Description

A kind of white foam glass
Technical field
The present invention relates to a kind of New Building Materials, particularly a kind of white foam glass.
Background technology
New Building Materials and wall thermal insulating system propose higher requirement, it is desirable to there should be good heat-insulating property, There are prominent resistance to compression, tension, ageing resistace again；There should be reliable barrier propterty, fundamentally block up exhausted disaster hidden-trouble, again There is water proof anti-seepage, the permanent characteristic of service life；Should be green, it is nontoxic again；Conventional outer wall should be avoided Heat-insulation system complex procedures, it can not monitor, the unwarranted problem of quality, process is simple and direct again, is easy to construct, and quality is guaranteed. Existing foam heat-insulating board in the market, protected by foam made of base material of high-molecular organic materials such as plastics, rubber Warm sheet material.
External-wall heat-insulation material, generally have claimed below：Relatively low thermal conductivity factor, preferable thermal stability and hydrophobicity, Stronger gas permeability, it can effectively prevent from causing the generation of wall internal condensation phenomenon when vapor from migrating；With higher Freeze-thawing resistant ability, weatherability, ageing-resistant performance；For basic unit's deformation with stronger adaptability, can be at first Phenomenon interior that distortional stress is transmitted and discharged, that protection surface layer will not fall off, ftracture；With higher fire resisting etc. Level, occur that during naked light substantial amounts of poison gas will not be given out, when a fire, can effectively prevent the sprawling of the intensity of a fire.
At present, polystyrene foam warming plate fire resistance is poor, is also easy to cause fire, and intensity is relatively low in addition, easily damage It is bad.Moreover, when the wall thermal insulating fire proofing material of prior art is used in external wall surface of storied building, unsightly, generally require to finish fireprotection layer, Decoration of exterior wall is done again, makes cost of a building higher.The present invention for unsightly with cost it is high the problem of, propose a kind of white foam glass Glass plate.
The content of the invention
The invention provides a kind of white foam glass heat-insulating material, and raw material use sillico aluminate glass powder, with lime Stone is foaming agent, mixes appropriate auxiliary additive and carries out decolorization, is formed through batch mixing, preheating, foaming, cooling, annealing.Mesh The expansion for being to make full use of lime stone, and the effect of decolorising agent, can while white foamed glass is obtained The color of the outward appearance of high whiteness is enough obtained, can also reduce density, improves thermal and insulating performance, and then improves quality of materials, together When reduce cost.
Technical scheme is as follows：
A kind of white foam glass, it is characterised in that the glass bag contains solvent and at least one decolouring component：Should Solvent includes：About 70-76 moles % SiO2；About 5-9 moles % CaO；18 moles of % to about 22 moles of % Al2O3； About 1-2 moles % SnCl2；At least one decolouring component includes：A) it is more than 0 mole of % to about 5 moles of % NiO；And/or B) it is more than 0 mole of % to about 4 moles of % Se.
