Abstract
The invention discloses a preparation method of composite mortar. The preparation method comprises following steps: (1) preparing raw materials, which comprises following components in percentage by volume: 40 to 50% of sawdust or waste straw, 15% to 25% of stone powder, and 10% to 20% of tailing sand, the balance being silicate cement and bentonite; (2) adding 0.6 ton of water into a container, heating the water to the temperature of 100 DEG C with boiler steam, then slowly adding 25 kilograms of polyvinyl alcohol into the boiling water so as to obtain thick glue; (3) adding 0.3 ton of water into the thick glue obtained in the step (2), evenly mixing so as to obtain glue; (4) pouring the raw materials mentioned in the step (1) into a blending tank, evenly mixing, and then adding the glue obtained in the step (3) so as to obtain the composite mortar. The preparation method fully utilizes the waste, not only ensures the binding strength of the mortar, but also greatly reduces the production cost, and has positive effects on reutilization of resource and environmental protection.
Description
Technical field
The present invention relates to the construction material field, specifically a kind of preparation method of composite mortar.
Background technology
Mortar, as a kind of common emplastic in building operation, by a certain proportion of sand and consolidating material (cement, lime putty, clay etc.) Jia Shui with become.Commonly used have sand-cement slurry, mixed mortar, lime mortar and a 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 class mortar adopted is plant produced, energy consumption is high, and cost is higher, and product, than great, must first get rid of slurry and mortar could be spread on the light face, especially for ceiling, and more difficult construction, but also obscission easily appears, cause work consuming, consuming time.
Summary of the invention
The invention provides a kind of preparation method of composite mortar, solved mortar in the past and be 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 the per-cent meter 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 ℃, then the polyvinyl alcohol of 25 ㎏ is slowly added in boiling water, 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) after adding agitated pool to mix the described raw material of step (1), add the glue generated in step (3), and constantly stir, obtain thus composite mortar.
Described step (1) Raw by volume per-cent meter consists of: sawdust or useless stalk 45% ~ 50%, and stone flour 20% ~ 25%, tailings 15% ~ 20%, all the other are silicate cement and wilkinite.
Described step (1) Raw by volume per-cent meter consists of: sawdust or useless stalk 45%, and stone flour 20%, tailings 15%, all the other are silicate cement and wilkinite.
Described step (1) Raw by volume per-cent meter 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.
In described step (2), the 25kg polyvinyl alcohol is all added consuming time in boiling water to be 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 after available useless stalk processing, replace, said useless stalk processing here mainly refers to stalk is processed into and meets the stalk end that granular size requires, and the remaining waste stone dust of sandstone factory and tailings are worked as filler, silicate cement can be any common silicate cement, as the 425# silicate cement.
Glue in the present invention is different from 801 glue on the market, 801 glue on the market be by polyvinyl alcohol and formaldehyde in acidic medium through polycondensation, then make after amination, contain unreacted formaldehyde in preparation process, hazardness is larger.And glue of the present invention is by adding polyvinyl alcohol in the boiling water at 100 ℃, the dense glue of colloid dissolving generation is obtained, whole process will keep the condition of high temperature always, do not relate to formaldehyde, hydrochloric acid etc. in preparation process, do not generate other objectionable impurities yet, the material that belongs to environmental type, therefore being safe from harm property substantially.
The present invention, in preparing the glue process, adds the operating time of polyvinyl alcohol that certain being particular about arranged, and all may cause the poor performance of glue too soon or too slowly, directly affects the quality of composite mortar.Through a large amount of experiment showed,, the polyvinyl alcohol of 25kg is added in 0.6 ton of boiling water fully, approximately need 5 minutes, the glue performance now obtained is best.
Composite mortar prepared by the present invention, the difference of temperature during according to construction, the proportioning of adjustment product, generally be adjusted to mortar and do not flow pendant, 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 has replaced traditional raw material coarse sand with sawdust, and simultaneously, what most of raw material adopted is waste material, as sawdust, stone flour, tailings, so not only accomplish taking full advantage of of refuse, recycling and the environmental protection of resource have all been played to positive effect, more greatly reduced production cost.
2, the glue that the present invention generates in the situation that guaranteed its cohesive action, does not contain the objectionable impuritiess such as formaldehyde, and more environmental protection of the composite mortar that makes the present invention obtain is less to people's hazardness.
3, the present invention can realize stirring at the construction field (site), and the direct production composite mortar, bring great convenience to engineering construction especially suburb engineering construction.
