What is Potassium stearate
What's Potassium stearate ?
Potassium stearate may also be referred for its alias "potassium octadecanoate". White crystalline powder. It is soluble in hot water and insoluble in ether, chloroform or carbon disulfide. The aqueous solution tends to be alkaline, ranging from litmus to phenolphthalein and the ethanol mixture can be slightly acidic to phenolphthalein. It can be made by neutralizing the reaction of stearic acid with potassium hydroxide. It is commonly used in the production in the production of surfactants, fiber softeners and so on. It can also be used to create anti-slip substances, graphene-modified glues in addition to anti-caking and waterproof coils.
1 . This is used to create a novel kind of slip-resistant material
The new non-slip materials has an excellent wear resistance and anti-slip performance, and the raw components in the formula are readily available for purchase. In the production process, the procedure is easy and quick to perform, and the manufacturer uses an extensive and easy-to-use material formula. The production materials are: the short-fiber, water-based adhesive, zinc oxide, antioxidant substance, photositiator, stearic, Potassium Stearate, potassium stearate, coupling agent and carbon fiber. Calculated based on the mass percentage. new non-slip materials includes 5-10 parts of the short cord, 0.5-5 portions of glue based on water, 3-7 parts zinc oxide 1-5 pieces of antioxidant 2-8 strips of stearic acids 1-5 components of photoinitiator, Potassium stearate 10-13 parts, 1-8 lengths of potassium 3-10 pieces of coupling agent plus 0.5-10 bits of carbon.
2. . used to prepare a graphene-modified glue
Graphene is added to existing glue to alter the resistance to high temperature of the 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 in the following order:
Level 1, the graphene gets added to n'butanol and toluene. The ultrasonic dispersion becomes uniform, to get 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. the temperature is reduced to 80 degrees C. ethylenediamine is added into the reactor, stirred thoroughly, and allowed to stand for a whole day to make the graphene-modified glue.
3. Preparation of composite anti-caking agent to be used in food-grade potassium chloride
To decrease the chance of having the risk of high blood pressure it's now permissible to add a fraction from potassium chloride to replace sodium chloride found in the salt. In the process transport and storage of potassium chloride contained in the product can cause dissolution and recrystallization of the powder's surface. This results in crystal bridges in its pores, and the crystals are combined to form a crystal bridge over time. to form. Huge mass. The weakening in fluidity can affect the use of table salt. So, to ensure that there is no agglomeration essential to use a suitable amount of anticaking agent during the production process.
The anticaking additive used in food grade potassium chloride is non-toxic, harmless colored, and odorless. It's composed of D-mannitol the potassium stearate compound, potassium, 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 as well as calcium dihydrogen diphosphate, is food grade. In comparison to the prior art the invention has advantages of being colorless or lightly white, does not alter the whiteness of potassium chloride. is free of any cyanide or other toxic elements, and is completely safe and non-harmful.
4 . The preparation of high-molecular ethylene the waterproof membrane is made of polypropylene
Polyethylene polypropylene is a brand new material that has recently been utilized. Polypropylene is composed of polypropylene non-woven fabric and polyethylene as the basic raw material. It is composed from anti-aging chemicals and compounded by high-tech, new technology, and cutting-edge technology. The polyester polypropylene water-proof roll material with an integrated layer boasts a significant friction coefficient, excellent stability, high mechanical strength small linear expansion coefficient, large temperature range of temperature adaptation, superb weather resistance, chemical resistance and flexibility. It is a great green protection for the environment in the 21st century. The procedure for the preparation of the high-molecular ethylene polypropylene waterproofing membrane is based on the following steps:
Step 1: Measure the raw materials according to the following percentages by weight (80-130 parts of polyethylene resin, 10-20 parts of talcum powder. Five to 10 parts of silica fume, 5-10 parts from glass beads. 8-16 parts of potassium Stearate. 8-18 pieces carboxylated latex; 10-20 parts of the anti-aging agent;
Step 2: Put silica fume, talcum powder, potassium stearate and carboxylated styrenebutadiene latex into high-speed mixer, raise the temperature until 70-80 degrees C, mix at a high speed for 8 to 18 minutes, and then raise the heat to 95-100 deg C. Following that, glass microbead and polyethylene resin are added to the mixture is stirred at a high velocity for 10-20 minutes to make a blend;
Step 3: Add the mixture into the feeding zone in order to extrude and create the sheet of polypropylene, and then the plastic sheet completely with the help of the three-roller machine. Transfer this guide roller over to the tractor, trim the edges, then enter an electric coiler to make the product.
In comparison to the prior art, the positive advantages of the invention include an effect of synergy between plastic resins, such as talc silicon fume, glass microbeads, potassium stearate, carboxylated styrene-butadiene anti-aging agent, latex and the subsequent steps to prepare, particularly when the high-speed mixing procedure is used using a specific order for the input of the raw materials can be vital. In conjunction with the sequence used in the present invention it is evident that the performance of the produced high-molecular Polyethylene polypropylene waterproofing membrane can be superior that of traditional waterproofing membranes that are high-performance.
