The foam layer in the foam mattress is mainly polyurethane foam. Polyurethane foam has ultra-low temperature thermal conductivity, weather resistance and heat preservation; high-efficiency insulation, sound insulation, waterproof and moisture-proof characteristics; but people have the habit of liking the new and disliking the old, and seeing more and more new mattresses Even if the old mattresses in use are not broken, they must be discarded and replaced with new ones, or all old mattresses will be replaced due to moving to a new house, so many mattresses that are not broken are discarded and taken to landfill or incineration , very wasteful

Embodiment 1
[0019] Both the first base material layer 1 and the second base material layer 2 are made of plywood, and the glue is made of urea-formaldehyde resin.
[0020] Its preparation steps are:
[0021] A. Process the recovered old foam mattress of 1200mm*2000mm, and take out the foam layer from the old foam mattress;
[0022] B. Prepare two 1200*2000mm plywood, and apply urea-formaldehyde resin on one side of the two plywood respectively;
[0023] C. According to the sequence of plywood, old foam mattress foam layer, and plywood, lay the boards well, and glue the side of the glue to the foam layer, and laminate them well to get the basic composite board;
[0024] D. Send the laminated composite panel into a cold press, and cold press to shape it. The temperature of the cold press is 20° C., the pressure is 5 Mp, and the cold press time is 10 minutes to obtain a composite wood-based panel.
Embodiment 2
[0026] Both the first base material layer 1 and the second base material layer 2 are made of plywood, and the glue is made of phenolic resin.
[0027] Its preparation steps are:
[0028] A. Process the recycled 1500mm*2000mm old foam mattress, and take out the foam layer from the old foam mattress;
[0029] B. Prepare two pieces of 1500*2000mm plywood, and apply phenolic resin to one side of the two pieces of plywood respectively;
[0030] C. According to the sequence of plywood, old foam mattress foam layer, and plywood, lay the boards, and the glued side is bonded to the foam layer, and the laminate is good to get the basic composite board;
[0031] D. Send the laminated composite panel into a cold press, and cold press to shape it. The temperature of the cold press is 10°C, the pressure is 8Mp, and the cold press time is 15min, to obtain a composite wood-based panel.

Abstract
The invention discloses a method for producing a composite artificial board by utilizing an old foam mattress and relates to the technical field of artificial boards. The composite artificial board comprises two base material layers. A sound insulating and heat preserving layer is arranged between the base material layers and is a foam layer of the old foam mattress. The base material layers and the sound insulating and heat preserving layer are bonded through glue. According to the manufacturing method, one face of the board is coated with the glue, stacked with the foam layer of the old foam mattress, and formed in a pressing mode to obtain the composite artificial board of a certain specification. The strength of the manufactured artificial board almost the same as that of a general artificial board in the market; as the foam layer of the old foam mattress is arranged, the foam layer is made of polyurethane foams with good sound absorbing and heat preserving performance, the sound insulating and heat preserving effects are better than those of the general artificial board, what's more, the old foam mattress difficult to treat can be recycled, the process is simple, and the production efficiency is high.
Description
technical field [0001] The invention relates to the technical field of wood-based panels, in particular to a method for producing composite wood-based panels using old foam mattresses. Background technique [0002] my country is one of the countries lacking forests and materials. The gap in timber supply relies heavily on imports. With the rapid development of the construction industry and furniture industry in recent years, the domestic demand for timber has increased sharply. Therefore, the development of the wood-based panel industry has effectively alleviated the shortage of timber in my country. Consumption is an important way to save wood. [0003] The main material of the foam mattress is foam. The foam mattress can conform to the curve of the body. While providing support, it is soft and elastic. At the same time, it can cushion the movement of the body. Mattresses have been favored and loved by Everbright consumers, and more and more people are buying foam mattresse...
