Abstract
The invention relates to a formula and processing technique for a composite material product, in particular to a formula and processing technique of a novel halogenide-cumming resistant magnesite greenhouse skeleton. The formula is characterized by comprising the following components in percentage by weight: 58 percent of craft-level magnesium oxide of which the content of magnesium oxide is 85 percent, 21.6 percent of craft-level magnesium chloride of which the content of magnesium chloride is 56 percent, 2 percent of polyvinyl alcohol, 0.6 to 1.6 percent of organic silicon water repellent, proper amount of 5-mesh-below fiberglass roving, and 17.5 percent of water. The complex formula and the technique of using the organic silicon water repellent to replace magnesium sulfate to realize hygroscopic absorption and inhibit the halogenide-cumming of magnesite products are adopted, so the process is simplified and the cost is lowered. The organic silicon water repellent can form a fine water repellent film on the surfaces of pores in the magnesite product, the inner surfaces of capillaries of magnesite product and the surfaces of the magnesite products. The film can also react with carbon dioxide in air to form a carbonizing film with stronger hydrophobic property.
Description
One, technical field
The present invention relates to a kind of prescription and complete processing of prescription and complete processing, particularly a kind of novel halogenide-cumming resistant magnesite greenhouse skeleton of composite product.
Two, technical background
Well-known magnesite product claims magnesium oxychloride cement product again, has fast solidifying, and cohesive force is strong, a little less than the alkalescence, characteristics such as intensity height, but also have poor water resistance simultaneously, very easily scumming directly influences the shortcoming or the deficiency of product strength and quality.Application number is the technical measures that alleviate deadweight that 200520121956.3 latest model magnesite greenhouse skeleton has only taked to be added with the polystyrene foam core, unresolved scumming problem; Application number is 200410024435.6 inhibition magnesite product scumming protection liquid, and employed industrial chemicals reaches more than 10 kinds, composition and complex process, equipment and technology cost height; Application number is the prescription and the complete processing of 01123570.5 magnesia cement big-canopy framework, its moisture adsorbent has adopted sal epsom, though the shortcoming of the moisture absorption frosting of product is improved to some extent, but the mixture that it must add paper pulp and glass fibre just can prevent the contraction and the cracking of product, the intensity of product descends to some extent, life-time service can deform, and effect is bad improved necessity.
Three, summary of the invention
The objective of the invention is to overcome many shortcomings of above-mentioned background technology, provide that a kind of cost is low, batching is simple, the prescription and the complete processing of handling ease, intensity height, surface halide accumulation resistance scum, harmless magnesite greenhouse skeleton.
The present invention is achieved by the following technical solutions, and its prescription proportioning (weight %) and complete processing are as follows:
(1) prescription proportioning (weight %)
The technology grade magnesium oxide 58% that contains magnesium oxide 85%; The artwork grade magnesium chloride 21.6% that contains magnesium chloride 56%; Polyvinyl alcohol 2%, organosilicon moisture repellent 0.6-1.6%, fiberglass gridding cloth 5 orders are following, in subtract an amount of; Water 17.5%.
(2) production technique is as follows:
1. magnesium chloride is added fully to dissolve in the entry and makes magnesium chloride brine,
2. polyvinyl alcohol is added fully to dissolve in 90 ℃ of water and make the aqueous solution that contains polyvinyl alcohol 6.7%
3. above organosilicon moisture repellent being added in 1,2 aqueous solution, what stir obtains solution No. 3
4. make pasty slurry with stirring in No. 3 liquid of magnesium oxide adding.
5. earlier smear one deck pasty slurry at mould inner surface, layer overlay fiberglass gridding cloth then, and make it fully soak into slurry, method is done 4 layers to 5 layers like this, requires every layer of fiberglass gridding cloth all will fully have thorough grasp slurry.With slurry mould is filled it up with floatingly at last, put into the thermostatic chamber solidifying formation, when thermostatic chamber keeps 30 ℃, got final product the demoulding in 8 hours, dry at normal temperatures maintenance can be used after 15 days after the demoulding.
Advantage of the present invention and positively effect:
1. the present invention adopts organosilicon moisture repellent to replace the sal epsom hygroscopic effect and suppresses complexity prescription and the technology that the magnesite product scumming is protected liquid, has simplified technology, has reduced cost.
2. organosilicon moisture repellent can be in the surface, space and the very thin hydrophobic membrane of kapillary internal surface formation of the inside of magnesia cement goods.Product surface also can form same hydrophobic membrane simultaneously, and this film can also form the stronger and competent especially carbonized film of hydrophobic nature with the effect of carbon dioxide in air gas, thereby has formed the very strong surface of hydrophobic nature, has improved the quality of product greatly.Both guaranteed that the product strength height can not be out of shape and ftracture, stable performance simultaneously is lasting again.
Four, embodiment
(1) (one) is listed identical in the prescription proportioning (weight %) and top three
Example one:
The technology grade magnesium oxide 58% that contains magnesium oxide 85%; The artwork grade magnesium chloride 21.6% that contains magnesium chloride 56%; Polyvinyl alcohol 2%, organosilicon moisture repellent 0.6%, fiberglass gridding cloth 5 orders are following, in subtract an amount of; Water 17.5%.
Organosilicon moisture repellent is less than 0.6% o'clock weak effect in this example, and 0.6% can use in the not king-sized area of humidity
Example two:
The technology grade magnesium oxide 58% that contains magnesium oxide 85%; The artwork grade magnesium chloride 21.6% that contains magnesium chloride 56%; Polyvinyl alcohol 2%, organosilicon moisture repellent 1.6%, fiberglass gridding cloth 5 orders are following, in subtract an amount of; Water 17.5%.
Organosilicon moisture repellent 1.6% in this example, can use in the area of high humidity. but the hydrophober ratio must not be greater than 2%. otherwise can to increase cost inadvisable.
(2) production technique: identical with the production technique in (two) in the front three
Claims (2)
1. the prescription of the prescription of a composite product and complete processing, particularly a kind of novel halogenide-cumming resistant magnesite greenhouse skeleton and complete processing, it is characterized in that: its prescription proportioning (weight %) is:
