CN104592791A - Method for preparing silicon treatment talcum powder - Google Patents

Abstract

The invention discloses a method for preparing silicon treatment talcum powder. The method comprises the following steps: (1) adding 0.5-1g of stearic acid into 90g of 75 percent acetic acid solution for stirring 10 minutes until the solution is uniformly stirred; (2) dripping a proper amount of sodium hydroxide solution, slowly adding the solution so that the pH value is controlled to be between 8 and 9, and further stirring; (3) adding 10g of talcum powder, continuously stirring, heating to the temperature of 90 DEG C, and stirring for 60 minutes; and (4) washing, filtering, drying, and scattering, thereby obtaining the product. Aiming at the defects in the prior art, the modified product produced by a wet process has excellent hydrophobic oleophylic performance, the activating rate is over 98 percent, and the product can be inter-miscible with an organic phase, is good in dispersion effect and can be widely applied to oil-based products.

Description

The talcous preparation method of a kind of silicon process

Technical field

The present invention relates to talcous preparation method, particularly relate to the talcous preparation method of a kind of silicon process.

Background technology

Talcum powder fills organic polymer material as filler, the rigidity of goods, dimensional stability, oilness can be improved, high temperature creep can be prevented, reduce the wearing and tearing to forming machine, can make polymkeric substance while improving hardness and creep resistance by filling, the heat shock resistance intensity of polymkeric substance also can be made to improve, the molding shrinkage of plastics, the bending elastic modulus of goods and tensile yield strength can be improved.Along with the development of modern industry, increasing to talcous demand.But the defects such as existing product exists hydrophobic oleophilic oil poor performance, and activation rate is low, have impact on the application of talcous further genralrlization.

Summary of the invention

Invent problem to be solved to be: provide a kind of silicon process talcous preparation method, the hydrophobic oleophilic oil performance that its tool is excellent, activation rate is high, can dissolve each other with organic phase, the better feature of dispersion effect.

Technical solution problem of the present invention adopts following technical scheme:

The talcous preparation method of a kind of silicon process, comprises the following steps:

1) acetic acid (concentration 75%) solution that the stearic acid, getting 0.5-1 gram puts into 90 grams stirs 10min to stirring;

2), drip appropriate sodium hydroxide solution, slowly add, make its pH value control between 8-9, do not stop to stir;

3), add 10 grams of talcum powder, do not stop to stir and be heated to 90 degree, stir 60 minutes;

4), wash, filter, dry, break up and obtain goods.

The invention has the beneficial effects as follows: the present invention is directed to the deficiencies in the prior art, the modified product adopting wet production to obtain has excellent hydrophobic oleophilic oil performance, and activation rate reaches more than 98%, can dissolve each other with organic phase, dispersion effect is better, can be widely used in oil-based products.

Embodiment

The technique means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, setting forth the present invention further below.

The talcous preparation method of a kind of silicon process, comprises the following steps:

1) acetic acid (concentration 75%) solution that the stearic acid, getting 0.5-1 gram puts into 90 grams stirs 10min to stirring;

2), drip appropriate sodium hydroxide solution, slowly add, make its pH value control between 8-9, do not stop to stir;

3), add 10 grams of talcum powder, do not stop to stir and be heated to 90 degree, stir 60 minutes;

4), wash, filter, dry, break up and obtain goods.

The present invention proposes the talcous preparation method of a kind of silicon process.The present invention is directed to the defect of the prior art mentioned in background technology, in conjunction with prior art, wet production is adopted to obtain modified product, described modified product has excellent hydrophobic oleophilic oil performance, activation rate reaches more than 98%, can dissolve each other with organic phase, dispersion effect is better, can be widely used in oil-based products.

The above; be only the present invention's preferably embodiment; but protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to according to technical scheme of the present invention and inventive concept thereof and replace or change, all should be encompassed within protection scope of the present invention.
