Brief description of the treatment of phenolic the to prepare a material of construction lightweight, having very good characteristics mechanical, resistant to fire and a poor conductor of heat and material thus obtained.

摘要

P the invention relates to a process for the preparation of a light material, a poor conductor of heat and fire resistance and having very good mechanical characteristics. According to the invention, a phenolic resin liquid with an inert material, to a percentage of 100% to 30%, is added to 1% to 6% of a hardening agent, it is mixed for 15 to 50 seconds, the mixture is run into a mold having a volume of 1 to 2 times that of the mixture, it rests the mold at ambient temperature and pressure during 0,5 to 10 minutes, is introduced into an oven at 80 - 100°C. for 15 - 25 minutes, the object and is left in an environment at 80 - 100°C. for 45 - 95 minutes, and is extracted, the object of this environment. The attached drawing shows the diagram of the non - thermal conductivity of the material. The present invention applies in particular to the materials of construction. / p
