Abstract
The present invention relates to a kind of material and the production method thereof of waterproof construction layer, and it adopts powdery magnesium oxide, phosphorus ore tailing, sand material and magnesium chloride, water to mix together.Its easy construction, level is few, cold construction, effect height; Cost is low, mostly adopts industrial waste, good economy performance, and the intensity height, quick solidifying, heat do not expand, coldly do not contract, do not rise drum, do not chap, and can coexist with the buildings life-span.
Description
The present invention relates to a kind of material and the production method thereof of waterproof construction layer.
No matter the waterproof layer in industrial at present or the civil building engineering, flooring as the house, major part all is based on the what is called of petroleum pitch coiled material " two felts, three oil " form, and its adopts and on-the-spotly to boil the thermal caking that pitch carries out between coiled material and coiled material and the basal plane etc. and construct.According to the relevant statistical information of the Ministry of Construction, two felts, three oily waterproof layers do not reach service requirements more than 70%, be difficult to guarantee construction quality, and this mainly shows: poor durability, work-ing life is short, and is easily aging, and high temperature is trickling easily down, chap easily during low temperature, big area often occurs, many places seepage phenomenon; Difficulty of construction is big, and working environment is abominable, and heat construction itself is difficult to ensure the quality of products, level is many again, also is subjected to the restriction of weather environment condition, and is time-consuming bothersome, and it is very serious to play the drum phenomenon, and it is of common occurrence the scald accident to occur; The scene boils that pitch naked light operation is dangerous, contaminate environment and impairing one's health.
The objective of the invention is to avoid the deficiencies in the prior art, and a kind of easy construction, durable in use, effective waterproof mortar product and manufacture method thereof are provided.
Can realize purpose by following technical scheme.Adopt powdery magnesium oxide, phosphorus ore tailing, sand material and magnesium chloride, sulfuric acid and water to mix together, their consumption is followed successively by 20~50%, 30~40%, 20~30%, 20~35%, 0.5~1% by weight, surplus is a water.
Content to the technical program is described in further detail in conjunction with the embodiments.
According to the mineral compound principle, present technique is with magnisite stone, and magnesium content 85~90%, the light-burned magnesium oxide that forms, opaque 120~140 orders become colloidal solution after it is met water and other composition mixes, as jointing compound; And adopt magnesium oxide as solidifying agent, byproduct when hydrated magnesium chloride is carnallitite system sylvite, contain magnesium chloride 60~65% in the residual salts behind the system sylvite, magnesium oxide and magnesium chloride brine mixture colloid, after chemical reaction and fusion reaction, be condensed into a kind of compound, this colloidal solution becomes the tight molecular compound of chemical structure through reactive polymeric, its chemical bond is very poly-close, no longer react after the curing with other material, keep molecular state closely, in magnesium chloride brine, add the ability to cure that commercial sulphuric acid can increase goods
Its consumption is less but can eliminate MgCl2.6H
2Impurity among the O and nitrate.
Other raw materials such as the industrial waste-phosphorus ore tailing powder in the stopping composition behind the employing production phosphate fertilizer, river sand can make cost reduce.
Use for convenient, above-mentioned raw material can be divided into the two parts: powdery stopping composition and pasty state material.Light-burned, 120~140 purpose magnesium oxide, 40% weight, 80 purpose phosphorus ore tailings, each three kinds of raw material of 30% weight of river sand with magnesium content 85~90% mix earlier, stir as stopping composition; Magnesium chloride 30% weight with magnesium content 60~65% is soluble in water, concentration is controlled at 18 °~25 °, stir, sulfuric acid 0.5% weight, magnesium oxide 5% weight that in solution, add 95% concentration subsequently again, stir once every half an hour in 6 hours, stirred every 1 hour in 6~12 hours in one time 12~24 hours to stir and once make the pasty state material every 2 hours.Two kinds of material can be packed respectively.When using at the scene stopping composition and pasty state material evenly be can be used for construction by allotment in 1: 1.The waterproof mortar that makes by this technology has better result of use.Deployed waterproof mortar should use up in four hours, otherwise the influence of sclerosis back is used.
The waterproof mortar that employing makes by this process has following advantage:
1, easy construction, level is few, and cold construction is ensured the quality of products easily, saves time and saves trouble, and effect is high, and is nonpoisonous and tasteless, harmless.
2, cost low, mostly adopt industrial waste, economy to be better than two felts, three oil, have the good social benefit.
3, have result of use preferably, the intensity height, quick solidifying is constructed and can be gone up the people after four hours and continue operation, and heat does not rise, and does not coldly contract, and does not play drum, does not chap, and structural capacity is strong, and is aging, can coexist with the buildings life-span.
Claims (2)
1, a kind of waterproof mortar, it is characterized in that: it adopts powdery magnesium oxide, phosphorus ore tailing, sand material and magnesium chloride, sulfuric acid and water to mix, preceding four consumption is followed successively by 20~50%, 30~40%, 20~30%, 20~35% by weight, and sulfuric acid 0.5~1% weight, surplus are water.
2, the preparation method of waterproof mortar as claimed in claim 1, it is characterized in that: it is with light-burned, 120~140 purpose magnesium oxide, 40% weight of magnesium content 85~90%, and 80 purpose phosphorus mine tailings, each three kinds of raw material of 30% weight of river sand mix earlier, stir as stopping composition; Refabrication pasty state material: soluble in water to 18 °~25 ° of concentration with magnesium chloride 30% weight of magnesium content 60~65%, stir, in solution, add sulfuric acid 0.5% weight, magnesium oxide 5% weight subsequently, stirred once every half an hour with interior in 6 hours, stirred once every 1 hour in 6~12 hours, stirred once every 2 hours in 12~24 hours; Stopping composition and pasty state material were mixed well by 1: 1 and are got final product.
