Abstract
The invention discloses a method for preparing organic bentonite anti-settling agent, and belongs to the field of chemical building materials. The method comprises the following steps: taking organic bentonite as the main raw material, adding a polar additive namely ethanol with a water content of 5%, wherein the ethanol can carry out solvation on the surface of a film that has not been substituted by organic cations so as to reduce the attractive force between films, and polar additive is penetrated into the space between the films by grinding so as to reduce the attractive force between films; or adding auxiliary agents such as zinc stearate, liquid paraffin, sodium dodecyl sulfonate, and phosphoric acid-propane diamine to greatly improve the using performance of the organic bentonite anti-settling agent. The anti-sagging performance and leveling performance of a coating can be well balanced by the organic bentonite anti-settling agent. Moreover, the organic bentonite anti-settling agent can enable a paint system to have a high thixotropic property, has an excellent thickening and anti-settling function, and thus is capable of effectively preventing the settlement of pigment and filling materials in paint.
Description
Technical field
Product of the present invention belongs to chemical building material field, particularly relates to a kind of method preparing organobentonite anti-settling agent.
Background technology
Anti-settling agent is the rheology control agent of a class coating, and it makes coating have thixotropy, and viscosity improves greatly, and produce material impact to the production of coating, storage, application and film performance, thus its use comes into one's own day by day.Organobentonite take natural smectite as raw material, makes by adding organic insulating covering agent, and organobentonite prevents the mechanism precipitated from being the rheological property of change system, makes it have thixotropy, thus prevents color stuffing sedimentation.Organic bentonite uses as anti-settling agent, can add directly add two kinds of modes with powder with preparation.Result shows, directly add with powder, the coating leveling of coating can be made good, no sag phenomenon, and extend the settling time of pigment, the performance of coating can be improved significantly, but because color and luster is dark, poor transparency, easily produce brush mark, increase solvent load, paint liquid-solid body burden and be difficult to ensure card, therefore also have certain limitation during application.In order to improve the limitation that organic bentonite produces, the way of adding auxiliary material can be adopted to make preparation to improve its performance, the present invention take organobentonite as main raw material, the auxiliary material added has: polar additive, as the ethanol of moisture 5%, the slice surfaces that the ethanol of moisture 5% can cover at unsubstituted organic cation carries out solvation, thus reduces the magnetism between thin slice, and impel polar additive to infilter between thin slice by grinding, reduce the magnetism between thin slice; Also can add Zinic stearas, whiteruss, sodium laurylsulfonate, phosphoric acid propylene diamine, the interpolation of these auxiliary materials improves greatly by making the use properties of organobentonite anti-settling agent, product can balance sag resistance and the levelling property of film preferably, the thixotropic property that lance coating system is higher can be composed, and there is excellent thickening, anti-settling effect, effectively can prevent the precipitation of pigment in coating, filler.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of method that batch prepares organobentonite anti-settling agent, this anti-settling agent take organobentonite as main raw material, be equipped with multiple auxiliary materials again to produce this product, this product adds sag resistance and the levelling property that can balance film in coating preferably to as the anti-settling agent of coating, the thixotropic property that lance coating system is higher can be composed, and there is excellent thickening, anti-settling effect, effectively can prevent the precipitation of pigment in coating, filler.The raw material producing the use of this product has: organobentonite 20%-22%, concentration are ethanol 73%-75%, Zinic stearas 1%, whiteruss 2%, sodium laurylsulfonate 1%, the phosphoric acid propylene diamine 1% of 95%.
The present invention can be achieved through the following technical solutions:
Prepare a method for organobentonite anti-settling agent, its feature is made up of following steps:
(1) by the concentration of formula ratio be 95% ethanol send into stirred pot, start stirrer stir, rotating speed is that 25 turns of ∕ divide, and temperature in stirred pot is increased 40-45 DEG C, adds the organobentonite of formula ratio, stirring reaction 1.0-1.2 hour.
(2) material in stirred pot is sent into planetary mixer, be cooled to normal temperature, continue to stir, add the Zinic stearas of formula ratio, whiteruss, sodium laurylsulfonate, phosphoric acid propylene diamine successively, after stirring reaction 0.5-0.7 hour, obtain finished product.
(3) using method of organobentonite anti-settling agent is: add in coating stirring in the ratio of 3-5%.
Temperature of reaction in stirred pot described in step (1) is 42.5 DEG C.
Normal temperature in planetary mixer described in step (2) is 10-30 DEG C.
The invention has the beneficial effects as follows: the preparation method providing a kind of organobentonite anti-settling agent, this preparation method's technique is simple, good product quality, product uses mainly as the anti-settling agent of coating, product can balance sag resistance and the levelling property of film preferably, the thixotropic property that lance coating system is higher can be composed, and there is excellent thickening, anti-settling effect, effectively can prevent the precipitation of pigment in coating, filler.
