Description
Technical field
The present invention relates to construction water proof material field, be specifically related to a kind of bicomponent white Polymer cement materials.
Background technology
Polymer cement materials is for primary structure material with polymer emulsion and cement, interpolation various surfactants stablizes the waterproof paint that filling powder is made through moisture evaporation and hydration reaction, this series products is generally used for the hidden waterproofing work coordinating facing operator guards, such as, for solving roof substrate, waterproof layer, matching between thermal insulation layer and protective layer combines the not high problem of bonding, prevent interlaminar separation and the problem causing heat-insulating property to reduce, denomination of invention is disclose a kind of waterproof polymer mortar in the patent document of " thermal insulation and water proof integrated system of roof covering and constructional method thereof " (Authorization Notice No. is CN101311456B), this mortar has good water resistance, at the northern area of roofing environment relatively dry, the performance of this thermal insulation and water proof integrated system of roof covering waterproof is good, but, in the south that humidity is rainy, when particularly plum rain season arrives, although this thermal insulation and water proof integrated system of roof covering can obtain certain waterproof effect, but owing to being exposed in water for a long time, its waterproof effect and work-ing life will have a greatly reduced quality, and then interlaminar separation can be caused and destroy overall water-repellancy and attractive in appearance.
Summary of the invention
For the defect of prior art, applicant improves system component, by selecting the combination of different polymer emulsion, quartz sand graduation, white cement, under the prerequisite meeting water-proof function requirement, realize toning and the decoration functions of waterproof mortar, simultaneously by adjustment mildew-resistant, algae-resistant material, bicomponent white Polymer cement materials is applicable to soak for a long time the coating moulding at position and decoration.
For achieving the above object, the present invention is achieved through the following technical solutions: this white polymer cement waterproofing mortar is two-component materials, component A is by polymer emulsion, defoamer, solubility promoter forms, B component is by quartz sand, white cement, ether of cellulose, water reducer, the agent of mildew-resistant algae forms, during use, respectively first by component A and B component premix, and then two components are mixed, wherein each constituent mass number is as follows: polymer emulsion 65 ~ 85 parts, defoamer 1 ~ 3 part, solubility promoter 6 ~ 8 parts, quartz sand 60 ~ 65 parts, white cement 40 ~ 60 parts, ether of cellulose 0.02 ~ 0.05 part, water reducer 0.5 ~ 1 part, mildew-resistant algae agent 0.5 ~ 1 part.Above-mentioned composition can meet the technical requirementss such as waterproof, moulding, mildew-resistant, anti-algae simultaneously.
Polymer emulsion available in component A has a variety of, applicant preferably 65 ~ 85 parts polyacrylate dispersion, ethylene-vinyl acetate copolymer emulsion or the mixture of the two, this polymer emulsion is the polymer emulsion of being spent by second-order transition temperature-10.The test-results display low-temperature performance of polyacrylate dispersion, ethylene-vinyl acetate copolymer emulsion or the mixture of the two, water tolerance and weathering resistance are all good.
B component is mainly another important component part of polymer cement waterproof paint: mineral filler, as cement, quartz sand etc.Wherein, cement is the filler that a kind of activity is larger, the most remarkable to the Effect on Mechanical Properties of water-proof coating.White cement is generally high-alumina cement, and the metal-salt of high price is stronger with the active group crosslinked action of polymkeric substance, and better to the modification of polymkeric substance, therefore, applicant selects 40 ~ 60 parts of white cements, and preferred white cement is Heng Shi whiteness more than 87 32.5 white cement.Applicant selects 60 ~ 65 parts of quartz sands, the mixture of the wherein preferred following combination of quartz sand: 20 ~ 40 order quartz sands, 40 ~ 80 order quartz sands, 80 ~ 120 order quartz sands, 200 order silica powders, 600 order silica powders.
As one of the starting material of waterproof paint, the consumption of auxiliary agent is usually little, but effect is very large.It add defect and the paint marketing that not only can avoid producing much coating, the production of waterproof paint and construction process can be made again to be easy to control simultaneously.And the interpolation of some auxiliary agent can give waterproof paint some special functions.Conventional auxiliary agent has water reducer, solubility promoter, defoamer, antimildew disinfectant etc.Wherein, the defoamer preferably waterborne organic silicon emulsion defoamer of 1 ~ 3 part in component A; Solubility promoter preferably 6 ~ 8 parts propylene glycol, ethanol or both mixtures, in B component, water reducer preferably polycarboxylate water-reducer, the naphthalene water reducer of 0.5 ~ 1 part; Ether of cellulose is 20000 viscosity HEMC, the 60000 viscosity HPMC of 0.02 ~ 0.05 part or the mixture of the two preferably; The agent of mildew-resistant algae preferably 0.5 ~ 1 part pyridines, thiazoles, zinc oxide any one or two or more mixture arbitrarily.
The invention also discloses the preparation method of the said products, comprise the steps: first polymer emulsion, defoamer, solubility promoter to be carried out premix in proportion, make component A; By quartz sand, white cement, ether of cellulose, mildew-resistant algae agent premix in proportion, make B component; Before using, A, B component are carried out used in combination according to ratio requirement.
The invention also discloses the using method of described product, in use product be coated in the surface of cement matrix or by pattern, product carried out coating moulding on cement matrix; After products solidifying, firmly waterproof is overall, to reach the requirement of impervious waterproof and coating decoration moulding to form one at substrate surface; Realize opposing external microbe apposition growth simultaneously, keep the long-acting multiple effect attractive in appearance of decoration.
Applicant by being grouped into the one-tenth of bicomponent white Polymer cement materials, proportioning content improves and optimizes, make the cohesive strength of this waterproof mortar, cracking resistance, waterproof, anti-mildew, anti-algae performance significantly improves, in addition, this waterproof mortar also possesses decoration functions, can meet the demand of the cracking resistance at long-term immersion position, waterproof, anti-mildew, anti-algae, coating moulding and decoration.Meanwhile, bicomponent white Polymer cement materials disclosed by the invention is simple with its preparation technology, easy construction, can directly use on wet base, has good market application foreground and economic benefit.
