What is Potassium stearate

What is Potassium stearate ?

Potassium stearate can also be referred to as "potassium octadecanoate". White powder with crystalline structure. It is soluble in hot water and insoluble in ether, chloroform and carbon disulfide. The aqueous solution is strongly alkaline to litmus or phenolphthalein, and the ethanol solution will be slightly alkaline to that of phenolphthalein. It is produced by neutralizing the reaction of stearic acid with potassium hydroxide. Commonly used in the manufacture of softeners for fibers and other surfactants. It can also be used in the creation of anti-slip materials, graphene-modified glues, anti-caking agents, and waterproof coils.

1 . used to prepare a new type of slip-resistant material

The brand new non-slip product has strong wear resistance and anti-slip performance. The raw ingredients in the formula are organic and easy to obtain. In the process of making it, the process is easy and user-friendly and the company has a large and convenient material formula. The production materials are: short fiber, water-based glue, zinc oxide, anti-aging agents, stearic acid, photoinitiator, Potassium thermo-sulfate, potassium stearate in combination with coupling agent and carbon fiber. All of these are calculated according to the mass percentage. This new non-slip materials includes 5-10 parts of fiber, 0.5-5 parts of water-based glue, 3-7 pieces of zinc oxide 1-5 pieces of antioxidant 2- 8 slices of Stearic acids 1-5 components of photoinitiator Potassium Stearate 10-13 Parts, 1-8 parts of potassium stearate, 3-10 pieces of coupling agent along with 0.5-10 parts of carbon fiber.

2 . used to prepare graphene-modified glue

The addition of graphene to the existing glue to alter its resistance to high temperatures 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. Ultrasonic dispersion is uniform, to achieve a mixed solutions A;

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 previous reaction ceases, and the temperature drops to 80 deg C, an ethylenediamine solution is added to reaction, thoroughly stirred, and allowed to stand for a day to yield graphene-modified adhesive.

3. Preparation of composite anti-caking agent for use in food-grade potassium chloride

In order to reduce the possibility of higher blood pressure it is currently allowed to add some of potassium chloride in order to replace sodium chloride found in the salt. However, in the process in the storage and transport of potassium chloride, the moisture in the product promotes the decomposition and recrystallization porous surface of the powder, resulting in a crystal bridge at its pores, and the crystals combine in time to develop. Huge mass. The weakening effect of fluidity affects its use in table salt. Thus, to stop the formation of agglomeration it is necessary to add an appropriate amount of anticaking agent in the production process.

The anticaking agent, a compound, used in food-grade potassium chloride is non-toxic harmless as well as colorless and odorless. It is composed of D-mannitol in combination with potassium stearate as well as calcium dihydrogen phosphate, wherein the specific gravity of D-mannitol potassium stearate, as well as dihydrogenphosphate are (1.25-5): (0.1-0.4): 1. The purity of D-mannitols, potassium stearates, as well as calcium dihydrogen are food grade. In comparison to the prior art, the invention has the advantages of colorless or slightly white, does NOT alter the hue of the potassium chloride and does not contain cyanide, and is non-toxic and non-harmful.

4 . The process of making high-molecular polyethylene waterproof membrane made from polypropylene

Polyethylene Polypropylene is a novel material in recent times. Polypropylene is made of polyester non-woven fabric and polyethylene as the basic raw material. It is composed of anti-aging agents and is made by the latest high-tech technologyand innovation. The polymer polyethylene polypropylene composite water-proof roll material that has an integrated coating has a huge friction coefficient, superb quality, durability small linear expansion coefficient, wide temperature adaptability range, exceptional chemical resistance, weather resistance and flexibility. This is a desirable environmentally friendly product for the new century. The procedure of making the high-molecular Polyethylene polypropylene waterproofing membrane comprises the following steps:

Step 1: Measure the raw materials in accordance with the following weight percentages in the range of 80-130 parts polyethylene resin, 10-20 portions of talcum powder. 5-10 parts of silica fume, 5-10 parts in glass beads. There are 8-16 parts of potassium Stearate. 8-18 pieces of carboxylated styrene-butadiene latex, 10-20 portions of the anti-aging ingredient;

Step 2: Pour talcum powder, silica fume the potassium stearate, silica fume and carboxylated styrene-butadiene latex into a high-speed mixer, raise the temperature up to 70-80 deg C, and stir at a high speed for 8-18 min, and then increase the heat by 95-100 degrees Celsius. After that, a polyethylene resin and glass microbeads are added to the mixture is stirred on high speed for 10-20 minutes to create a mixture;

Step 3 : Put the mix into the feeding space Extrude and then form the sheet of polypropylene, and then the plastic sheet completely using the three-roller machine. After that, you can pass the guide roller through it, cut the edges, then enter the coiler to create the final product.

In comparison to the previous art advantageous effects of this invention include the synergistic effects of Polyethylene Resin, Talc, silica fume, glass microbeads, potassium stearate and carboxylated styrene butad latex, anti-aging agent, and subsequent preparation processes, especially when high-speed mixing is performed and the sequence of entering the raw materials can be important. In conjunction with the sequence of the present invention in the present invention, the performance of made high-molecular polyethylene polypropylene waterproofing membrane can be superior that of the typical high-performance waterproofing membrane.
