Abstract

The present invention is made of three layers of wood materials, wherein an upper layer and a lower layer are medium density fibreboards, a solid wood core sheet is clamped between the upper layer and the lower layer, and the medium density fibreboards of the upper layer and the lower layer and the medium solid wood core sheet are glued by nontoxic white glue. The present invention has a manufacturing technique that the sanding treatment and the smoothing treatment of the solid wood core sheet are carried out by a large-scale sanding machine; the nontoxic white glue is coated on gluey surfaces of the solid wood core sheet after sanding and smoothing and the medium density fibreboards by a large-scale spreading machine, and the solid wood core sheet and the medium density fibreboards are put in a press machine for being pressed within three minutes; 40 tons of pressure are pressed on the solid wood core sheet and the medium density fibreboards on the press machine within a temperature range of 0 DEG C to 10 DEG C for 20 hours; or 40 tons of pressure are pressed on the solid wood core sheet and the medium density fibreboards on the press machine within a temperature range of 25 DEG C to 35 DEG C for 12 hours; when at a medium temperature, the pressure time can be adjusted according to a suitable proportion and the temperature. The present invention has the advantages that the present invention can be used for decorating rooms and can not emit gas harmful to human bodies, the present invention is an environment protection type decorated board and has smooth board surfaces, and the present invention is suitable for various decorative design boards.

Description

Environment protection type composite decorative plate

Technical field

The present invention relates to a kind ofly to be used to build, the wood-based plate of interior decoration, particularly a kind of environment-friendly type composite decorating board that helps health.

Background technology

Existing wood-based plate forms with core-board and multi-layer sheet bonding, is the solid wood core in the middle of this type of sheet material, the reel skin is horizontal wood chip, and outermost layer is vertical wood chip, with urinating aldehyde glue as binding agent, through hot-forming, constitute five layers of glued board, this multilayer composite sheet has following problem:

1, harmful to health, the binding agent urine glue aldehyde because of it behind plate forming, can give out a large amount of pernicious gas formaldehyde.

2, consume a large amount of timber, because of the positive and negative surface layer of this five-ply board must use high-quality timber, one cubic metre of production board needs consume a large amount of forest reserves with 0.253 cubic metre in high-quality timber.

3, the scope of application is little, and this class sheet material generally can only and be fitted up with foundation engineering sheet material as furniture production.

4, adhesive fastness is poor, because multi-layered bonded, tack coat is many more, then sheet material flake or lamination many more, cause the sheet material out-of-flatness.

Summary of the invention

The present invention is made by three layers of wood materials, and upper and lower layer be a medium density fibre board (MDF), and being clipped between the upper and lower layer is the solid wood chip, and the medium density fibre board (MDF) of upper and lower layer bonds with nontoxic white glues with the solid wood chip of centre, and its production technology is:

A carries out sanding, smooth processing with the Large Sand ray machine to the solid wood chip.

B on the adhesive surface of sanding, smooth solid wood chip and medium density fibre board (MDF), coats nontoxic white glues with large-scale glue spreader, puts on the press in the clock time at three minutes and pressurizes.

C, in 0 ℃ of-10 ℃ of temperature range, pressurization is 40 tons on press, keeps 20 hours; Or in 25 ℃ of-35 ℃ of temperature ranges, pressurization is 40 tons on press, keeps 12 hours; When medium temperature, press said temperature, proper proportion adjustment pressing time.

The advantage of this environment protection type composite decorative plate is:

1, has environmental-protecting performance, sheet material of the present invention is used to decorate indoor, can not give out harmful gas, decorating indoor environment monitoring center of association through China detects, the content of formaldehyde of sheet material of the present invention is that 0.81mg/L (national standard is 1.5mg/L) detects through interior decoration quality monitoring station, Shanghai City, and the total volatile organic matter of the present invention is 0.0614mg/m ³(national normal value is＜=0.3mg/m ³), this shows that the present invention has the favorable environment protection energy.

2, saved a large amount of timber, existing wood-based plate, every cubic metre of production board need consume 0.253 cubic metre of high-quality timber, the present invention does not then need high-quality timber to make cladding material, to produce 12000 cubic metres of sheet materials per year, can be country every year and saves 3036 cubic metres of high-quality timber.

3, the scope of application is wide, and the composite plate that the present invention produces has solved that flake in the surface and the quality problems of layering, makes plate surface smooth, needs applicable to various structural designs.

Description of drawings

Accompanying drawing is the schematic perspective view of composite plate of the present invention.

The specific embodiment

As shown in drawings, the present invention is a three-layer composite board, and the centre is with solid wood chip 2, its upper and lower layer medium density fibre board (MDF) 1, through being cold-pressed into product, finished product thickness has 16mm, 18mm, 25mm, 30mm with nontoxic white glues, length have 243cm,, width has 121cm, is applicable to indoor various decoration.

Claims (2)

1, a kind of environment protection type composite decorative plate, its feature in: this decorative panel is made by three layers of wood materials, and upper and lower layer is a medium density fibre board (MDF), being clipped between the upper and lower layer is the solid wood chip, and the medium density fibre board (MDF) of upper and lower layer bonds with nontoxic white glues with middle solid wood chip.

2, a kind of environment protection type composite decorative plate manufacturing process is characterized in that:

A carries out sanding, smooth processing with the Large Sand ray machine to the solid wood chip.

B on the adhesive surface of sanding, smooth solid wood chip and medium density fibre board (MDF), coats nontoxic white glues with large-scale glue spreader, puts on the press in the clock time at three minutes and pressurizes.

C, in 0 ℃ of-10 ℃ of temperature range, pressurization is 40 tons on press, keeps 20 hours; Or in 25 ℃ of-35 ℃ of temperature ranges, pressurization is 40 tons on press, keeps 12 hours.
