Description

The invention relates to auxiliary equipment, for example, in vehicles, in particular for automobiles, and is used to increase the comfort of vehicle operation, as well as to prevent corrosion of the vehicle underbody in the passenger compartment.

A floor mat for a car is known, consisting of an upper water-permeable layer made with holes over the entire surface and reliefs on the lower side, the base being made of three layers, the upper of which is water-permeable, the middle one is absorbent, and the lower one is waterproof and vapor permeable from the side car floor (patent for utility model RU 50482 U1, 2006).

Known mat for the car, made of flexible, elastic single-layer or multilayer material, the boundaries of which are thickened, and on its surfaces are made recesses in the shape of a truncated cone, directed inside the mat. Cellulose fibers with helium granules or cotton with polyester are used as absorbent material.

The disadvantages of the known floor mats are insufficiently high protection of the vehicle interior from moisture accumulation, prevention of corrosion of the vehicle body and sanitary conditions in the vehicle interior.

A car mat is known, consisting of three layers: the upper one is permeable made of hydrophilic non-woven material made of polymer fibers, the middle one is waterproof, which is a packet of sheets of non-glued paper, and the lower layer is a waterproof sheet of polymeric material (patent RU 2284271, 2006 )

The disadvantages of this invention should be recognized low performance mat and a small resource of operation.

The closest analogue of the invention is an absorbent universal car mat containing a permeable layer of a hydrophilic non-woven material made of polymer fibers, a water-absorbing layer and a waterproof layer connected along the perimeter, while the permeable layer is made of non-woven needle-punched material, an antistatic polymer mesh is located above it and the water-absorbing layer consists of non-woven materials with a distribution layer, an absorbent layer made of fluffy cellulose and another distribution layer, for example, paper, and following it the waterproof layer is made of laminated paper, wherein a waterproof layer is a layer of needled non-woven material (RU 2324609, 2008).

The disadvantages of this invention include the low performance of the mat and the short life.

The technical task of this invention is the creation of a reusable absorbent car mat with high performance, including preventing corrosion of the vehicle, retaining moisture and oil products that have a destructive effect on the coating of the passenger compartment, high wear resistance, repeated use, improving the environment and comfort in the passenger compartment .

A distinctive feature of the proposed absorption mat is the ability of the product to hold a greater amount of liquid, and together with the liquid - a greater amount of harmful impurities, such as salt, chemicals, oils and other petroleum products, preventing them from evaporating with water and entering our body through respiratory the way.

The problem is solved due to the fact that a reusable moisture-absorbing mat (autopampers) containing a water-permeable layer made of polymer fibers of a non-woven hydrophilic needle-punched material, over which an antistatic polymer mesh is located, a water-absorbing layer made of non-woven material, and a waterproof layer, under which is located permeable layer, all layers interconnected around the perimeter, in accordance with the invention, the water-absorbing layer is made in the form of a multilayer sheet and, further comprising a hydrophilic antiseptic layer, an absorbent layer provided with a superabsorbent (SAP), while a notch is made on the absorbent layer, which serves as directing channels for the liquid, in addition, there are bumpers on all sides of the multilayer diaper, limiting the water-absorbing zone, and all diaper layers fastened together by firmware into a single whole, forming a monolithic mass, the waterproof layer is made of polyethylene or polypropylene film, and the permeable layer below it is made n made of polyester non-woven absorbent material.

The polymer antistatic mesh is made of a thickness of 3-5 mm with hollow cells, the size of each is 8 × 35 mm and with a thickness of jumpers of 3-5 mm.

Consider in more detail the proposed design of the mat.

The top layer, which is a polymer antistatic mesh, is 3 ... 5 mm thick, with hollow cells, the size of each cell is 8 × 35 mm and the thickness of the jumpers between them is 3 ... 5 mm. The grid is connected to a subsequent layer. This design of the top layer of the mat gives it flexibility and strength.

In addition, it is intended for cleaning shoes from dirt, snow, oil products, salt, chemicals, oil and water drops.

The next layer is a water-permeable layer made of non-woven material made of polymer, polyester, cotton or viscose fibers, and protects the next water-absorbing layer of the mat from mechanical damage from above and keeps mechanical particles (for example, grains of sand) on its surface.

Then there is a water-absorbing layer, which is a multilayer moisture-absorbing diaper, further comprising a hydrophilic antiseptic layer, an absorbent layer equipped with a superabsorbent (SAP). The main purpose of the water-absorbing layer is to absorb moisture penetrating through the upper layers of the mat. The water-absorbing layer made in this way is a kind of “automobile diaper” (auto-diaper).

As you know, a superabsorbent (superabsorbent polymer, SAP, SAP) is a material that absorbs liquid in an amount many times higher than its own weight, and holds it inside. Thanks to these characteristics, superabsorbent is widely used in various fields of industry.

The vast majority of superabsorbents are made of sodium polyacrylate in the form of powder or granules. Some superabsorbents are also available in fiber form.

The granular material is a polymer consisting of millions of identical particles of sodium acrylate forming a chain structure. These chains are then linked together to create a three-dimensional network. In the dry state, long polymer chains are folded. When the superabsorbent absorbs liquid, the chains unfold and the network expands. The liquid is retained in the resulting space in the molecular network, and the material forms a gel.

Numerous studies have confirmed that superabsorbent is a safe material and is widely used in various industries, for example, in mechanical engineering, medicine in the manufacture of sanitary and hygiene products, etc.

The use of superabsorbent in the design of reusable absorbent auto-pampers allows you to hold more fluid, preventing it from penetrating the bottom of the car interior, as well as absorb moisture that has fallen on the car floor from the outside, and hold it inside the auto-pampers. This increases the resource of the product and the multiplicity of its use.

Then there is a waterproof layer, which is a protective layer, made, for example, from a polyethylene or polypropylene film.

Next is the lower water-permeable layer, which is made in the same way as the upper water-permeable layer of polyester non-woven absorbent material, which protects the waterproof layer from the bottom from mechanical damage and additionally absorbs moisture that has fallen on the bottom.

This design of reusable absorbent auto-pampers provides a significant increase in the duration of operation of the product, preventing the penetration of moisture, salt, chemicals, oils and other petroleum products on the bottom of the passenger compartment, which have a destructive effect on the coating of the passenger compartment, which improves the environment and comfort in the passenger compartment.

The present invention has high performance characteristics, including high wear resistance, reusability and ease of manufacture.

This invention is not limited to its use in vehicles. Reusable absorbent auto pampers can be used in those areas of industry where it is necessary to eliminate excess moisture, sand, oil products and unauthorized liquids that damage the metal and coatings.
