Description
Technical field
The present invention relates to a kind of architectural waterproof material field, particularly a kind of waterborne thick rubber-plastic waterproof mortar and preparation method thereof belongs to the innovative technology of waterproof paint.
Background technology
At present, waterproof paint along with Transport Facility Constructions such as highway in China, railway, subway, light rails, reach the high speed development of real estate, so its demand rapidly increases as important material of construction.In addition; Along with the national environmental protection rules are more and more stricter; People are increasingly high to the attention rate of environment protection; Also towards the target follow-up of nuisanceless, pollution-free, resource-saving, province's energy, low organic volatile (VOC), progressively replacing oil paint with water-borne coatings from now on is the inexorable trend of coating development in the development of coatings industry.But general aqueous waterproofing paint exists, and function singleness, coating are thin, fine and close, relatively poor to base material sticking power, not shock resistance inadequately, do not resist drawback such as puncture; Usually after finishing waterproof layer; Also need do layer protective layer again, not only prolong the duration, also increase construction costs.Constantly improving the function of aqueous waterproofing paint, improve its quality and state of the art, is all crucial at present and in the future task.Therefore, be necessary to do further improvement and perfect.
Summary of the invention
The object of the invention aims to provide and a kind ofly can partly substitute waterproof roll; One time blade coating can reach the used thickness requirement; Waterborne thick rubber-plastic waterproof mortar of snappiness shock resistance, anti-backfill puncture and preparation method thereof is to overcome weak point of the prior art.
By a kind of waterborne thick rubber-plastic waterproof mortar of this purpose design, it is characterized in that its prescription comprises that following material is by weight: macromolecule emulsion is that 33-65, tackifying resin are that 2.5-6.5, HS fortifying fibre are that 0.3-1.5, waste Crumb rubber are that 20-35, filler are 3-22, auxiliary agent 1.7-5.7 and water 2.5-7.5;
Said macromolecule emulsion is PS-acrylic ester emulsion, and its parts by weight are 38-60, perhaps 45-55, and the main effect of PS-acrylic ester emulsion is the film forming matter of waterborne thick rubber-plastic waterproof mortar.
Said tackifying resin is the water-based rosin milk, and parts by weight are 3-6, perhaps 4-5.Water-based rosin milk and PS-acrylic ester emulsion have good consistency, be prone to be scattered among PS-acrylic ester emulsion, and generation can not flocculate, precipitate; The water-based rosin milk has greatly improved initial bonding strength, has prevented effectively in the construction that incidental slurry drips to hang and fall.There is research to confirm that the water-based rosin milk also has very strong hydrophobicity in coating, impervious waterproof is played effective booster action.
Said HS fortifying fibre is dimension gram polypropylene fibre, and parts by weight are 0.7-1.0, perhaps 0.8-0.9; Dimension gram polypropylene fibre is a kind of high-strength polypropylene pencil monfil; Through surperficial special processing technology; In water-borne coatings, have splendid dispersiveness, it mainly acts on is shock resistance, anti tear and the puncture resistance that improves coating, can also improve tensile strength and resistance to fatigue; And research shows that Vltra tears can be realized the purpose of anti-crack and anti-seepage in concrete and mortar.
Said waste Crumb rubber is the rubber grain that the waste vapour vehicle tyre processes through grinding, and its parts by weight are 25-30, perhaps 27-28; It mainly acts on is superelevation elasticity, heat-insulation and heat-preservation and the noise elimination sound absorption function of giving waterborne thick rubber-plastic waterproof mortar; The more important thing is to make waterborne thick rubber-plastic waterproof mortar have good puncture resistance do not having under the state of resist, can effectively resist the destruction of foreign material such as cullet, iron filings, masonry, pottery.
Said filler is water-ground limestone or talcum powder or softening agent or wilkinite; Parts by weight are 8-17, perhaps 12-13; Said water-ground limestone, talcum powder, softening agent and wilkinite are mainly as the water impermeability and the constructing operation property that improve waterborne thick rubber-plastic waterproof mortar.Wilkinite has thickening power concurrently.
Said auxiliary agent comprises sanitas, water-holding agent, linking agent and/or coupling agent; The parts by weight of sanitas are 0.05-0.25, perhaps 0.1-0.2
Said water-holding agent is a Vltra tears, and parts by weight are 0.1-0.3, perhaps 0.15-2.The water conservation effect that Vltra tears is is excellent, mainly gives the waterborne thick rubber-plastic waterproof mortar homogeneity, makes construction become more quick and easy.
The parts by weight of said linking agent are 0.5-0.9, perhaps 0.7-0.8; Linking agent is a silane coupling agent, and it mainly plays the promotion bonding effect, can improve water-resistant coating and hygrometric state cohesive force, improves tensile strength and tear strength, the anti-aging and weather resistance of enhancement coating; The parts by weight of coupling agent are 0.5-0.8, perhaps 0.6-0.7; Coupling agent is a kind of reactive silane coupling agent that has, and is mainly used in to improve tackifying resin to the avidity between HS fortifying fibre, waste Crumb rubber and the filler.
A kind of making method of waterborne thick rubber-plastic waterproof mortar is characterized in that comprising the steps:
1) cement mortar mixer is scheduled low gear, install a mixing bowl, the adjustment stirring rake is as far as possible near cylinder bottom.
2) when carrying out above-mentioned steps, 33-65 macromolecule emulsion and 2.5-6.5 tackifying resin are added in a mixing bowl, start stirrer, under whipped state, add linking agent, coupling agent, water-holding agent by above-mentioned parts by weight.
3) when carrying out above-mentioned steps, fully stir 10-30 minute after, add softening agent, fortifying fibre and wilkinite by above-mentioned parts by weight.
4) when carrying out above-mentioned steps, continue to stir after 10-30 minute, add water-ground limestone, talcum powder, waste Crumb rubber by above-mentioned parts by weight
5) when carrying out above-mentioned steps, every slurry that will stir casing wall at a distance from shutdown in 10-15 minute shovels in the cylinder with perching knife in the whipping process, avoids stirring inhomogeneous.
6) repeat the 5th step 1-3 time after, add entry by above-mentioned parts by weight and adjust the finished product that waterborne thick rubber-plastic waterproof mortar is the cream pasty state.
The present invention compared with prior art has following unusual effect:
Can partly substitute waterproof roll, one time blade coating can reach the used thickness requirement, has the characteristics of snappiness shock resistance, anti-backfill puncture; Both can be used for the water proof anti-seepage that upstream face also can be used for back side, need not add resist again.The present invention is the multi-occupancy building mortar with heat insulation and heat absorption, noise reduction noise elimination, and a large amount of waste tyre rubber powders that use to the recycling of environment protection and resource, have also been made positive contribution in the prescription.
