Embodiment 1

[0026] In a 500ml three-neck flask equipped with a stirrer, condenser, nitrogen protection and feeding device, add 70ml of deionized water and 3g of emulsifier sodium dodecylsulfonate (SDS), and heat to 70°C in a water bath. Add 0.5 g of initiator potassium persulfate (KPS), then add 67 g of methyl methacrylate (MMA), 30 g of butyl acrylate (BA), and 1 / 10 of the mixed monomers of acrylic acid (AA) 3 g, and react at 70 ° C After 0.5 hours, the remaining monomer mixture was added dropwise, and the polymerization reaction was carried out for 3.5 hours. Then the temperature was raised to 85° C. for 2 hours, and then cooled to room temperature. The solid content of the obtained aqueous emulsion is 60%, the latex particle size is 0.1 μm, the viscosity is 50 mPa·S, the peel strength is 410 N / m, and the storage stability is > half a year.

Embodiment 2

[0028] In a 500ml three-necked flask equipped with a stirrer, condenser, nitrogen protection and feeding device, add 70ml of deionized water and 1g of emulsifier sodium dodecylsulfonate (SDS), sulfonic acid succinates (BDS) 1g, heated to 70°C in a water bath. Add initiator potassium persulfate (KPS) 0.5 gram, then add the mixing unit of methyl methacrylate (MMA) 30g, ethyl methacrylate (EMA) 20g, butyl acrylate (BA) 46g, acrylic acid (AA) 4g 1 / 10 of the monomer, reacted at 70°C for 0.5 hours, then added the remaining monomer mixture dropwise, and polymerized for 3.5 hours. Then the temperature was raised to 85° C. for 2 hours, and then cooled to room temperature. The solid content of the obtained aqueous emulsion is 60%, the latex particle size is 0.1 μm, the viscosity is 55 mPa·S, the peel strength is 410 N / m, and the storage stability is more than half a year.

Embodiment 3

[0030] In a 500ml three-necked flask equipped with a stirrer, condenser, nitrogen protection and feeding device, add 70ml of deionized water and 2g of emulsifier sodium dodecylsulfonate (SDS), and heat to 70°C in a water bath. Add initiator potassium persulfate (KPS) 0.7 gram, add methyl methacrylate (MMA) 30g, butyl methacrylate (BMA) 5g, butyl acrylate (BA) 63g, the mixing unit of acrylic acid (AA) 2g then 1 / 10 of the monomer, reacted at 70°C for 0.5 hours, then added the remaining monomer mixture dropwise, and polymerized for 3.5 hours. Then the temperature was raised to 85° C. for 2 hours, and then cooled to room temperature. The solid content of the obtained aqueous emulsion is 60%, the latex particle size is 0.15 μm, the viscosity is 50 mPa·S, the peel strength is 390 N / m, and the storage stability is > half a year.

Abstract

A water polyacrylate emulsion for printing is prepared through proportionally mixing water, emulsifier, trigger, perspex, acrylic acid (methyl) acrylate, and polymerizing at 70-85 deg.C for 5-8 hr. Its advantages are high solid content, small diameter of emulsoid particles, low viscosity, high stability, non-toxic and no environmental pollution.

Description

technical field [0001] The invention relates to the design and manufacturing method of water-based polyacrylate emulsion for printing. technical background [0002] At present, the varnishes and inks used in the printing industry are mostly solvent-based, which have the serious disadvantages of poisoning human health and polluting the environment. As people pay more and more attention to the environment, it has become an inevitable trend for the printing industry to develop non-toxic and non-polluting water-based emulsions, so that such emulsions can be further formulated into printing water-based varnishes and water-based ink products. For this reason, it is a top priority to research and develop a replacement emulsion product with lower cost and excellent comprehensive performance. Contents of the invention [0003] Problem to be solved: [0004] In view of the above problems, the present invention provides a non-toxic, non-polluting high-solid-content polyacrylate aqu...
