What is Potassium Stearate ?
Potassium Stearate is also referred to by the name of "potassium octadecanoate". White powder with crystalline structure. It is soluble in hot water and insoluble in chloroform, ether or carbon disulfide. The aqueous solution appears to be alkaline and is phenolphthalein to litmus while the ethanol solution is slightly alkaline to phenolphthalein. It is produced by neutralizing the reaction between stearic acid and potassium hydroxide. It is often used in manufacturing in the production of surfactants, fiber softeners and so on. It is also utilized in the manufacture of anti-slip adhesives, graphene modified glues as well as anti-caking agents and waterproof coils.
1 . Used to make a new type that is non-slip.
The latest non-slip material is designed to have outstanding wear resistance as well as anti-slip performance, and the raw substances in the formula are natural to purchase. In the manufacturing process, the process is easy and user-friendly and the manufacturer has a vast and user-friendly material formula. Materials used in production include Short fiber, water-based glue, zinc oxideas well as anti-aging substance, photoinitiator, stearic acid Potassium thermo-sulfate, potassium coupled agent, carbon fiber, calculated according to the mass percentage. innovative non-slip material contains 5-10 pieces of very short fibers 0.5-5 elements of water-based adhesive, 3-7 pieces of zinc oxide 1-5 antioxidant pieces 2-8 slices , stearic acids 1-5 parts of photoinitiator, Potassium Stearate 10-13 Parts, 1-8 parts in potassium stearate three to ten parts of coupling agents, in addition to 0.5-10 parts of carbon fiber.
2 . It is used to make a graphene-modified glue
Graphene can be added to the existing glue to alter its high-temperature resistance 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 steps specific to HTML0 are as the following:
Level 1, the graphene component is added to nbutanol and toluene, the ultrasonic dispersion becomes uniform, to produce 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 ceases, and the temperature is reduced to 80 deg C, ethylenediamine is added to the reactor, stirring it evenly and left to stand for a few days to create graphene-modified adhesive.
3. The preparation of composite anticaking agent to be used in food-grade potassium chloride
In order to lessen the chance of having excessive blood pressure it is currently permitted to add a little of potassium chloride as a replacement for sodium chloride in the edible salt. In the process in the storage and transport of potassium chloride, the moisture contained in the product encourages recrystallization and dissolution of the porous surface of the powder, resulting in crystal bridges within its pores and crystals are then bonded in time to form. Huge mass. The weakening effect of fluidity affects its use in table salt. In order to keep agglomeration at bay, it is crucial to add the correct quantity of anti-caking agents during the process of production.
The anti-caking agent that is a composite in food-grade potassium chloride is non-toxic harmless that is colorless, odorless, and colorless. It's composed of D-mannitol, potassium stearate, and calcium dihydrogen phosphate. the specific gravity of D'mannitol, potassium stearate, and dihydrogen phosphate is (1.25-5): (0.1-0.4) 1. The purity of the D-mannitol, potassium stearate and calcium dihydrogen phosphate is food grade. Comparatively to prior art this invention has the advantages of being completely colorless or white, is not able to alter the colour of potassium chloride. It also does not contain cyanide, is non-toxic, and non-harmful.
4 . The process of preparing high-molecular Polyethylene the waterproof membrane is made of polypropylene
Polyethylene polypropylene is a new material used in recent years. Polypropylene is composed of non-woven polypropylene fabric and polyethylene as the basic raw material. It is composed with anti-aging components and compounded by high-tech, new technologyand modern technology. The polymer polyethylene polypropylene composite waterproof roll material that has an integrated coating has a huge friction coefficient, superb stability, high mechanical strength as well as a very low linear expansion coefficient, broad temperature range for temperature adaptation, superior chemical resistance, weather resistance, and flexibility. The characteristic is an ideal green product for environmental protection in the current century. The method for making the waterproofing membrane comprises the following steps:
Step 1: Measure the raw materials in accordance with the following parts of weight including 80-130 ppm of polyethylene resin, 10-20 portions of the talcum powder, 5-10 portions of silica-based fume, 5-10 bits made of glass, as well as 8-16 pieces of potassium stearate. 8-18 pieces, carboxylated, styrenebutadiene latex, 10-20 pieces of anti-aging agents;
Step 2: Place talcum powder, silica fume, potassium stearate and carboxylated styrene butadiene latex in a high-speed mixer. Set the temperature to 70-80 degrees C, and stir at a high speed for between 8 and 18 minutes, and then raise the heat until it reaches 95-100 degrees C. Following that, glass microbeads made of polyethylene are added, and the mixture is stirred up at a high speed for about 10 to 20 minutes to make a blend;
Step 3: Put the mixture into the feeding area Extrude and then form the Polypropylene sheet, as well as the plastic sheet completely by the three-roller machine. Next, transfer one of the guide rollers to the tractor, cut the edges, then move into the coiler to get the final product.
Compared with the existing art positive effects of the invention are Synergistic effect from plastic resins, such as talc, silicon fume, glass microbeads potassium stearate and carboxylated styrene butad latex, anti-aging agent, as well as the subsequent preparation steps. especially When the high-speed mixing takes place at a particular order, the method of introducing ingredients is particularly vital. In conjunction with the sequence of the invention it is evident that the performance of the made high-molecular polyethylene polypropylene waterproofing membrane exceeds the typical high-performance waterproofing membrane.
