Phenolic resin, preparation method, sizing composition for mineral fibres and resulting products |
摘要 |
The present invention relates to a liquid phenolic resin, intended to be used in the formulation of a sizing composition for mineral fibres, essentially consisting of phenol-formaldehyde and phenol-formaldehyde-amine condensates and having a water dilutability at 20° C. of at least 1000%, and it has a free formaldehyde content of 0.3% or less and a free phenol content of 0.5% or less, the contents being expressed with respect to the total weight of liquid. The subject of the invention is also a method of manufacturing said resin, the sizing composition containing the resin and the insulating products based on mineral fibres sized by means of the aforementioned sizing composition. |
