Modification Of Solid Paraffin/Acrylate Latex

In this paper, The general situation of paraffin, the research and development of emulsion polymerization, involving solid paraffin modified acrylate latex, were reviewed. The solid paraffin-acrylate latex with content of 45% solid was prepared. The modification of solid paraffin-acrylate latex system was most stable.The best emulsifications of solid paraffin latex were the emulsification temperature was 85 degree, reaction time was 70 minute, stirring speed was 1500 rpm, use the boiling water as solution of emulsifier. polymerization. With solid paraffin was modified acrylate made to modification of solid paraffin-acrylate latex. With the stability of the emulsion as assessment indices, the optimum process conditions for preparing solid paraffin-acrylic acid modified emulsion were determine .The solid paraffin latex made at the best condition and the acrylic ester were synthesized to get modification latex. With synthesizing solid paraffin-acrylate modification latex, the orthogonal experiment method was applied to select the best result. These results listed as follows, the content of initiator was 0.2% of total emulsion amount; OP-10 as emulsifier and its content was 6% of total amount; the solid paraffin latex was 20g; the function acrylate was acrylic and occupied 6% of total amount.The optimized preparation craft of modification latex were The first, with solid paraffin latex and acrylate were emulsion, and dropping initiator; reaction time 270 minute, the stirring speed was 1200 rpm, The final test results showed that most of properties of modification of solid paraffin-acrylate latex such as stability, waterproof ability and the smooth of film etc. were superior to pure acrylate latex, compared with modification of liquid paraffin-acylate latex, modification of solid paraffin-acylate was cheaper.
