Abstract

The invention discloses a water-based acrylate pressure-sensitive adhesive for automobile protective film, which is composed of the following ingredients in parts by weight: 180-200 parts of soft monomer, 60-80 parts of hard monomer, 25-45 parts of functional monomer, 3-5 parts of emulsifier, 0.5-0.8 parts of initiator, 0.8-1.2 parts of curing agent and 320-350 parts of deionized water; the functional monomer includes fluorine-containing acrylate and compound I; adding fluorine-containing acrylate It can significantly improve the heat resistance and cold resistance of the acrylate pressure-sensitive adhesive, and the addition of compound I can significantly improve the tensile fracture resistance of the acrylate pressure-sensitive adhesive. The water-based acrylate pressure-sensitive adhesive of the present invention can not only effectively protect the car paint on the car surface from unnecessary damage when applied to the car protective film, but also can be repeatedly torn and pasted without damaging the car paint or sticking glue.

Description

technical field [0001] The invention relates to the technical field of pressure-sensitive adhesives, in particular to a water-based acrylate pressure-sensitive adhesive for automobile protective films and a preparation method thereof. Background technique [0002] Since the birth of automobiles, human pursuit of automobile maintenance has never stopped. In order to keep the car as bright as new, people have thought of many ways, and waxing, which improves the brightness of the paint surface and reduces the damage of the paint surface, was born. In order to pursue a longer-term and effective protection effect, there has been the emergence of sealing glaze and coating technology. However, with the development of science and technology, we have more and more requirements for car body maintenance, which should be simpler, more practical and more fashionable, so the body paint film was born along with the trend. [0003] Pressure-sensitive adhesive is a type of adhesive that is...
