What is Potassium stearate
What is Potassium Stearate ?
Potassium stearate may also be referred in the form of "potassium octadecanoate". White powder with crystalline structure. Soluble in hot water, insoluble in ether, chloroform and carbon disulfide. The aqueous solutions are strongly alkaline to litmus and phenolphthalein The ethanol solution has a slight alkaline form to phenolphthalein. It can be obtained by neutralizing the reaction of stearic acid with potassium hydroxide. It is widely used in the production of fiber softeners and surfactants. It can also be employed in the manufacturing of anti-slip adhesives, graphene modified glues in addition to anti-caking and waterproof coils.
1 . used to prepare a new type of slip-resistant material
The new non-slip surface has outstanding wear resistance as well as anti-slip performance. Furthermore, the raw substances in the formula are naturally available to purchase. In the manufacturing process, the process is easy and easy to operate, and the producer has an extensive and efficient formula. The production materials are: brief fiber, water-based glu, zinc oxide, anti-aging agent, photoinitiator, stearic acid Potassium Stearate, potassium stearate in combination with coupling agent and carbon fiber. Measured according to the mass percentage, this new non-slip material Including: 5-10 parts of fiber, 0.5-5 parts of water-based glue, 3-7 pieces of zinc oxide, 1- 5 parts of antioxidant, two to eight slices of stearic acids 1-5 parts of photoinitiator Potassium stearate 10-13 parts, 1-8 parts in potassium stearate 3-10 parts of coupling agent plus 0.5-10 elements of carbon.
2 . used to prepare graphene-modified glue
Graphene is added to the existing glue to modify the high-temperature resistant 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 follows:
Level 1, the graphene component is added to nbutanol 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;
Step 3, the above reaction is stopped. the temperature drops to 80 deg C, ethylenediamine gets added to the reactor, stirred thoroughly, and allowed to stand for a few days to create one graphene-modified gluing.
3. Preparation of a composite anticaking agent to be used in potassium chloride food grade
To lessen the chance of having elevated blood pressure it's now permitted to add a portion of potassium chloride to replace sodium chloride from the edible salt. However, in the process transport and storage of potassium chloride, the moisture contained in the product causes breakdown and recrystallization on the powder's surface, which results in the formation of crystal bridges at each of the powder's pores, and crystals are then bonded with each other as they continue to form. Huge mass. The weakening of fluidity influences the use of table salt. So, to avoid agglomeration, it's imperative to add the right amount of anti-caking agent during the process of production.
The anticaking agent composite used in food grade potassium chloride is non-toxic, harmless and colorless. It also has no odor. It's 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 the D-mannitol, potassium stearate, as well as calcium dihydrogen diphosphate, is food grade. When compared with prior art this invention has benefits of being colorless and slightly white, and does not alter the brightness of potassium chloride. does not contain cyanide, and is non-toxic and safe.
4 . The production of high-molecularly polyethylene waterproof membrane of polypropylene
Polyethylene Polypropylene, a new material that has recently been utilized. Polypropylene is composed of non-woven polypropylene fabric and polyethylene, which is the raw material. It is composed from anti-aging chemicals and added by high-tech technologyand innovative technology. The Polypropylene polyethylene composite waterproof roll material with an integrated layer is characterized by a high friction coefficient, exceptional quality, durability, small linear expansion coefficient, wide temperature adaptation range, excellent weather resistance, chemical resistance and elasticity. This is a fantastic sustainable product for protecting the environment in the current century. The procedure of making the high-molecular-molecular-molecular-polyethylene waterproof membrane is based on the following steps:
Step 1: Weigh the raw materials in accordance with the following weight percentages in the range of 80-130 parts polyethylene resin; 10-20 parts of Talcum powder, 5-10 pieces of silica gas, 5-10 portions that are glass beads. Also, 8-16 pieces of potassium stearate. 8-18 pieces of carboxylated latex and 10-20 parts of the anti-aging agent
Step 2: Put talcum powder, silica fume as well as potassium stearate and carboxylated styrenebutadiene latex into high-speed mixer. Turn up the temperature from 70 to 80 degrees C, and stir at a high speed for between 8 and 18 minutes, and then increase the heat by 95-100 degrees Celsius. After that, a glass microbeads and polyethylene resin are added to the mix is stirred vigorously at high speed for about 10 to 20 minutes until you get a perfect mixture.
Step 3: Pour the mix into the feeding space create the extrusion and sheet of polypropylene as well as the plastic sheet in the complete manner using the three roller machine. Once the machine is in place, it will pass one of the guide rollers to the tractor, then cut the edge, then go through the coiler to get the final product.
Comparing to conventional methods, advantageous effects of this invention include the synergistic effects of an adsorbent polyethylene resin silica fumes, potassium stearate and carboxylated styrene butad anti-aging agent, latex as well as the subsequent preparation steps. especially When the high-speed mixing occurs and the sequence of entering the raw materials is particularly crucial. When combined with the sequence of the present invention the performance of the constructed high-molecular-molecular-molecular-polypropy membrane exceeds that of the standard high-performance waterproofing membrane.
