What is Potassium stearate

What's Potassium stearate ?

Potassium-stearate is also referred for its alias "potassium octadecanoate". White powder with crystalline structure. It is soluble in hot water and insoluble in ether, chloroform or carbon disulfide. The aqueous solutions are strongly alkaline to litmus or phenolphthalein The ethanol solution is slightly alkaline to phenolphthalein. It is obtained 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 utilized in the manufacture of anti-slip products, graphene-modified adhesives in addition to anti-caking and waterproof coils.

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

The new non-slip materials has solid wear resistance, as well as anti-slip performance. Furthermore, the raw substances in the formula are organic and easy to obtain. In the production process, the process is easy and straightforward to use, and the company has an extensive and efficient formula. Production materials include: short fiber, water-based glue, Zinc Oxide, Anti-Aging agent, photoinitiator (stearic acid), Potassium thermo-acetate, potassium stearate, coupling agent and carbon fiber, calculated according to the percentage of mass, this new non-slip material includes 5-10 parts of the length cord 0.5-5 portions of glue based on water, 3-7 parts zinc oxide, 5 pieces of antioxidant 2-8 slices of acids 1-5 parts of photoinitiator, Potassium Stearate 10-13 Parts, 1-8 parts of potassium-stearate, 3- 10 parts coupling agent, together with 0.5-10 pieces of carbon fiber.

2 . used to create a graphene-modified glue

Graphene is added to existing glue to modify its high-temperature resistance cement and enhance 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 steps specific to HTML0 are as like:

Level 1, the graphene is mixed with n-butanol and toluene, the ultrasonic dispersion becomes 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 is stopped, and the temperature drops to around 80 degrees Celsius. an ethylenediamine solution is added to reaction, thoroughly stirred for a few minutes, then allowed to sit for a full day, resulting in one graphene-modified gluing.

3. Preparation , mixing and preparation of composite anticaking agent to be used in potassium chloride that is food grade

In order to lessen the risk of hypertension, it is permitted to now add a small amount of potassium chloride to substitute sodium chloride in the edible salt. But, during the process transport and storage of potassium chloride, the moisture in the product facilitates the breakdown and recrystallization on the powder's surface. It forms crystal bridges in all the pores within the powder, and then the crystals join to form a crystal bridge over time. to develop. Huge mass. The weakness of fluidity affects the use of table salt. So, to ensure that there is no agglomeration vital to include a proper amount of anti-caking agent during the production process.

The composite anti-caking agent used in food grade potassium chloride is non-toxic, harmless and colorless. It also has no odor. It is made up of D-mannitol, potassium stearate, as well as calcium dihydrogen phosphate, wherein the particular gravity of D'mannitol potassium stearate, and dihydrogen phosphate is (1.25-5): (0.1-0.4) 1. The purity of the D-mannitol, potassium stearate, and calcium dihydrogen and phosphate is food grade. When compared with prior art this invention has the advantages of being completely colorless or white, it does not alter the whiteness of potassium chloride, is free of cyanide, is non-toxic, and is safe.

4 . The preparation of high-molecular polyethylene waterproof membranes made of polypropylene

Polyethylene Polypropylene, a new material which has been in use for a while. Polypropylene is a blend of polypropylene non-woven fabric as well as polyethylene is the principal raw material. It is composed of anti-aging agents and is made by the latest high-tech technology, and cutting-edge technology. The Polymer Polyethylene Polypropylene Composite waterproof roll material that has an integrated layer has significant friction coefficient, superb stability, high mechanical strength smaller linear expansion coefficient, broad temperatures, good chemical resistance, weather resistance and flexibility. The characteristic is an ideal sustainable product for protecting the environment in the 21st century. The preparation method of the waterproofing high-molecular polyethylene polypropylene membrane comprises of the following steps:

Step 1: Weigh the raw materials in accordance to the following parts of weight for the following quantities: 80-130 portions of polyethylene resin, 10-20 portions of Talcum powder; 5-10 parts of silica-based fume, 5-10 bits of glass beads and 8-16 pieces of potassium Stearate. 8-18 pieces of carboxylated butadiene latex, 10-20 components of the anti-aging ingredient;

Step 2: Mix silica fume, talcum powder in combination with potassium stearate and carboxylated latex of styrene and butadiene into high-speed mixer, raise the temperature up to 70-80 deg C, stir at high speed for 8 to 18 minutes, and then raise the heat to 95 to 100 degrees Celsius. Following that, polyethylene resin and glass microbeads are added, and the mixture is stirred at a high rate for 10 to 20 minutes in order in order to get a mixture

Step 3: Insert the mixture into the feeding area in order to extrude and create the polypropylene sheet and the plastic sheet fully using the three-roller machine, pass the guide roller on the tractor, trim the edgeand then go into the coiler to get the product.

Compared with the previous art beneficial results of the invention comprise the synergistic effect produced by polyethylene resin, talc, quartz microbeads, potassium stearate, carboxylated butadiene an anti-aging chemical, as well as the subsequent preparation steps. particularly when the high-speed mixing is carried out at a particular order, the method of introducing the raw materials is very vital. In conjunction with the sequence used in the present invention it is evident that the performance of the made high-molecular polyethylene polypropylene waterproofing membrane will be better than that of the typical high-performance waterproofing membrane.
