Description
Technical field
The present invention relates to building brick, particularly a kind of non-bearing heat-preserving brick.
Background technology
At present building constructions adopts skeleton construction more, Highrise buildings particularly, and body of wall generally uses concrete hollow block or hollow brick to assemble and forms.Existing concrete hollow block or hollow brick heat insulation effect are poor; Therefore body of wall assemble the back wall face or interior metope also to smear certain thickness thermal insulation mortar or outside paste warming plate; Loaded down with trivial details, the long construction period of not only constructing; And the easy hollowing cracking of metope, have a strong impact on heat insulation effect, and thermal insulation layer is short work-ing life; The particularly outer styrofoam fire retardant performance that pastes is poor, just can burn and discharge a large amount of toxic gases in case run into naked light, brings great potential safety hazard.
Summary of the invention
It is high that the technical problem that the present invention will solve provides a kind of ultimate compression strength and fire-protection rating, insulation, good flame retardation effect, and easy construction, quick has the phase transformation performance and is suitable for the non-bearing heat-preserving brick of building enclosure for building.
Non-bearing heat-preserving brick involved in the present invention; Consist of according to the volume percent raw material: haydite 35%～45%, glass bead 20～25%, float stone or slag 10～15%, cement 8～12%, flyash 3～5%, lime 3～5%, FTC phase-changing energy-storing lagging material 2～3%, gypsum 2～3%, asbestos or rock wool 1～3%, admixture 1～2%, described admixture is made up of for 1～2 part 3～4 parts of hardening accelerator, 3～4 parts of air entrapment agents, 1～2 part of water reducer and hydrophober according to the parts by weight meter.
Particle diameter is 5-10mm after above-mentioned float stone or the slag fragmentation, and the length of asbestos or rock wool is 5-10mm.
Above-mentioned raw material consists of according to volume percent: haydite 39%, glass bead 22%, float stone 13%, cement 10%, flyash 4%, lime 4%, FTC phase-changing energy-storing lagging material 2.5%, gypsum 2.5%, asbestos 2% and admixture 1%, described admixture is made up of for 1.5 parts 3.5 parts of hardening accelerator, 3.5 parts of air entrapment agents, 1.5 parts of water reducers and hydrophober according to the parts by weight meter.
In the raw material of the present invention: haydite is bigger owing to specific density in the moulding process of brickmaking as a kind of light-weight aggregate, therefore in the process of vibrating, can sink to forming the link of relative heavy aggregate gradually, with the ultimate compression strength that improves this non-bearing heat-preserving brick greatly.Float stone or slag can increase the degree of compactness of brick as fine aggregate, improve the mechanical strength of brick.The density of glass bead is lighter relatively, can play the effect of filling, insulation, thermal insulation, Fang Huo ﹑ sound-absorbing as light filler.Cement, lime and gypsum are mainly as consolidating material and packing material.Flyash plays workability of regulating concrete and the effect that admixture is played a role.Asbestos or rock wool play the cracking resistance effect, and can reduce dried shrinking percentage, increase the folding strength of brick.FTC phase-changing energy-storing lagging material is a kind of phase change material, has heat absorption, accumulation of heat and heat release function.Hardening accelerator in the admixture can shorten cement setting time, improves early strength; Air entrapment agent in the admixture can be increased in the closed pore number of bubbles that forms in the brick, improves heat insulation effect, and improves the workability of mixture; Water reducer and hydrophober can reduce the water-intake rate and the relative moisture content of this non-bearing heat-preserving brick.The advantage of the non-bearing heat-preserving brick of processing with above-mentioned raw materials is: ultimate compression strength and folding strength significantly improve, and ultimate compression strength can reach 7.5Mpa, and folding strength can reach 2.2 Mpa, and fire-protection rating is high, reaches the A level; Insulation, fire-retardant, soundproof effect good, need not to do exterior-wall heat insulation with the body of wall of its construction again, can shorten construction period, simplify construction technology, reduce building cost; Density is little, in light weight, and density can be made into all kinds and specifications such as solid brick, perforated brick near 1/3rd of sintered common clay brick; Not only be convenient to construction; And can reduce bearing capacity of foundation soil, and be suitable for building enclosure for building, be particularly suitable for Highrise buildings and use.
