Composite wall plate with waste textile fibre reinforced concrete side surface and its producing method

Abstract

The composite wall plate has one middle layer of porous plastic, rock wool, honeycomb structure, foamed concrete or other heat insulating and sound isolating material and waste fiber reinforced concrete surface layers combined firmly via vibration and rolling. The present invention features that the surface layer is formed by soaking felt of waste textile fiber and at least one outer alkali resisting glass fiber cloth with cement slurry. During soaking, the felt and glass fiber cloth is extruded to eliminate air and the cement slurry is vibrated with a inserted vibrating pump. The wall plate has strong bending resistance, no rust and low cost, and the present invention solves the waste fabric disposing problem.

Description

technical field [0001] The invention relates to a composite wallboard of waste textile fiber-reinforced concrete sides (composed of inner and outer sides and middle insulation materials). The invention also relates to a method of manufacturing the wallboard. Background technique [0002] There are many types of composite wall panels in use today, with different structures. A more advanced example is a composite wallboard composed of steel fibers and plastic fibers oriented to reinforce the concrete side and intermediate insulation materials. The panels are lighter than previous panels, have better thermal and acoustic properties and are easier to install. But this board has two deficiencies, the one, because need steel fiber and plastic fiber especially need more complicated equipment, so manufacturing cost is relatively high (the selling price is just high); [0003] More importantly, objectively, the wallboard cannot use waste textile fibers. The di...

Problems solved by technology

However, because it needs a complicated production line to evenly mix the waste fibers processed into cotton-like cement, and a huge pressure must be applied when forming, it takes a certain time for the board to harden, and it takes a long time to occupy the equipment, so the production cost is high and the price is also low. At the same time, in order to make the fibers mix well in the slurry without tangling into agglomerates, the length of the fibers has to be controlled, which loses the bending strength, so the bending strength of the two sides is poor; in addition, the metal keel is easy to rust , especially in the humid environment in the south of the Yangtze River, the quality is even more difficult to guarantee
