Alcohol-soluble high temperature ink formulation

The main purpose and advantages: 170 degree heat-resistant seal, anti-adhesion, odorless.

First, nitrocellulose formula technology:

formula

1/4 second nitrocellulose 30

Ethyl acetate 30

Butyl acetate 30

Butanone 10

Technology

Ethyl acetate, butyl acetate, and butanone were thrown into the dissolution vessel and stirred, and then put into the nitrocellulose. While stirring, the mixture was filtered until completely dissolved.

Second, high-temperature resin formulation process:

Technology

According to the prescribed amount of the formula, the mixed solvent is firstly put into the dissolution vessel and the stirring is started. The resin A and the resin B are slowly thrown into the reaction vessel (in no particular order), and the conditions can be maintained at 60 degrees until only completely dissolved. Dissolve the filter package for later use.

Third, the ink product formula technology:

Nitrocellulose solution 30. 4

High temperature resin liquid 30. 4

Titanium Dioxide 29

Permanent purple 0. 0003

Wax powder 2

Ethanol 4

Ethyl acetate 4

Comprehensive neutralizer 0. 2

Note: The above materials are odorless after being dried separately. Since nitrocellulose is a hydroxyl-terminated compound modified by nitric acid, it has a certain activity and will disproportionate with other substances to generate a new substance with a slight odor.

Fourth, ink technical indicators:

Fineness ≤15

Viscosity 35-50

Heat-resistant seal 170°C

Initial 25-55mm

Shading rate 105

Color approximation

Anti-friction more than 20 times
