High-temperature grease for middle/high-density board dried chain

Abstract

The invention discloses high-temperature grease for a middle / high-density board dried chain. The high-temperature grease utilizes polyalphaolefin as base oil and a plurality of composite additives as accessory materials. The composite additives comprise a densifier, an antirust agent, an anti-oxidant and a dispersant assistant. The high-temperature grease for the middle / high-density board dried chain has excellent oxidation stability and rust resistance and can be used in a long-term high-temperature work environment. The high-temperature grease has outstanding viscosity temperature performances, has good performances of protecting the chain and a bearing, avoids wearing and corrosion on friction pairs, has stable composition, no obvious change of denseness at a high temperature and no phenomenon of grease loss, can satisfy equipment lubrication and protection requirements on the middle / high-density board dried chain at a high temperature and can prolong service lives of equipment and components.

Description

technical field [0001] The invention belongs to the field of high-temperature lubricating grease for drying chains of medium and high density boards. Background technique [0002] Wood-based panel is a whole board composed of units of various shapes through adhesives, which is one of the composite materials. Medium and high density boards are a type of wood-based panels. The wood-based panel production process is divided into two types: unit manufacturing and panel forming and processing. Different adhesives and functional additives are used in the production of wood-based panels. Therefore, in order to improve production efficiency and product quality, two production processes, drying and hot pressing, are usually used. [0003] The medium and high density board drying chain is exposed to high temperature environment for a long time, it is easy to produce thermal deformation, and the strength will also be reduced. In addition, it will cause the lubricant used in the equ...

Problems solved by technology

[0003] The medium and high density board drying chain is exposed to high temperature environment for a long time, it is easy to produce thermal deformation, and the strength will also be reduced

In addition, it will also cause the lubricant used in the equipment to volatilize, dry up and deposit carbon, causing the equipment to run in a non-lubricated state, reducing the service life of the equipment, and even causing lubrication accidents
