Abstract
The present invention belongs to a fire-retardant ceiling with antistatic properties. At present, static prevention is considered more and more in the rooms of computers and microelectronic techniques and in the enterprises of motion picture film manufacture, military industry, aerospace, etc. However, the existing anti-static materials used indoors has few anti-static material varieties, poor effect and relatively complicated manufacturing technique. The fire-retardant ceiling with antistatic properties of the present invention is made of sand texture materials which are composed of antistatic agents, such as phenyl-propyl emulsion, hydroxymethyl cellulose, an amide antistatic agent, ethylene alcohol, polyacrylic acid sodium salt, an ammonium polymethacrylate saline solution, pure water, silica sand, titanium white powder, color paste, etc. The present invention can be widely applied to ceilings which need preventing static for indoor space.
Description
The present invention relates to a kind of ceiling with antistatic property, its surface is sand wall shape, and is nonflammable.
At present, in, cinefilm manufacturing indoor, bioengineering, Aero-Space and the military enterprise, static electricity prevention and curing is more and more caused people's attention at computer and microelectric technique.In the material field of static electricity prevention and curing, appearance such as antistatic floor and antistatic wall covering are arranged successively.As the flat 2-122928 of Japan Patent " anti-charged floor " is exactly wherein a kind of, and it is made up of the top layer conductive layer that to be the mixed electroconductive zinc oxide of non-halogen based polymer, lower floor or internal layer constitute by carbon black or graphite and non-halogen based polymer.The clear 58-5374 of Japan Patent " anlistatig wall surface material " and for example, this be a kind of with adsorption of metal ions on tacryl, be processed into the conductive fiber material of suitable length, with this fibrous material be bonded on the paper substrate after water, synthetic resin mix, dry back jointing material becomes the needle-like burr, becomes the wall surface material of removing static.
The objective of the invention is for a kind of ceiling with antistatic property is provided, and have flame retardancy and the surface is ornamental sand wall shape.
As substrate, the sand wall shape material that the substrate surface spraying contains compositions such as base-material, plasticizing agent, antistatic additive, coalescents, dispersing agent, thickener, solvent, filler, pigment and colorant constitutes by gypsum plank, TK plate, mineral wool board or the pearlite slab of flame retardancy in the present invention.
Fire-retardant sand-wall shaped antistatic ceiling of the present invention is made of two parts: the substrate of anlistatig sand wall shape material and flame retardancy.Sand wall shape material is that base-material, CMC are that plasticizing agent, HOA amide-type material are that antistatic additive, ethylene glycol are that coalescents, polyacrylic acid sodium salt are that dispersing agent, ammonium polymethacrylate saline solution are that the pure water of thickener, electrical conductivity＜100 Ω is that solvent, 30～100 purpose silica sands are that filler, titanium dioxide are pigment by benzene-acrylic emulsion, and to mix mill base be colorant, and the according to the form below proportioning is formed pastes.
| Title | Ratio (%) | Title | Ratio (%) |
| Benzene-acrylic emulsion | 20.0～35.0 | Poly-methyl-prop diluted acid ammonium salt aqueous solution | 1.0～4.0 |
| CMC | 2.0～4.0 | Pure water (electrical conductivity＜100 Ω) | 5.8～0.9 |
| The amide-type antistatic additive | 0.5～5.0 | Silica sand (30～100 order) | 55.0～38.0 |
| Ethylene glycol | 5.0～1.0 | Titanium dioxide | 7.6～10.0 |
| Polyacrylic acid sodium salt | 3.0～0.1 | Mill base | 0.1～2.0 |
To evenly be sprayed at by the pastes that said ratio is made on gypsum plank, TK plate, mineral wool board or the pearlite slab of difficult combustion,, can become fire-retardant sand-wall shaped antistatic ceiling through dry 26 hours of normal temperature.
Above-mentioned antistatic ceiling is through measuring its surface insulation resistance≤10
9Ω, and have good electrostatic discharged, leaking performance, but also have characteristics such as difficult combustion, strong adhesion.
Embodiment:
Be the surface of substrate at TK plate (being asbestos cement sheet), the sand wall shape material that spraying is made up of the following table proportioning.
| Title | Ratio (%) | Title | Ratio (%) |
| Benzene-acrylic emulsion | 28.7 | Poly-methyl-prop diluted acid ammonium salt aqueous solution | 2.0 |
| CMC | 4.0 | Pure water (electrical conductivity＜100 Ω) | 1.9 |
| The amide-type antistatic additive | 1.0 | Silica sand (30～100 order) | 50.3 |
| Ethylene glycol | 2.0 | Titanium dioxide | 9.5 |
| Polyacrylic acid sodium salt | 0.1 | Mill base | 0.5 |
The pastes of making according to the above ratio is sprayed on the substrate, through normal temperature after dry 26 hours, just become awkward combustion, profile is the ceiling with antistatic property of sand wall shape.
