Abstract
The present invention relates to polymer dry mixed mortar which comprises components in the following mixing proportions by weight: 60% to 65% of quartz sand, 20% to 25% of cement, 8% to 12% of lime stone powder, 3 to 3.5% of starch ether, 1% to 3% of a bentonite thixotropy lubricating agent, 1.5 to 2.0% of organosilicon, 0.15 to 0.20% of a hydrophobing agent, 0.20 to 0.30% of methyl cellulose and 0.30 to 0.60% of cellulose fibers. The present invention does not contain poisonous and harmful substances. The present invention solves the existing polymer mortar problems of inaccurate on-site weighing and inconvenient construction caused by on-site preparation and on-site mixture. The present invention has the characteristics of light weight, high strength, high adhesive force, no seaming, fire retardation, no empty plumping, no cracking, no pulverization, water resistance, high weathering resistance, high water prevention, high air permeability, good impact resistance, good toughness, good workability, and convenient and prompt construction. The present invention is a green environment protecting finishing material without toxic hazard nor pollution.
Description
Technical field
The present invention relates to a kind of building plastering mortar, particularly a kind of polymer mortar.
Background technology
Existing polymer mortar contains poisonous objectionable impurities, is to add acrylate or the aldehydes organic substance mixes by cement, and the crack easily, back of plastering has cohesive force, water-proof breathable properties, shock resistance, toughness, workability, the relatively poor shortcoming of weather resisteant.Existing polymer mortar is respectively starting material to be chosen by unit in charge of construction, the starting material that to pack are respectively opened bag, weigh, are mixed in proportion at the construction field (site), mix forms, because the various uncertain factors in working-yard are more, the workman operates unavoidable appearance metering out of true problem, and influences construction quality.
Summary of the invention
The objective of the invention is to provide a kind of polymer dry mixed mortar, solve existing polymer mortar and contain poisonous objectionable impurities, cohesive force is poor, water-proof breathable properties, shock resistance, toughness, workability, the relatively poor problem of weather resisteant, also solves inaccurate, the on-the-spot allotment of the on-the-spot weighing of existing polymer mortar, mix causes the inconvenient problem of construction.
The technical scheme of the polymer dry mixed mortar of the present invention, its mixing ratio by weight is as follows:
Quartz sand: 60%-65%
Cement 20%-25%
Limestone powder: 8%-12%
Starch ethers 3-3.5%
Wilkinite thixotroping lubricant 1%-3%
Organosilicon 1.5-2.0%
Hydrophobizing agent 0.15-0.20%
Methylcellulose gum 0.20-0.30%
Cellulosic fibre 0.30-0.60%
Above-mentioned hydrophobizing agent is polyvinyl alcohol or calcium stearate.
Above-mentioned polymer dry mixed mortar is the dry powder that is pre-mixed, also packs by norm.
The fineness 0.1-0.5mm of above-mentioned quartz sand.
Fineness＜the 0.1mm of above-mentioned limestone powder.
Beneficial effect: the present invention does not contain poisonous objectionable impurities in material, compare with existing polymer mortar, have that lightweight, high-strength, cohesive force are strong, no seam, fire-retardant, not hollowing, do not chap, not efflorescence, water-fast, weather resisteant is strong, water-proof breathable properties is strong, shock resistance, toughness, good, the characteristics easily of constructing of workability.The reasonable ratio of quartz sand, lime powder and cement in the proportioning of the present invention; Cellulose fiber peacekeeping methylcellulose gum (being called for short mc) plays water conservation, cracking resistance effect, and starch ethers increases cohesive force, and hydrophobizing agent and wilkinite thixotroping lubricant play even water conservation and and easily effect.This proportioning can produce similar skin function behind the thermal insulation layer plastering construction, the water of outside can not penetrate in the thermal insulation layer and go, the steam of thermal insulation layer the inside can come out, and avoids inner steam, aqueous vapor to form hollowing, avoids material generation efflorescence, the crack of outside.Because each material-mix is reasonable in the proportioning of the present invention, drying shrinkage is less, good weatherability, but weather invasion and attack.Be a kind of toxicological harmless, pollution-free, environmental protection finishing material.
The present invention detects through national experiment of building material center, meets DBJ01-63-2002 mortar examination criteria:
| Test item | Assay | |
| Plastering mortar tensile bond strength MPa | The normal temperature normality | 0.88 |
| Water-fast | 0.83 | |
| Freeze-thawing resistant | 0.86 | |
| Heatproof | 0.99 | |
| Test item | Interventions Requested | Assay |
| Plastering mortar | Operable time, h | 2 |
| Snappiness (28d backfin ratio) | 2.5 | |
| The 24h water regain, g/m 3 | 816 | |
| Splitting resistance | Flawless | |
| Water-permeable (24h), ml | 116 |
Be the single component dry powder that is pre-mixed, also packs by norm just when the present invention is dispatched from the factory, do not needed and other material-mix, opened bag at the construction field (site) and can add the water application, accurate measurement, it is very convenient to construct.Be applicable to the wall insulating layer cover, paste styrofoam, the granular polystyrene that bonds, do finish coat mortar etc.
Embodiment
Embodiment: polymer dry mixed mortar of the present invention is the single component dry powder that is pre-mixed, also packs by norm, for example can be packaged into the 25kg/ bag.Powder during construction: water=1: 0.23 (weight ratio)
Weight proportion is as follows:
Component embodiment 1 embodiment 2 embodiment 3 embodiment 4
Quartz sand: 65% 60% 60% 60%
Cement 20% 25% 23% 20%
Limestone powder: 8.85% 8% 9% 12%
Starch ethers 3% 3% 3% 3.5%
Wilkinite thixotroping lubricant 1% 1.25% 2% 2%
Organosilicon 1.5% 2.0% 2% 1.5%
Hydrophobizing agent 0.15% 0.15% 0.2% 0.2%
Methylcellulose gum 0.2% 0.2% 0.3% 0.2%
Cellulosic fibre 0.3% 0.4% 0.5% 0.6%
