The new modified styrene butadiene latex has significantly improved its application performance in construction and road construction.

In terms of construction, the latex can be used to seal the joints between buildings and roads and repair cracks. The modified concrete has greatly enhanced performance, with a tensile strength greater than 5MPa, an impact strength increased by 1-5 times, a flexural tensile strength increased by 2-4 times, a wear resistance increased by 1-5 times, and water resistance and weather resistance also improved. This makes the structure of the building more stable, better able to resist erosion and impact from the external environment, and extend the service life of the building.

At the same time, it is inexpensive, has strong adhesion, is easy to mix with cement, is easy to construct, and can quickly form a film at room temperature, greatly improving construction efficiency and reducing construction costs. In road construction, modified styrene butadiene latex can be used for the paving of high-grade highway pavements, general highway pavements, and pedestrian bridge decks.

It can increase the service life of the pavement and reduce the brittle fracture of the pavement substrate. Adding a small amount of this latex to the pavement concrete can reduce, strengthen and toughen the concrete. Its flexural tensile strength is ≥5MPa, shear strength is ≥20MPa, compressive strength is ≥30MPa, and elastic modulus is >15GPa. These excellent performance indicators ensure that the pavement has better bearing capacity and anti-deformation ability, can effectively cope with the pressure and wear caused by vehicle driving, and improve the overall quality and performance of the road.
