Abstract

The invention belongs to the technical field of printing ink, and particularly relates to sand photosensitive printing ink which comprises the following components in percentage by mass: 16-32 wt% of frosting powder, 8-15 wt% of UR-928DE type polyurethane, 3-7 wt% of pigment, 0.5 wt% of antistatic agent, 5-12 wt% of nitrocotton, 0.5-3 wt% of silicone oil, 0.5-3 wt% of auxiliary agent, 5-12 wt% of ethanol and the balance of n-propyl acetate. The ink has a sandy feeling, but is better in abrasion resistance, kneading resistance and antistatic property.

Description

Sand photosensitive ink

Technical Field

The invention relates to the technical field of printing ink, in particular to sand photosensitive printing ink.

Background

When printing old yogurt boxes, some need to use an ink to make the surface feel sandy but have certain flatness. However, the sandy feeling is difficult to realize, and the difficulty is that the sandy raw material is easy to cause surface dusting and generate static electricity, so that the adhesion of the ink is influenced, and the requirement of a client cannot be met.

The present invention therefore provides a new ink formulation to solve the above problems.

Disclosure of Invention

The invention mainly aims to provide a sand-sensitive ink which can make the surface printed by the ink have sand feeling, wear resistance and static electricity prevention.

The invention realizes the purpose through the following technical scheme:

the sand photosensitive ink comprises the following components in percentage by mass: 16-32 wt% of frosting powder, 8-15 wt% of UR-928DE type polyurethane, 3-7 wt% of pigment, 0.5 wt% of antistatic agent, 5-12 wt% of nitrocotton, 0.5-3 wt% of silicone oil, 0.5-3 wt% of auxiliary agent, 5-12 wt% of ethanol and the balance of n-propyl acetate.

Specifically, the auxiliary agent comprises 0.5-3 wt% of wax.

Specifically, the pigment is white carbon black.

Compared with the prior art, the sand photosensitive ink has the beneficial effects that:

the ink has a sandy feeling, but is better in abrasion resistance, kneading resistance and antistatic property.

Detailed Description

The frosting powder is provided by Nanjing Tianshi new material science and technology company, UR-928DE type polyurethane is provided by a huge dragon welfare processing factory in a small store area of Taiyuan, the nitrocotton is 1/16s nitrocotton, the antistatic agent is an HOS 777 type antistatic agent provided by Shanghai lotus Shi industry company, the silicone oil is 3100 silicone oil provided by Guangzhou fluorine marginal silicon science and technology company, and the wax is 540 wax provided by Shanghai Branch company of the Bizhou chemical industry company, wherein the wax can improve the rubbing resistance of the ink.

The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.

Examples 1 to 6:

the sand sensitive inks of examples 1-6 were prepared by mixing according to the formulation of table 1:

table 1: unit: wt.%

	Example 1	Example 2	Example 3	Example 4	Example 5	Example 6
							Frosting powder	16	32	22	20	18	20
Polyurethane	28	25	20	31	35	24
							White carbon black	5	3	7	4	5	6
Nitro-cotton	10	8	10	12	5	8
							Ethanol	9	5	12	7	8	10
Antistatic agent	1	0.5	2	1.2	1.5	1.6
							Wax	2	1	3	1.4	1.7	2.7
Silicone oil	1	0.5	3	2	2.4	1.6

Note: the part with the content less than 100 wt% is made up by n-propyl acetate to make up the rest.

The ink mentioned in CN110724407A was used as a control and applied to a film and tested according to the following method, the test results are shown in Table 2.

The test method comprises the following steps:

① roughness test, testing the film coated with ink with a friction coefficient meter, and recording the value;

② abrasion resistance test, testing the film coated with the ink with an abrasion resistance tester, and observing whether the powder falls off;

③ rub resistance test, rubbing the film coated with ink repeatedly with both hands for 100 times, and observing whether there is fading at last;

④ antistatic test the ink applied to a substrate was tested with an electrostatic tester and the values recorded.

Table 2:

as can be seen from Table 2, the friction coefficient of the inks of examples 1 to 6 was improved by almost 50% as compared with that of the inks of the comparative examples, which proves that the surface was rougher and had a sandy feeling; but the rough surface of the rubber can not cause easy powder falling, fading and charge generation when in friction, and the rubber has better wear resistance, kneading resistance and antistatic property.

The wax in the auxiliary agent is used for improving the lubricity of the ink. If desired, suitable auxiliaries can also be selected according to the desired properties.

What has been described above are merely some embodiments of the present invention. It will be apparent to those skilled in the art that various changes and modifications can be made without departing from the inventive concept thereof, and these changes and modifications can be made without departing from the spirit and scope of the invention.
