What is Potassium stearate ?
Potassium Stearate can also be described for its alias "potassium octadecanoate". White crystalline powder. Soluble in hot water, insoluble in chloroform, ether as well as carbon disulfide. The aqueous solution is strongly alkaline in comparison to phenolphthalein or litmus and the ethanol mixture has a slight alkaline form to phenolphthalein. It is obtained by neutralizing the reaction of stearic acids with potassium hydroxide. It is frequently used in the making for surfactants as well as fiber softeners. It is also used to create anti-slip material, graphene modified glues anti-caking agents, as well as waterproof coils.
1. . utilized to prepare a completely new type or non-slip substance
The latest non-slip material is designed to have great wear resistance and antislip performance. The raw materials used in the formula is easy to acquire. When it comes to manufacturing, the method is simple and quick to perform, and the producer has a vast and user-friendly material formula. Production materials include: long fibers of short cord, water-based glue, zinc oxide, antioxidant substance, photoinitiator, stearic acids, Potassium thermo-acetate, potassium stearate or coupling agent, and carbon fiber. Calculated based on the mass percentage, this innovative non-slip material contains 5-10 parts of very short fibers 0.5-5 three parts water-based glue. of zinc oxide 1- 5 parts of antioxidant, 2-8 strips of stearic acid 1-5 pieces of photoinitiator, Potassium stearate 10-13 parts, 1-8 pieces of potassium stearate, 3-10 parts of coupling agent, in addition to 0.5-10 bits of carbon.
2. . Used to prepare graphene-modified glue
Graphene adds to the existing glue to modify the resistance to high temperatures 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 component is added to nbutanol and toluene, the ultrasonic dispersion is 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;
Step 3: The above reaction is stopped. the temperature is lowered to 80 degrees C. ethylenediamine is added to the reaction, thoroughly stirred and then left to stand for a day in order to produce a graphene-modified glue.
3. Preparation of composite anti-caking agent for use in food-grade potassium chloride
To decrease the possibility of elevated blood pressure it is now permissible to add a fraction of potassium chloride , which replaces sodium chloride in the food salt. In the course of transportation and storage of potassium chloride, the moisture contained in the product causes breakdown and recrystallization on the powder's surface. This creates an intergranular bridge in porous areas of powder as well as the crystals get incorporated in time to form. Huge mass. The weakness of fluidity affects its use in table salt. Thus, to ensure that there is no agglomeration required to add an appropriate amount of anticaking agent to the process of production.
The anti-caking agent that is a composite in food grade potassium chloride is safe, harmless as well as colorless and odorless. It's made up of D mannitol, potassium stearate, 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-mannitoland potassium stearate as well as calcium dihydrogen diphosphate, is food grade. When compared with prior art this invention has benefits of being colorless, or somewhat white, it does not alter the colour of potassium chloride. It also does not contain cyanide, is non-toxic, and safe.
4. . The preparation of high-molecular polyethylene waterproof membrane made from polypropylene
Polyethylene polypropylene is a brand new material that has recently been utilized. Polypropylene is composed of polypropylene non-woven fabric and polyethylene for the primary raw material. It is made from anti-aging chemicals and made by the latest high-tech technology, and new technology. The polyester polypropylene water-proof roll material that has an integrated layer offers a large friction coefficient, exceptional durability, stability, high mechanical strength as well as a very low linear expansion coefficients, a large temperature adaptability range, exceptional chemical resistance, weather resistance and elasticity. This is a desirable green product for environmental protection in the current century. The preparation method of the high-molecular Polyethylene polypropylene waterproofing membrane consists of the following steps:
Step 1: Measure the raw materials using the following weights by weight that is 80-130 parts of polyethylene resin. Also, 10-20 percent of talcum powder. 5-10 parts of silica fume. Five to ten parts of glass beads, and 8-16 parts of potassium stearate. 8-18 pieces of carboxylated latex, 10-20 pieces of anti-aging agents.
Step 2: Mix talcum powder, silica fume as well as potassium stearate and carboxylated styrene-butadiene in a high-speed mixer. Increase the temperature until 70-80 degrees C. Stir at a rapid speed for 8-18 min, and then increase the heat up to 95-100 deg Celsius. Following that, glass microbead and polyethylene resin are added, and the mixture is stirred at high rate for 10 to 20 minutes in order to obtain a combination;
Step 3: Insert the mixture into the feeding zone make extrusions and form the sheets of polypropylene and plastic sheet in the complete manner using the three roller machine. Next, transfer one of the guide rollers to the tractor, trim the edge, then go through in the coiler machine to produce the finished product.
In comparison with the prior art, the advantageous effects of the invention are the synergistic effect produced by the polyethylene resin, silica fume, glass microbeads potassium stearate anti-aging agent, latex and the subsequent steps to prepare, especially When the high-speed mixing process is being carried out by a sequence of introducing the raw materials is very important. In combination with the sequence used in the present invention its performance, the made high-molecular polyethylene polypropylene waterproofing membrane outperforms traditional waterproofing membranes that are high-performance.
