Abstract
The invention discloses a sound-absorbing coating for an interior wall, and relates to the technical field of coating building materials. A production method for the sound-absorbing coating comprises the following steps of: taking cornstarch, kaolin, light-calcium powder, talcum powder, OK powder, cellulose, redispersible polymer powder and glass beads as raw materials according to specified proportioning ratio; and mixing, stirring, filtering and drying in specified conditions to obtain the finished product. The product disclosed by the invention has the advantages of being good in sound-absorbing performance, energy-saving and environmental-friendly, low in cost, and convenient to transport and use.
Description
Technical field
The present invention relates to the coating building materials technology field, particularly relate to a kind of interior wall sound deadening coating and production method thereof.
Background technology
Along with the development of society, the noise in the environment is increasing, has a strong impact on people's physical and mental health, and general interior wall coating does not have sound absorption function, can not be with helping solve noise problem.And there is defective in existing sound deadening coating at aspects such as sound-absorbing effect, production cost, environmental protection.
The chemical composition that the present invention relates to is analyzed as follows:
Cornstarch: i.e. the yam starch of Shenging is generally starch commonly used of present family, is after potato is ground, and rubs and washes, precipitates and make.The viscosity foot, the quality exquisiteness, look pure white, and gloss is better than green starch, but water-absorbent is poor.Adding water and meet heat and can condense into transparent thickly, is by physics or chemical process, with the product that obtains behind the original starch denaturalization.Cornstarch mainly contains following several form: thickening material, gelifying agent, emulsion stabilizer, modifying agent, water-holding agent, excipient, weighting agent, raising agent etc. in Application in Food Industry.
Kaolin: the pure kaolin of matter have whiteness height, soft, the easy dispersion suspension of matter in water, good plasticity-and high cohesiveness, excellent electric insulation performance; Have good antiacid dissolubility, very low cation exchange capacity, physico-chemical property such as resistivity against fire preferably.Therefore kaolin has become tens necessary raw mineral materialss of industry such as papermaking, pottery, rubber, chemical industry, coating, medicine and national defence.Kaolin is very extensive in application in papermaking industry.Mainly contain two fields, one is the filler that uses in papermaking (or claiming to copy paper) process, and another is the pigment that uses in the surface coated process.
Light calcium carbonate powder: claim light calcium carbonate again, be raw material sections such as Wingdale to be burnt generate lime (main component is calcium oxide) and carbonic acid gas, add water digestion lime again and generate milk of lime (main component is calcium hydroxide), and then feeding carbonic acid gas carbonization milk of lime generates precipitation of calcium carbonate, make finally by dehydration, drying and pulverizing, perhaps carry out replacement(metathesis)reaction with yellow soda ash and calcium chloride earlier and generate precipitation of calcium carbonate, make through dehydration, drying and pulverizing then.Light calcium carbonate powder, be generally white, nontoxic, odorless, nonirritant, react with all strong acid, light calcium carbonate fine particles, surface are more coarse, specific surface area is big, therefore oil-absorption(number) is higher, have the small product size of increasing, reduce cost, improve processing characteristics (as regulating viscosity, rheological property, curability), improve dimensional stability, reinforcement or half reinforcement, improve printing performance, improve physicals effects such as (as thermotolerance, extinction, wear resistance, flame retardant resistance, whiteness, glossiness).
Talcum powder: be the powder of white or off-white color, fine, no grittiness, hand has been touched greasy feeling, and odorless is tasteless, does not all dissolve in water, the acid of rare ore deposit or rare alkali hydroxide solution.Can do medicinal.Good physics, chemical propertys such as having oilness, anti-stick, help that stream, resistivity against fire, resistance to acid, insulativity, fusing point height, chemical torpescence, opacifying power are good, softness, good luster, adsorptive power are strong.
The OK powder: pure white, viscosity good, this product is used for modification 106,803 coating can the instead of part Cornstarch, zinc sulfide white, and reduces PVA consumption 10%, reduces coating cost 40% approximately.As inorganic exterior coating, porcelain-imitated coating, toughened paint, emulsion paint etc., have effects such as water tolerance, washable wiping, ageing resistance, slipperiness, nondiscoloration, particularly washable wiping can be above 1000 times, and have fabulous frost resistance (subzero 20 ℃ are not freezed), and can construct at wet wall.The OK powder has solved coating that grey calcium powder is done easily precipitation and the coarse defective of coating, during for the production of dry powder paint, can make dry powder paint fluffy, fine and smooth, and speed of application and effect are obviously improved.
Re-dispersible glue powder: be mainly used in external wall outer insulation haftplatte, plastering mortar, ceramic tile bonding, gravity flowing levelling mortar, concrete mortar, dried powder boundary agent, jointing agent.This product configuration mortar has high pressure to be cut, and slip resistance has and the weather resistance of concrete with the life-span, do not come off, can eliminate crackle for the lightweight body of wall, comprise wall on the wet plate, the crackle that door and window mouth stress crack and mountain range phase cause inadequately is a kind of brand-new high-tech product.
Glass bead: be a kind of acid glassiness lava mineral substance (pitchstone ore in sand form); be processed to form the vitreous sealing of the Duo Kong ﹑ of Nei portion surface through special technology processing and production technique; being the thin footpath of spherule particle, is a kind of high performance novel inorganic light heat-insulating material that has.Because its surperficial vitreous forms certain granule strength, physicochemical property is very stable, and ageing-resistant weathering resistance is strong, has excellent thermal insulation, fire prevention, sound absorption qualities.The glass bead water-intake rate is low, easily disperses, and as aglite, can improve the easy mobility of thermal insulation mortar and anti-certainly intensity with glass bead, reduces the material contracts rate, improves the thermal insulation mortar over-all properties, reduces comprehensive production cost.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of interior wall sound deadening coating and production method thereof are provided, this interior wall sound deadening coating sound absorption qualities is good, energy-conserving and environment-protective, low, the transportation and easy to use of cost.
