Abstract
The invention discloses a preparation method of a ground floor plastering gypsum, which is improvement of the ground floor plastering gypsum. The ground floor plastering gypsum is prepared mainly by the following ingredients according to weight percentage: 30-50% of desulfurization building gypsum, 50-70% of fine sand, 0.01-0.04% of binder, 0.015-0.05% of water retaining agent and 0.01-0.05% of retarder. The ground floor plastering gypsum is strong in cohesive force, good in water resistance and low in cost, and does not crack, thus being an ideal choice for replacing traditional plastering materials.
Description
Technical field
The present invention relates to a kind of bottom layer brushing gypsum, belong to material of construction and solid trade waste comprehensive utilization technique field.
Background technology
Brushing gypsum is to be main component with the plaster of Paris, the air hardening cementitious materials that mixes multiple admixture and gather materials and make, it is a kind of novel plastering material, advantages such as it had both had the plaster of Paris high-early-strength, cohesive force is strong, volume stability good, moisture absorption, fire prevention, lightweight, overcome again that the plaster of Paris rate of set is too fast, viscosity is big and shortcoming such as the operation inconvenience of plastering, use more and more widely.Present commercially available bottom layer brushing gypsum adopts plaster of Paris and fine quartz sand and other additive to mix by a certain percentage usually, if fine quartz sand delivery quality instability, very big to the product performance influence, and fine quartz sand price height, cause the product cost height, influence promoting the use of of bottom layer brushing gypsum.
The present invention uses aeolian sand to replace fine quartz sand, and the maximum consumption of aeolian sand can reach 70%, has greatly reduced material cost.Aeolian sand is distributed in China's arid, semiarid zone, and the desert area just accounts for area about 17.85%, so aeolian sand is very abundant as bottom layer brushing gypsum aggregate resource.Because aeolian sand epigranular and stable, silt content is very low, and sorting and psephicity are fabulous, does not need to carry out any processing and just can be used as the use of bottom layer brushing gypsum aggregate, and good with the bottom layer brushing gypsum workability of its preparation, speed of application is fast, stable performance.Can promote the use of in the area that aeolian sand is arranged.
Summary of the invention:
The object of the present invention is to provide a kind of low cost of manufacture, good product performance, stay-in-grade a kind of bottom layer brushing gypsum.
Technical solution: the mass percent component that comprises following material of bottom layer brushing gypsum of the present invention:
Desulphurization building gypsum 30%～48%, aeolian sand 50%～69%, binding agent 0.01%～0.02%, water-holding agent 0.015%～0.03%, animal proteinum glue 0.01%～0.05%.
Desulphurization building gypsum of the present invention is that power-plant flue gas forms desulphurization building gypsum through 160 ℃～190 ℃ hydrothermal treatment consists, described desulphurization building gypsum fineness 200 mesh screen residues 1.8%, presetting period: 7min, final setting time: 14min, folding strength: 4.0MPa, ultimate compression strength: 10.0MPa.
Aeolian sand of the present invention is the fine sand of granularity between 0.05～0.25mm.
Water-holding agent of the present invention is calcium-base bentonite and hydroxypropyl methylcellulose mixtures, described calcium-base bentonite: sucking amount (g/100g) 〉=34, colloid index (ml/15g) 〉=45, expansion multiple (%) is not less than 15, cation exchange capacity (milligramequivalent/100g)＞90, alkalescence coefficient＜1, moisture content (%)＜10, granularity (order) 200.Calcium-base bentonite is main has in the present invention worked in coordination with water retention with Vltra tears, maintenance brushing gypsum unlikely dehydration drying in construction process.
Vltra tears of the present invention is the HPMC7000 Vltra tears.Mainly play water retention, enhancement in the present invention, increase water tolerance and the cohesive strength and the water retaining function of system.
Binding agent of the present invention is water-soluble poval or redispersable latex powder.
Described water-soluble poval is the PVA1788 water-soluble poval, mainly plays enhancement in the present invention, increases water tolerance and the cohesive strength and the water retaining function of system.
Redispersable latex powder of the present invention is vinyl acetate and ethylene copolymer rubber powder.Can replace with water-soluble poval and use, act on identical with water-soluble poval.
Animal proteinum glue of the present invention is the gypsum special retarder, and consumption is few, and retarding effect is good, does not influence the intensity after gypsum hardens.
Bottom layer brushing gypsum of the present invention can prepare by above-mentioned each component is mixed in proportion, and mixes a certain amount of water mixing during use and can use.
Described bottom layer brushing gypsum of the present invention can be applicable to prepare motar, and the method for described application is: the water that bottom layer brushing gypsum is added bottom layer brushing gypsum quality 25～30% stirs, and can carry out wall construction.
Bottom layer brushing gypsum by the present invention's preparation has extremely strong folding strength, ultimate compression strength and cohesive strength, possess alkali resistant, freedom from cracking, shock resistance, performance such as water-fast simultaneously, the while convenient and quick construction, compare with traditional sand-cement slurry technology, shrinkage cracking phenomenon in effectively having suppressed to plaster, common fault such as solved the hollowing that sand-cement slurry, mixed mortar are plastered, ftracture, come off, it is the more novel product that replaces sand-cement slurry, existing cement intensity, again than cement health environment-friendly more, for inner wall decoration provides a kind of better choice.
Compared with prior art, the present invention uses aeolian sand as the bottom layer brushing gypsum aggregate, made full use of good grain composition and the rounding of aeolian sand, and greatly reduced the bottom layer brushing gypsum cost, made its performance stable and good more by optimization to various additives.
