A new water-based environmental protection material used to replace PET dumb film and its preparation method

Abstract

The invention discloses a new water-based environmental-protection material for replacing a PET matt membrane and a preparation method thereof. The new water-based environmental-protection material for replacing the PET matt membrane includes a raw material A, a raw material B and a raw material C, wherein the raw material A comprises the following components: water-based frosted gloss oil, pure water, polyamine wear-resistant microspheres, nano silicon dioxide, an organic extinction agent and a leveling agent; the raw material B includes pure water; the raw material C includes carbodiimide and polyaziridine; the water-based frosted gloss oil includes water-based polyurethane resin, ethanol and a film forming auxiliary agent. The prepared new water-based environmental-protection material for replacing the PET matt membrane has the main components of water-based substances, cannot cause harm to human bodies, and has the advantages of strong adhesion force, low matte degree and good appearance effect. The preparation method is suitable for promotion, and the quality of the product is better.

Description

technical field [0001] The invention belongs to the field of printing ink, and in particular relates to a water-based environment-friendly new material for replacing PET dumb film and a preparation method thereof. Background technique [0002] With the development of the economy and the advancement of science and technology, people have higher and higher requirements for the appearance of products. Traditional glossy materials can no longer satisfy people's aesthetics. It has the characteristics of good flatness and good hand feeling, and is widely used in various packaging manufacturers. However, the polycyclic aromatic hydrocarbons contained in traditional printing inks are volatile solvents, which are harmful to the human body. The volatile organic compounds contained in them not only increase air pollution, but also cause harm to the human body. [0003] Chinese patent CN201510267025.2 discloses a treatment-free matte varnish ink for PET film gravure printing, which con...

Problems solved by technology

The ink of this invention can use ordinary PET light film to achieve partial matte or complete matte through printing, and can also adjust the free control of product matte degree from 2° to 15°, but its matte effect is not good, so it is not suitable for high-end product packaging

[0004] Chinese patent CN104130675A discloses a kind of anti-scratch UV dumb oil for dumb film and preparation method thereof, the scratch-resistant UV dumb oil for dumb film consists of 5-15 parts of epoxy acrylic resin, 20-35 parts Modified acrylic resin, 50-65 parts of acrylic monomer, 10-15 parts of photoinitiator, 5-15 parts of matting agent, 1-5 parts of auxiliary agent, but it adds more Additives will have a great impact on production and technology, that is, the use of downstream enterprises, and the environmental protection performance is not good
