Abstract
The present invention discloses a modified magnesium cement, which comprises the following raw materials by weight: 100 parts of magnesium oxide, 40-150 parts of a magnesium sulfate aqueous solution having a concentration of 30-55%, 0.1-15 parts of a modifier, and 0-300 parts of a filler, wherein the modifier is citric acid or sodium citrate. According to the present invention, the time of the reaction of the magnesium oxide in the magnesium cement and the magnesium sulfate aqueous solution can be effectively shortened, the magnesium cement cementing strength is high, the compression resistance of the product is good, the rigidity of the product is strong, and the modified magnesium cement can meet the use requirements in fields of industry, agriculture, building, building materials, civil, and the like.
Description
Technical field
The present invention relates to the magnesium cement material that the field such as industry, agricultural, building, building materials, civilian uses, particularly one kind changes
Property magnesium cement.
Background technology
General magnesium cement is made up of magnesia and magnesium sulfate mix, its have light weight, fire prevention, rate of set it is fast, every
Audio fruit is good, the features such as adiabatic efficiency is high, but magnesium cement in the curing process thermal expansivity is strong, be easily deformed and ftracture, machinery
Low intensity, therefore the promotion and application of this magnesium cement are limited, so as to pass through to develop the characteristic that modifying agent changes magnesium cement.
The content of the invention
It is intrinsic in order to overcome the shortcomings of magnesium cement, the performance of high-magnesia cement is put forward, the present invention provides a kind of modified magnesium-cement.
The technical solution adopted for the present invention to solve the technical problems is：A kind of modified magnesium-cement, the cement is by following
The raw material composition of parts by weight：100 parts of magnesia, concentration are magnesium sulfate solution 40-150 parts, the modifying agent 0.1- of 30%-55%
15 parts, inserts 0-300 parts, the modifying agent is citric acid or sodium citrate.
Wherein：The modifying agent is aluminum sulfate, alum, aluminium dihydrogen phosphate, waterglass, ethylenediamine tetra-acetic acid, hydroxyl
The mixture that a kind of and citric acid in ethylidene diphosphonic acid mixes.
Wherein：The modifying agent is aluminum sulfate, alum, aluminium dihydrogen phosphate, ethylenediamine tetra-acetic acid, the phosphorus of hydroxy ethylidene two
The mixture that a kind of and sodium citrate in acid mixes.
Wherein：The inserts is the one kind in flyash, silicon ash, slag, wood chip, land plaster, dolomite dust, shale powder
Or two kinds.
The invention has the beneficial effects as follows：Modifying agent effectively accelerates the anti-of magnesia and magnesium sulfate solution in magnesium cement
Between seasonable, the cement cementitious intensity height of magnesium is made, product compressive property is good, and the rigidity of product is strong, and meets industry, agricultural, builds
Build, building materials, the field such as civilian use.
