Description
Technical field
The invention belongs to building and ornament materials manufacture technology fields more particularly to a kind of for formaldehydeless environment-friendly wood floor
Film and preparation method thereof.
Background technology
Currently, the prior art commonly used in the trade is such：
The weatherability of traditional solid wooden floor board or solid wooden compound floor is poor, in the larger environment of humidity and temperature change
When used for a long time, deformation and cracking are easy tod produce.Existing compoiste wood floor is generally using density board containing formaldehyde and wearing layer, balance
Layer, the lamination of core fibre are glued and are formed.As the formaldehyde in the glutol of density plate adhesive, can slowly continue into air at normal temperatures
Ground volatilizees, and causes indoor formaldehyde content to increase substantially, can make one unconsciously be poisoned, the nose larynx excitement that goes out to lose face,
The symptoms such as eyes are shed tears, fatigue is weak, hypomnesia, headache, fever, asthma, hylactic pneumonia, dermatitis, this is i.e. so-called
" mansion syndrome " and " chemical substance allergy ".
In conclusion problem of the existing technology is：
(1) existing timber floor waterproof, dampproof effect are poor；
(2) contain formaldehyde, slow release, unhygienic environmental protection with the compound floor of glue.
The present invention can solve problem above, and old is produced using slicing wood chip and is significantly less than solid wooden floor board.
Solve the difficulty and meaning of above-mentioned technical problem：
The key for solving the above technical problem is film, it is desirable that film has certain rigidity and intensity, is different from glue, also
It is required that film has good bonding force, film that can be melted into entirety with wood chip stacking pressurized, heated with wood chip.So selecting
High density polyethylene (HDPE) (HDPE) is main material, HDPE good film-forming properties, waterproof；It is poly- that a certain proportion of maleic anhydride grafting is added simultaneously
Ethylene and EVA provide the bonding force of film and wood chip；Suitable filler can provide timber floor density and reduce cost.It solves
Above-mentioned technical problem can obtain environmental protection, good weatherability, timber floor at low cost, be of great significance.
Invention content
In view of the problems of the existing technology, the present invention provides a kind of film for formaldehydeless environment-friendly wood floor and its
Preparation method.
The invention is realized in this way a kind of film for formaldehydeless environment-friendly wood floor is as mass fraction, by following
Group is grouped as：100 parts of HDPE, 1~15 part of EVA, 1~20 part of MA-PE (maleic anhydride grafted polyethylene) and filler 0~20
Part.
The HDPE melt index are 0.9, for forming a film, enduring with all one's will；The VAC contents of the EVA are 10~20%, for increasing
Add stickiness；The MA-PE acid values are 8~9, the bonding force for improving PE and wood chip.
Another object of the present invention is to provide a kind of preparation methods of the film for formaldehydeless environment-friendly wood floor, including
Following steps：
(1) mixing match is carried out according to the mass fraction of each component；
(2) formula mixture is made to be plasticized using extruder, 180~210 DEG C of plasticization temperature；
(3) bubble, 20~25 DEG C of air-cooling mouldings, traction, trimming, winding film forming are blow molded into.
It is utilized made from the film for formaldehydeless environment-friendly wood floor without first another object of the present invention is to provide a kind of
Aldehyde environment-friendly wood floor.
The preparation method of the formaldehydeless environment-friendly wood floor, includes the following steps：
(1) film and wood chip are stacked alternately, both ends are film；
(2) 250~400 DEG C are heated through press, pressurize 1~15MPa, and film is made to merge into an organic whole with wood chip, is formed certain thick
Spend the waterproof of 7~20mm, insect prevention, without glue, timber floor formaldehydeless, free from extraneous odour is environmentally friendly.
In conclusion advantages of the present invention and good effect are：
HDPE is a kind of thermoplastic polyolefin generated by ethylene copolymer, is white powder or granular product, nontoxic, nothing
Taste, crystallinity are 80%~90%, and softening point is 125~135 DEG C, and temperature in use is up to 100 DEG C；Tensile strength and creep properties are excellent
In low density polyethylene (LDPE)；Wearability, electrical insulating property, toughness and cold resistance are preferable；Chemical stability is good, at ambient temperature, no
It is dissolved in any organic solvent, the corrosion of acid and alkali resistance and various salts is conducive to that film forming is stiffening, and the VAC contents of EVA are 10~
20%, the transparency is good, and resist cold stress crack resistant, has good adhesion；Present invention process is simple, provides through the invention
The film for formaldehydeless environment-friendly wood floor waterproof, insect prevention can be made, without glue, timber floor formaldehydeless, free from extraneous odour is environmentally friendly.
And the present invention is laminated using the film especially prepared with wood chip, pressurization, bonding is integrally formed, and the timber floor made is free of any first
Aldehyde does not have the generation of low molecular weight volatile object, so hygienic environment-protecting is safe, simultaneously because the water resistance of film, timber floor are weather-proof
Property greatly improves；Strong with wood chip bonding force due to the special formulation of film, timber floor is not easy to deform cracking；It is good using rigidity
High density polyethylene (HDPE) be main raw materials in producing films, obtained timber floor is rigidly good；It is original that wood chip, which can use the wood chip of slicing,
Material, reduces cost, obtains effect identical with solid wooden floor board, but also waterproof.
The glue of the film alternative composite plate of the present invention, forever without low molecular weight volatiles objects such as formaldehyde.Film have every
Water effect so that timber floor has good weatherability.The timber floor that the present invention obtains has following difference compared with existing floor：
| Solid wooden floor board | Plywood floor | This programme floor | |
| Expansion rate of water absorption % | 2.3 | 5.0 | 0.1 |
| Taste | Free from extraneous odour | Formaldehyde taste is dense | It is tasteless |
| Formaldehyde mg/100g | ≤9 | ≤40 | 0 |
| Density g/cm3 | 0.94 | 0.92 | 0.95 |
