What is Potassium Stearate ?
Potassium Stearate is also referred to in the form of "potassium octadecanoate". White powder with crystalline structure. It is soluble in hot water and insoluble in chloroform, ether as well as carbon disulfide. The aqueous solution is alkaline with phenolphthalein and litmus and the ethanol mixture will be slightly alkaline to that of phenolphthalein. It can be obtained by neutralizing the reactions of stearic and potassium hydroxide. Commonly used in the manufacture in the production of surfactants, fiber softeners and so on. It can also be utilized in the fabrication of anti-slip glues, graphene-modified gluing also known as anti-caking substances, as well as waterproof coils.
1 . used to develop a new kind of non-slip material
The latest non-slip fabric has high wear resistance and anti-slip performance, and the raw materials that make up the formula are readily available for purchase. In the process of making it, the method is simple and user-friendly, and the manufacturer provides an extensive and practical material formula. The production materials are: long fibers of short cord, water-based glue zinc oxide, antioxidant agent, photositiator, stearic, Potassium thermo-sulfate, potassium stearate, coupling agent and carbon fiber. Based on its mass percentage. innovative non-slip material contains 5-10 parts of length cord 0.5-5 parts of water-based glue, 3-7 pieces zinc oxide, 1-5 parts of antioxidant 2-8 slices , stearic acid 1-5 parts of photoinitiator Potassium Stearate 10-13 Parts, 1-8 lengths of potassium 3-10 parts of coupling agent as well as 0.5-10 elements of carbon.
2. . used to create a graphene-modified glue
Graphene is incorporated into the existing glue to modify the resistance to high temperature of the cement as well as 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 in the following order:
Level 1, the graphene will be added to the n'butanol and toluene, ultrasonic dispersion is uniform, to get 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: Above reaction ceases, and it is then lowered to around 80 degrees Celsius. in the step 3, ethylenediamine enters the reactor, which is stirred continuously for a few minutes, then allowed to sit for a day in order to produce the graphene-modified glue.
3. Preparation of a composite anti-caking agent to be used in potassium chloride food grade
To decrease the possibility of the risk of high blood pressure it is currently permitted to add a little of potassium chloride to replace sodium chloride in the edible salt. However, during the process that involves the storage and transportation of potassium chloride, the moisture contained in the product facilitates the recrystallization and dissolution of powder's surface. This results in a crystal bridge at porous areas of powder, and the crystals then combine with each other as they continue to form. Huge mass. The weakening in fluidity can affect the use of table salt. In order to prevent agglomeration, it is essential to use a suitable amount of anti-caking agent in the production process.
The anti-caking agent that is a composite in food-grade potassium chloride is non-toxic, harmless, colorless, and odorless. It's comprised of D'mannitol along with potassium stearate and calcium dihydrogen phosphate. the particular 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 dihydrogenphosphate is food grade. In comparison to the prior art the invention has advantages of being colorless or slightly white, and does not alter the colour of potassium chloride. It also does not contain cyanide, is not toxic, and safe.
4 . The production of high-molecular-polyethylene waterproof membrane made from polypropylene
Polyethylene Polypropylene is an innovative material which has been in use for a while. Polypropylene is made up of polypropylene fabric that is non-woven and polyethylene as the main raw material. It is made of anti-aging compounds and manufactured using high-tech, advanced technologyand innovation. The Polymer Polyethylene Polypropylene Composite waterproof roll material with an integrated layer is characterized by a high friction coefficients, high stability, high mechanical strength, small linear expansion coefficient, wide temperature adaptation range, excellent chemical resistance, weather resistance and elasticity. This makes it a perfect environmentally friendly product for the 21st century. The method for making the high-molecular polyethylene polypropylene waterproofing membrane is as follows:
Step 1: Weigh the raw materials using the following parts of weight in the range of 80-130 parts polyethylene resin, 10-20 pieces of the talcum powder, 5-10 portions of silica fume, 5-10 parts that are glass beads. Also, 8-16 parts of potassium Stearate. 8-18 pieces of carboxylated latex, 10-20 parts of anti-aging agents;
Step 2: Put talcum powder, silica fume along with potassium stearate as well as carboxylated styrenebutadiene latex into high-speed mixer. Set temperatures to 70-80 degrees C. Mix at a fast speed for 8 to 18 min, and then increase the temperature by 95-100 degrees Celsius. Following that, glass microbeads and polyethylene resin are added and the mixture is stirred on high speed for about 10-20 minutes until you get a perfect mixture.
Step 3: Place the mixture into the feeding area to extrude the polypropylene sheet and the plastic sheet completely using the three-roller machine. After that, you can pass this guide roller over to your tractor, then cut the edgeand then go into the coiler to create the finished product.
In comparison to the previous art positive effects of this invention include: synergistic effect by an adsorbent polyethylene resin, silica fumes, glass microbeads potassium stearate, carboxylated butadiene in the form of anti-aging and latex and subsequent preparation steps, especially when high-speed mixing occurs, the order of inputting ingredients is particularly crucial. In combination with the sequence of the invention The performance of the created high-molecular polyethylene and polypropylene waterproofing membrane can be superior that of the conventional high-performance waterproofing membrane.
