Abstract
The modified barium sulfate is prepared through the technological steps of: crushing barium sulfate to 300-350 mesh size; adding polyvinyl alcohol and zinc ricinate in the amount of 3-5% weight of barium sulfate each; and mixing at 75-95 deg.c and under stirring of 300-700 rpm for 0.4-0.6 hr. Compared with the un-modified product, the present invention has greatly raised acid and alakali corrosion resistance, obviously improved grinding dispersivity and relevant performance, obviously improved brightness and weather resistance of lacquer film, and obviously raised lacquer quality and stability.
Description
Technical field
The present invention relates to material, specifically be meant barium sulfate as paint component.
Background technology
Barium sulfate is used by people as paint component.The barium sulfate of prior art is littler than great, powder surface and coating (paint) avidity, easily layering in coating, and form lumphy structure gradually, influence the stability of quality product.
Summary of the invention
The objective of the invention is, develop modified barium sulphate, it can improve painting quality and stability after adding as paint component greatly.
Technical scheme of the present invention is that described modification sulfuric acid steel barium adopts following starting material and technology to obtain:
(1) blaue fixe is broken to 300-350 order granularity;
(2) add polyvinyl alcohol, zinc ricinate; The add-on of the two is the 3-5% of barium sulfate weight;
(3) under 75-95 ℃ of temperature condition, be that 300-700rpm mixed discharging 0.4～0.6 hour with the stirring velocity.
Below make and further specifying.
The present invention is through further investigation and just achieving success of trial-production repeatedly.
Know-why of the present invention is to adopt corresponding macromolecular compound that powder surface is carried out modification; Through check, it is qualified that the product activation index is greater than 85%.
As known from the above, the present invention is a kind of modified barium sulphate, this moderate product price that makes thus, acid-and base-resisting and corrosion resistance nature improve greatly, can significantly improve grind dispersity and dispersed other relevant performance in the system lacquer process, the original gloss of paint film and weather resisteant also obviously improve, and have improved the quality product and the stability of paint greatly.
Embodiment
A kind of modified barium sulphate is crushed to 325 orders, adds weight ratio and is 4% polyvinyl alcohol, zinc ricinate, mixes 0.5 hour with the 500rPm rotating speed under 80 ℃ of temperature, promptly.Equipment used is the CH-500DY high-speed mixer (production of Beijing plastics machinery factory) with pulverizing and mixing functions, feed bin cubic capacity 500L, speed of mainshaft 335-670rpm, power of motor 47-67KW.
Claims (1)
