaired;
(7) polishing and stopping off step.
Described filler adopts the atom ash, or unsaturated polyester and stone flour mixture, and unsaturated polyester and stone flour mass ratio are 1: 0.3～1.9.
Described water sand is recommended to adopt more than 400 orders, and metal powder also is that 400 orders are above, to reach better effect.
Described making moulding kind mould step adopts kind of the mould surface lacquer method of gushing, and checks the planeness of pore, die surface, if it is defective, need repair once more with atom ash or unsaturated polyester and stone flour mixture smooth, until qualified, further to improve the die surface quality.
Metal powder adopts copper bronze or aluminium silver powder in the interior matel coated bisque step of described silica gel mould, and with electric dust collector the excess metal powder is drawn recovery, and to enhance productivity greatly, method is simple and practical, is not easy to destroy the metal powder layer of internal surface.
The compound of unsaturated polyester adopts unsaturated polyester and stone flour mixture in the described curing molding step, and unsaturated polyester and stone flour mass ratio are 1: 0.3～1.9, and necessity with the supporting solidifying agent of unsaturated polyester.Just solidify in the unsaturated polyester general requirement 2 minutes～40 minutes can, solidifying agent is supporting with unsaturated polyester, can select use under the expertise condition in this field.The stone flour granularity is more than 200 orders, preferably more than 400 orders.
In the described curing molding step the compound of unsaturated polyester is poured in the silica gel mould rock and roll gravity flow with metal powder bonding after, also need to brush one deck compound, patch such as glasscloth when not dried are bought the soup stock of the unsaturated polyester that contains solidifying agent then.Can improve the intensity of product so greatly.
Described curing molding step behind the material that ladles out soup, is also brushed one deck compound at last with flat inwall.
Last described making moulding kind mould step includes:
(1) makes clay sculpture goods or resin, plastics, plastering;
(2) on goods, spray gloss varnish;
(3) make preliminary silica gel mould at product surface;
(4) utilize preliminary silica gel mould to produce the kind mould of design requirements.
Compared with prior art, the invention has the advantages that: by preliminary die surface water sand grinding process, improved smooth finish greatly, the repairing of bond powder and unsaturated polyester mixture makes product have more the metalluster sensation, and effect is true to nature more naturally, adopt special equipment to reclaim metal-powder, both improve production efficiency, saved material cost, and processing ease, be not easy to destroy metal powder layer, for the even moulding of massive article provides good condition, adopt cloth such as glass layer to strengthen, improved the intensity of goods, saved the material consumption, reduced cost, and method is simple and practical, implements easily.
