Problems solved by technology

[0003] The above-mentioned first process can only spray simple colors and graphics, and it pollutes a lot and cannot be environmentally friendly.
The second method is only suitable for graphic labels on local surfaces, and because the physical properties of the label material and PU foam itself are inconsistent, the surface of the product has a foreign body feeling, and the graphics and texts cannot continuously show an overall effect.
It is impossible to print continuous fine color graphics on PU foam products with traditional technology, especially on the surface of irregular products.

Embodiment 1

[0034] Example 1 High-elastic PU foam color printing ball

[0035] figure 1 The PS plastic base material 1 is selected, the non-polar PP material 2 is selected as the peeling layer, and the printing layer 3 is surface lithographically printed by offset printing to obtain fine printed graphics. choose image 3 The shown ball 4 is the target product, the middle circumference line of the ball is used as the parting line 5, and the printing transfer mold composed of 1, 2, and 3 is passed through Figure 5 The plastic deformation mold 7 in carries out plastic deformation, obtains Figure 6 As shown in the pre-deformed post-transfer printing film 9, as Figure 10 As shown, 9 is placed in the PU foaming mold 10, and the printing layer is placed inward, as Figure 9 As shown, the mixed material 13 of A and B mixed with high resilience PU foam is injected into the foaming mold 10 through the mixing injection port 12, as Figure 10 As shown, A and B materials are mixed and placed i...

Embodiment 2

[0036] Example 2 PU foam color printing ball on leather surface

[0037] figure 1 The PVC plastic base material 1 is selected, the non-polar wax 2 is selected as the peeling layer, and the surface printing layer 3 is lithographically printed by gravure printing to obtain fine printed graphics. choose image 3 The shown ball 4 is the target product, the middle circumference line of the ball is used as the parting line 5, and the printing transfer mold composed of 1, 2, and 3 is passed through Figure 5 The plastic deformation mold 7 in carries out plastic deformation, obtains Figure 6 As shown in the pre-deformed post-transfer printing film 9, as Figure 10 As shown, 9 is placed in the PU foaming mold 10, and the printing layer is placed inward, as Figure 9 As shown, the mixed material 13 of A and B foamed from the crust PU is injected into the foaming mold 10 through the mixing injection port 12, as Figure 10 As shown, A and B materials are mixed and placed in 10.

Abstract

The invention introduces a method for printing fine pictures and texts on the surfaces of PU foam products, particularly printing fine continuous pictures and texts on the surfaces of irregular products. Through a special printing proposal with transfer in molds, all the PU foam products can achieve the effects of color pictures and texts on all surfaces, no matter whether the PU foam products are soft or hard.

Description

Technical field [0001] The invention relates to a color-printed PU foamed product, in particular to a PU foamed product with fine graphics printed on an irregular surface. Background technique [0002] The surface graphics of traditional PU foam products are made by spraying paint, that is, through a hollow mold, the color is sprayed on the surface of PU foam products several times to form a certain graphic decoration effect. Recently, some new technology adopts the method of in-mold sticking. Specifically, one or several printed labels with independent graphics and texts are placed on the inner wall of the PU foam mold in advance, and the graphics and text labels are bonded by the PU foam molding process. on the outer surface of the product. [0003] The above-mentioned first process can only spray simple colors and graphics, and it pollutes a lot and cannot be environmentally friendly. The second method is only suitable for graphic labels on local surfaces, and because t...
