Embodiment 1

[0008] The acrylic adhesive for rubber bonding includes, in parts by mass: 8 parts of methyl methacrylate-methyl acrylate copolymer, 7 parts of tricresyl phosphate, 15 parts of modified cellulose, 35 parts of acetone, triphenyl 0.3 parts of phosphine, 5 parts of tetraethylthiourea, and 0.04 parts of tributylamine. The preparation process is mixing and stirring. This one-of-a-kind acrylate adhesive for rubber bonding has a balance of tensile and shear strength. For different rubber materials, such as neoprene-melamine board, the average tensile strength is 5-6MPa, and the shear strength is good, with an average value of 3-4MPa.

Embodiment 2

[0010] The acrylic adhesive for rubber bonding includes, in parts by mass: 8 parts of methyl methacrylate-methyl acrylate copolymer, 10 parts of tricresyl phosphate, 15 parts of modified cellulose, 35 parts of acetone, triphenyl 0.4 parts of phosphine, 4 parts of tetraethylthiourea, and 0.02 parts of tributylamine. The preparation process is mixing and stirring. This rubber bond uses an acrylate adhesive with a balance of tensile and shear strength. For the same kind of rubber material, such as nitrile rubber, its tensile strength is 5MPa on average, and its shear strength is good, with an average value of 3MPa.

Abstract

The invention relates to an acrylic ester adhesive for bonding rubber, which comprises the components in parts by weight: 5-10 parts of methyl methacrylate-methyl acrylate copolymer, 5-10 parts of tricresyl phosphate, 10-20 parts of modified cellulose, 30-40 parts of acetone, 0.1-0.5 part of triphenylphosphine, 4-5 parts of tetraethyl thiourea and 0.01-0.05 part of tributylamine. The acrylic ester adhesive for bonding the rubber is capable of balancing tensile strength and shearing strength. The acrylic ester adhesive has the average tensile strength of 5-6MPa and good shearing strength with the average value of 3-4MPa for the different rubber materials.

Description

Technical field [0001] The present invention is a glue adhesive technology field, and especially involves an acrylic adhesive for rubber adhesion. Background technique [0002] Adhesive: Through the adhesion and internal agglomeration of the interface, two or more or more parts or materials can be connected together naturally or synthetic, organic, or inorganic.The agent, also known as adhesive, is used to glue for short.In short, adhesives are substances that can be combined with adhesion through adhesion."Adhesives" are general standard terms, including other glue, sludge, slurry, glue, and glue paste.For some difficulty in binding materials, such as polyethylene, polypropylene, rubber, polyvinyl chloride, have no comprehensive adhesives, either insufficient stretching strength, or insufficient shear strength. Invention content [0003] Solved technical problems: The present invention provides an acrylic adhesive for rubber adhesion to balance the tensile strength and shear st...
