Description
Technical field
The present invention relates to building materials technology field, relate in particular to a kind of silico-calcium light wall board, also relate to the manufacture method of this silico-calcium light wall board.
Background technology
The contriver is in the patent No. 200610059751.6, title is in the patent of " calcium silicate plant fibre Light trabs and manufacture method thereof ", a kind of method of making wallboard is disclosed, employed main raw material is vegetable fibre, in the past few years, obtain the approval of society, but such manufacture method exists that raw material is more, complex process, shortcoming that cost is high.
In the prior art, the main raw material that indoor wallboard is used or cement because the setting time of gypsum is shorter, the general usefulness of indoor wallboard be extruding shaping technique, need the long time, so the application of gypsum in the wallboard manufacturing is restricted.
On the other hand, along with building a conservation-minded society, require refuse to take full advantage of, and in the reality, the utilization ratio of industrial residue or on the low side, many refuses that are used as discard, and also can take up room as the waste residue of refuse; In the wallboard manufacture of prior art, mix waste residue often because of the unreasonable intensity that can affect wallboard of technique.
Summary of the invention
Purpose of the present invention is exactly for above-mentioned shortcoming, provide a kind of technique simple, satisfy the silico-calcium light wall board manufacture method that the process time requires, cost is low, also provide a kind of intensity high, not aliquation, do not fall the silico-calcium light wall board of piece, health environment-friendly.
The manufacture method of silico-calcium light wall board of the present invention is achieved in that a kind of manufacture method of silico-calcium light wall board, may further comprise the steps:
A, by weight gets 30-40 parts gypsum, 8-12 parts cement, 50-60 parts cinder powder as raw material for standby, is as first group of raw material;
B, by weight gets 0.01-0.02% retardant of gypsum weight;
C, by weight gets 1.6-2.0% crystal modifier of first group of raw material;
After gypsum and the retardant got added water and fully stir, add again the cement, cinder powder, the crystal modifier that weigh up and fully stir, send in the single-lead-screw extruding briquetting machine namely plastic.
Preferably, used retardant is the mixture of citric acid, Sodium hexametaphosphate 99 and tripoly phosphate sodium STPP.
Preferably, used crystal modifier is the mixture of potassium aluminium sulfate and Trisodium Citrate.
Silico-calcium light wall board of the present invention is the plaster wall sheet material that uses aforesaid method to make.
The invention has the beneficial effects as follows:
1, the wallboard that has used gypsum to make as main raw material can utilize the character of gypsum, can automatically adjust indoor moisture content; When room air was dry, sheet material can discharge moisture; When indoor humidity, sheet material can absorb moisture, plays the effect of regulating air, lives more comfortable;
2, use more cinder powder, can reduce cost, utilization of waste material;
3, the centre adds the setting time that retardant can prolong gypsum, meets the time requirement of extrusion plate;
4, the centre has added crystal modifier, the gypsum sheet material of making is had do not come off, the effect of aliquation not;
5, this silico-calcium light wall board also has high, lightweight, the long-lived advantage of intensity.
