Description

Способ имеет целью изготовление продукта из отбросов хромовой и краснодубной кожи в смеси с корой пробкового или корой иных деревьев. Дл  осуществлени  предлагаемого способа берут мелко измельченную пробку или кору деревьев, по своим свойствам близко подход щую к ней, и обрабарьшают слабыми растворами сульфоновых органических или минеральных кислот, или растворами кислых солей, или солей щелочноземельных и др. т желых металлов. К подготовленной массе прибавл етс  раствор белков или их смесь с кератиновыми веществами или только кератиновые вещества, предварительно обработанные жидкими продуктами конденсации фенола или его гомологов с формальдегидом , при чем все тщательно перемешиваетс . Затем вводитс  кожана  стружка , снова перемешиваетс  со всей смесью и обрабатываетс  одним из вышеуказанных кле щих веществ, после чего смесь прессуетс  дл  удалени  воды и придани  ей однородности и формы. При этом получаетс  весьма пластичный, легкий и упругий материал, который по высыхании становитс  твердым, прочным и обладает способностью полироватьс . Если же полученный таким путем материал подвергнуть прессованию в обогреваемых прессах, то твердость и прочность его значительно повышаютс , а также при этом приобретаетс  им и высока  устойчивость к воде.The method aims to manufacture a product from the garbage of chrome and red-tan skin mixed with cork bark or bark of other trees. To carry out the proposed method, finely chopped cork or tree bark, which is close to it in its properties, is taken and treated with weak solutions of organic sulfonic or mineral acids, or solutions of acid salts, or alkaline earth salts and other heavy metals. To the prepared mass is added a solution of proteins or their mixture with keratin substances or only keratin substances previously treated with liquid condensation products of phenol or its homologs with formaldehyde, and everything is thoroughly mixed. The leather chips are then introduced, mixed again with the whole mixture and treated with one of the above-mentioned adhesives, after which the mixture is pressed to remove water and make it uniform and uniform. This results in a very flexible, lightweight and resilient material, which upon drying becomes hard, durable and has the ability to polish. If, however, the material thus obtained is subjected to pressing in heated presses, then its hardness and strength increase significantly, and at the same time it also acquires high resistance to water.

Предмет изобретени .The subject matter of the invention.

1.Прием выполнени  способа получени  пластических масс, указанного в патенте .NO 15368, с применением растворов кератиновых или белковых веществ или их смеси, обработанных начальными продуктами конденсации фенола или его гомологов с формалином, от.ичающийс  тем, что кору пробкового или других деревьев предварительно обрабатывают слабыми растворами сульфоновых кислот.1. Acceptance of the method for producing plastics, mentioned in the patent NO 15368, using solutions of keratin or protein substances or their mixtures treated with the initial condensation products of phenol or its homologs with formalin, since the bark of cork or other trees is preliminary treated with weak solutions of sulfonic acids.

2.Прием выполнени  указанного в п. 1 способа, отличающийс  тем, что к измельченной коре пробкового или других деревьев прибавл ют кожаную стружку.2. Acceptance of the method indicated in claim 1, characterized in that leather chips are added to the crushed bark of cork or other trees.
