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.

Description

technical field [0001] The invention belongs to the field of material technology, in particular to an organosilicon polymer composite emulsion and a preparation method thereof. Background technique [0002] At present, with the advancement of social science, a new type of organosilicon polymer composite material has been born in forestry materials. This organosilicon polymer composite material utilizes high-speed mechanical shearing and impact, or combined with chemical pretreatment The composite material is separated into microfibers with a diameter below 100 nm. Compared with silicone polymer composite materials, this silicone polymer composite material has excellent mechanical properties, its elastic modulus is close to 150GPa, and its tensile strength exceeds 2GPa. At the same time, the surface of these organosilicon polymer composite materials is rich in hydroxyl groups and has a large aspect ratio, and can be uniformly dispersed in aqueous solution at room temperature...
