Description

A kind of preparation method of expanded perlite thermal-nsulation brick
Technical field
The invention discloses a kind of preparation method of expanded perlite thermal-nsulation brick, belong to building material technical field.
Background technology
Insulating brick, a kind of novel product of alternative ceramic tile, is primarily adapted for use in toilet, kitchen, television background wall, crouches Room, exterior wall etc..And pattern is beautiful, multi-size, can arbitrarily cut, section is neat.Pearlite insulation brick is a kind of new builds Build finishing material, have thermal conductivity factor is low, performance is stable, lightweight, fire prevention, nontoxic, tasteless excellent characteristic, can be widely applied to Office building, hotel, hotel, shop, villa, fireproof heat insulating, sound insulation isolation, the partition wall of household private residence fitting-up engineering are built by laying bricks or stones Non-load bearing wall, material used for filler wall;Apply also for boiler liner, hot wind inner lining of furnace, drying chamber, drying tunnel, flue, HVAC air passage, freezer Deng to the higher place of fire protection requirement and position isolation material is kept the temperature as fire-proof and thermal-insulation.
Due to a variety of inorganic incombustible materials such as selection system expanded perlite, high temperature resistant binder, then through scientific formula and elder generation It is prepared into technology, the A1 grades of fire-protection rating technologies as defined in National Fire construction material supervision and inspection that comply fully with refer to Mark, more than 1100 DEG C of fire resisting high temperature;Pearlite insulation brick is particular about the toxin such as scientific formulation, no any chlorine formaldehyde due to selection and is released Volatilization is put, complies fully with the safe level-one of flue gas toxity as defined in National Fire construction material supervision and inspection(AQ1)Technical requirements, are Preferable household interior decoration partition wall builds safe and healthy thermal insulation material by laying bricks or stones;Good pearlite insulation brick does not use traditional oxidation The halogen species such as magnesium magnesium chloride magnesite and the preparation process fallen behind, will not corrosion metals and timber, and possess fabulous waterproof and hate Water-based energy and moisture-proof role;With traditional architecture with clay brick the novel and unique such as unrivaled light thermal-insulation superiority Can, its superior intension quality and rational cost performance obtain the praise of fireproof heat insulating industry and decorations people from all walks of life.But Be at present traditional insulating brick also there are heat-insulating property it is bad the problem of, therefore also need to study it.
The content of the invention
The present invention solves the technical problem of:For conventional vacuum brick heat-insulating property it is bad the problem of, there is provided one The preparation method of kind expanded perlite thermal-nsulation brick.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is:
