Abstract
The invention relates to a formaldehyde free laminated wood board and multi layer real wood material manufacture. It is made by putting the veneer horizontally crossing, laying fuse glue film or thermal plastic film between veneers to form board sets, then hot forming, pressurizing, cooling to normal temperature to get the final product. Using fuse film or thermal plastic film, it replaces the formaldehyde free adhesive agent to prevent the stretch of the veneer due to the absorption of water to increase the stability of the laminated board size.
Description
Technical field
The present invention relates to the manufacture method of a kind of zero-formaldehyde plywood, zero formaldehyde multi-layer wood substrates.
Background technology
Prior art since oneth century, has been glued together glued board or the multi-layer wood substrates that forms, traditional glue applying method in manufacture process and employed synthetic adhesive by multilayer thin wood plate (abbreviation veneer) at present.Have following shortcoming: 1, the adhesive of common use is based on synthetic resin, as urine aldehyde glue, phenol glue, melamine glue etc.; These adhesive all contain the formaldehyde of harmful to human.2, traditional glue applying method is to use liquid adhesive, with the glue spreader of drum-type, with adhesive applicating on veneer.Because liquid adhesive applicating is behind the veneer of drying, veneer absorbs adhesive, and the flexible phenomenon of veneer can take place.When actual mechanical process, be difficult to grasp the extension degree of every veneer, often cause the defective that " sandwich " or " hollow " arranged between veneer and the veneer.And when veneer has applied after the liquid glue, can improve the moisture content of veneer, glued board, influence the glued board size stability, even the phenomenon that is distorted.
Summary of the invention
The objective of the invention is: the manufacture method that a kind of zero-formaldehyde plywood, zero formaldehyde multi-layer wood substrates are provided, it has not only overcome the defective that contains the formaldehyde of harmful to human in the prior art effectively, and prevented that veneer is because of suction, the veneer that causes is upheld, and has increased the glued board size stability.
The present invention is achieved in that the manufacture method of a kind of zero-formaldehyde plywood, zero formaldehyde multi-layer wood substrates may further comprise the steps:
(1) with veneer cross arrangement in length and breadth, lay does not contain the hot melt adhesive film or the thermoplastic film of formaldehyde between veneer and veneer, makes the plate group;
(2) the plate group is through hot-forming;
(3) under the pressurize condition, be cooled to room temperature, get product.
The plate group is at 8～28kg/cm described in the step (2)
2Under the condition of pressure, 80～280 ℃ of temperature, hot pressing moulding in 1～12 hour in hot-press arrangement.
Described step (2) comprise following 3 step by step:
1. between two bearing plates, according to bearing plate, plate group, heat-conducting plate ... plate group, overlapping the banking up of bearing plate order are made the hot pressing sheetpile, wherein have two laminate groups, one deck heat-conducting plate at least;
2. the hot pressing sheetpile is moved on on the end guide rail that sets in advance in the preformer, on the hot pressing sheetpile, place the top guide rail then, be forced into 8kg/cm
2～28kg/cm
2, with the top guide rail and end guide rail is removably fastening is linked together;
3. with hot pressing sheetpile and top guide rail, after guide rail integral body is taken off at the end, move into baker, under 80 ℃～280 ℃ temperature, heated 1 hour～12 hours; Described step (3) is: after being cooled to room temperature, remove top guide rail, end guide rail and heat-conducting plate, get product.
The manufacture method of a kind of zero-formaldehyde plywood of the present invention, zero formaldehyde multi-layer wood substrates, substitute the adhesive that contains the formaldehyde composition of the prior art with hot melt adhesive film or thermoplastic plastic membrane, prevented that veneer is because of absorbing the moisture in the liquid glue, and the extension phenomenon that causes has strengthened the glued board size stability.
