Abstract

The invention relates to a polymer emulsion, and particularly relates to an organic silicone emulsion and a production technology thereof. The organic silicone emulsion comprises the following components in parts by weight: 100 parts of organic silicone crude oil, 20-35 parts of epoxy-terminated organic silicone hyperbranched resin, 10-18 parts of graphene oxide dispersion liquid, 5-8 parts of anemulsifying agent, 5-8 parts of a co-emulsifier, 0.5-3 parts of glacial acetic acid, and 50-75 parts of distilled water. The organic silicone emulsion has the following beneficial effects: (1) the preparation processes are simple; (2) all components are uniformly and stably mixed; and (3) emulsion cannot be broken during being stored and transported.

Description

technical field [0001] The invention relates to a polymer emulsion, in particular to a silicone emulsion and a production process thereof. Background technique [0002] The official chemical name for silicone is polydiorganosiloxane. It has an "inorganic" scaffold composed of alternating silicon atoms and oxygen atoms, and the remaining two valences of silicon atoms are connected to organic terminal groups (mostly methyl groups), which allows silicone to partially possess the characteristics of organic substances. Because the bond energy of the Si-O bond is much higher than that of the CC bond, this plays a very important role in the ability of silicone to resist the influence of different factors and maintain stability. [0003] Silicone emulsion (referred to as silicone emulsion) is an oil-in-water emulsion composed of silicone oil, water and surfactants. This form of emulsion is easily further diluted with water, thus enabling even small amounts of substance to be evenl...
