Abstract

The invention relates to the field of the preparation of chemical coatings, in particular to an environment-friendly primer and top-coat integrated coating special for a coal machine and a preparation process for the coating. The primer and top-coat integrated coating comprises the following components in percentage by weight: 12 to 20 percent of chlorinated rubber, 3 to 7 percent of phenolic resin, 0.5 to 2 percent of dispersing agent, 5 to 9 percent of composite ferrotitanium powder, 15 to 25 percent of rutile titanium white, 8 to 16 percents of talcpowder, 1 to 3 percent of anti-settling agent, 3.5 to 7 percent of plasticizer and 21 to 36 percent of solvent. In the primer and top-coat integrated coating, the chlorinated rubber is used as a main film-forming substance, and the environment-friendly composite ferrotitanium powder is used as an antirust pigment; the product has high corrosion resistance, antirust performance, water resistance, weather resistance and hardness, is dried quickly, and can be constructed at the temperature of between -30 and 40 DEG C; the primer and top-coat integrated coating has an effect of primer and top-coat integration, and the thickness of a filmformed at one time is 100 micrometers; the product accords with restriction of hazardous substances (ROHS) instructions; and a preparation process is simple and is suitable for industrial production.

Description

Technical field [0001] The invention relates to the field of chemical coating preparation, in particular to an environment-friendly coal machine special bottom surface all-in-one coating and a preparation process thereof. Background technique [0002] Coal is an important energy product, and the development of the coal industry has brought a profound impact on modern society. Throughout the history of the development of the world coal industry, it can be seen that coal occupies an advantageous position in the primary energy output and consumption structure. In 2010, the national output of raw coal was 3.24 billion tons, an increase of 8.9% over 2009. [0003] The rapid development of the coal industry has driven the increase in demand for coal machinery. Most of the anticorrosion of existing coal machinery is matched with primer and topcoat. The primer is usually red lead or chromate anticorrosive paint, which contains high heavy metals and volatile organic compounds, and has low...
