| titleOfInvention | Production of phenolic resin foam |
| abstract | PURPOSE: To produce the title foam prevented from corroding a metal without detriment to the curing rate, cell structure, etc., by adding a silicate of a Group IIA element of the periodic table as a neutralizing agent to the system in the production of a resin foam by mixing a liquid resol phenolic resin with a blowing agent, a curing agent, etc. n CONSTITUTION: A phenol is coudensed with an aldehyde in the presence of an alkaline catalyst to produce a liquid resol phenolic resin. This resin is mixed with a blowing agent (e.g. trichloromonofluoromethane), a curing agent (e.g. phenolsulfonic acid), etc., and a silicate of a Group IIA element of the periodic table (e.g. calcium metasilicate) as a neutralizing agent is added to the system. As the metasilicate, one having a bulk density of 0.4-0.9g/cm 3 and a specific surface area ≤1.5m 2 /g is desirable. The obtained resin composition is poured into a mold and expanded by heating to obtain a phenolic resin foam. n COPYRIGHT: (C)1990,JPO&Japio |
