Description
Technical field
The invention belongs to cement adjuvant technical field, be specially a kind of modified cement grinding aid.
Background technology
Cement grinding aid is a kind of chemical additive improving cement grinding effect and performance, can significantly improve cement unit-hour output, each length of time strength of cement, improve its mobility.Cement grinding aid significantly can reduce the electrostatic adhesion bag ball phenomenon formed in grinding process, and can reduce the again coalescent trend of the ultra-fine grain formed in grinding process.Cement grinding aid also significantly can improve cement fluidity, improves the grinding effect of grinding machine and the grinding efficiency of powder separating machine, thus reduces grinding energy.The cement using grinding aid to produce has the coalescent trend of lower compacting, thus is conducive to the handling of cement, and can reduce the wall cling phenomenon of cement silo.As a kind of chemical additive, grinding aid can improve concrete scroll and excite aquation power, thus improves cement early strength and later strength.The problems such as at present, all existence stabilizability is poor for existing grinding aid, and the variation for milliosmolarity is responsive, and the consistency of cement is bad.
Summary of the invention
For the problems referred to above existed in prior art field, the object of the invention is to design the technical scheme that a kind of modified cement grinding aid is provided, it is conducive to fine-grinding and superfine pulverizing, be conducive to grinding machine and improve output, be conducive to reducing grinding energy, be conducive to improving grog utilization ratio, be conducive to the production improving special cement, be conducive to the energy-saving and emission-reduction of Cement industry.
Described a kind of modified cement grinding aid, is characterized in that being made up of the following material of parts by weight: polymerized polyalcohol 20-30 part, lignin-base hydramine 10-30 part, sodium soap 2-10 part, polytetrafluorethylepowder powder 5-10 part, solid phosphoric acid aluminum dihydrogen 1-5 part, gelatin 1-4 part, sucrose 2-6 part; The particle diameter of described solid phosphoric acid aluminum dihydrogen is 50-80nm.
Described a kind of modified cement grinding aid, is characterized in that: polymerized polyalcohol 22-28 part, lignin-base hydramine 15-25 part, sodium soap 4-8 part, polytetrafluorethylepowder powder 6-9 part, solid phosphoric acid aluminum dihydrogen 2-4 part, gelatin 2-3 part, sucrose 3-5 part; The particle diameter of described primary magnesium phosphate is 50-80nm.
Described a kind of modified cement grinding aid, is characterized in that: polymerized polyalcohol 25 parts, lignin-base hydramine 20 parts, sodium soap 5-7 part, polytetrafluorethylepowder powder 7-8 part, solid phosphoric acid aluminum dihydrogen 3 parts, 3 parts, gelatin, sucrose 4 parts; The particle diameter of described primary magnesium phosphate is 60-70nm.
Described a kind of modified cement grinding aid, it is characterized in that described nanometer aluminium dihydrogen phosphate adopts following methods preparation: by wet ball grinding 10-20 hour under solid phosphoric acid aluminum dihydrogen powder room temperature, by aluminium dihydrogen phosphate powder for drying after ball milling, obtained particle diameter is the nano level aluminium dihydrogen phosphate of 50-80nm.
Described polymerized polyalcohol, as the novel material of cement grinding aid, can reduce grinding aid production cost more than 10%; Substitute alcohol component in original formulation completely, reinforced effects is better than alcohols, and after substituting, the cost of cement grinding aid product is lower, performance is more excellent, adaptability is stronger.
Described lignin-base hydramine, its grinding-aid effect can reach 88% of trolamine, to cement bending and compressive strength effect close to trolamine, and has good suitability to different grogs.
Described polytetrafluorethylepowder powder, has outstanding not viscosity, is fabulous non-stick material, and this performance makes again the surface adhesive of it and other objects very difficult.The add-on of polytetrafluorethylepowder powder has special restriction, too much the very few use properties that all can affect auxiliary agent.
Described solid phosphoric acid aluminum dihydrogen, at normal temperatures with refractory aggregate, within after the mixing such as stiffening agent constant temperature 4-24 hour between 90-110 ° of C, form high-adhesive-strength, after 350-500 ° of C is dried, just there is high resistance folding, resistance to compression, hydration resistance, also do not feel like jelly even if soak or boil in water.Along with aluminium dihydrogen phosphate particle diameter reduces, the time of coagulation of cement shortens to some extent, and degree of mobilization reduces obviously; On ultimate compression strength impact significantly, particle diameter can reduce mean pore size and the porosity of cement to particle diameter, the early strength significantly improved, and improves cementitious material surface scum phenomenon simultaneously.
The difference of each component, content in above-mentioned cement, has significant impact to the performance of product.
Above-mentioned a kind of modified cement grinding aid, is conducive to fine-grinding and superfine pulverizing, and be conducive to grinding machine and improve output, ball mill output improves 25%; Be conducive to reducing grinding energy, be conducive to improving grog utilization ratio, cost-saving; Chamotte powder in cement substantially can complete hydration reaction in 20d, has all given play to intensity effect; Be conducive to the production improving special cement, be conducive to the energy-saving and emission-reduction of Cement industry.
