Description

A kind of double-layer combined floor
Technical field
The present invention relates to a kind of floors, more specifically to a kind of double-layer combined floor.
Background technique
Currently, Compossite solid-wood floor plate mainly with multi-layer solid wood it is compound based on, performance is closer to pure solid wood with three layers.Three Layer solid wooden compound floor is staggeredly to be composed of three layers of thin solid wood board by more complex technique.Three layers of compound tense, compared with Thin bottom and surface layer wood grain is longitudinal arrangement, and thicker middle layer wood grain is transversely arranged, to neutralize the natural deformation of timber. The superficial layer of this three-layer wood composite flooring using good timber, (such as: want, remote redwood is wanted, mountain core by oak, maple, teak Peach and walnut etc.), middle layer, bottom then use elastic preferable fast growing wood (such as: pine, poplar), can efficiently solve A series of problems, such as timber floor changes the buckling deformation generated and cracking due to temperature and humidity in different environments.Three-layer real-wood The precious timber of composite floor board superficial layer not only remains solid wooden floor board wood grain grace, natural characteristic, and utmostly saves The about resource of high-quality precious timber, and be able to satisfy people and precious timber is liked.But existing MULTILAYER COMPOSITE solid wood Plate is still required to consume a large amount of timber, and with increasingly rare and protection environment the needs of timber resources, existing multilayer is multiple It closes solid wooden floor board and often faces the problem of production cost rises and destroys ecological environment.
In recent years, the US Department of Commerce discloses " double anti-" policy of U.S.'s multi-layer wooden floor anti-dumping to China, anti-subsidy, such as On November 12 2010 Washington, DC time, it is anti-that U.S. Department of Commerce announces U.S. multi-layer wooden floor product initiation anti-dumping defeated to China Subsidy merges investigation and determines.U.S. domestic industry is required on October 21st, 2010 to U.S. Department of Commerce and International Trade Commission application Anti-dumping anti-subsidy is carried out to multi-layer wooden floor product native to China and merges investigation.It is announced, is investigated according to U.S. Department of Commerce Product is three layers and three layers and combines the multi-layer wooden floor formed with upper layer and sandwich layer.In order to evade U.S.'s multi-layer wooden floor to China " double anti-" policy, some floor production enterprises in China expect that production only has the compoiste wood floor of double-layer structure, due to two layers The compoiste wood floor of structure is not belonging to the product within the scope of U.S.'s multi-layer wooden floor to China " double anti-" policy, therefore double-layer structure Compoiste wood floor is when exporting the U.S. with very big competitive advantage.But answering for double-layer structure is found in existing development process Closing timber floor, often manufacture difficulty is higher, and is easy to produce and comes unglued and deform.
The compoiste wood floor of double-layer structure, such as Chinese Patent Application No. are had been developed that in the prior art: 2006201259419, the applying date: on November 30th, 2006, invention and created name are as follows: a kind of solid wooden compound floor, this application A kind of solid wooden compound floor is disclosed, it includes dash board and substrate double-layer structure, and substrate uses finger-jointed plate, in substrate and dash board Flexible balance bar groove is provided on upper faying face.Flexible balance bar groove is 3~6 rectangles opened up along the length direction of plate Slot.It is equipped with and the staggered lower flexible balance bar groove of flexible balance bar groove on faying face thereon in base lower surface.Due to Substrate uses cold spelling finger-jointed plate, and substrate is compound using powerful white latex with dash board, is green so being entirely free of formaldehyde composition Environment-friendly products;Flexible balance bar groove reduces the internal stress of plate, in the case where dampness, heated or dry, deflection It is small, reduce the possibility that floor cripling occurs, cracks.But there is also the following defects for being difficult to overcome for this application: (1), being somebody's turn to do Solid wooden compound floor uses solid wood to manufacture completely, and high production cost and destruction ecological environment do not meet the principle of sustainable development; (2), the bonding force between dash board and substrate is smaller, is easy to appear phenomenon of coming unglued.
In conclusion how overcoming the compoiste wood floor high production cost of existing double-layer structure, destroying ecological environment, and hold It is also easy to produce the deficiency come unglued with metaboly, is the technical problem of urgent need to resolve in the prior art.
Summary of the invention
1. technical problems to be solved by the inivention
