Abstract
The invention provides a kind of aqueous automobile chassis corrosion resistant coating, this automobile coating, by LH-302 resin 48-52, carbon black 2.0-2.5, iron black 7-9, modification aluminium triphosphate 12-13, organic nitrogen zinc salt 1-3, modified filler 9-11, wetting dispersing agent 0.3-0.5, corrosion inhibiter 0.8-1.0, ground wetting agent 0.3-0.5, auxiliary agent 0.1-2.0, deionized water 10-12, is mixed with and forms. Aqueous automobile of the present invention chassis corrosion resistant coating normal temperature can be from dry, low temperature drying (80～90 DEG C are dried 0.5 hour), and paint film property obviously strengthens, and adhesive force, hardness, salt fog resistance are all very desirable. Be mainly used in automotive axle, automobile chassis and auto parts and components etc.
Description
Technical field:
The present invention relates to paint field, be specifically related to a kind of aqueous automobile chassis corrosion resistant coating and preparation method thereof.
Background technology:
Along with people's environmental consciousness strengthens and the corresponding appearance of various countries' environmental regulation day by day, solvent reducible coatings is because its volatile organic compounds (VOC) content is high, severe contamination ecological environment, therefore its application is more and more restricted. Aqueous black automobile chassis corrosion resistant coating is a new technology of field of Environment Protection projection, it has adopted IPN ipn technology, not only reach zero VOC discharge, improve environment, reduce labour intensity, and film performance can want to match in excellence or beauty with solvent reducible coatings, construction equipment and execution conditions are also close with solvent reducible coatings construction, and diluent is ordinary tap water.
Summary of the invention:
The invention provides a kind of aqueous automobile chassis corrosion resistant coating preparation method. Product normal temperature of the present invention can be from dry, low temperature drying (80～90 DEG C are dried 0.5 hour), and paint film property obviously strengthens, and adhesive force, hardness, salt fog resistance are all very desirable. Be mainly used in automotive axle, automobile chassis and auto parts and components etc.
The technical solution used in the present invention is as follows for achieving the above object:
A kind of aqueous automobile chassis corrosion resistant coating, is characterized in that, its component by following weight portion is made:
LH-302 resin 48-52, carbon black 2.0-2.5, iron black 7-9, modification aluminium triphosphate 12-13, organic nitrogen zinc salt 1-3, modified filler 9-11, wetting dispersing agent 0.3-0.5, corrosion inhibiter 0.8-1.0, ground wetting agent 0.3-0.5, auxiliary agent 0.1-2.0, deionized water 10-12
The preparation method of described LH-302 resin is:
(1) take by weight following component:
