Abstract

The utility model relates to a colorful printing PU foamed product, in particular to a PU foamed product that is used for printing fine picture and text on the irregular surface, which comprises a transferring printing film that consists of a plastic base material layer, a composite rubber layer, a stripped layer and a printing layer, wherein, the transferring printing film can be deformed in advance according to the shape of the PU foamed product, and then is arranged inside a PU foaming mould, and then PU foaming material components are filled into the mould, so that the printing layer is transferred to the surface of the PU foamed product through the power and the activity during the forming reaction process, and finally the base material layer, the composite rubber layer and the stripped layer are removed after the formation. The PU foamed product has the advantages that the PU foamed product with fine picture and text that are color-printed can be obtained, and the picture and the text are continuous, and the local printing surface or all surfaces of the product can be printed with continuous and fine colorful or mono-color picture and text at one time. Moreover, the PU foamed produce is environment friendly and saves energy. The production process is greatly reduced, and the production cost is reduced, and the product quality and the production efficiency are improved.

Description

Colour printing PU foaming product

Affiliated technical field

The utility model relates to a kind of colour printing PU foaming product, refers in particular to the PU foaming product at the meticulous picture and text of irregularly shaped object surface printing.

Background technology

The surperficial diagram text manufacture of traditional PU foaming product all is to adopt the mode of spraying paint, and both divides the surface that several times color is sprayed on the PU foaming product by a hollow out mould handle, forms certain pattern decoration effect.The new technology that has recently adopts the mode of pasting in the mould, specifically is in advance the label of one or several independent picture and text that print to be placed on the inwall in the PU foaming mould, utilizes the PU foamed forming process that text and graph label is cohered in product external surfaces.

Above-mentioned first kind of technology can only simple color of spray and picture and text, and pollute big, can't environmental protection.The second way only is adapted at the picture and text labeling of local surfaces, and because label is inconsistent with the material physical property of material and PU foaming itself, makes product surface that foreign body sensation be arranged, and picture and text also can't show the effect of an integral body continuously.

The PU foaming product with characteristic divide hard, soft, high resilience, medium elasticity, from skinning, a lot of products such as slow resilience divide regular shape with shape, as square body, cylinder, cone and irregularly shaped as spheroid, the convex-concave surface product, public young personage, cartoon figure etc.

Adopting above-mentioned traditional technology is to print continuous meticulous colored picture and text, especially may not realize at irregular product surface on these PU foaming products.

Summary of the invention

The utility model just provides a kind of new structural design, structurally innovates, and finishes the irregular and meticulous picture and text printing of regular surfaces of PU foaming product.

The technical scheme that its technical problem that solves the utility model adopts is:

(1), compound transfer printing film is set, altogether three-decker, the base material of plastics, nonpolar plastic foil, printed layers, also can be directly on nonpolar plastic foil direct printing figure message (two-layer structure), substrate layer is by common plastic sheet such as PP, PE, PS, PVC, PET, PVA, PA, PU etc., nonpolar layer is selected silicone oil, the wax class, nonpolar film PE, PS, EVA, printed layers is by common offset printing, gravure, flexo, modes such as silk-screen are finished, the purpose of above-mentioned design is: the picture and text of printing can be in the PU foaming process, and by A, power and activity that the reaction of two components of B produces are directly transferred to printed layers on the PU goods, the characteristics of this nonpolar film exactly can when printing by printing machine colored picture and text are counter be imprinted on above,, can guarantee the adhesion little again to printed layers, be convenient to next step trans-printing.If use remover can reach this effect certainly.Sometimes in order to save cost, also can save the plastic basis material layer, directly use nonpolar film itself, directly print thereon.

(2), the plastic deformation structure of compound transfer film is set, if the PU foaming product is plane, cylinder, the conical surface, perhaps other regular shapes that just can reach by the plane simple bending can not carry out this step.For those spheres, male and fomale(M﹠F), the product of special-shaped surfaces such as public son, toy, need in advance the transferring print film in the first step to be carried out plastic deformation in this step, in whole technology, be called and give distortion, the PU foaming product of definite shape, its whole three-dimensional surface can be divided into a or some part, if it is a, then whole transferring print film just carries out in advance plastic deformation according to this a surface configuration, and it is consistent or close with the appearance of PU foaming product that it is deformed into.If be divided into more than two parts or two parts, then accordingly those transferring print films and that a product surface of distributing are carried out corresponding plastic deformation respectively, the energy complete combination went out the three-dimensional surface of product after some parts that assurance is distributed were made up.The hot plastic uptake of the general employing of plastic deformation, cold pressing to mould and wait all plastic deformations, in this step, require to note that a certain position of each details of picture and text and the PU goods that will print moulding is corresponding one by one or approximate corresponding, generally speaking, carry out plastic deformation and will use auxiliary mould, and auxiliary making of touching tool is according to being to be deformed into transferring print film with the surperficial consistent of PU foaming final products or to be similar by this mould.

(3), foaming transfer printing structure is set, transferring print film after the above-mentioned distortion is placed on accordingly in the mould of PU foaming use, make printed layers inwardly, the plastic basis material layer is towards die face, with mixed A, the PU foamed material of two components of B directly is driven in the foaming mould, A, and two components of B are directly carried out haptoreaction on printed layers, while A, foamable reaction is qualitative gradually in mould for two components of B, behind the certain hour, and depanning, throw off the plastic layer and the nonpolar layer on surface, picture and text just are formed on the surface of PU foaming product.The PU foaming product that requires for unlike material, as hard, soft, high resilience, medium elasticity, from skinning, this novelly all is suitable for slow resilience etc.

By technique scheme, obtain colour printing PU foaming product of the present utility model, the spy is characterised in that:

(1) can form meticulous colored picture and text on the surface, but also be continuous, no matter be all surface of local print surface and product can both one-step print on continuous, meticulous colour or monochrome facsimile.

(2) for the product of different shape, no matter be rule of surface and irregular PU foaming product, the utility model can both obtain all surfaces PU foaming product of colored printing simply.

(3) because compound transfer film adopts environmental printing, so the printing of final product surface is environmental protection.

(4) the PU foaming product that requires for unlike material, as hard, soft, high resilience, medium elasticity, from skinning, products such as slow resilience, the utility model can both obtain satisfied goods.

(5) because the power of the transfer reaction of using is not common hot transfer printing and pressure transfer printing, but utilize be two component reaction of A, B the time self activity, so just realized energy-conservation.

(6) because formed product process and trans-printing process are to finish synchronously, so just save production process greatly, reduced production cost, improved product quality and production efficiency.
