What is Potassium stearate ?
Potassium stearate may also be referred for its alias "potassium octadecanoate". White powder with crystalline structure. Soluble in hot water, insoluble in chloroform, ether and carbon disulfide. The aqueous solutions are strongly alkaline to phenolphthalein or litmus and the ethanol mixture has a slight alkaline form to phenolphthalein. It can be obtained by neutralizing the reaction of stearic acetic acid with potassium hydroxide. Commonly utilized in the fabrication of fiber softeners and surfactants. It can also be used in the production of anti-slip adhesives, graphene modified glues anti-caking agents, as well as waterproof coils.
1. . The 1 is used to design a different kind that is non-slip.
The non-slip new material comes with robust wear resistance and anti-slip performance. Additionally, the raw components in the formula are readily available for purchase. In the production process, the method is simple and user-friendly, and the manufacturer has an extensive and practical material formula. Materials used in production include long fibers of short cord, water-based glue, zinc oxide, anti-aging substance, photoinitiator and stearic acid. Potassium thermo-sulfate, potassium stearate coupled agent, carbon fiber. All of these are calculated according to the mass percentage, this new non-slip material Including 5-10 pieces of fiber, 0.5-5 elements of water-based adhesive, 3-7 pieces zinc oxide, 1-5 pieces antioxidant, two to eight slices of stearic acid 1-5 components of photoinitiator, Potassium Stearate 10-13 Parts, 1-8 parts in potassium stearate, 3- 10 parts coupling agent as well as 0.5-10 elements of carbon.
2. . Used to prepare graphene-modified glue
Graphene is added to 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 below:
Level 1: The graphene is mixed with n-butanol and toluene. Ultrasonic dispersion becomes 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 decreases to 80 degrees C. an ethylenediamine solution is added to reactor, mixed uniformly and then left to stand for a whole day to make graphene-modified adhesive.
3. Preparation , mixing and preparation of composite anticaking agent for use in potassium chloride food grade
To minimize the possibility of the risk of high blood pressure it is now permissible to add a fraction of potassium chloride to substitute sodium chloride from the edible salt. However, during the process in the storage and transport of potassium chloride contained in the product can cause melting and recrystallization powder's surface. This creates an elongated crystal structure in all the pores within the powder, and crystals are then bonded with each other over time to develop. Huge mass. The weakening effect of fluidity affects the use of table salt. Therefore, in order to stop agglomeration from occurring, it is necessary to add an appropriate quantity of anti-caking agents during the process of production.
The composite anti-caking agent used in food grade potassium chloride is safe, harmless, colorless, and odorless. It is composed of D-mannitol along with potassium stearate and calcium dihydrogen phosphate. the specific gravity of D'mannitol potassium stearate, as well as dihydrogenphosphate are (1.25-5): (0.1-0.4) 1. The purity of D-mannitol, potassium Stearate, and calcium dihydrogen phosphate are food grade. Comparatively to prior art this invention has the advantages of colorless or slightly white, does not change the whiteness of potassium chloride. is free of cyanide, is non-toxic, and is safe.
4. . The process of making high-molecular polyethylene waterproof membranes made of polypropylene
Polyethylene Polypropylene is a novel substance that has come into use in recent years. Polypropylene is composed of polypropylene non-woven fabrics and polyethylene as the main raw material. It is made of anti-aging agents and is created by high-tech, modern technology, and cutting-edge technology. The polyester polypropylene water-proof roll material with an integrated layer has significant friction coefficient, excellent quality, durability smaller linear expansion coefficients, a large temperature adaptability range, exceptional weather resistance, chemical resistance and elasticity. This is a desirable environmentally friendly product for the new century. The preparation method of the high-molecular Polyethylene polypropylene waterproofing membrane is as follows:
Step 1: Measure the raw materials in accordance to the following percentages by weight including 80-130 ppm of polyethylene resin, 10-20 portions of talcum powder. 5-10 parts of silica fume. 5-10 parts from glass beads. 8-16 parts of potassium Stearate. 8-18 pieces of carboxylated styrene butadiene latex, 10-20 parts of the anti-aging agent;
Step 2: Put silica fume, talcum powder potassium stearate, carboxylated butadiene-styrene latex into a high-speed mixer. Then, increase temperatures to 70-80 degrees C, then stir it at high speed for about 8 to 18 mins, and then raise the heat until it reaches 95-100 degrees C. Then, glass microbeads made of polyethylene are added to the mix is stirred vigorously at high speed for 10-20 minutes in order to get a mixture
Step 3: Add the mixture in the feeding area create the extrusion and Polypropylene sheet, as well as the plastic sheet in the complete manner using the three roller machine. Then, connect the guide roller onto an tractor, cut off the edges, then move into the coiler for the product.
When compared with existing art beneficial effects of the invention are the synergistic effect produced by polyethylene resin, talc silica-based fumes and glass microbeads, potassium stearate latex, anti-aging ingredient, as well as the subsequent preparation steps. particularly when the high-speed mixing is performed by a sequence of introducing the raw materials can be vital. In conjunction with the sequence of the invention and the effectiveness of the developed high-molecularly polyethylene polypropylene waterproofing membrane surpasses that of traditional waterproofing membranes that are high-performance.
