Abstract
The invention discloses a plastic and wood composite floor and a production method thereof. The woof floor comprises a plastic core layer (1), a solid wood surface layer (2) arranged above the core layer (1) and a solid wood base layer (3) arranged below the core layer (1), wherein the core layer (1) is fixed with the surface layer (2) and the base layer (3) by adhesive. The production process of the wood floor comprises: preparing the surface layer; preparing the core layer; applying the adhesive; combining a blank; and preparing a finished product. The core layer of the wood floor can be made of renewable plastic; therefore, one hand, waste recycling is realized and valuable tree wood is saved, and on the other hand, the wood floor has the advantages of high moisture resistance, high waster resistance, high dimension stability, comfort footfeel, and the like.
Description
Technical field
The present invention relates to a kind of wood flooring and production method thereof, especially a kind of plastics compoiste wood floor and production method thereof.
Background technology
Along with rapid economic development, the progressively raising of living standards of the people, the consumption of timber further increases, and has caused the rise of the wooden product price of China, wooden floor and be that the multi-layer solid wood floor price of wooden skin climbs up and up with rare tree.In order to alleviate the imbalance between supply and demand of Solid Wood Flooring Markets, also in order to protect the rare tree of China, realize sustainable development, how with recyclable materials such as plastic applications in making wood flooring, become the task of top priority of numerous instantly wood flooring producer.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of plastics compoiste wood floor and production method thereof.The sandwich layer of the wood flooring of producing adopts reproducible plastic production, has realized the cyclic utilization of waste on the one hand, has protected rare tree, and the present invention has advantages such as moistureproof water resistance is superior, dimensional stability good, feel is comfortable on the other hand.
For solving the problems of the technologies described above, technical scheme of the present invention: a kind of plastics compoiste wood floor, constitute the sandwich layer that comprises plastic production, above this sandwich layer, be provided with the top layer of solid wood, this sandwich layer below is provided with the basic unit of solid wood, and sandwich layer is fixed together by bonding adhesive and top layer and basic unit.
In the above-mentioned plastics compoiste wood floor, described sandwich layer is fixed together by bonding adhesive and top layer and basic unit, bonding adhesive adopts white glue with vinyl stick, acrylonitrile-butadiene rubber stick, neoprene stick, polyurethane adhesive or epoxyn, the bonding adhesive that glueds joint between sandwich layer and top layer and sandwich layer and basic unit or adopt the combination of any two kinds of bonding adhesive.
In the aforesaid plastics compoiste wood floor, described bonding adhesive adopts white glue with vinyl stick, epoxyn or polyurethane adhesive.
In the aforesaid plastics compoiste wood floor, described bonding adhesive adopts epoxyn.
In the aforesaid plastics compoiste wood floor, described basic unit is common wood or fast growing wood; Common wood is toothed oak wood or birch, and fast growing wood is poplar or China fir.
In the aforesaid plastics compoiste wood floor, described top layer is the top layer that famous and precious wood flower pear wood, Door frame, ebony or beautiful santal are made.
In the aforesaid plastics compoiste wood floor, described sandwich layer adopts plastics polypropylene (PP), polybutene (PB), acrylonitrile/butadiene/styrene copolymer (ABS), acrylonitrile-styrene resin (AS), polyamide (PA) or Merlon (PC) to make.
In the aforesaid plastics compoiste wood floor, described sandwich layer adopts plastics polypropylene (PP) or polybutene (PB) to make.
The production method of plastics compoiste wood floor comprises following production stage as described above;
Top layer to needed stock board is hacked with timber in a, preparation top layer;
B, preparation sandwich layer adopt plastics to make the sandwich layer of needed stock board;
C, gluing are carried out two-sided applying glue stick with sandwich layer, and the resin added of each face is 150～300g/cm
2
D, assembly are bonded together sandwich layer and two top layers, put into that press is colded pressing or hot pressing again, make the floor blank;
E, preparation finished product, with the floor blank slot, sanding, japanning, make finished product.
The production method of above-mentioned plastics compoiste wood floor is put into press and is colded pressing described in the steps d, the time of colding pressing is: epoxyn 0.2～0.5h; Polyurethane adhesive 2～4h; Acrylonitrile-butadiene rubber stick or neoprene stick 2～4h; White glue with vinyl 8～12h; Described hot pressing, hot pressing temperature are 80～100 ℃.
Beneficial effect of the present invention: compared with prior art, sandwich layer of the present invention adopts plastics compactings such as reproducible polypropylene, polybutene to form, and has realized the cyclic utilization of waste, has saved rare tree timber.Eight kinds of bonding adhesive and preparation method of the present invention that the present invention adopts a large amount of experiment screenings to get, sandwich layer and solid wood top layer close adhesion that polypropylene or polybutene are made, make dimensional stability of the present invention good, safety firmly, solved in the making of plastics compoiste wood floor the biggest problem of timber and plastic bonding; Because sandwich layer adopts the plastics of polypropylene or polybutene to make, so the present invention not only has superior moistureproof water resistance, test factually, the expansion rate of 24h water sucting thickness only is 0.8%, and common composite floor board is 2%～10%, but also have outstanding MOR, and to test factually, MOR is greater than 60MPa.
In order to make the good splicing of formation between timber and the plastics, selected for use 8 kinds of bonding adhesive to carry out contrast test, simultaneously polypropylene (PP), two kinds of base materials of polybutene (PB) have also been carried out comparative study, the main performance of investigating is bonding strength and dipping stripping performance.Result of the test is as shown in the table.
As can be seen from the test results, traditional timber " three urea formaldehydes " bonding adhesive, promptly urea-formaldehyde resin adhesive, synvaren and melamine resin adehsive are glutinous, are difficult in the good glue-joint strength of formation between timber and the plastics; Using the plastics compoiste wood floor glue performance of epoxyn preparation best, secondly is polyurethane adhesive, white glue with vinyl stick, and acrylonitrile-butadiene rubber stick and neoprene stick are minimum; The glue performance difference of PP plate and PB plate is little, and the PP plate is slightly quite a lot of.
