Problems solved by technology

However, nanofibrous films are completely bound by hydrogen bonds, and are easily damaged by water absorption in high-humidity environments, reducing performance, seriously restricting and affecting their service life and wide application.
[0003] Not only that, the thickness of these films is usually less than 0.2 mm, which will inevitably fail to give full play to the excellent mechanical properties of silicone polymer composites, and also limit the development and utilization of large-scale and large-diameter materials.

Abstract

The invention discloses an organic silicon polymer composite emulsion and a preparation method thereof. The organic silicon polymer composite emulsion is prepared from the following components in parts by weight: 5-500 parts of ethylene vinyl acetate, 90-110 parts of organic silicon and 1-5 parts of a catalyst, wherein the organic silicon is one or more of phenethyl methyl polysiloxane, phenethylmethyl hydrogen-containing polysiloxane, substituted phenethyl methyl polysiloxane or substituted phenethyl methyl hydrogen-containing polysiloxane. The organic silicon polymer composite emulsion disclosed by the invention is a white viscous emulsion, and the organic silicon and the ethylene vinyl acetate form a cross-linked structure or an interpenetrating network structure, so that the originalphenomena of scattering, sand lost and spalling of pervious concrete can be effectively improved, and properties such as compressive strength of the pervious concrete can be increased.
