What is Potassium Stearate ?
Potassium stearate may also be referred in the form of "potassium octadecanoate". White crystalline powder. Soluble in hot water, insoluble in ether, chloroform as well as carbon disulfide. The aqueous solution is alkaline, ranging from litmus to phenolphthalein and the ethanol solution has a slight alkaline form to phenolphthalein. It is obtained by neutralizing the reaction of stearic Acid with potassium hydroxide. Commonly used in the manufacture of surfactants and fiber softeners. It can also be used in the production of anti-slip products, graphene-modified adhesives for anti-caking, anti-caking, and waterproof coils.

When it comes to manufacturing, the method is simple and quick to perform, and the producer has a vast and user-friendly material formula. Production materials include: long fibers of short cord, water-based glue, zinc oxideand anti-aging substance, stearic acid, photoinitiator, Potassium thermo-acetate, potassium stearate in combination with coupling agent and carbon fiber. The fiber is calculated based on its mass percentage. new non-slip material includes 5-10 parts of shorter cords, 0.5-5 three parts water-based glue. zinc oxide 1-5 parts of antioxidant 2-8 slices , stearic acid 1-5 components of photoinitiator, Potassium Stearate 10-13 Parts, 1-8 parts potassium stearate, 3-10 parts of coupling agent together with 0.5-10 elements of carbon.
2. . This is used to prepare a graphene modified glue
Graphene can be added to the existing glue to alter its resistance to high temperatures cement and improve 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 the following:
Level 1, the graphene is added to n-butanol and toluene, the ultrasonic dispersion is uniform, to obtain a mixed 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;
In step 3, the reaction ceases, and it is then lowered to 80°C. ethylenediamine is added into the reactor, which is stirred continuously and then left to stand for one day before obtaining the graphene modified glue.
3. The preparation of composite anticaking agent for use in food-grade potassium chloride
To minimize the chance of having hypertension, it's now permitted to add a portion of potassium chloride , which replaces sodium chloride in the food salt. In the process that involves the storage and transportation of potassium chloride, the moisture contained in the product facilitates the recrystallization and dissolution of the powder's surface, which results in the formation of crystal bridges in porous areas of powder, and crystals are then bonded to form a crystal bridge over time. to form. Huge mass. The weakening of fluidity impacts the use of table salt. In order to stop the formation of agglomeration it is vital to include a proper amount of anticaking agent to the process of production.
The anticaking additive used in food grade potassium chloride is safe, harmless, colorless, and odorless. It is made up of D-mannitol, potassium stearate, as well as calcium dihydrogen phosphate. the specific gravity of D'mannitol, potassium stearate, and dihydrogenphosphate are (1.25-5): (0.1-0.4): 1. The purity of D-mannitol, potassium stearate, and calcium dihydrogen is food grade. Comparatively to prior art this invention offers the advantages of being colourless or slightly white, doesn't alter the hue of the potassium chloride and does not contain cyanide, is non-toxic, and non-harmful.
4 . The process of preparing high-molecular Polyethylene polyester waterproof membrane
Polyethylene polypropylene is a new material used in recent years. Polypropylene is made up of polypropylene non-woven fabrics and polyethylene as the basic raw material. It is made of anti-aging compounds and manufactured using high-tech, advanced technology, and new technology. The polyester polypropylene water-proof roll material with an integrated layer offers a large friction coefficient, excellent durability, stability, high mechanical strength Small linear expansion coefficientand a broad temperature adaptability range, exceptional chemical resistance, weather resistance and elasticity. It is a great green product for environmental protection in the current century. The procedure of making the waterproofing of high-molecular polyethylene membrane is as follows:
Step 1: Measure the raw materials in accordance with the following parts of weight including 80-130 ppm of polyethylene resin. 10-20 parts of the talcum powder, 5-10 portions of silica fume. Five to ten parts of glass beads, and 8-16 pieces of potassium Stearate. 8-18 pieces carboxylated latex, 10-20 parts from the anti-aging agent.
Step 2: Put talcum powder, silica fume silica fume, potassium stearate, and carboxylated styrenebutadiene latex into high-speed mixer. Turn up temperatures to 70-80 degrees C. Stir the mixture at high speed for about 8 to 18 mins, and then raise the heat to 95 to 100 deg C. Following that, glass microbeads made of polyethylene are added and the mixture is stirred at a high speed for about 10-20 minutes to obtain a combination;
Step 3: Place the mixture in the feeding area to extrude the sheet of polypropylene and the plastic sheet completely by the three-roller machine. Pass the guide roller onto the tractor, cut the edgeand then go into the coiler to obtain the final product.
In comparison to the existing art positive effects of this invention include: synergistic effect by plastic resins, such as talc silica , glass microbeads potassium stearate and carboxylated styrene butad anti-aging agent, latex and subsequent preparation steps, especially When the high-speed mixing takes place by a sequence of introducing the raw materials is especially crucial. In conjunction with the sequence of the present invention it is evident that the performance of the manufactured high-molecular ethylene polypropylene waterproofing membrane is superior to traditional waterproofing membranes that are high-performance.
