What's Potassium stearate ?
Potassium stearate may also be referred for its alias "potassium octadecanoate". White powder with crystalline structure. It is soluble in hot water and insoluble in ether, chloroform as well as carbon disulfide. The aqueous solution is alkaline, ranging from litmus to phenolphthalein The ethanol solution will be slightly alkaline to that of phenolphthalein. It can be made by neutralizing the reaction of stearic acetic acid with potassium hydroxide. It is commonly used in the production for surfactants as well as fiber softeners. It can also be used in the creation of anti-slip glues, graphene-modified gluing in addition to anti-caking and waterproof coils.
1. . used to prepare a new kind that is non-slip.
The new non-slip material has outstanding wear resistance as well as anti-slip performance. The raw ingredients in the formula are organic and easy to obtain. For the production process, the method is simple and user-friendly and the producer has the largest and most convenient formula. Materials used in production include brief fiber, water-based glu, zinc oxide, antioxidant agents, photositiator, stearic, Potassium stearate, potassium or coupling agent, and carbon fiber. Based on the mass percent, this new non-slip material includes 5-10 parts of shorter cords, 0.5-5 components of water-based glue. 3-7 bits of zinc oxide 1-5 parts of antioxidant 2-8 slices , stearic acids, 1-5 parts of photoinitiator Potassium Stearate 10-13 parts 1-8 lengths of potassium 3-10 components of coupling, along with 0.5-10 parts of carbon fiber.
2 . This is used to prepare a graphene modified glue
Graphene can be added to the existing glue to alter the high-temperature resistant of the cement and improve 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 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, and the temperature is reduced to around 80 degrees Celsius. and ethylenediamine added to the reactor, and stirred evenly for a few minutes, then allowed to sit for one day to obtain the graphene modified glue.
3. Preparation of a composite anti-caking agent for use in potassium chloride that is food grade
To decrease the chance of having increased blood pressure it's now allowed to add part of potassium chloride to replace sodium chloride that is present in the salt. However, in the process that involves the storage and transportation of potassium chloride contained within the product stimulates melting and recrystallization powder surface, thereby forming one of the crystal bridges that are formed in these pores, and the crystals combine to form a crystal bridge over time. to develop. Huge mass. The weakening in fluidity can affect its use in table salt. Therefore, in order to stop agglomeration from occurring, it is important to add a sufficient amount of anti-caking agent during the process of production.
The composite anti-caking agent used in food-grade potassium chloride is safe, harmless, colorless, and odorless. It is comprised of D-mannitol the potassium stearate compound, potassium, and calcium dihydrogenphosphate. the particular gravity of D'mannitol potassium stearate and dihydrogen phosphate are (1.25-5): (0.1-0.4) 1. The purity of the D-mannitols, potassium stearates, as well as calcium dihydrogen diphosphate, is food grade. In comparison to the prior art the invention has benefits of being colorless, or somewhat white, is not able to alter the color of potassium chloride, is free of cyanideand is therefore non-toxic and safe.
4. . The process of preparing high-molecular Polyethylene waterproof membrane of polypropylene
Polyethylene polypropylene is a new material that has recently been utilized. Polypropylene is composed of polypropylene fabric that is non-woven and polyethylene as the primary raw material. It is composed of anti-aging substances and compounded by high-tech, new technologyand innovative technology. The polyester polypropylene water-proof roll material that has an integrated layer features a significant friction coefficients, excellent quality, durability, small linear expansion coefficient, wide temperature adaptability, great chemical resistance, weather resistance, and flexibility. This makes it an ideal green protection for the environment in the new century. The procedure for the preparation of the waterproofing high-molecular polyethylene polypropylene membrane consists of the following steps:
Step 1: Measure the raw materials in accordance to the following percentages by weight for the following quantities: 80-130 portions of polyethylene resin; 10-20 parts of Talcum powder, 5-10 pieces of silica gas, 5-10 portions from glass beads. 8-16 pieces of potassium Stearate. 8-18 pieces of carboxylated styrene butadiene latex, 10-20 percent from the anti-aging agent.
Step 2: Place silica fume, talcum powder the potassium stearate, silica fume and carboxylated styrene butadiene latex in a high-speed mixer. Increase temperatures to 70-80 degrees C. Stir the mixture at high rate for between 8 and 18 min, and then increase the temperature until it reaches 95-100 degrees C. Then, glass microbead and polyethylene resin are added and the mixture is stirred with a high rate for 10 to 20 minutes in order to make a blend;
Step 3: Add the mix into the feeding space Extrude and then form the sheet of polypropylene, and then the plastic sheet in the complete manner using the three roller machine, pass one of the guide rollers to the tractor, cut the edge, and enter in the coiler machine to produce the product.
Comparing to earlier art advantageous results of the invention comprise an effect of synergy between polyethylene resin, talc silica fumes, potassium stearate, carboxylated styrene-butadiene latex, anti-aging agent, and subsequent preparation processes, especially when high-speed mixing occurs using a specific order for the input of the raw materials is especially important. Together with the sequence of the invention the performance of the prepared high-molecular polyethylene polypropylene waterproofing membrane is superior to the standard high-performance waterproofing membrane.
