Cement-based fiber-reinforced fireproof heat-preservation plate and preparation process thereof

Abstract

The invention discloses a cement-based fiber-reinforced fireproof heat-preservation plate. The cement-based fiber-reinforced fireproof heat-preservation plate is characterized by comprising a core layer, wherein the upper surface and the lower surface of the core layer are respectively provided with surface layers; the core layer is a cement gelatinizing layer; and furthermore, the cement gelatinizing layer contains non-uniformly distributed expanded granules. The invention also provides a preparation process of cement-based fiber-reinforced fireproof heat-preservation plate, comprising the following steps of: measuring raw materials; stirring materials; carrying out extrusion forming; and adhering a gridding cloth. The invention completely meets the requirement for fire resistance of an outer wall heat-preservation plate, has low heat transfer, can meet the requirements for heat preservation and heat insulation of buildings and has high anti-crush anti-breaking strength; the raw materials can not be combusted at high temperature without releasing poisonous gases, belong to safe environmental-friendly materials and are all from the nature without corrosivity or radioactivity; and the cement-based fiber-reinforced fireproof heat-preservation plate disclosed by the invention has the advantages of light weight, easy carrying, good cutting, easy construction, good compatibility and strong binding power of a wall body.

Description

technical field [0001] The invention belongs to the field of fireproof and thermal insulation boards for buildings and the production process of the fireproof thermal insulation boards, in particular to a cement-based fiber-reinforced fireproof thermal insulation board and its preparation process. Background technique [0002] At present, the development of society is inseparable from the construction industry. In modern society, architecture largely shows the development of a place. As time goes by, people's requirements for the quality of buildings are getting higher and higher. For a building, thermal insulation and fire protection are two important technical considerations, and they are also the difficulty and focus of research and development in the construction industry. Traditional insulation boards use polystyrene foam boards, polyurethane foam boards, etc. These insulation materials have excellent thermal insulation performance, light weight, and are easy to insta...

AI Technical Summary

Problems solved by technology

In this way, first, the fireproof structure is treated separately, which increases the amount of construction and the cost of construction, the production process is complicated, the quality increases, and it cannot be mass-produced in a factory; the second is that even if the fireproofing treatment is done on the insulation board , still not up to the A-class fire protection standard stipulated by the state
