Problems solved by technology

These methods are not only complicated in process and labor-intensive, but also the grease produced will cause high-temperature loss in hot areas and brittle cracks in cold areas, which will cause phenomena such as fracture, dead buckle, and corrosion of railway fasteners or damage to spiral casings (non-metallic). ) produces swelling effect and loses the fastening effect, so that it cannot be effectively protected for a long time, resulting in unsafe hidden dangers
Road stud grease imported from abroad is not only expensive, but also has poor temperature resistance and rain erosion resistance, and is easy to lose

Abstract

The protective oil and grease is prepared with the materials including lithium hydroxide hydrate, dodecahydroxyl stearic acid, stearic acid, composite antirust agent, composite antioxidant, filming agent, solid stuffing and base oil. It has excellent waterproof performance, antioxidation, anticorrosion, lubricant performance, adhesion performance, salt mist resistance and weather resistance and low cost, and may be smeared directly. The present invention may be used in long term protection of connecting parts and fastening parts in railway, outdoor crown block, crane, etc.

Description

technical field [0001] The invention relates to a protective grease, in particular to long-term protective grease for track fasteners (bolts, threaded spikes) such as railways, outdoor cranes, cranes, and subways, as well as equipment anchor bolts, fastening bolts, and connecting bolts. Background technique [0002] With the speed up of railway locomotives in our country, the protection requirements for railway fasteners (bolts, threaded spikes, etc.) are getting higher and higher. At present, calcium-based grease (butter), ordinary engine oil or asphalt is used for heating and brushing in China. These methods are not only complicated in process and labor-intensive, but also the grease produced will cause high-temperature loss in hot areas and brittle cracks in cold areas, which will cause phenomena such as fracture, dead buckle, and corrosion of railway fasteners or damage to spiral sleeves (non-metallic). ) produces swelling and loses the fastening effect, so that it cann...
