Abstract
The sound-isolating and shock-resistant paint for car, building, ship and train is prepared with asphalt, high-molecular polymer, sodium petro-sulfonate, polybutylene-butadiene-imine, mica powder, calcium carbonate and solvent, and features excellent sound-isolating and shock-resistant effect, good anticorrosion and adhesion, and not embrittling at low temp.
Description
The present invention relates to a kind of coating of bituminous material, more particularly, is a kind of coating composition that can be used for the sound-insulation vibration-proof of aspects such as automobile, building, steamer, train.
Past, for the indoor sound-insulation vibration-proof of car body, asbestos packing is sneaked in pitch, the tar, obtain certain thickness sheet-like material after the drying, in the automotive paints process, it is layered on the indoor floor of car body, 140 ℃ of following fusions.Because the floor of car body is complex-shaped, rough and uneven in surface, it is very difficult all covering floor, therefore influence the sound-insulation vibration-proof performance of thin plate, and the antiseptic property of floor is also relatively poor.
In order to address the above problem, people begin to pay attention to the research sound-insulation vibration-proof paint, directly are coated on the car body, improve the sound-insulation vibration-proof effect.Japanese kokai publication sho 52-51428 proposes to contain the deadener of synthetic rubber or synthetic resins, but it is poor to connecting airtight property of body material.The spy opens clear 55-58262 and has proposed the sound-insulation vibration-proof paint be made up of packing materials such as styrene-butadiene rubber(SBR), pitch, acrylic copolymer and barium sulfate, aluminum chloride, natural Calucium Silicate powder, make solvent owing to use the xylol of aromatic hydrocarbons system, though its solvability is good, but toxicity is bigger, and is healthy harmful to the workmen.The spy opens the sound-insulation vibration-proof paint that clear 59-27955 proposes, be to be solvent with water, wilkinite is dispersed in the water and is made into bitumen emulsion as asphalt emulsifier, adopt synthetic rubber to make stopping composition as asphalt modifier agent and asbestos, glass fibre etc., this coating is without solvent, belong to the water and milk voltinism, be difficult for catching fire, but normal temperature is difficult for drying down.It is to be that main sound-proof material, dimethylbenzene or water are solvent with kiln ash that the spy opens sound-insulation vibration-proof paint that clear 61-19670 proposes, and dimethylbenzene is poisonous, and HUMAN HEALTH is harmful to, water as solvent normal temperature is difficult for dry down, the forced drying more than 170 ℃ of need heating was both consumed energy like this, and was dangerous again.
The objective of the invention is to overcome the shortcoming of prior art, provide a kind of and have that good sound-insulation vibration-proof effect, antiseptic property and adhesion property are good, low temperature not embrittlement, strong shock resistance, smear sound-insulation vibration-proof paint easily.
Coating of the present invention is made up of tackiness agent, thickening stabilizer, tensio-active agent, solid filler and organic solvent, and it is as follows that it forms content (in coating 100%, heavy %):
Tackiness agent 12～30%, preferably 14～23%;
Thickening stabilizer 1～8%, preferably 2.5～5.5%;
Tensio-active agent 2.5～8%, preferably 4～6%;
Solid weighting agent 35～60%, preferably 38～52%;
Organic solvent 18～35%, preferably 22～32%;
Water 0.3～1.0%, preferably 0.4～0.7%.
Described tackiness agent is to be mixed by the macromolecular compound of pitch with certain polymerization degree, and its ratio of mixture is a pitch: high molecular polymer=90～99: 10～1; Described pitch is that penetration degree is 41～120, softening temperature is 25～45 ℃ road bitumen or penetration degree is 5～40, softening temperature is 60～110 ℃ building asphalt, or both mixtures.If both mix, its ratio of mixture is a road bitumen: building asphalt=60～80: 40～20, and they are main caking agents of coating, both ratios are excessive, coating deliquescing, sound-insulation vibration-proof effect descend, so the best ratio of road bitumen and building asphalt is 65～75: 35～25.Described macromolecular compound comprises liquid polybutadiene, polyisobutene, styrene-butadiene rubber(SBR), ethylene-propylene copolymer, polybutadiene rubber, their molecular weight is 500～60000, preferably 1000～30000, it mainly acts on is the problem that solves coating low temperature embrittlement, its adding makes the coating flexible, but add-on too much can make the sprayability variation of coating.
Described thickening stabilizer is organobentonite or inorganic bentonite, or both mixtures, if the mixing of organobentonite and inorganic bentonite, its ratio of mixture is 1: 1.3～2.0.Add this thickening stabilizer and mainly be the viscosity that improves coating, improve package stability, if do not add or add thickening stabilizer less, coating is thinning, and very fast layering.
Described tensio-active agent is anion surfactant or nonionogenic tenside, or both mix, if both mix, its ratio of mixture is an anion surfactant: nonionogenic tenside=1: 1～1.6; Described anion surfactant comprises petroleum sodium sulfonate, synthetic sodium sulfonate, calcium mahogany sulfonate, calcium alkylbenzenesulfonate, barium mahogany sulfonate, synthetic barium sulfonate; Described ionic surfactant pack is drawn together the condenses of condenses, higher alcohols and the oxyethane of diamide under the polyisobutene, sorbyl alcohol and oleic reactant, alkylphenol and oxyethane.Tensio-active agent can improve the non-corrosibility and the sprayability of coating.
Described solid filler is to be selected from mica powder, lime carbonate, kaolin, asbestos powder, graphite, the aluminium silicate powder one or both, and it mainly acts on is sound-insulation vibration-proof, and add-on is very few, dope viscosity diminishes, the sound-insulation vibration-proof weak effect, add-on is excessive, the operability variation.If above-mentioned stopping composition mica powder and be selected from remaining any mixing, its ratio of mixture is 1～2: 1.
Described organic solvent is 120
#Industrial naptha, straight-run spirit, platformate raffinate, straight-run spirit and the final boiling point of raffinating oil can not be greater than 150 ℃, and its effect is that fluxed asphalt becomes solution, be convenient to each component uniform mixing, dosage is too much, and coating easily runs off on coated steel plates, dosage is very few, operability and sprayability variation.
The composition of sound-insulation vibration-proof paint of the present invention prepares as follows:
(1) preparation bituminous solution: earlier tensio-active agent is added in the reactor, add road bitumen and building asphalt more in proportion, add organic solvent 30～40 heavy % (in bituminous solution 100 heavy %) then, stir, be warming up to more than 80 ℃ and reflux, after treating all dissolvings, be cooled to room temperature, add high molecular polymer at last, stir evenly stand-by.
(2) with after stirring evenly in (1) step asphaltic liquid, residue organic solvent and the water adding reactor, add thickening stabilizer and solid filler more by a certain percentage, at room temperature stir evenly and promptly get desired product.
Major advantage of the present invention: owing to find suitable component and proportioning, make the good combination property of this coating.For example adopt pitch and high molecular polymer modification agent, make clagging good, low temperature is embrittlement not, can impact by anti-silt; Employing mica powder etc. is made stopping composition, and the coating rate of fall-off is big, and soundproof effect is good; Make thickening stabilizer with wilkinite, product changes little, not stratified in viscosity more than 90 days; Adopt different tensio-active agent and rust-preventive agent, make the antiseptic power of coating strong, atomization is good, is sprayed on the steel plate more smooth; Because the present invention does not use aromatic hydroxy compound to make solvent, the toxicity of coating is less.Coating of the present invention can be used for the vibrationproof sound insulation of aspects such as automobile, building, steamer, train.
