Description

Lignin light wallboard

Technical Field

The utility model relates to the technical field of wallboards, in particular to a lignin light wallboard.

Background

The traditional wall body building mainly uses clay bricks and cement blocks as main raw materials, and the manufactured wall body is large and heavy, and occupies a considerable part of building use space; poor heat preservation, heat insulation, sound insulation and water resistance; the impact resistance is low, and the wall surface is often cracked, so that the quality and the use of the building are affected; the construction is inconvenient, the construction period is long, and the construction cost is high; the production energy consumption is high, and the realization of the energy conservation and emission reduction targets is not facilitated.

The light wallboard material is a novel energy-saving material and has the characteristics of light weight and high strength. In order to simultaneously realize the advantages of environmental protection, energy saving, heat preservation, sound insulation, water and fire prevention, thin wall, earthquake resistance, convenient construction and the like, two or more materials are generally compounded to prepare the light wall material. However, the composite wallboard using inorganic heat-insulating materials such as rock wool, foamed perlite, foamed ceramics and foamed glass as the filling layer has large dead weight and poor heat insulation performance, and is not beneficial to realizing energy conservation of buildings. Composite wall boards using polystyrene foam, polyurethane foam, phenolic foam and other organic materials as filling layers are limited in application because of low fireproof safety performance. Polyurethane has the excellent performances of light weight, heat insulation, sound absorption, shock resistance, water resistance, corrosion resistance and the like, and is an ideal light structural material and energy absorption material. However, polyurethane is an organic high molecular compound, has poor fireproof performance and needs to be subjected to flame retardant modification; and polyurethane has lower strength, and can not meet the use requirement in a plurality of special occasions with high strength requirements (for example, as structural materials and matched materials thereof), and the mechanical strength of the material needs to be improved by various means so as to achieve the purpose of reinforcement. Therefore, new lightweight wall materials with high quality and high performance are urgently needed to replace traditional wall materials in the building market at present.
