What is Potassium stearate

What's Potassium Stearate ?

Potassium stearate can also be referred to in the form of "potassium octadecanoate". White crystalline powder. It is soluble in hot water and insoluble in ether, chloroform or carbon disulfide. The solution that is aqueous is alkaline and is phenolphthalein to litmus and the ethanol solution somewhat alkaline to the phenolphthalein. It is obtained by neutralizing the reaction of stearic acids with potassium hydroxide. It is widely used in the production detergents, surfactants and softeners. It can also be utilized in the fabrication of anti-slip materials, graphene -modified glues as well as anti-caking agents and waterproof coils.

1. . used to prepare a new kind for non-slip materials

The brand new non-slip product has solid wear resistance, as well as anti-slip ability, and the ingredients in the formula are naturally available to purchase. In the manufacturing process, the process is easy and simple to use, and the company has an extensive and easy-to-use material formula. Production materials include: short fiber, water-based glue, zinc oxide, antioxidant agent photoinitiator, stearic acids, Potassium thermo-sulfate, potassium stearate, coupling agent and carbon fiber. Measured according to the mass percentage, this novel non-slip product includes 5-10 pieces of small cord, 0.5-5 parts of water-based glue, 3-7 pieces of zinc oxide 1-5 pieces of antioxidant, two to eight slices of stearic acid 1-5 components of photoinitiator Potassium Stearate 10-13 Parts, 1-8 pieces of potassium stearate three to ten parts of coupling agents, along with 0.5-10 part of carbon.

2 . It is used to make a graphene-modified glue

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

Level 1, the graphene is added to n'butanol and toluene. Ultrasonic dispersion is uniform. make a mixed mixture 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;

In step 3, the reaction is stopped. the temperature drops to around 80 degrees Celsius. adding ethylenediamine to the reaction, thoroughly stirred and left to stand for a full day, resulting in an unmodified graphene glue.

3. Preparation of a composite anti-caking agent to be used in potassium chloride food grade

To reduce the possibility of high blood pressure, it is permitted to now add a small amount of potassium chloride in order to replace sodium chloride within the edible salt. However, in the process of transportation and storage of potassium chloride, the moisture contained in the product can cause breakdown and recrystallization on the material's surface, creating crystal bridges at the pores of the powder, and the crystals are combined with one another over time to form. Huge mass. The weakness of fluidity affects its use in table salt. In order to prevent agglomeration, its vital to include a proper amount of anticaking agent throughout the production process.

The anticaking additive used in food grade potassium chloride is non-toxic harmless as well as colorless and odorless. It's comprised of D'mannitol along with 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 the D-mannitoland potassium stearate and calcium dihydrogen and phosphate is food grade. Comparatively to prior art the invention has advantages of being colorless or lightly white, is not able to alter the whiteness of potassium chloride. is free of cyanide, and is non-toxic and safe.

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

Polyethylene Polypropylene is a novel material used in recent years. Polypropylene is a blend of polypropylene non-woven fabrics and polyethylene as its primary raw material. It is made of anti-aging ingredients and added by high-tech technology, and cutting-edge technology. The polymer polyethylene and polypropylene composite waterproof roll material that has an integrated coating has a huge friction coefficient, outstanding stability, high mechanical strength as well as a very low linear expansion coefficient, extensive temperatures, good chemical resistance, weather resistance, and flexibility. This makes it a perfect environmentally-friendly protection product for the new century. The process for making the high-molecular polyethylene polypropylene waterproofing membrane comprises of the following steps:

Step 1: Weigh the raw materials using the following weights by weight that is 80-130 parts of polyethylene resin, 10-20 pieces of the talcum powder, 5-10 portions of silica fume; 5-10 parts of glass beads, and 8-16 parts of potassium Stearate. 8-18 pieces made of carboxylated styrene-butad latex, 10-20 pieces of the anti-aging substance;

Step 2: Pour talcum powder, silica fume potassium stearate, carboxylated styrene-butadiene latex into a high-speed mixer. Set the temperature up to 70-80 deg C, mix at a high speed for about 8 to 18 mins, 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 on high speed for about 10-20 minutes for a mix;

Step 3: Add the mixture into the feeding area to extrude the sheet of polypropylene and the plastic sheet in the complete manner using the three roller machine. Once the machine is in place, it will pass the guide roller through your tractor, then cut the edges, then move into the coiler to create the product.

In comparison with the earlier art beneficial effects of the invention are that it creates synergistic effects by Polyethylene Resin, Talc, silica fumes, glass microbeads, potassium stearate an anti-aging chemical, and subsequent preparation steps, especially When the high-speed mixing process is being carried out using a specific order for the input of the raw materials is extremely crucial. In combination with the sequence of the invention in the present invention, the performance of created high-molecular polyethylene and polypropylene waterproofing membrane will be better than that of the traditional high-performance waterproofing membrane.
