Embodiment 1

[0024] Add 5.0 kg of K12 emulsifier, 5.0 kg of OP-10 emulsifier, 180 kg of deionized water, 5.0 kg of methacrylic acid, 7.5 kg of glycidyl methacrylate, 225 kg of methyl methacrylate, 100 kg of One kilogram of butyl acrylate and 150 kilograms of isooctyl acrylate were fully stirred evenly to obtain a pre-emulsion. Then, 270 kg of deionized water, 35 kg of pre-emulsion and 1.0 kg of ammonium persulfate were added to the reactor, and the temperature was raised to 75° C. for polymerization. When there is obvious blue fluorescence in the reaction, add the remaining pre-emulsion and initiator solution (dissolved 1.5 kg of ammonium persulfate in 50 kg of deionized water) to the reaction kettle to adjust the rate of addition of the two , control the reaction temperature at 80-85°C, and dropwise addition is completed in about 3.5 hours. After the addition, keep warm for 30 minutes, then raise the temperature to 90-93°C and keep warm for 1 hour. After the temperature of the reaction ...

Embodiment 2

[0026] Add 4.0 kg of K12 emulsifier, 6.0 kg of OP-10 emulsifier, 180 kg of deionized water, 10 kg of acrylic acid, 5.0 kg of glycidyl methacrylate, 120 kg of methyl methacrylate, and 80 kg of benzene in the pre-emulsification kettle. Ethylene, 25 kg of ethyl acrylate, 110 kg of butyl acrylate and 140 kg of isooctyl acrylate were fully stirred evenly to obtain a pre-emulsion. Then, 270 kg of deionized water, 50 kg of pre-emulsion and 1.2 kg of ammonium persulfate were added to the reactor, and the temperature was raised to 82° C. for polymerization. When there is obvious blue fluorescence in the reaction, add dropwise the remaining pre-emulsion and initiator solution (1.8 kg of ammonium persulfate is dissolved in 50 kg of deionized water) to the reaction kettle to adjust the rate of addition of both , control the reaction temperature at 80-85°C, and dropwise addition is completed in about 2.5 hours. After the addition, keep warm for 30 minutes, then raise the temperature to 90...

Embodiment 3

[0028] Add 10 kg of DNS86 emulsifier, 180 kg of deionized water, 2.5 kg of methacrylic acid, 5.0 kg of glycidyl methacrylate, 80 kg of methyl methacrylate, 150 kg of styrene, and 100 kg of ethyl acrylate into the pre-emulsification kettle. Ester and 150 kilograms of isooctyl acrylate, fully stirred, obtained pre-emulsion. Then, 270 kg of deionized water, 45 kg of pre-emulsion and 1.0 kg of potassium persulfate were added to the reactor, and the temperature was raised to 90° C. for polymerization. When there is obvious blue fluorescence in the reaction, add dropwise the remaining pre-emulsion and initiator solution (1.6 kg of potassium persulfate is dissolved in 50 kg of deionized water) to the reaction kettle to adjust the rate of addition of both , control the reaction temperature at 80-85°C, and the dropwise addition is completed in about 3 hours. After the addition, keep warm for 30 minutes, then raise the temperature to 90-93°C and keep warm for 1 hour. After the tempera...

Abstract

The invention discloses polyacrylate hot-melt pressure sensitive adhesive for a polyethylene protective film and a preparation method thereof. The polyacrylate hot-melt pressure sensitive adhesive is prepared from polyacrylate hot-melt pressure sensitive adhesive emulsion by polymerization reaction and spray drying, wherein the polyacrylate hot-melt pressure sensitive adhesive emulsion comprises the following components in percentage by weight: 20-35% of soft monomer, 8-20% of hard monomer, 0.4-4% of functional monomer, 0.1-2% of emulsifier, 0.05-0.6% of initiator and 45-55% of deionized water. By using the polyacrylate hot-melt pressure sensitive adhesive disclosed by the invention, the polyethylene protective film with balanced initial viscous force, lasting viscous force, peel strength and cohesive force can be produced; and volatile organic compound is not discharged during the production and environmentally-friendly production of the polyethylene protective film can be realized.

Description

technical field [0001] The invention relates to a polyacrylate hot-melt pressure-sensitive adhesive and a preparation method thereof, more specifically, the invention relates to a polyacrylate hot-melt pressure-sensitive adhesive for polyethylene protective film and a preparation method thereof. Background technique [0002] Protective film is a surface protection and packaging material used to protect the surface of commodities. It is pasted on various metals, aluminum-plastic panels, plastic panels, coated steel, stainless steel panels, aluminum profiles, stone, glass, instruments, and furniture. Such as the surface of the commodity, so that it can protect the surface during manufacturing, transportation, secondary processing, storage and use, prevent the commodity from being polluted, scratched and slow down the oxidation of the commodity surface. The application of protective film can not only improve the appearance quality of products and facilitate material processing,...
