Flame retardant thermal insulation decorative block for exterior wall

Abstract

The invention discloses an outer-wall inflaming-retarding and heat-preservation decoration block which is composed of a cover plate and an outer frame body with an upward opening. The inner edges of the top ends of a front side plate, a rear side plate, a left side plate and a right side plate of the outer frame body are respectively provided with one or more trapezoid embedding grooves, wherein openings in the upper ends of the trapezoid embedding grooves are larger than openings in the lower ends of the trapezoid embedding grooves. The edges of the front side wall, the rear side wall, the left side wall and the right side wall of the cover plate are respectively provided with one or more trapezoid embedding blocks. The trapezoid embedding blocks with the large upper ends and the small lower ends and the trapezoid embedding grooves are used in a matched mode. The outer frame body is covered with the cover plate to enable a closed heat preservation and insulation cavity to be formed between the cover plate and the outer frame body. Outer frame body reinforcing ribs used for supporting the cover plate are arranged at the positions, on the heat preservation and insulation cavity, of the outer frame body. Cover plate reinforcing ribs for strengthening adhesive force among the cover plate, the outer frame body and a building outer wall are arranged on the outward face of the cover plate. The outer-wall inflaming retarding and heat preservation decoration block has the advantages of being good in heat preservation and insulation effect, excellent in fireproof performance, resistant to flames and water, high in intensity, not prone to breaking, environmentally friendly, easy to manufacture, long in service life and the like.

Description

technical field [0001] The present invention relates to building materials, in particular to a flame-retardant and heat-insulating decorative block for exterior walls. Background technique [0002] With the development of the construction of a conservation-oriented society, the requirements for the thermal insulation performance of various industrial and civil buildings are also getting higher and higher. Not only the building thermal insulation materials are required to have good thermal insulation performance, but also the It has high strength and light weight, and is convenient for construction. Building decoration materials are no exception. At present, the insulation materials used include air-entrained concrete, hollow brick, perlite, benzene board, etc. These materials can achieve a certain insulation effect, but the insulation effect is still not ideal, and there are many materials used in construction, complex construction, and benzene. The disadvantages of the bo...

Problems solved by technology

In recent years, with the improvement of fire safety requirements and the demand of the market, a fireproof aluminum-plastic composite panel has appeared on the market, which is composed of an upper aluminum plate, a middle core material layer and a lower aluminum plate. The composite plate of this structure has good thermal insulation effect. , light weight, convenient construction, etc., but its manufacturing is complicated, high cost, poor heat insulation and fire prevention performance, and does not have the effect of heat preservation and waterproof
