Abstract
The invention relates to a method for processing and preparing transparent powder for synthesizing a plastic product, which mainly comprises the steps of removal of impurities from wollastonite, calcination, pulverization, the preparation of a finished product and the like. The method specifically comprises the following steps of: selecting the wollastonite, placing the wollastonite into a stripping machine for stripping and impurity removal, placing the treated wollastonite into a magnetic separator to filter and remove iron, placing the treated wollastonite onto a vibrating screen, and flushing the treated wollastonite by using a tap water flushing device; placing the flushed wollastonite into a drying oven for oven-drying, placing the oven-dried wollastonite into an impact crusher for crushing, placing the crushed wollastonite into a calcining kiln of 1,350 DEG C for calcination, and placing the calcinated wollastonite into an iron-free mill for pulverization and cooling; impregnating the treated wollastonite with a dilute sulfuric acid for 2 hours, performing washing and placing the washed wollastonite into a modification machine of 125 DEG C; and finally adding various organic matters into silica powder, wherein the organic matters comprise RGC, organic tin, a stabilizer, phosphite ester and the coupling agent. The method has the advantages of not influencing original transparency, enhancing the mechanical properties and optical properties of plastics, not softening and deforming the plastic product, reducing the cost of the raw materials, ensuring environmental protection and sanitation, and not producing dense smoke in incineration to pollute the environment.
Description
Technical field
The present invention relates to a kind of transparent powder of plastics, relate in particular to a kind of transparent powder processing and compound method that is used for synthetic plastic product.
Background technology
Transparent powder is a kind of non-metallic minerals of high transparent, the refractive index of its stopping composition itself and the refractive index of most synthetic resins are very approaching, by adopting stopping composition hardness high and low oil number, the surface smoothness that can improve product and the wear-resisting scratch resistance of natural crystal raw material through special processing, help reducing product manufacturing cost, be easy to disperse, various resins are had good wetting property, adsorptivity, stability by force, have good weathering resistance and good erosion resistance.The application of transparent powder is generally industries such as transparent masterbatches, rubber and plastic, coating industry (celluloid paint, PE, PO transparent priming) stearates, hyaluronic acid salt, transparent silica gel, transparent glass glue.But existing in the market product adds original transparent effect is reduced, and cost is higher, can not change the shortcoming that plastic prod runs into high temperature meeting softening transform; In addition, can not reach basic environment protecting.
Summary of the invention
At above defective, the invention provides a kind of environmentally-friendly sanitary, can reduce material cost, do not influence the transparent powder processing and the compound method that are used for synthetic plastic product of former transparency, thereby reach strong, the optical purpose preferably of the plastics mechanical property that makes synthetic plastic product.
For achieving the above object, the present invention is by the following technical solutions:
A kind of transparent powder processing and compound method that is used for synthetic plastic product mainly by steps such as silicon ore removal of impurities, calcining and abrasive dust, preparation finished products, mainly comprises:
(1) silicon ore removal of impurities: manually select silicon ore and put into the machine of delaminating and denude removal of impurities, put into the deironing of magnetic separator inner filtration again, be put on the vibratory screening apparatus, use tap water flushing arrangement to wash away with filtering function;
(2) calcining and abrasive dust: the silicon ore that flushing is finished is at first put into baking oven and is carried out oven dry in 30 minutes, and it is broken to put into the counterattack machine then, puts the temperature control environment again into and be calcining in 1350 ℃ the calcining kiln, puts into no swage grinding machine at last again and carries out grinding and also cool off;
(3) preparation finished product: soaked two hours with dilute sulphuric acid, sulfuric acid is washed down wash clean, put into temperature environment and be 125 ℃ modifying machine with clear water; Get 1 ton of silica flour at last and add various proportioning weight and be organism between 0.6 kilogram-15 kilograms, comprise RGC, organotin, stablizer, phosphite and coupling agent.
The transparent powder that is used for synthetic plastic product of the present invention processes and the beneficial effect of compound method is: can add when the processing plastic goods in right amount, not influence former transparency, energy reinforced plastics mechanical property and optical; Can not make the plastics softening transform, can reduce raw-material cost, make its standard material save 10%-15% for per 100 kilograms; Environmentally-friendly sanitary can not produce thick smoke and contaminate environment when burning in the Refuse bin.
Embodiment
Embodiment 1
