Abstract
The invention relates to the technical field of building materials and especially relates to an additive agent suitable for calcium silicate boards, which is prepared from following raw materials, by weight, 2-6 parts of sodium aluminate, 1-4 parts of quick lime, 2-5 parts of gypsum and 2-6 parts of sodium silicate or potassium silicate. The additive agent is toxic-free and pollution-free, can greatly increase adding quantity of fly ash, mineral residue and such waste residues in the calcium silicate boards, significantly improves strength, heat insulation and dampness proofing performance of the calcium silicate boards, can reduce cost, and is easy and convenient to use.
Description
Technical field
The present invention relates to building material technical field, particularly a kind of admixture being applicable to calcium silicate board.
Background technology
Calcium silicate board is main consolidating material with siliceous-calcareous material, with the loose staple fibre such as inorganic mineral fiber or cellulosic fibre for strongthener, through slurrying, shaping, and accelerate curing reaction in High Temperature High Pressure saturated steam, form Calucium Silicate powder gel and the sheet material made.Abroad, in order to produce the calcium silicate board with superperformance, in silico-calcium base material, mainly add a certain amount of expensive organic emulsion (as butadiene-styrene emulsion, silane coupling agent, methylcellulose gum etc.) or add high-elastic mould carbon fiber replace fibrous magnesium silicate, obtained calcium silicate board is expensive.
Summary of the invention
The invention provides a kind of admixture being applicable to calcium silicate board, raw material is easy to get, cheap, can significantly improve the intensity of calcium silicate board, the performance such as heat insulation, moistureproof, obtained functional, cheap calcium silicate board.
The technical solution used in the present invention is: a kind of admixture being applicable to calcium silicate board, is made up of the raw material of following weight part: sodium aluminate 2-6 part, unslaked lime 1-4 part, gypsum 2-5 part, water glass or potassium silicate 2-6 part.
Be applicable to an admixture for calcium silicate board, preferably, be made up of the raw material of following weight part: sodium aluminate 5 parts, unslaked lime 3 parts, 3 parts, gypsum, water glass or potassium silicate 5 parts.
Compared with prior art, the invention has the beneficial effects as follows: admixture of the present invention is nontoxic, pollution-free, the incorporation of the waste residue such as flyash and slag in calcium silicate board can be increased considerably, significantly improve the intensity of calcium silicate board, the performance such as heat insulation, moistureproof, reduce costs; And easy handling, it is convenient to be suitable for.
Embodiment
Below in conjunction with specific embodiment, the invention will be further described.Following each embodiment just preferably illustrates citing, does not limit protection scope of the present invention.
embodiment 1
Be applicable to an admixture for calcium silicate board, be made up of the raw material of following weight part: sodium aluminate 2.5 parts, unslaked lime 1.8 parts, 2 parts, gypsum, water glass 3 parts.
embodiment 2
Be applicable to an admixture for calcium silicate board, be made up of the raw material of following weight part: sodium aluminate 5 parts, unslaked lime 3 parts, 3 parts, gypsum, water glass 5 parts.
embodiment 3
Be applicable to an admixture for calcium silicate board, be made up of the raw material of following weight part: sodium aluminate 6 parts, unslaked lime 3.7 parts, 4 parts, gypsum, potassium silicate 6 parts.
In order to further illustrate beneficial effect of the present invention, now carry out calcium silicate board performance test.
test 1
Take each feed composition by the weight part of above-described embodiment 1, mix obtained admixture of the present invention; Mix admixture of the present invention by 2% of solid material weight when preparing calcium silicate board, stir through stirrer, obtained calcium silicate board.
test 2
Take each feed composition by the weight part of above-described embodiment 2, mix obtained admixture of the present invention; Prepare calcium silicate board method with test 1.
test 3
Take each feed composition by the weight part of above-described embodiment 3, mix obtained admixture of the present invention; Prepare calcium silicate board method with test 1.
contrast test
Prepare without mixing admixture of the present invention in calcium silicate board process, obtained calcium silicate board.
Test to above-mentioned each group the calcium silicate board obtained and carry out performance test (with reference to JCT564.2-2008 fiber reinforced calcium silicate board), obtain specific performance parameter as shown in table 1.
table 1
Can be found out by table 1: the calcium silicate board mixing admixture of the present invention: 1. folding strength is all improved significantly.2. water ratio all obviously reduces, and moisture absorption moistureproofness improves.3. thermal conductivity is all less, and effect of heat insulation is better.
The admixture that the present invention is applicable to calcium silicate board is nontoxic, pollution-free, can significantly improve the intensity of calcium silicate board, the performance such as heat insulation, moistureproof, reduce calcium silicate board production cost; And easy handling during preparation, it is convenient to be suitable for.
