Description
Technical field
The present invention relates to a kind of coating, more particularly to a kind of cement lithin paint.
The invention further relates to the preparation method of above-mentioned cement lithin paint.
Background technology
Mankind's activity exacerbates volatilizees caused by environmental pollution, especially fossil energy and various manufacturing activities
Property organic compound (VOC) cause environmental pressure it is increasingly severe.It is coating row to reduce VOC content in air, reduce energy resource consumption
The problem of industry one is increasingly urgent, water paint, powdery paints, photocureable coating and high solid coating are as four big Novel rings
Guarantor's type coating turns into the direction of following paint development, and the environmental protection coating material of low temperature or even normal temperature cure is even more in the ascendant.
Cement, portland cement is often referred to, the use of water is curing agent, and normal temperature cure can be realized.This illustrates that cement is
A kind of environmental protection, the environment-friendly material of energy-conservation.But although cement is a kind of widely used environment-friendly material, light water
Mud is difficult to use as coating material.
First, cement color is relatively simple, due to containing the impurity elements such as iron in raw material, after high temperature sintering, absolutely mostly
Number cement is grey black, it is difficult to assign more abundant color.Want the cement of acquisition various colors, i.e., " coloured cement ", only
Can be by the way of white cement adds pigment.A large amount of gypsum (calcium sulfate) composition is contained in white cement, and gypsum is a kind of water-fast
The poor raw material of property.Therefore, want the light cement of acquisition water-tolerant, can only be produced by purer raw material, preparation
Cost is of a relatively high.
Secondly, even if light cement type has been made by using the mode of high-purity raw, due to normal silicate water
Mud has strict demand to the dosage of curing agent water in use.The ratio of mud refers to the dosage and cement of concrete reclaimed water
The ratio of dosage.The ratio of mud influences the compactness after the rheological property, cement mortar coherent structure and its hardening of concrete, thus
In the case where composition material is given, the ratio of mud is to determine concrete strength, durability and other a series of physical mechanical properties
Major parameter.Just there is an optimum ratio to cement, it is excessive or too small all the performances such as intensity can be made to be affected.And make
Used for coating, it is desirable to good workability, substantial amounts of water is added unavoidably, to improve its mobility.Plus cement slurry
Big as coating material surface area, moisture evaporation is fast, and the normal moisture required for theing cement solidifies also is difficult to ensure.These factors are tight
Ghost image rings strength of coating, limits application of the ordinary cement as coating.
Further, itself be difficult to obtain relatively thin coating in cement construction, shunk plus cement during condensation cure compared with
Greatly, it is easy to ftracture, influence attachment and the intensity of coating, also unsightly.
Above various reasons, use of the cement as coating material is had a strong impact on.It is with coloured cement, i.e., " colored
Cement ", used mainly as engineering material, for example lay color road, the still difficult " color water seen for coating material
Mud ".
The content of the invention
The present invention is to solve deficiency of the prior art, there is provided it is a kind of alkaline, inorganic, water-fast and clean, into
Film is good, and adhesive force is strong, the cement lithin paint that can be applied directly on ground.
A kind of technical scheme of cement lithin paint of the present invention is：
A kind of cement lithin paint, including aqua and colorant, the aqua each component percentage are respectively：Alkali
