Problems solved by technology

Practice has proved that although the various performance indicators of the "white primer" currently used can meet the needs of three-layer structure anticorrosion, when implementing three-layer structure coating, it is often due to dim light in rainy days and fatigue of night shift operators. The reason is that when the white primer transparent film breaks accidentally, it is ignored, so that the anti-corrosion pipe is waste due to the intermittent lack of adhesive

Abstract

The invention relates to a color adhesive and method used for three layer anticorrosive of the burying steel conduit. It is composed of the base resin 100, the antioxygen 0.1-0.5, the light stabilizer 0.1-0.5 and the organic dye 0.01-0.0005. The base resin is the PP or PE resin. The medium adhesive has the color in burying steel conduit and the mechanics performance has been improved, also the identification to the bottom flue film in coating is strengthened.

Description

technical field [0001] The invention relates to an adhesive and a preparation method thereof, in particular to a colored adhesive used for the three-layer anticorrosion intermediate layer of buried steel pipelines and a preparation method thereof. The color adhesive includes all "three PE" anticorrosion and "three PP" anticorrosion used in three-layer structure. Background technique [0002] Since the three-layer structure anti-corrosion came out in the last century, the middle layer adhesive has always been the original white color of PE or PP resin, so it is also called "white primer". Practice has proved that although the various performance indicators of the "white primer" currently used can meet the needs of three-layer structure anticorrosion, when implementing three-layer structure coating, it is often due to dim light in rainy days and fatigue of night shift operators. The reason is that when the white primer transparent film breaks unexpectedly, it is ignored, so t...
