Abstract
The invention relates to an antistatic agent composition which comprises a monohydric alcohol phosphate monoester/diester component and a dihydric alcohol phosphate monoester/diester component. The antistatic property and lubricating property of the antistatic agent composition provided by the invention are obviously superior to those of the corresponding single-component phosphate product.
Description
Technical field
The present invention relates to a kind of antistatic agent composition.Particularly, the present invention relates to a kind of alkyl phosphate antistatic agent composition.
Technical background
Alkyl phosphate (salt) is a class function excellent anionic tensio-active agent, have antistatic, wetting, solubilising concurrently, clean, emulsification, dispersion, chelating, multiple function such as lubricated, and be easy to biological degradation, pungency is low, the thermostability height, thereby be widely used in industrial circles such as chemical fibre, weaving, printing and dyeing, plastics, papermaking, leather, household chemicals and electronics, often be used to prepare permeate agent, static inhibitor, fire retardant, defoamer, fatting agent, emulsifying agent, dispersion agent etc.During as static inhibitor, require product to sprawl, and effectively reduce surface resistivity, be beneficial to the dissipation of static charge on the application surface.For the occasion that has triboelectrification, except above-mentioned requirements, static inhibitor preferably also can have good lubricating property, can reduce surface resistivity like this, and when improving the static charge dissipation ability, the electrostatic of reducing friction produces.
The alkyl phosphate Industrial products comprise alkyl phosphate monoester, dibasic acid esters and composition thereof.Alkyl phosphate (salt) has been widely used in the industry such as weaving, papermaking, plastics as static inhibitor.
Alkyl phosphate (salt) is that neutralizing with alkali makes again by Fatty Alcohol(C12-C14 and C12-C18) and phosphoric acid esterification agent reaction.The auxiliary agent worker furthers investigate the esterification of above-mentioned Fatty Alcohol(C12-C14 and C12-C18) and Vanadium Pentoxide in FLAKES for many years.
As static inhibitor, the most frequently used Fatty Alcohol(C12-C14 and C12-C18) is C
12-18Monohydroxy-alcohol, phosphoric acid esterification agent then are Vanadium Pentoxide in FLAKES.For example:
CN1634938 (2005) (Shanghai Petrochemial Co Ltd, China Petrochemical Corp) discloses a kind of preparation method of alkyl phosphate salt;
CN1247192 (2000) (Huangma Chemical Group Co., Zhejiang) discloses isomery alcohol (ether) phosphate ester salt synthetic method;
CN 1080650 (1994) (Chen Jiaji etc.) discloses a kind of production method of static inhibitor.
Research conclusion in recent years shows that alkyl phosphate (salt) static inhibitor that is made by monohydroxy-alcohol has following feature:
1) alkyl phosphate monoester (salt) has antistatic property preferably, and alkylphosphonic acid carboxylic acid dibasic acid esters (salt) then has level and smooth preferably performance.
2) the finished product antistatic property of alkyl chain length is relatively poor, and the short finished product of alkyl chain then has antistatic property preferably.
3) change the parameters of phosphating reaction, for example the selection of monohydroxy-alcohol, ratio of components, feed way, temperature of reaction and time, hydrolysis time etc. can be regulated the ratio of monoesters and dibasic acid esters in the finished product within the specific limits.
Preparation dibasic alcohol phosphoric acid ester (salt) generally adopts phosphorus oxychloride and diol reaction to make, and for example CN1821252 has narrated a kind of phosphoric acid ester synthetic method.This type of dibasic alcohol phosphoric acid ester seldom is used as static inhibitor, and how as dispersion agent, fire retardant and water conditioner.
Behind alkyl phosphate (salt) finished product that inventor checking is made by monohydroxy-alcohol, when finding that low and ambient moisture is low at consumption, its antistatic property is difficult to satisfy service requirements.Particularly have in the application art of particular requirement at some, require static inhibitor to have static resistance and oilness concurrently such as spinning and spinning process, monohydroxy-alcohol phosphoric acid ester (salt) is difficult to take into account these functions.
Therefore, press for a kind of static resistance and oilness of having concurrently in this area, can satisfy the static inhibitor of spinning and spinning process requirement.
Summary of the invention
The inventor finds pleasantly surprisedly that by a large amount of tests it is composite to adopt monohydroxy-alcohol phosphoric acid ester (salt) and dibasic alcohol phosphoric acid ester (salt) to carry out, and can make the static inhibitor finished product that static resistance and lubricity significantly are better than corresponding one-component phosphoric acid ester (salt).
Antistatic agent composition of the present invention comprises the monohydroxy-alcohol phosphate mono-ester/diester component of general formula (1) expression and the single dibasic acid esters component of dibasic alcohol phosphoric acid ester of general formula (2) expression:
