Problems solved by technology

The material has some disadvantages: 1. The heat insulation effect is not ideal. The heat insulation effect of vermiculite will drop sharply at high temperature, because after pressing, there will be some irregular large pores between the vermiculite and vermiculite. thereby reducing insulation against radiant heat
2. The water absorption rate of vermiculite is very high, and it will cause a decrease in strength and a decrease in heat insulation effect after being exposed to moisture

Abstract

The invention relates to a vermiculite-nanometer powder composite heat insulation material. The vermiculite-nanometer powder composite heat insulation material comprises, by weight, 30 to 70 parts ofexpanded vermiculite, 20 to 70 parts of nanometer powder, 30 to 50 parts of a binder and 10 to 20 parts of an infrared opacifier. According to the invention, since gaps among the vermiculite is filledwith the nanometer powder, a heat transfer path is prolonged and macropores are made finer, and thus, heat insulation performance is improved; the infrared opacifier is introduced to improve radiantheat insulation effect; and filling of the nanometer powder improves the strength of the material and reduces water absorption rate.

Description

technical field [0001] The invention belongs to a heat-insulation ring used as an electric furnace periphery, and in particular relates to a heat-insulation material compounded with vermiculite and nanometer powder. Background technique [0002] At present, the thermal insulation material of vermiculite plus water glass binder is used to make the thermal insulation ring around the electric furnace. The material has some disadvantages: 1. The heat insulation effect is not ideal. The heat insulation effect of vermiculite will drop sharply at high temperature, because after pressing, there will be some irregular large pores between the vermiculite and vermiculite. This reduces the insulation against radiant heat. 2. The water absorption rate of vermiculite is very high, and the strength will decrease and the heat insulation effect will decrease after being damp. Contents of the invention [0003] The purpose of the present invention is to provide a thermal insulation materi...
