Abstract
The invention discloses an attapulgite clay suspension agent, which mainly comprises attapulgite clay, other clays, chitosan and alkyl quaternary ammonium salt which serve as raw materials. The attapulgite clay suspension agent has the characteristics of high dispersibility and suspending power in water, has high dispersibility and suspension property in an ethanol solvent, and can be used as a suspended anti-settling agent, a thickening agent, a rheological aid and the like.
Description
Technical field
The present invention relates to a kind of attapulgite clay suspension agent.
Background technology
The suspension of coating refers to coating opposing solid packing layering and sedimentary ability, is an essential property of decision coating property stability.A key character of good coating can keep filler to be suspended in the mounting medium exactly for a long time, and is not stratified, do not precipitate, do not lump and keep the performance uniformity.In recent years, in the suspension agent that coating is used always, the bentonite suspension is ideal, but the anti-heavy effect of bentonite is relatively poor, and its initiator dimethylbenzene is unfriendly to environment.In addition, the bentonitic prices of raw and semifnished materials are more expensive, cost is high, and the high-quality bentonite resource also is tending towards exhausted simultaneously.Therefore, the present invention attempts seeking a kind of alternative organobentonite, cheap and environment amenable coating deflocculant.
Attapulgite clay be with the Attapulgite be main ingredient have a specialty fibers shape crystal habit structure contain Shuifu County's magnesium silicate clay mineral, reach 4,000 ten thousand tons more than in China's proven reserve, store abundant, cheap.Mainly be widely used at present, but the product of higher value application is less as sorbent material.As a kind of inorganic mineral, the avidity of attapulgite clay and organic solvent is poor, and this has just limited its using value aspect high-grade paint greatly.Therefore, attapulgite clay is carried out organic modification handle, so that improve its lipophilicity, suspension and dispersiveness.In recent years, adopt cetyl trimethylammonium bromide to the existing many reports of attapulgite clay modification, although adopt the suspension of the organic attapulgite clay of single organism preparation to increase, especially in high-grade paint, use in the cast paint field but still can not satisfy attapulgite clay with dispersed comparing with original soil.
Chitosan is a kind of natural polymer that extracts from shrimp, crab shell, and chemical name is (1,4)-2-amido-2-deoxidation-β-D-glucose.Owing to contain active amino and oh group in the repeating unit of chitosan, the suspension that can further improve attapulgite clay worked in coordination with in it and cetyl trimethylammonium bromide.
Summary of the invention
At present organobentonite anti-heavy weak effect in coating, problems such as the easy reunion of attapulgite clay the invention provides a kind of attapulgite clay suspension agent.
The objective of the invention is to realize by following scheme:
Attapulgite clay is abundant at China's reserves, and is cheap.But adopt other clay mineral intercalation characteristic, by with the combining of chitosan and alkyl quaternary amine salt, realize the preparation of attapulgite clay base suspension agent.
A kind of attapulgite clay suspension agent, it is characterized in that the suspension agent raw material is made up of attapulgite clay, other clay, chitosan and alkyl quaternary ammonium salts, described other clay is selected from polynite, tired opens up in stone and the sepiolite one or both, and alkyl quaternary ammonium salts is selected from cetyl trimethylammonium bromide; The preparation process of suspension agent is:
Chitosan 1.5-3.5 part of mass fraction is dissolved in the acetic acid solution, after adding methanol solution, add 27.3 parts in attapulgite clay 90-95 part, other clay 5-10 part and alkyl quaternary amine salt, at room temperature stirring reaction is 1～4 hour, obtains the attapulgite clay suspension agent by filtration, drying course successively.
The present invention has following advantage: (1) adopts the modified attapulgite clay of other clay, chitosan, alkyl quaternary ammonium salts preparation, has good dispersity, characteristics that suspending power is strong in water, and have good dispersiveness, suspension simultaneously in alcohol solvent.(2) attapulgite clay stores in China and enriches, and cheap, this preparation technology is simple, compares with wilkinite, and it produces instinct and reduces significantly.(3) in coating, can be used as uses such as suspension anti-settling agent, thickening material, auxiliary rheological agents.The present invention also can be in fields such as makeup, plastic workings except being applied to coating industry.
