Abstract

The invention belongs to the technical field of production of partition boards and especially provides a high-strength sound-insulation honeycomb paper wall board and a preparation method of same. Thehoneycomb paper wall board is composed of a honeycomb core layer as an inner layer and surface layers, which are formed by performing vertical mold pouring on the two surfaces of the inner layer. A reinforcing material, which is prepared from raw materials including polypropylene resin, locust tree wood dust, polyester fibers, ethylene-vinyl acetate copolymer, aluminum powder, bentonite, cement and water, is used for coating the surfaces of the honeycomb core layer; and then the surface layers are made from cement, SiO2 micropowder, river sand, cobblestone powder, aluminum hydroxide, a defoamer and water; the surface layers are bonded to and fixed with the processed honeycomb core layer and finally the product is subjected to maintenance treatment. The honeycomb paper wall board has highstrength, is good in sound-insulation property and has heat insulation function, is free of swelling and cracking problems, is free of pollution, is safe and environment-friendly, is mainly used for indoor insulation for entertainment venues and office zones, and has broad application prospect.

Description

technical field [0001] The invention belongs to the technical field of partition wall board preparation, in particular to a high-strength sound-insulating honeycomb paper wall board. Background technique [0002] Honeycomb paper is a new type of sandwich structure that connects corrugated base paper into countless hollow three-dimensional regular hexagons by glue bonding to form an integral force-bearing part-paper core, and glues face paper on both sides. Environmentally friendly and energy-saving materials; it has the characteristics of light weight, low price, high strength, and recyclability. It is widely used in construction industry, packaging and transportation industry, funeral industry, agriculture, etc. Gradually deepening, green wall materials are becoming more and more popular in the market. [0003] For example, a paper honeycomb sandwich inner partition wall panel disclosed in patent CN200510134265.1 adopts a special plate-type composite structure, and the ove...
