DD264009A1 - NEW MIXTURE OF HIGH-MOLECULAR POLYMER MATERIALS FOR THE MANUFACTURE OF ANTIMYCOTIC PRODUCTS - Google Patents

Abstract

The invention has a new mixture of high molecular weight polymer materials for the production of antifungal products to the content. The invention can be applied in the rubber processing industry, preferably for the production of shoe insoles, bath mats, rubber boots u. ae. The object of the invention is achieved by adding a phyllosilicate adduct, which is loaded with antimycotics or disinfectants, to the mixture. Due to the carrier-bound antimycotics or disinfectants a high depot effect is achieved, whereby a long-lasting antifungal effect is guaranteed.

Description

Field of application of the invention

The invention relates to a novel mixture for the production of antifungal products from high molecular weight polymer materials, which is preferably used for the production of shoe insoles, bath mats and the like.

Characteristic of the known state of the art

The production of antimycotic products from high molecular weight polymer materials is known. The antifungal effect is caused by impregnation of carrier materials with various substances, such as e.g.

Disinfectants, medicinal herbs, antifungals. The use of the substances takes place in textiles, foams and plastics, as described in the following patents.

DD-PS 150884 describes insoles made of extruded, provided on both sides with sheet material foam, which is impregnated as an intermediate layer, for example, with antimycotics.

In DD-PS 230419 an insole is described which consists of the composite of a Polyolifinschaumes with textile and an antifungal equipment a.uf the basis of tetrachlorophenyl and a one- or two-sided compact barrier layer.

The water-impermeable barrier layer is made of thermoset, thermoplastic, Lefa o ^ he densified polyolefin foam DE-OS 3 215526 describes a hygienic insole to reduce the spread of fungal diseases, which is intended for single use. The production mainly takes place from natural raw materials, such as paper fiber material, cellulose, cotton wool, fleece, cotton, waste and recycling materials in one or more layers and contain active ingredients based on herbs.

In DE-OS 3324303 an insole is described which has island-like Bsschichtungszonen on its upper side, which consist of binder, solid and active ingredient.

The disadvantage of the o.g. Solutions of the known prior art consists in the insufficient persistent school effects against foot disorders.

The impregnation of textiles, foams and plastics with ingredients against diseases of the skin of the foreskin does not provide lasting or long-lasting protection. The active ingredients are subject to mass transfer by moisture or leaching, z. B. by foot sweat, weathering or cleaning with water or washing solution jngen.

Object of the invention

The aim of the invention is to describe a novel mixture of high molecular weight polymer materials for the production of antifungal products, which can be used under standard technological conditions and constantly ensures an antifungal effect of the products over a laiigen period.

Explanation of the essence of the invention

The invention has for its object to produce a mixture of high molecular weight polymer materials, which ensures a homogeneous distribution and relative binding of the antifungal agent in the mixture.

According to the invention the object is achieved in that an adduct consisting of phyllosilicates, which with specific ingredients z. B. are loaded against athlete's foot, added to the mixture based on natural and / or synthetic rubber

Magadiite are preferably used as sheet silicates.

According to the invention, the proportion of the layered silicate adduct is 0.1% by weight in% by weight, based on the total mass of the rubber mixture.

The degree of loading of the adduct with the specific ingredients is according to the invention 5 to 50 parts by mass in%.

As specific ingredients, antimycotics and disinfectants are preferably used.

The preparation of the mixture is carried out according to the prior art known Hochpolymerverarbeitungsverfahron.

The inventive solution a homogeneous distribution of antimycotics and disinfectants in the mixture was achieved and achieved by the adsorption of the substances in the vehicle, a long-lasting depot effect, whereby the antifungal effect is ensured over a long period.
