Title:
PREPARATION METHOD FOR STYRENE-BUTADIENE LATEX WITH CONTROLLED PARTICLE SIZE
Document Type and Number:
WIPO Patent Application WO/2018/095349
Kind Code:
A1
Abstract:
The invention discloses a preparation method of styrene-butadiene latex with controlled particle size. The preparation method of the styrene-butadiene latex with controlled particle size comprises the following steps: inputting two kinds of seed latexes with different particle sizes, and adding butadiene and styrene monomers in two batches so as to carry out seeded semi-continuous emulsion polymerization to obtain styrene-butadiene latex of which the particle size is controllable and the particle size distribution is wide. A styrene-butadiene latex with high solid content (60% or higher) and good mobility can be obtained by performing subsequent concentration or agglomeration on the styrene-butadiene latex with controlled particle size. The styrene-butadiene latex with controlled particle size has the advantages of rapid film forming speed, as well as low energy consumption in dry storage and transport, and so on; thus, the application range and fields of the styrene-butadiene latex can be further expanded.
