Abstract

The invention provides double-component fast-curing plastic cement which is composed of a component A and a component B. The component A comprises polyether polyol, a curing agent, surface hydroxyl modified paraffin, a thickening agent and solid filler. The component B comprises polyether polyol, a catalyst, a cross-linking agent, surface hydroxyl modified paraffin, a thickening agent and a solidfiller. Paraffin with a certain hydroxyl on the surface is introduced into the two components so that certain surface lubricity is provided, and hands of an operator cannot be stuck during kneading; meanwhile, hydroxyl on the surface can react with isocyanate so that the compatibility is good after curing and the material is prevented from cracking, powdering and deforming due to migration. In addition, due to good compatibility, the cement obtained after curing has very good weather resistance in high-temperature, high-humidity, high-salt and other environments, and can play a role in protecting and plugging electrical equipment for a long time in a severe environment.

Description

technical field

[0001] The invention belongs to the field of polymer functional materials, and in particular relates to a two-component fast-curing plastic clay and a preparation method thereof. Background technique

[0002] In order to prevent electrical equipment, wires, etc. from leaking, they are generally sealed and protected with anti-leakage tape. However, this method cannot isolate electrical equipment from contact with water vapor, and cannot achieve a complete sealing effect. Long-term use has a greater potential safety hazard of short circuit. At the same time, after some equipment, including connectors, wires are oxidized, the resistance increases and the heat generation increases significantly, which affects the service life of cables and wires, and is easy to burn out the wires and cause accidents.

[0003] In the prior art, some cement is often used to block and protect electrical equipment and wire joints. Traditionally, red mud is used for dehydration cur...
