Simple Technology

The epoxy acrylate emulsion was made by hybrid emulsion polymerization. This method has simple technology, none solvent and friend to the environment. The epoxy acrylate hybrid emulsion was prepared by using core-shell emulsion polymerization technology. The factors, such as epoxy resin, emulsifier ,initiator and functional monomer, were investigated by the orthogonal experiment. The relation of interactional factors was confirmed, and one kind of steady emulsion was made. The best formulation condition of modified emulsion could be obtained when N-MA was 1%, MAA was 2%, emulsifier was 3%, epoxy resin was 6%, initiator was 0.6%. The structure of modified styrene acrylic hybrid emulsion was characterized by FT-IR, the peaks at 915cm-1 and 1251cm-1 correspond respectively to the motion of epoxy group and phenylate, so the graft polymer was confirmed.

Core Shell Structure

Core-Shell structure Poly(vinyl acetate-butyl acrylate) emulsion is prepared by the semi-continuous emulsion polymerization. And the emulsion particles are modified by ethyleneglycol dimethacrylate crosslinker (EGDMA) to improve the properties of films in the different reaction stages. Then the emulsion particles structure is characterized by transmission electron microscopy (TEM) and Fourier transform infrared spectroscopy (FT-IR). The particle size and distribution are characterized by Zata Potential- Particle analyzer, as well as analysis of the film mechanical properties and thermal performance. The results show that the emulsion particles possess a clear core-shell structure. The performance of the emulsion film show better when 1% and 0.5% EGDMA are added in the second reaction and the third reaction stage respectively under the emulsion preparation process.

Abstract In this paper, acrylate-terminated polysiloxane was synthesised and used as raw materials for the synthesis of cationic core/shell polysiloxane acrylate emulsion, which was applied as binders in the pigment dyeing of cotton fabrics. The experimental results showed that: the cationic core/shell poly siloxane acrylate emulsion in this article is in nano size of 100nm. During the film formation of the emulsion, there are core-core and shell-shell fusion phenomena between the latex particles, and same poly siloxane chain aggregates on the surface of the film. When the emulsion is used in the pigment dyeing of cotton fabrics, the dyed cotton fabrics feel soft, and the soaping fastness and dry/wet rubbing fastness meet the national quality requirements, as soaping fastness can reach grade 4 ~ 5, dry rubbing fastness can reach grade 4 ~ 5, and wet rubbing fastness can reach grade 4.
