In a new study, a simple solution extension method for applying poly lactic acid (PLA) to psoria paper has been developed to give hydrophobic properties and to develop coating abrasive products using sustainable materials.
the study investigated and explored the possibility of using bio-based PLA as a permeable coating material on natural psoria paper to manufacture coated abrasive products and replace traditional non-biodegradable synthetic polymer-based impedance coating materials.
the PLA is applied to the dskin paper by solution coating to
. The barrier properties of PLA-treated psoria were tested accordingly to be used as a backing material in coated abrasive products. The concentration of PLA in the solution gradually increased from 5 wt% to 25 wt. The thickness of the coating and the weight of the coating increase quantitatively as the concentration of the solution increases.
use a scanning electron microscope (SEM), differential scanning heat method (DSC), contact angle and surface roughness measurements to characterize the shape of the coating. Quantify the mechanical properties of applied PLA-coated vinrup paper by measuring the strength of the opening, the strength of the rupture, the pore rate and the Cobb value to find it suitable as a coating abrasive product. Thermal analysis using DSC scanning showed the semicrystalline properties of PLA.
of air and water resistance to
coatings shows that air and water resistance increases with the thickness of the PLA coating. Data from different studies indicate that PLA coatings with a coating weight of 9 gm-2 appear to be the optimal concentration relative to unprocessed or other lower PLA gm-2 treated backing materials and have been shown to have excellent overall barrier properties, essentially required for the manufacture of coating abrasive products.
the study was published in August 2020 in volume 145 of Organic Coatings Progress.
