Description
Technical Field

Background
The high solid content styrene-butadiene latex refers to styrene-butadiene latex with the solid content of more than 60 percent, and is mainly applied to the fields of preparing latex sponge mattresses, carpet sponge backings and the like. The preparation of the high solid content styrene-butadiene latex is divided into a one-step method and a two-step method (synthesis and concentration), and although the preparation methods are different, the key is to synthesize latex particles with large particle size and wide particle size distribution.
The one-step method is a method for synthesizing high-solid-content latex in one step with low water ratio and high conversion rate without concentration, and generally adopts a semi-continuous method, wherein the actual conversion rate is about 95 percent, and the solid content is 60 to 63 percent. The method has the advantages that the latex with high solid content is directly synthesized in one step, the latex does not need to be subjected to post-concentration treatment, the difficulties are that the high viscosity under high conversion rate needs to be overcome in the later reaction period, the requirement on stirring is high, the reaction time is long, the efficiency is low, and more gel is easily generated in the later reaction period.
The two-step method for synthesizing the high-solid-content styrene-butadiene latex comprises the following two steps: firstly, latex with large particle size and wide particle size distribution is prepared and then concentrated to high solid content. The method has high production efficiency and becomes the first choice in the industry. The physical agglomeration method destroys the stability of latex particles by changing temperature, pressure, and external force application, etc., so that small particles are aggregated into large particles. However, the method has the disadvantages of wide particle size distribution, high power consumption, and limited size of particle size increase. The chemical agglomeration method is to add acid or electrolyte into rubber latex with small particle size to reduce the stability of latex particles and to form large particles by rapid aggregation among particles. The general chemical agglomeration method also has the problems of limited particle size increase, and the defects of more generated aggregates, difficult control, difficult repetition and the like.
