What is Potassium stearate ?
Potassium stearate is also known as "potassium octadecanoate". White powder with crystalline structure. Soluble in hot water, insoluble in ether, chloroform and carbon disulfide. The aqueous solution appears to be alkaline and is phenolphthalein to litmus, and the ethanol solution may be slightly alkaline in comparison to phenolphthalein. It can be made by neutralizing the reaction of stearic acid with potassium hydroxide. It is widely used in the production detergents, surfactants and softeners. It can also be used in the creation of anti-slip products, graphene-modified adhesives for anti-caking, anti-caking, and waterproof coils.

2 . used to prepare a graphene-modified glue
The addition of graphene to the existing glue to alter 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 steps specific to HTML0 are as these:
Level 1: The graphene is mixed with n-butanol and toluene, ultrasonic dispersion is uniform. create 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 is brought down to 80°C. and ethylenediamine added to the reactor, stirred thoroughly and left to stand for a day to yield an unmodified graphene glue.
3. The preparation of composite anticaking agent to be used in food-grade potassium chloride
To reduce the risk of the risk of high blood pressure it is now permitted to add a portion of potassium chloride to substitute sodium chloride found in the salt. However, during the process that involves the storage and transportation of potassium chloride, the moisture contained in the product encourages recrystallization and dissolution of the powder's surface, which results in the formation of crystal bridges within the pores of the powder, and the crystals are combined with each other over time to develop. Huge mass. The weakening effect of fluidity affects the use of table salt. Thus, to prevent agglomeration, it is required to add an appropriate amount of anticaking agent to the production process.
The composite anti-caking agent used in food-grade potassium chloride is non-toxic, harmless in its color, odor, and colorlessness. It's composed of D-mannitol, potassium stearate, as well as calcium dihydrogen phosphate, wherein the specific gravity of D'mannitol potassium stearate, as well as dihydrogen phosphate are (1.25-5): (0.1-0.4): 1. The purity of the D-mannitol, potassium stearate, as well as calcium dihydrogen diphosphate, is food grade. Compared with the prior art this invention offers the benefits of being colorless and slightly white, doesn't alter the hue of the potassium chloride and is free of cyanide, is safe, and safe.
4. . The production of high-molecularly polyethylene polyester waterproof membrane
Polyethylene polypropylene has become a revolutionary substance that has come into use in recent years. Polypropylene is made up of polypropylene non-woven fabric as well as polyethylene, which is the raw material. It is composed of anti-aging agents and is created by high-tech, modern technology, and cutting-edge technology. The polymer polyethylene polypropylene composite water-proof roll material with an integrated layer has a substantial friction coefficient, exceptional stability, high mechanical strength small linear expansion coefficientand a broad temperature range for temperature adaptation, superior chemical resistance, weather resistance, and flexibility. This characteristic makes it an ideal green product for environmental protection in the 21st century. The method for making the high-molecular-molecular-molecular-polyethylene waterproof membrane includes the following steps:
Step 1: Weigh the raw materials according to the following weights by weight the following: 80-130 pieces of polyethylene resin. Ten to 20 parts of Talcum powder, 5-10 pieces of silica fume, 5-10 pieces from glass beads. 8-16 parts of potassium stearate. 8-18 pieces carboxylated latex, 10-20 pieces of anti-aging agents;
Step 2: Place silica fume, talcum powder along with potassium stearate as well as carboxylated latex of styrene and butadiene into high-speed mixer. Then, increase the temperature up to 70-80 deg C, stir at high speed for about 8 to 18 mins, and then raise the heat up to 95-100 deg Celsius. Following that, polyethylene resin and glass microbeads are added to the mixture is stirred up at a high speed for about 10-20 minutes for a mix;
Step 3: Insert the mixture in the feeding area create the extrusion and sheet of polypropylene, and then the plastic sheet entirely using the three-roller machine. Next, transfer this guide roller over to an tractor, cut off the edges, and then enter an electric coiler to make the final product.
Compared with the previous art beneficial effects of the invention are: synergistic effect by polyethylene resin, talc silicon fume, glass microbeads potassium stearate in the form of anti-aging and latex and any subsequent preparation steps, especially When the high-speed mixing takes place according to the order of the inputting of the raw material is particularly significant. In combination with the sequence of the present invention it is evident that the performance of the created high-molecular polyethylene and polypropylene waterproofing membrane is superior to the conventional high-performance waterproofing membrane.
