The invention discloses a natural anhydrous gypsum-made bonding material. The natural anhydrous gypsum-made bonding material comprises: by mass, 75 to 85 parts of natural anhydrous gypsum powder, 5 to 15 parts of an alkaline excitant, 5 to 10 parts of fly ash, 0.5 to 1.0 part of acidic excitants, 0.05 to 0.2 parts of one or more water-retaining agents and 0.50 to 1.0 part of rubber powder. The natural anhydrous gypsum-made bonding material has good stability, good water retention, good liquidity, strong adhesiveness, good affinity and good interface activity, can greatly improve adhesion between a product and a base material, has functions of resisting shrinkage and mildewing, avoids utilization of gauze at a joint, realizes firm bonding, has micro-dilatancy properties and prevents cracking.
Description
One, technical field
The present invention relates to a kind of matrix material for building, specifically a kind of natural anhydrous gypsum-made bonding material.Matrix material of the present invention is mainly used in the stickup of exterior-wall heat insulation styrofoam, extruded sheet, decorated gypsum board and ceramic tile, also can be used for the building by laying bricks or stones of gypsum substrate, piece or other light wall material, bonding, squeegee etc.
Two, background technology
In recent years, the common report of exploitation of the gypsum caking agent of various base materials is developed as the master but mainly concentrate on take semi-hydrated gypsum, plaster of Paris etc. as base material, and it is abundant to there is no human China reserves, the natural dehydrated gyp-exploitation adhesives that grade is good.The production of semi-hydrated gypsum exists large, the with serious pollution problem of energy consumption, and the semi-hydrated gypsum water tolerance is relatively poor, need not calcining, energy-conserving and environment-protective and do adhesives with natural anhydrite, and water tolerance is better than semi-hydrated gypsum, so the importance of more aobvious its exploitation.
Three, summary of the invention
The present invention aims to provide a kind of water tolerance height, low, the simple natural anhydrous gypsum-made bonding material of technique of cost.Technical problem to be solved is to prepare matrix material take dehydrated gyp-as base-material.
Technical solution problem of the present invention adopts following technical scheme:
The characteristics of natural anhydrous gypsum-made bonding material of the present invention are that its raw material is constructed as follows by mass fraction:
Natural anhydrous plaster powder 75-85 part, alkali-activator 5-15 part, flyash 5-10 part, acidic activator 0.5-1.0 part, water-holding agent 0.05-0.2 part, rubber powder 0.50-1.0 part.
The characteristics of natural anhydrous gypsum-made bonding material of the present invention also are: the granularity of described natural anhydrous plaster powder is not less than 200 orders, and specific surface area is 4000-5000cm
2/ g.
The characteristics of natural anhydrous gypsum-made bonding material of the present invention also are: described alkali-activator is cement, and strength grade is 42.5
#More than.
The characteristics of natural anhydrous gypsum-made bonding material of the present invention also are: described acidic activator is one or more in sylvite series exciting agent, sodium salt series exciting agent, the metal sulfate exciting agent, if when several, ratio is any.
The characteristics of natural anhydrous gypsum-made bonding material of the present invention also are: described acidic activator is vitriolate of tartar and Tai-Ace S 150, and mass ratio is 3: 2.
The characteristics of natural anhydrous gypsum-made bonding material of the present invention also are: described water-holding agent is one or more in methylcellulose gum, Vltra tears (HPMC), the hydroxyethylmethyl-cellulose (HEMC), if when several, ratio is any.
The characteristics of natural anhydrous gypsum-made bonding material of the present invention also are: described water-holding agent is Vltra tears.
The characteristics of natural anhydrous gypsum-made bonding material of the present invention also are: described rubber powder digests the Re5010 rubber powder of learning group's production for German watt.
The preparation method of matrix material of the present invention operates according to the following steps:
Natural anhydrite utilization industry ball mill grinding is obtained natural anhydrous plaster powder, and fineness is not less than 200 orders, and specific surface area is at 4000-5000cm
2/ g; Each raw material mixed and stir according to proportional quantity get product.
During use according to water cement ratio 0.30-0.40: 1 ratio is mixed the natural anhydrous gypsum-made bonding material of water and the present invention preparation and is stirred and can use.
Matrix material of the present invention is take natural inorganic gelling material-anhydrite as base-material, is dry mixed with admixture and flyash etc. that the building that forms is built by laying bricks or stones and filled, adhesives.Only need during use in accordance with regulations water cement ratio scope add water mix mix after, the back side that directly is put on styrofoam, extruded sheet, decorated gypsum board and ceramic tile gets final product, adhesives bonding strength with the natural anhydrite preparation is high, and saving of work and time is desirable green building material.Anhydrite is a kind of sulfate mineral, and its composition is anhydrous calciumsulphate, is that with the difference of gypsum it does not contain crystal water, so claim again dehydrated gyp-.Natural dehydrated gyp-has potential hydration activity, need not calcine, and under certain admixture excitation, its product has hardening strength height, water-tolerant, time of coagulation is suitable, bonding strength is high characteristics.Because natural dehydrated gyp-need not calcined, only need grinding, mixing, compare semi-hydrated gypsum base and plaster of Paris, save energy, minimizing are polluted, and adding coal ash, thereby reduce production costs, and improve the market competitiveness.Especially for natural dehydrated gyp-, it is good to have an adhesiveproperties, the more high feature performance benefit of intensity, so this product will occupy an important position in gypsum base adhesives series product.
The time of coagulation of indirect material of the present invention is moderate, and bonding strength has satisfactory stability, water-retentivity greater than 0.6MPa to building by laying bricks or stones of gypsum substrate, aerated-block or other light wall material; Adhesiveproperties is strong, have the performances such as good avidity, good oilness, anti-contracility and anti-mildew change, need to not use gauze at seam crossing, and is bonding firm, has micro-expansibility, stopped cracking phenomena.
