Abstract

The invention discloses a novel flame-retardant hollow wallboard and a preparation method thereof. The preparation method comprises the steps that extrusion is conducted through a hollow board extruder, concave portions and convex portions are arranged alternately on the upper surface and the lower surface of a hollow board, the concave portions of the upper surface and the lower surface are filled with magnesium powder paste and sealed, two layers of glass fiber gridding cloth are laid on the upper surface and the lower surface correspondingly, and screeding is conducted on the magnesium powder paste; and in addition, supporting racks are additionally arranged in the interior hollow space. According to the flame-retardant hollow wallboard, on the premise that the partition function of the wallboard is guaranteed, the light weight property, the sound insulation property, the anti-aging property, the thermal insulation property, the flame-retardant property and the like are improved, the cost can be reduced, and the environment protection requirements of sustainable development are met. The preparation method of the flame-retardant hollow wallboard is simple and can be widely used for building wall construction under various conditions, and industrialization can be achieved easily.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a novel flame-retardant hollow wallboard and a preparation method thereof. Background technique [0002] At present, the building structure is a load-bearing system composed of walls and floors. The wall is not only a load-bearing member, but also a room partition. It is the most commonly used and economical structural form in residential buildings. The disadvantage is that the flexibility of indoor layout is poor. In order to overcome this disadvantage, the requirements for lightweight, flame retardant, heat preservation and sound insulation of walls are getting higher and higher. [0003] The invention relates to the preparation of a novel flame-retardant hollow wallboard. The method adopts a hollow extrusion process, uses polyvinyl chloride as a base material, has alternate convex and concave surfaces, and seals pasty magnesium powder in the recesses. The flame-retardant ho...
