Abstract
The invention relates to a foreign-formaldehyde-free solid wood composite floor and a production technology. The production technology is characterized by comprising the following specific processes of: loading a back plate, heating the back plate, gluing the back plate, loading a core plate, assembling the core plate and the back plate, laminating the core plate and the back plate, primary gluing a laminated plate, loading a surface plate, assembling the primary laminated plate and the surface plate, laminating the primary laminated plate and the surface plate assembly, and releasing and laying. In the production technology, a hot cold pressing overlaying composite process is adopted, the continuous production of the solid wood composite floor is realized through laminating twice; and a main technical index is as follows: formaldehyde emission is less than or equal to 0.3mg/L.
Description
Technical field
The present invention relates to a kind of production method of not having external formaldehyde solid wooden compound floor, belong to the floor manufacture field.
Background technology
Existing manufacturing technique is that employing is colded pressing compound, its major defect is as follows: the one, and the plywood distortion of pressing is big, the solvent that mainly is used adhesive is a water, in the pressing process, moisture carries out balance and moves in the watch core backboard, thereby cause that contracting of watch core backboard rise, finally cause the solid wooden compound floor distortion; The 2nd, the production cycle is long, and production efficiency is low, and the time of colding pressing is 40 minutes, must health, be unfavorable for large-scale production; The 3rd, cost increases more, and influence is sold and enterprise profit.
Summary of the invention
The object of the present invention is to provide a kind of no external formaldehyde solid wooden compound floor and production method; it is by twice pressing; can satisfy consumers in general to the product environmental protection requirement; the performance requirement of the solid wooden compound floor that conventional production method produces can be reached again, external formaldehyde solid wooden compound floor large-scale production target can also be realized not having.
Technical scheme of the present invention is achieved in that no external formaldehyde solid wooden compound floor and production method, it is characterized in that concrete production technology is: take the hot cold pressing mode of production, earlier backboard is carried out preheating, 170 ℃ of preheat temperatures, time 30 ', adopting no aldehyde adhesive to carry out utilizing from external introduction ISM0408C 2-2940H behind the single spreading to backboard then is that a no external aldehyde composite floor board overlays production line, central layer and backboard are carried out the hot cold pressing of assembly, top board is 170 ℃ of the pressing-in temps of central layer, lower platen is that the pressing-in temp of backboard is 20-30 ℃, the time 40 '; Again to the plywood preheating of backboard and central layer, 170 ℃ of preheat temperatures, the time 30 ', and be the central layer gluing at the plywood single face of backboard and central layer, the plywood of dash board and backboard and central layer is carried out the assembly cold pressing, pressing-in temp 20-30 ℃, the time 40 '; Display after the release.
Described no external formaldehyde composite floor board overlays 10 meters per minutes of conveyer belt speed of line.
Described adhesive coating is single spreading, and coating weight is every square metre of 140 gram.
Good effect of the present invention is that its production technology is to adopt the heat subsides combination process of colding pressing, and by twice pressing, realizes the continuity production of solid wooden compound floor; The key technical indexes: burst size of methanal≤0.3 ㎎ ∕ L.
