Problems solved by technology

However, due to the poor heat resistance of ordinary ink, it is easy to cause the ink to fall off from the Tyvek material. After a long time of processing, the heat-sealing tool will be covered with ink, and it is necessary to stop the machine to clean the ink, which will seriously affect the processing efficiency.

Embodiment 1

[0061] According to the first aspect of the present invention, a heat-resistant water-based ink is provided, which includes the following raw material components in weight percentage: 10% to 20% of modified styrene-acrylic resin liquid, modified styrene-acrylic resin The liquid includes the following raw material components in weight percentage: 30% to 40% of deionized water, 8% to 10% of ammonia water, 20% to 30% of crosslinking agent, 0.02% to 0.05% of defoamer, modified styrene-acrylic acid Resin 30%-35%; heat-resistant acrylic emulsion 40%-60%; high-concentration color paste 20%-40%.

[0062] The heat-resistant water-based ink provided by the invention is applied to Tyvek materials. The heat-resistant water-based ink includes modified styrene-acrylic resin liquid, heat-resistant acrylic emulsion and high-concentration color paste, wherein the modified styrene-acrylic The combination of resin liquid and heat-resistant acrylic emulsion can effectively improve the heat-resist...

Embodiment 2

[0066] On the basis of the foregoing examples, this example further illustrates the components of the heat-resistant sealing water-based ink. Further, the modified styrene-acrylic resin liquid is 10% to 20%, and the heat-resistant acrylic emulsion is 40% to 50%. The high-concentration color paste is 20%-40%; the heat-resistant sealing water-based ink also includes the following raw material components in weight percentage: 1%-3% filler; 1%-3% slip agent; 1%-3% wax powder.

[0067]In this embodiment, the heat-resistant sealing water-based ink also includes fillers, slip agents and wax powders, wherein the addition of fillers hardly affects the viscosity of the entire system, but can improve the heat-resistant adhesion of the system, thereby directly improving the heat-resistant Seal the heat resistance of water-based inks. The smoothness and release characteristics of the slip agent make the surface of the heat-resistant water-based ink smooth, making it difficult for the heat-...

Embodiment 3

[0074] On the basis of the foregoing examples, this example further illustrates the components of the heat-resistant sealing water-based ink. Further, the modified styrene-acrylic resin liquid is 10% to 20%, and the heat-resistant acrylic emulsion is 35% to 50%. 20%-40% of high-concentration color paste, 1%-3% of filler, 1%-3% of slip agent, and 1%-3% of wax powder. The heat-resistant water-based ink also includes the following raw material components in weight percentage: 1%-5% of film-forming auxiliary agent; 1%-3% of coupling agent.

[0075] In this embodiment, the heat-resistant water-based ink also includes a film-forming aid and a coupling agent, and the film-forming aid can help the entire system of the heat-resistant water-based ink to better penetrate and wet the substrate (Tyvek material) Uneven contact surface, when the heat-resistant water-based ink penetrates deeper on the substrate, the adhesion of the heat-resistant water-based ink surface will be better after t...

Abstract

The invention provides heat-sealing-resistant water-based ink and a preparation method thereof. The heat-sealing-resistant water-based ink is prepared from, by weight, 10%-20% of modified styrene-acrylic resin liquid, 40%-60% of a heat-resistant acrylic emulsion and 20%-40% of high-concentration color paste, wherein the modified styrene-acrylic resin liquid is prepared from, by weight, 30%-40% of deionized water, 8%-10% of ammonia water, 20%-30% of a cross-linking agent, 0.02%-0.05% of a defoaming agent and 30%-35% of modified styrene-acrylic resin. According to the heat-sealing-resistant water-based ink disclosed by the invention, the modified styrene-acrylic resin liquid and the heat-resistant acrylic emulsion are combined for use, so the heat resistance of the heat-sealing-resistant water-based ink can be effectively improved, and the heat-sealing-resistant water-based ink can tolerate pressure and temperature in a heat-sealing process and is not easy to fall off from a Tyvek material; and ink is not easy to stick to a heat-sealing cutter, so the problems that the heat-sealing cutter cannot perform sealing work due to ink adhesion, the cutter has to be cleaned after shutdown and production efficiency is influenced are avoided.

Description

technical field [0001] The invention relates to the technical field of printing materials, in particular to a heat-resistant sealing water-based ink and a preparation method of the heat-resistant sealing water-based ink. Background technique [0002] At present, Tyvek is a unique non-woven product launched by DuPont. It is a high-density polyethylene material made of DuPont's patented flash spunbond process. This unique material combines paper, film Combined with the characteristics of weaving, it has waterproof, breathable, light weight, toughness, tear resistance, puncture resistance, high reflectivity, anti-ultraviolet and other properties. Due to these excellent characteristics, whether it is making labels, tags, flags , Banners are widely used in medical packaging and food packaging industries. [0003] However, since it is made of high-density polyethylene material, there is a problem that the surface of the material is highly inert and not easy to print. At present,...
