Abstract
The invention relates to woodwork and fiber production method used polyethylene and thermoplastics as adhesive. It belongs to the technique field used woodwork and other non woodwork plant fiber to manufacture building board and its surface decorating, and used woodwork building board to manufacture composite floor. The technique problem needed to solve is that the manufacturing of veneering building board, composite floor, melamine decorative board, flakeboard, fiber board in decorating and furniture industry is mainly used urea-formaldehyde resin. The defect is that the urea-formaldehyde glue contains free formaldehyde which is harmful to human body health. Its technical proposal is as follows: hot pressing pressure is same with the pressure produced by urea-formaldehyde resin; hot pressing temperature is 20-50 centigrade degree which is above thermoplastics melting point; hot pressing time is different according to different hot pressing temperature.
Description
One, technical field the invention belongs to timber and other non-lignocellulose plant fibres and produces wood-based plate and wood-based plate surface decoration, and with the technical field of timber and Wood-based Panel Production composite floor board.
Two, background technology
Produce shaving board with timber and other non-lignocellulose plant fibres now, fiberboard and at glued board, core-board (lumber core).Shaving board, fiberboard and other people make bonding finishing material on the plate surface and (comprise veneer, printed decoration paper, materials such as melamine decorative board), production is with solid wood, the composite floor board that wood fibre and other non-lignocellulose plant fibre artificial boards are base material, the urea-formaldehyde resin adhesive of main usefulness.Its shortcoming is to contain free formaldehyde, and formaldehyde has carinogenicity to human body, and makes the easy cases with leukemia of people, pharyngitis, asthma.To this, national departments concerned has been formulated standard to the formaldehyde content of air in the formaldehyde content of wood-based plate and the interior decoration.
Detected children room in 2005 according to reports of newspaper Beijing relevant department, it is 100% that formaldehyde content exceeds standard, and it is 99% that pregnant woman room formaldehyde content exceeds standard, and it is 69.2% that the classroom formaldehyde content exceeds standard.The annual out-patient who causes because of room air pollution in the whole nation reaches 220,000 person-times.Death reaches 110,000 people.Defective artificial plate not only can be detrimental to health, and some projects not allow to use.
Three, summary of the invention is done no-formaldehyde adhesive with polyethylene and other thermoplasticss and is applied to the wood-based plate veneer, produces composite floor board, melamine decorative board, shaving board, fiberboard.
With make tackiness agent of urea-formaldehyde glue and compared following characteristics:
1, formaldehydeless especially polyethylene is widely used in the food product pack industry, and human body is not had other harm yet.It is safest a kind of tackiness agent.
2, because thermoplastics does not contain moisture, so product bubbling not.
3, the water tolerance of glue-line is better than urea-formaldehyde glue.
4, the ageing resistance of glue-line is better than urea aldehyde.The long service life of product, unmodified urea-formaldehyde glue is 3 years in the outdoor ageing-resistant time, modified urea-formaldehyde glue is 6 years in the outdoor ageing-resistant time.And vinyon is more than 100 years at outdoor degradation time.This is an important feature of the present invention.
Four, the same pressure sintering that adopts of embodiment with urea-formaldehyde glue.
(1) the wood-based plate veneer is at glued board, core-board (lumber core).Shaving board, fiberboard and other people make and cover last layer polyethylene or other thermoplastic films on the plate surface, or powder, spread veneer then in the above, printed decoration paper, materials such as melamine decorative board, hot pressing forms.
(2) produce composite floor board
1, is combined as base material with veneer or veneer and reel bar
Covering last layer polyethylene or other thermoplastic films or powder between veneer and the veneer or between veneer and the reel bar, on uppermost veneer, also cover last layer polyethylene or other thermoplastic films or powder equally, and then cover last layer solid wood veneer or have the wearing layer of decorative paper, hot pressing forms.
2, with the high density fiberboard be base material
Cover last layer polyethylene or other thermoplastic films on high density fiberboard, or powder, and then cover last layer solid wood veneer or have the wearing layer of decorative paper, hot pressing forms.
(3) melamine decorative board
At decorative paper and bottom paper, cover last layer polyethylene or other thermoplastic films between bottom paper and the bottom paper, or powder, hot pressing forms.
Characteristics: the flexibility that has increased melamine decorative board
(4) make shaving board
Polyethylene or other thermoplastics powder are stirred in the wood shavings, under certain temperature and pressure, process then.
(5) make fiberboard
Polyethylene or other thermoplastics powder are stirred in the fiber, under certain temperature and pressure, process then.
Claims (5)
1. bonding finishing material on wood-based plate: at glued board, core-board (lumber core), shaving board, fiberboard and other people make bonding finishing material on the plate surface (comprising veneer, printed decoration paper, materials such as melamine decorative board).
2. production composite floor board: produce with solid wood, wood fibre, other non-lignocellulose plant fibre artificial boards are the composite floor board of base material.
3. production melamine decorative board.
4. production shaving board
5. producd fibers plate.
