What is Potassium stearate ?
Potassium stearate is also known for its alias "potassium octadecanoate". White powder with crystalline structure. Soluble in hot water, insoluble in chloroform, ether and carbon disulfide. The solution in aqueous form is alkaline in comparison to phenolphthalein or litmus The ethanol solution will be slightly alkaline to that of phenolphthalein. It is obtained by neutralizing the reaction of stearic acetic acid with potassium hydroxide. It is often used in manufacturing detergents, surfactants and softeners. It is also used in the creation of anti-slip adhesives, graphene modified glues also known as anti-caking substances, as well as waterproof coils.
1 . used to develop a new kind of non-slip material
The new non-slip surface has solid wear resistance, as well as anti-slip ability, and the ingredients in the formula are easily available for purchase. The manufacturing process is the procedure is easy and easy to operate, and the manufacturer uses an extensive and easy-to-use material formula. Production materials include: long fibers of short cord, water-based glue, zinc oxide(zinc oxide), anti-aging substance, photoinitiator, stearic acids, Potassium stearate, potassium stearate coupled agent, carbon fiber. These are calculated in accordance with the percentage of mass, this non-slip new material comprises: 5-10 parts of short cord, 0.5-5 three parts water-based glue. zinc oxide, 1-5 antioxidant pieces 2-8 strips of stearic acids 1-5 pieces of photoinitiator Potassium stearate 10-13 parts, 1-8 pieces of potassium stearate 3-10 elements of coupling, also 0.5-10 elements of carbon.
2. . Used to prepare graphene-modified glue
Graphene is added to the existing glue to alter the resistance to high temperature of the 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 added to n-butanol and toluene. The ultrasonic dispersion becomes uniform, to 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;
In step 3, the reaction is stopped, and the temperature drops to 80 deg C, and ethylenediamine added to the reactor, which is stirred continuously, and allowed to stand for one day to obtain graphene-modified adhesive.
3. Preparation and formulation of composite anti-caking agents for use in potassium chloride food grade
To reduce the possibility of elevated blood pressure it's now permitted to add a portion of potassium chloride that replaces sodium chloride in the food salt. However, in the process in the storage and transport of potassium chloride, the moisture contained in the product encourages breakdown and recrystallization on the powder's surface. This results in a crystal bridge at the pores of the powder and then the crystals join with each other over time to develop. Huge mass. The weakness of fluidity affects its use in table salt. Thus, to prevent agglomeration, it is crucial to add the correct amount of anticaking agent in the production process.
The composite anti-caking agent used in food grade potassium chloride is non-toxic, harmless and colorless. It also has no odor. It is composed of D-mannitol in combination with potassium stearate as well as calcium dihydrogen phosphate. the particular gravity of D'mannitol potassium stearate and dihydrogenphosphate are (1.25-5): (0.1-0.4) 1. The purity of the D-mannitolcompound, potassium stearate and calcium dihydrogen and phosphate is food grade. In comparison to the prior art this invention has the advantages of being colorless or lightly white, doesn't alter the whiteness of potassium chloride. does not contain cyanide, is safe, and safe.
4. . The preparation of high-molecular ethylene waterproof membrane made from polypropylene
Polyethylene polypropylene has become a revolutionary material that has recently been utilized. Polypropylene is a blend of polypropylene fabric that is non-woven and polyethylene as the basic raw material. It is composed of anti-aging agents and is blended with high-tech technological advancements and new technologies. The polyester polypropylene water-proof roll material that has an integrated layer features a significant friction coefficients, high durability, stability, high mechanical strength small linear expansion coefficient, broad temperatures, good chemical resistance, weather resistance, and flexibility. This is a desirable eco-friendly product to protect the environment in the new century. The process of making the high-molecular ethylene polypropylene waterproofing membrane involves the following steps:
Step 1: Weigh the raw materials according to the following weights by weight the following: 80-130 pieces of polyethylene resin, 10-20 portions of talcum powder. 5-10 parts of silica fume. Five to ten parts made of glass, as well as 8-16 parts of potassium stearate. 8-18 pieces of carboxylated styrene-butadiene latex, 10-20 pieces of the anti-aging substance;
Step 2: Mix talcum powder, silica fume along with potassium stearate as well as carboxylated styrene-butadiene in a high-speed mixer. Turn up the temperature to 70 to 80 deg C, then stir it at high rate for between 8 and 18 min, and then increase the heat to 95 to 100 degrees Celsius. Then, glass microbead and polyethylene resin are added, and the mixture is stirred on high rate for 10 to 20 minutes in order to make a blend;
Step 3: Add the mix into the feeding space Extrude, then form the sheet of polypropylene, and then the plastic sheet fully using the three-roller machine. Then, connect the guide roller on the tractor, then cut the edge, then go through an electric coiler to make the finished product.
Compared with the previously known techniques, the beneficial results of the invention are Synergistic effect from plastic resins, such as talc, silica fumes, potassium stearate, carboxylated butadiene latex, anti-aging agents, and subsequent preparation processes, especially when high-speed mixing takes place according to the order of the inputting of the raw materials is particularly crucial. In conjunction with the sequence of the present invention and the effectiveness of the made high-molecular polyethylene polypropylene waterproofing membrane outperforms that of the traditional high-performance waterproofing membrane.
