Construcción de termoaislante a partir de papel con recubrimiento polimérico

Abstract

Thermal insulators are materials that prevent the transfer of heat from inside to outside or vice versa, there is a wide variety of insulating products, from those derived from polymers to agglomerates of natural products, many of these are pollutants and many others degrade, produce environmental damage. For this reason, a thermal insulator was generated from paper waste with a polymeric coating resulting from digital printing. To achieve this, two flame retardants, borax and (NH4) 2HPO4 are used, at the same time two types of binder, starch and cobalt are used, resulting in four test pieces, which are subjected to water absorption tests, temperature maximum, reaction to fire and anti fungal reaction. It was entitled that the test tubes, which has a variety of characteristics and that the probe is made with borax and starch gave the best results in the four tests carried out, which resists a temperature higher than 200 ° C, absorbs water without changing its characteristics physical, just as it loses the same amount of water in a week, a direct flame only burns superficially. When the tests are presented as examples of the conditions that can be exposed to the thermal insulation used in homes or businesses, it will be found that this insulator manufactured from the agglomeration of paper with polymeric coating, flame retardant and Binder, is an excellent candidate to replace polluting materials such as fiberglass or Styrofoam.
