preparation example Construction

[0057] A second aspect of the present invention provides a method for preparing a hot-melt pressure-sensitive adhesive for a toilet gasket, the steps comprising:

[0058] (1) drop described naphthenic oil, antioxidant into stainless steel reactor;

[0059] (2) After the temperature rises to 140°C, add SBR rubber, and control the temperature of the reactor at 150°C;

[0060] (3) After the SBR rubber is completely dissolved, put in hydrogenated C5 / C9 copolymerized petroleum resin, modified aromatic C9 petroleum resin, styrene-acrylate, control the temperature of the stainless steel reactor within 200°C and stir for 30-60min, then vacuumize To -0.085MPa, the material is cooled and packaged.

Embodiment 1

[0064] Example 1 provides a hot-melt pressure-sensitive adhesive for toilet gaskets, including the following components: 8 parts of hydrogenated C5 / C9 copolymerized petroleum resin, 20 parts of modified aromatic C9 petroleum resin, 3 parts of styrene-acrylate, SBR 22 parts of rubber, 10 parts of naphthenic oil, 0.5 parts of antioxidant.

[0065] The hydrogenated C5 / C9 copolymerized petroleum resin is commercially available from Kolon, Korea, with the brand name SU-400.

[0066] The modified aromatic C9 petroleum resin is a product commercially available from Eastman Chemical, USA under the brand name of PiccoAR85.

[0067] The styrene-acrylic acid salt is styrene-acrylic acid sodium salt, and the preparation steps include:

[0068] (1): Add a certain amount of initiator azobisisobutylcyanide (AIBN), monomer styrene and acrylic acid in a four-necked flask, use benzene as a solvent, pass nitrogen to remove oxygen for 30 minutes, and then heat in a water bath at a temperature of...

Embodiment 2

[0080] Example 2 provides a hot-melt pressure-sensitive adhesive for toilet gaskets, including the following components: 15 parts of hydrogenated C5 / C9 copolymerized petroleum resin, 25 parts of modified aromatic C9 petroleum resin, 5 parts of styrene-acrylate, SBR 30 parts of rubber, 20 parts of naphthenic oil, 1 part of antioxidant.

[0081] The hydrogenated C5 / C9 copolymerized petroleum resin is commercially available from Kolon, Korea, with the brand name SU-400.

[0082] The modified aromatic C9 petroleum resin is a product commercially available from Eastman Chemical, USA under the brand name of PiccoAR85.

[0083] The styrene-acrylic acid salt is styrene-acrylic acid sodium salt, and the preparation steps include:

[0084] (1): Add a certain amount of initiator azobisisobutylcyanide (AIBN), monomer styrene and acrylic acid in a four-necked flask, use benzene as a solvent, pass nitrogen to remove oxygen for 30 minutes, and then heat in a water bath at a temperature of ...

Abstract

The invention relates to the technical field of polymer adhesives, and in particular to a hot-melt pressure-sensitive adhesive for a toilet seat gasket and a preparation method thereof. The hot-melt pressure-sensitive adhesive for the toilet seat gasket comprises hydrogenated C5 / C9 copolymerized petroleum resins. The hot-melt pressure-sensitive adhesive for the toilet seat gasket prepared by the invention has excellent cohesion strength while excellent coating performance is maintained, and meanwhile the product provided by the invention has good wettability to the substrate and is excellent in usage experience feeling.

Description

technical field [0001] The invention belongs to the technical field of polymer adhesives, and more specifically, the invention relates to a hot-melt pressure-sensitive adhesive for a toilet gasket and a preparation method thereof. Background technique [0002] Disposable toilet seat hot-melt pressure-sensitive adhesive is a hot-melt adhesive that is used to coat the surface of disposable toilet seat materials to prevent slippage and dislocation of disposable toilet seat materials on plastic toilet washers, and to play a fixed role. [0003] However, at present, with the improvement of people's requirements for comfort, the market has begun to use non-woven materials with better skin-friendly properties instead of paper materials to make disposable toilet mats. However, since the adhesion force between the skin-friendly material and the skin is to a large extent greater than that between the material and the toilet gasket, it greatly affects the user experience. In view of t...
