Application of polyurethane in traffic vehicles

With the rapid development of the rail transit industry, there are increasingly higher requirements for the comfort, airtightness, shock absorption, and weight reduction of vehicles

Choose suitable adhesives for bonding and sealing on the material of the carriage, including glass bonding, floor bonding, caulking filling and sealing and waterproofing

Because polyurethane has high elasticity, adhesiveness and flexibility, as well as good resistance to vibration and impact, it has been widely used in rail vehicles.

Polyurethane adhesives because it contains polar, inert high isocyanate groups and urethane groups with active H-containing material having good chemical adhesion

Polyurethane adhesives are widely used in a variety of engineering vehicles, special vehicles, trains

Polyurethane glue can also be used as a welding seam sealing material and is a common choice for automobiles

Polyurethane adhesive has good construction process performance, good thixotropy, fast curing speed, low shrinkage rate, faster than PVC weld sealant curing speed, and can be used for welds with obvious dimensional changes during the drying process and joints with high strength requirements

Rail transit vehicles need to be repaired every 4-6 years, and paint will be repainted when they are repaired

After the research, we use the aliphatic hyperbranched polyester resin/hydroxy acrylic resin with excellent weather resistance as the base material to make the topcoat.

All the properties of high weather resistance and easy to clean polyurethane coatings can meet the relevant requirements of some standards, and can also meet a series of requirements such as weather resistance, abrasion resistance, scrub resistance, acid and alkali resistance, and scratch resistance

In addition to the above, polyurethane tires are also widely used in various vehicles

With the development of technology, the application fields of polyurethane composites have become more and more extensive.

In the future, we should continue to innovate independently, promote the development and application of polyurethane composite materials, and promote the sustainable development of the polyurethane industry
