Problems solved by technology

[0004] However, the technical problem in the prior art is that the water-based inks used for corrugated box printing on the market generally have unsatisfactory drying performance, and the decomposition and detachment performance of polyacrylic resins widely used in water-based inks is relatively poor, resulting in discarded corrugated boxes. The printing ink on the paper is not easy to recycle and detach, and it is difficult to decompose in nature.
The present invention aims to simplify the preparation process of water-based ink for corrugated boxes with excellent performance, solve the problems of dryness in the production process of corrugated boxes and ink pollution in the waste recycling process, and provide a kind of water-based ink for corrugated boxes in my country. There is an environmentally friendly ink that improves the competitiveness of my country's water-based ink market, reduces the damage to the ecological environment caused by the printing industry, accelerates the pace of "green projects" in the corrugated box packaging and printing industry, and integrates "green environmental protection" and industry organically. combine

Embodiment 1

[0076] Embodiment 1 Preparation of environment-friendly vegetable oil-based polyurethane corrugated cardboard ink

[0077] The preparation process is as follows:

[0078] a. Add 30g of castor oil into a clean beaker with a stirring device, put the beaker into an ultrasonic cleaner, set the temperature at 70°C, and the ultrasonic power at 600W, add 1g of OP-10 to the flask, and stir Mix well; at the same time, take 4g of BMA, 6g of AA and 0.3g of AIBN into a clean empty beaker and use a glass rod to mix and stir to obtain a mixture. Then, when the ultrasonic cleaner started ultrasonic vibration, the mixture was added to the reaction system of castor oil and OP-10. The addition process adopted the method of starvation feeding, and the mixture was added within 2 hours. Obtain the castor oil after polyacrylate monomer modification;

Abstract

The invention relates to the field of corrugated board printing inks and particularly relates to environment-friendly vegetable oil-based polyurethane binder resin, a corrugated board ink and a preparation method of the environment-friendly vegetable oil-based polyurethane binder resin. The polyurethane binder resin is obtained by acting a vegetable oil-based polyurethane prepolymer, a hydrophilic chain extender, a micromolecule chain extender, a neutralizer and water, wherein the vegetable oil-based polyurethane prepolymer is obtained by reacting polyacrylate-modified vegetable oil, low polymer polyatomic alcohol and diisocyanate; and the vegetable oil-based polyurethane water-based ink is obtained by mixing pigments, a defoaming agent, water-based paraffin and water into the vegetable oil-based polyurethane binder resin. The water-based ink has good printability and has good biodegradability by using the vegetable oil to substitute most of organic polymers as synthetic raw materials of the binder resin; and the grain size of the ink is controlled within a micro-nano range, so that the ink is dried on the surface of the corrugated board very well to achieve film-forming and bonding effects.

Description

technical field [0001] The invention belongs to the field of corrugated cardboard printing ink, and relates to an environment-friendly vegetable oil-based polyurethane linking material resin, corrugated cardboard ink and a preparation method. Background technique [0002] my country is a big packaging country in the world, and corrugated boxes occupy an important position in my country's packaging industry. The reason why corrugated packaging paper and its derivative products have developed rapidly is that the development of the corrugated paper industry meets the requirements of my country's environmental protection, sustainable development and conservation-oriented society. It has lightweight, elegant, repeatable and designable And other characteristics can greatly meet the packaging needs of products from all walks of life.
