A kind of transfer method and transfer paper of no-bake strong stretch decorative pattern

Abstract

The present invention relates to the technical field of transfer printing of decorative patterns, in particular to a transfer printing method and transfer paper of non-bake strong tensile decorative patterns. Ink layer, decorative pattern layer and protective varnish layer, a water-based varnish bottom layer is provided between the white ink layer and the hydrosol layer, and the water-based varnish bottom layer is composed of the following components in mass percentage: 25% to 45% of water-based acrylic resin, 10~15% water-based alkyd resin, 5~15% water, 35~45% isopropanol, 0.5~1.0% polymethylsiloxane. The invention effectively improves the delicacy and durability of the decorative pattern on the product, and at the same time improves the efficiency because it is self-drying without baking. In addition, because of its excellent adhesion and stretchability, it can be widely used in various large Surface decoration of curved surface products.

Description

technical field [0001] The invention relates to the technical field of transfer printing of decorative patterns, in particular to a transfer printing method and transfer paper of non-baking strong stretching decorative patterns. Background technique [0002] At present, silk screen printing, pad printing, and hot stamping are mostly used to print decorative patterns on the appearance of products that need to be decorated. However, these methods have their own shortcomings. Specifically, the pattern of silk screen printing is not fine enough, and the dots are too thick; the decorative area of ​​pad printing is too small; hot stamping requires special equipment, and the hot stamping temperature is very high. In addition, the above several technologies can only decorate flat or regular surfaces, but do not have the ability to decorate uneven product surfaces.

AI Technical Summary

Problems solved by technology

However, these methods have disadvantages

Specifically, the pattern of silk screen printing is not fine enough, and the dots are too thick; the decorative area of ​​pad printing is too small; hot stamping requires special equipment, and the temperature of hot stamping is very high

In addition, the above technologies can only decorate flat or regular surfaces, but do not have the ability to decorate uneven product surfaces

[0003] Although there are water transfer printing papers and transfer printing methods that can meet the above requirements in the prior art, these methods require high temperature baking for a period of time to obtain firm adhesion.

In addition, in the field of water transfer printing, the glass transition temperature of most ink materials is above 50°C. The degree of thermal deformation of water transfer printing stickers at room temperature is limited, and it can only be applied on small arc surfaces or concave-convex surfaces, which cannot meet the requirements of large arc surface products. Surface decoration, in this regard, the current practice is to divide the decorative pattern into multiple pieces and construct it separately. This is due to the difficulty of pattern handover and alignment and the butt marks at the junction greatly increase the cost and reduce the aesthetic effect

At the same time, the current water transfer paper cannot be decorated on soft glue because it cannot be synchronized with the stretching and shrinking of the product.
