Abstract

The invention discloses a heat-resistant and anti-stripping pressure-sensitive adhesive, which is prepared from the following raw materials in parts by weight: 90 to 110 parts of 2-ethylhexyl acrylate, 70 to 90 parts of ethyl acetate, 40 to 60 parts of diacetone acrylamide, 30 to 50 parts of castor oil, 10 to 18 parts of methyl alcohol, 10 to 18 parts of silicane, 8 to 10 parts of chlorosulfonated polyethylene, 8 to 10 parts of emulsifying agents, 4 to 6 parts of magnesium acetate tetrahydrate, 1 to 2 parts of catalysts. 0.5 to 1.5 parts of zinc dimethyldithiocarbamate, and 0.2 to 1 part of antioxidant. A preparation method of the heat-resistant and anti-stripping pressure-sensitive adhesive comprises the following steps of S1, weighing the following raw materials in parts by weight according to a mixture ratio: 90 to 110 parts of the 2-ethylhexyl acrylate, 70 to 90 parts of the ethyl acetate, 40 to 60 parts of the diacetone acrylamide, 30 to 50 parts of the castor oil, 10 to 18 parts of the methyl alcohol, 10 to 18 parts of the silicane, 8 to 10 parts of the chlorosulfonated polyethylene, and 8 to 10 parts of the emulsifying agents, and sufficiently mixing the above raw materials, to obtain a pre-emulsion A; S2, adding the pre-emulsion into a reactor. The heat-resistant and anti-stripping pressure-sensitive adhesive is simple in preparation and convenient to operate; the problem that a common pressure-sensitive adhesive is poor in heat resistance is solved; the anti-stripping property is enhanced; the heat-resistant and anti-stripping pressure-sensitive adhesive is suitable for popularization.

Description

technical field [0001] The invention relates to the technical field of pressure-sensitive adhesives, in particular to a heat-resistant and anti-peeling pressure-sensitive adhesive. Background technique [0002] The full name of pressure-sensitive adhesive is pressure-sensitive adhesive, also commonly known as self-adhesive, referred to as pressure-sensitive adhesive. Pressure-sensitive adhesive products include three categories: pressure-sensitive adhesive tape, pressure-sensitive adhesive label paper, and pressure-sensitive film. Their full name is pressure-sensitive adhesive tape, pressure-sensitive adhesive label paper, pressure-sensitive adhesive sheet, commonly known as tape, self-adhesive label paper, pressure-sensitive film. Pressure-sensitive adhesives can be classified into five types according to their morphology: solvent-based pressure-sensitive adhesives, aqueous solution-type pressure-sensitive adhesives, emulsion-type pressure-sensitive adhesives, hot-melt pre...
