To achieve these goals, technical scheme of the present invention is as follows.
A kind of stereoscopic printing slurry, according to the mass fraction, composed of the following components: polyethyleneglycol diacrylate: 10~40 parts; PMA: 100~500 parts; Trimethylolpropane: 10~50 parts; Polysiloxanes: 5~30 parts; N-isobutoxy Methacrylamide: 15~80 parts; Vinyl acetate: 5~50 parts; Calgon: 4~60 parts; Sodium alginate: 150~300 parts; Soda ash: 5~30 parts; Starch: 5~10 parts; Chain extender: 3~10 parts; Catalyst: 0.2~0.6 part.
Further, described chain extender is one or several in ethylenediamine, BDO, ethylene glycol.
Further, described catalyst is a kind of in dibutyl tin laurate or acetic acid dibutyl tin.
Stereoscopic printing slurry based on above-mentioned formula, its preparation process is as follows:
(1) by above-mentioned raw materials quality proportioning, polyethyleneglycol diacrylate, PMA, trimethylolpropane, polysiloxanes, chain extender, catalyst are added in reactor, stir and heat up, 50~90 ℃ of reactions 6~10 hours, make performed polymer;
(2) above-mentioned performed polymer is put in emulsifying kettle, cools to 20~50 ℃, add above-mentioned raw materials quality proportioning, after vinyl acetate stirs, rapid stirring, adds 500~2000 parts of deionized waters, carries out emulsification, makes emulsion;
(3) while stirring toward the N-isobutoxy Methacrylamide, soda ash and the starch that add above-mentioned raw materials quality proportioning in emulsifying kettle, make pre-polymerization emulsion;
(4) above-mentioned pre-polymerization emulsion is joined in resin polymerization still, and add calgon, the sodium alginate of above-mentioned raw materials quality proportioning, stirring and dissolving is even, makes the aqueous solution;
(5) resin polymerization still is stirred and is warmed up to 65~90 ℃, carry out chemical reaction 4~10 hours;
(6) then cool to 20~40 ℃, stir 30~60 minutes, then filter blowing, obtain this product.
The above-mentioned stereoscopic printing slurry preparing, for plain net or ROTARY SCREAM PRINTING, stamp post-drying temperature is 60~80 ℃, and drying time is 90~120 minutes, and prepared decalcomania has good convex-concave sense.
This beneficial effect of the invention is: utilize above-mentioned formula and process to prepare the stereoscopic printing slurry of gained, in PLATE SCREAM PRINTING or ROTARY SCREAM PRINTING, after being printed on and shaping by baking on cloth, the pattern obtaining has convex-concave sense, and color clear contrasts strongly.
The specific embodiment
Below in conjunction with embodiment, the specific embodiment of the present invention is described, to better understand the present invention.
embodiment 1
The present embodiment neutral body printing paste, composed of the following components: 10 kilograms of polyethyleneglycol diacrylates, PMA double centner, 10 kilograms of trimethylolpropanes, 5 kilograms of polysiloxanes, 15 kilograms of N-isobutoxy Methacrylamides, 5 kilograms of vinyl acetates, 4 kilograms of calgons, 150 kilograms of sodium alginates, 5 kilograms of soda ash, 5 kilograms of starch, 3 kilograms of chain extenders, 0.2 kilogram of catalyst, described chain extender is ethylenediamine, and described catalyst is dibutyl tin laurate.
The measured step of preparing of above-mentioned stereoscopic printing slurry is suddenly:
(1) by above-mentioned raw materials quality, polyethyleneglycol diacrylate, PMA, trimethylolpropane, polysiloxanes, chain extender, catalyst are added in reactor, stir and heat up, 50 ℃ of reactions 10 hours, make performed polymer;
(2) above-mentioned performed polymer is put in emulsifying kettle, cools to 20 ℃, add above-mentioned raw materials quality proportioning, after vinyl acetate stirs, rapid stirring, adds 500 kilograms of deionized waters, carries out emulsification, makes emulsion;
(3) while stirring toward the N-isobutoxy Methacrylamide, soda ash and the starch that add above-mentioned raw materials quality proportioning in emulsifying kettle, make pre-polymerization emulsion;
(4) above-mentioned pre-polymerization emulsion is joined in resin polymerization still, and add calgon, the sodium alginate of above-mentioned raw materials quality, stirring and dissolving is even, makes the aqueous solution;
(5) resin polymerization still is stirred and is warmed up to 65 ℃, carry out chemical reaction 10 hours;
(6) then cool to 20 ℃, stir 60 minutes, then filter blowing, obtain this product.
