preparation example Construction

[0028] The present invention also provides the preparation method of the water-based pressure-sensitive adhesive, please refer to figure 1 , the preparation method comprises the steps of:

[0029] S11: Weighing the resin, the resin is composed of a first resin, a second resin and a UV monomer.

[0030] Wherein, when the UV monomer is hexanediol diacrylate, the quality of hexanediol diacrylate is 3.5-8% of the total mass of the resin; when the UV monomer is trimethylol propane tripropionate, the trihydroxy The mass of methylpropane tripropionate is 2-7% of the total mass of the resin, and when the UV monomer is triethylene glycol dimethacrylate, the mass of triethylene glycol dimethacrylate is 2.5% of the total mass of the resin -6%;

[0031] S12: adding an emulsifier and an initiator to the first resin and the UV monomer.

[0032] S13: Adding deionized water, and then stirring, and obtaining pre-emulsified monomer without delamination after standing still, the mass ratio of...

Embodiment 1

[0040] The resin is weighed, and the resin is composed of a first resin, a second resin and a UV monomer. The first resin composition is: methyl methacrylate, acrylic acid, butyl acrylate, and ethyl acrylate. The second resin composition is: butyl acrylate and methyl methacrylate.

[0041] In the first step, the first resin and UV monomer are pre-emulsified. The emulsifier is BYK306, and the addition amount is 1% of the total amount of the resin; the initiator is ammonium persulfate, and the addition amount is 1% of the total amount of the resin. 2.5%.

[0042] In the first resin, the addition of methyl methacrylate is 30% of the total amount of the resin, the addition of acrylic acid is 1% of the total amount of the resin; the addition of butyl acrylate is the total amount of the resin 42%, the addition of ethyl acrylate is 16% of the total amount of the resin;

[0043] The UV monomer is hexanediol diacrylate, and the addition amount is 3.5% of the total amount of the resi...

Embodiment 2

Abstract

The invention relates to the field of adhesives, and discloses a water-borne pressure sensitive adhesive. The water-borne pressure sensitive adhesive is made of raw material comprising resin, emulsifier and an initiator, wherein the resin comprises a UV (ultraviolet) monomer, the UV monomer is hexanediol diacrylate, trimethylolpropane tripropionate and triethylene glycol dimethacrylate, the weight of the hexanediol diacrylate is 3.5-8% of the total weight of the resin, the weight of the trimethylolpropane tripropionate is 2-7% of the total weight of the resin, and the weight of the triethylene glycol dimethacrylate is 2.5-6% of the total weight of the resin. The water-borne pressure sensitive adhesive has the characteristic of being high in stripping force, and can be used on polyvinyl chloride advertisement stickers.

Description

technical field [0001] The embodiments of the present invention relate to the field of adhesives, in particular to a water-based pressure-sensitive adhesive and a preparation method thereof. Background technique [0002] Acrylic pressure-sensitive adhesive is an acrylate copolymer obtained by copolymerizing various acrylate monomers. It is a very important type of resin-type pressure-sensitive adhesive. Compared with rubber-type pressure-sensitive adhesives, they have many advantages: the appearance is colorless and transparent and has good weather resistance; generally, good pressure-sensitive bonding can be obtained without the use of additives such as tackifying resins, softeners and anti-aging agents Performance; Copolymerization and crosslinking can be used to prepare pressure-sensitive adhesives that meet various performance requirements. In the past 20 years, this type of pressure-sensitive adhesive has developed very rapidly and has replaced the dominance of natural...
