Embodiment 1

[0021] like figure 1 As shown, the textured paper heat-pressing tape provided by the present invention has a textured paper layer 1, an acrylic adhesive layer 2, and a hot melt adhesive layer 3 in sequence from top to bottom. The formula of the acrylic adhesive layer is: 40 parts of methyl methacrylate; 30 parts of hydroxyethyl methacrylate; 2 parts of stabilizer; 2 parts of initiator; 15 parts of solvent. The formula of the hot melt adhesive layer is: 250 parts of ethylene-vinyl acetate copolymer, 35 parts of petroleum resin; 2 parts of pentaerythritol tetrakis(3,5-di-tert-butyl-4-hydroxy)phenylpropionate. The thickness of the masking paper layer is 100 μm; the thickness of the acrylic adhesive layer is 8 μm; the thickness of the hot melt adhesive layer is 12 μm. The masking paper heat-pressing tape of the present invention will not produce residual glue after peeling off.

Embodiment 2

[0023] like figure 1 As shown, the textured paper heat-pressing tape provided by the present invention has a textured paper layer 1, an acrylic adhesive layer 2, and a hot melt adhesive layer 3 in sequence from top to bottom. The formula of the acrylic adhesive layer is: 50 parts of methyl methacrylate; 20 parts of hydroxyethyl methacrylate; 1 part of stabilizer; 3 parts of initiator; 25 parts of solvent. The formula of the hot melt adhesive layer is: 200 parts of ethylene-vinyl acetate copolymer; 50 parts of petroleum resin; 4 parts of pentaerythritol tetrakis(3,5-di-tert-butyl-4-hydroxy)phenylpropionate. The thickness of the textured paper layer is 120 μm; the thickness of the acrylic adhesive layer is 5 μm; the thickness of the hot melt adhesive layer is 15 μm. The masking paper heat-pressing tape of the present invention will not produce residual glue after peeling off.

Embodiment 3

[0025] like figure 1 As shown, the textured paper heat-pressing tape provided by the present invention has a textured paper layer 1, an acrylic adhesive layer 2, and a hot melt adhesive layer 3 in sequence from top to bottom. 45 parts of methyl methacrylate; 25 parts of hydroxyethyl methacrylate; 3 parts of stabilizer; 13 parts of initiator; 10 parts of solvent. The formula of the hot melt adhesive layer is: 300 parts of ethylene-vinyl acetate copolymer, 21 parts of petroleum resin; 0.5 part of pentaerythritol tetrakis(3,5-di-tert-butyl-4-hydroxy)phenylpropionate. The thickness of the masking paper layer is 80 μm; the thickness of the acrylic adhesive layer is 6 μm; the thickness of the hot melt adhesive layer is 10 μm. The masking paper heat-pressing tape of the present invention will not produce residual glue after peeling off.

Abstract

The invention relates to an adhesive tape and particularly relates to a hot-pressing adhesive tape with beautiful-pattern paper. The adhesive tape comprises a beautiful-pattern paper layer 1, an acrylic acid adhesive layer 2 and a hot melt adhesive layer 3 in order from top to bottom. The adhesive tape is good in retentivity, free of adhesive residue, good in toughness, good in tension resisting effects, high in tensile strength and free of breakage.

Description

technical field [0001] The invention relates to an adhesive tape, in particular to a masking paper heat-pressing adhesive tape. Background technique [0002] Hot pressing tape is also called hot melt tape. It is different from pressure-sensitive tapes. At room temperature, heat-pressed tapes do not show pressure-sensitive adhesiveness, but have anti-blocking properties; however, after instant high-temperature heat-pressing, they produce 10 times the adhesive force of pressure-sensitive tapes . However, in the existing adhesive tapes that require high thickness, textured paper is often used as the base layer, but the adhesion between the base layer and the hot-melt adhesive layer is poor, and it is easy to degumming. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a masking paper heat-pressing tape with good adhesion and not easy to degumming. [0004] The technical problem to be solved by the present invention...
