Abstract

The invention relates to acrylic acid modified waterproof mortar comprising cement, quartz sands, pulverized fuel ash, triple superphosphate powder, acrylic acid redispersable rubber powder, a water-repellent agent, a deforming agent and other auxiliary agents. The waterproof mortar with compact structure is obtained by adopting the acrylic acid redispersable rubber powder which has excellent ageing-resistant property and water-resistant property and good quartz sand graduation through formulation design and optimization, not only has good waterproof and impervious property, but also has excellent ageing-resistant property and excellent physical property.

Description

Acrylic acid modified waterproof mortar
Technical field
The present invention relates to a kind of building water-proof mortar material, relate in particular to a kind of polymer modification waterproof mortar for building.
Background technology
Traditional building water-proof material is mostly based on flexible materials, as various waterproof rolls and waterproof paint etc.They form watertight insulation by paving or coating in the building substrate surface.Yet because the compatibility problem of flexible waterproof material and matrix make that its ageing-resistant performance is relatively poor, and cost is higher.Waterproof mortar be a kind of be raw material by cement, sandstone, mix a small amount of admixture and macromolecular material therein,, reduce porosity by adjusting proportioning, increase method such as closely knit performance between each starting material interface, formulated a kind of sand-cement slurry class water-proof material with certain impervious ability.It is bigger that this type of water-proof material can be widely used in structural rigidity, and building deformation is less, and the engineering lower to impervious requirement because this kind water-proof material cost is lower, has good prospects for application.
200910074498.5 1 kinds of environment-friendly type waterproof polymer mortars of patent disclose a kind of waterproof mortar, described waterproof mortar is made up of cement, quartz sand, flyash, plastic of poly vinyl acetate redispersable latex powder, Vinyl Acetate Copolymer tertiary ethylene carbonate redispersable latex powder, water reducer, defoamer, polyacrylic fibre, has good anti-permeability performance and workability.
Existing waterproof polymer mortar, though have good anti-permeability performance, it does not have good aging properties, and its weak point is arranged in actual applications, so its performance remains further perfect.
Summary of the invention
The purpose of this invention is to provide a kind of acrylic acid modified waterproof mortar with premium properties, this mortar has good anti-folding, compressive property, excellent anti-permeability performance and ageing-resistant performance.Waterproof mortar of the present invention consists of:
Cement 42-50
Quartz sand 35-40
Flyash 5-15
Coarse whiting 5-15
Re-dispersible glue powder 2.5-3.5
Ether of cellulose 0.02-0.05
Hydrophober 0.1-0.2
Modification boron-moisten soil 0.2-0.3
Defoamer 0.2-0.3
Water reducer 0.15-0.3
Polypropylene fibre 0.1-0.2
Further, above-mentioned cement is ordinary portland cement, preferred 425 ash concretes.
Above-mentioned quartz sand is preferably two kinds of gratings in 30-50,40-70,50-100, the 70-140 order quartz sand.
Above-mentioned coarse whiting is preferably 200 purpose coarse whitings.
Above-mentioned re-dispersible glue powder is preferably the vinylformic acid rubber powder.
Above-mentioned ether of cellulose is preferably viscosity at the methyl cellulose ether below 10000.
Above-mentioned hydrophober is preferably the hydrophober of organosilicon type.
Above-mentioned defoamer is preferably the modified siloxane defoamer.
Above-mentioned water reducer is preferably carboxylic acid water reducing agent.
It is 6mm that above-mentioned polypropylene fibre is preferably specification.
Acrylic acid modified waterproof mortar of the present invention, with cement is main gelatinous material, adopt the modification of vinylformic acid re-dispersible glue powder, add the quartz sand of different gradation, coarse whiting, hydrophober and the cooperation of other auxiliary agent form, because the vinylformic acid re-dispersible glue powder is compared EVA rubber powder commonly used, excellent in water resistance energy and ageing-resistant performance are arranged, can guarantee that resulting waterproof mortar has good bonding strength and ageing-resistant performance, by optimizing its addition, waterproof mortar solidifies back vinylformic acid rubber powder can form the successive rete therein, cooperate other filler and grating quartz sand, can be so that closely knit waterproof layer has good endurance quality and waterproof impervious characteristic, in addition, owing to adopted high performance cement and good grating quartz sand, can guarantee that by adjusting the prescription composition waterproof mortar of the present invention has excellent anti-folding, physicalies such as resistance to compression.
