Description
[technical field]
The present invention relates to paint field, be specifically related to that a kind of snappiness is splendid, shock resistance, waterproof and breathable, the flexible texture coating having good sound-absorbing effect and preparation method thereof.
[background technology]
Texture coating originates from the beginning of the '20s in last century, and world structure at that time is just transferring to from war greatly develops science and technology, and various countries are also to improve people's living standard for fundamental state policy, and construction industry is also like this.Various new construction style occurs thereupon in a large number; Stucco (plaster) occurs at the north America region in this period, and it was the architectural style coming from Mediterranean Sea formula originally, a large amount of substitute adopting natural silt particle and stone material to do decoration of exterior wall and occur.
At that time due to a large amount of appearance of cement products, someone had found out the way utilizing cement and sand to add toner, to replace those expensive original timbers.But its effect extraordinary image Europe cob wall smeared of rural silt, therefore named " colored cement mortar ", has another name called Stucco, and comes into vogue.Less demanding to quality of that age, the coating for mortar type requires neither be very strict; But As time goes on, its shortcoming also more and more not accept by people, therefore decorative plaster is not used gradually.Until the seventies, the problem of environmental protection is paid attention to by people gradually, and Stucco is employed again, but cement has become ameliorative cement, which greatly enhances its superiority.Enter the eighties, the requirement of people to product is more and more higher, and cement characteristic easy to crack cannot solve all the time.At this moment the sand wall slurry coating material using synthetic emulsion as binding agent arises, and it is not only attractive in appearance charm, and has good protectiveness, and other performance of product also improves greatly.After the nineties, the application of the sandy paint of pulpous state is very universal, particularly North America market, and in exterior coating, the share of market of pulpous state texture coating is more than 50%.
In the middle and later periods nineties, outer wall building coating starts progressively to rise, and comprises the true mineral varnish belonging to sandy paint, also comes into vogue at this moment.But due to the restriction of overall trade management level and construction at that time, all there is fading and the problem, problem of Cracking most serious of all such as peeling off in various degree in early stage flat paint and true mineral varnish.Flat paint cannot be controlled effectively in construction process due to construction thickness, cannot solve the problem of wall crazing at all.Until the end of the nineties, after housing industry formally becomes national leading industry, domestic active demand one effectively can prevent wall crazing, and abundant expression forms, environment friendly and pollution-free wall body decoration product; Meanwhile, in order to standard market, build the Ministry of worker and revised " synthetic resin emulsion sandy paint " in spy in 2000, and formally implement on December 1st, 2000.
For water-based elastic paint, most research staff only rests in the screening study aspect to elastic aqueous emulsion, namely elasticity performance test (as: unit elongation, cohesive strength, anti-stain characteristic can etc. or carry out orthogonal test to one species different manufacturers emulsion) is carried out to the kind (organosilicon crylic acid latex, pure-acrylic emulsion, benzene emulsion) of elastic aqueous emulsion, filter out better elastic aqueous emulsion, and the research of other material in coating is thinked little of or is placed on back burner.Flexible texture coating, as one of water-based elastic paint important branch, has the general character of general elastic coating, also has the aspect that it is special.
Common characteristic is texture coating and general elastic coating is all adopt water, elastic emulsion particle, color stuffing and other aqueous promoter Homogeneous phase mixing to form, on coating after wall along with the moisture evaporation in coating, together with elastic emulsion particulate and color stuffing particle are slowly tightly packed.Along with the moisture evaporation of coating is complete, elastic emulsion particulate is attracted each other and fusion together, is got up by color stuffing particle encapsulation, forms continuous print paint film.Texture coating and elastic coating all have identical membrane formation mechanism.
Texture coating has difference with common elastic coating again, and the color stuffing proportion in flexible texture coating is very large, and the color stuffing proportion of most texture coating is 60% or more.The ratio that in part texture coating formula, color stuffing accounts for coating weighs 70%.Shared by general elastic coating color stuffing, the proportion of coating is generally 20-30%, at most also can not more than 40%.Therefore in texture coating, the reasonably combined elasticity effect to showing after coating film forming of color stuffing is very large.
Secondly, texture coating, with the collocation of the individual character of its with countless changes three-dimensional texture, more options, represents unique spatial view, enriches and vividly, makes us fresh and new.And meet Integral decoration style with individual character creation, make texture coating in decoration, show the individual style of oneself! This Novel artistic coating, has brought the smooth type epoch of wall body coating into the new era of the concavo-convex coating of natural environmental-protective type.In order to create three-dimensional texture, the filler that in texture coating, a large amount of use particle is larger.Texture coating and the difference of general elastic coating are just that texture coating filler large or fine granule is seriously unbalanced.Therefore texture coating shows the collocation that good elasticity must take into full account thickness filler after being thought of as film; mutually pile up formation by thickness filler in filler to arrange more closely; along with the moisture evaporation of coating is complete; elastic emulsion particulate is attracted each other and fusion together; color stuffing particle encapsulation is got up, forms continuous print, resilient paint film.Rational thickness filler can form closely consistent arrangement, paint film can the masterpiece used time can not because of occurring the filler disappearance of local or because of there is space between thickness, continuous print paint film being produced to the defect of local outside, uneven paint film outside stress time cause part paint film first to break, have a strong impact on the attractive in appearance of coating and the various function of coating self.The paint film that tight filler is formed has equilibrium elasticity evenly can be resisted external force and cover fine cracks.
