preparation example Construction

[0042] The present invention also provides a kind of preparation method of adhesive, and it comprises the steps:

[0043] S1. Weigh each raw material component according to the corresponding parts by mass.

[0044] Wherein, each raw material composition ratio is as follows:

[0045]

[0046] The hard monomer is selected from at least two of methyl acrylate, methyl methacrylate and glycidyl methacrylate, and the functional monomer is selected from at least two of hydroxyethyl acrylate, acrylic acid and acrylamide , and the functional monomer needs to contain hydroxyethyl acrylate.

[0047] S2. Mix butyl acrylate, hard monomers, functional monomers and a part of the solvent to obtain a mixture.

[0048] Mix the butyl acrylate, the hard monomer, the functional monomer and a part of the solvent until uniform, and further, mix the butyl acrylate, the hard monomer, the functional monomer and a part of the solvent until uniform by stirring. Further, the addition amount of this ...

Embodiment 1

[0073] A preparation method of high temperature resistant acrylate adhesive, it comprises the steps:

[0074] 229 g of butyl acrylate, 15 g of hydroxyethyl acrylate, 35 g of methyl acrylate, 15 g of glycidyl methacrylate, 3 g of acrylic acid, 3 g of acrylamide, 80 g of toluene, and 320 g of ethyl acetate were charged into the reactor. Under the condition of stirring, pass nitrogen gas to remove the air in the reactor, put in 0.3g of azobisisobutyronitrile, 66-67°C, keep the temperature for 2 hours; continue to put in 0.5g of azobisisobutyronitrile, Keep the temperature and react for 3 hours; add 0.8g of azobisisobutyronitrile, and keep the temperature for 2 hours under the condition of 78-80°C; cool and add 300g of solvent ethyl acetate to obtain a high temperature resistant acrylate adhesive.

Embodiment 2

[0076] A preparation method of high temperature resistant acrylate adhesive, it comprises the steps:

[0077] 217 butyl acrylate, 21 g of hydroxyethyl acrylate, 35 g of methyl acrylate, 20 g of glycidyl methacrylate, 3.5 g of acrylic acid, 3.5 g of acrylamide, 100 g of toluene, and 300 g of ethyl acetate were charged into the reactor. Under the condition of stirring, pass nitrogen gas to remove the air in the reactor, put in 0.2g of azobisisobutyronitrile, 66-67°C, keep the temperature for 2 hours; continue to put in 0.4g of azobisisobutyronitrile, Keep the temperature and react for 3 hours; continue to add 0.8g of azobisisobutyronitrile, and keep the temperature for 2 hours under the condition of 78-80°C; cool and add 300g of ethyl acetate as a solvent to obtain a high temperature resistant acrylate adhesive.

Abstract

The invention relates to an adhesive and a preparation method thereof, a pressure-sensitive adhesive tape and a preparation method thereof. The adhesive comprises the following raw material componentsin parts by mass: 20-35 parts of butyl acrylate, 4-10 parts of a hard monomer, 0.4-1 part of a functional monomer, 0.1-0.5 part of an initiator and 60-70 parts of a solvent, wherein the hard monomeris selected from at least two of methyl acrylate, methyl methacrylate and glycidyl methacrylate, the functional monomer is selected from at least two of hydroxyethyl acrylate, acrylic acid and acrylamide, and the functional monomer contains hydroxyethyl acrylate. According to the adhesive, the hard monomer, the functional monomer, a soft monomer butyl acrylate and other raw material components arereasonably combined to form good physical crosslinking, so that heat resistance of the adhesive is remarkably improved, and no residual is left after the adhesive is attached to a product.

Description

technical field [0001] The invention relates to the technical field of pressure-sensitive adhesive tapes, in particular to an adhesive and a preparation method thereof, a pressure-sensitive adhesive tape and a preparation method thereof. Background technique [0002] Solvent-based acrylic pressure-sensitive adhesives are mainly polymerized from acrylates and other vinyl monomers. It is a viscoelastic material with both liquid and solid properties. Wet, and with the cohesive strength of a solid, it is widely used in daily life and commercial products, such as automotive, electronics, packaging, medical and transportation. [0003] However, with the development of the pressure-sensitive adhesive industry and the continuous expansion of the application range, pressure-sensitive adhesives are also facing various challenges, such as poor high temperature resistance, poor electrolyte resistance, poor acid and alkali resistance, and so on. In particular, the structural characteris...
