Description
Technical field
The present invention relates to building material field, specially refer to a kind of thermal insulation fire-proof plate, the invention still further relates to the making method of this thermal insulation fire-proof plate with good heat-insulation and heat-preservation fire resistance.
Background technology
Along with the implementation of China's materials for wall innovation with the building energy conservation policy, the development and application of energy-saving building material receives extensive attention.On March 14th, 2011; Fire-fighting general bureau of the Ministry of Public Security puts into effect " about the notice of further clear and definite covil construction heat insulating material for external fire supervision management relevant requirements " public affairs and disappears [2011] No. 65, and it is the material of A level that strict execution covil construction external-wall exterior insulation material adopts the combustionproperty grade.For this reason, it is urgent day by day that the research of inorganic heat preserving and heat insulation material and production seem, the research and development of special mineral-type sheet material have obtained more concern and attention.
At present, domestic mineral-type sheet material kind mainly contains foam cement plate, foamed glass plate, foamed concrete plate, pearlite slab etc.The material of foam cement plate mainly is inorganic coagulation materials such as rapid hardening cement, flyash; Take by weighing material with organic polymer, suds-stabilizing agent, whipping agent etc. by certain proportioning; Foam after stirring at the appointed time in mould; The blank material that foaming is good is maintenance certain hour, excision forming then under certain condition.Its principle is exactly to lean on whipping agent to produce bubble, and the porous air cavity configuration that is produced by bubble can reach certain incubation and thermal insulation function.Its advantage is that production technique is simple, and starting material require low, easy for industrialized production, and fire resistance is good.Shortcoming is that intensity is low, poor dimensional stability, easy truncation arrisdefect at the scene, surperficial hole wall is crisp, thin, with matrix material and coating material combine badly, hidden danger of quality such as hollowing, cracking are arranged.
Foamed concrete has another name called foamed concrete, foamed cement; Be to be main agglutinate with silicate cement or quick hardening sulphoaluminate cement; Flyash, silicon ash etc. are adulterant; An amount of admixture fine sand or lightweight fine particle are aggregate, add the inorganic light weight concrete that organic blowing agent (or adopting mechanical foaming), suds-stabilizing agent etc. are processed.
The foamed concrete warming plate belongs to the cement based porous light-weight material, and the A level is not fired, and good heat insulating is that the ideal external wall is incubated equivalent material outward.Yet, the common foamed concrete warming plate that circulates on the market now, its production technology and performance also come with some shortcomings, and have seriously restricted its large scale application.Its technical difficult points is the accurate metering difficulty of raw material quality and proportioning.Main material commonly used has: aluminosulfate cement, mineral admixture and whipping agent, and self material property fluctuation is bigger, and quality is also unstable.Also have, the volume of subsidiary material such as suds-stabilizing agent, water-resisting agent, organic fibre is little, and the effect that some deviation of weights bring can largely have influence on quality product.
The material of pearlite heat-insulation plate is formed has pearlstone and bubble flower alkali (being commonly called as water glass), the manufacture craft flow process for feed intake, mix and stir, pressing machine moulding and baking operations such as (or natural curings).Its enhancement principle is the pectisation of compression compact moulding and bubble flower alkali; Most perlite can be broken in compression process; Perlite after the fragmentation can significantly reduce thermal property, and bubble flower alkali is industrial chemicals, and its ageing resistance, environmental issue all need to pay attention to.
Summary of the invention
To the performance deficiency of above material, the object of the present invention is to provide a kind of is main thermal insulation fire-proof plate of making and preparation method thereof with the inorganic materials, as above several types of energy-conservation replacement schemes with sheet material.
The object of the invention is realized through following technical scheme: a kind of inorganic thermal insulation fire-proof plate is provided; Staple is expanded and vitrified small ball, high-alumina cement, semi-hydrated gypsum, ordinary Portland cement, high molecular polymer rubber powder, polypropylene fibre, organosilicon moisture repellent, ether of cellulose, water, and forms (weight ratio) according to following mixed:
