Embodiment Construction

[0040] In order to enable those skilled in the art to better understand the inventive concept and specific application of the present invention, the technical solutions of the present invention are explained and illustrated in detail below in conjunction with preferred embodiments. Of course, the listed embodiments do not limit the protection scope of the present invention. To limit.

[0041] Part I Preparation of Graphite Modified Polystyrene

[0042] By heating and pressing, under the action of steam and foaming agent (contained in the raw material), the steam condenses in the internal tissue space after encountering graphite polystyrene, releasing heat to soften graphite polystyrene and make it foam It expands, increases in volume, and changes in density accordingly. After curing and shaping, graphite-modified polystyrene suitable for wallboards is obtained. The specific preparation method is as follows:

[0043] Step 1, prepare raw materials: pull the commercially availa...

Abstract

The invention discloses a graphite modified polystyrene solid lightweight concrete wallboard and a preparation method thereof, the wallboard is prepared by taking a steel wire net rack and glass fiber gridding cloth as a framework, pouring a mixture and then solidifying, and the mixture is composed of cement, lightweight aggregate, a filler, a compound additive, graphite modified polystyrene and water. The graphite modified polystyrene is formed by foaming graphite polystyrene twice under specific conditions. The graphite modified polystyrene solid lightweight concrete wallboard can meet the requirements of light weight and high strength at the same time, is formed through one-time pouring, is good in overall gelling and curing effect, free of panel compounding, free of shelling and separation, good in integrity and stability, and synchronous with a building in service life; and secondary decoration is facilitated, slotting and pipe arrangement can be carried out at will, and cracking is avoided. The fire resistance is good, the combustion grade of the wallboard is grade A, and the fire endurance is more than 4 hours.

Description

technical field [0001] The invention relates to the technical field of prefabricated prefabricated interior wall panels for buildings, in particular to a graphite-modified polystyrene solid lightweight concrete wall panel and a preparation method thereof. Background technique [0002] The building walls were built with red bricks and shale porous bricks in the early days. Due to the damage to the ecology and the high bulk density affecting the building load requirements, the use of the two has been restricted. Later, cement hollow bricks and aerated concrete blocks appeared on the market. The advantages of cement hollow bricks are: The cost is low, the strength is high, and its disadvantages are relatively obvious, that is, no earthquake resistance, heavy weight, and poor hanging force; the advantages of aerated concrete blocks are light weight and good heat insulation effect, and the disadvantages are low strength, high water absorption, and impact resistance. Poor, low imp...
