Self-heat insulation brick and self-heat insulation block, and production technologies thereof

Abstract

The invention relates to a self-heat insulation brick or block and a production technology thereof. The self-heat insulation brick or block is produced through utilizing a cement-based gellant capable of solidifying ultrafine inorganic substances as a base material, treating calcium silicate powder as a primary heat insulation material and compounding with one or more of vermiculite, diatomite and a vitreous bead. The production technology of the self-heat insulation brick or block is carried out through treating present materials as aggregates without changing a present brick making streamline. The self-heat insulation brick block is characterized in that the brick or block comprises 1-2wt% of the cement-based gellant, 8-20wt% of the calcium silicate powder, 0-5wt% of a vermiculite particle or diatomite or the vitreous bead, 15-30wt% of cement, and 76-43wt% of the materials used at present. The non-bearing self-heat insulation brick block has the characteristics of high heat insulation performance, light weight, strength adjustment according to the design, sound insulation, fire prevention, simple construction and the like. A building built through utilizing the self-heat insulation brick or block satisfies a requirement of 65% energy saving of the building, and realizes the purposes comprising wall heat insulation, A fireproof grade, building structure optimization and life prolongation.

Description

technical field [0001] The invention relates to a non-load-bearing self-insulating brick block made of inorganic materials, which has the characteristics of high thermal insulation performance, light weight, high strength, sound insulation and fire prevention, and simple construction. Buildings built using self-insulating bricks, self-insulating blocks and special insulation mortar for masonry meet the requirements of building energy saving of 65%, and achieve the purpose of wall insulation, fire protection grade A and the same life span of building structures. Background technique [0002] Although existing self-insulating bricks and self-insulating blocks have good thermal insulation effects, they require large investment and complex production techniques. For example, fly ash sintered self-insulating bricks or blocks require heat and consume energy in the production process, which is not environmentally friendly; composite self-insulating blocks have at least two processe...
