Description

Antiskid and noise-resistant coating

Technical Field

The invention relates to a coating, in particular to a coating with anti-slip and anti-noise functions.

Background

With the development of economy, the decoration of building ground is more and more paid attention, and especially the decoration of home can be said to be of great importance. The types of ground decoration materials on the market are greatly enriched, and three types of ground materials commonly used at present are solid wood floors, artificial boards and stone tiles. These floors all have their own advantages, but safety is fundamental. The most common ground safety problem at present is ground skid resistance, which is especially prominent in public places. The importance of ground antiskid safety not only relates to the prevention of the harmfulness of slip and fall injury, but also relates to the relief of muscle tension, fatigue and mental stress generated by muscle tension and fatigue when people walk or work on wet and slippery ground. In basketball court, the decoration of the floor is also very exquisite, and the floor is beautiful, antiskid and wear-resistant.

At present, modified acrylics are mainly used in the basketball court floor coating, the skid resistance and the wear resistance of the basketball court floor coating are improved by adding a large amount of inorganic materials such as aluminum oxide, calcium carbonate and the like, but the synthesized coating can generate a plurality of hard dots after being coated on the basketball floor, and if the synthesized coating is carelessly dropped during strenuous exercise, the coating can cause skin scratch, so that the coating has certain danger, and meanwhile, most of the prior basketball court is close to a residential area, and loud noise can be caused during shooting, so that the life of residents is influenced.
