Embodiment 1

[0020] See figure 1 The thermal sublimation transfer paper of the present invention comprises a base paper 1, a sizing layer 2 and a coating layer 3 formed of soft polymer glue that are successively covered on one side of the base paper 1 along the thickness direction of the base paper 1, through which the sizing layer can Reduce the penetration of ink in the paint layer into the base paper. When sizing, the sizing material can penetrate into all base paper 1 coated with the sizing material.

[0021] The sizing material of the sizing layer 2 is prepared by sizing agent, filling material and auxiliary agent, wherein the sizing agent, filling material and auxiliary agent are respectively 30-80 parts, 10-30 parts, 1 -10 copies. The sizing agent contains any one or more of polyvinyl alcohol, alkyl ketene dimer, alkenyl succinic anhydride, carboxymethyl cellulose, styrene-maleic anhydride copolymer, and modified oxidized starch. The proportion of the composition, the sizing agen...

Embodiment 2

[0027] This embodiment is the method for producing the sublimation transfer paper in the first embodiment.

[0028] The method is an in-machine production from base paper forming to surface sizing to in-machine coating for one-time forming, specifically including the following steps:

[0029] Step 1: Copy base paper 1.

[0030] The pulp used to make base paper 1 is formed and dried on a high-speed paper machine to obtain unsized base paper 1 . Wherein, the composition and preparation of the base paper 1 slurry can be the composition and preparation of the base paper 1 slurry commonly used in the field, so it will not be repeated here.

[0031] Step 2: In the high-speed paper machine, the sizing material is embedded in the inner surface layer of the base paper 1 obtained in the step 1 to form a sizing layer 2 by means of roller sizing, wherein the sizing amount is 0.5-2g / m 2 .

[0032] Before sizing, it is necessary to configure the sizing material for configuring the sizing...

Embodiment 3

[0041] This embodiment is to compare the drying speed and transfer rate of the thermal sublimation transfer paper in Example 1 with the drying speed and transfer rate of the thermal sublimation transfer paper in the prior art. Two cases: Case 1, the sublimation transfer paper coated outside the machine on the market; Case 2, the sublimation transfer paper coated inside the machine sold on the market.

[0042] The following is a further description of the two important technical indicators of the drying speed and transfer rate of the sublimation transfer paper.

[0043] (1) Drying speed

[0044] The printing drying speed of sublimation transfer paper is usually combined with the actual application situation, and the evaluation method of printing drying speed based on the principle of bonding and sticking is developed. That is to choose a color block with a darker color (the darker color pattern has a large amount of printing ink, and the drying speed is usually slower after prin...

Abstract

The invention provides thermal dye sublimation transfer paper suitable for on-line high-speed production. The thermal dye sublimation transfer paper comprises body paper, a gluing layer and a coatinglayer, and the gluing layer and the coating layer coat the body paper in sequence according to an on-line processing technology; coating in the coating layer is at least prepared from a water absorbing material, an ink absorbing material and resin. The thermal dye sublimation transfer paper is characterized in that the water absorbing material is a composition containing one or more of sodium polyacrylate resin, aluminium silicate, calcined kaolin and silicon dioxide according to any proportion, and the ink absorbing material is a composition containing one or more of sodium carboxymethyl cellulose, polyacrylamide, sodium alginate, oxidized starch and natural polymer glue. The thermal dye sublimation transfer paper produced by means of the technology solves the problems in the prior art that thermal dye sublimation transfer paper prepared by means of an on-line coating method is low in ink absorbing amount, low in transfer rate, high in ink permeability and low in printing precision.

Description

technical field [0001] The invention relates to thermal sublimation transfer paper, in particular to a thermal sublimation transfer paper suitable for high-speed production in a machine. Background technique [0002] The traditional printing technology is limited by the plate making, the personalized production is difficult, the structure of the pattern is simple and the accuracy is poor, and the disadvantages of high ink usage and pollution have been difficult to meet the needs of the market. However, with the advancement of technology, sublimation transfer technology can be widely used in the processing of textiles, porcelain cups, porcelain plates, porcelain plates, metals and other materials, coupled with the flexible production methods of digital printing machines, single size, traditional It can be produced according to individual requirements, greatly changing the limitations of traditional printing industry production, and its advantages of convenient production, low...
