Embodiment 1

[0016] A polyamide coating agent for trademark tape printing, comprising the following components: methanol, calcium chloride, polycaprolactam, carbon black, alcohol-soluble black dye and antistatic agent;

[0017] The ratio of the ingredients contained is calculated based on the mass ratio of polycaprolactam:

[0018] Polycaprolactam 1

[0019] Methanol 3

[0020] Calcium chloride 2.5

[0021] Carbon black 0.1

[0022] Alcohol Soluble Black Dye 1.0

[0023] Antistatic agent (slurry mass ratio) 0.01%.

Embodiment 2

[0025] A polyamide coating agent for trademark tape printing, comprising the following components: methanol, calcium chloride, polycaprolactam, carbon black, alcohol-soluble black dye and antistatic agent;

[0026] The ratio of the ingredients contained is calculated based on the mass ratio of polycaprolactam:

[0027] Polycaprolactam 1

[0028] Methanol 4

[0029] Calcium chloride 2

[0030] Carbon black 0.4

[0031] Alcohol-soluble black dye 0.6

[0032] Antistatic agent (slurry mass ratio) 0.05%.

Embodiment 3

[0034] A polyamide coating agent for trademark tape printing, comprising the following components: methanol, calcium chloride, polycaprolactam, carbon black, alcohol-soluble black dye and antistatic agent;

[0035] The ratio of the ingredients contained is calculated based on the mass ratio of polycaprolactam:

[0036] Polycaprolactam 1

[0037] Methanol 5

[0038] Calcium chloride 1.5

[0039] Carbon black 1.0

[0040] Alcohol-soluble black dye 0.1

[0041] Antistatic agent (slurry mass ratio) 0.08%.

[0042] In the above three embodiments, the alcohol-soluble black dye adopts oil-soluble nigrosine, and the antistatic agent adopts octadecyl trimethyl ammonium chloride or dodecyl dimethyl benzyl ammonium chloride. With polycaprolactam as the main resin, after using alcohol-soluble black dye, the color of the coating agent is black, and the color of the coating is black after solidification. It is suitable for wet coating, and the bonding strength is high after the coating...

Abstract

The invention discloses a polyamide coating agent for the printing of a label tape. The polyamide coating agent comprises the following components: methanol, calcium chloride, polycaprolactam, carbon black, alcohol-soluble black dye and an antistatic agent. After the alcohol-soluble black dye is used, the coating agent is black and the solidified coating is black; the polyamide coating agent is suitable for the coating formed by the wet method; and after the coating is solidified and dried, the bonding strength of the coating is high, the color fastness is high and the coating meets the printing requirements of common textiles and label tapes.

Description

technical field [0001] The invention relates to a black polyamide coating agent for trademark tape printing. Background technique [0002] Among many trademark materials, polyamide coated tape is favored by customers for its environmentally friendly production process, low cost, and suitable for various printing methods. However, due to its special production process, there are only two colors in the country: original white and whitening, which limit its application range in the field of trademark material printing. Contents of the invention [0003] The problem to be solved by the present invention is to provide a black polyamide coating agent for trademark tape printing, which is simple to make and suitable for wet coating. After the coating is solidified and dried, it has high bonding strength and high color fastness. General textiles and trademarks with printing requirements. [0004] In order to solve the above-mentioned technical problems, the present invention ado...
