A kind of thermal transfer label surface paper and production method

Abstract

A surface paper with a heat transfer label and a production method thereof are disclosed. The surface paper comprises a layer of original paper, at least a receiving layer is formed on one side or two sides of the original paper layer, and the receiving layer is composed of the following components in parts by weight: 100 parts of white pigment, 5 to 15 parts of adhesive agent, 10 to 20 parts of amorphous mat filling material, and 5 to 15 parts of paint made of hot-melt adhesive; wherein the solid content of the paint is 45% to 70%, the paint viscosity is 400 cps to 1000 cps, and the coating amount of the paint on the receiving layer is 1 g / m2 to 20 g / m2. Preferably, a thermal insulation layer is formed between the receiving layer and the original paper layer. The surface paper with a heat transfer label is obtained by preparing original paper and paint, coating paint on the surface of the original paper, and press-polishing the surface. The surface paper with a heat transfer label has the characteristics of simple preparation method and low cost.

Description

technical field [0001] The invention relates to a thermal transfer label surface paper and a production method, belonging to the technical field of paper production. Background technique [0002] The thermal transfer label is mainly used as a special printing storage medium for two-dimensional code data identification, and will be widely used in financial payment printing, Internet of Things and Internet two-dimensional code identification, and automatic data identification and automatic collection identification of robot production systems. Among them, logistics express and industrial process control are the main application industries of heat transfer label face paper, and they are showing a trend of rapid development. [0003] The working principle of thermal transfer label surface paper printing is: the thermal head controlled by the computer directly contacts the heating point with the constantly changing position with the ribbon, and under the action of heat, the ink o...

Problems solved by technology

[0006] In addition, when the coating of the paper is cold or hot, internal stress is generated due to thermal expansion and contraction. When this stress is concentrated in one place, cracks are easily generated; when the paper is exposed to ultraviolet rays and natural weathering, the paper will also crack. Aging will cause cracks, which will seriously affect the durability, scratch resistance, smear resistance, corrosion resistance and high temperature resistance of the paper

[0007] Chinese patent document CN102800244A discloses an ultra-high temperature wear-resistant thermal transfer label and its preparation method. It is provided with a layer of wear-resistant thermal transfer coating layer on the upper side of the polyimide substrate, and on the lower side of the polyimide substrate. A layer of release paper or release film is set, and the polyimide substrate is connected with the release paper or release film through an adhesive layer; it is mainly through the selection of polyimide film, with its large surface tension , Uniform thickness, to overcome the phenomenon of label paper detachment, displacement and warping when printing at high temperature; the label paper prepared by this preparation method has surface reflection and poor ink acceptance, which makes the barcode printed on the face paper difficult to read problems, as well as poor thermal resistance of facial tissue, easy aging and other deficiencies
