Abstract
A kind of magnesite cement composite plate, it is to be formed by magnesium oxide, 45% magnesium chloride, sulfuric acid, tertiary sodium phosphate, water-resisting agent, emulsifying agent, talcum powder, 196 resins, methyl methacrylate, vinylbenzene and mineral filler mixing injection molding.Because add after polymer thing such as 196 resins and each set of dispense ratio align, gained cement is improved than traditional magnesite cement water tolerance, returns frost, deflection, yielding etc. all be improved.
Description
The present invention relates to the component of magnesite mud product, particularly the component of magnesite cement plate.
As everyone knows, the history in existing more than 100 year since the Sorel invention magnesite cement of France in 1867.For a long time, U.S., day, Soviet Union, English, moral west major industrial country are studied magnesite cement, though improving to some extent qualitatively, also exist poor water resistance for the magnesite cement plate, and it is serious to return frost, easily deflection and defect such as yielding.
The prescription that the purpose of this invention is to provide a kind of magnesite cement composite plate material, the water tolerance that makes this prescription make sheet material is improved widely, simultaneously, is difficult for returning frost, is difficult for deflection and not yielding.
Embodiment of the present invention are to carry out suitable adjustment to have added unsaturated polyester, methyl methacrylate quinone and vinylbenzene again on the basis of magnesia cement conventional formulation, make it play the effect that solid phase (5,1,8 phase) is filled out the cave, thereby not only improved the water tolerance of goods such as sheet material, thoroughly solved a difficult problem of returning frost, deflection, distortion simultaneously.Concrete prescription is as follows: (weight ratio)
Magnesium oxide 1,45% magnesium chloride solution 0.8-1.3, sulfuric acid 0.03-0.07, tertiary sodium phosphate 0.04-0.08, water-resisting agent such as NF
4Produce with NNO(Tianjin matrix material factory) common 0.03-0.05, emulsifying agent is produced as 0 π-10 and auxiliary reagent factory, 0S-15(Tianjin) common 0.02-0.03, talcum powder 0.2-0.3, (Chengdu resin processing plant produces 196 resins, major ingredient is a unsaturated polyester) 0.04-0.08, methyl methacrylate 0.02-0.03, vinylbenzene 0.04-0.06, mineral filler such as cinder or sawdust be 0.8-1.2 altogether.
Concrete method for making is divided into following three steps again
(1) preparation sal epsom, magnesium chloride mixture solution
Sulfuric acid and magnesium oxide and water, tertiary sodium phosphate are made into sal epsom, add 45% magnesium chloride solution again, being stirred to fully, dissolving forms mixing solutions.
(2) preparation water-resisting agent and emulsifier mix solution
Adding water-resisting agent and emulsifying agent are mixed with mixing solutions in hot water
(3) preparation of magnesite cement
Above-mentioned (one), (two) two kinds of mixing solutionss are carried out thorough mixing, and add mineral filler, talcum powder, add unsaturated polyester, methyl-propyl olefin(e) acid methyl esters, vinylbenzene thorough mixing at last and form.
(4) injection molding: form sheet material by the general method injection molding.
Following preference elaborates to the present invention, but does not limit the scope of the invention.
Example 1:(one) add 10 kilograms of hot water in universal container, 0.5 kilogram of tertiary sodium phosphate stirs.Add 10 kilograms of entry again in another general acid-resistant container, 10 kilograms in 0.6 kilogram in sulfuric acid and magnesium oxide are reacted into Adlerika, add 10 kilograms in 45% magnesium chloride again, stir to dissolving fully, get 41.5 kilograms of mixing solutionss.
(2) in another universal container with MF
4With each 0.25 kilogram of NNO, 0 π-10, each 0.1 kilogram of 0S-15 and 1 kilogram of thorough mixing of hot water get 1.7 kilograms of mixed solutions.
(3) with (one), (two) mixing of materials, add 10 kilograms of pulverized coal dregs, 0.5 kilogram of 196 resin, 0.2 kilogram of methyl olefin(e) acid methyl esters, 0.5 kilogram of vinylbenzene, 2.5 kilograms of talcum powder again, fully mix, be injection molded as sheet material then, the data that record see Table 1 and table 2.
Example 2: except that the amount of 196 resins changed 0.6 kilogram of 0.7 kilogram, 0.3 kilogram of methyl methacrylate, vinylbenzene into, all the other conditions were identical with example 1, and the gained magnesite cement is injection molded as sheet material, and the data that record also see Table 1 and table 2.

Advantage of the present invention:
1, its resistance to water of sheet material of making by magnesite cement of the present invention, to return frost, deflection, distortion all superior than existing magnesite cement sheet material.
2, method for making is simple, can adopt common apparatus, and raw material sources are abundant.
