Description
The invention belongs to architectural decoration material field, be specifically related to a kind of light silencing and refractory mineral decoration board and working method thereof.
Generally adopt plasterboard and stone(mine)cotton plate as indoor furred ceiling or adherent decoration at present both at home and abroad.But plasterboard unit weight is big, sound absorbing coefficient is little, the moisture-sensitive distortion, and contain the shortcomings such as fiber that are unfavorable for HUMAN HEALTH; Stone(mine)cotton plate generally all adopts organic binder bond to process, and needs top coat, and fire resistance period is short, and poisonous in the course of processing, flavor, contaminate environment are arranged, harmful HUMAN HEALTH is unfavorable for that the workman operates.U.S. Pat 3778281 discloses a kind ofly makes light-weight refractory sheet material and working method thereof by materials such as vermiculite, clay and borates.The weak point of this sheet material is a processed complex, must roasting under 1300 temperature condition, and hot pressing under 400 temperature condition.
The object of the invention provides a kind of fibrous magnesium silicate that do not contain, and fire resistance period is long, and sound absorbing coefficient is big, and unit weight is little, without the decorative sheet and the working method thereof of high-temperature molding.
Technical scheme of the present invention is: the raw material of this decorative sheet consists of (weight percent): 100～300 parts of expanded vermiculites, 100～200 parts of inorganic adhesives, 5～20 parts of additives, 5～15 parts of water-resisting agents.The consisting of of inorganic adhesive (parts by weight): 1～20 part of potassium silicate solution, 1～6 part of silicon sol, 0～0.5 part of superpolymer, 0.1～0.5 part in water.The consisting of of additive (weight percent): 1～5 part of potassium primary phosphate, 0～10 part of Calcium Chloride Powder Anhydrous, 2～50 parts of semi-hydrated gypsums, 0.5～2 part of potassium silicofluoride (or sodium).The consisting of of water-resisting agent (weight percent): 0.1～2 part of hydrogeneous methyl-silicone oil emulsion, 0.1～2 part of hydroxymethyl silicone oil emulsion.
The working method of this decorative sheet is: with 100～300 parts of granularities is 80～100 purpose expanded vermiculites, and 100～200 portions of inorganic adhesives stir after 5～20 parts of additives and 5～15 parts of water-resisting agents mix; With the mixture mould of packing into; Use the oil press extrusion forming down at normal temperature (room temperature); The demoulding; The moulding product are carried out getting product after the gradient increased temperature segmentation maintenance drying.
The preparation method of inorganic adhesive is: with 1～20 part of potassium silicate solution, 1～6 part of silicon sol, 0～0.5 part of superpolymer and 0.1～0.5 part of water mixing post-heating stir to specific viscosity be 40～60 seconds.The preparation method of additive is: with 1～5 part of potassium primary phosphate, and 0～10 part of Calcium Chloride Powder Anhydrous, 2～50 parts of semi-hydrated gypsums, 0.5～2 part of potassium silicofluoride (or sodium) mixes, and grinds evenly on ball mill.The preparation method of water-resisting agent is: with 0.1～2 part of hydrogeneous methyl-silicone oil emulsion, stir after 0.1～2 part of hydroxymethyl silicone oil emulsion mixes.Gradient increased temperature segmentation maintenance drying is that advanced trip temperature is 40～60 ℃ of maintenance dryings under the condition, and carrying out temperature again is 80～100 ℃ of maintenance dryings under the condition.
Advantage of the present invention is: product has lightweight, sound-absorbing and fireproof characteristics; Simple and convenient processing method, nontoxic in the production process, harmless, pollution-free; Adopt normal temperature pressurization, gradient increased temperature segmentation maintenance drying process, improved product qualified rate and production efficiency greatly, reduced production cost.
