Abstract
The invention discloses a kind of production method of ferro-phosphorus rust-preventive pigment, by (1) ferrophosphorus, (2) titanium dioxide, three kinds of components of (3) barium sulfate or lime carbonate are formed, earlier ferrophosphorus being changed fine powder with the broken machine of crocodile is broken to less than 8mm, the oven dry or dry to moisture content less than 1%, get ferrophosphorus, titanium dioxide, barium sulfate or lime carbonate mix, be broken to 〉=325 orders screenings≤1%, packing then with raymond grinding powder.The present invention has following beneficial effect, has avoided ferrophosphorus in the process catching fire even the blast that are used for producing ferro-phosphorus rust-preventive pigment, makes production safer; Ferrophosphorus is more cheap than other rust-stabilising pigment such as zinc powder price, has therefore reduced the production cost of rust-stabilising pigment.
Description
Technical field
The present invention relates to a kind of method for preparing pigment that is used to produce rust-inhibiting paint.
Background technology
Ferrophosphorus can be used for doing rust-stabilising pigment, but in the process that is used for producing ferro-phosphorus rust-preventive pigment, owing to contain higher phosphorus, catching fire, even blast easily, influence safety in production.
Summary of the invention
The ferro-phosphorus rust-preventive pigment production method that the purpose of this invention is to provide a kind of production process safety.
The objective of the invention is to realize in the following way: a kind of production method of ferro-phosphorus rust-preventive pigment, by (1) ferrophosphorus, (2) titanium dioxide, three kinds of components of (3) barium sulfate or lime carbonate are formed, earlier ferrophosphorus being changed fine powder with the broken machine of crocodile is broken to less than 8mm, the oven dry or dry to moisture content less than 1%, get ferrophosphorus, titanium dioxide, barium sulfate or lime carbonate mix, be broken to 〉=325 orders screenings≤1%, packing then with raymond grinding powder.
The present invention has following beneficial effect, has avoided ferrophosphorus in the process catching fire even the blast that are used for producing ferro-phosphorus rust-preventive pigment, makes production safer; The 2nd, ferrophosphorus is more easy than other rust-stabilising pigment such as zinc powder price, has therefore reduced the production cost of rust-stabilising pigment.
