Problems solved by technology

[0004] Due to the limitations of polyurethane prepolymer synthesis technology, the main agent of polyurethane floor coatings generally has a high viscosity, which is inconvenient to operate during construction. Therefore, the currently commonly used method is to use organic solvents as diluents to facilitate spraying or scraping construction.
However, organic solvents are generally insoluble in water and have varying degrees of harm to the environment and the human body.
Generally speaking, the polyether structure on the polyurethane molecular chain determines that polyurethane products are flammable products, and in some occasions with high fire protection requirements, relatively strict requirements are set for the combustion performance of floor coatings, plus The way of auxiliary flame retardant can partially solve this kind of contradiction, but it will bring pollution of organic phosphorus or halogen

Abstract

The invention belongs to the technical fields of high-molecular materials and preparation technology, and concretely relates to a dual component floor paint with environmental protection and flame retardation and a preparation method thereof. The paint comprises the following components in percentages by weight: a component A: 30-45% of polyether polyol, 20-30% of polyester polyol, 10-20% of a plasticizer, 20-26% of MDI, and 0.4-0.6% of a dehydrating agent; a component B: 10-14% of MOCA, 10-20% of a plasticizer, 30-40% of polyether polyol, 30-35% of a fire retardant, 0.4-0.6% of a coupling agent, 1.0-2.0% of an antistatic agent, and 0.2-0.5% of color paste. The component A and the component B are uniformly mixed according to a ratio 1:1, and the dual component floor paint with environmental protection and flame retardation is obtained. The paint has the advantages of high strength, environmental protection and flame retardation, aging resistance and ultraviolet ray resistance. The paint can satisfy various requirements of planar construction, and is especially suitable for places of recreation, gas station and other places with environmental protection and flame retardation requirements.

Description

technical field [0001] The invention belongs to the technical field of polymer materials and their preparation, in particular to a two-component polyurethane environment-friendly flame-retardant floor coating and a preparation method thereof, and belongs to the field of chemical coatings. Background technique [0002] Polyurethane floor coatings refer to floor decoration materials that are synthesized from polyurethane raw materials, added with pigments, additives, and curing agents. Combined with specific construction techniques, polyurethane floor coatings can be made into floors that can meet certain specific requirements. Polyurethane flooring is easy to construct and can replace epoxy flooring. It is more wear-resistant and flexible, and different construction environments can focus on different index requirements. For example, high-end conferences or entertainment centers focus on comfort requirements; industrial and mining enterprises focus on anti-corrosion and Wear...
