Problems solved by technology

However, almost all water-based inkjet ink products on the domestic market are only suitable for printing on the surface of some polar products, and basically cannot be used on PE products.
The main reason is that there is no water-based inkjet ink product in China that can obtain satisfactory adhesion on the surface of PE materials.

Embodiment 1

[0042] This embodiment provides a high-performance water-based inkjet ink for polyethylene, the composition of which is calculated in parts by mass as follows:

[0043]

[0044] Among them, the propylene resin is a modified chlorinated polypropylene resin, the emulsifier is a mixture of 45% polyoxyethylene sorbitan monolaurate and 55% polyoxyethylene bis-sorbitan monolaurate, silicon dioxide For hydrophilic fumed silica.

[0045] This embodiment also provides a method for preparing a high-performance water-based inkjet ink for polyethylene. The specific preparation steps are as follows:

[0046] Step (1): Place a three-necked flask with an electric stirrer at room temperature, and dissolve the propylene resin in butyl acetate with a solid content of 20%;

[0047] Step (2): Disperse the emulsifier in 30% ionized water, then slowly drop it into the flask in step (1) under constant stirring at a rotating speed of 2600r / min for emulsification, continue stirring for 18h and then stand stil...

Abstract

The invention relates to a surface corrosion preventing and protecting coating and particularly relates to high-performance water-based jet ink for polyethylene and a preparation method of the high-performance water-based jet ink. The high-performance water-based jet ink comprises the following components in parts by mass: 10-30 parts of acrylic resin, 25-45 parts of ethylene glycol, 2-15 parts of butyl acetate, 0.8-4.5 parts of an emulsifying agent, 2-4 parts of silicon dioxide, 5-10 parts of a bactericide and 8-15 parts of direct black, wherein acrylic resin is modified chlorinated polypropylene resin, the emulsifying agent is a mixture of 45-75% polyoxyethylene sorbitan monolaurate and 25-55% polyoxyethylene bisorbitan monolaurate, and silicon dioxide is hydrophilic gas-phase silicon dioxide. The high-performance water-based jet ink is relatively long in service life and high in use safety; multiple performance tests prove that the high-performance water-based jet ink has excellent adhesive force, wear resistance, weather resistance as well as favorable salt mist resistance, damp and heat resistance and flexibility.

Description

Technical field [0001] The invention belongs to the technical field of coatings, and relates to a surface anticorrosive protective coating, in particular to a high-performance water-based inkjet ink for polyethylene and a preparation method thereof. Background technique [0002] As modern society pays more and more attention to the health and safety of food, medicine, cosmetics and other products, more and more countries have established relevant laws and regulations to clearly stipulate the label, bottle cap, bottle tail and other packaging materials of food, medicine, cosmetics and other products. Product information such as production date, batch number, and shelf life must be printed in a timely manner to protect the health and safety of consumers. Therefore, coding inks have been widely used. However, because the surface energy of the PE material is too low, it is extremely difficult to bond, even if the solvent-based inkjet ink product is barely printed, the ink layer has p...
