Elastic lotion is an important raw material for chemical production, which is widely used in coatings, adhesives, textiles and other fields. This article will introduce the manufacturing method of elastic lotion, including the steps of raw material preparation, lotion preparation, post-treatment, etc., and elaborate the operating points, equipment requirements and precautions of each step

1、 Raw material preparation 

The main raw materials of elastic lotion include elastic polymer, emulsifier, solvent, etc. When selecting raw materials, factors such as product quality, production costs, and environmental requirements should be considered. Specifically, elastic polymers with good elasticity, weather resistance, and water resistance should be selected, as well as emulsifiers with appropriate HLB values, high emulsification efficiency, and low toxicity. In addition, solvents with low volatility and good solubility should also be selected

2、 Lotion preparation 

1 Pre emulsification: Add elastic polymers, emulsifiers, and some solvents to the pre emulsification kettle and stir at high speed to ensure thorough and uniform mixing. The purpose of pre emulsification is to disperse the elastic polymer into small particles and improve its dispersibility in lotion

2. lotion polymerization 

Add the pre emulsion into the lotion polymerization kettle, and add the remaining solvent and initiator to carry out lotion polymerization. During the polymerization process, factors such as reaction temperature, time, and pH value should be controlled to ensure the quality and stability of the product. At the same time, the solid content, particle size distribution and other indicators of lotion should be sampled and tested regularly to adjust the process parameters in time

3. Post treatment 

After the completion of lotion polymerization, carry out post treatment, including cooling, filtration, pH adjustment and other steps. The purpose of cooling is to prevent the thermal decomposition or deterioration of components in the lotion, the purpose of filtration is to remove impurities and gel in the lotion, and the purpose of pH adjustment is to make the lotion have a stable pH value

3、 Notes 

1 During the operation process, safety operating procedures should be strictly followed to avoid accidents

During the preparation process, attention should be paid to controlling various process parameters to ensure the quality and stability of the product

3. In the process of use, appropriate elastic lotion should be selected according to the requirements of specific fields, and used correctly according to the specified proportion and use method

In a word, the manufacturing method of elastic lotion includes the steps of raw material preparation, lotion preparation and post-treatment, among which the operation points and equipment requirements of each step are different. In order to ensure the quality and stability of the product, it is necessary to strictly control various process parameters and comply with safety operating procedures. At the same time, it is necessary to use it correctly according to the specific requirements of the field during use.
