Self-emulsifying organic silicon powder water repellent and preparation method thereof

The invention relates to a self-emulsifying organic silicon powder water repellent which is good in waterproof effect, good in dispersity and capable of improving the strength of mineral mortar and apreparation method of the self-emulsifying organic silicon powder water repellent. The self-emulsifying organic silicon powder water repellent is prepared from self-emulsifying polysiloxane, MQ silicon resin, an anti-caking agent and inorganic filler. According to the invention, excessive introduction of a hydrophilic emulsifier is avoided through a self-emulsifying agent technology, so that the waterproof performance is further improved, meanwhile, the self-emulsifying silicone oil has better dispersity than mechanically emulsified silane, can more effectively disperse and combine a mineral mortar base material, and has the advantages of low water absorption and good waterproof effect compared with the existing waterproof agent; meanwhile, the effect of improving the compressive strengthis achieved; the binding p
