Heat-preservation light wallboard

Abstract

The invention discloses a heat preservation light wallboard, and particularly relates to the technical field of building materials. The heat preservation light wallboard comprises a plate body, wherein the bottom of the plate body is provided with a first face plate, the bottom of the first face plate is provided with a first strip-shaped groove, one side of the plate body is provided with a tenon, the other side of the plate body is provided with a tenon groove, a sandwich layer is arranged in the plate body, a plurality of inflatable bags are arranged in the sandwich layer, a through hole isformed in the front side of the sandwich layer, a second face plate is arranged at the top of the plate body, and a second strip-shaped groove is formed in the top of the second face plate. Accordingto the heat preservation light wallboard, the sandwich layer is positioned between the two face plates and forms an integrated board body with the two face plates by rolling or bonding or pouring, the sandwich layer is a polyurethane foaming light board and achieves good heat preservation and moisture-proof effects, the sandwich layer is provided with the inflatable bags, the weight of the sandwich layer is further reduced, the tenon and the tenon groove on the two sides of the board body can be used for splicing a plurality of wallboards together conveniently, and the heat preservation lightwallboard is compact and firm in structure, good in heat preservation effect, and light-weight and practical.

Description

technical field [0001] The invention relates to the technical field of building materials, and more specifically, the invention relates to a heat-insulating lightweight wallboard. Background technique [0002] With the rapid development of the construction industry and the gradual improvement of people's living standards and energy conservation awareness, building energy conservation has become an indispensable requirement, and wall insulation is one of the most effective building energy conservation, so it has attracted much attention. In the field of housing construction, users have put forward new requirements for the use of partition boards. In the existing technology, various new types of walls have been developed at home and abroad, especially the prefabrication of new building materials hollow partition boards. Ultra-thin, large-scale, light-weight, and functional structures can better meet the fast-paced and assembly-oriented requirements of modern buildings. The th...
