Abstract

The invention discloses a coal ash thermal retardation and heat insulation fireproof plate as well as a production method thereof. The coal ash thermal retardation and heat insulation fireproof plate consists of a phenol formaldehyde foam plate layer (1) and a coal ash layer (2). The coal ash thermal retardation and heat insulation fireproof plate is characterized in that the coal ash layer blended with fireproof resin is hot-pressed on one surface of the phenol formaldehyde foam plate. The production method comprises the following steps: firstly, materials are prepared in parts by weight: 1000 parts of coal ashes, not less than 100 parts of formaldehyde phenol resin or melamine resin, and 10 to 30 parts of solidifying agent hexamethylene tetramine; secondly, the components are evenly blended, and poured into a mould, and flattened; thirdly, the phenol formaldehyde foam plate is put into the mould; and fourthly, temperature and pressure are increased on a hot pressing machine. Coal ashes are selected as the raw material in the invention, and are formed after being burnt at a high temperature, and can bear the high temperature of hundreds of Celsius degrees, the coal ashes are heated, pressed and shaped after a bonding agent and a solidifying agent are added, and the coal ash thermal retardation and heat insulation fireproof plate has the advantages of high temperature resistance, non distortion, light mass, high intensity and fire prevention, and the purpose of the invention is completely achieved.

Description

technical field [0001] The invention relates to an artificial board and a production method thereof, in particular to a fly ash thermal insulation and fireproof board and a production method thereof. Background technique [0002] As everyone knows, along with people's attention to energy conservation, the products that various insulation materials are made have begun to be used in a large amount indoors and outdoors of building. However, most of the existing thermal insulation products are made of extruded polystyrene board and polyurethane foam board. These two materials will shrink and deform when exposed to heat, and will burn when exposed to fire. Thereby losing heat insulation effect and decorative effect, and even many problems such as falling off from the wall and hurting people may occur. Contents of the invention [0003] The purpose of the present invention is to provide a kind of fly ash thermal insulation and fireproof board and its production method, which is...
