A kind of anti-adhesive wheel solid modified grease for road roller and preparation method thereof

Abstract

The invention provides anti-sticking wheel solid-state modified grease for a road roller. The anti-sticking wheel solid-state modified grease is prepared from grease, organic silicone waxes and sulphur. A preparation method of the anti-sticking wheel solid-state modified grease comprises the steps of heating the grease and the organic silicone waxes together, and stirring while heating, thus fully dissolving the organic silicone waxes; then adding the powdery sulphur, stirring while heating, thus enabling a mixture to be uniform, then cooling, continuously stirring during the initial stage of cooling, stopping stirring when the mixture reaches a sticky state and the sulphur is not separated, then pouring into a cuboid container, and cooling to normal temperature. When the anti-sticking wheel solid-state modified grease is used, an iron ring is made, the inner space of the iron ring is enabled to be cuboid, the iron ring is fixed on the road roller, is located on the top of a rolling wheel and presses the rolling wheel of the road roller by means of the gravity of the solid-state modified grease, and when the rolling wheel of the road roller rotates to generate relative movement, the solid-state modified grease is smeared on the rolling wheel of the road roller, thus solving the problems that a liquid anti-cohesion agent is inconvenient to use, uneven and unsafe, and causes cooling of a hot mixed asphalt mixture.

Description

technical field [0001] The invention relates to the technical field of asphalt pavement construction, in particular to a solid-state modified grease for an anti-adhesion wheel for a road roller and a preparation method thereof. Background technique [0002] After the hot mix asphalt mixture is paved, it needs to be rolled and compacted with a road roller to become a road surface. JTG F40-2004 "Technical Specifications for Construction of Highway Asphalt Pavement" stipulates that when the grade of asphalt used is 70 # At the same time, the initial pressure temperature of the hot mix asphalt mixture should not be lower than 130°C, and the final pressure temperature should not be lower than 70°C. For polymer asphalt mixture, the construction temperature should be increased by 10°C to 20°C. However, if rolling directly with a roller, the hot mix asphalt mixture will be stuck to the rolling wheel, so JTG F40-2004 "Technical Specifications for Construction of Highway Asphalt Pavem...
