Manufacturing method of silicone acrylic lotion. In order to meet the requirements of different fields for the performance of silicone acrylic lotion, a manufacturing method is proposed in this paper to improve the stability and performance of silicone acrylic lotion

2、 Materials and Equipment 

1 Materials: acrylic monomer, siloxane monomer, initiator, emulsifier, water, etc

2. Equipment: mixing kettle, emulsifier, thermometer, pH meter, etc

3、 Manufacturing method 

1 Pre emulsification: add acrylic monomer, siloxane monomer, emulsifier and part of water into the pre emulsification kettle, and stir evenly to form a pre lotion

2. Polymerization reaction: pump the pre lotion into the polymerization kettle, add initiator, raise the temperature to the set temperature, and carry out polymerization reaction. During the reaction process, the smooth progress of the reaction is ensured by controlling the temperature and pH value

3. Post treatment: after the reaction, cool to room temperature, add the remaining water, adjust the pH value to neutral, filter to remove impurities, and obtain the finished silicone acrylic lotion

4、 Notes 

1 Strictly control the ratio of monomers and initiators to ensure complete polymerization reaction

During the polymerization reaction process, it is necessary to closely monitor changes in temperature and pH value, and adjust process parameters in a timely manner

3. During post-treatment, the stability of lotion shall be ensured to avoid demulsification

5、 Performance testing 

1 Stability: Put the silicone acrylic lotion in the thermostat, and observe whether there are layering, demulsification and other phenomena

2. Solid content: Determine the solid content in silicone acrylic lotion by drying method

3. Viscosity: measure the viscosity of silicone acrylic lotion with a viscometer

4. pH value: use a pH meter to measure the pH of silicone acrylic lotion

6、 Results and Discussion 

Through the above manufacturing method, we successfully prepared silicone acrylic lotion with good stability and excellent performance. The experimental results show that the lotion has good water resistance, weather resistance, chemical resistance and mechanical properties, which can meet the needs of different fields for raw materials for chemical production

In the discussion part, we can compare the performance of silicone acrylic lotion under different preparation conditions, and analyze the influence of various factors on the performance of lotion. For example, the effects of monomer ratio, initiator type and amount, reaction temperature and time on the stability, solid content, viscosity and pH of lotion can be discussed. In addition, we can also evaluate the performance of silicone acrylic lotion in different application fields, providing reference for actual production

7、 Conclusion 

This paper proposes a manufacturing method of silicone acrylic lotion. Through experimental verification, the silicone acrylic lotion prepared by this method has the characteristics of good stability and excellent performance, which can meet the needs of different fields for raw materials for chemical production. Meanwhile, this article also provides a detailed introduction to the precautions and performance testing methods that need to be taken during the preparation process, providing guidance for actual production.
