Benefits of technology

The invention is a type of material made from elastomer that has good insulation properties against heat and solar energy, and is resistant to damage from hailstones and other weather phenomena. These properties make it a competitive option compared to other technologies.

Problems solved by technology

Although this product has market acceptance, it has functional deficiencies such as the volatilization and degradation of certain low-boiling oily components responsible for the plasticity of the product that seriously affects its mechanical properties, rendering the texture of the asphalt tile, hard and brittle, resulting in cracks and markedly lower impact resistance, which becomes evident when meteorological phenomena such as hail breaks the tile causing leaks, and the need to replace it.

[0020]Integrate synthetic rubber with an average particle size of 2.5 mm, polyunsaturated macromonomer of GAEA, styrene and Benzoyl peroxide in a batten mixer with the amounts described in Table 1, and mix at a speed of 40 to 100 rpm for a period of 15 minutes, until achieving the complete integration of the components in a homogeneous paste.

[0021]Feed the paste produced to a dosing unit of an endless screw connected to a pultrusion dice set at an inside temperature of 180° C. The pultrusion dice is also fed with kraft paper of 91.5 cm wide and 200 g / m2 by the lower part of the dice; this paper serves as a transport element of the paste.

[0022]Pull the kraft paper through a traction roller while the paste is fed simultaneously to the pultrusion dice set at 180° C. at a speed that allows the mixture to have a residence time in the pultrusion roller for at least 40 seconds.

Abstract

A prefabricated tile-type coating, whose manufacture is based on the development of a polymeric composite including mainly recycled synthetic rubber obtained from the grinding of scrap automotive waste tires, virgin rubber, or a combination of both, using as a binder a novel cross-linkable acrylic resin with the ability to be processed by pultrusion. The upper layer of the tile is made of a resin with thermochromic effect that integrates an encapsulated pigment of thermochromic material with a transition temperature in the range of 20-35° C. which changes color from white under high-temperature conditions, i.e. ° C. or greater than dark in conditions of low temperature, that is, 20° C. or less. The tile of elastomeric character obtained has notable competitive advantages compared to other technologies in terms of thermal resistance, solar reflectance, and resistance to the impact caused by hail or other meteorological phenomena.
