Abstract
This invention relates to a method for producing a hydrophobic whit carbon black comprised of rice husk white carbon black and hydrophobic agent. The procedures comprise: add the rice husk white carbon black into the reactor, add in hydrophobic agent and seal for reaction at 80-90Deg C for 400min, take out from the reactor and grind to 1800 order, then send back to the reactor for highly ionic water processing, take out from the reactor and dry at 230-250Deg C, then perform surface activation processing with the drying column temperature at 180-200Deg C, the formula of the hydrophobic is: hydrogen oxide 30%, sodium carbonate 30%, sulfur 10%, alkaline 15%, acid 15%. This invention is characterized that it is different from common white carbon black, can be used in high-grade products of sophisticated and pinpoint techniques, has a water-proof and antiseptic property, and can increase the intensity of the products.
Description
Affiliated technical field:
The present invention relates to industrial chemical industry, especially a kind of Industrial products add the technology of preparing of reinforcer.
Background technology:
At present, white carbon black product has been applied to a lot of fields, and utilizing the white carbon black of rice husk production is in recent years new technology, and carbon is carried in the rice husk burning, makes white carbon black product through technologies such as chemical reaction, filtration, decolouring, washing, the oven dry of grinding draining.And hydrophobic silica white is a kind of excellent high-end additive product that is skillful in white carbon black, and it is to purify through reprocessing on the basis of white carbon black (silicon-dioxide), and performance is higher than another generation product of white carbon black.Be widely used in space flight, naval vessel, rubber, plastics, reach fields such as papermaking, paint, coating, medicine, process hides, along with rubber, plastics develop to colorful direction, its output can not satisfy the demands.Look into new conclusion through what the 2002150200387n of Heilongjiang Province number scientific and technological novelty assessment report provided: " utilize rice husk not appear in the newspapers at home for the research of the hydrophobic silica white aspect of raw material production.”
Summary of the invention:
In order to remedy white carbon black as the deficiency of just holding product, expand its scope of application in high-grade, precision and advanced field, the invention provides a kind of prescription and preparation method of hydrophobic silica white, utilize rice husk for the basis of the white carbon black product of raw material production on concise purification, utilize waste to develop more outstanding product.
The technical solution adopted for the present invention to solve the technical problems is to be made of the white carbon black of rice husk, hydrophobizing agent, the white carbon black of rice husk is gone into reactor, add the hydrophobizing agent sealing, reaction four percentage clocks go out still and are ground to 1800 orders in the temperature of 80-90 degree, reenter still and carry out the macroion water treatment, go out the still oven dry, bake out temperature 230-250 degree, the drying tower temperature keeps the 180-200 degree, carry out surface activation process
The prescription of hydrophobizing agent is: hydrogen oxide 30%, V Soda 30%, sulphur 10%, alkali 15%, acid 15%.
The invention has the beneficial effects as follows, be different from the high-end product that common white carbon black is used in high-quality precision and sophisticated technology, have water proof rot-resistant characteristic, adding in the product to increase its intensity.
Description of drawings:
Accompanying drawing is the hydrophobic silica white technological process of production
Specific embodiment:
Preparation method's most preferred embodiment of hydrophobic silica white is to be made of the white carbon black of rice husk, hydrophobizing agent, the white carbon black of rice husk is gone into reactor, add the hydrophobizing agent sealing, reaction four percentage clocks go out still and are ground to 1800 orders in the temperature of 80-90 degree, reenter still and carry out the macroion water treatment, go out the still oven dry, bake out temperature 230-250 degree, the drying tower temperature keeps the 180-200 degree, carry out surface activation process after the oven dry, product powdery packing.This method also can be used for other white carbon black purification processing.The prescription of hydrophobizing agent is: hydrogen oxide 30%, V Soda 30%, sulphur 10%, alkali 15%, acid 15%.