In sum, how keep when color stuffing is high there is good elasticity and resistance to settling is the direction that research staff makes great efforts.
Texture coating is in order to create three-dimensional texture, and comparatively ideal constructional method is scraped for criticizing, and then utilizes various instrument to create the moulding of various uniqueness.Consider that constructional method is artificial batch and scrapes, therefore texture coating needs mud viscosity, workability and good open hour.The denseness of texture coating should control in construction zone of reasonableness, and the viscosity of texture coating can not be too high and have influence on workability.But the color stuffing proportion in texture coating is very large, and the color stuffing proportion of most of texture coating is 70%-80%.And texture coating filler large or fine granule is seriously unbalanced.Secondly in texture coating, the filler of the particle that particle diameter is large is more, and the self gravitation of individual particle is large.Large and the particle self gravitation of color stuffing proportion cause texture coating easily to occur in storage color stuffing sinks, the phenomenon of oily water separation.
Above-mentioned all situations illustrate that the stability of texture coating exists a lot of uncertain factor, make heavy color stuffing stable and uniform in texture coating be distributed in coating to be the problem of a solution to be studied under how enabling texture coating have rational denseness.

Performance Detection
Detection method is with reference to GB/T17671 " Test method for strength of hydraulic cement mortar " and GBT1748 " putty membrane snappiness assay method ").
1. cohesive strength and snappiness are given prominence to
The latex particle that elasticity in texture coating is mainly water-based provided, the present invention selects the non-resilient emulsion of organic-silicon-modified pure acrylic acid and elastic pure acrylic latex to carry out composite, the non-resilient emulsion of organosilicon-modified acrylic mainly provides the tensile strength in paint film, because elastic emulsion is because second-order transition temperature is lower, the paint film formed in normal temperature situation is soft and have viscosity, and the cohesive strength of paint film is poor.The non-resilient emulsion of organic-silicon-modified pure acrylic acid and elastic pure acrylic latex carry out composite, the tensile strength that organosilicon-acrylic resin emulsion provides and elastic pure acrylic latex provide excellent unit elongation to combine, and make paint film have balanced cohesive strength and snappiness.
Sepiolite cashmere is a kind of rich-magnesium clay mineral of chain-like structure, in compact mass, threadiness.After processing of bursting at the seams, sepiolite cashmere is become by sepiolite raw ore.After deliberation, staple length is only had to be that the sepiolite cashmere of 0.2-0.5mm is just suitable for body series.Sepiolite cashmere sense of touch is smooth, quality is light, plasticity-is strong, also there is larger specific surface area, shrinking percentage is low, not easy to crack and there is satin luster simultaneously, in flexible texture coating, sepiolite cashmere provides satin luster for coating and utilizes the long bridging effect bearing part of suede, thus improves the snappiness of coating further.
2. good impact resistance
Proportion in texture coating shared by filler is far longer than the ratio in latex particle, and therefore in flexible texture coating, filler composite is also play a crucial factor to the snappiness of texture coating and shock resistance.
The present invention's employing is stone grain is natural siliceous sand, the size calcite that before disdaining, texture coating is conventional and Snow Flower White building stones.Quartz sand is a kind of silicate minerals of hard, wear-resisting, stable chemical performance, and its main mineral constituent is SiO
2, the color of quartz sand is oyster white or semi-transparent clear shape, hardness 7.And common building stones structure is more loose, hardness is only 2-3, and oil number is also bigger than normal, so at identical water-based emulsion content with in the texture coating of the filler of identical grating, uses the texture coating of natural siliceous sand to show more outstanding in elasticity and shock resistance.Simultaneously, the silicon powder with larger specific surface area is used in (specific surface area of SILICA FUME reaches 20000 ㎡/kg) in flexible texture coating, can the space of filler aggregate and filler well, make thick slurry more closely knit, to reach the object improving shock resistance.In addition because its specific surface area is large and coating is tight, also effectively reduce moisture content to the infiltration of coating, improve the water tolerance of coating.
3. the resistance to settling of excellence and the open hour
The STOL content coating that texture coating is made up of the sand material of different-grain diameter and proportion, sand content generally reaches more than 60%, and sedimentation is the universal phenomenon of sandy paint.The present invention adopt neusilin be the good saponite of colloidal property, smectites through the natural two-dimensional nano-powder material of deep processing, sixteen trihedrons of base uniqueness and trioctahedron mixed structure can give the suspension of system excellence, anti-settling property, thixotropy and thickening power.Effectively arrange in pairs or groups with Mierocrystalline cellulose and alkali swollen thickener, both the deficiency that long chain-like molecular structure class organic thickening agent thixotroping ability is low had been made up, thickening is carried out to coating system simultaneously, make product system play mutually collaborative network structure effect, ensure texture coating not stratified, the not sedimentation within the maintenance phase under STOL content prerequisite; Verify by experiment, above thickening combination can provide rubble grain balance support power effectively, effectively prevent the phenomenon that building stones sedimentation occurs coating within storage period, also efficiently solve the grain effect of texture coating artistic design, the contradiction between fixed effect and application property.Neusilin is in the use of flexible texture coating system simultaneously, greatly improves the open hour of system, makes construction that time enough can be had to carry out effect moulding and finishing.
