"Wear resistance" for factory and garage floors: acrylic-polyurethane coatings

In factories and garages, the floor has been subjected to the heavy pressure and frequent friction of vehicles and machinery for a long time, and the wear problem is prominent. Acrylic - polyurethane coatings are often used in floor coating, and its wear resistance has attracted much attention. How does it perform? Can it resist wear for a long time? The following is an in-depth analysis from a professional perspective.
Acrylate-polyurethane coatings are composed of acrylic resin and polyurethane resin. Acrylic resin weather resistant, light and color preservation, polyurethane resin wear resistance, impact resistance and strong adhesion, the combination of the two, complementary advantages.
The urethane bond (-NHCOO-) of polyurethane resin enhances the cohesion and flexibility of the material, and can disperse the stress when subjected to external force, preventing the local stress concentration to damage the material. The unsaturated double bond and side chain group of acrylic resin improve the hardness and chemical resistance of the coating, and further strengthen the wear resistance.The key indicators and performance of wear resistance of Acrylic Polyurethane Paint are shown as follows:
1. Hardness and wear resistance: the hardness of the pencil after solidification of the paint is usually 2H-4H, in the face of vehicles and mechanical friction, it can effectively resist scratch and wear. The simulated tire friction experiment shows that the surface wear of the coating is much lower than that of the ordinary floor coating, and it can maintain a good flatness.
2. Impact resistance and flexibility: Factory and garage floors will be affected by vehicle starting, braking and mechanical impact. Acrylic polyurethane coating has good flexibility, elastic deformation, energy absorption, avoiding cracking and falling off, rapid recovery after impact, and continuous wear resistance. Falling ball impact test shows that the coating can remain intact even under large impact.
3. Friction coefficient and wear mechanism: its friction coefficient is moderate, which not only ensures driving safety, but also does not aggravate wear due to high friction coefficient. When vehicles and machinery move, the molecular structure of the coating consumes friction energy by molecular sliding and elastic deformation of chemical bonds, and the microstructure also helps to reduce the friction coefficient and reduce wear.

In practical applications, acrylic polyurethane coatings perform well in the wear-resistant protection of factory and garage floors. Large factories such as automobile manufacturing, machining workshops, vehicles, machinery frequent, the floor with the coating, after many years of use can still maintain good condition, wear is much lower than other coatings.
An automobile manufacturing assembly workshop, the use of the paint for 5 years, although the vehicle, mechanical operation is frequent, the floor only slight wear, no sand, cracking, after testing, wear resistance can still meet the needs. The same is true in the field of garage, after the use of a commercial parking lot, after many years of frequent rolling and friction by vehicles, the floor surface is smooth, beautiful color, no obvious wear and loss of color.

At the same time, the wear resistance of acrylic polyurethane is also affected by the following two factors:
1. Construction technology: Construction technology has a great impact. Proper application ensures uniform coating and a dense coating. It is necessary to strictly control the amount of coating, drying time and curing conditions. Too thin coating can not provide enough protection, dry, poor curing will reduce the coating performance, wear resistance, professional construction and standard process is the key.
2. Use environment: Use environment is also important. High temperature, high humidity, chemical corrosion environment will affect its wear resistance. High temperature may cause thermal degradation of molecular structure, reduce hardness and wear resistance; High humidity is easy to cause hydrolysis and destroy chemical bonds; Acid base solution, organic solvent and other chemical media, may react with the coating, resulting in swelling, dissolution, embrittlement of the coating, accelerate wear. Therefore, the selection and use of environmental characteristics should be considered, and protective measures should be taken.
Acrylic polyurethane coating with its unique composition and structure, in the factory, garage floor wear protection excellent performance. Its high hardness, good flexibility, moderate friction coefficient, adapt to a variety of environments, can maintain long-term surface integrity, anti-wear. Combined with correct construction technology and reasonable use environment, it can provide reliable protection for the floor, extend the service life, reduce maintenance costs, and is a high-quality floor coating.
