What is Potassium stearate
What is Potassium Stearate ?
Potassium-stearate is also referred by the name of "potassium octadecanoate". White crystalline powder. It is soluble in hot water and insoluble in chloroform, ether or carbon disulfide. The aqueous solution tends to be alkaline to phenolphthalein or litmus while the ethanol solution somewhat alkaline to the phenolphthalein. It is obtained by neutralizing the reactions of stearic and potassium hydroxide. It is commonly used in the production from surfactants and fibre softeners. It is also utilized in the fabrication of anti-slip materials, graphene -modified glues Anti-caking agents, waterproof coils.
1 . This is used to create a novel kind for non-slip materials
The latest non-slip material is designed to have great wear resistance and antislip capability, and the raw materials in the formula are easily available for purchase. In the process of making it, the procedure is easy and simple to use, as well as the manufacturer has a vast and user-friendly material formula. Production materials include: small fiber, short fibre, water-based glue Zinc Oxide, Anti-Aging substance, photoinitiator, stearic acids, Potassium thermo-sulfate, potassium, coupling agent and carbon fiber. Measured according to the percentage of mass, this non-slip new material comprises 5-10 parts of the short cord, 0.5-5 part of water-based glue. Three to seven pieces of zinc oxide 1-5 pieces of antioxidant, 2- 8 slices of Stearic acids 1-5 parts of photoinitiator Potassium stearate 10-13 parts, 1-8 components of potassium Stearate three to ten parts of coupling agents, plus 0.5-10 part of carbon.
2. . used to create a graphene-modified glue
Graphene can be added to the existing glue to modify the high-temperature resistance of cement as well as 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 in the following order:
Level 1, the graphene component is added to nbutanol and toluene, ultrasonic dispersion is uniform. 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;
Step 3, the above reaction is stopped. it is then lowered to around 80 degrees Celsius. ethylenediamine gets added to the reactor, stirred thoroughly, and allowed to stand for one day to obtain an unmodified graphene glue.
3. Preparation of anti-caking composites for use in potassium chloride that is food grade
To reduce the risk of higher blood pressure it is now allowed to add part from potassium chloride to replace sodium chloride from the edible salt. In the course that involves the storage and transportation of potassium chloride in the product promotes the recrystallization and dissolution of powder's surface. This creates a crystal bridge at the pores of the powder, and the crystals then combine together over time to form. Huge mass. The weakness of fluidity affects its usage in table salt. Therefore, in order to avoid agglomeration, it's required to add an appropriate quantity of anti-caking agents during the process of production.
The anticaking agent composite used in food-grade potassium chloride is non-toxic harmless as well as colorless and odorless. It is made up of D-mannitol, potassium stearate, and calcium dihydrogenphosphate. the particular gravity of D'mannitol potassium stearate, as well as dihydrogen phosphate is (1.25-5): (0.1-0.4): 1. The purity of D-mannitol, potassium stearate, and calcium dihydrogen and phosphate is food grade. In comparison to the prior art it has the advantages of being colorless or lightly white, it does not alter the hue of the potassium chloride and is free of any cyanide or other toxic elements, and is completely safe and harmless.
4 . The production of high-molecularly polyethylene polyester waterproof membrane
Polyethylene polypropylene is a new material that was recently used. Polypropylene is made up of non-woven polypropylene fabric and polyethylene as the primary raw material. It is made with anti-aging components and created by high-tech, modern technologyand innovation. The polymer polyethylene and polypropylene composite waterproof roll material with an integrated coating has a huge friction coefficients, excellent quality, durability and a small linear expansion coefficient, broad temperature range of adaptation, outstanding chemical resistance, weather resistance, and flexibility. The characteristic is an ideal green protection for the environment in the new century. The preparation method of the high-molecular Polyethylene polypropylene waterproofing membrane is based on the following steps:
Step 1: Weigh the raw materials in accordance with the following weight percentages for the following quantities: 80-130 portions of polyethylene resin, 10-20 portions of Talcum powder, 5-10 pieces of silica fume, 5-10 parts from glass beads. 8-16 parts of potassium stearate. 8-18 pieces, carboxylated, styrenebutadiene latex; 10-20 parts of anti-aging agents;
Step 2: Mix silica fume, talcum powder in combination with potassium stearate and carboxylated polystyrene-butadiene (latex) high-speed mixer. Turn up the temperature to 70-80 degrees C, stir at high speed for about 8 to 18 mins, and then raise the heat to 95 to 100 deg C. Following that, polyethylene resin and glass microbeads are added to the mixture is stirred up at a high speed for 10-20 minutes for a mix;
Step 3: Place the mixture into the feeding area to extrude the sheet of polypropylene as well as the plastic sheet in the complete manner using the three roller machine. Next, transfer this guide roller over to an tractor, cut off the edges and then insert the coiler for the finished product.
Comparing to conventional methods, positive effects of the invention are that it creates synergistic effects by in the form of polyethylene resin silica fume, glass microbeads, potassium stearate, carboxylated styrene-butadiene the latex, anti-aging substance, and subsequent preparation steps. especially When the high-speed mixing is carried out with the proper order of input of the raw materials is especially crucial. When combined with the sequence of the present invention and the effectiveness of the prepared high-molecular polyethylene polypropylene waterproofing membrane far exceeds that of the standard high-performance waterproofing membrane.
