Abstract

The present invention relates to a method for directly melting composite thermoplastic films on the surface of a wood plate. The method comprises the steps that firstly, needle holes are densely distributed on the surface of the wood plate, and then, films are paved; a stainless steel plate is covered, heating and pressurization are carried out on a thermocompressor, so that the plastic films are melted so as to enter the needle holes and be tightly matched with the needle holes, and the films are locked on the surface of the wood plate; the surfaces of the films also form required surfaces under the expression of the stainless steel plate.

Description

A kind of method at wood plank surface fusing thermoplastic plastic film

(1) technical field:

The present invention relates to a kind of method at the direct fusion composite thermoplastic plastics in wood plank surface (polyvinyl chloride, polyethylene, polypropylene wait a moment together) film.

(2) background technology:

No matter wood plank surface pad pasting is than japanning economy, durability, still aspect such as the feature of environmental protection all has tangible advantage, only sees have but have now in the method for the surperficial pad pasting of wood plank: 1. at wood plank surface brush coating liquid adhesive, stick film (or paper) then; 2. the paper that is soaked with thermosetting resin, be attached on the wood plank surface with the method that heats, pressurize.The goods that directly are affixed on the wood plank surface as for the thermoplastic film yet there are no commercially available, and its relevant technology also yet there are no report.

(3) summary of the invention:

Task of the present invention provides and a kind of the direct fusion of thermoplastic film is compound in the wood plank surface, simple, the easy method of row.

Task of the present invention is finished like this: at first prick the cloth pin hole thick and fast on the wood plank surface, spread the film that will paste then, cover the corrosion resistant plate of certain fineness on the film again, lie on the hot press and heat, pressurization, make the plastic sheeting fusing, and enter pin hole, and the film surface also forms required surface under the corrosion resistant plate extruding, reach film and be firmly fixed at the wood plank surface, and obtain required film outward appearance.

The present invention compares difference with existing method for adhering film to be had respectively: can save adhesive; It is good to use physical and chemical performance, inexpensive thermoplastic; And because the plastics of fusion enter pin hole, closely cooperate, can obtain the bond strength of comparatively ideal film and wood plank to the locking of the film on wood plank surface with pin hole; Can select transparent plastic film material for use,, can see the natural grain of wood, satisfy the pursuit of modern the authenticity aesthetic feeling by film; And can in wood plank is shaped processing, finish multiple membrane process simultaneously, save production cost.

(4) description of drawings:

Particular content of the present invention further specifies as follows in conjunction with the accompanying drawings:

Figure is my the patent application application number that " is furnished with the glued board of pin hole on the wood chip ": the wood chip schematic diagram of 200410011645.1 superficial layers, the figure cutting plane is vertical with the wood plank surface.

Fig. 1: (1) wood plank superficial layer wood chip

(2) pin hole, be blind hole, be used for multiple film, aperture 0.3mm-0.4mm, hole depth 0.5mm-0.6mm, pitch-row 2mm * 2mm, hole and wood plank surface is vertical.

(3) pin hole is used between layer of plywood gluing.

Fig. 2: (1) wood plank superficial layer wood chip.

(2) pin hole is a through hole, aperture 0.3mm-0.4mm, and pitch-row 2mm * 2mm, wood chip simultaneously are used between layer of plywood gluing, and one side is used for multiple film.

(situation appropriateness such as pinhole diameter, the degree of depth, the visual wood chip of distance are adjusted)

(5) specific embodiment:

The invention process process is as follows:

Wood plank adopts me preceding patent application " to be furnished with the glued board of pin hole on the wood chip ", gets size and is 60cm * 60cm, suppresses pin hole with draw point plate or porcupine roller machine earlier on wood plank superficial layer wood chip, as Fig. 1, Fig. 2.With the thick thermoplastic film of 0.1-0.2mm, with 0.5mm-1mm thick corrosion resistant plate, corrosion resistant plate and film contact-making surface are wanted smooth polishing, (but also frosted or other patterns).Plywood molding carries out simultaneously with multiple film.

Example 1, form glued board base group, spread film on its top layer pin hole face, cover corrosion resistant plate on the film, heat, pressurize as the wood chip of Fig. 1 and other wood chip.

Example 2, form glued board base group as the wood chip of Fig. 2 and other wood chip, its pin hole face upper berth, top layer film covers corrosion resistant plate, heats pressurization, note multiple identical with the tacky film of internal layer at the film on surface, in order to molten mutually, better locking multiple film.

In the enforcement, the principle of heating is that film melts fully, but does not have decomposition, and (with the polychloroethylene film heating-up temperature is about 180 ℃; With the polyethylene film heating-up temperature is about 170 ℃; With the polypropylene screen heating-up temperature is about 200 ℃); Pressurization will reach the plastics of fusion are pressed into pin hole, and pressure is about the 20-40 kg/cm, and remover will be gone up in the corrosion resistant plate surface, and as silicone oil etc., hot press can be with the hot press of system wood-based plate, if pressure is not enough, available method of dwindling product area solves.Compacting finishes, and is cooled to 60 ℃ of-80 ℃ of taking-ups, keeps flat deburring, finished product.

Claims

One kind on wood plank surface the direct method of fusion composite thermoplastic plastic sheeting, it comprises, at first at the intensive bundle cloth pin hole in wood plank surface, spread the thermoplastic film then, cover corrosion resistant plate on the film, make the plastic foil fusing and enter pin hole through heating, pressurization, closely cooperate with pin hole.
