Abstract
The present invention relates to a method for preparing gross rubber, particularly to a packing material and application thereof for directly mixing gross rubber without influencing the property of the gross rubber and vulcanized rubber. The components and the quality shares of the packing material which is directly mixed into nonpolar rubber contain 100 shares of low-density polyethylene, 10 to 25 shares of linear low-density polyethylene and 3 to 20 shares of polystyrene. The components and the quality shares of the packaging material which is directly mixed into polar rubber contain 100 shares of polyvinyl chloride, 25 to 35 shares of dicapryl phthalate, 5 to 10 shares of dibutyl phthalate, 0.2 to 0.6 share of calcium stearate, 0.1 to 0.3 share of zinc stearate, 0.2 to 1 share of calcium carbonate and 0.1 to 0.2 share of paraffin wax. The plastic film packing materials which are prepared by adopting the formula respectively pack granular or powdery materials which are needed by the gross rubber production according to the different kind standards and different quality standards which are needed by a rubber production plant. The packing material of the present invention can be directly fed and has no need to be unpacked, and the packing material of the present invention achieves the purposes of cleaning production, device simplification and product quality increase.
Description
Technical field
The present invention relates to rubber mixed preparation, specifically be meant and a kind ofly directly sneak into rubber mixedly, and do not influence the wrapping material and the application thereof of rubber mixed and cured properties.
Background technology
Carbon black that present existing rubber is used or filler (as treated carbonates, white carbon black, potter's clay etc.) are to pack with wrapping paper, composite plastic film woven bag, plastic packaging bag etc.After the packing that carbon black or filler factory have, be transported to and use factory; What also have uses tank car in bulk, transports directly to use factory.Existing bag, feeding system have following four problems: 1, feeding system is seriously polluted to workshop condition.Though Banbury mixer has all adopted the subsidiary engine feeding system at present, basically mechanize and automatization have been realized, compare with manually feeding intake, alleviated working strength of workers greatly and to the pollution of environment, but, drop into storage tank, by the automatic weighing of prescription requirement because raw material will be gone through and unpack, put into processes such as middle hopper, dust from flying is all arranged in these processes.2, inaccurate because of ingredients by weight causes mix quality to descend or the quality instability.Its reason has two: one, and in order to reduce the pollution of workshop condition, the workshop all is equipped with powerful exhausting system, can see that the billowing smoke taken away by strong blower fan when mixing feeding intake, and accurately the various raw materials of weighing are no longer accurate.Carbon black particularly, just enters banburying chamber until the height through 2-3 rice at whole conveying, storage, weighing, all is loose shape, freely falling body, and when ram pressed down, just high spray rose, at this moment easier being taken away.Its two, the weighing of many carbon black feeding systems is inaccurate, though Controlling System has warning device, does not have corresponding apparatus after the display alarm, operator can't increase and decrease.Can find out all that from this two aspect existing carbon black feeding system has a strong impact on the accuracy of batching, cause the mix quality fluctuation very big.3, the carbon black pellet breakage is many.Disperse and alleviate wind to raise pollution in order to help carbon black sneaking in sizing material, present most carbon blacks have all carried out granulation.But carbon black is after process such as storing, weighing feeds intake, and it is damaged in various degree that carbon black pellet is subjected to, and has increased that sooty flies upward loss and influenced the sooty dispersion effect when mixing.4, subsidiary engine carbon black feeding system construction cost is big on the Banbury mixer, and maintenance difficult is easily stopped up during system carries, often operation in spite of illness.
Summary of the invention
The objective of the invention is to overcome the problem that prior art exists, use a kind of rubber mixed wrapping material that are used for directly sneaking into.
Another object of the present invention is to use wrapping material of the present invention to pack rubber mixed raw material, uses producer to need not to unpack and can directly feed intake, the purpose that reaches cleaner production, simplified apparatus and improve the quality of products.
The objective of the invention is to realize by following measure.
A kind of wrapping material of directly sneaking into rubber mixed raw material is characterized in that:
(1) it is as follows directly to sneak into wrapping material component and mass parts thereof that non-polar rubber uses:
100 parts of new LDPE (film grade)s,
10～25 parts of linear low density polyethylenes,
3～20 parts of polystyrene;
(2) it is as follows directly to sneak into wrapping material component and mass parts thereof that polar rubber uses:
100 parts of polyvinyl chloride,
25～35 parts of dioctyl phthalate (DOP)s,
5～10 parts of dibutyl phthalates,
0.2～0.6 part of calcium stearate,
0.1～0.3 part of Zinic stearas,
0.2～1 part in lime carbonate,
0.1～0.2 part in paraffin.
A kind of application of directly sneaking into the wrapping material of rubber mixed raw material, it is characterized in that, adopt the plastic film packaging material of the described formulation of claim 1, pack the granular or powder raw material of the required use of rubber mixed production by the specification of the required different varieties of rubber production factory, quality respectively.
Non-polar rubber can directly be sneaked in natural rubber, styrene-butadiene rubber(SBR), cis-1,4-polybutadiene rubber, terpolymer EP rubber or the polyisoprene rubber with wrapping material and be used.Polar rubber can directly be sneaked in paracril or the chloroprene rubber with wrapping material and be used.
The present invention compared with prior art has following advantage and beneficial effect:
(1) because the required mechanical property requirements of the promptly satisfied packing of wrapping material of the present invention can directly be sneaked in the rubber unvulcanizate raw material again, rubber production factory need not to unpack and can enter mixing operation, overcome the pollution that dust from flying brings, the purpose that has reached cleaner production, simplified apparatus and effectively improved the quality of products.
(2) but subsidiary engine carbon black or fleut feeding system cancel all on the existing Banbury mixer have been saved the operation of a large amount of construction costs and equipment, maintenance cost.
(3) rubber plant's desired raw material kind, complete in specifications is easy to deposit in the warehouse, gets the raw material of all size earlier by charger sheet, is placed on rubber and feeds intake on the travelling belt, drops into banburying chamber and get final product, has therefore dwindled production site, has reduced the possibility of pollution.
(4) guarantee the accuracy of ingredients by weight, and do not influenced rubber unvulcanizate and cured properties, thereby improved quality product.
(5) the present invention is applicable to big or small Banbury mixer, and what turnout was little can manually prepare burden, and turnout is big adopts modern full automatic warehouse style management.
