Composite light-weight strip plate with high adhesion force and preparation method thereof

Abstract

The invention discloses a composite light-weight strip plate with high adhesion force. The composite light-weight strip plate consists of a foaming core layer and mesh surface layers, wherein each mesh surface layer is compounded to at least one surface of the foaming core layer; an adhesive is coated between the foaming core layer and the mesh surface layer; steel wire nets are embedded into the foaming core layer; the foaming core layer is prepared from the following raw materials and components in parts by weight: 30 to 200 parts of cement substrate, 10 to 200 parts of water, 20 to 50 parts of gypsum, 25 to 50 parts of calcium silicate, 10 to 50 parts of active filler, 0.1 to 1 part of cellulose, 0.1 to 1 part of polyester fiber, 0.05 to 0.2 part of glass fiber, 0.1 to 1.35 part of dispersive latex powder, 0.8 to 1.5 parts of functional additive, 0.5 to 1.5 parts of processing additive, 0.1 to 1 part of hydrogen peroxide, and 0.1 to 1 part of hydrogen peroxide stabilizer. The composite light-weight strip plate has the advantages that by adjusting the raw materials, the components and the proportional ratio of the foaming core layer, after detection, the mechanical property meets the requirement of national standard GB / T 23451-2009 Light-weight Strip Plate for Building Partition Walls; after the hanging force is applied with 1200N load, and is stood for 48h, the gap with width of 0.5mm or more does not exist on the plate surface around the hanging area, and various types of decoration surfaces can be easily paved and attached.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a composite lightweight strip with high adhesion and a preparation method thereof. Background technique [0002] Wall panels are widely used in non-load-bearing wall building materials. Most of them are plastic wall panels or wooden wall panels, and generally have a single-layer structure. Many quality problems will occur during long-term use, such as cracking, water seepage, warping and deformation At the same time, due to the single function of this ordinary wallboard, poor comprehensive performance, poor adhesion and easy to fall, it will be gradually eliminated in the process of people's increasing pursuit of high-quality wallboards. Contents of the invention [0003] The purpose of the present invention is to provide a composite lightweight strip with high adhesion and a preparation method for the composite lightweight strip in order to solve the problem of poor adhesion ...
