Sorbent material according to claim 1, characterized in that a polypropylene film is used as an oil and petrol resistant film.

Description

The utility model relates to materials for protection against the ingress of oil and oil products into the environment. The materials can be used as preventive means at potentially hazardous facilities: oil depots, automobile enterprises, air and sea transport enterprises, trunk pipelines and any enterprises whose activities are associated with the use of oil-containing liquids.

Known sorbent material described in the patent of the Russian Federation No. 2210644 by class. IPC DO4N 1/46, publ. 08/20/2003, including two fiber-reinforced layers of synthetic fibers bonded together by needle-piercing.

The sorbent material described in this patent, by its purpose and most of the essential features, is the closest analogue and can be taken as a prototype.

Known material has a high sorption and retention capacity, but when carrying out a number of works related to the use of petroleum products and their large accumulation in the material, it is possible to leak the petroleum product on one side of the sorbent material, by which it is laid on a protected surface. At the same time, the oil product may contaminate the surface on which it is laid.

The objective of the utility model is to increase the protective properties of the sorbent material while maintaining its high sorbing and retention abilities. The solution to this problem is achieved due to the fact that in the sorbent material, including two fibrous layers of different densities of synthetic fibers bonded to each other by needle piercing, on one of the outer surfaces the material contains a layer in the form of an oil-resistant film, and the ratio of the thicknesses of the two-layer and three-layer materials is mass .% from 1: 1 to 2: 1

As an oil and petrol resistant film, polyethylene GOST 10354-82 or polypropylene GOST 26996-86 films can be used.

According to a utility model, a base in the form of a two-layer needle-punched material made of synthetic fibers is duplicated with polyethylene or polypropylene films under certain technological parameters on a Ramish thermocalender. The ratio of the thicknesses of the two-layer and three-layer materials is regulated by the surface density of the two-layer material, depending on the further application.

Such a layer makes the sorbent nonwoven material impermeable to both water and petroleum products, i.e. necessary protective properties. The protective properties of the material were evaluated for water resistance in accordance with GOST 3816-81 “Textile fabrics. Methods for the determination of hygroscopicity and water-repellent properties. "

The feasibility of the utility model is illustrated by examples 1-3.

Example 1

A two-layer non-woven material was made from synthetic fibers of a certain surface density. The material was duplicated with a polypropylene film on a Ramish thermocalender at certain technological parameters. The ratio of the thicknesses of the two-layer and three-layer materials amounted to wt.% 2: 1.

Such sorbent material is intended as a shelter for riverbanks and ponds to protect against contamination with oil products or with small leaks of oil products. For example, in the form of napkins on the lids of the tanks when distributing fuel.

Example 2

A two-layer non-woven material was made from synthetic fibers of a certain surface density. The material was duplicated with a plastic film on a Ramish thermocalender at certain technological parameters. The ratio of the thicknesses of the two-layer and three-layer materials amounted to wt.% 1: 1.5.

Such sorbent material is intended as consumer mats that can be used in urgent car repairs and the like.

Example 3

A two-layer non-woven material was made from synthetic fibers of a certain surface density. The material was duplicated with a plastic film on a Ramish thermocalender at certain technological parameters. The ratio of the thicknesses of the two-layer and three-layer materials amounted to wt.% 1: 1,

Such sorbent material is intended as napkins that can be used during various types of equipment repairs at all enterprises.

The protective properties of the sorbent material were evaluated according to the indicator of water resistance.
