Title: Innovations of Bernard Lericque
Introduction
Bernard Lericque is a notable inventor based in Rantigny, France. He has made significant contributions to the field of materials science, particularly in the development of resin compositions. With a total of three patents to his name, Lericque's work focuses on improving the properties and applications of phenolic resins.
Latest Patents
One of Lericque's latest patents is for a phenolic resin for glue sizing composition, which includes a preparation method and the glue sizing composition itself. This invention relates to a resin composition based on a urea-modified phenol-formaldehyde resole. The composition has a formaldehyde/phenol molar ratio of 2 to 5, with a free formaldehyde content lower than or equal to 3 percent by weight. Additionally, it features a free phenol content lower than or equal to 0.5 percent and a dilutability measured at 20°C of at least 1000 percent. The invention also describes a process for preparing this composition, which is characterized by the presence of an overcondensed resole obtained through the condensation of phenol, formaldehyde, and optionally urea in a basic medium. This modification allows for increased dilutability, making it suitable for applications such as sizing compositions for products based on mineral wool, while also reducing atmospheric pollution during use.
