Problems solved by technology

[0005] However, during the development and use of water-based paint, people gradually found that water-based paint has poor flexibility after film formation, high brittleness, poor impact resistance, and poor adhesion to the floor. With the friction of automobile tires, the impact and heavy pressure of material transfer, etc., the paint film will be damaged and peeled off. If things go on like this, the marking lines will be blurred, and the role of marking marks cannot be provided for a long time

Abstract

The invention provides a water-based floor marking coating and a preparation method thereof. The water-based floor marking coating comprises a component A and a component B; the component A comprises,by weight, 35-55 parts of a waterborne polyurethane resin, 15-20 parts of a pigment, 15-25 parts of a filler and 0.1-0.3 part of an adhesion promoter; and the component B comprises an isocyanate curing agent. The design of the components and the mutual cooperation of the components at a specific ratio make the activation period and the curing speed of the coating balanced, so the coating is suitable for marking coating of floor surfaces such as workshops, underground garages, playgrounds, warehouses and the like, and a film formed after curing the coating has characteristics of high cross-linking density, good appearance, excellent base material adhesion, excellent flexibility, excellent wear resistance and excellent impact resistance, and can provide a long-lasting identification markingfunction for the floor surfaces.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a water-based floor marking paint and a preparation method thereof. Background technique [0002] In playgrounds, residential underground garages, factory workshops and warehouses, etc., in order to divide the area and play a marking role, the paint that has been painted on the floor is usually brushed on the coating. According to the solvent type, the marking paint can be divided into solvent-based and water-based. At present, the solvent-based marking paint is mainly used in the market in our country. [0003] The main film-forming substances of solvent-based line marking paint include epoxy resin and acrylic resin, etc. For example, CN107603378A discloses a road marking paint and its production method. The raw materials of said marking paint include 30 to 40 parts of thermoplastic acrylic resin, 5-10 parts of diethylene glycol ether acetate, 15-25 parts ...
