Abstract

The utility model provides a wear-resistant composite wooden floorboard, which consists of a wear-resistant layer, a decorative layer, a substrate layer and a balance layer, wherein a high-density fiber board is superposed with a wood board to form the substrate layer, the upper surface of the high-density fiber board is contacted with the lower surface of the decorative layer, and the lower surface of the high-density fiber board is contacted with the upper surface of the wood board. On one hand, since the substrate layer formed by the high-density fiber board is stuck upon a single layer of wood board or multiple layers of wood boards and the wood board has a low water-swelling rate and cannot be easily damped to deform, the waterproofness of the floorboard is enhanced; on the other hand, since the wear-resistant layer and the decorative layer with pseudo-natural wood grains are attached on the upper surface of the high-density fiber board, the appearance of the floorboard is bright, the floorboard can resist wear, and moreover, the release of formaldehyde is effectively controlled.

Description

Wear-resisting compoiste wood floor

Technical field

The utility model relates to a kind of compoiste wood floor.

Background technology

Wood floors are widely used as the ground pavement material at repairs profession now.Along with the raising of people's living standard and the reinforcement of environmental consciousness, the Practical Performance and the feature of environmental protection of various finishing material in the finishing material are had higher requirement.Solid wooden compound floor that existing market is sold and laminated flooring are compared, and its pluses and minuses are respectively arranged.The central layer expansion rate of water absorption of solid wooden compound floor is lower, the strong and distortion of not worrying making moist of stability, and after the wooden skin coating of bonding preciousness paint is handled, elegance attractive in appearance, fine and smooth bright and clean, but the product cost height, market price costliness, paint a little less than the abrasion resistance on the surface.The variation of laminated flooring colour image, texture natural beauty, beautiful, wear-resisting, maintenance is simple and easy to arrange, relative price is cheap, but aspect expansion rate of water absorption and burst size of methanal, since the characteristic of selected base material high density fiberboard with and the limitation of production technology, be difficult to fundamentally solve because of the water proofing property difference and have a small amount of formaldehyde to discharge the negative issue that brings.

Therefore, provide a kind of novel floor product on existing floor that can replace in fact for necessary.

The utility model content

The utility model is at the deficiency of existing product, provides that a kind of surface is beautiful, wear-resisting, the wear-resisting compoiste wood floor of waterproof, environmental protection.

For achieving the above object, the utility model has adopted following technical scheme: a kind of wear-resisting compoiste wood floor is provided, comprises wearing layer, decorative layer, substrate layer and balance layer from top to bottom successively; Wherein, described substrate layer is formed by stacking by high density fiberboard and solid wood plate, and the upper surface of described high density fiberboard contacts with the soffit of described decorative layer, and the soffit of high density fiberboard contacts with the upper surface of described solid wood plate.

Described solid wood plate can be individual layer solid wood plate or multi-layer solid wood plate.

The upper surface of described high density fiberboard is distributed with crisscross groove, so that cut out plate.

Pass through the bonding stack of bonding adhesive between described high density fiberboard and the solid wood plate.

By above scheme as seen, wear-resisting compoiste wood floor of the present utility model, constitute substrate layer by bonding high density fiberboard above single or multiple lift solid wood plate on the one hand, utilize the water resistance that solid wood plate expansion rate of water absorption is little, characteristics not moisture-sensitive distortion promote flooring product; On the other hand wearing layer and the decorative laminate with imitative grain of natural wood are affixed on the upper surface of high density fiberboard, make its outward appearance beautiful, wear-resisting, and make burst size of methanal obtain better controlled.

The specific embodiment

Also the utility model will be further described in conjunction with the accompanying drawings below by embodiment.

Referring to illustrated in figures 1 and 2, the embodiment one of the wear-resisting compoiste wood floor of the utility model is overlayed by top-down wearing layer 1, decorative layer 2, substrate layer 3 and balance layer 4 and constitutes, and wherein substrate layer 3 is made of through the bonding stack of bonding adhesive high density fiberboard 5 and individual layer solid wood plate 6.The upper surface of high density fiberboard 5 contacts with the soffit of decorative layer 2, and the soffit of high density fiberboard 5 contacts with the upper surface of individual layer solid wood plate 6.The upper surface of high density fiberboard 5 is distributed with crisscross groove 7, so that cut out plate.

For embodiment shown in Figure 3 two, this wear-resisting compoiste wood floor is to be made of top-down wearing layer 1, decorative layer 2, substrate layer 30 and balance layer 4 equally, and substrate layer 30 is made of through the bonding stack of bonding adhesive high density fiberboard 5 and multi-layer solid wood plate 8.The upper surface of high density fiberboard 5 contacts with the soffit of decorative layer 2, and the soffit of high density fiberboard 5 contacts with the upper surface of multi-layer solid wood plate 8.The upper surface of high density fiberboard 5 is distributed with crisscross groove 7 equally.

The production stage of the wear-resisting compoiste wood floor of above-mentioned two kinds of embodiment is as follows:

1, utilizes one side coater that bonding adhesive is coated wherein one side of high density fiberboard equably, then utilize the artificial or mechanical one side that will be coated with bonding adhesive again, fully contact with the wherein one side of single or multiple lift solid wood plate; Insert the 1200T hot press, pressure transfers to 5MPa～15MPa, temperature is set to 140 ℃～200 ℃, time 30S～180S, treat that bonding adhesive solidifies fully after, plank withdraws from hot press, and to cool off health standby;

2, with professional wood routing machine, on the high-density plate face, mill out crisscross orthogonal vee-cut 7, mark off required ground board size;

3, adopt hot press, wearing layer 1, decorative layer 2 are overlayed the upper surface at high density fiberboard 5, and, make finished product floor as shown in Figure 4 and Figure 5 at last through cutting out plate, leaving tongue-and-groove 9 by heat pressing process.
