Abstract

The invention provides an environmental-friendly water-based ink. The environmental-friendly water-based ink is composed of polyester, polyurethane, an antiaging agent, an anti-diffusion agent, a stabilizing agent, deionized water, an infiltrating dispersant, an antifoaming agent, a levelling agent, a drier, an anti-settling agent, an antistatic agent, an anti-ultraviolet agent, a pigment paste, and a thickening agent at a reasonable ratio. The environmental-friendly water-based ink with different hard and soft segments is prepared from the raw materials at different ratio so as to satisfy different bonding strength requirements of different PET products. The environmental-friendly water-based ink is high in strength, wide in application range, and low in cost.

Description

PET water ink

Technical field

The present invention relates to a kind of water color ink of intaglio printing PET film.

Background technology

At present China has plastic printing enterprise 50,000, the people of practitioner 1,700,000, the enterprise of production ink in 2014 3349, about 800,000 tons of ink, wherein 400,000 tons of solvent type ink are produced, the worker at the production line of plastic printing industry is with body The injury of body is exchanged money for cost, the expense of the curing the disease when money earned is old not enough, and our water color ink can allow 1,700,000 members Work is from organic solvent to the injury of body and the discharge of high-risk VOC.

The content of the invention

The invention provides a kind of Environmental-protection water-based ink, is made up of the raw material and processing method of following percentage by weight：

1.150 parts of polyester resin add 300 parts of deionized waters, in vacuum reaction kettle, dissolve under 0.04 MPa 95 °, Ran Houleng But room temperature is arrived, the corresponding deionized water of supplement makes the solution of solid content 33%；

2. aqueous polyurethane emulsion 1-10%, polyester liquid 1-80%, pour into reactor and are sufficiently stirred under 40 ° of constant temperature；

3. age resister 0.1-10%, anti-diffusant 0.1-3%, stabilizer 0.1-1% add stirring in deionized water 5-10% equal It is even；

4. pour into 23,40 ° of constant temperature are sufficiently stirred for 60-120 minutes, form homogeneous emulsion；

5. infiltration dispersant 1-10%, defoamer 0.1-1%, levelling agent 0.1-1%, drier 0.1-1%, anti-settling agent are sequentially added 0.1-1%, antistatic additive 0.1-1%, UV resistant agent 0.1-1% are sufficiently stirred for 60 minutes；

6. pigment paste 1-40% is added, is sufficiently stirred for；

7. it is eventually adding thickener 1-5% to be sufficiently stirred for, adjusts viscosity to 25 seconds, the water color ink of stable homogeneous is obtained.
