CZ20022937A3 - Joint of a floor covering with a solid substrate - Google Patents

Abstract

In the present invention, there is disclosed a joint of floor covering with a solid substrate such as wood, metal, plastic and the like, using a fusible pressure sensitive compound based on synthetic resins and ethylene-vinyl acetate, comprising more than 80 percent of the total volume of ethylene-vinyl acetate copolymer, up to 20 percent of aliphatic hydrocarbon resin and up to 5 percent paraffin wax of the total volume. The invented joint can be used in manufacture of means of conveyance, or in construction industry when building flats, offices, large shops and business objects. The fusible pressure sensitive compound based on synthetic resins and ethylene-vinyl acetate is declared suitable for use from both the health and environment point of view and is non-inflammable.

Description

Technical field

The invention relates to the connection of a floor covering to a solid substrate, e.g., wood, metal, plastic and the like.

BACKGROUND OF THE INVENTION

The known joints of the floor covering to a solid substrate employ many attachment methods, but gluing is most often required when bonding over the entire surface.

Either dispersion or solvent adhesives are used for such gluing and are applied in different ways to both or to one glued surface. In both cases, it is necessary to adhere to the prescribed minimum setting time after application of the adhesive.

At the end of this time, the two parts to be glued are placed on each other and loaded with a weight, or pressed in another way, for example with a roller, trowel or special tool. Another condition for a firm attachment of the glued parts with dispersion and solvent adhesives is to maintain the maximum setting time, because when the glue is exceeded, the adhesive dries and does not stick. Working with solvent adhesives contaminates the environment with harmful volatile substances, the disposal of which requires costly equipment to prevent environmental pollution.

SUMMARY OF THE INVENTION

The above-mentioned disadvantages are eliminated by the floor covering to the solid support according to the invention, consisting of the floor covering, the solid support and the bonding material, in that a pressure-sensitive hot-melt adhesive based on synthetic resins and ethylene vinyl acetate, copolymer composition ethylene-vinyl acetate more than 80% of the total volume, aliphatic hydrocarbon resins up to 20% and paraffin wax up to 5% of the total volume.This pressure-sensitive hotmelt adhesive based on synthetic resins and ethylene-vinyl acetate is harmless to health and environmentally friendly and non-flammable .

The method of joining a floor covering to a solid substrate is to apply a molten mass of 170 ° C to one or both surfaces to be bonded. The parts to be bonded can be bonded immediately, without a minimum setting time, but also after any time, as the pressure-sensitive hotmelt adhesive based on synthetic resins and ethylene-vinyl acetate remains permanently equally tacky. In order to ensure the strength of the joint, it is necessary to press the two parts to be joined together over their entire surface.

The advantage of using a pressure-sensitive hot-melt adhesive based on synthetic resins and ethylene-vinyl acetate is that the bonding of the floor covering to solid substrates is considerably accelerated, as well as the contamination of the working environment, eliminating the need for complex filtering equipment and costly operation.

Exemplary embodiments of the invention

The solid substrate is provided with a pressure-sensitive hot-melt adhesive on the upper side, based on synthetic resins and ethylene-vinyl acetate. The floor covering is also provided with the same pressure-sensitive fusible bonding layer over its entire surface. When the two parts are applied and pressed together, a strong connection is created which meets the requirements for heavy duty loads.

Industrial applicability

Joining the floor covering to a solid substrate using a pressure-sensitive hot melt adhesive based on synthetic resins and ethylene vinyl acetate can be used in all cases where the floor covering is installed on solid substrates, eg in vehicles, or in the construction industry for housing construction, offices, large halls and buildings for business.
