Abstract
A self-leveling gypsum-based floor-leveling material for building is proportionally prepared from natural anhydrous gypsum, alkaline exciter, acidic exciter, water preserving agent, water decreasing agent and defoamer through grinding anhydrous gypsum, premixing others, mixing the anhydrous gypsum powder with the premixture, and stirring.
Description
Technical field
The present invention is applied to building material technical field, and what be specifically related to is a kind of gypsum base ground self-leveling alignment material and preparation method thereof.
Background technology
From levelling be a kind of be base-material with inorganic or organic gel gel material, do with admixture such as superplasticizer and thin river sand (quartz sand) etc. and mix the building ground alignment material that forms.After only need water cement ratio scope in accordance with regulations adds the water uniform mixing during use, behind mechanical pumping or the artificial construction, need be manually floating, form flat surface by slurry in self gravitation effect current downflow.With self-leveling material construction planeness height, saving of work and time is the ideal material that is used for the floor leveling construction.
In recent years, the common report of exploitation of the gravity flow flat products of various base materials is that base material is developed as the master but mainly concentrate on semi-hydrated gypsum, cement, epoxy coating etc.Still the natural dehydrated gyp-exploitation self-flatting ground making level material unmanned abundant, that grade is good with China's reserves.Because epoxy self-leveling coating cost is higher and use and transport inconvenience; It is big that the production of cement and semi-hydrated gypsum exists energy consumption, seriously polluted.And semi-hydrated gypsum is relatively poor from the levelling water tolerance.Do self-leveling material with natural anhydrite and need not calcining, energy-conserving and environment-protective, water tolerance is better than semi-hydrated gypsum, so the importance of more apparent its exploitation.
Summary of the invention
The natural dehydrated gyp-preparation that the objective of the invention is to use potential hydration activity takes advantage of water tolerance to improve, cost is lower, the simple gypsum-base self-flatting ground making level material of technology and develop its preparation technology.
A kind of gypsum-base self-flatting ground making level material that the present invention proposes, form the weight proportion scope of each component following (weight with natural anhydrous plaster powder and alkali-activator is radix) by natural dehydrated gyp-acidic activator, alkali-activator, water-holding agent, high efficiency water reducing agent, defoamer, thin river sand (or quartz sand)
Natural anhydrous plaster powder 80-90
Alkali-activator 10-20
Acidic activator 0.5-1.5
Water-holding agent 0.03-0.1
Water reducer 0.5-1.5
Defoamer 0.1-0.5
The thin river sand 0-100 of＜0.125mm
The used alkali-activator of the present invention is selected cement for use.Strength grade is 42.5
#More than.
Acidic activator comprises sylvite series exciting agent among the present invention, sodium salt series exciting agent, and transition metal sulfate can be any one or two or more mixing.During two or more mixing is any proportioning.
Water-holding agent adopts methylcellulose gum among the present invention, Vltra tears (HPMC), and hydroxyethylmethyl-cellulose (HEMC) can be any one or two or more mixing, is any proportioning during two or more mixing.
Water reducer is selected the melamine analog high efficiency water reducing agent for use among the present invention.
Anhydrite powder is for to utilize industrial ball mill grinding with natural dehydrated gyp-, and fineness is controlled at 200 mesh sieve surpluses less than 5%, and specific surface area is at 4000-5000cm
2/ g.
The preparation method of invention: realized by following steps: 1) natural anhydrite is utilized industrial ball mill grinding, fineness to be controlled at 200 mesh sieve surpluses less than 5%, specific surface area is at 4000-5000cm
2/ g; 2) measured alkali-activator by weight percentage, acidic activator, water-holding agent, water reducer, defoamer and the abundant pre-mixing of proper amount of gypsum powder that measures.The premix powder is even with the terra alba thorough mixing in mixer that measures in a large number.Self-flatting ground making level material.For adding the sand prescription, can add sand uniform mixing in mixer in thin river in the described mixture as required, packed back product.During on-the-spot the use, add water with the mixing water amount of water cement ratio 0.30-0.40 and stir.
The present invention adopts natural dehydrated gyp-to produce gypsum-base self-flatting ground making level material, natural dehydrated gyp-has potential hydration activity, need not calcine, under certain admixture excitation, its product has suitable characteristics of hardening strength height, water-tolerant, time of coagulation.Only need grinding, mixing because natural dehydrated gyp-need not be calcined, compare semi-hydrated gypsum base and cement-based self-leveling, save energy, minimizing are polluted, and the water reducer consumption is few, thereby reduce production costs, and improve the market competitiveness.Especially for semi-hydrated gypsum for the levelling, have water-tolerant, the more high feature performance benefit of intensity, so this product will occupy an important position in the levelling series product.
Specific embodiments
