What is Potassium stearate

What's Potassium stearate ?

Potassium stearate can also be referred to for its alias "potassium octadecanoate". White powder with crystalline structure. Soluble in hot water, insoluble in ether, chloroform and carbon disulfide. The solution that is aqueous is alkaline, ranging from litmus to phenolphthalein while the ethanol solution is slightly alkaline to phenolphthalein. It is produced by neutralizing the reaction of stearic acetic acid with potassium hydroxide. It is widely used in the production in the production of surfactants, fiber softeners and so on. It is also utilized in the fabrication of anti-slip materials, graphene -modified glues in addition to anti-caking and waterproof coils.

1 . This is used to create a novel kind in non-slip fabric

The new non-slip materials has high wear resistance and anti-slip performance. Additionally, the raw components in the formula are easy to acquire. It is produced using the method is simple and easy to operate, and the manufacturer provides an extensive and efficient formula. Production materials include: long fibers of short cord, water-based glue zinc oxide, anti-aging agent photoinitiator, stearic acids, Potassium thermo-sulfate, potassium in combination with coupling agent and carbon fiber. Based on the percentage of mass. This new non-slip material Including 5-10 parts of the shorter cords, 0.5-5 part of water-based glue. Three to seven pieces of zinc oxide 1-5 antioxidant pieces, 2-8 slices , stearic acid, 1-5 parts of photoinitiator Potassium Stearate 10-13 parts 1-8 parts of potassium-stearate, three to ten parts of coupling agents, also 0.5-10 elements of carbon.

2 . used to prepare a graphene-modified glue

Graphene can be added to the existing glue to modify the high-temperature resistance of 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 specific steps are as like:

Level 1, the graphene is mixed with n-butanol and toluene. Ultrasonic dispersion is uniform to get a mixed mix solution 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: Above reaction ceases, and the temperature is reduced to around 80 degrees Celsius. ethylenediamine is added into the reaction, thoroughly stirred for a few minutes, then allowed to sit for a full day, resulting in an improved graphene glue.

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

In order to reduce the risk of increased blood pressure it's permitted to now add a small amount of potassium chloride that replaces sodium chloride that is present in the salt. But, during the process of transportation and storage of potassium chloride, the moisture contained in the product encourages recrystallization and dissolution of the powder surface, thereby forming crystal bridges in the pores of the powder and the crystals combine with one another over time to develop. Huge mass. The weakening of fluidity impacts its usage in table salt. In order to prevent agglomeration, its important to add a sufficient amount of anticaking agent throughout the production process.

The anticaking additive used in food grade potassium chloride is safe, harmless as well as colorless and odorless. It is made up of D-mannitol, potassium stearate, and calcium dihydrogen phosphate. the specific gravity of D'mannitol potassium stearate, as well as dihydrogen phosphate is (1.25-5): (0.1-0.4): 1. The purity of D-mannitol, potassium stearate, as well as calcium dihydrogen are food grade. When compared with prior art this invention offers the benefits of being colorless and slightly white, and does not alter the colour of potassium chloride. It also is free of cyanide, is non-toxic, and is safe.

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

Polyethylene Polypropylene is an innovative material that has recently been utilized. Polypropylene is a blend of polyester non-woven fabric and polyethylene as the primary raw material. It is composed of anti-aging substances and manufactured using high-tech, advanced technologies and advanced technology. The polymer polyethylene polypropylene waterproof roll material with an integrated layer boasts a significant friction coefficient, excellent durability, stability, high mechanical strength as well as a very low linear expansion coefficient, large temperature adaptability, great chemical resistance, weather resistance, and flexibility. This characteristic makes it an ideal eco-friendly product to protect the environment in the new century. The preparation method of the high-molecular Polyethylene polypropylene waterproofing membrane comprises the following steps:

Step 1: Measure the raw materials in accordance to the following parts of weight the following: 80-130 pieces of polyethylene resin, 10-20 pieces of clay powder, 5-10 components of silica fume, 5-10 parts from glass beads. 8-16 parts of potassium stearate. 8-18 pieces, carboxylated, styrenebutadiene latex, 10-20 pieces of anti-aging agents;

Step 2: Place talcum powder, silica fume as well as potassium stearate and carboxylated polystyrene-butadiene (latex) high-speed mixer. Set temperatures to 70-80 degrees C. Stir at a rapid speed for 8 to 18 minutes, and then increase the heat by 95-100 degrees Celsius. After that, a glass microbeads made of polyethylene are added to the mixture is stirred with a high speed for 10-20 mins in order to get a mixture

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

When compared with earlier art positive benefits of this invention are the synergistic effects of materials such as polyethylene resin silica-based fumes and glass microbeads potassium stearate the latex, anti-aging substance, and subsequent preparation steps, particularly when the high-speed mixing takes place with the proper order of input of the raw material is particularly crucial. In conjunction with the sequence of this invention the performance of the created high-molecular polyethylene and polypropylene waterproofing membrane surpasses that of traditional waterproofing membranes that are high-performance.
