Abstract
Description
Изобретение относится к легкой промышленности, а именно к кожевенному производству, и может использоваться для получения окрашенного полуфабриката. The invention relates to light industry, namely to the leather industry, and can be used to obtain a colored semi-finished product.
Известно окрашивание кож аминосмолами (Патент 2060335, РФ. Способ получения структурно-окрашенных аминосмол. Чурсин В.И., Илюхина О.А., МПК С 14 С 3/08). Наиболее близким по технической сути к предлагаемому изобретению является состав для крашения на основе полигексаметиленгуанидина (метацида) (Патент 2131443, РФ. Способ получения полимерных продуктов для обработки кожи. Попова Е.Н., Кошелева О.Э., МПК С 14 С 3/22)- прототип, где для получения красителя требуется проведение реакции азосочетания. Known staining of skin with amino resins (Patent 2060335, Russian Federation. A method for producing structurally colored amino resins. Chursin V.I., Ilyukhina O.A., IPC С 14 С 3/08). The closest in technical essence to the proposed invention is a composition for dyeing based on polyhexamethylene guanidine (metacide) (Patent 2131443, RF. Method for producing polymer products for skin treatment. Popova EN, Kosheleva OE, IPC C 14 C 3 / 22) is a prototype where, to obtain a dye, an azo coupling reaction is required.
Целью предлагаемого изобретения является упрощение процесса, повышение технологичности производства кож, экономия воды и материалов. The aim of the invention is to simplify the process, increase the manufacturability of leather production, save water and materials.
Указанная цель достигается тем, что в качестве основы для получения красящего материала применяются гидроксилсодержащие ароматические производные полигексаметиленгуанидина, имеющие интенсивную окраску. This goal is achieved in that the hydroxyl-containing aromatic derivatives of polyhexamethylene guanidine having intensive coloring are used as the basis for the preparation of the coloring material.
Предлагаемый состав получается следующим образом. The proposed composition is obtained as follows.
Полигексаметилен гуанидин (ПГМГ) обрабатывают раствором формальдегида (мольное соотношение 1:4) в 0,01 н. растворе буры при 45-100oC в течение 6-8 ч. После снижения/нагревания (при необходимости) температуры до 60oC в реакциионную смесь вводят оксиароматические соединения (α -нафтол, резорцин) в количестве, эквимолярном ПГМГ. Полученный продукт отмывают от непрореагировавших соединений до отрицательной реакции на фенолы.Polyhexamethylene guanidine (PHMG) is treated with a solution of formaldehyde (molar ratio 1: 4) in 0.01 N. borax solution at 45-100 o C for 6-8 hours. After lowering / heating (if necessary) the temperature to 60 o C, hydroxyaromatic compounds (α-naphthol, resorcinol) are introduced into the reaction mixture in an amount equimolar to PHMG. The resulting product is washed from unreacted compounds to a negative reaction to phenols.
Синтезированные продукты имеют интенсивную окраску, обусловленную строением олигомера, в котором между оксигруппами и иминогруппами ПГМГ образуются многочисленные водородные связи. The synthesized products have an intense color, due to the structure of the oligomer, in which numerous hydrogen bonds are formed between the hydroxy groups and the imino groups of the PHMG.
Пример 1. В реакционную колбу вносят 70,5 мас.ч. ПГМГ, 146 мл формалина и 125 мл 0,01 н. раствора буры. Синтез ведут 6-8 ч при постоянном перемешивании до исчезновения запаха формальдегида. При необходимости температуру снижают/повышают до 60oС, засыпают 72 мас.ч. α -нафтола, реакцию продолжают еще 2 ч. Полученную смолу отмывают от непрореагировавшего α -нафтола этилацетатом. Смола имеет темно-коричневый цвет.Example 1. In the reaction flask contribute 70.5 wt.h. PHMG, 146 ml of formalin and 125 ml of 0.01 N. borax solution. The synthesis is carried out for 6-8 hours with constant stirring until the smell of formaldehyde disappears. If necessary, the temperature is lowered / increased to 60 o C, 72 wt. α-naphthol, the reaction is continued for another 2 hours. The resulting resin is washed from unreacted α-naphthol with ethyl acetate. The resin has a dark brown color.
Пример 2. В реакционную колбу вносят указанные в примере 1 реагенты. После синтеза в течение 6-8 ч, снижения/повышения температуры до 60oС вносят 72 мас.ч. резорцина и продолжают реакцию еще 2 ч. Затем смолу отмывают этилацетатом, она имеет красный цвет.Example 2. In the reaction flask make the reagents indicated in example 1. After synthesis for 6-8 hours, lowering / raising the temperature to 60 o With contribute 72 wt.h. resorcinol and continue the reaction for another 2 hours. Then the resin is washed with ethyl acetate, it has a red color.
Кожевенный полуфабрикат, обработанный полученными модификатами ПГМГ, приобретает окраску после наполнения-додубливания смолами без проведения процесса крашения другими красителями для кожи. По примеру 1 кожа окрашивается в коричневый цвет, по примеру 2 - в красный. Окраска устойчива к сухому и мокрому трению, воздействию органических растворителей. The tanning semi-finished product treated with the obtained PGMG modifiers acquires a color after filling-retanning with resins without dyeing with other dyes for the skin. According to example 1, the skin is painted brown, according to example 2 - red. Coloring is steady against dry and wet friction, influence of organic solvents.
