What is Potassium stearate

What exactly is Potassium Stearate ?

Potassium Stearate is also referred to for its alias "potassium octadecanoate". White crystalline powder. Soluble in hot water, insoluble in ether, chloroform as well as carbon disulfide. The aqueous solution tends to be alkaline in comparison to phenolphthalein or litmus and the ethanol solution will be slightly alkaline to that of phenolphthalein. It can be obtained by neutralizing the reaction between stearic acid and potassium hydroxide. Commonly used in the manufacture of surfactants and fiber softeners. It is also utilized in the manufacture of anti-slip glues, graphene-modified gluing in addition to anti-caking and waterproof coils.

1 . The 1 is used to design a different type of non-slip material

The new non-slip material has strong wear resistance and anti-slip performance. The raw materials in the formula are naturally available to purchase. For the production process, the method is simple and user-friendly and the manufacturer uses an extensive and efficient material formula. Materials used in production include long fibers of short cord, water-based glue, zinc oxide, antioxidant agents, stearic acid, photoinitiator, Potassium stearate, potassium coupled agent, carbon fiber. Calculated based on its mass percentage. new non-slip materials includes 5-10 parts of the fiber, 0.5-5 elements of water-based adhesive, 3-7 pieces of zinc oxide 1-5 pieces of antioxidant, 2-8 slices of the stearic acids, 1-5 parts of photoinitiator Potassium Stearate 10-13 Parts, 1-8 parts of potassium stearate 3-10 pieces of coupling agent plus 0.5-10 portions of carbon.

2. . Used to prepare graphene-modified glue

Graphene adds to the existing glue to alter the high-temperature resistance of 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 like:

Level 1, the graphene is mixed with n-butanol and toluene. 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 previous reaction is stopped. it is then lowered to 80°C. in the step 3, ethylenediamine enters the reactor, and stirred evenly and left to stand for a full day, resulting in one graphene-modified gluing.

3. The preparation of composite anticaking agent for use in potassium chloride food grade

To decrease the risk of hypertension, it's currently allowed to add some of potassium chloride in order to replace sodium chloride in the food salt. However, in the process of storage and transportation of potassium chloride contained in the salt promotes recrystallization and dissolution of the powder's surface. This results in a crystal bridge at these pores, and the crystals then combine with one another over time to form. Huge mass. The weakening in fluidity can affect its usage in table salt. In order to ensure that there is no agglomeration required to add an appropriate quantity of anti-caking agents during the production process.

The anti-caking compound used in food grade potassium chloride is non-toxic, harmless that is colorless, odorless, and colorless. It is comprised of D-mannitol along with potassium stearate and calcium dihydrogen phosphate. the specific gravity of D-mannitol potassium stearate, and dihydrogen phosphate are (1.25-5): (0.1-0.4) 1. The purity of D-mannitols, potassium stearates, as well as calcium dihydrogen are food grade. Comparatively to prior art the invention has advantages of being colourless or slightly white, doesn't alter the whiteness of potassium chloride. does not contain cyanide, is not toxic, and is safe.

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

Polyethylene polypropylene is a new 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 with anti-aging components and manufactured using high-tech, advanced technology, and cutting-edge technology. The polymer polyethylene polypropylene composite waterproof roll material that has an integrated coating has a huge friction coefficient, outstanding quality, durability, small linear expansion coefficient, wide temperature range of temperature adaptation, superb chemical resistance, weather resistance, and flexibility. This characteristic makes it an ideal environmentally-friendly protection product for the new century. The process for making the high-molecular Polyethylene polypropylene waterproofing membrane is as follows:

Step 1: Weigh the raw materials in accordance to the following percentages by weight that is 80-130 parts of polyethylene resin, 10-20 parts of talcum powder. 5-10 parts of silica gas, 5-10 portions from glass beads. 8-16 parts of potassium stearate. 8-18 pieces made of carboxylated styrene-butad latex, 10-20 portions of the anti-aging agent;

Step 2: Put silica fume, talcum powder along with potassium stearate as well as carboxylated styrene butadiene latex in a high-speed mixer. Set the temperature from 70 to 80 degrees C, stir at high speed for 8 to 18 minutes, and then increase the heat to 95-100 degrees Celsius. Following that, glass microbead and polyethylene resin are added and the mixture is stirred on high rate for 10 to 20 minutes in order for a mix;

Step 3: Insert the mixture into the feeding area Extrude and then form the sheet of polypropylene, and then the plastic sheet completely with the help of the three-roller machine. Next, transfer the guide roller on the tractor, trim the edges and then insert the coiler to create the finished product.

Comparatively to the conventional methods, beneficial effects of this invention include the synergistic effects of materials such as polyethylene resin, silicon fume, glass microbeads, potassium stearate and carboxylated styrene butad latex, anti-aging agents, and further preparation steps, especially When the high-speed mixing occurs and the sequence of entering the raw materials is very crucial. In conjunction with the sequence of the present invention it is evident that the performance of the developed high-molecularly polyethylene polypropylene waterproofing membrane is superior to that of the high-performance membranes for waterproofing.
