Chrysotile or chrysotile-containing serpentinite containing chrysotile is treated to convert the chrysotile contained therein into a non-asbestos material, so that the non-asbestos material is used as a material that can be recycled safely and is effective from the view point of environmental protection.[Means for Solving Problems] A curable composition characterized by containing at least a porous fibrous amorphous silica obtained by decomposing chrysotile or chrysotile-containing serpentinite with acid to substantially eliminate an influence of asbestos on living body, and a reinforcing fiber. The curable composition preferably contains a surfactant and a thickener and / or a filler and / or a colorant or an air-hardening material and / or water-hardening material and a thickener. The composition preferably contains 15 to 100% of the porous fibrous amorphous silica obtained by decomposing the chrysotile or the chrysotile-serpentinite with acid, 0 to 75% of a slaked line, 0 to 3% of a thickener, and 0 to 10% of a pulp.

A biocidal film-forming composition, preferably a paint, is disclosed, comprising hydrated lime, alkaline potassium salt, and a non-ionic polyolefinic latex resistant to hydrated-lime induced coagulation and phase separation. Also disclosed is the method of making certain such composition wherein hydrated lime is admixed with a non-ionic polyolefinic ester latex with agitation and continuing such agitation until hydrolysis of the ester is substantially completed and rheology of the composition is stabilized and the incidence of gelation is eliminated.

The invention relates to coating agents on the basis of one or more mineral binders, one or more polymers, one or more fillers and optionally one or more additives, characterised in that 2 to 30% by weight of lime, based on the dry weight of the coating agent, is contained in the coating agent as mineral binder.

The invention discloses a manufacturing method for a pure natural decorative coating of interior and exterior walls of buildings. The method comprises the following steps: weighting the following raw materials by weight percent: 5-10% of glutinous rice flour, 40-55% of red clay, 5-10% of husk, 15-20% of lime and 20-30% of water; crushing the glutinous rice flour and gelatinizing under high temperature, thereby acquiring glutinous rice slurry; grinding the lime to 325 meshes or above, thereby acquiring lime powder; grinding the red clay to red clay powder at 250-350 meshes or above; cooking and disinfecting the husk under high temperature, thereby acquiring disinfected husk; dispersing and stirring the glutinous rice slurry, lime powder, red clay powder, disinfected husk and water and packaging, thereby acquiring the coating. According to the invention, the coating is prepared from various natural raw materials, so that the coating is nontoxic and harmless, can be used for decorating the interior and exterior walls of buildings, has the characteristics of simplicity in operation, high adhesive property, quick drying, waterproof and damp-proof effect, non-scaling and non-falling effect, no toxicity, no harm, no pollution and natural color and can achieve the heat-insulating, heat-preserving and soundproof functions when the coating is used for decorating the interior and exterior walls of buildings.

Asphalt-based coating compositions and surfactants. The asphalt-based coating compositions have improved performance and comprise asphalt, clay, and a propoxylated alcohol-based ether amine salt surfactant.

Chrysotile or serpentine containing chrysotile is treated to convert the chrysotile contained therein into a non-asbestos material. The non-asbestos material is a useful material which can be safely reclaimed and used. It is effective from the standpoint of an environmental measure. [MEANS FOR SOLVING PROBLEMS] A curable composition characterized by at least containing reinforcing fibers and porous fibrous amorphous silica which is obtained by decomposing chrysotile or chrysotile-containing serpentine with an acid to substantially eliminate the influence of the asbestos on the living body. The curable composition preferably contains a surfactant and a thickener and / or a filler and / or a colorant. It preferably contains an air-hardening material and / or hydraulic material and a thickener. The composition preferably comprises 15-100% porous fibrous amorphous silica obtained by decomposing chrysotile or chrysotile-containing serpentine with an acid, 0-75% slaked lime, 0-3% thickener, and 0-10% pulp.

The invention relates to a house heat-insulation coating which comprises high-alumina cement, lime, fly ash, water glass and a foaming agent of aluminium powder. The high-alumina cement, lime, fly ash, and water glass with a weight ratio of 0.32-0.45:0.22-0.25:0.35-0.45:0.05 are mixed with 0.54-0.60 wt% of water, and the mixture is stirred in a reaction vessel to prepare viscous pasty fluid. The coating solidifies into solid at normal temperature after application for 10-24 hours. The coating can be coated on a newly-built wall directly without pointing; the coating can be used as a heat-insulation layer with a cement mortar protective layer covered outside, and has a service life being the same as a building; when the coating is used on an old building body, exterior wall coatings need to be polished completely before application of the coating of the invention. The coating has the advantages of no toxicity, no smell, no corrosion, no environment pollution, better heat insulation effect then polystyrene boards, and improved heat insulation performance by 30-50%. The preparation method of the coating can reduce the carbon dioxide discharge capacity. The coating and the preparation method of the invention have quite wide application prospects.
