Problems solved by technology

However, polyethylene film material is a non-degradable material, which takes about 30 years to decompose in the soil, making it difficult for this traditional RC photo paper to degrade
With the development of the times and the increase in sales of photo paper, this kind of non-degradable RC photo paper will cause greater damage to the environment

preparation example Construction

[0034] The preparation method of the degradable and scratch-resistant microporous inkjet photo paper of the present invention specifically comprises the following steps:

[0035] (1) Preparation of degradable RC photo paper base paper

[0036] The base paper base (3) is made of base paper made of all wood pulp or mixed wood pulp, and then double-sided coated with degradable coated layers (2) and (4), the gloss is higher than 50% (60° , GB / 8941-2007).

[0037] (2) Preparation of anti-scratch ink-absorbing layer coating

[0038] Preparation of the dispersion: slowly add 100 parts of nano-alumina, 5-10 parts of nano-cellulose, 0.5-1 part of pH regulator and 0.5-1 part of silane coupling agent to the In deionized water, then increase the stirring speed to 2000-2300 r / min, and spread at high speed for 30-45 minutes to obtain a dispersion with a solid content of 20-25%;

[0039] Aging of the dispersion: put the above-prepared dispersion in a water bath at 60±5°C for more than 12 ...

Embodiment 1

[0046] Preparation of degradable RC photo paper base paper, the paper base (3) is made of base paper base paper made of whole wood pulp or mixed wood pulp, and then double-sided coated with degradable coated layers (2), (4), The gloss is higher than 50% (60°, GB / 8941-2007);

[0047] The degradable coating layers (2), (4) are polylactic acid films;

[0048]The anti-scratch ink-absorbing layer (1) includes the following components in parts by weight: 100 parts of nano-alumina, 10 parts of adhesive, 5 parts of nano-cellulose, 1.0 part of pH regulator, 1.0 part of silane coupling agent, 2 parts of defoamer, 0.2 part of leveling agent, 0.5 part of crosslinking agent. The binder is polyvinyl alcohol; the pH regulator is 10% acetic acid; the defoamer is a mixture of isopropanol and n-butanol in a weight ratio of 3:1; the The leveling agent is a fluorine-modified acrylic copolymer; the crosslinking agent is a mixture of glyoxal and borax in a weight ratio of 2:1;

[0049] Coating ...

Embodiment 2

[0051] This example is the same as Example 1, except that the anti-scratch ink-absorbing layer (1) includes the following components in parts by weight, 10 parts of nanocellulose, to obtain the anti-scratch ink-absorbing layer of Example 2 (1), the evaluation results are shown in the table below.

Abstract

The invention relates to the field of color spray printing media, and provides a preparation method of degradable and anti-scratching microporous ink-jet printing photo paper. The degradable and anti-scratching microporous ink-jet printing photo paper comprises an anti-scratching ink sucking layer, a degradable film spraying layer and a paper base layer, wherein the anti-scratching ink sucking layer contains nano-crystalline cellulose; and the nano-crystalline cellulose forms a three-dimensional network structure in a coating, so that the fastness and the hardness of the coating can be enhanced, and the friction resistance and the anti-scratching performance of the coating are further improved. The microporous ink-jet printing photo paper is safe and environmentally-friendly, high in degrading rate and high in anti-scratching performance, and a printed image is bright in color and high in precision.

Description

technical field [0001] The invention relates to the field of digital printing color jet media, in particular to a degradable and scratch-resistant microporous ink jet printing photo paper and a preparation method thereof. Background technique [0002] Degradable materials are classified according to the external factors of degradation, and can be divided into photodegradable materials, biodegradable materials and environmental degradable materials. Photodegradable materials: can be decomposed and degraded after being irradiated by sunlight; biodegradable materials: due to the action of fungi, bacteria and other natural microorganisms, they are finally decomposed into carbon dioxide and water; environmental degradation materials: It decomposes under the action of natural conditions such as force. [0003] With the development of the "digital" era, color inkjet digital printing has gradually replaced traditional printing, which also stimulates the inkjet printing industry and...
