Abstract

The invention relates to an acrylate emulsion pressure-sensitive adhesive for beautiful textured paper masking tapes, and a preparation method thereof. The provided acrylate emulsion pressure-sensitive adhesive is prepared from the following components through a pre-emulsification semi-continuous polymerization technology: 2-ethylhexyl acrylate, butyl acrylate, methylbutyl acrylate, 2-hydroxypropyl acrylate, carboxyl-containing functional monomers, internally-crosslinked polyacrylate monomers, and a chain transfer agent. The prepared acrylate emulsion pressure-sensitive adhesive has the advantages of high solid content, low gel content, and good stability, and can be used as a single-component adhesive directly.

Description

technical field [0001] The invention belongs to pressure-sensitive adhesives, in particular to an acrylate emulsion pressure-sensitive adhesive for masking tape and a preparation method thereof. Background technique [0002] Masking tape is widely used in interior decoration, spraying of household appliances, shielding protection of electronic circuit boards and spraying of high-end cars. Masking tape is composed of masking paper and pressure-sensitive adhesive, and the pressure-sensitive adhesive is coated on the masking paper. Its color separation effect is clear and clear, and it also has an arc art effect, which has brought a new technological revolution to the decoration and spraying industry, and made the industry glow with new vitality. However, the adhesives used for masking tapes currently contain organic solvents, such as toluene and benzene, which pollute the environment and are not good for the human body. [0003] CN 102226068 describes a masking tape adhesive...
