Problems solved by technology

[0014] When the above-mentioned molding techniques are made into industrial pallets, an important problem is that they cannot have a basically stable formula suitable for using waste furniture and furniture manufacturing waste and other construction wood waste to produce industrial pallets with stable quality. The published formula is only suitable for relatively single materials, usually only suitable for shaving raw materials
[0015] When using organic solid waste from the furniture industry to manufacture industrial pallets, there is still a technical bottleneck that needs to be faced, that is, the messiness of the source of organic solid waste from the furniture industry affects the quality of the final product. An effective way to solve the problem is to increase the The crushing fineness of organic solid waste, but there will also be a problem, that is, the product may be scorched when the temperature reaches a certain level during the molding operation, and the brittleness of the finished product will increase, seriously affecting the strength and durability of the finished product
[0016] Another problem is that the formaldehyde content in the organic solid waste of the furniture industry is relatively high. If the method of removal is adopted during the treatment, the cost may be higher. This is also a problem that the present invention needs to face

Embodiment 1

[0070] The first step is to prepare modified wood material powder

[0071] Collect woody solid waste from the furniture industry and crush it into 10-1000 mesh waste woody material powder. The prepared modified woody material powder contains:

[0072]100 kg of waste wood material powder, 10-13 kg of nano-scale calcium carbonate and / or nano-scale calcium sulfate (the average particle size of both is 10-100nm), 2-2.5 kg of titanate coupling agent, 5-6 kg of silicone oil kg, 0.8-1.2 kg of stearic acid.

[0073] The above-mentioned nano-scale calcium carbonate or / and calcium sulfate and the waste wood material powder that has been dried in a fluidized furnace and controlled to keep the moisture below 3% are vigorously stirred in a high-speed mixer at 1200-1500 rpm and 90-110°C for 20 minutes. Minutes, then add titanate coupling agent, stearic acid, silicone oil and continue mixing for 6-8 minutes to obtain modified wood material powder.

[0074] The second step is to prepare the...

Embodiment 2

[0083] Collect wood solid waste from the furniture industry, crush it into 10-100 mesh (abbreviated as: waste wood material powder in the present invention), and prepare modified wood material powder according to the following ratio:

[0084] 100-150 kg of waste wood material powder, 20-27 kg of nanoscale calcium carbonate and / or nanoscale calcium sulfate (the average particle size of both is 10-100nm), 3-6 kg of titanate coupling agent, stearin 1-2.5 kg of acid, 5-9 kg of silicone oil.

[0085] Stir 50% of the above-mentioned nano-scale carbonic acid and / or nano-scale calcium sulfate with the waste wood material powder whose water content is controlled below 2% after drying in a high-speed mixer for 12-20 minutes, and then add titanate coupler The joint agent, stearic acid and silicone oil continue to mix for 7-10 minutes and then add the following substances:

[0086] The remaining 50% of nano-scale calcium carbonate and / or nano-scale calcium sulfate, 8-10 kg of ultra-fine ...

Embodiment 3

[0091] Use sawdust, crop stalks, rice bran, other plant stems and leaves, paper, etc. to replace the waste woody material powder, or their mixture, and refer to Example 1 or 2 for other methods.

Abstract

Provided is a recycling technology for manufacturing industrial pallets by utilizing organic solid waste in the furniture industry. The invention belongs to the field of transforming solid waste into useful articles, and especially belongs to the solid waste recycling field of manufacturing industrial pallets by utilizing wood waste in the furniture industry. The industrial pallets are mainly composed of waste wood material powder, nano-scale calcium carbonate and / or calcium sulfate whiskers, a titanate coupling agent, stearic acid, silicone oil, plastics and / or waste plastics, aluminum hydroxide, chlorinated polyethylene (CPE), maleic anhydride, dicumyl peroxide (DCP) and paraffin wax. The key point of the technology is that the industrial pallets contain the calcium sulfate whiskers. The manufactured industrial pallets are of high strength, can be used repeatedly, have a smooth appearance, and have very high environmental benefit.

Description

technical field [0001] The invention belongs to the field of converting solid waste into useful products (B09B 3 / 00), in particular to a method of using wood waste (including construction wood waste) in the furniture industry to manufacture articles for forklift loading, unloading, moving and carrying The field of solid waste recycling of industrial pallets. Background technique [0002] Now the whole society produces a large amount of wooden garbage in the process of housing decoration, relocation, and renewal of residents' waste and old furniture, which cannot be processed. According to estimates, every 5 to 8 years, many building materials and furniture products will enter the phase-out period. When consumers start to carry out secondary decoration, these original building materials and furniture products become the most eye-catching garbage. "The old furniture does not match the newly renovated room. I asked someone to carry it downstairs. I tried to sell the old furni...
