Abstract
Provided are a calcium carbonate activating method and environment-friendly single-component putty. The calcium carbonate activating method comprises the steps that coupling reagents, namely, aluminic acid ester and stearic acid are added to calcium carbonate, and stirring and dipping are carried out to obtain activated calcium carbonate with a coupling reagent molecular layer formed on the surface of calcium carbonate. The environment-friendly single-component putty is prepared from, by mass, 5%-10% of 425 white cement, 10%-15% of organic filler, 65%-75% of inorganic filler and 9.7%-19.7% of additives. The inorganic filler is activated calcium carbonate obtained after treatment with the calcium carbonate activating method. The environment-friendly single-component putty has the advantages of being environmentally friendly, good in water resistance, high in crack resistance, high in strength, easy to polish, easy to construct due to the single component and low in cost.
Description
Technical field
The present invention relates to building material field, more specifically, the environment-friendly type single-component putty of the activated calcium carbonate after relating to a kind of calcium carbonate activation method and comprising this calcium carbonate activation method process of employing.
Background technology
Along with developing rapidly of building trade, the demand of material of construction constantly increases.Putty is as the indispensable operation together before priming, and the putty of excellent performance is the basis of whole procedure.Meanwhile, when a large amount of use putty, its cost and application property are also important Considerations.Existing elastic water-proof putty, be generally powder+liquid material two components to mix together in specific proportions, for two component, although there be good criticizing to scrape performance and more excellent physicals, but its construction is loaded down with trivial details, in construction process, proportioning and stir gimmick improper and very easily affect criticizing of putty and scrape effect is higher to the technical requirement of workmen.In addition, the cost of two ingredient elastic water-proof putty is higher.And existing single-component elastic water-proof putty exists: low, the easy dry linting of intensity; Flexible poor, easy to crack; Construct complicated, polishing difference etc. defect.Therefore, how to solve that existing putty cost is high, construction is complicated or the problem such as poor performance, developing and have good springiness and the high putty of intensity, is the technical problem needing solution badly.
Summary of the invention
In order to solve the problem and consider the requirement of environmental protection, the present invention is by the modification to mineral filler calcium carbonate in putty, and obtained have good elasticity, the environment-friendly type single-component putty of good dispersiveness, reinforcing and oil-absorption(number) and good application property.
Specifically, an aspect of of the present present invention provides a kind of calcium carbonate activation method, adds coupling agent Aluminate and stearic acid in calcium carbonate, and stirs dipping, obtains the activated Calcium carbonate forming coupling agent molecule layer at calcium carbonate surface.
Aforesaid method provided by the invention can activate existing calcium carbonate, according to superpolymer filler theory of pile, based on coupling agent, carries out comprehensively modifying activation treatment to calcium carbonate surface, to increase the surfactivity of calcium carbonate, increases its loading level.The surface modification activated Calcium carbonate used in the present invention is by adding coupling agent Aluminate and stearic mixture stirring dipping, calcium carbonate surface through process like this defines coupling agent molecule layer, calcium carbonate particles surface can be made to be changed to hydrophobicity by wetting ability, can combine more closely with organic polymer, the activated Calcium carbonate that surface forms coupling agent molecule layer can be obtained.
According to an embodiment of calcium carbonate activation method of the present invention, preferably, described calcium carbonate powders is put into activation equipment, after starting rotation, drops into and account for the described Aluminate of described calcium carbonate powders weight 1% and the described stearic acid of 1.5% respectively, after process 1h, the activation rate of described calcium carbonate reaches 100%, and oil-absorption(number) reaches more than 46.6%, and whiteness reaches more than 93.6, complete activation, obtained described activated Calcium carbonate.Calcium carbonate activation method described in this technical scheme, add Aluminate and stearic amount, and rotation limit, limit adds, and material can be made fully to be flooded and mix, and is a kind of preferred embodiment by test of many times and strict control of calculating.
According to an embodiment of calcium carbonate activation method of the present invention, preferably, after adding described Aluminate and described stearic acid, then drop into thinner, described thinner can make described Aluminate and described stearic acid more uniformly can be distributed in the surface of described calcium carbonate.In this technical scheme, auxiliary with thinner, then thinner and coupling agent can be made to carry out comprehensive activation treatment to calcium carbonate surface, the surfactivity of calcium carbonate can be increased further.
Another aspect provides a kind of environment-friendly type single-component putty, it is characterized in that, the component comprised and the mass percent of component are:
Wherein, the activated Calcium carbonate of described mineral filler for obtaining after calcium carbonate activation method process described in employing appeal either a program.
The above-mentioned environment-friendly type single-component putty that the present invention provides, because the activated Calcium carbonate that obtains after selecting to the invention provides the process of method effects on surface is as mineral filler, makes calcium carbonate have good dispersiveness, reinforcing and oil-absorption(number).Compared to common calcium carbonate powders, the activated Calcium carbonate through modification has less particle diameter, is conducive to improving dispersed and filling up ability; And by compound coupling method, modification is carried out to ordinary calcium carbonate, hydrophilic attribute is changed into hydrophobicity, calcium carbonate and organic filler can be made to combine more closely, strengthen the intensity of putty, simultaneously because single-component not only cost reduction, and application property is good, constructability.
According to an embodiment of environment-friendly type single-component putty of the present invention, preferably, described organic filler is urethane.In this technical scheme, because selecting by polyurethane material as organic filler, it has good elasticity, under the stirring, impact of waterpower, air-flow, can subtle change be there is in filler own form, this change in shape ensure that organic filler and mineral filler are inner, form good exchange of substance condition between outside, and this process is referred to as again " from breathing " effect of high-performance bio compatibility filling, can promote the biochemical reaction of microorganism.Further increase the elasticity of putty of the present invention, intensity and workability.
According to an embodiment of environment-friendly type single-component putty of the present invention, preferably, the component that described additive-package contains and the mass percent of each component in described environment-friendly type single-component putty are:
In the technical program, selecting above-mentioned characteristic additive and content thereof, can improve the elasticity of putty, intensity, rub resistance and workability further, is preferential embodiment.
