Description
Фспо.| - формальдегиднын клей, примен емый обычно дл скленванн нзделий нз древесины, содержит значите.1ьное количество свободного фенола. Такое содержание свободного фенола вредно дл здоровь людей, работающих с этим клеем.Fspo | | - formaldehyde glue, which is usually used for wood scrubbing products, contains a significant amount of free phenol. This content of free phenol is harmful to the health of people working with this glue.
Кроме того, фенол-формальдегидный клей рекомендуетс дл склеивани древесины с влажностью только до 2%.In addition, phenol-formaldehyde glue is recommended for gluing wood with a moisture content of only 2%.
Клей, нолучаемый по оннсываемому способу, обладает высокой прочностью при склейке и отличаетс низким coдepжaниe свободного фенола, что нозво;1 ет использовать его в массовом производстве .The adhesive, which is obtained by the impregnated process, has a high strength at gluing and is characterized by a low content of free phenol, which means that it is used in mass production.
Предлагаемый клей рекомендуют дл склеивани древеснны с новышенной влажностью - до 30%.The proposed glue is recommended for gluing wood with a high moisture content of up to 30%.
Снособ нолучени такого кле заключаетс в следующем.The method for producing such glue is as follows.
В смс.ту, полученную способом, описанным в авт. eii. Х 88121, с содержанием свободного фенола не более 3%, ввод т кпс.чый каталпзатор - еульфокнслоту или другие кпс.юты в количестве, необходимом дл поддержани рН среды, равно .5-3,5.In sms.tu obtained by the method described in ed. eii. X 88121, with a free phenol content of not more than 3%, is administered to the cps. The catalpator — eulfonate or other cps. In the amount necessary to maintain the pH of the medium is .5-3.5.
Дл замедлени процесса нарастани в зкости кле во врем склеивани к нему добавл ют эти .товый спирт или нной растворнтель .To slow the buildup of the viscosity of the glue during bonding, this .good alcohol or a solvent is added to it.
Предмет изо б р е т е н п The subject of the invention
Способ полученн кле на основе фенол-формальдегидной смелые применением кислого катализатора , отличающийс тем, что. с целью уменьшени токсического действи кле , в качестве фено,фсрмальдегпдной смо.1ы нримеп ют смолу, полученную способом, онпсанным в авт. св. Лд 88121.The method of phenol-formaldehyde-based adhesive obtained is bold by using an acid catalyst, characterized in that. in order to reduce the toxic effect of the adhesive, as pheno, fmrmaldegpdnoy smooi, they apply the resin obtained by the method described in ed. St. Ld 88121.
