What's Potassium stearate ?
Potassium stearate can also be referred to by the name of "potassium octadecanoate". White crystalline powder. Soluble in hot water, insoluble in ether, chloroform or carbon disulfide. The aqueous solution tends to be alkaline and is phenolphthalein to litmus, and the ethanol solution is slightly alkaline to phenolphthalein. It is made by neutralizing the reaction of stearic acid with potassium hydroxide. Commonly utilized in the fabrication of softeners for fibers and other surfactants. It is also used to create anti-slip glues, graphene-modified gluing as well as anti-caking agents and waterproof coils.
1. . used to develop a new type of slip-resistant material
The new non-slip materials has high wear resistance and anti-slip performance, and the raw substances in the formula are easy to acquire. For the production process, the procedure is easy and easy to follow, and the producer has an extensive and easy-to-use material formula. Materials used in production include long fibers of short cord, water-based glue zinc oxide, anti-aging agent, photoinitiator, stearic acids, Potassium stearate, potassium stearate as well as coupling agent and carbon fiber, calculated according to the mass percentage. novel non-slip product includes 5-10 parts of the fiber, 0.5-5 components of water-based glue. 3-7 bits zinc oxide one to five 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 3-10 pieces of coupling agent plus 0.5-10 part of carbon.
2 . used to prepare graphene-modified glue
Graphene adds to the existing glue to modify the high-temperature resistance of 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 steps specific to HTML0 are as follows:
Level 1, the graphene is added to n-butanol and toluene. Ultrasonic dispersion remains 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 the temperature drops to 80 degrees C. an ethylenediamine solution is added to reactor, stirred uniformly for a few minutes, then allowed to sit for a day to yield one graphene-modified gluing.
3. Preparation of a composite anticaking agent for use in potassium chloride that is food grade
To lessen the possibility of excessive blood pressure it's now permissible to add a fraction from potassium chloride to replace sodium chloride in the edible salt. In the course in the storage and transport of potassium chloride, the moisture in the product facilitates the dissolution and recrystallization of powder surface, thereby forming an intergranular bridge in all the pores within the powder and the crystals are merged to form a crystal bridge over time. to form. Huge mass. The weakening in fluidity can affect the use of table salt. So, to stop agglomeration from occurring, it is necessary to add an appropriate amount of anticaking agent throughout the process of production.
The composite anti-caking agent used in food grade potassium chloride is non-toxic, harmless colored, and odorless. It's made of D-mannitol the potassium stearate compound, potassium, and calcium dihydrogenphosphate. 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 are food grade. When compared with prior art, the invention has the advantages of being completely colorless or white, does not change the brightness of potassium chloride. does not contain cyanide, is safe, and harmless.
4 . The production of high-molecular polyethylene polypropylene waterproof membrane
Polyethylene Polypropylene is an innovative substance that has come into use in recent years. Polypropylene is composed of non-woven polypropylene fabric and polyethylene is the principal raw material. It is made with anti-aging components and processed using the most advanced, high-tech technologies and advanced technology. The polymer polyethylene and polypropylene composite waterproof roll material with an integrated layer features a significant friction coefficient, great stability, high mechanical strength and a small linear expansion coefficients, a large temperature range of temperature adaptation, superb weather resistance, chemical resistance, and flexibility. The characteristic is an ideal eco-friendly product to protect the environment in the current century. The process of making the waterproofing membrane includes the following steps:
Step 1: Weigh the raw materials in accordance to the following weight percentages that is 80-130 parts of polyethylene resin, 10-20 pieces of Talcum powder; 5-10 parts of silica fume, 5-10 pieces of glass beads, and 8-16 parts of potassium Stearate. 8-18 pieces of carboxylated styrene butadiene latex, 10-20 pieces of the anti-aging agent
Step 2: Add silica fume, talcum powder silica fume, potassium stearate, and carboxylated latex of styrene and butadiene into high-speed mixer. Turn up the temperature to 70-80 deg C, stir at high speed for 8 to 18 min, and then raise the heat by 95-100 degrees Celsius. After that, a polyethylene resin and glass microbeads are added and the mix is stirred vigorously at high velocity for 10-20 minutes for a mix;
Step 3: Pour the mixture into the feeding zone, extrude and form the polypropylene sheet as well as the poly sheet entirely using the three-roller machine. Once the machine is in place, it will pass the guide roller to the tractor, trim the edge, then go through the coiler to create the finished product.
In comparison to the earlier art positive results of the invention are an effect of synergy between the polyethylene resin silica-based fumes and glass microbeads, potassium stearate, carboxylated butadiene anti-aging agent, latex and any subsequent preparation steps, particularly when the high-speed mixing procedure is used, the order of inputting the raw materials can be important. When combined with the sequence used in the present invention The performance of the made high-molecular polyethylene polypropylene waterproofing membrane will be better than the high-performance membranes for waterproofing.
