Description
Technical field
The utility model relates to the superfine talcum powder polypropylene and fills the master batch preparing technical field, particularly a kind of equipment that is used to produce superfine talcum powder polypropylene filling master batch.
Background technology
Talcum powder is cheap inorganic filler commonly used in the plastics industry, and it can improve the dimensional stability of rigidity, modulus and the goods thereof of material effectively, and its cost is significantly reduced; Therefore, talcum powder extensively is used in the modifying plastics industry.But, owing to the bulk density of talcum powder especially superfine talcum powder is little; In the modifying plastics production process, very easily produce dust, pollute workshop, have a strong impact on the healthy of Manufacturing Worker.In addition, because talcous bulk density is little, when modified plastics adopted the processing mode of screw extruder to add talcum powder, the difficult feeding of material had a strong impact on production efficiency.Therefore, how to prepare the high filled polypropylene master batch of superfine talcum powder, for solving dust pollution, seeming very crucial enhancing productivity.
When producing talcum powder filling PP master batch, adopt following two kinds of methods at present in the industry usually: one, elder generation is mixing in banbury; Adding screw extruder again extrudes; Form through the fervent granulation mode of die face at last; Two, through high-speed mixer former material is mixed to more than 100 ℃ earlier, makes material become little lumps; Extrude through double screw extruder again; Finally form through the fervent granulation of water ring die face.
Open day is that the Chinese utility model patent of CN101955604 A discloses " a kind of polyolefin-based nanoscale talcum powder functional agglomerate and manufacturing approach and equipment " for 2011.1.26, publication number.Mentioning method in the literary composition is present typical preparation method: adopt mixer mixing earlier; Adding screw extruder again extrudes; The preparation method who forms through the fervent granulation mode of die face at last.The work characteristics of banbury is: in the banburying chamber, add a certain amount of material, material is the mixing one long period in the banburying chamber, all is delivered to screw extruder then and carries out granulation; Then, pour certain material into toward the banburying chamber again, so successively circulation.In mixing, the process of carrying, material is in a kind of discontinuous state; In addition, because that material is in the mixing chamber of sealing is mixing, the plastifying state of material, fusion time are difficult to accurate assurance.Therefore, the automaticity of whole production line is low, and personnel labor is big, and production efficiency is low.
Open day is that the Chinese utility model patent of CN102040774A discloses " a kind of polypropylene is filled master batch and preparation method thereof " for 2011.5.4, publication number; Mention high-speed mixer in the literary composition and add prepared in twin-screw extruder polypropylene filling master batch: function powder is mainly powdered whiting and blanc fixe; Its bulk density surpasses 1.0g/cm3 (bulk density of superfine talcum powder is less than 0.3g/ cm3), and powdered whiting content is no more than 70%; Therefore, in the production process of the high filling of superfine talcum powder PP, powder is difficult to coated by matrix resin; In addition, adopt high-speed mixer that the raw material premixed time is surpassed 15min, greatly reduce the batch mixing efficient of high-speed mixer.
The Chinese utility model patent of CN 1966562A.Adopt high-speed mixer to add the preparation method of double screw extruder in the literary composition: the mixed function powder agglomerate of 25 ~ 50 parts of calcium carbonate contents, 5 ~ 30 parts of superfine talcum powders; Because the bulk density of calcium carbonate is three times of bulk density of superfine talcum powder; Therefore, the coating problem of such powder basically can be through the mixing solution of twin-screw.But before getting into double screw extruder, this former material need be through high-speed mixer with pre-composition high-speed stirred to 100 ℃ ~ 130 ℃.There are two defectives in such processing technology: 1) mixture temperature reaches the mixing time that needs more than 100 ℃ long (maybe needing heating); 2), and the partial material fusing point is arranged in the middle of the raw material of this series products about 100 ℃ owing to the temperature of high-speed mixer is controlled than difficult; Therefore, there is the agglomerating danger of caking in material, and the normal discharging of high-speed mixer is had a strong impact on.
The day for announcing is that 2011.10.12, notification number are that the Chinese patent of CN101792536 A discloses " a kind of preparation method of carrier-free talcum powder master batch ".Adopt volatile alcohol or ketone diluent in the literary composition, at first bonding agent is diluted to more than 10 times; Bonding agent after will diluting again and talcum powder premixed by a certain percentage; At last at normal temperatures through the extruder extruding pelletization.There is following defective in the method: 1) diluent is difficult to reclaim, and is prone to cause environmental pollution and physical waste, and since the ratio that institute adds diluent up to 15% ~ 35%, follow-up stoving process is difficulty comparatively, the increase manufacturing cost; 2) adopt this processing method resultant that the hardness of particle is very low, in follow-up transportation and use, cause the secondary dust pollution easily; 3) use this extruder equipment pelletizing, make that the product of being cut is different in size, the outward appearance of whole particle is very ugly, and the client is difficult to accept.
In sum, there are above-mentioned all deficiencies in the preparation method and the equipment of the master batch of polypropylene filling at present.
