Embodiment Construction
[0019] The present invention will be further described below in conjunction with specific embodiments.
[0020] The production technology of present embodiment active printing paste comprises the steps:
[0021] The first step is to fully mix corn starch and potato starch with sodium hydroxide and chloroacetic acid, extrude with a screw extruder, spray formaldehyde on the material in the second half of the extruder, and finally dry to obtain carboxymethyl starch , the mass ratio of cornstarch, potato starch, sodium hydroxide and chloroacetic acid is 50:50:5:8;
[0022] In the second step, carboxymethyl starch and silicon powder are mixed and added to deionized water, and sodium hydroxide and methanol are added to perform hydrolysis and then dry and purify to obtain a mixture of carboxymethyl starch and nano silicon dioxide. Ratio, 50 parts of carboxymethyl starch, 2.6 parts of silicon powder, 0.1 part of sodium hydroxide, 0.2 parts of methanol;
[0023] Step 3: Add soybean p...
