Description

Injection molding with three-dimensional texture facing and product thereof

Technical Field

The application relates to the technical field of injection molding product facing, in particular to an injection molding piece with a three-dimensional texture facing and a product thereof.

Background

With the increasing demands of consumers on the decoration surfaces of plastic parts such as household appliances, furniture or 3C products, a plurality of plastic products with three-dimensional texture decoration surfaces are present on the market; the three-dimensional texture facing is generally realized by adhering a printed colored pattern layer as a film to a product, or preparing the three-dimensional texture facing and then adhering and combining the three-dimensional texture facing with the surface of the product; the former mode has an unsatisfactory stereoscopic effect, and the latter is a decorative surface obtained by attaching a stereoscopic texture layer, a coloring layer and the like on the surface of one carrier layer, and then combining the carrier layer and the plastic piece integrally to form a product with stereoscopic texture decorative surface effect; and in such a way that the carrier layer is always combined with the product as an integral part and sold integrally as an integral part of the product.

However, the above-mentioned method of preparing three-dimensional texture surface and then combining with injection molding product to form product with three-dimensional texture effect still has certain disadvantages: because the facing contains a carrier layer, the carrier layer is often a sheet of organic material prepared in advance, such as PC, PET, PVC, etc., the carrier layer prepared by the organic material has certain hardness and thickness, and has great difference compared with the thickness and hardness of the injection molding product to which the facing is attached, and the material properties for preparing the facing and the carrier layer are also greatly different; therefore, the deformation of the carrier layer and the injection molding product relative to each other is easy to occur due to the difference of the material properties of the carrier layer and the injection molding product and the like in a short period of time, and particularly, the carrier layer is easier to deform, once the deformation is inevitably separated from the injection molding product and tilted and the like, the injection molding product is carried to generate local deformation, so that the decorative surface display effect cannot be ensured, and the product structure is deformed to influence the use effect.

The existing three-dimensional texture facing is inevitably used as an indispensable component of the facing, and is combined with an injection molding product, so that the integral structure of the carrier layer and the injection molding product is always maintained, and the technical proposal of avoiding the problems caused by the carrier layer from the deformation angle between the carrier layer material and the injection molding product is rarely adopted.

Disclosure of Invention

The utility model provides a to the above-mentioned not enough of prior art, from carrier layer and the angle of moulding plastics and taking place relative deformation easily between the layer, do not contain the carrier layer when providing one kind and still keep moulding plastics product three-dimensional texture bandwagon effect when using, consequently also can not take place carrier layer deformation and influence the injection molding spare that has three-dimensional texture bandwagon effect and the structure of moulding plastics product.

In order to solve the technical problems, the technical scheme adopted in the application is as follows: an injection molding piece with a three-dimensional texture facing comprises an injection molding layer and a first three-dimensional texture layer used for being attached to the injection molding layer, wherein a peelable layer is arranged on the side surface of the first three-dimensional texture layer, which is opposite to the injection molding layer, and the peelable layer is provided with at least one carrier layer.

By adopting the structure, the injection molding piece is formed by arranging the first three-dimensional texture layer and the peelable layer which are attached to the injection molding piece, the peelable layer and the injection molding layer can be peeled off in the using, selling and finished product processes of the actual injection molding piece, the injection molding piece at the moment is the injection molding piece without the carrier layer structure, the first three-dimensional texture layer is still attached to the injection molding piece due to the fact that the carrier layer is not arranged, the three-dimensional texture effect can still be displayed on the external surface of the injection molding piece, and meanwhile, the deformation problem caused by the existence of the carrier layer cannot occur due to the fact that the carrier layer is not arranged in the using process, so that the deformation is not easy to occur between the first three-dimensional texture layer and the injection molding layer on the injection molding piece with the structure, the three-dimensional texture effect is more durable, and the situation that the three-dimensional texture effect is tilted or separated cannot occur.

Further, the peelable layer comprises a carrier layer, a peeling agent layer is arranged between the carrier layer and the first three-dimensional texture layer or the peeling agent is contained in the first three-dimensional texture layer (or the first three-dimensional texture layer and the carrier layer can be peeled off from each other); by adopting the structure, in the actual use process of the injection molding part, the peelable layer can be peeled off from the injection molding layer more flexibly and conveniently, and the three-dimensional texture layer is only adhered to the injection molding layer, so that the injection molding part structure without a carrier layer is formed, and the facing stability and the adhesion firmness of the injection molding part are improved.

Further, the first three-dimensional texture layer is a coated three-dimensional texture layer, and the second three-dimensional texture layer is a UV three-dimensional texture layer; the texture surface of the second three-dimensional texture layer is mutually attached and complemented with the texture surface of the first three-dimensional texture layer; by adopting the structure, namely, the second three-dimensional texture layer is transferred onto the carrier layer through the high-temperature-resistant UV adhesive to be attached to the carrier layer, the second three-dimensional texture layer is coated on the outer surface of the second three-dimensional texture layer through a coating mode, the three-dimensional texture on the second three-dimensional texture layer can be reversely transferred onto the first three-dimensional texture layer through the process, and when the two three-dimensional texture layers are peeled off, the effect of forming the three-dimensional texture on the surface of the injection molding part can be realized; in addition, more importantly, the UV three-dimensional texture layer is adhered to the carrier layer through ultraviolet light curing, the second three-dimensional texture layer is coated and filled in a coating mode, and the first three-dimensional texture layer is formed on the outer surface of the second three-dimensional texture layer, which is equivalent to using texture materials with two different performances, the texture materials with the two different performances cannot be adhered to each other after coating is completed, the first three-dimensional texture layer is tightly combined with the injection molding layer through an adhesive layer, the second three-dimensional texture layer is tightly combined with the carrier layer through ultraviolet light curing, so that the two three-dimensional texture layers can be better stripped from each other in the stripping process, and the three-dimensional texture on the side of the injection molding layer is prevented from being damaged in stripping formation.

Further, a coloring layer or an electroplated layer or a coloring layer and an electroplated layer are arranged between the first three-dimensional texture layer and the injection molding layer; by adopting the structure, the injection molding piece can be attached with the ground color, which is more beneficial to the presentation of three-dimensional textures; and the arrangement of the coloring layer and the electroplated layer can improve the high temperature resistance of the first three-dimensional texture layer, and the high temperature injection molding material cannot influence the injection molding process.
