Abstract
The invention discloses a preparation method of polydimethyl siloxane ground limestone superfine powder. The preparation method is characterized by comprising the following steps: adding coarse ground limestone powder into grinding equipment; based on weight percentage of the coarse ground limestone powder, adding 10-12 percent of an adjuvant at the temperature of 85 to 95 DEG C; grinding at a high speed to prepare modified calcium carbonate superfine powder of which the particle size is 0.1 to 10 micrometers, wherein the adjuvant consists of the following components in parts by weight: 3-5 parts of polydimethyl siloxane, 2-3 parts of ethyoxyl aminoethyl laurate, 2-3 parts of an aluminic acid ester coupling agent, 5-8 parts of sodium carbonate and 5-8 parts of glycol. The preparation method disclosed by the invention has the advantages of being scientific and reasonable in design, simple in process, safe, reliable, easy to control, convenient to operate, suitable for large-scale production, low in production cost and the like.
Description
Technical field
The invention belongs to a kind of production method of calcium carbonate powder.
Background technology
At present, calcium carbonate is widely used in papermaking, plastics, plastics film, chemical fibre, rubber, tackiness agent, sealing agent, daily-use chemical industry, makeup, building materials, coating, paint, ink, putty, sealing wax, putty, carpet veneer is packed, medicine, food is (as chewing gum, chocolate), in feed, its effect has: increase small product size, reduce costs, improve processing characteristics (as adjusting viscosity, rheological property, curability), improve dimensional stability, reinforcement or half reinforcement, improve printing performance, improve physicals (as thermotolerance, extinction, wear resistance, flame retardant resistance, whiteness, glossiness) etc.The technological process of production of water-ground limestone has two kinds.Dry technology for production flow process: the first calcite, Wingdale, chalk, shell etc. that ship from stone quarry of picking, to remove gangue; Then with crusher, coarse breaking is carried out to Wingdale, cover that (pendulum-type) abrasive dust is broken obtains microlith limestone flour again with thunder, finally carry out classification with grading machine to abrasive dust, the powder meeting granularity requirements is put in storage as the packing of product, otherwise returns pulverizing mill abrasive dust again.Wet process technique flow process: first dry method fine powder is made suspension and be placed in grinding machine and pulverize further, just obtained superfine heavy calcium carbonate after dehydration, drying.
Retrieve through Chinese publication, find calcium carbonate application for a patent for invention 53; Do not find the scheme identical with present patent application.
Summary of the invention
The object of the invention is to; A kind of dimethione micropowder of dense calcium carbonate preparation method is proposed.
Dimethione micropowder of dense calcium carbonate preparation method of the present invention, it is characterized in that: coarse heavy calcium carbonate powder is added in grinding plant, at 85 ~ 95 DEG C, with the weight percent meter of coarse heavy calcium carbonate powder, add the auxiliary agent of 10-12%, through speed lapping, obtained particle diameter is the modified superfine Paris white of 0.1 ~ 10 micron; Described auxiliary agent, by weight, dimethione 3-5 part, oxyethyl group bay cruel amine 2-3 part, aluminate coupling agent 2-3 part, sodium carbonate 5-8 part, ethylene glycol 5-8 part forms.
The present invention compared with prior art its beneficial effect is: have design science reasonable, and technique is simple, safe reliability, is easy to control, easy to operate, is applicable to scale operation, the advantages such as production cost is low.
