Problems solved by technology

[0003] The technical problem to be solved by the present invention is to propose a nano-modified special anti-corrosion paint for many defects such as high content of toxic substances, non-environmental protection, high energy consumption, unstable quality, and poor anti-rust performance in the existing anti-corrosion and anti-rust paint. Rust primer, effectively reduces the content of harmful substances, can greatly reduce the degree of environmental pollution of products, but also improves the quality of products, anti-rust effect is good, so that the quality level of anti-corrosion and anti-rust paint has risen to a new height

Abstract

A nanometre-sized modified special rust-inhibiting primer is characterized in that it includes the following components (mass %): 29.0-60.0 % anti-corrosive paint host, 1.0-10.0 % nano oxide addition,5.0-15.0 % curing agent and 30.0-65 % diluent. The said anti-corrosive paint consists of rust-preventive material, coloring pigment, compounded resin and auxiliary agent, the curing agent is compounded by 75 % aromatic isocyanate, dimethylbenzene, butyl acetate, propanol and 2-butanol and the diluent is combination of alcohol and ester solvent. The invention has conducted adequate optimization and association for the components of the rust-inhibiting primer and its proportioning, which has largely reduced the contents of the toxic substance and the harmful substance in the total weight of the products, not only can guarantee the champion cryogenic film-forming property, but also can reduce the degree of pollution to the environment, which can effectively support the health of the maker, the user and the surrounding people, fitting requirement of the environmental protection, simultaneously can further improved the quality of the rust-inhibiting primer.

Description

technical field [0001] The invention relates to the technical field of metal coatings, in particular to a special metal anti-rust primer, which is mainly used for corrosion and anti-rust coating on the surface of mechanical equipment and metal structural parts, especially suitable for mechanical equipment, injection molding machines, die-casting machines, Protective and decorative coating for spark machines, CNC machining centers, air compressors, elevators, motors and other equipment and manufacturing industries. Background technique [0002] At present, most of the existing anti-corrosion and anti-rust paints are solvent-based paints, and their solvents are generally based on benzene organic solvents such as xylene, which are used as diluents for pigments, paints, etc., and their content is relatively high. Xylene is a colorless and transparent liquid, insoluble in water, soluble in ethanol and ether, toxic, volatile, can pollute air and environment, and seriously endanger...
