Description

A kind of high elasticity reinforced composite floor

technical field

The utility model relates to the field of decorative materials, in particular to a high-elastic reinforced composite floor.

Background technique

Laminate flooring is generally composed of four layers of materials, namely wear-resistant layer, decorative layer, high-density substrate layer and balance layer, also known as impregnated paper laminated wood flooring, laminated wood flooring, which is stronger than solid wood flooring High and has better moisture resistance and dimensional stability, but its elasticity is low and the foot feel is poor; cork mainly grows in the Mediterranean coast and the cork oak in the Qinling area of my country at the same latitude, and the raw material of cork products is cork oak Compared with solid wood flooring, it is more environmentally friendly, and has better sound insulation and moisture resistance, giving people an excellent foot feel, but cork flooring cannot be loaded for a long time, otherwise it will cause permanent deformation of the board surface, and Most of the cork floors are directly glued and pressed together with cork. The surface is relatively rough and has grooves, so it is easier to store dust and difficult to clean. Therefore, replacing the base layer of ordinary laminate flooring with a composite material of medium-density or high-density fiberboard and cork can improve the hardness and flatness of the floor surface, make the decorative texture more diverse, and improve the elasticity and shock resistance of the floor. , so that it has a better foot feel.

Utility model content

The purpose of the utility model is to propose a high-elastic reinforced composite floor with better surface performance and shockproof performance aiming at the current technical status of reinforced floor and cork floor.

In order to achieve the above purpose, the utility model adopts the following technical solutions: the high elastic reinforced composite floor is composed of a wear-resistant layer, a decorative layer, an upper substrate layer, a cork layer, a lower substrate layer and a balance layer, the decorative layer, the upper substrate layer Water-based polyurethane adhesive is applied between the cork layer, the lower substrate layer and the balance layer, wherein the wear-resistant layer is a wear-resistant impregnated paper made of base paper impregnated with aluminum oxide and melamine resin; the decorative layer It is an artificial veneer with beautiful texture and various textures; the balance layer is PVC board, and the above-mentioned layers are formed into a highly elastic reinforced composite floor with shock resistance after forming blanks and hot pressing.

The thickness of the wear-resistant layer is 0.4-1.0mm.

The thickness of the decorative layer is 0.4-1.0mm, and the water content is 6%-8%.

The upper substrate layer and the lower substrate layer are high-density or medium-density fiberboards made of poplar or eucalyptus, with a thickness of 3-4mm and a moisture content of 6%-8%; the cork layer is made of cork oak The bark is processed, its thickness is 1-3mm, and its moisture content is 6-8%. The total thickness of the composite substrate layer made of three layers is 8-10mm.

The thickness of the balance layer is 0.6-1.0mm.

The base material made of the upper base material layer, the cork layer and the lower base material layer is provided with a groove or tenon connected with the adjacent floor in the form of a flat buckle. The width of the groove is 3-4mm, and the groove does not contain Cork, the thickness of the tenon is 3-4mm, and the processing of the tenon does not involve cork, that is, the middle layer of the tenon is cork, and there are 0.8-1.2mm thick fiberboards on each side.

The beneficial effects of the utility model are: reasonable structure, convenient installation, good decoration and dimensional stability, good surface performance, elasticity and shock absorption performance, excellent moisture-proof performance and thermal insulation performance, and can be widely used in ordinary houses, kindergartens and Gym and other places.
