Abstract
The invention discloses an aid-grinding modifier and a preparation method thereof. The aid-grinding modifier is characterized by being prepared from the following raw materials in percentage by weight: 70 percent of saponification agent, 10 percent of diesel, 5 percent of linseed oil and 15 percent of water, wherein the saponification agent is prepared from the following raw materials in percentage by weight: 25 percent of transparent soap, 20 percent of stearic acid or coupling agent and 55 percent of water. The aid-grinding modifier has the combined functions of aid-grinding and modifying and can effectively decrease the production cost and improve the production efficiency.
Description
Technical field
The present invention relates to a kind of grinding assistant modifier and preparation method thereof, more specifically say a kind of and be applied in the dicalcium powder production process, as lubricant, to improve dicalcium powder mill efficiency grinding assistant modifier and preparation method thereof.
Background technology
In ultrafine heavy calcium powder production technique, grinding aid and properties-correcting agent are separately independent use, and grinding aid commonly used is Diethylene Glycol, is added dropwise to the grinding that grinding aid helps calcite particle at the ball mill point; Properties-correcting agent commonly used is that stearic acid adds paraffin or for coupling agent adds paraffin, process high temperature dissolves, and utilizes the whipping device of high speed, high temperature, properties-correcting agent is adsorbed on equably the surface of coarse whiting powder, makes the powder activation.For the ease of the packing of product, the high-temperature powder after the activation is cooled off rapidly.The process of modified active must be dissolved with the high temperature of properties-correcting agent equipment, high-speed and high-temperature whipping device, cooling apparatus and operation of packaging facilities composition and just can be finished.Like this, not only the time-consuming material that takes also because there is defective in cooling at technological layer, has greater environmental impacts, and is unfavorable for environment protection.
Summary of the invention
The present invention is for avoiding the existing weak point of above-mentioned prior art, and grinding assistant modifier that a kind of grinding aid and modified function unite two into one and preparation method thereof is provided, and to reduce raw materials cost, enhances productivity.
Technical solution problem of the present invention adopts following technical scheme:
The characteristics of grinding assistant modifier of the present invention are that described grinding assistant modifier raw material by weight percentage consists of:
Saponifying agent: 70%, diesel oil: 10%, oleum lini: 5%, water: 15%;
Described saponifying agent raw material by weight percentage consists of: transparent soap 25%, stearic acid or coupling agent 20%, water 55%.
The preparation method's of grinding assistant modifier of the present invention characteristics are to operate according to the following procedure:
A, preparation saponifying agent
Get the raw materials ready by weight percentage and be transparent soap 25%, stearic acid or coupling agent 20%, water 55%.
Respectively transparent soap and stearic acid or coupling agent are reconciled into the pasty state material in right amount with 100 ℃ boiling water, each pasty state material is mixed to get compound, enter in the compound after the water of surplus is heated to be 60-70 ℃, fully stir and generate saponifying agent, be cooled to normal temperature for subsequent use;
B, preparation grinding aid agent
Get the raw materials ready by weight percentage and be saponifying agent: 70%, diesel oil: 10%, oleum lini: 5%, water: 15%;
The saponifying agent and water, diesel oil, the oleum lini rear sealing of the abundant stirring health under 60 ℃ temperature that are cooled to normal temperature were namely got the grinding aid agent in 12 hours.
Compared with the prior art, beneficial effect of the present invention is embodied in:
1, grinding assistant modifier of the present invention in use can once add, and double effects has significant decline on manufacturing cost and use cost, can reach the effect of getting twice the result with half the effort.
When 2, grinding assistant modifier of the present invention uses, be added dropwise to the ball mill mid point, in process of lapping, drip and be sprinkled upon the dicalcium powder particle surface, help grinding effect, the heat that utilize to grind produces simultaneously is adsorbed on the dicalcium powder particle surface equably, thereby so that dicalcium powder activated.Not only improved the grinding effect of ball mill, the activation of powder is finished simultaneously.Avoid in the former powder reactivation process heating and temperature-fall period, reduced by a procedure, thereby efficient is greatly improved, deducted the consumption of electric energy and manpower in intensification, cooling, the high-speed stirring process, reached energy-saving and cost-reducing purpose.Simultaneously also avoided powder in modifying process, to heat up and lowered the temperature and the environmental pollution that causes.
Embodiment
Grinding assistant modifier in the present embodiment raw material by weight percentage consists of:
Saponifying agent: 70%, diesel oil: 10%, oleum lini: 5%, water: 15%;
Saponifying agent raw material by weight percentage consists of: transparent soap 25%, stearic acid or coupling agent 20%, water 55%.
Preparation process:
A, preparation saponifying agent
, enter in the compound after the water of surplus is heated to be 60-70 ℃ respectively with being mixed to get compound behind transparent soap and stearic acid or the coupling agent furnishing pasty state with 100 ℃ boiling water, fully stir and generate saponifying agent, be cooled to normal temperature for subsequent use;
B, preparation grinding aid agent
The saponifying agent and water, diesel oil, the oleum lini rear sealing of the abundant stirring health under 60 ℃ temperature that are cooled to normal temperature were namely got the grinding aid agent in 12 hours.
In the implementation, stearic acid is chosen as Indonesia's pearl 301 stearic acid; Coupling agent is chosen as to deer board coupling agent, model ND-851.
Using method:
By weight percentage, with 4 ‰ consumption, the mode that adopts point to be added dropwise to, grinding assistant modifier of the present invention is added in the dicalcium powder production technique of classification at ball milling, join from the spout of ball mill and jointly enter ball mill among the fine particle of calcite and grind, its grinding-aid effect can substitute Diethylene Glycol fully, and output can improve about 10%.
Through on probation, get grinding assistant modifier of the present invention and insert in the plastic containers, access feed inlet of globe mill with plastic dropper, splash into 4 ‰ ratio by weight percentage,, after 10 hours, spend 40 kilograms of grinding assistant modifiers, produce 10 tons in modification powder, and the micropowder of dense calcium carbonate activation evenly fully, reach modified effect fully, economic benefit is obvious, as calculated, modification powder per ton brownout 50 degree, industrial chemicals ton powder can be saved 20 yuan.
