Abstract
The invention discloses an aldehyde-free consolidated composite floor and a manufacturing method thereof. The aldehyde-free consolidated composite floor comprises an HDF density board, decoration wood grain paper and balance paper, wherein the decoration wood grain paper is arranged on the upper surface of the HDF density board; the balance paper is arranged on the lower surface of the HDF density board; the HDF density board is a density board which is produced by isocyanate formaldehyde component-free bonding resin; the decoration wood grain paper is a decoration wood grain PP (Propene Polymer) film which is produced by formaldehyde component-free resin; and the balance paper is an aldehyde component-free resin adhesive PE (polyethylene) film.
Description
Technical field
The present invention relates to
a kind of non-formaldehyde intensified composite floor board and preparation method thereof.
Background technology
We know, existing strengthening composite floor be by HDF density board, impregnated melamine glue woodgrained paper, dipping abrasion-proof paper, dipping balance paper assembly through high temperature, high pressure, hack, open the post-production techniques such as tongue and groove and form.
In prior art, reinforced composite wooden floor cannot be accomplished to add without aldehyde, be because " density board, woodgrained paper, balance paper " use binder resin, in impregnating resin all containing formaldehyde composition, and indispensable.Have not yet to see and do not apply in above-mentioned material containing the binder resin of formaldehyde and impregnating resin.This just makes reinforced composite wooden floor cannot accomplish without the manufacture of aldehyde adding technology, and product is also just containing formaldehyde composition.Although prior art can make the Form aldehyde release norm controlling of product exist
country is strongin standard processed, but trace formaldehyde is still had to discharge, and decades-long, cause domestic environment to pollute, meanwhile, the processing of above-mentioned material assembly must adopt uniform temperature, pressure just can complete manufacture technics, causes the pollution to environment.
Documents 1, Chinese patent 201220567855.9 discloses a kind of wood floors adopted without aldehyde radical material, it comprises the basic unit and the surface layer being positioned at basic unit's upper and lower surface that are made up of multiple wooden floor layer and the adhesive layer that is positioned at wooden floor interlayer between two and bottom, described surface layer are provided with wearing layer, described basic unit is provided with tongue-and-groove and joint tongue, it is characterized in that, the adhesive of described adhesive layer is bio-based soybean protein glue.This
inventionbeneficial effect be: with biological soybean protein glue for gummed raw material, realize without aldehyde production, environmental protection.
Documents 2, Chinese patent 201410353344.0 discloses the indoor veneer of the formaldehydeless gummed of a kind of high stability or the manufacture method of floor base material, comprises following processing step: 1) veneer drying; 2) spread on veneer surface or spray surface modifier, being dried to veneer surface filming; 3) veneer is arranged, assembly on request, the hot melt adhesive film that between every two-layer veneer, laying one is identical with veneer book size; 4) slab is sent into hot press hot-press gluing shaping, hot pressing terminates rear cooling, ejecting plate discharging; 5) slab normal temperature is deposited, and makes finished product through size and aftershaping machining.Advantage: use hot melt adhesive film to substitute traditional formaldehyde system bonding adhesive, the release of product formaldehydeless or other hazardous substances, saves coating process, improves production environment, enhances productivity; Veneer surface adopts the waterproofing agent of organosilicon modification of environment-friendly type, makes veneer case hardness increase and form hydrophobic film, greatly improves the cementing strength of hot melt adhesive film and base material, improves product water proofing property and dimensional stability.
Documents 1 and documents 2 are without aldehyde floor, but documents 1 not mentioned preparation method, documents 2 have employed hot press, employs HTHP.
Summary of the invention
The technical problem to be solved in the present invention is to provide
a kind of non-formaldehyde intensified composite floor board and preparation method thereof.
The present invention is achieved through the following technical solutions:
A kind of non-formaldehyde intensified composite floor board, comprise HDF density board, be arranged on the decoration woodgrained paper of HDF density board upper surface, be arranged on the balance paper of HDF density board soffit, described HDF density board is the density board using the formaldehydeless composition binder resin of isocyanates to produce, described decoration woodgrained paper is the decoration wood grain PP film that formaldehydeless composition resin makes, and described balance paper is without aldehyde composition resin glue PE film.
A kind of non-formaldehyde intensified composite floor board preparation method, with HDF density board for base material, apply without aldehyde composition binder resin at substrate surface, polyurethane-modified coating adopts roller line pressure combination process will decorate woodgrained paper and HDF density board bonds, adopt roller line pressure combination process balance paper and HDF density board to be bonded in the coating of base material bottom surface without aldehyde composition binder resin, polyurethane-modified coating.
Further, described HDF density board is the density board using the formaldehydeless composition binder resin of isocyanates to produce, and described decoration woodgrained paper is the decoration wood grain PP film that formaldehydeless composition resin makes, and described balance paper is without aldehyde composition resin glue PE film.
Compared with prior art, the present invention thoroughly solves reinforced composite wooden floor containing aldehyde component problem, and does not use high-temperature high-pressure craft in manufacturing process, sheet material does not produce new stress, thus can enter lower road formed machining without the need to health, great environmental protect, meets consumer demand.
Detailed description of the invention
Below in conjunction with embodiment, the invention will be further described:
A kind of non-formaldehyde intensified composite floor board preparation method, with HDF density board for base material, apply without aldehyde composition binder resin at substrate surface, polyurethane-modified coating adopts roller line pressure combination process will decorate woodgrained paper and HDF density board bonds, adopt roller line pressure combination process balance paper and HDF density board to be bonded in the coating of base material bottom surface without aldehyde composition binder resin, polyurethane-modified coating.
Described HDF density board is the density board using the formaldehydeless composition binder resin of isocyanates to produce, and described decoration woodgrained paper is the decoration wood grain PP film that formaldehydeless composition resin makes, and described balance paper is without aldehyde composition resin glue PE film.
Above-described embodiment, only for technical conceive of the present invention and feature are described, its object is to person skilled in the art can be understood content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed within protection scope of the present invention.
