Abstract

The invention provides a hydrophobic masking tape and a preparation method thereof. The hydrophobic masking tape comprises a masking tape layer and an adhesive layer which is coated on the surface of the masking tape layer, wherein the adhesive formula of the adhesive layer comprises the following components in parts by weight: 200-300 parts of butyl acrylate, 100-200 parts of 2-ethylhexyl acrylate, 2-10 parts of acrylic acid, 2-10 parts of 2-hydroxyethyl acrylate, 30-60 parts of styrene-acrylic emulsion, 5-10 parts of sodium benzene sulfonate, 300-500 parts of water, 2-7 parts of ammonium persulfate and 0.1-0.5 part of sodium bicarbonate. A hydrophobic adhesive is adopted in a preparation process to remove the conventional organic solvent, and the masking tape is subjected to ultraviolet pretreatment, so that the produced masking tape is pollution-free and environment-friendly and has an outdoor use function.

Description

technical field [0001] The invention relates to a solvent-free water-based masking tape and a preparation method thereof. Background technique [0002] Masking tape is a high-tech decoration and spraying paper (also known as color separation tape because of its special properties), widely used in interior decoration, spraying of household appliances and spraying of high-end luxury cars. Masking tape is a roll-shaped adhesive tape made of masking paper and adhesive as the main raw materials. The adhesive is coated on the masking paper, and the other side is coated with anti-adhesive material. The color separation effect is clear and clear. It also has the effect of arc art, which has brought a new technological revolution to the decoration and spraying industry, and made the industry glow with new vitality. But at present, the adhesive of masking paper is generally made of volatile organic compounds such as benzene and toluene as solvents, which will produce toxic substances...
