Abstract
The invention provides mono-component powdery high-strength water-resistant putty. The putty is mainly prepared from the following raw materials: heavy calcium carbonate, ash calcium powder, white cement, hydroxypropyl methylcellulose, redispersible latex powder, lignocellulose and aluminum-magnesium silicate. A preparation method for the putty comprises the steps: weighing all the raw materials according to composition ingredients, and grinding the raw materials, wherein the grain size of the ground raw material is 350-450 meshes; putting the ground raw material into a material blending tank, and carrying out preliminary uniform stirring; feeding the uniformly-stirred raw material to a horizontal mixer through a screw conveyor, carrying out mechanical mixing, then, feeding the mixture to a vertical mixer through a screw, and carrying out mechanical mixing, so as to prepare a dry-powder mixture; and finally, putting the dry-powder mixture into an exhaust chest so as to exhaust air from the mixed raw material, and filling the exhausted mixed raw material into bags. The putty has the beneficial effects that the putty has the characteristics of high water resistance, high hardness and high adhesion and meanwhile has the advantages of high yellowing resistance, alkali resistance, frost resistance, no toxicity, odorlessness, no environmental pollution and the like. After construction, in case of being exposed to water and moisture, the putty does not peel, does not shed, does not grow black spots and is long in service life.
Description
[technical field]
The present invention relates to building material technical field, be particularly a kind ofly applied to high waterproof, high rigidity, the high adhesive force powdery putty of scraping the bottoming of Herba Phaii tankervilliaes inner-outer wall.
[background technology]
Putty powder is a kind of material of construction of large usage quantity in building decoration, and putty powder must be used before body of wall swabbing to carry out bottoming to body of wall.Tradition putty powder mainly adopts white cement and sierozem power to be raw material, to solidify by self and the carbonic acid gas absorbed in air generates stable calcium carbonate, therefore in traditional putty powder, the calcify reaction of sierozem power (calcium hydroxide) mainly occurs in the top layer of putty powder coating, and also there is a large amount of unstable calcium oxide and calcium hydroxide in the internal layer of coating, thus cause traditional putty powder coating to there is following problem: 1. difference of hardness: calcification rate is not high, only have coating top layer harder, internal layer hardness is low; 2. water resistance is poor: the water capacity outside coating easily through coating epidermal penetration to internal layer, make that coating is softening bubbles; 3. sticking power is not strong: because the internal layer quality of coating is softer, and coating to be easy to after making moist or being heated foaming, long blackspot, to ftracture and then come off.
[summary of the invention]
The present invention is directed to problems of the prior art, provide a kind of and there is high waterproof, high rigidity, the powdery putty of high adhesive force and the preparation method of this powdery putty.This powdery putty has yellowing, the anti-alkali of high resistance, frost resistance simultaneously, and the advantage such as nontoxic, tasteless, non-environmental-pollution.Construction after makes moist by water, also non-scale, do not come off, not long blackspot, long service life.
For achieving the above object, the technical solution adopted in the present invention is:
A kind of single-component powdery high-strength waterproof putty, forms primarily of following raw material: sierozem power, water-ground limestone, Vltra tears, redispersable latex powder, lignocellulose, white cement, neusilin.
Further, preferred version of the present invention is: a kind of single-component powdery high-strength waterproof putty, the weight percent of each constitutive material is: sierozem power 10 ~ 20%, water-ground limestone 40 ~ 60%, Vltra tears 0.2 ~ 0.6%, redispersable latex powder 0.5 ~ 1.5%, lignocellulose 0.2 ~ 0.8%, white cement 25 ~ 40%, neusilin 0.1 ~ 0.4%.
Further, preferred version of the present invention is: a kind of single-component powdery high-strength waterproof putty, the weight percent of each constitutive material is: sierozem power 15%, water-ground limestone 50%, Vltra tears 0.4%, redispersable latex powder 0.9%, lignocellulose 0.5%, white cement 33%, neusilin 0.2%.
Beneficial effect of the present invention: this single-component powdery high-strength waterproof putty has the characteristic of high waterproof, high rigidity, high adhesive force, has yellowing, the anti-alkali of high resistance, frost resistance simultaneously, and the advantage such as nontoxic, tasteless, non-environmental-pollution.Construction after makes moist by water, also non-scale, do not come off, not long blackspot, long service life.Compared with putty powder existing on market, there is extremely outstanding cohesive strength, the longer open hour, excellent alkali resistance, attached property binding property, folding strength, plasticity-, wear resisting property and application property, putty homogeneous, stable, not stratified and bleed, has the characteristics such as stronger snappiness.
The present invention provides the method for this single-component powdery high-strength waterproof putty of preparation simultaneously, and concrete steps are:
1) get each raw material by composition component and carry out attrition process, processing granularity is 350 ~ 450 orders;
2) raw material after attrition process is put into spice groove, tentatively stir;
3) raw material stirred is sent into flat mixer through spiral shell fortune machine, after mechanically mixing, then be transported to post-type mixer through screw rod, after mechanically mixing, in dry powdered form;
4) air that mixing raw material discharged by gas outlet chamber is finally put into, filling one-tenth bag.
The further preferred version of this preparation method is step 3) described in the time of mechanically mixing in flat mixer be 15 minutes, the mechanically mixing time in post-type mixer is 15 minutes.
The advantage of this preparation method: preparation flow is simple, and easy and simple to handle, the equipment of use is industrial common equipment, with low cost, is suitable for scale production and popularization.
