Description
The present invention relates to the presoma system of aqueous composition, this composition of preparation and described composition is applied to the administration system of surface or matrix as for example coating.
Soluble silicate is widely used as tackiness agent, coating and binding material.Although itself solvability is valuable in many application, yet be disadvantageous to some application, for example the water-repellancy of structure, integrity and intensity are considered to those necessary application.
Existing a large amount of effort make silicate in above-mentioned composition minimumization of solubleness, for example by adding metal (as calcium and magnesium) salt.Then, adding this salt will obtain precipitation forms rather than have contiguous network shape constructed products.The soluble salt that forms in the precipitin reaction is to the physical integrity of the film that applies, thereby final unfavorable to the intensity of products obtained therefrom.
These factors have suppressed silicate in the purposes that for example prepares in the fire retardant coating compositions.Fire retardant coating compositions can be widely used in the building maintenance industry, for example is used for wherein before or after flammable material of construction is attached to building structure.The example of combustible matl is polymkeric substance watt and wall dunnage, as by polystyrene foamed or urethane plastic with comprise polymkeric substance that the matrix material of this plastics forms watt and wall dunnage.Timber, wood chip and paper base material also can have benefited from this application of paints.Be contained in the so-called expansion coating that has in this class fire retardant coating compositions, its part is by being heated or meeting its provide protection of fire expansion performance.
