| description | La présente invention concerne des agents acides utilisables comme catalyseurs du durcissement des résols phénol-aldéhyde. Cet agent acide est un produit liquide non hydrosoluble résultant d'une interaction simultanée de : a. 1 mole d'un dérivé hydroxy-(R)-méthylique de phénol dans lequel à 1 mole du phénol correspondent de 0,4 à 2,0 moles de groupes HO-CH(R)- où R = H ou CH3 -, ou b. 1 mole de phénol et 0,3 à 2,0 moles d'aldéhyde, avec c. 0,03 à 100,0 moles d'un acide arylsulfonique ayant un indice d'acide de 10 à 300 mg.KOH
An acid agent comprises a liquid water-insoluble product of concurrent reaction of: (a) one mole of an hydroxy(R)-methyl derivative of phenol in which 0.4-2.0 moles of HO-CH(R)-groups are present per one mole of phenol, wherein R equals H-, CH3-, or (b) one mole of phenol and 0.3-2.0 moles of an aldehyde and (c) 0.03-100.0 moles of an aryl sulphonic acid, having an acid number from 10 to 300 (mg.KOH/g) with a maximum water content of 35% by weight. The process of reacting said components is conducted in a flow reactor for 0.1-10 minutes at 50 DEG -150 DEG C. The acid agent according to the invention may be modified with other substances, such as amines, alcohols, or acids to impart additional useful properties thereto. The acid agent has low viscosity, low corrosive activity, improves the strength of phenol-formaldehyde resins cured therewith by 30% and lowers their water absorption capacity by 2-10 times. |
