[0002] As an important raw material for a variety of industrial products such as explosives, adhesives, and coatings, the preparation process of latex matrix requires strict control of the mixing ratio, temperature, and stirring effect of the raw materials. Traditional methods of preparing latex matrix mostly use static mixing or batch mixing, which have problems such as uneven mixing, high energy consumption, and low production efficiency.
