Abstract
The present invention discloses the method to prepare Ca-Mg powder and Si-Ca-Mg powder two kinds of plastering materials by using dolomite and Si-bearing dolomite as raw material respectively and trough the technologies of crushing, roasting and milling. The product belongs to the domain of the decoration, sculpture and production of fire-free wall or floor tile and has the the properties of fire proof and electric, sound and thermal insulation. The product features high hardness, clean white, smooth, wearability, endurable to washing color fast and non-peeling off.
Description
Calcium-magnesium powder, silicon calcium-magnesium powder plastering material belong to building field.
" dry powder " that generally make with the calcite raw material in the wall decoration of building field is the finishing material of plastering, and this product mixes the back construction with polyvinyl alcohol, and it has the pure white slick characteristics of the metope of making.Its maximum defective is that hardness is not high, and to drench slick surface, back be destroyed and variable color, vestige is arranged by water, even come off.Also not absorbed water in air year in and year out by water pouring person divides and flavescence and natural delamination.Organic plastic-blasting of new development in recent years, inorganic plastic-blasting all be unable to do without with " dry powder " smears bottom for scraping, so water-repellancy is still poor.Know also do not have the novel material of plastering that can overcome above-mentioned defective to be born on the market according to the domestic market investigation.
The purpose of this invention is to provide a kind of strong adhesion, hardness height, fire prevention, insulation, water resistance is good, immersion is insoluble does not come off, and can be used as the material of wall decoration, woodwork decoration, technology sculpture, unburned wall floor tile, the calcium-magnesium powder that serves many purposes, silicon calcium-magnesium powder plastering material.
The present invention realizes in the following way: with the high rock of calcic magnesium amount is raw material, is not more than 30cm by being broken into
3Stone, stone flour after, through high-temperature roasting again abrasive dust and the calcium-magnesium powder plastering material.Its technology: raw material-→ broken-→ 700～1200 ℃ of roastings-→ discharging-→ abrasive dust promptly gets product.
Calcium magnesium rock carries out roasting after an amount of silicon ore deposit is mixed in fragmentation again, then the roasting after product is carried out abrasive dust and silicon calcium-magnesium powder plastering material.Its technology: rock-→ broken-→ mix the silicon ore deposit-→ roasting 800-→ 1200 ℃-→ discharging-→ abrasive dust promptly gets product.
Calcium-magnesium powder plastering material and silicon calcium-magnesium powder plastering material, the material of choosing any one kind of them when construction can be realized purpose of the present invention with clear water and minor amounts of lubricants, retardant or lower concentration chlorination magnesium solution blending back construction.
The present invention has following advantage: this product has very high sticking power and hardness and wear resistance, and water resistance is good, does not fire in fire, and insulation, sound insulation, temperature control performance are arranged.When applying to wall plastering, metope is smooth pure white, and water is brushed its red dog nondiscoloration, do not come off towards drip washing, also can add alkaline coloured pigment when construction, makes it to become multi-colour wall surface, increases indoor aesthetic feeling.In addition, also can be used for the decoration of woodwork, produce decorative sheet, unburned decorative wall floor tile and technology sculpture etc. have wide application field.
Describe the present invention in detail below in conjunction with embodiment:
Embodiment 1, rhombspar is broken into 5～15m
3Crushed stone after drop into roasting in the radiation stove, through roasting for some time, the warm segment limit that stove Nei Wenduda is 800～1000 ℃ gets final product discharging.Raw material is from furnace roof charging, furnace bottom discharging cycle operation like this.Again through the ball mill abrasive dust, its fineness reaches 500 orders and promptly gets the calcium-magnesium powder product through the raw material after the roasting.
Embodiment 2, with rhombspar fragmentation 5～15cm
3Crushed stone, the weight of pressing the rhombspar fragment is added 5～15% siliceous carclazyte, drops into the reflection kiln roasting, the scope that reaches 900～1000 ℃ when maturing temperature gets final product discharging, it is milled to 500 order fineness again and promptly gets silicon calcium-magnesium powder plastering material.
The construction modulator approach: the said products is before construction, and need are constructed after being mixed into suitable denseness with it with clear water and minor amounts of lubricants, retardant or lower concentration chlorination magnesium solution.Its denseness is that employing is scraped wiping manipulation and coagulated the soup according to subject, constructional method decision, and it is rarer that the pneumatics gunite is adjustable.This products solidifying is fast, needs now with the current.
The compound method of magnesium chloride solution: according to different temperature, magnesium chloride is put into clear water dissolve, be modulated into different concentration, see following table for details:
Temperature and magnesium chloride solution concentration relationship table
| Temperature (℃) concentration (degree Beaume) | ? ????10 | ? ????15 | ? ????20 | ? ????25 | ? ????30 | ? ????35 |
| Join underlying material concentration | ????23 | ????22 | ????20 | ????18 | ????16 | ????16 |
| Join the capstock waviness | ????22 | ????20 | ????18 | ????17 | ????15 | ????16 |
Application Example 1, with calcium-magnesium powder of the present invention and silicon calcium-magnesium powder respectively with after the magnesium chloride solution blending, carry out indoor wall respectively with it and scrape each 100m of ash
2Test, back five days waters flushing of constructing, its metope is smooth pure white, hard, does not have obscission, does not also find the variable color stain in nearly so far six months.
Application Example 2, with product of the present invention with after the magnesium chloride solution blending, on three-ply-wood plate face, scrape ash and decorate, be soaked in water after it solidifies and tested in 24 hours, the red dog of scraping does not come off, and comparatively hard, draws with nail and does not see any recessed mark.
Claims (3)
1, calcium-magnesium powder, silicon calcium-magnesium powder plastering material, they get by calcic magnesium rock, calcic magnesium rock and siliceous carclazyte are mixed respectively, it is characterized in that calcium-magnesium powder is the meal after the rhombspar roasting; The silicon calcium-magnesium powder is the meal after rhombspar and the siliceous carclazyte roasting that accounts for its weight 5～15%.
2, calcium-magnesium powder according to claim 1, silicon calcium-magnesium powder plastering material is characterized in that the technology for preparing calcium-magnesium powder is: rhombspar-→ broken-→ 700～1200 ℃ of roastings-→ discharging-→ abrasive dust; The technology of preparation silicon calcium-magnesium powder is: rhombspar-→ broken, add siliceous carclazyte-→ 800～1200 ℃ of roastings-→ discharging-→ abrasive material.
