Description
Technical field
The present invention relates to Material Field and pallet manufacture field, and in particular to a kind of carrying composition material, use material
The pallet and the preparation method of pallet for processing.
Background technology
Flyash is a kind of solid waste produced in coal-burning power plant's production process, yield account for coal-fired total amount 5~
20%.About 500,000,000 tons of China's flyash annual emissions, high-volume more than 2,000,000,000 tons of current China's flyash heap, storage ash field land occupation
About 4 × 104km2, this not only severe contamination environment, also occupies substantial amounts of land resource.It is prepared by the flyash that adulterated at present
The technology applications such as light material, refractory material, heat-insulating heat-preserving material, construction material, domestic ceramics material, but flyash is entered
The effect of row high value added utilization is not apparent.
During ferrosilicon ash is smelting ferrosilicon, the flue dust escaped with waste gas is collected treatment and is formed through special capturing device
A kind of industrial residue.At present, the accumulating amount and yield of domestic ferrosilicon ash cause severe contamination up to more than 1,000,000,000 tons to environment.
At present for the grey use of ferrosilicon primarily as cement, the additive of refractory material, the adhesive of metallurgical briquetting, chemical products
Cast of the inserts of dispersant, rubber and plastics, the plastic packaging material of electron trade and electrician trade etc..These technologies cannot be to silicon
Iron ash carries out high value added utilization, it is therefore desirable to seek new method to comprehensively utilize ferrosilicon ash.
Polyvinyl chloride (PVC) resin is the thermal plasticity high polymer being polymerized by vinyl chloride (VC) monomer, is in the world four
One of big general-purpose plastics.It is estimated that, the demand of China PVC is with annual 10% speed increase, and PVC's is a large amount of using inevitable
Cause the generation of a large amount of waste products, these waste products pollute the environment for the survival of mankind such as river, lake.The recycling of PVC,
Can not only solve environmental issue, and the pressure of resource scarcity can be alleviated, especially in the present of PVC cost of material continuous rises
My god, its recycling has great importance.
It is used for the pallet of bearing article currently on the market, material is broadly divided into wooden, plastics and steel, but each
There is irremediable shortcoming：Wood pallets have make moist after it is perishable, for assemble iron nail easily exposure destroy outside
Product appearance；Common plasticses pallet intensity is relatively low, bearing capacity is low, size fixed and flexible is poor, aging be not durable easily；Iron pallet
Weight weight, price are high, and waste a large amount of iron and steel resources.
Patent CN102993604A discloses a kind of fly ash foamed sheet material, is added using flyash, Corvic etc.
Work is obtained foaming plate, for indoor floor or outdoor wallboard.Patent 104177794A discloses a kind of pallet and its preparation side
Method, is prepared from using recycled PET and Paris white etc..
The content of the invention
Technical problem present in currently available technology is that conventional art lacks takes into account moisture resistance, intensity and bearing capacity
Strong and lightweight carrying pallet, on preparing carrying material using flyash, ferrosilicon ash and polyvinyl chloride reclaimed materials
Or the patent of novel environment friendly pallet there is no report.Do not propose ferrosilicon ash at present for loading material, be not proposed for powder yet
Coal ash, the ferrosilicon ash method related to the comprehensive utilization of polyvinyl chloride reclaimed materials, for by waste product flyash, ferrosilicon it is grey and
Polyvinyl chloride reclaimed materials carries out high added value processing and recycles not specified (NS).
The present inventor has found to solve above-mentioned technical problem, containing substantial amounts of sieve and silica-sesquioxide in flyash, in ferrosilicon ash
Containing a large amount of unsetting Si oxides, if flyash be used with the main component in ferrosilicon ash, and combine poly-
Processability and physical and chemical performance that vinyl chloride reclaimed materials has, it is possible to " turning waste into wealth ", reach the mesh of environmental protection
's.One kind carryings composition material of the invention, using including flyash, ferrosilicon be grey, polyvinyl chloride reclaimed materials raw material, and

Sieved using 20~200 eye mesh screens；
(2) dispensing mixing：Flyash that step (1) is obtained, ferrosilicon ash, polyvinyl chloride reclaimed materials and add as needed
Fine particle calcium carbonate, wood powder, stabilizer, modifying agent, foaming agent, foaming control agent, the first lubricant and the second lubricant by weight
Even mixing, obtains carrying and is mixed with composition material, and wherein mixing temperature is 110-130 DEG C, then is cooled to 20-50 DEG C；
It is preferred that pressing ferrosilicon ash, polyvinyl chloride reclaimed materials and fine particle calcium carbonate, wood powder, stabilizer, modifying agent, foaming agent, foaming control agent, the first profit
Lubrication prescription and the second lubricant are (25~40) by weight：(3~20)：(25~40)：(10~20)：(0~8)：(1~3)：(1
~2.5)：(0.1~1)：(2~5)：(0.1~1)：(0.1~1) is cooled to 20-50 DEG C in 120-140 DEG C of uniform mixing；
Stabilizer used by the present invention can be the conventional stabilizer of market purchase.The preferred complex lead salt stabilization of stabilizer
Agent, more preferably dustless lead salt compound stabilizer, the wherein content of lead oxide are 53~57wt%, the content of calcium oxide for 40~
44wt%.Calcium zinc stabilizer contains the main components such as calcium salt, zinc salt, lubricant, antioxidant, and conventional has liquid calcium zinc stabilization
Agent, solid calcium zinc stabilizer and pasty state calcium zinc stabilizer.It is preferred that calcium zinc stabilizer 10-20wt% containing zinc stearate, calcium stearate
5-10wt%, calcium carbonate 40-50wt%, hydrotalcite 10-20wt%, calcium hydroxide 5-10wt%, pentaerythrite 1-3wt%, stone

Modifying agent used by the present invention can be the conventional stabilizer of market purchase.Modifying agent preferably comprises haloflex
And/or acrylate copolymer.Acrylate copolymer used by modifying agent preferably is selected from butyl acrylate thing, methacrylic acid
In methyl esters-butadiene-styrene graft copolymer, polyacrylate, methyl methacrylate-butyl acrylate copolymer one
Plant or several.
It is unqualified after testing or using after scrapping and reclaiming in carrying composition material, at the techniques such as broken, milling
Reason is recycled material, is added in the form of external feeding, and additional ratio is 5~15%, for example：In the normal raw materials for production of 100kg, can
It is well mixed to use to add the reclaimed materials of 5~15kg.
(3) extrude：The material extrusion moulding for being obtained step (2) using extrusion shaping machine, obtains carrying composition material
Material.Wherein, the extrusion shaping machine includes feeding part and extruder member, and the feeding part includes feeding motor, hello barrel

Comparative example 1
It is 23%, the weight percent of polyvinyl chloride reclaimed materials with the percentage by weight that the difference of embodiment 1 is flyash
Than being 37%.
The material for obtaining cannot be applied to the production of pallet product.
Comparative example 2
It is 22%, the weight percent of polyvinyl chloride reclaimed materials with the percentage by weight that the difference of embodiment 1 is ferrosilicon ash
Than being 33%.
Because ferrosilicon ash light weight viscosity is big, this experiment equipment used is used, it is impossible to the technological parameter stablized.
