Expandable polystyrene (EPS) flame retarding building coreboard and prepared method thereof

Abstract

The invention discloses an expandable polystyrene (EPS) flame retarding building coreboard and a prepared method thereof. The EPS flame retarding building coreboard comprises a substrate layer and a coreboard layer. The substrate layer comprises a lower substrate layer and an upper substrate layer. The surface of the coreboard layer is provided with a reticular fiber layer. The coreboard layer and the reticular fiber layer are fixedly arranged between the lower substrate layer and the upper substrate layer through solidification glue. The surface of the upper substrate layer is provided with a coated plate. The EPS flame retarding building coreboard which is prepared by the above-mentioned method contains polystyrene inside, so that dead weight of materials can be reduced and building intensity can be reduced to achieve an effect of prolonging service life. Affinity of the polystyrene can be enhanced by adding active agents and mixing cement paste can be prevented from being fallen off. Stability of the EPS flame retarding building coreboard in the flame can be enhanced by flame retarding agents.

Description

technical field [0001] The invention relates to a building material, an EPS flame-retardant building sandwich panel and a manufacturing method thereof. Background technique [0002] The materials used in the construction of houses, streets, bridges and other buildings are commonly referred to as building materials. Building materials involve a wide range of materials, such as thermal insulation materials, heat insulation materials, and high-strength materials. [0003] Building materials can be divided into structural materials, decorative materials and special materials. Among the existing building materials, buildings are heat-insulated and fireproof, and gypsum boards, composite boards or foaming materials are often used for the interior and exterior walls of buildings and non-weight-bearing ceilings. [0004] However, the wall and ceiling constructed with the above materials have the problem of uniform load bearing. The concrete wall can prevent flames, but the wall wit...

AI Technical Summary

Problems solved by technology

[0004] However, the walls and ceilings constructed with the above materials have load-bearing problems evenly. The concrete walls can prevent flames, but the walls without the addition of thermal insulation materials cannot be insulated, and part of the cement pouring has uneven strength and density. , it is difficult to achieve the effect of heat insulation

[0005] In addition, various improved polystyrene heat-insulated and flame-resistant panels and composite panels made of these materials can only work against some small fires
