Embodiment 1

[0024] Add 200mL deionized water into a 1000ML four-neck flask, start stirring, set the speed at 200rpm, and start heating. Add 30% deionized water to the pre-emulsification bottle, add 54g reactive emulsifier SR-10, 10g self-crosslinking monomer, 40g multifunctional polyester functional monomer, 240g butyl acrylate, 230g isooctyl acrylate while stirring , 40g acrylic acid, 10g hydroxyethyl acrylate, 290g methyl methacrylate, 230g styrene, stirred at high speed for 1 hour, and prepared the pre-emulsion for subsequent use; continue to heat the four-necked flask, and when the temperature of the four-necked flask rose to 80 degrees Celsius, Add 6g of reactive emulsifier and 1g of ammonium bicarbonate. When the temperature reaches 84 degrees Celsius, take 2% pre-emulsion and put it into a four-necked flask. Then add 1.2g of ammonium persulfate, until light blue appears in the four-necked flask, and the temperature is now stable at 85 degrees Celsius. Start to add the remaining pr...

Abstract

The invention relates to a PVC waterborne acrylate nanometer coating layer emulsion which is prepared from deionized water, an emulsifier, a self-crosslinking monomer, a multifunctional polyester functional monomer, butyl acrylate, 2-ethylhexyl acrylate, acrylic acid, hydroxyethyl acrylate, methyl methacrylate, styrene, a buffer agent, an initiator, an initiator A, sodium erythorbate, a defoamer and a pH regulator. For the emulsion, as a microemulsion polymerization method is adopted, the particle size of the emulsion is 60-100 nanometers, and the wettability and the adhesion force to a PVC substrate are both remarkably strengthened; and by using the reaction type emulsifier, the properties of a vehicle body PVC advertising consumable on the aspect of water resistance and weatherability are obviously improved.

Description

technical field [0001] The invention relates to a water-based acrylate emulsion, in particular to a PVC water-based acrylate nano-coating emulsion and a preparation method thereof. Background technique [0002] At present, a large number of PVC body advertisements and PVC electrical tapes on the market use solvent-based pressure-sensitive adhesives, or pre-coat water-based polyurethane coatings, and then apply water-based pressure-sensitive adhesives. Solvent-based pressure-sensitive adhesives do not meet the national environmental protection requirements due to the volatilization of a large amount of organic waste gas during the coating process. And its price of polyurethane coating is high, increased production cost. [0003] In view of the above-mentioned defects, the designer actively researches and innovates, in order to create a new type of PVC water-based acrylate nano-coating emulsion and its preparation method, so that it has more industrial value. Contents of th...
