Abstract
The invention relates to an alkyl siloxane and distearyl dimethyl ammonium chloride dual-treatment powder and a production process thereof, wherein the powder comprises the following components in parts by weight: 80-99.8 wt% of powder; distearyl dimethyl ammonium chloride 0.1%wt-10% wt; 0.1 wt% to 10 wt% of alkylsilane; the alkyl siloxane has the following structure (C)nH2n+1)aSi(OCmH2m+1)bWherein n represents an integer of 1 to 30, m represents an integer of 1 to 4, and X represents an integer of 1 to 20; a represents an integer of 1 to 3, b represents an integer of 1 to 3, and a + b is 4. The invention aims to greatly improve the addition of the distearyl dimethyl ammonium chloride compared with the prior art, so that the treated powder has strong hydrophobic capability and strong antistatic property while obtaining soft and smooth skin feel and easy spreadability.
Description
Technical Field
The invention relates to the technical field of powder treatment, in particular to double-treatment powder of alkyl siloxane and distearyl dimethyl ammonium chloride and a production process thereof.
Background
Distearyl dimethyl ammonium chloride has been widely used in daily chemical field such as shampoo and hair conditioner as a hair conditioner at present due to its unique soft and smooth hand feeling and positive charge characteristic. Meanwhile, distearyldimethylammonium chloride is also used in large quantities as a surfactant and an antistatic agent in other industrial fields.
Only mica treated by a wet process by Easthill corporation of korea is currently available (KR101279367B1), and the wet process is adopted in the powder treated by distearyldimethylammonium chloride as a powder surface treating agent, and the treated mica has soft and smooth skin feel and strong spreadability, but the powder treated by the method cannot obtain good hydrophobic property due to the surface activity of the distearyldimethylammonium chloride. And because the distearyldimethylammonium chloride spontaneously forms micelles in water, the micelle solution has extremely high viscosity even under very low concentration conditions, so that the method cannot obtain high additive amount of the treating agent (i.e., korean patent KR101279367B1, the additive amount is only 0.1 wt% of the total mass of the powder), which limits further improvement of the method on the product.
Disclosure of Invention
In view of the above problems in the prior art, the present invention aims to overcome the disadvantages in the prior art, and provides a double-treated powder of alkyl siloxane and distearyl dimethyl ammonium chloride and a production process thereof. The process adopts dry treatment, so that the addition amount of the distearyl dimethyl ammonium chloride is greatly improved compared with the prior art. The treated powder has soft and smooth skin feel and easy spreadability, and has strong hydrophobic ability and strong antistatic property.
The application provides an alkyl siloxane and distearyl dimethyl ammonium chloride dual processing powder, including following weight component:
80-99.8 wt% of powder;
distearyldimethylammonium chloride 0.1 wt% to 10 wt%;
0.1 wt% to 10 wt% of alkylsilane;
the alkyl siloxane has the following structure (C)nH2n+1)aSi(OCmH2m+1)bWherein n represents an integer of 1 to 30, m represents an integer of 1 to 4, and X represents an integer of 1 to 20; a represents an integer of 1 to 3, b represents an integer of 1 to 3, and a + b is 4.
Furthermore, the alkyl siloxane accounts for 0.5-10 wt%, and the distearyl dimethyl ammonium chloride accounts for 0.5-5 wt%.
Furthermore, the alkyl siloxane accounts for 1-5 wt%, and the distearyl dimethyl ammonium chloride accounts for 0.5-3 wt%.
Further, the powder includes, but is not limited to, inorganic powder or organic powder and combinations thereof.
Further, the inorganic powder is selected from one or more of synthetic mica, sericite, iron oxide, titanium oxide, ferric ferrocyanide, chromium green, manganese violet, kaolin, talc, barium sulfate, boron nitride, silicon dioxide, pearlescent pigment, metal pigment, zinc oxide, aluminum oxide, chromium oxide, glass and ultramarine blue.
Further, the organic powder is selected from one or more of organic color lake, high molecular polymer, wax powder, surfactant and metal soap.
A production process for double-treatment powder of alkyl siloxane and distearyl dimethyl ammonium chloride comprises a first process of the following steps:
adding distearyl dimethyl ammonium chloride and alkyl silane into the powder to be treated according to the design amount, mechanically mixing, heating to 40-150 ℃, keeping stirring, keeping the temperature for 0.5-8 hours, cooling, crushing and sieving.
In addition, the present application also provides another dry process:
a second process comprising the steps of:
mixing alkyl siloxane with powder to be treated, heating to 60-150 deg.C, holding the temperature for 0.5-4 hr, cooling to 0-100 deg.C, adding distearyl dimethyl ammonium chloride, stirring, heating to 60-150 deg.C, holding the temperature for 0.5-8 hr, cooling, pulverizing, and sieving.
To sum up, the application comprises the following beneficial technical effects:
1. the powder treated by the method has soft and smooth skin feel, easy spreadability and strong hydrophobic ability;
2. the distearyldimethylammonium chloride has positive charges, and the powder treated by the method has strong antistatic property while obtaining soft and smooth skin feel and easy spreadability;
3. the dispersibility of the powder treated by the method in a grease system is obviously enhanced, and the processing cost can be effectively reduced;
4. when the powder contains the coloring component, the compatibility of the powder and a medium and the color developing capability of the powder in the medium are improved due to the addition of the alkyl siloxane and the distearyl dimethyl ammonium chloride, and finally, a more bright appearance is obtained.
