Foam heat-insulating brick for roof

Abstract

The invention discloses a foam heat-insulating brick for a roof.The brick is provided with a foam layer and a surface layer which achieve layer binding; the foam layer is prepared from, by weight, 625-930 parts of cement, 625-860 parts of dry sand, 1.8-2.2 parts of a foaming agent and 400-560 parts of water; the surface layer is prepared from, by weight, 120-128 parts of cement, 265-280 parts of small stones, 360-385 parts of fine sand and 96-105 parts of water.The foam heat-insulating brick is provided with the foam layer and the surface layer, the foam layer is mainly prepared from the cement, the dry sand, the foaming agent and the water in appropriate proportion, the surface layer is mainly prepared from the cement, the small stones, the fine sand and the water in appropriate proportion, preparation is easy, the cost is low, no pollution is generated, and the heat insulating effect is good.The foam layer components accounting for 5%-10% of the total weight of the surface layer are preferably added in the surface layer, therefore, connection between the surface layer and the foam layer can be greatly enhanced, the strength of the heat-insulating bricks can be improved, the firm and durable advantages are brought, and a certain benefit can be brought to the heat-insulating performance of the foam heat-insulating brick.

Description

technical field [0001] The invention relates to the field of building bricks, in particular to a roof foam heat insulation brick. Background technique [0002] At present, there are many types of building materials used for heat insulation. Among them, the foamed concrete roof insulation layer is more commonly used for roof insulation. The foam concrete roof insulation layer adopts the method of on-site pouring, that is, the roof Direct construction of foam concrete insulation layer. Specifically, it uses concrete mortar or cement mortar to add foam to make foam mortar or foam cement mortar, and then constructs it on the roof. After curing and hardening, a thermal insulation layer integrated with the roof is obtained. Due to the low strength of the cast-in-place concrete insulation layer, its high water absorption rate, and poor waterproofing, it cannot be directly exposed to the outside. It is also necessary to set up protective layers, waterproof layers and other structur...
