What is Potassium stearate

What is Potassium stearate ?

Potassium Stearate is also referred to as "potassium octadecanoate". White crystalline powder. Soluble in hot water, insoluble in ether, chloroform or carbon disulfide. The aqueous solution tends to be alkaline, ranging from litmus to phenolphthalein and the ethanol solution is slightly alkaline to phenolphthalein. It can be obtained by neutralizing the reactions of stearic and potassium hydroxide. It is often used in manufacturing of fiber softeners and surfactants. It is also utilized in the fabrication of anti-slip glues, graphene-modified gluing as well as anti-caking agents and waterproof coils.

1. . Used to make a new type made of material with no slip

The latest non-slip material is designed to have solid wear resistance, as well as anti-slip performance. Additionally, the raw ingredients used in the formulation are naturally available to purchase. For the production process, the process is easy and quick to perform, and the manufacturer uses a large and convenient material formula. Production materials include: the short-fiber, water-based adhesive zinc oxideas well as anti-aging agents, stearic acid, photoinitiator, Potassium thermo-stearate, potassium stearate coupled agent, carbon fiber. Based on the mass percentage. This non-slip new material comprises 5-10 pieces of small cord, 0.5-5 percent of water-based glue. of zinc oxide 1-5 antioxidant pieces, 2-8 slices of the stearic acids, 1-5 parts of photoinitiator, Potassium stearate 10-13 parts, 1-8 parts potassium stearate 3-10 parts of coupling agent, plus 0.5-10 part of carbon.

2. . utilized to make graphene-modified glue

Graphene is added to existing glue to modify the high-temperature resistance 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 below:

Level 1: The graphene is added to n'butanol and toluene, the ultrasonic dispersion is uniform, to produce 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;

Step 3, the above reaction ceases, and the temperature is reduced to around 80 degrees Celsius. ethylenediamine is added into the reactor, and stirred evenly for a few minutes, then allowed to sit for one day before obtaining the graphene-modified glue.

3. Preparation of a composite anticaking agent to be used in potassium chloride food grade

To minimize the possibility of elevated blood pressure it's currently permitted to add a little of potassium chloride , which replaces sodium chloride that is present in the salt. In the process that involves the storage and transportation of potassium chloride in the product promotes the decomposition and recrystallization powder surface, thereby forming crystal bridges in its pores and the crystals are combined with one another over time to form. Huge mass. The weakening in fluidity can affect its usage in table salt. In order to stop the formation of agglomeration it is crucial to add the correct amount of anticaking agent throughout the production process.

The anticaking additive used in food grade potassium chloride is non-toxic harmless non-toxic, colorless, and odorless. It is composed of D-mannitol, potassium stearate, and calcium dihydrogen phosphate. the specific gravity of D-mannitol potassium stearate and dihydrogen phosphate is (1.25-5): (0.1-0.4): 1. The purity of D-mannitols, potassium stearates, as well as calcium dihydrogen diphosphate, is food grade. As compared to prior art, the invention has the advantages of being colourless or slightly white, does NOT alter the whiteness of potassium chloride. does not contain cyanide, is not toxic, and harmless.

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

Polyethylene Polypropylene is a novel material in recent times. Polypropylene is composed of non-woven polypropylene fabric and polyethylene as the primary raw material. It is made of anti-aging agents and is processed using the most advanced, high-tech technology, and new technology. The Polypropylene polyethylene composite waterproof roll material with an integrated layer offers a large friction coefficients, high quality, durability as well as a very low linear expansion coefficients, a large temperature adaptability range, exceptional weather resistance, chemical resistance and flexibility. This makes it an ideal environmentally-friendly protection product for the new century. The procedure for the preparation of the high-molecular polyethylene polypropylene waterproofing membrane is based on the following steps:

Step 1: Weigh the raw materials according to the following percentages by weight including 80-130 ppm of polyethylene resin. Ten to 20 parts of talcum powder, 5-10 parts of silica fume. 5-10 parts in glass beads. There are 8-16 pieces of potassium stearate. 8-18 pieces of carboxylated styrene butadiene latex, 10-20 pieces of the anti-aging agent

Step 2: Pour silica fume, talcum powder the potassium stearate, silica fume and carboxylated latex of styrene and butadiene into high-speed mixer. Adjust the temperature up to 70-80 deg C, mix at a high speed for between 8 and 18 minutes, and then increase the heat until it reaches 95-100 degrees C. Following that, glass microbeads and polyethylene resin are added, and the mixture is stirred at a rapid rate for 10 to 20 minutes in order to make a blend;

Step 3 : Put the mix into the feeding space create the extrusion and Polypropylene sheet, as well as the plastic sheet completely with the 3-roller machine. Pass this guide roller over to it, cut the edges, and then enter the coiler to get the finished product.

Comparatively to the earlier art beneficial results of the invention comprise an effect of synergy between materials such as polyethylene resin silica-based fumes and glass microbeads potassium stearate and carboxylated styrene butad anti-aging agent, latex as well as the subsequent preparation steps. especially When the high-speed mixing process is being carried out at a particular order, the method of introducing the raw materials can be crucial. Together with the sequence of the invention, the performance of the made high-molecular polyethylene polypropylene waterproofing membrane far exceeds that of the typical high-performance waterproofing membrane.
