Abstract
The invention discloses bentonite modified by a surface active agent. The bentonite is characterized by comprising the following materials in parts by weight: 90-95 parts of bentonite, 1-2 parts of tx-10, 2-3 parts of silicon carbide, 3-5 parts of polyacrylamide, 3-4 parts of mineral oil, 4.5-6 parts of vinyl carboxylic ester, 3-5 parts of polyvinyl alcohol, 2-3 parts of konjac glucomannan, 1-2 parts of urotropin and 3-4 parts of modified kieselguhr. The bentonite disclosed by the invention has the advantages that the surface modification is carried out on the bentonite by adding tx-10, urotropin and the like, so that the bentonite has good surface activity; by addition of the high-molecular polymer, the surface can be compatible to multiple substances; and by addition of the modified kieselguhr, polyacrylamide and the like, the dispersing effect is improved, so that the bentonite can be used as a water purifying agent, an absorbing agent or a washing powder additive.
Description
Technical field
The present invention relates to industrial filler field, particularly a kind of surfactant-modified bentonite and preparation method thereof.
Background technology
Bentonite is the clay mineral taking montmorillonite as main component, is the natural layer silicate mineral of a class 2:1 type, and its construction unit is that two dimension is to the Si-O tetrahedron of arranging and two-dimentional Al(or Mg to arranging)-O-OH octahedral sheet.In China, bentonite mineral products resource is very abundant, widely distributed, and reserves are at the forefront in the world.Due to the Si-OH that montmorillonite surface exists, can heavy metal ion be fixed between cheating engaging layer by the mode of coordination or co-precipitation.Therefore, natural montmorillonite, as adsorbent, itself also have certain heavy metal ion adsorbed performance, but absorption property is poor, so research is an important job to alta-mud modification.

A kind of surfactant-modified bentonite of the present invention, made by following concrete steps:
(1) bentonite, carborundum, konjac glucomannan, methenamine are mixed and added in grinder, grind 15-20 minute with the speed of 1500-2000 rev/min, take out and dry, pulverize porphyrize, cross 100-200 mesh sieve, obtain mixed-powder stand-by;
(2) tx-10, polyvinyl alcohol, polyacrylamide, mineral oil are put into mixing tank, be warming up between 80-90 DEG C, mix and blend half an hour, continue to add vinyl carboxylate, continue to be warming up to 130-160 DEG C, mix and pour out after 15-20 minute, obtain material modified;
(3) mixed-powder is mixed with material modified, add suitable quantity of water, stir and grind 2-3 hour, form suspension stand-by;
(4) suspension is mixed with modification infusorial earth, stir 10-15 minute under 800-1000 rev/min, dry, be ground into 200-400 order powder and get final product.
The invention has the beneficial effects as follows: the present invention carries out surface modification by adding tx-10, methenamine etc. to bentonite, make it to there is good surface-active, add high molecular polymer, making it surface can be compatible with many kinds of substance, add modification infusorial earth and polyacrylamide etc., improve dispersion effect, can be used as water purification agent, adsorbent or washing powder additive.
