The present invention relates to the hot-spraying technique of the compound transition zone of a kind of non-metal material surface band.The technology that the present invention proposes is by a kind of compound transition zone of being made up of binding agent and hard particles being set between nonmetallic materials and sprayed coating, carrying out thermal spraying again on this compound transition zone.The weight of compound transition zone is 200-500g/m
2, adhesive thickness is 0.05-0.20mm, grain graininess is 40 orders-280 orders.This technology is drawn materials conveniently, field construction simple to operate, with low cost, suitable, and it is mainly used in the decoration and the making of building, sculpture, historical relic, handicraft, advertisement, signboard, mural painting, also can be used to make the moulding of mould and thin-walled parts.
Description
The present invention relates to the hot-spraying technique of the compound transition zone of a kind of non-metal material surface band, belong to technical field of surface.
In nonmetallic materials, when directly carrying out thermal spraying as surfaces such as cement, gypsum, glass, pottery, plastics, timber, sun-dried mud bricks, because adhesion is poor between sprayed coating and the matrix nonmetallic materials, sprayed coating is easy to peel off, even when spraying, come off with regard to peeling, and some nonmetallic materials poor heat resistance, produce carbonization, dehydration efflorescence, distortion in when spraying and phenomenon such as dissolve, have influence on practical application fully.
In order to overcome above-mentioned shortcoming, the present invention proposes the hot-spraying technique of the compound transition zone of a kind of non-metal material surface band.
The present invention realizes like this, be coated with the last layer binding agent at clean and dry non-metal material surface earlier, dense layer overlay granularity is 40 orders～280 purpose hard particles on this layer binder again, the thickness of adhesive layer is advisable can cling this layer particle, be generally 0.05～0.20mm, after the adhesive cures drying, brush away the not firm particle of bonding with hard brush, on the compound excessive layer of this layer, carry out thermal spraying then.Can also be blended in particle and be coated in non-metal material surface in the binding agent, after solidifying drying, become compound transition zone.Or both combinations, repave and spill one deck particle in the adhesive surface that is mixed with particle of coating, after solidifying drying, become compound transition zone.Compound excessive layer can only apply one deck, also can repeat to apply multilayer, becomes the compound transition zone of thickening.The thickness of compound transition zone is 200～500g/m

The used binding agent of compound transition zone can be organic synthetic resin and their modified resin such as epoxy resin, polyurethane resin, phenolic resins, organic siliconresin; Can be natural gums such as hide glue, gelatine, natural gum, also can be waterglass (sodium silicate solution), and inorganic binders such as cement mortar should add corresponding curing agent during use.
The used hard particles of compound transition zone can be that granularity is 40 orders～280 purpose glass sands, quartz sand, emergy, natural sand, various metal fine and various refractory material powder.
The present invention uses the bottom of above-mentioned binding agent as compound transition zone, this layer binder with the hard particles secure bond on its top layer at non-metal material surface.The present invention uses the top layer of the hard particles of certain particle size as compound transition zone again, make the surface of compound transition zone become the even roughness face of certain particle size, strengthened inlaying between compound transition zone and the thermally sprayed coating, anchor effect, improved the adhesion between nonmetallic materials matrix and the thermally sprayed coating greatly, improved thermal spraying efficient, overcome when non-metal material surface directly carries out thermal spraying sprayed coating and be easy to the shortcoming of peeling off, being difficult to back processing such as polishing.
Poor thermal conductivity, the good heat resistance of glass sand, quartz sand, emergy, natural sand and various refractory material powder that the present invention uses, make the compound transition zone of this layer that is coated in non-metal material surface play thermal insulation layer, this has just improved the hear resistance of nonmetallic materials when thermal spraying greatly, makes to use technology of the present invention not to be subjected to the stable on heating restriction of nonmetallic materials itself substantially when non-metal material surface carries out thermal spraying.Generally can all can use technology of the present invention to carry out the surface heat spraying with the nonmetallic materials of binding agent bonds well.
Use technology of the present invention when non-metal material surface sprays various metal, can adopt the electric arc spraying and the spraying of oxygen one acetylene torch of metal wire material or bar; To spray glass etc. at non-metal material surface and then generally adopt the spraying of oxygen one acetylene torch powder when nonmetal.
When non-metal material surface thermal spraying glass, should adopt the compound transition zone of thickening, so that non-metal material surface has enough hear resistances.
Utilize technology of the present invention, as long as compound transition zone on the sculpture prototype surface applied that concrete, earth, gypsum etc. are made, selected metal is gone up in spraying again, also can polish processing when needing, can cause the appearance of various metal carvings such as red copper, bronze, brass, stainless steel, aluminium and aluminium alloy, lead, zinc, tin and alloy thereof at the metal spraying laminar surface.Then can produce the appearance of white marble sculpture as spraying glass on compound transition zone.This technology is drawn materials conveniently, field construction simple to operate, with low cost, suitable.
Utilize technology of the present invention, can carry out incrustation, make the building surface of nonmetallic materials such as concrete, masonry, timber produce the appearance of various metals or white marble building.Simultaneously building itself is also played protective action.
Utilize technology of the present invention, can also make large-scale mural painting, art is made lamp box, advertisement, signboard, imitated historical relic etc.
Technology of the present invention can also be applied to make mould and carry out the complex thin-wall component moulding on the moulded pottery not yet put in a kiln to bake surface.
