example 1

[0012] The acrylate emulsion adhesive is prepared from the following raw materials in proportion by weight: 18.75% ethyl acrylate, 6.25% tackifying resin, 25% butyl acrylate, 6.25% other monomers, 6.20% acrylic acid, appropriate amount of ammonia water, emulsified Agent 1.88%.

[0013] Add the weighed water and emulsifier into the reaction kettle, stir and raise the temperature to 75°C, add 1 / 3 of the initiator aqueous solution and about 10% of the mixed monomer. Continue stirring to raise the temperature to 80°C and keep it warm for 1h. The temperature was lowered to 40°C, and the free monomers were blown away by blowing air. Add appropriate amount of ammonia water and tackifying resin, continue to cool to room temperature and discharge.

example 2

[0015] The acrylate emulsion adhesive is prepared from the following raw materials in proportion by weight: 20% ethyl acrylate, 16.75% tackifying resin, 29% butyl acrylate, 10.5% other monomers, 6.25% acrylic acid, appropriate amount of ammonia water, emulsified Agent 3.25%.

[0016] Add the weighed water and emulsifier into the reaction kettle, stir and raise the temperature to 75°C, add 1 / 3 of the initiator aqueous solution and about 10% of the mixed monomer. Continue stirring to raise the temperature to 80°C and keep it warm for 1h. The temperature was lowered to 40°C, and the free monomers were blown away by blowing air. Add appropriate amount of ammonia water and tackifying resin, continue to cool to room temperature and discharge.

example 3

[0018] The acrylate emulsion adhesive is prepared from the following raw materials in proportion by weight: 25% ethyl acrylate, 18.75% tackifying resin, 31.25% butyl acrylate, 12.5% ​​other monomers, 6.30% acrylic acid, appropriate amount of ammonia water, emulsified Agent 6.25%.

[0019] Add the weighed water and emulsifier into the reaction kettle, stir and raise the temperature to 75°C, add 1 / 3 of the initiator aqueous solution and about 10% of the mixed monomer. Continue stirring to raise the temperature to 80°C and keep it warm for 1h. The temperature was lowered to 40°C, and the free monomers were blown away by blowing air. Add appropriate amount of ammonia water and tackifying resin, continue to cool to room temperature and discharge.

Abstract

The invention relates to an acrylic ester emulsion adhesive. The acrylic ester emulsion adhesive has the advantages of rich sources of raw materials, convenience in synthesis and wide adhesion applicability, and can be applied to compound adhesion between paper and plastics. The acrylic ester emulsion adhesive is characterized by being prepared according to the following steps: adding weighed water and emulsifying agent into a reaction kettle; performing stirring and heating to 75 DEG C; adding 1 / 3 of initiating agent aqueous solution and about 10 percent of mixed monomer; continuously performing stirring and heating to 80 DEG C, performing heat preservation for 1 hour, and cooling to 40 DEG C; blowing away free monomer by means of blasting; adding an appropriate amount of ammonia water and tackifying resin; continuously cooling to a room temperature and carrying out discharging.

Description
