Description
Technical field
The present invention relates to the trade sales coating field, be specifically related to a kind of solid gums.
Background technology
Employed glue is different with common glue in the middle of the construction industry, and its requirement has higher adhesive ability, and the time sufficiently long that keeps viscosity.The building glue that uses on the current market has two kinds of modes of production, and a kind of is that manufacturer directly puts on market behind the liquid packaging with chemical materials productions such as Z 150PH, acrylic amides; Packing was put on market after another kind was processed into building glue by manufacturer with high molecular polymer rubber powders such as PVA, EVA, CMC.The packing material that these two kinds of modes of production need is big, energy-conservation inadequately; It is high to put the storing cost on market, economical inadequately; The product of producing uses inconvenient; Toxic substances such as formaldehyde, ammonia, sanitas are arranged, not environmental protection in the glue composition of its production; Product is in transportation, and cracky can cause the wasting of resources; The glue quality is low, synthetic putty poor adhesive force, is prone to the volume skin, comes off etc.; Use the synthetic cement-based material of glue to base materials such as exterior walls, owing to cement based kapillary suction reason is prone to cause expansion, cracking, weathering, problem such as pollute, go mouldy and cause peeling off during freeze-thaw cycle.The feed composition that at present a lot of producers all are directed against building glue has carried out improving and upgrading; Adopt the novel environment friendly building putties rubber powder of raw material production such as latex powder, methylcellulose gum, skimmer, sticker, white cement like Anhui Architectural Sci. Research & Design Inst., it is specifically designed to and replaces building glue configuration inner, external wall putty inferior.But the adhesive for building pigment (solid glue) of prior art, except its adhesive ability power differs, the shortcoming of while ubiquity contaminate environment, the Long contact time that has can cause damage to build labourer's health.
Summary of the invention
The present invention provides a kind of solid gums, adopts light calcium carbonate base material as carrier, by multiple macromolecular material, is aided with multifunctional assistant, and scientific formula forms, and has nontoxic, pollution-free, odorlessness, "dead", the characteristics of not having alkalescence.
In order to achieve the above object, the technical scheme that the present invention adopted is:
A kind of solid gums is made up of following component, and the weight part of each component is:
Lightweight nano-calcium carbonate 50-70
Vltra tears 10-15
Ethylene/vinyl acetate copolymerization rubber powder 4-7
Flyash 5-10
Acrylic amide 10-15
Calcium formiate 1-2
Polycarboxylate high performance water-reducing agent 1-2
Xylogen 1-2
Siloyl group hydrophober 4-6
Vermiculite power 3-5
White titanium pigment 1-3
Nano silicon 3-5.
Said xylogen length is 1mm.
The preparation method: the present invention as carrier, merges the white powder processed with Vltra tears, ethylene/vinyl acetate copolymerization rubber powder, calcium formiate, water reducer, hydrophober, xylogen, SEPIGEL 305, flyash etc. with light calcium carbonate.
After the present invention was water-soluble, its macromolecular material and auxiliary agent depended on light calcium carbonate and form a kind of high performance glue disjunctor.Volume of the present invention is little, accumulating convenient, simple and easy, the environmental protection and energy saving of operation, and it has the following advantages:
1, improves the water-retentivity of putty, prolong the time of coagulation of putty.
2, improve the construction workability of putty, increase the snappiness of putty.
3, improve bleed property, flowability and the redispersible of putty.
4, improve the rupture strength and the wear resistance of putty.
5, improve putty denseness, bonding force and bonding strength.
6, improve putty compactness, reduce the absorption of pore, prevent infiltration, effectively suppress the accumulation of salt in the surface soil of base material water.
7, have high temperature resistant, nontoxic, pollution-free, odorlessness, "dead", the characteristics of not having alkalescence.
Use its coatings formulated, line is not urinated in easy construction, and good leveling property is not rolled up skin, and film forming is fast.
Embodiment
A kind of solid gums is made up of following component, and the weight part of each component is:
Lightweight nano-calcium carbonate 50-70
Vltra tears 10-15
Ethylene/vinyl acetate copolymerization rubber powder 4-7
Flyash 5-10
Acrylic amide 10-15
Calcium formiate 1-2
Polycarboxylate high performance water-reducing agent 1-2
Xylogen 1-2
Siloyl group hydrophober 4-6
Vermiculite power 3-5
White titanium pigment 1-3
Nano silicon 3-5.
Hydrophober is the polymkeric substance of YSR 3286 and organoalkoxysilane.
Said xylogen length is 1mm.
The fluctuation ratio of central envrionment temperature is bigger throughout the year, and winter temperature is lower than-10 ℃, and summer, the body of wall temperature surpassed more than 60 ℃, and the TR that the synthetic putty of glue powder of the present invention adapts to is big, and the principle that can adapt to large-temperature range is following:
1, body of wall very easily absorbs water, and putty will be prone to criticize, and has certain moisture retention; Do not make generation separation bleedings such as putty aggregate, use light calcium carbonate, delayed the hydro-combination process of cement; Make that the cement setting process of setting is slack-off, corresponding the obtaining of the pool time of putty prolongs.
2, use xylogen, acrylic amide etc., strengthen the cracking resistance effect of body of wall.
3, the water reducer in the glue powder makes putty reduce water consumption, improves liquidity enhanced stability.
4, because kapillary suction phenomenon very easily takes place cement-based material, add hydrophober, delay cement Calucium Silicate powder mCaOSiO in the cement hydration process
2NH
2The formation of O prolongs the space lifetime between the cement granules, is convenient to cement-based material and solidifies, and after base material solidified, the absorption that base material significantly reduces water reached the salinity that penetrates into base material through water, suppresses accumulation of salt in the surface soil phenomenon.
5, hardened substrate material structure mainly by cement stone mutually and polymer phase constitute, the bonding interface through inorganic particle and polymer particles intergranular is together.Ethylene/vinyl acetate copolymerization rubber powder, second-order transition temperature is lower, has higher snappiness, can well be glued to cement stone.
6, the median size of flyash is merely 1% of cement median size, infiltrates in the cement plaster, can well be filled among the cement granules hole, makes putty finer and close; Also combine in addition, form stable calcium silicate hydrate, thereby improved the impermeability of putty with free calcium hydroxide.
Respective components adds in the weightless mixing machine successively in will filling a prescription in the production process of the present invention, stirs 10-15min, is mentioned by lift, and through automatic packaging machine metering packing, use then can put goods on the market.
