The invention discloses a kind of preparation method of composite mortar, comprise the steps: (1) raw material by volume percentages consist of: sawdust or useless stalk 40% ~ 50%, stone flour 15% ~ 25%, tailings 10% ~ 20%, all the other are silicate cement and wilkinite; (2) 0.6 ton of water is injected in a container, by Boiler Steam, water is heated to 100 DEG C, then the polyvinyl alcohol of 25kg is slowly added in boiling water, generate dense glue; (3) add 0.3 ton of water in the dense glue generated to step (2), after stirring, generate glue; (4) raw material described in step (1) is added after agitated pool mixes, add the glue generated in step (3), obtain composite mortar thus.The present invention has accomplished making full use of of refuse, on the basis of cohesive strength that ensure that mortar, greatly reduces production cost, all serves positive effect to the recycling of resource and environmental protection.
Description
Technical field
The present invention relates to construction material field, specifically a kind of preparation method of composite mortar.
Background technology
Mortar, as the common emplastic of the one in building operation, is added water into by a certain proportion of sand and consolidating material (cement, lime putty, clay etc.).Conventional has sand-cement slurry, mixed mortar, lime mortar and clay mortar.
At present, reasonable mortar has dry-mixed mortar and anticracking grout, and main preparation methods is first the oven dry of river sand, adds that renewable dispersed latex powder, ordinary Portland cement, ether of cellulose etc. are as binding agent, adds anti-crack fiber etc. as cracking-resistant material.But what this kind of mortar adopted is plant produced, and energy consumption is high, and cost is higher, and product is than great, and light face must first be got rid of slurry could spread mortar, especially for ceiling, more difficult construction, but also easily occur obscission, causes work consuming, consuming time.
Summary of the invention
The invention provides a kind of preparation method of composite mortar, the mortar solved in the past is unfavorable for that suburb engineering construction, production cost are higher, also easily occur coming off simultaneously, affect construction quality, work consuming, problem consuming time,
The present invention solves the problems of the technologies described above adopted technical scheme: a kind of preparation method of composite mortar, is characterized in that: comprise the steps:
(1) raw material by volume percentages consist of: sawdust or useless stalk 40% ~ 50%, stone flour 15% ~ 25%, tailings 10% ~ 20%, all the other are silicate cement and wilkinite;
(2) injected in a container by 0.6 ton of water, by Boiler Steam, water is heated to 100 DEG C, more slowly added in boiling water by the polyvinyl alcohol of 25 ㎏, and stir constantly, after two hours, colloid is dissolved, and generates dense glue;
(3) add 0.3 ton of water in the dense glue generated to step (2), after stirring, generate glue;
(4) raw material described in step (1) is added after agitated pool mixes, add the glue generated in step (3), and constantly stir, obtain composite mortar thus.
Described step (1) Raw by volume percentages consists of: sawdust or useless stalk 45% ~ 50%, stone flour 20% ~ 25%, tailings 15% ~ 20%, and all the other are silicate cement and wilkinite.
Described step (1) Raw by volume percentages consists of: sawdust or useless stalk 45%, stone flour 20%, tailings 15%, and all the other are silicate cement and wilkinite.
Described step (1) Raw by volume percentages consists of: sawdust or useless stalk 45%, stone flour 20%, tailings 15%, silicate cement 18% and wilkinite 2%.
The particle length of described sawdust or useless stalk is 0.1cm-0.6cm.
All to be added by 25kg polyvinyl alcohol in boiling water in described step (2) consuming time is about 5 minutes.
Raw material major part of the present invention is waste material, such as sawdust, stone flour, tailings, sawdust replaces traditional coarse sand, when sawdust is not enough, also can replace with after useless stalk processing, useless stalk processing mentioned here mainly refers to the stalk end of being processed into by stalk and meeting granular size and requiring, the remaining waste stone dust of sandstone factory and tailings then work as filler, silicate cement can be silicate cement common arbitrarily, as 425# silicate cement.
Glue in the present invention is different from 801 glue on the market, 801 glue be on the market by polyvinyl alcohol and formaldehyde in acidic medium through polycondensation, more obtained after amination, containing unreacted formaldehyde in preparation process, hazardness is larger.And glue of the present invention is by adding polyvinyl alcohol in the boiling water of 100 DEG C, the dense glue of colloid dissolving generation is obtained, whole process will keep the condition of high temperature always, formaldehyde, hydrochloric acid etc. is not related in preparation process, other objectionable impurities is not generated yet, belong to the material of environmental type, therefore being safe from harm property substantially.
The present invention is being prepared in glue process, and there be certain being particular about the operating time adding polyvinyl alcohol, and too soon or all may cause the poor performance of glue too slowly, directly affects the quality of composite mortar.Prove through a large amount of experiments, added by the polyvinyl alcohol of 25kg in 0.6 ton of boiling water completely, approximately need 5 minutes, the glue performance now obtained is best.
Composite mortar prepared by the present invention, according to the difference of temperature during construction, the proportioning of adjustment product, is generally adjusted to and does not flow pendant with mortar, easily construct and be as the criterion.
To sum up, the present invention compared with prior art has the following advantages and beneficial effect:
1, the present invention's sawdust instead of traditional raw material coarse sand, and meanwhile, what most of raw material adopted is waste material, as sawdust, stone flour, tailings, so not only accomplish making full use of of refuse, positive effect has all been served to the recycling of resource and environmental protection, more greatly reduces production cost.
2, the glue of the present invention's generation is when the cohesive action that ensure that it, not containing objectionable impuritiess such as formaldehyde, and the composite mortar that the present invention is obtained more environmental protection, less to the hazardness of people.
3, the present invention can realize stirring at the construction field (site), and direct production composite mortar, brings great convenience to engineering construction especially suburb engineering construction.
