Description

A kind of wood-plastic composite floor and preparation method thereof

Technical field

The present invention relates to a kind of floor, and in particular to a kind of wood-plastic composite floor and preparation method thereof.

Background technology

With the quickening and the improvement of people's living standards of social life rhythm, it is desirable to more healthy living environment, wood Product is more used for various places, is widely used especially as ground pavement product-floor.But various floors are present not Same advantage and disadvantage.The characteristics of solid wooden floor board has elegant nature, comfortable foot feeling, good heat insulating, but dimensional stability is not good enough, When environment is excessively moist or dries the problems such as easy arch camber, warpage or deformation;Solid wooden compound floor can preferably overcome solid wood The true shortcoming in floor, but it inevitably uses substantial amounts of glue in process of production, therefore asked in the presence of harmful substance release Topic;Reinforced composite floorboard and solid wood(It is compound)Floor is compared more high-wear resistance, but its water resistance is poor.Three of the above floor Used as usage amount maximum floor, its common drawback is the presence of poor ageing-resistant performance and water resistance.Can not be in harsh conditions Lower application.Wood plastic composite is the sheet material that wood powder passes through certain process combining with plastics, and it has preferable water resistance Energy.Charing veneer is processed under the conditions of different medium controls 180 ~ 220 DEG C, and the sheet material after its charing has excellent anti- Rotten and dimensional stability.Wood plastic composite has significant economic, ecological and social benefit, but direct in long-term use Exposure in the sun and due to processing method, formula components and envirment factor etc. influence, wood plastic composite can occur it is aging, Under sustained stress effect, the deformation of creep can be produced, or even braking effect service life occurs.Utility model patent A kind of outdoor floorings of CN202969841U and a kind of wood-plastic composite floors of CN201343852Y, to carbonize veneer as floor surface Material, it is by adhesive that veneer is glued together with wood moulding base material.And base material is one side clad can.Both approaches due to There is harmful substance release in practical adhesive, simultaneously because base material one side facing has unequal power distribution phenomenon, be susceptible to stick up Qu Xianxiang.

The content of the invention

The present invention seeks to overcome what existing solid wooden compound floor was discharged using a large amount of natural precious timbers and harmful substance A kind of defect, there is provided dimensionally stable, unharmful substance release, floor texture and quality are good, and take into account saving timber resources simultaneously With there is solid wooden floor board surface effect, can be widely used for the wood-plastic composite floor of indoor and outdoor.And provide scientific and reasonable, easily In the manufacture method of the wood-plastic composite floor of shaping.

Realizing the technical scheme that the object of the invention is used is, a kind of wood-plastic composite floor, it is characterized in that, it includes:From upper It is combined by top finishing layer, upper table flaggy, upper dash board modified layer, intermediate layer, lower dash board modified layer and following table flaggy successively under Composition.

A kind of manufacture method of wood-plastic composite floor, it is characterized in that, it has including in:

1)Upper table flaggy, following table layer structure are identical, and using the veneer of any seeds of slicing, rotary-cut and sawing, it is thick It is 2 ~ 8 millimeters to spend, and in 180 ~ 220 DEG C of temperature, humidity 100%, carries out charing process at 1 ~ 4 hour retention time;

2)Dash board modified layer is covered with paint, lacquer, colour wash, etc. in the lower surface of upper table flaggy, dash board changes under being covered with paint, lacquer, colour wash, etc. on the upper surface of following table flaggy Property layer, upper dash board modified layer, lower dash board modified layer structure be identical, by silane coupler 40g/m2With plastic grain 60g/m2, Or methylene polyisocyanates 40g/m2With plastic grain 60g/m2, by hot press:180 ~ 190 DEG C of temperature, pressure 0.2MPa, 10 minutes time, the lower surface and upper dash board modified layer for making upper table flaggy are combined, the upper surface of following table flaggy is modified with lower dash board Layer is compound;

3)Intermediate layer is the mixture of plastic grain and wood powder, and its mass parts is 10 parts of plastic grain, 3 ~ 7 parts of wood powder, or It is the reclaimed materials of wood plastic composite;

4)Intermediate layer is placed between the modified layer that the modified layer and following table flaggy that upper table flaggy is combined are combined, using hot pressing Machine, 185 DEG C of temperature, pressure 2.5MPa, 25 minutes time, one step press is integral;

5)In step 4)Basis on, using tongue-and-groove equipment, groove is outputed in the side in intermediate layer, in the another of intermediate layer Output tenon in side;

6)In step 5)Basis on, in the upper surface coating surface coatings of upper table flaggy, top finishing layer is resistance to Paint is covered with paint, lacquer, colour wash, etc. on the paraffin of 95 ~ 340 DEG C of temperature or floor, is made finished product.

The plastic grain is at least one of polypropylene, polyethylene, polyvinyl chloride and high density polyethylene (HDPE).

The mesh number of the wood powder is 20 ~ 240 mesh, and moisture content is 2% ~ 10%.

The floor cover with paint, lacquer, colour wash, etc. paint for polyurethane paint, unsaturated polyester varnish, nitrate paint or, ultraviolet-cured paint.

Wood-plastic composite floor of the invention, to carbonize, dash board surface is modified to be combined with intermediate layer, improves wood plastics composite The dicoration on material surface, and through the veneer after charing process, its good stability of the dimension, aberration are small, and timber utilization rate is high.The present invention 18mm thick wood-plastic composite floor, boils through water(Leaching)Bending resistance load reaches 1240N after-frost-dried process, dipping and stripping rate 0, Wet method coefficient of friction is 0.7;Saving timber resources can simultaneously be taken into account and there is solid wooden floor board surface effect, do not had Evil substance release, can be widely used for indoor and outdoor.Its manufacture method is scientific and reasonable, it is easy to be molded.
