Description

Technical field [0001] The invention relates to an adhesive for reflective coatings, in particular to a water-based acrylate adhesive for reflective coatings and a preparation method thereof. Background technique [0002] Road signs on highways generally have reflective functions to provide safety guarantees for vehicles driving on these highways at night. Such signs are made by coating reflective paint on the road surface. Reflective coatings can be divided into two types: water-based and solvent-based. With the enhancement of people's environmental protection and safety awareness and the implementation of relevant national policies and regulations, solvent-based reflective coatings are used less and less, and water-based reflective coatings with environmentally friendly characteristics are gradually being obtained. Pay attention and apply. [0003] Water-based reflective coatings generally consist of reflective materials, water-based binders, titanium dioxide, additives and wat...
