Abstract
The invention relates to mortar for high sand rate ethylene sand injection and a preparation method thereof, belonging to the technical field of ethylene sand injection floor. The preparation method comprises the following steps: mixing inorganic powder and an organic film-forming matter according to the mass part of 100:1-10, fully and evenly stirring at a temperature of 5-95 DEG C, and placing for 2-10 hours at room temperature; when the agglomeration phenomenon occurs, grinding and crushing the agglomeration; mixing the mixed powder of the inorganic powder and the organic film-forming matter and oily mater according to the mass part of 100:1-10, fully and evenly stirring at a temperature of 20-90 DEG C, and placing for 2-10 hours at room temperature; grinding and crushing the powder; mixing 16-30 mesh, 30-70 mesh, 70-120 mesh quartz sand according to the mass part of 100:20-100:20-150 to prepare graded sand; and mixing the prepared modified powder and the graded sand according to the mass part of 100:100-300 to obtain the mortar for high sand rate ethylene sand injection. The invention reduces the consumption of epoxy resin, greatly reduces cost, and obviously improves the compressive strength and flexural strength of a sand injection layer.
Description
Technical field
A kind of mortar for high sand rate ethylene sand injection of the present invention and preparation method thereof belongs to and relates to epoxy pressure sandy ground level ground technical field, is specifically related to a kind of method that makes up with modified powder and graded sand to prepare high sand coarse aggregate ratio epoxy mortar and preparation method thereof.
Background technology
Epoxy pressure sandy ground level ground combines the tough and tensile and erosion resistance of Resins, epoxy, and the resistates of quartz sand is rational, high temperature resistant and weather resistance, is a kind of high-performance terrace.Have very high physicals and stronger chemical property.It is the solvent-free epoxy resin system owing to what adopt that epoxy is pressed the sandy ground level ground, pollution-free in construction process, odorlessness after solidify on ground, and bacteria growing inhibiting has the incomparable advantage of other industry ground slabs.Anti-heavy duty, anti-skidding place: garage, storage, mould and machinofacture workshop.Can be applied to a lot of industry and commercial occasion, all require the lasting zone of wear resistance such as food and beverage industries, accurate industry, medication chemistry, electronics manufacturing, clean room, laboratory and research institution, water treatment and disposal site, metal processing and refinery, fiber production and textile mills, papermaking and pulp mill etc.
But present epoxy is pressed sand technique, because the quartz sand space in the mortar is more, need more Resins, epoxy just can fill up these spaces, therefore needed amount of epoxy is very large, because space therebetween is more, the ultimate compression strength of epoxy mortar layer and folding strength are also not high enough simultaneously.
Summary of the invention
The object of the invention is to avoid weak point of the prior art, the problem for above-mentioned prior art exists provides a kind of mortar for high sand rate ethylene sand injection and preparation method thereof.
A kind of mortar for high sand rate ethylene sand injection of the present invention, comprise below by the mass fraction proportioning,
Inorganic powder 100,
Organic binder matter 1-10,
Oily matter 1-10,
16-30 order quartz sand 100,
30-70 order quartz sand 20-100,
70-120 order quartz sand 20-150,
Described inorganic powder can be one or more the mixture in silica powder, Paris white, zinc sulfide white, talcum powder, mica powder or the wilkinite;
Described organic binder matter can be resin: the mixture of one or more in vinyl acetate resin, vinyl chloride resin, butylated resin, Resins, epoxy, urethane resin, the unsaturated polyester resin;
Described oily matter can be one or more the mixture in white mineral oil, Albolene, oleic acid, linolic acid, dibutyl phthalate, dioctyl phthalate (DOP), glycerine, the vegetables oil.
The preparation method of a kind of mortar for high sand rate ethylene sand injection of the present invention, step is as follows:
(1) with inorganic powder and organic binder matter by 100: the mass fraction of 1-10 mixes, and stirs under 5-95 ℃, and at room temperature places 2-10 hour; When clustering phenomena is arranged, it is ground;
(2) with the mixed powder of inorganic powder and organic binder matter and oily matter by 100: the mass fraction of 1-10 mixes, under 20-90 ℃, stir, and in the chamber mixed lower the placement 2-10 hour; The gained powder grinds processing;
(3) with 16-30 order, 30-70 order, 70-120 order quartz sand by 100: the mass fraction of 20-100: 20-150 mixes and makes graded sand;
(4) graded sand that the modification powder that step (2) is made and step (3) make is by 100: the mass fraction of 100-300 mixes, and obtains mortar for high sand rate ethylene sand injection.
Described inorganic powder can be one or more the mixture in silica powder, Paris white, zinc sulfide white, talcum powder, mica powder or the wilkinite;
Described organic binder matter can be resin: the mixture of one or more in vinyl acetate resin, vinyl chloride resin, butylated resin, Resins, epoxy, urethane resin, the unsaturated polyester resin;
Described oily matter can be one or more the mixture in white mineral oil, Albolene, oleic acid, linolic acid, dibutyl phthalate, dioctyl phthalate (DOP), glycerine, the vegetables oil.
The present invention at first carries out grating to quartz sand, and then introduces the inorganic powder through modification.After inorganic powder coated through filmogen, oil absorbency reduced greatly, use again the oily matter modification after, have certain adhesive, the last and compound mortar that makes of graded sand.This mortar is inner because powder packed is arranged, voidage reduces, simultaneously, the powder of modification is low to the Resins, epoxy specific absorption, have the powder that the surface has an adhesive and under the effect of trowelling machine, more enrichment can be arranged on the screed surface, thereby form and press closely layer of sand and more closely knit pressure sand upper layer, in next step grouting process, reduced the absorbed dose to Resins, epoxy.The sand glue mass ratio of mortar for high sand rate ethylene sand injection is 12-15: 1, with respect to the pressure sand of tradition skill, greatly saved content of epoxy resin, and reduced largely pressure sand cost.
The present invention has following features:
(1) quartz sand and modified inorganic powder process science grating, thus maximum packing density had.
(2) inorganic powder has reduced oil absorbency through twice-modified, can sedimentation in mortar, enrichment to a certain degree can be arranged on the mortar surface under the effect of trowelling machine.
(3) do not change existing pressure sand technique, but sand glue has reduced the consumption of Resins, epoxy than greatly improving, and greatly reduces cost.
(4) owing to reduced mortar voids, press ultimate compression strength and the folding strength of layer of sand to be significantly improved.
