Abstract
The invention relates to gypsum-based door and window seam filling and sealing mortar as well as a preparation method and an application thereof. The gypsum-based door and window seam filling and sealing mortar is prepared from the following components in parts by weight: 100 parts of waste gypsum, 20-200 parts of active admixture, 0.01-10 parts of water reducing agent, 0.1-50 parts of excitant, 0-10 parts of thickening time control agent, 0-30 parts of binding agent, 0-10 parts of air entraining agent, 0.01-30 parts of plastic retaining agent, 0.01-10 parts of water repellent, 0-5 parts of starch ether, 0-150 parts of powder filler and 0-300 parts of aggregate. Compared with the prior art, the mortar has the advantages of simpleness and convenience in construction, good filling capability, high adhesion capability, good durability, low cost and the like; as the mortar takes chemical gypsum such as desulfurization gypsum and phosphogypsum as main binding materials, a novel application is provided for resource utilization of waste gypsum, not only is material property improved, but also the cost is lowered, and the purposes of sewage treatment and emission reduction are achieved.
Description
Technical field
The invention belongs to material of construction and technical field of building construction, especially relate to a kind of gypsum base door and window joint filling seal sand slurry and its preparation method and application
Background technology
Residential housing leakage of door & window water problems is comparatively general phenomenon always for a long time, and this is also one of the strongest problem of residential customer reflection.Thisly because seepage causes big area metope, peeling off appears in house wall surface, finally causes house moist and make room musty dense, has not only damaged indoor decoration, also directly has influence on the physical and mental health of resident family.Moreover, for repairing leakage of building chamber, people's business that people spend for this reason and material resources and financial resources are quite huge, are upsetting people's work, life, affect the work-ing life of whole building buildings.
Joint filling sealing material is selected and the quality of quality is one of main reason affecting door and window construction quality.Pointing the most frequently used in erection of doors and windows is sand-cement slurry, polyurethane foam etc., and because conventional cement mortar cohesive force is poor, deformability is poor, and easily shrinkage cracking, is easy to occur Seepage.Polyurethane foam seal gum cementability is good, joint filling speed of application is very fast, good springiness also, there is good Restoration, can be suitable for dynamic seam, but polyurethane sealant also has some shortcomings, as wayward in construction quality, whipping agent is filled eakiness and is easily caused and leak, the water resistance of material own is poor, particularly alkaline-resisting water, resistance toheat are poor, single component glue package stability packed and ectocine larger, conventionally solidify slowlyer, under high thermal environment, may produce bubble and crackle, many occasions need primary coat, the higher application that also affects this kind of material of cost.Therefore, development of new easy construction, good endurance and low-cost door and window joint filling sealing material are problem demanding prompt solutions.
Thermal power generation be take as main in China, within 2011, China consumes 19.5 hundred million tons of hundred million tons of electric coals altogether, and the coal sulphur content of China is higher, average out to 1%-2%, thereby every year because fire coal will discharge 2,000 ten thousand tons of above sulfurous gas, cause financial loss to reach hundreds billion of units, and wherein coal fired power generation is exactly the discharger of maximum sulfurous gas; Therefore the Chinese government attaches great importance to the environmental practice of coal fired power plant flue gas desulfurization, and 2010 Nian， China have the coal fired power generation unit of 4.6 hundred million kilowatts that flue gas desulfurization (FGD) unit is installed, and within 2010, China's desulfurated plaster quantity discharged reaches 5,200 ten thousand tons.China produces 1100 ten thousand tons, phosphate fertilizer per year, also will discharge 4,000 ten thousand tons of phosphogypsums that belong to chemical gypsum with desulfurated plaster together every year, and phosphogypsum must be accumulated for many years and reached several hundred million tons.The output of China's plaster of paris in 2007 is more than 5,000 ten thousand tons (wherein 3,500 ten thousand tons for cement setting retarder, other is converted into semi-hydrated gypsum powder or Thistle board gypsum block etc.); Even if so all chemical gypsum has all replaced the plaster of paris, still may there be desulfurated plaster and the phosphogypsum of several ten million tons to utilize.As can be seen here, if new purposes is not innovated, opened up to the treatment technology of chemical gypsum, comprehensively fully utilize, must cause secondary pollution.
At present, the approach that utilizes that desulfurated plaster and phosphogypsum are common has: 1) for manufacture of cement, substitute the plaster of paris in manufacture of cement as cement adjustable solidification agent utilization; 2), for gypsum building material product, calcining can be produced plaster of Paris after pretreatment, in order to manufacture Thistle board, fibrous plaster, hollow lath, holllow building block etc.; 3) for improveing soil.
The chemical gypsums such as desulfurated plaster, phosphogypsum of take prepare as main gelling material recycling that gypsum base door and window joint filling seal sand slurry is waste gypsum provides a new approach that utilizes, and is not only conducive to pollution treatment and reduces discharging, reduces material cost; The novel water tolerance gypsum base seal sand slurry of preparation can effectively solve the leakage problems of building doors and windows, is also conducive to ease contradictions, and development promotes social harmony.
Application number is that 201310062179.9 Chinese patent discloses cement based without shrinking door and window joint filling seal sand slurry and preparation method thereof and constructional method, and sealing mortar is formulated by weight by following component: cement 100, active admixture 0-80, water reducer 0.01-10, hardening accelerator 0.01-10, adjustable solidification agent 0.01-10, swelling agent 0-25, binding agent 0-30, air entrapment agent 0-10, plasticity-retention agent 0.01-30, hydrophober 0.01-10, starch ethers 0-5, powder filler 0-150, aggregate 0-300.
This kind of door and window seam sealing material has many advantages, but also has some shortcomings part, for preventing cement slurry shrinkage cracking, in slurry, admixture has swelling agent to divide, this component easily causes the loss of sealing fluidity of slurry, and when adopting extrusion molding construction, slurry resistance increases, to having relatively high expectations of preparation of construction.For above deficiency, make full use of waste gypsum lightweight, sclerosis is not shunk, workability is good and cost is low advantage, adopting the trade wastes such as desulfurated plaster, phosphogypsum is the novel gypsum base door and window seam joint filling sealing material that main gelling material can prepare, compare with cement based sealing material, the present invention has lightweight, and workability is good, extrudes resistance little, the feature such as construct easier, this material also has the advantages such as fire line is good, sound-absorbing, damping.Meanwhile, adopt waste gypsum place of cement can reduce in a large number energy consumption and the Carbon emission in cement production process as main gelling material, and can reduce material cost.Therefore the present invention is a kind of low-cost environmental friendliness shaped material.
Summary of the invention
