Embodiment 1

[0026] 1) Pre-emulsification of monomers

[0027] Take 1.00g sodium dodecylsulfate and 0.5g sodium dodecylbenzenesulfonate in a small beaker with an electronic balance, then measure 8ml of water and put it in a small beaker, dissolve it under slight heat, and then Measure 2.6ml of polyethylene glycol octylphenyl ether (op) into a small beaker, and put the emulsifier into a three-necked flask after it is completely dissolved. Then measure 67ml of butyl acrylate, 18ml of isooctyl acrylate, 14ml of methyl methacrylate, 1.5ml of acrylic acid, and 3ml of N-methylol acrylamide in a three-necked flask, start stirring slowly to make it uniform, and then turn on high-speed stirring for about 1 ~1.5 hours to make a pre-emulsion.

[0028] 2) Polymerization

[0029] At room temperature, put the four-necked flask into a constant temperature water bath equipped with a thermometer, stirrer, condenser and cut-off thermometer. When the temperature rises to 40-60°C, add 75ml of water and a li...

Embodiment 2

[0038] 1) monomer pre-emulsification

[0039] Use an electronic balance to take 1.2g sodium lauryl sulfate, 1g fatty alcohol polyoxyethylene ether AEO-3, 1.3ml polyethylene glycol octyl ethyl ether, and 5ml water in a small beaker. Dissolve it fully, put it into a three-necked flask, and measure 61ml of butyl acrylate, 18ml of isooctyl acrylate, 4ml of 2-hydroxypropyl acrylate, 3ml of acrylonitrile, and 14ml of ethyl acrylate, put them into the three-necked flask, start slowly Stir at high speed to fully mix the emulsifier and monomer, then turn on high-speed stirring for about 1 to 1.5 hours to obtain a pre-emulsion.

[0040] 2) Aggregation

[0041] According to embodiment 1,2) polymerization method polymerization, initiator uses azobisisobutyronitrile, obtains the composition of aqueous resin emulsion by quality:

[0042] Water-based resin polymer accounts for 43% of the emulsion,

[0043] The emulsifier accounts for 3.4% of the polymer,

[0044] The rest is water (which...

Embodiment 3

[0049] 1) monomer pre-emulsification

[0050] Use an electronic balance to take 1.2g sodium lauryl sulfate, 1.5g sodium fatty alcohol polyoxyethylene ether sulfate, 1ml polyethylene glycol octylphenyl ether, and 5ml water in a 250ml small beaker. Slowly dissolve in a water bath to make an emulsion and pour it into a three-necked flask, then weigh 43ml of isobutyl methacrylate, 14ml of methyl methacrylate, 18ml of isooctyl acrylate, 2ml of acrylic acid, and 20ml of ethyl acrylate in the three-necked flask. In the flask, start stirring at a slow speed to fully mix the emulsifier and the monomer, and then start stirring at a high speed for about 1 to 1.5 hours to obtain a pre-emulsion.

[0051] 2) Aggregation

[0052] By embodiment 1,2) polymerization method polymerization, initiator uses dibenzoyl peroxide, obtains water-based resin emulsion by quality composition and is:

[0053] Water-based resin polymer accounts for 43% of the emulsion,

[0054] The emulsifier accounts for...

Abstract

The invention pertains to the technical field of polymer materials and particularly relates to a waterborne resin emulsion for car cleaning cloth or common cleaning cloth and a textile finishing adhesive agent, a synthetic method and application of the waterborne resin emulsion. The resin emulsion consists of a waterborne resin polymer, an emulsifier, an evocating agent, a pH value modulator and water; the waterborne resin polymer is obtained by polymerization of 3-5 monomers such as butyl acrylate, ethyl hexyl acrylate and methyl methacrylate and the like. The synthesis comprises two steps of monomer pre-emulsion and polymerization by the evocating agent. The product of the invention has stable performance and good film formation performance, as well as soft hand feeling, good moisture permeability, long-term moisture and environment protection by absorbing fine dusts when used as cleaning cloth, and when used as a textile adhesive agent, the product can not only realize the characteristics and requirements above, but also decrease electrostatic interaction of the textile, thus having good and wide application in the textile field.

Description

Technical field: [0001] The invention belongs to the technical field of macromolecular materials, and in particular relates to a water-based resin emulsion that can be used for automobile or civil wipes and textile finishing adhesives, a synthesis method and application of the water-based resin emulsion. Background technique: [0002] Acrylate emulsions are widely used in paints, coatings, adhesives, fabric finishing, leather finishing and automotive industries due to their excellent performance. Water-based resins are not only widely used in the above fields, but also have unique effects in the automotive field. Before the surface of the car is painted, grinding and polishing processes are often used, accompanied by a large amount of dust emission, which not only pollutes the environment, but more importantly, causes great harm to the physical and mental health of workers. If dust remains on the surface of the car, it can seriously affect the performance of the coating. I...
