According to JG/T 24-2000 " synthetic resin emulsion sand wall shape texture coating " coating that embodiment 1-3 prepares is carried out making sheet and Performance Detection, the result data of its detection sees the following form.
The traditional performance assay
Show that by the data in the table performance of this coating meets the standard-required of JG/T 24-2000 " synthetic resin emulsion sand wall shape texture coating " (W external application type) fully.Can find out also that from the concrete outcome and the data that detect this coating all obviously is better than the technical indicator of standard-required on application property, contamination resistance, cohesive strength, artificial ageing resistance project.Show fully that also this coating system has good satisfying property of standard and suitability.
Compare with protective coating with the construction wall decoration that generally adopts at present, innovative point of the present invention is as follows:
1, the selection of film forming base-material
Film forming base-material of the present invention is selected good pure third polymer emulsion of weather resistant usually for use, wherein pure third polymer emulsion of elasticity can give coating more outstanding tough ability and elasticity, has stronger cracking resistance actual effect, and can improve the integral waterproofing of filming, simultaneously elastic emulsion is filmed and also is present in summer high temperature and uses the deficiency of easily after-tacking and staiing, but can by reasonable second-order transition temperature selection and the later stage crosslinked the improvement.The elastomeric polymer emulsion that this coating selects to have crosslinking feature is the film forming base-material, its second-order transition temperature is-10-0 ℃ between, have the later stage self-crosslinking characteristic.Thereby realize being coated with film elasticity, waterproof, durable, anti-ly after-tack, low laying dust can self-cleaning, high comprehensive integrated effect against corrosion.
2, the selection of nano silicon
The elastomeric polymer microballoon is a kind of micron-sized singularity functional polymer, core-shell type hollow structure for organic and inorganic, have ultralow proportion, the outstanding characteristic of durable stable, outer soft interior hard, easy dispersive, the toughness that is widely used in materials such as coating, pottery, stone material, glass reinforced plastic strengthens, and effectively reduces the higher cost performance of stem body proportion acquisition of material.This microballoon is used for the development of this coating system after coupling processing, can forms remarkable synergistic effect with the film forming base-material, give tough, fine and close, the lightweight of filming, heat insulation special efficacy as nano silicon.
3, the selection of functional stuffing and additive
(1) hollow glass micro-ball
Select the functional filler of the hollow glass micropearl of import, to promote and to guarantee the heat insulating and the reflection effect of whole coating as reflective insulation.Hollow glass micropearl has that low-gravity, thermal conductivity are low, good light heat reflectivity, good, the durable stable good characteristic of intensity, can give film good heat insulating and waterproof effect, also is the key material of present reflective heat-insulation paint.Through experimental verification, the hollow glass micropearl of selecting for use in the sandstone texture coating is also different to some extent in conventional heat insulating coatings, should have big (average 80 orders of particle diameter rank, can provide the texture type to imitate outward), evenly complete, the thermodynamic barrier excellence of suitable wall thickness and intensity, hollow structure, use in the not fundamental characteristics and the requirement of cracky, at present many hollow glass micropearls with import for more suitable with can satisfy, as the hollow glass micropearl product of U.S. 3M, baud company.
(2) heat insulation enhancement additive
Simple hollow glass micropearl is because lightweight, it is difficult to obtain the heat insulating effect of filming of satisfiability usually in effective addition scope, film for the energy-saving heat-insulating type that obtains satisfiability, select for use diatomite and nano-far-infrared additive to carry out composite (mass ratio 1:1) enhancement additive in this system especially as heat insulating function.Wherein diatomite has special cellular structure, well increase-volume and increase volume of voids in system, thus strengthen the heat-blocking action of filming; The nano-far-infrared additive is the nano level dispersion liquid of far infrared ceramic powder, and its infrared emittance can effectively be given the ir radiation of filming certain ability up to 88%.The barrier effect of hollow glass micropearl is worked in coordination with and strengthened to actual effect, and making films obtains the heat insulation effect and the performance of actual effect.
4, the selection of quartz sand
Quartz sand can give the texture coating rough granular sandstone outward appearance as the main stuffing of sandstone texture coating system, and also can play significant enhancing (lifting intensity) effect in the texture coating system.Usually the round shaped grain quartz sand of selecting pure Gao Bai for use adopts 60 orders, 80 orders, 100 orders to carry out grating for best, sets according to the texture texture appearance.
5, the selection of functional agent
The functional agent consumption is the indispensable integral part of coating, film coalescence aid under in this sandstone system, needing equally normally to use, dispersion agent, wetting agent, defoamer, water-holding agent, rheological agent, fungicidal preservative, pH value conditioning agent etc., for reducing the swelling property of coating after by water erosion, in this system, also introduce organic-silicon-modified auxiliary agent, the progressive whole water-intake rate of filming that reduces is beneficial to stronger durable.
6, the selection of rheology enhancer
The sandstone texture coating is scraped or sandblast type system as criticizing of thick-slurry type, must have good base material suitability and batch scraping property requirement, adopt rheology enhancer to carry out rheology modified to system and enhancing in this system with thixotroping structure, make it have good scraping property and the basic viscosity criticized, can be high water conservation adapt to and batch scrape, and the homogeneity and the stability of system status is further promoted.
