Abstract

The invention discloses an organosilicon additive for inhabiting coating pigment reunion and settlement and relates to the technical field of organosilicone materials. The organosilicone additive is prepared from, by weight, 10-15 parts of emulsified silicone oil, 6-11 parts of polyvinyl butyral, 4-8 parts of modified chlorinated paraffin, 3-6 parts of C5 petroleum resin, 2-4 parts of active magnesium oxide, 2-4 parts of tricetyl phosphate, 1-2 parts of microcrystalline wax, 1-2 parts of sulfated castor oil, 1-2 parts of vulcanized lard oil, 1-2 parts of 2-methyl cyclopentanone, 1-2 parts of dimethyl phosphate, 0.5-1 part of zinc dihydrogen phosphate, 0.5-1 part of edetic acid, 0.5-1 part of cyclopropylmagnesium bromide and 0.5-1 part of sodium tripolyphosphate. The organosilicone additive is short in preparation period and low in cost, uniform dispersion of pigments is facilitated by synergistic effect of raw materials through strictly controlled temperature rising and dropping speed and feeding sequence, and reunion and settlement of the pigments are prevented.

Description

[0001] Technical field: [0002] The invention relates to the technical field of organosilicon materials, in particular to an organosilicon additive that inhibits the agglomeration and sedimentation of paint pigments. [0003] Background technique: [0004] Pigment is the coloring substance of paint, which is used to give paint color and enhance its aesthetics. However, it was discovered in the paint processing process that agglomeration may sometimes occur after adding pigments to the paint. Even if stirring is strengthened, it is difficult to mix the pigments evenly. In addition, during the storage and storage of the paint, evenly dispersed pigment particles may settle to the Paint the bottom, thus affecting the normal use and coloring effect of the paint. In response to this situation, the company has developed a silicone additive that inhibits the agglomeration and sedimentation of paint pigments to promote the uniform dispersion of pigments, thereby ensuring the coloring effect...
