Embodiment 1

[0064] In the 6L autoclave, drop into 1340 grams of 2,2-dimethylol propionic acid (C 5 h 10 o 4 , molecular weight 134), 40 grams of sodium formate, warming up to 155 ° C, began to drop ethylene oxide (C 2 h 4 O, molecular weight 44) 2200 grams of reaction, temperature control 155 ° C ~ 165 ° C, pressure 0.10 ~ 0.40 MPa, dropwise for 3 ~ 4 hours, after the drop is completed, 155 ° C ~ 165 ° C for 2 ~ 3 hours, and then cooled to 80 ° C Below, the crude product is obtained in discharging; after adding 40 grams of activated clay to the crude product and stirring for 30 minutes, the clear and transparent trihydroxy polyether ester (C 15 h 30 o 9 , molecular weight 354) 3469.2 grams, structure as shown in formula (Ia), wherein: n=2, a+b+c=5.

[0065]

[0066] In the 3000mL four-necked flask, drop into trihydroxy polyether ester (C 15 h 30 o 9 , molecular weight 354) 177 grams, IPDI 333 grams (1.5mol), catalyst dibutyltin dilaurate 0.2 grams, heat up to 60 ° C ~ 65 ° C, ...

Embodiment 2

[0071] 1000 grams of succinic anhydride, 15 grams of benzyltriethylammonium chloride, 1.5 grams of p-hydroxyanisole, and 3457 grams of trimethylolpropane diacrylate (molecular formula: C 12 h 18 o 5 , molecular weight 242, diester content by 70%), start stirring, heat up to 70°C, keep warm for 1 hour, then heat up to 80°C for 1 hour, then heat up to 100°C for 3 hours, react until the acid value is constant, and then After cooling to below 50°C, a bifunctional acrylate with a carboxyl group having the structure shown in formula IV is obtained.

[0072]

Embodiment 3

[0074] 600 kg of toluene, 350 kg of normal hexane, ethoxylated glycerin (C 9 h 20 o 6 , molecular weight 224) 618 kilograms, 655 kilograms of acrylic acid, 8 kilograms of p-hydroxyanisole, 9 kilograms of sodium hypophosphite, 55 kilograms of methanesulfonic acid; Open stirring, pass into compressed air continuously in the still by distributor at the bottom of the still, be heated up to Start reflux dehydration at 85-90°C, esterification reaction for 9-10 hours, kettle temperature 90-105°C, when reflux dehydration until no water comes out, detect acid value 25-30mgKOH / g, after the reaction is over, cool to 40°C; add 25 kg of caustic soda and 60 kg of water, stirred for 30 minutes; 6 kg of magnesium polysilicate was added, stirred and adsorbed for 30 minutes; then the water and solvent were distilled under reduced pressure at 50-95 °C under a vacuum degree of -0.098 MPa, and the recovered water After stratification with the solvent, the water can be used directly in the next neut...

Abstract

The invention discloses an EB-cured PUA textile sizing agent. The EB-cured PUA textile sizing agent is prepared from the following components in parts by weight: 10-20 parts of EB-cured resin, 70-80 parts of a reactive diluent, 1 part of a functional aid and 4-7 parts of a functional filler; and the EB-cured resin is urethane acrylate and carboxyl-containing acrylate, and the reactive diluent is acombination of one selected from EO3-GTA and EO3-TMPTA and one selected from PPG(400)DA, TPGDA and DPGDA. The invention discloses application of the EB-cured PUA textile sizing agent in yarn sizing.The urethane acrylate improves high-speed curing performance and good strength and wear resistance after film forming, the carboxyl-containing acrylate improves the good adhesive force and alkali solubility (easy desizing) after film forming, the reactive diluent is high in activity and good in flexibility, under EB irradiation, the drying speed of the yarn sizing agent is remarkably increased, energy is saved, the EB-cured PUA textile sizing agent is suitable for high-speed automatic production, and no pollution is achieved.

Description

technical field [0001] The invention belongs to the field of slurry for sizing textile yarns, and relates to an electron beam (EB) cured polyurethane acrylate (PUA) textile slurry and its preparation method and application, in particular to a polyurethane acrylate (PUA)-based and containing Carboxyl acrylate textile yarn sizing EB curing size and its preparation method and application. Background technique [0002] In textile processing, warp sizing must be done before the yarn is woven into cloth. The sizing can give the warp a smooth surface, improve its strength and wear resistance, and the warp sizing improves the weavability of the yarn, so that the yarn can Less broken heads, no hair. [0003] At present, the traditional thermal sizing process is usually used for yarn sizing. This process consumes a lot of energy. The heat energy consumed by sizing accounts for 50% of the heat energy consumption of cotton textile mills. The air consumption in the sizing process is the...
