Title:
COMPOSITION FOR REFRACTORY BRICK, REFRACTORY BRICK, AND METHOD FOR PRODUCING REFRACTORY BRICK
Document Type and Number:
WIPO Patent Application WO/2011/093020
Kind Code:
A1
Abstract:
Disclosed is a composition that is for refractory brick and that combines a binding agent for binding and a coated refractory aggregate prepared by coating the surface of a refractory aggregate with a coating layer comprising a binding agent for coating. Because the surface of the refractory aggregate is coated with the coating layer comprising the binding agent for coating, the binding agent for binding is able to bond the refractory aggregate together via the coating layer comprising the binding agent for coating, and it is possible to solidly bond the refractory aggregate together by means of the bond between both binding agents. Also, it is possible to form a char layer adhered to the surface of the refractory aggregate by means of the binding agent for coating on the surface of the refractory aggregate being fired. This char layer exerts an effect as a cushioning layer with respect to sudden heating.
