The utility model has an advantage of avoiding the harm caused by released formaldehyde of ordinary solid compound wood-floor to environment and human body.

Description

A kind of formaldehyde-free solid wood composite floor board
Technical field
The utility model relates to a kind of formaldehyde-free solid wood composite floor board.
Background technology
Solid wooden compound floor is that the sheet that forms with the wood single-plate gummed is a base material, is plane materiel with high-grade decorative veneer, forms floor sheet material by hot-pressing gluing technology; This sheet material through tailoring, operations such as mortise fluting and leaching paint curing are final forms a kind of indoor floor.Solid wooden compound floor is a kind of modern pavement, is mainly used in aspects such as indoor decorating, is one of the important wooden finishing material in current building and house decoration field.
The bonding adhesive that solid wooden compound floor product in the market uses mainly is the bonding adhesive that contains the formaldehyde composition, adds the problem of glue quality control, and product has a large amount of free formaldehydes release causing environment pollutions in production and use.Therefore, comprise that the room air pollution that the formaldehyde of the various ornament materials of solid wooden compound floor discharge to cause has caused people's great attention.The World Health Organization announces in " World Health Report in 2002 ", clearly room air pollution is classified as one of ten big factors that threaten human health, and on June 5th, 2004, the World Health Organization issued bulletin No. 153, announces that formaldehyde is strong carcinogenic substance.
Various in addition waste plastics can produce white pollution problems to a certain extent as not recycling energetically, are great harm to society.
The utility model content
The purpose of this utility model provides a kind of novel nontoxic eco-friendly formaldehyde-free solid wood composite floor board, solves the murder by poisoning problem of the free formaldehyde release of common solid wooden compound floor to environment and human body.
For achieving the above object, the utility model is taked following design scheme:
A kind of formaldehyde-free solid wood composite floor board, it is the solid wooden compound floor by backing material plate is cut out through thermocompression forming with after repairing again, mortise is slotted, leaching paint curing makes, described backing material plate is the wood single-plate more than two layers and overlays on decorative veneer flaggy on its surface course and cover mutually and constitute, between each wood single-plate for not containing the plastics or the plastic cement rete of formaldehyde; Between veneer and crossbanding plastic cement rete or the no-formaldehyde adhesive layer that does not contain formaldehyde.
Described plastics or the recovery plastics that do not contain formaldehyde are that thermoplastic reaches the plastic alloy of being made by two or more plastics melting mixing.
Described thermoplastic is polyethylene or polypropylene, polyvinyl chloride, polystyrene, 100~200 ℃ of its melt temperatures.
Described no-formaldehyde adhesive layer is a kind of in PE modified polyvinyl acetate glue stick EVA, PIC bonding adhesive MDI, modified starch series bonding adhesive, improved plant or the animal protein class adhesive layer.
Described wood single-plate can be poplar, birch, China fir, various pine, and the thin plate that forms through rotary-cut or slicing of other pin broad-leaved woods.
Described crossbanding can be the thin plate that is formed through rotary-cut or slicing by high-grade broad-leaved woods such as beech, teak, Manchurian ash, maple wood, linden, birch, toothed oak wood, black walnut, nanmu, camphorwood, red sandalwood, Hua Li.
Described sheet material be by plastics or reclaim glued membrane that plastics make and the wood single-plate assembly after hot pressing be bonded formaldehydeless veneer, wherein between base material and the face vener both can with the plastics glued membrane is bonding also can be bonding with the bonding adhesive that does not contain formaldehydes.
Described plastics are thermoplastic, plastic alloy and goods thereof fresh or that reclaim.Wherein thermoplastic can merge the plastic alloy of formation mutually for polyethylene or polypropylene, polyvinyl chloride, polystyrene and they.
The described formaldehydes bonding adhesive that do not contain is a kind of in PE modified polyvinyl acetate glue stick EVA, PIC bonding adhesive MDI, modified starch series bonding adhesive, improved plant or the animal protein class bonding adhesive.
The macromolecular material that the utility model selects for use unharmful substance to overflow---promptly adopt the plastics and the wood single-plate combination that do not contain formaldehyde to join the backing material plate that base forms, backing material plate again by the plastics glued membrane or do not contain the formaldehydes bonding adhesive and crossbanding bonding for eco-friendly formaldehydeless veneer, and then solidify to form formaldehyde-free solid wood composite floor board product by sheet material cutting, mortise fluting, leaching paint; Solved the murder by poisoning problem of common solid wooden compound floor free formaldehyde release now to environment and human body.
The utility model has the advantages that:
1. such solid wooden compound floor does not exist free formaldehyde to discharge, and has thoroughly solved to perplex the harm problem of formaldehyde to environment and human body of dissociating in solid wooden compound floor production and the use for many years always.
2. the physical and mechanical property of such solid wooden compound floor reaches the corresponding index of national Decorative veneered woodbased panel II class plate: 60 ℃ of water loggings 3 hours, under 3 hours the condition of 60 ℃ of oven dryings, the dipping strip length of each glue-line of sheet material was below 25mm; Other physical and mechanical properties also reach GB GB/T15104-2006 set quota.
3. such plastic cement pleurodiaphragmatic in terspace material of decorating with veneer mainly adopts the recovery plastics, in the wound considerable economic, also can alleviate the white pollution of waste plastic to a certain extent.
Description of drawings
Fig. 1 is the utility model formaldehyde-free solid wood composite floor board structural representation
The specific embodiment
As shown in Figure 1, formaldehyde-free solid wood composite floor board of the present utility model is the solid wooden compound floor by backing material plate 1 is cut out through thermocompression forming with after repairing again, mortise is slotted, leaching paint curing makes.
Described backing material plate 1 is for the above wood single-plate 101 of one deck (the wood single-plate lines of adjoining course intersect layings that interlace) up and down and overlay on a decorative veneer flaggy 102 on its surface course and cover mutually and constitute, between each wood single-plate and between wood single-plate and crossbanding for covering layers 103.
The layer that covers between described each wood single-plate is not contain the fresh charge of plastic of formaldehyde or reclaim the plastic cement rete; Cover layer for the fresh charge of plastic that do not contain formaldehyde or reclaim a kind of in plastic cement rete, the no-formaldehyde adhesive layer between wood single-plate and crossbanding.
