Abstract

The present invention relates to a bamboo wood injected and formed floor tile whose small bamboo wood pieces are provided with through holes. Through high-pressure injection molding, melted high molecular polyester injected into a die cavity enters gaps between holes and blocks of the small bamboo wood pieces and are quickly cooled, a plurality of assembled small bamboo wood pieces are mutually tensed, inserted, and wrapped together, high molecular polyester is covered at five surfaces of the assembled small bamboo wood pieces, and only the upper surface bares the bamboo wood. The floor tile can effectively prevent moisture, water and moth attack and can not buckle or deform. Because the present invention is not influenced by the temperature difference of four seasons, the present invention does not crack or loose, and sticking among blocks is firm.

Description

Bamboo and wooden floor brick and production technology thereof

The present invention relates to a kind of bamboo and wooden floor brick and production technology thereof.

Bamboo and wooden floor is cool in summer and warm in winter because of having, light is sliding, comfortable, the elegant and poised characteristics of step sense, and very popular, along with the raising of living standards of the people, it by many people as decorating room or or the floor in office, amusement place.But the present bamboo and wooden floor brick of laying is that bamboo timber is cut into a piece bamboo wooden unit, be spliced by various resin binder pressurization bondings or tongue and groove, because wood floor bolck moisture proof, water resistance are relatively poor, laying bamboo and wooden floor brick must contact moist influence to it with ground to be difficult to avoid, therefore the bamboo and wooden floor brick is subjected to four seasons temperature difference influence can produce the expansion contraction and causes buckling deformation, explosion, has shortened application life.In addition, its decay resistance is also relatively poor, subjects to damage by worms.

US Patent specification US-2466613 discloses a kind of detachable plated construction easily, in every floor panels, have the bolt through hole of a pair of lateral attitude, will very long bolt during laying floor passing every floor panels through hole connects together, because it is limited to be used to connect the elastic force of the bolton power on floor and spring, be connected closely between the piece that is difficult to guarantee wood floor bolck and the piece, produced by four seasons temperature difference influence to expand to shrink and cause buckling deformation.

The objective of the invention is to overcome the defective that above-mentioned existing bamboo and wooden floor brick exists, provide a kind of structure tight firmly, be not subjected to four seasons temperature difference influence and cause distortion, moistureproof, Corrosion Protection is good, hard smooth long-lived bamboo and wooden floor brick in surface and production technology thereof.

Bamboo and wooden floor brick provided by the present invention mainly is to utilize macromolecule polyester with the injection mo(u)lding of polylith bamboo wooden unit, its structure is to insert in the die cavity after the bamboo wooden unit that polylith has a through hole is spliced and combined, with the macromolecule polyester is that medium passes through the screw injection molding machine fusion in high pressure injects die cavity, make between the through hole of every bamboo wooden unit and piece and the piece and be marked with macromolecule polyester, polylith bamboo wooden unit is shunk tension mutually to be inlayed and is bundled together, make its five surfaces coat one deck macromolecule polyester, have only upper face to expose the woody body of bamboo.

Because wood floor bolck provided by the present invention is to utilize macromolecule polyester such as engineering plastics or polyvinyl chloride etc. with the injection mo(u)lding of polylith bamboo wooden unit, make its five surface parcel one deck macromolecule polyesters, have only the top table and expose the woody body of bamboo, therefore its structure is tight firmly, waterproof and dampproof performance is better, buckling deformation, explosion and the phenomenon that gets loose can not occur, and can prevent damaging by worms, corrosion-resistant, durable in use, install simple and convenient, quality good.Especially adopting bamboo matter is that the wood floor bolck intensity and the hardness of material is better, and the bamboo of its upper face is smooth smooth hard and present isabellinely, and third dimension is strong and attractive in appearance, can compare favourably with high-grade teak, redwood floor.

Reaching embodiment in conjunction with the accompanying drawings is described in detail the present invention.

Fig. 1-be oblique view of the present invention;

The sectional view of the bamboo wooden unit of Fig. 2-attempt 1.As shown in the figure, the present invention laterally has at least more than one through hole 2 at every bamboo wooden unit 1, has two through holes 2 in the present embodiment, and the inclined-plane is all dug in four sides of every bamboo wooden unit 1, and its gradient is 1 °.Insert in the die cavity after polylith being had the bamboo wooden unit splicing of through hole, with macromolecule polyester 3 as engineering plastics or polyethylene or polypropylene or polyvinyl chloride etc. be medium by the screw injection molding machine fusion in high pressure injects die cavity, make between the through hole 2 of every bamboo wooden unit 1 and piece and the piece and be marked with macromolecule polyester 3, thereby polylith bamboo wooden unit 1 is shunk tension mutually to be inlayed and is bundled together, bottom surface at wood floor bolck covers macromolecule polyester 3, the blank remainder that the 1-2 mm wide is reserved except that the first half in its four sides all covers macromolecule polyester 3, have only upper face to expose the woody body of bamboo, only see the natural true qualities of bamboo wood after brick and brick are stitched together like this.

The production technology of making this bamboo and wooden floor brick is a), the bamboo wood of handling well is processed into a piece bamboo wooden unit, all has through hole 2 in every bamboo wooden unit 1; B), put into baking oven then and make it dry; C) become plate to insert in the die cavity polylith bamboo wooden unit 1 composite assembly again, with macromolecule polyester 3 is that medium passes through the screw injection molding machine fusion in high pressure injects die cavity, make the macromolecule polyester of molten state get into the rapid cooled and solidified in slit between the through hole 2 of every bamboo wooden unit 1 and piece and the piece, polylith bamboo wooden unit 1 is shunk tension mutually to be inlayed and is bundled together, and, have only upper face to expose the woody body of bamboo at its five surface coverage one deck macromolecule polyesters 3; D) with the wood floor bolck depanning after the injection mo(u)lding, polish its upper surface; E), again wood floor bolck being carried out waxing polishing at last handles.
