Composite insulation wall board

Abstract

The invention discloses a composite thermal insulation wallboard, belonging to the field of building materials, comprising a glass magnesium board, an insulation layer bonded to the lower surface of the glass magnesium board, and an aluminum board bonded to the upper surface of the glass magnesium board; the lower surface of the aluminum board has a A plurality of ribs arranged at intervals in the length direction, with quick-setting cement between the aluminum plate and the glass magnesium plate, and the quick-setting cement is filled into the space between adjacent ribs; the composition of the insulation layer includes: phenolic resin, Flame retardant, foaming agent, curing agent, reinforcing agent, and the slurry formed by stirring the above components is injected into the mold of the molding machine and solidified; the fast-setting cement is injected between the aluminum plate and the glass magnesium plate, and after curing, it is combined with heat preservation layer bonding. The overall strength of the wallboard is high, the resistance to external forces is excellent, and the bonding ability is strong. The insulation layer enables the wall to maintain the water-air balance in various climates, and has functions such as heat insulation, water seepage prevention, and fire prevention.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a composite thermal insulation wallboard. Background technique [0002] With the development of society, the wall reform policy has been implemented; the concrete can be presented as follows: due to the popularization of high-rise buildings, there are fewer and fewer buildings with masonry structures, that is, the use of "bricks" as load-bearing walls is less and less, then Instead, wall panels. [0003] At present, there are more and more types of wall boards on the market, among which gypsum or cement lightweight partition boards, color steel plates, steel wire grid foam boards, gypsum boards, PC large boards, and horizontal hole concrete wall boards are more widely used. , activated carbon walls and new partition boards, etc. In addition to good thermal insulation performance, good strength and external force resistance are also required. At present, light weight and suitab...

Problems solved by technology

In addition to good thermal insulation performance, it also needs to have good strength and external force resistance. At present, it usually achieves light weight and suitable thermal insulation performance, but its overall strength and external force resistance are not good enough.
