Abstract
The invention provides an anti-cracking additive which is characterized by comprising the following components according to proportions as follows: 40-70wt% of ground slag, 10-20wt% of silicon powder, 5-15wt% of iron powder, 3-8wt% of aluminum powder, 5-15wt% of quartz powder, 1-3wt% of anti-cracking anti-permeability anti-abrasion fiber, 1-3wt% of glass fiber and 3-8wt% of expanding agents. In a surface coating of an outer wall of a building, after cement mortar, putty and the like are matched into the anti-cracking additive, a coating layer can not generate any cracks in the initial period, the bonding strength is more than 0.5MPa, the coating layer can not strip, does not generate bubbles and cracks, and is not obvious in color change in temperature resistance deformation experiments, the water permeability of the coating layer is 0.5mL, and simultaneously, the coating layer dose not generate cracks, can not strip and is not obvious in deformation through an impact resistance experiment. In addition, as waste slag is taken as a main raw material of the additive, the cost is low, and also the industrial waste-slag can be recycled effectively and utilized comprehensively, so that the waste material can be recycled, and the serious problems of large land occupying, serious environment pollution and the like caused by the stacking of the slag can be solved fundamentally.
Description
Technical field
The present invention relates to a kind of additive, especially a kind of anticrack additive that is used on the external walls such as concrete, putty, mortar.
Background technology
Be to increase the decorating building effect, protection materials for wall, outside the building wall making cement screed or putty layer usually.Owing to surperficial material of construction such as sand-cement slurry, putty can produce be full of cracks because of the coefficient of expansion of aquation drying shrinkage, differing materials is inequality etc., thereby crackle appears in the top coat that causes being done, and in case crackle has been arranged, not only influence facade, even more serious is to cause rain leakage because of the crack, thereby influences the interior finish of buildings.Therefore, the top coat cracking is the problem that building trade is difficult to break through always, for overcoming the building surface cracking, though people have developed different materials, as flexibility and Elastic reactance crack putty or the like, but still have problems such as cost height, effect of anti-cracking be not good, and fundamentally do not solve the skin topcoating---cement sand bed or putty layer rimose problem.In addition, industrial waste slags such as the plumbous zinc ore slag after the smelting, copper mine slag, iron ore slag, major part is all handled with the stacking form, have only small part to be recovered utilization, and the recycling amount is quite limited, not only takies limited land resources, and long-term stacking will be given bringing environmental pollution with stacking.Therefore, must be improved prior art.
Summary of the invention
For overcoming skin topcoating---rimose problems such as cement sand bed or putty layer, the invention provides a kind of anticrack additive.
The present invention is to provide a kind of like this anticrack additive, it is characterized in that component is:
Slag powders 40～70 wt%
Silica flour 10～20 wt%
Iron powder 5～15 wt%
Aluminium powder 3～8 wt%
Silica powder 5～15 wt%
Red strong silk 1～3 wt%
Glass fibre 1～3 wt%
Swelling agent 3～8 wt%.
Described slag powders is in the plumbous zinc ore slag after smelting, copper mine slag, the iron ore slag one or more, and is broken into 200 purpose fine powders.
Described silica flour, iron powder, aluminium powder, silica powder, red strong silk, glass fibre, swelling agent are commercial product.
Anticrack additive provided by the invention makes through following method: with above-mentioned slag powders, silica flour, iron powder, aluminium powder, silica powder, red strong silk, glass fibre, swelling agent mixing and stirring, promptly get the anticrack additive product.
Press anticrack additive: skin with addition of using in the topcoating to skin, can effectively prevent skin topcoating cracking with anticrack additive of the present invention with the mass ratio of topcoating=1:4～6.
The present invention has following advantage and effect: adopt such scheme, make the present invention's anticrack additive have stronger cracking resistance effect, in exterior wall surface coating at buildings, as sand-cement slurry, putty etc., after allocating the present invention into, coating initial stage drying does not produce any crackle, cohesive strength is greater than 0.5MPa, and coating is tested through temperature-change resistance, does not peel off, non-foaming, flawless, there is not obvious variable color, the coating water-permeable is 0.5mL, simultaneously coating is through impulse withstand test, flawless, nothing is peeled off, not obviously distortion, in addition, main raw material of the present invention is the depleted slag, not only cost is low, but and efficient recovery and fully utilize this trade waste of slag, making it turns waste into wealth, fundamentally solving slag, to stack the floor space brought big, serious problems such as contaminate environment.
