Description

The preparation method of light cellular partition board
The present invention relates to the preparation method's of building slab, particularly partition plate preparation method.
In house building, need various sheet materials, as inner partition plate, roof slab, balcony closure plate or the like, these sheet materials do not have the load-bearing requirement, but require light and shock resistance.A kind of GRC light cellular partition board is arranged at present, its main manufacturing raw material is low alkalinity cement and pearlstone, add that an amount of glue, enhanced foaming agent etc. are mixed into pulpous state, pour mould ram-jolt again into, treat behind the certain hour demoulding, but the expensive need of the low alkalinity cement price outsourcing that this product is required, the characteristic of pearlstone is too crisp, and therefore, the product of making is damaged easily, shock resistance, anti-bending strength are poor, the cost height.
The objective of the invention is to avoid the defective of prior art and provide a kind of preparation method of light cellular partition board, the light cellular partition board that adopts this method to produce to have that the material source of making is extensive, cost is low to society.Characteristics such as breakage rate is few, the shock resistance anti-bending strength is good.
The technical solution used in the present invention is as follows: (a). get flyash, magnesium oxide, the Portland cement metering feeds intake and is mixed and made into filler; (b). get the metering of industrial glue, magnesium chloride saltwater brine and feed intake to mix to stir and carry out the emulsification modification and handle and make gelifying agent; (c). get rosin, industrial gelatine, sodium hydroxide, puffing foaming agent, water metering and feed intake and mix the post-heating fusing and make stoste, add 30-50 times of water with 1 part of stoste again and get blisters and make puffing foaming liquid; (a) and (b), (c) three kinds of prefabrications are dropped into by weight percentage:
Filler 60～70%
Gelifying agent 18～25%
Expanding foam solution 10～20% carries out stirring at low speed after mixing, through neutralization, expanded back the mashed prod that foams; In preprepared mould, carry out limit cast, limit laying enhancing aggregate then and imbed the enhancing pipe; Solidified at normal temperatures 4-24 hour, and rebuild the corner behind the finally demould and fly hair and promptly make this product.
Each composition input amount (weight percent) of described filler:
Flyash 30～40%
Magnesium oxide 50～60%
Cement 5～15%
Each composition input amount (weight percent) of described gelifying agent:
Industry glue 5～10%
Magnesium chloride saltwater brine 82～88%
Each composition input amount (weight percent) of described puffing foaming liquid:
Rosin 8～12%
Industry gelatine 8～12%
Sodium hydroxide 2～4%
Puffing foaming agent 24～28%
Water 45～57%
Churning time when described gelifying agent prepares is 10～15 minutes.
When industrial glue takes off limit, magnesium chloride saltwater brine capping, also need allocate liquid sal epsom 5～10% into.
Filler, gelifying agent, mixed stirring at low speed time of puffing foaming liquid are 5～10 minutes.
Aggregate is selected for use and is looked the inner, external wall different situations, and what be used for interior wall is 32-36 purpose medium-alkali glass fiber grid cloth, and what be used for exterior wall is 3 2-36 purpose wire cloths.
Strengthen pipe and can adopt steel pipe or PVC plastics tubing.
The light cellular partition board of the preparation method's manufacturing that proposes by the present invention and the over-all properties of prior art GRC plate are compared as follows:
Project The present invention The GRC plate
Main raw material Flyash, magnesium oxide Low alkali cement, pearlstone
Comprehensive cost 30 yuan/M 2 40 yuan/M 2
Weight ??30kg/M 2 ??35kg/M 2
Anti-impact force The 30kg sand pocket distance that falls The 10kg sand pocket distance that falls
Transportation Energy is put down and is lifted, breakage rate is few Forbid flat to lift, the breakage rate height
Construction Construction process can splice tenon more than 3 meters damaged lacking High inapplicable more than 3 meters tenon assembly of construction process breakage rate presses
Effect is installed Defening effect is good Defening effect is poor
By subordinate list as can be known, light cellular partition board by the present invention's preparation obviously is better than the GRC plate, it is abundant not only to make material source, the utilization of waste material of can gathering materials on the spot, reduce environmental pollution, cheap for manufacturing cost, have in light weight simultaneously, the intensity height, shock resistance is good, fire prevention, moistureproof, sound insulation, can follow closely, saw, characteristics such as plane, wiring conduit is installed, door and window, it is firm veneer such as to hang, easy construction is rapid, to improving fertile beam, fertile post, deep foundation, reduce comprehensive cost, increasing usable floor area has remarkable economic efficiency, can be widely used in industry, covil construction non-load bearing wall internal partition, and commerce and trade market, the hotel, the dance hall, high-rise mansion dividing wall and decoration.
Below in conjunction with embodiment the present invention is described in detail again.
The preparation method of light cellular partition board: at first carry out the inspection of raw and process materials, the magnesium oxide MgO magnesium content that wherein prepares filler adopts the product of the high village, Dashiqiao City, Yingkou, Liaoning magnesia unslacked factory more than 86%.Portland cement is with 400-500 number.The industrial glue of preparation gelifying agent adopts 106 glue or 107 glue, is produced by Qiu's mountain pass town, Ningbo glue factory, and the magnesium chloride saltwater brine that plays bonding effect is magnesium chloride hexahydrate MgCl 26H 2O, magnesium content are more than 46%, and proportion is 26 ℃ of-31 ℃ of mother-in-law U.S. degree, adopt saltern, Tanggu, Tianjin or Lianyun Harbour Huanghai Sea chemical general factory product.The one-level rosin that the rosin of preparation puffing foaming liquid adopts Jiangxi, Yunnan to produce is powdery.The one-level gelatine that gelatine adopts Deqing to produce is particulate state.The east of a river, Ningbo City Chemical Factory of Daily Use tailor-made product is adopted in the puffing foaming agent.
When the preparation gelifying agent, when industrial glue takes off limit, during magnesium chloride saltwater brine capping, need allocate liquid sal epsom MgSO4 5-10% into, purpose is to make the gelifying agent of making can not return halogen, thereby veneer firmly and is not come off.
The cast front template is placed smooth, just puts by product specification size quantity standard with the angle square length bar, and connects tight then fixing with the anchor fastening.Must tight four jiaos during cast put in place, remove clout, aggregate is laid smooth four jiaos and is put in place, and intubate is smooth, and the plate face needs little repeatedly shaking to draw together flatly, must place wood, iron built-in fitting when making the cast of door and window wallboard.Cast after fixing 4-24 hour, summer, set time was short because of the temperature height, and winter, temperature was low, and set time is long.Lifting is wanted steadily during the demoulding, should edge-on carrying, and tube drawing bench will become horizontal with plyer, control trombone slide speed, slow earlier back is strictly on guard against that drawing crack scraps soon.Cut off sheet material four limits during trimming and fly hair, check whether planeness is up to state standards.
