Abstract
The invention discloses a novel daub for graphite bonding, and belongs to the field of graphite equipment bonding materials. The daub comprises the following components, by mass, 60-80% of water glass, 10-20% of a curing agent, and 10-20% of graphite powder. According to the daub for graphite bonding in the present invention, volatile components are less, and the water glass has low viscosity so as to gradually eliminate produced volatile component bubbles, such that no bubble exists inside the daub after curing, and the cured section is smooth; and the daub can resist a temperature of 400 DEG C while a heat temperature requires only 130 DEG C.
Description
Technical field
The present invention relates to graphite equipment with the bonding filler, be specifically related to a kind of novel graphite bonding and use clay.
Background technology
Traditional clay generally is made up of resin (resol, furane resin etc.), Graphite Powder 99, solidifying agent, and heat resistance is general maximum 180 ℃ (concrete heat resistance is by thermal treatment process, and heat treatment process temperature high temperature tolerance more is good more).Send out composition (for example moisture, free phenol, free aldehyde etc.) owing to contain multiple meeting in the resin, these volatile matters can send gradually in curing and heat treatment process, cause clay inside bubble to occur, influence bonding strength.There is bubble in this type clay section after fixed line.
Summary of the invention
Goal of the invention: the present invention provides the novel graphite bonding that a kind of temperature tolerance is good, thermal treatment temp is low, can there be bubble in cured glue mud inside to use clay in order to solve the deficiency of prior art.
The technical scheme that the present invention adopts: a kind of novel graphite bonding uses clay, said clay to comprise the water glass of following component by mass percent: 60-80%, the solidifying agent of 10-20%, the Graphite Powder 99 of 10-20%.
As optimization, the mass percentage content of silicon-dioxide is 30-60% in the said water glass.
As optimization, containing mass percent in the said solidifying agent is the 4-8% Sodium Silicofluoride 98min.
As optimization, said graphite powder particle degree is the 100-130 order.
Beneficial effect: novel graphite bonding of the present invention is less with the clay volatile component, and because water glass viscosity is very little, and the volatile matter bubble of generation can be got rid of gradually, does not therefore have bubble in cured glue mud inside, and the section after the curing is smooth.The type clay heat resistance can reach 400 ℃, and thermal treatment temp only needs 130 ℃ and gets final product.
