Summary of the invention:

The problem that the present invention mainly solves provides a kind of preparation method of exterior wall nano-latex; This exterior wall latex paint is the special preparation of high standard building protection exterior wall; This product has good self-cleaning; Use in the time of nano titanium oxide and nano silicon; Make product have particular optical performance; Strengthened filming to ultraviolet receptivity, had advantages such as paint film is smooth, weather resistance strong, drying is rapid, adhere firmly, scrubbing resistance, strong covering power, good weatherability, color stable simultaneously, and nonpoisonous and tasteless; And compound method is simple, and the raw material of producing this product use has: water 28%, nano-dispersed agent 1%, skimmer 1%, coventional type Namigai 15%-17%, nano titanium oxide 2%, nano silicon 2%, C-40 film coalescence aid 1.5%, Ucar 35 2%, pure-acrylic emulsion 43%-45%, thickening material 1%, mould inhibitor 0.5%, pigment 1%.

The present invention can realize through following technical scheme:

A kind of method of batch preparations exterior wall nano-latex is characterized in that being made up of following steps:

1. water is sent into vertical grinding machine, agitator is adjusted to 2000 rev/mins with rotating speed, and the temperature remains within the normal range, adds nano-dispersed agent, skimmer successively, after stirring, adds coventional type Namigai, nano titanium oxide, nano silicon restir 60 minutes.

2. rotating speed is adjusted to 1100 rev/mins, adds C-40 film coalescence aid, Ucar 35, pure-acrylic emulsion successively, stirred 40 minutes, reach even no particle.

3. with speed drop to 400 rev/min, add thickening material, mould inhibitor, pigment successively, stir and promptly obtained finished product in 20 minutes.

The beneficial effect of product of the present invention is: the preparation method that a kind of exterior wall nano-latex is provided; This rubber-emulsion paint has good self-cleaning, particular optical performance, stronger ultraviolet absorption ability; Have advantages such as paint film is smooth, weather resistance strong, drying is rapid, adhere firmly, scrubbing resistance, strong covering power, good weatherability, color stable simultaneously, and compound method is simple.
