What is Potassium stearate

What exactly is Potassium Stearate ?

Potassium is also known as "potassium octadecanoate". White crystalline powder. Soluble in hot water, insoluble in chloroform, ether as well as carbon disulfide. The aqueous solution is strongly alkaline, ranging from litmus to phenolphthalein, and the ethanol solution can be slightly acidic to phenolphthalein. It is produced by neutralizing the reaction between stearic acid and potassium hydroxide. Commonly , it is used in the manufacturing in the production of surfactants, fiber softeners and so on. It is also used in the creation of anti-slip material, graphene modified glues for anti-caking, anti-caking, and waterproof coils.

1 . utilized to prepare a completely new kind made of material with no slip

The new non-slip material has outstanding wear resistance as well as anti-slip ability, and the materials in the formula are natural to purchase. When it comes to manufacturing, the method is simple and quick to perform, and the company has the largest and most convenient formula. The production materials are: long fibers of short cord, water-based glue zinc oxideand anti-aging substance, the photoinitiator, and stearic Acid. Potassium stearate, potassium coupled agent, carbon fiber. All of these are calculated according to the mass percentage. novel non-slip product includes 5-10 parts of the fiber, 0.5-5 percent of water-based glue. of zinc oxide 5 pieces of antioxidant, two to eight slices of stearic acids 1-5 pieces of photoinitiator, Potassium stearate 10-13 parts, 1-8 parts of potassium stearate 3-10 components of coupling as well as 0.5-10 part of carbon.

2. . used to create a graphene-modified glue

Graphene adds to the existing glue to alter the high-temperature resistant of the cement, and increase its adhesion. The material for preparing the paste is calculated by parts by weight: 12-30 parts of polyurethane, 15-30 parts of chloroprene rubber, 15-30 parts of polyacrylate, 2-12 parts of graphene, triallyl isocyanuric acid 0.8-1.6 parts of ester, 1-6 pieces of ethylenediamine, 2-10 parts of n-butanol, 2-8 pieces of toluene, 0.8-3 parts of potassium stearate, 2-8 parts of polyvinylpyrrolidone, N- 1-5 parts of phenyl-b-naphthylamine;

The specific steps are as the following:

Level 1: The graphene will be added to the n'butanol and toluene. The ultrasonic dispersion remains uniform, to create a mixed solution;

Step 2, adding polyurethane, chloroprene rubber, and polyacrylate into the reactor, the temperature is raised to 80-105 deg C, the reaction is 1-3 hours, and then the mixed solution A and triallyl isocyanurate in the first step The acid ester, potassium stearate, polyvinylpyrrolidone, and N-phenyl-b-naphthylamine are sequentially added to the reactor, the reaction temperature is adjusted to 150-360 deg C, and the reaction is carried out for 2-5 hours to obtain a mixture B;

In step 3, the reaction is stopped. the temperature is brought down to 80 degrees C. and ethylenediamine added to the reactor, which is stirred continuously for a few minutes, then allowed to sit for one day to obtain one graphene-modified gluing.

3. The preparation of composite anticaking agent to be used in food-grade potassium chloride

To lower the chance of having elevated blood pressure it is now possible to add a bit of potassium chloride to replace sodium chloride within the edible salt. But, during the process in the storage and transport of potassium chloride contained in the product promotes the recrystallization and dissolution of powder's surface. This creates a crystal bridge at each of the powder's pores and the crystals combine with each other as they continue to form. Huge mass. The weakening of fluidity affects its use in table salt. In order to stop the formation of agglomeration it is necessary to add an appropriate amount of anti-caking agent in the process of production.

The anti-caking compound used in food grade potassium chloride is non-toxic, harmless colored, and odorless. It is composed of D-mannitol, potassium stearate, and calcium dihydrogen phosphate. the specific gravity of D-mannitol potassium stearate, as well as dihydrogen phosphate are (1.25-5): (0.1-0.4): 1. The purity of the D-mannitol, potassium stearate, as well as calcium dihydrogen are food grade. As compared to prior art this invention has advantages of being colorless or lightly white, doesn't alter the whiteness of potassium chloride, does not contain cyanideand is therefore non-toxic and non-harmful.

4 . The production of high-molecular-polyethylene waterproof membrane of polypropylene

Polyethylene Polypropylene is an innovative material which has been in use for a while. Polypropylene is made of polypropylene non-woven fabrics and polyethylene is the principal raw material. It is made of anti-aging agents and is processed using the most advanced, high-tech technologyand innovative technology. The polymer polyethylene polypropylene composite waterproof roll material that has an integrated coating has a huge friction coefficient, excellent stability, high mechanical strength small linear expansion coefficient, wide temperature range of adaptation, outstanding chemical resistance, weather resistance and flexibility. The characteristic is an ideal green product for environmental protection in the 21st century. The process of making the waterproofing membrane comprises of the following steps:

Step 1: Weigh the raw materials according to the following percentages by weight in the range of 80-130 parts polyethylene resin. Also, 10-20 percent of Talcum powder; 5-10 parts of silica gas, 5-10 portions in glass beads. There are 8-16 pieces of potassium Stearate. 8-18 pieces of carboxylated butadiene latex, 10-20 components of the anti-aging agent;

Step 2: Place talcum powder, silica fume silica fume, potassium stearate, and carboxylated butadiene-styrene latex into a high-speed mixer, raise the temperature to 70-80 deg C. Stir the mixture at high speed for between 8 and 18 minutes, and then increase the heat until it reaches 95-100 degrees C. Then, glass microbead and polyethylene resin are added, and the mixture is stirred with a high speed for 10-20 minutes to form a mix.

Step 3: Put the mixture into the feeding area create the extrusion and sheet of polypropylene, and then the plastic sheet completely using the three-roller machine. Next, transfer the guide roller through the tractor, slice the edge, then go through the coiler to create the finished product.

Comparatively to the previously known techniques, the beneficial benefits of this invention are: synergistic effect by polyethylene resin, talc silica fume, glass microbeads potassium stearate, carboxylated butadiene anti-aging agent, latex and any subsequent preparation steps, particularly when the high-speed mixing is carried out by a sequence of introducing the raw materials is particularly important. When combined with the sequence of the invention, the performance of the developed high-molecularly polyethylene polypropylene waterproofing membrane exceeds that of the typical high-performance waterproofing membrane.
