Abstract
A process for preparing quickly dried anticorrosion paint with natural asphalt includes the steps of respectively dissolving resin and asphalt in solvent, mixing and stirring. Obtained paint features higher mechanical strength and adhesion (its toughness and adhesion can reach class I), high hardness (3H), short drying time (1 hr for surface or 15 hr for whole), and high resistance to acid, alkali and weather.
Description
The present invention relates to the method that a kind of rock asphalt prepares fast dried antifouling paste
The preparation antifouling paste utilizes petroleum pitch or coal tar pitch to pass through rosin modified phenolic resin mostly at present, bituminous epoxy, siccative oil, No. 200 solvent oils of interpolation or No. 200 coal tar, dimethylbenzene is made, and product is used for waterproof, protection against the tide and antirust at the common metal external coating mostly.Its surface drying time is less than 2 hours, do solid work less than 24 hours, but product ubiquity bad mechanical property, particularly No. 200 coal-tar solvents of coal-tar pitch needs and heavy benzene are made solvent, bigger in its operation to workmen's toxic, add Resins, epoxy, though have chemical resistance preferably, but be two components, and its time of drying is slower, the cost height, and the grown place of siccative oil is limited simultaneously, for remote districts, the transportation line length, cost strengthens, and has limited application greatly, be vulnerable to Temperature Influence for coal-tar pitch, use in cold or high temperature area, quality product is subjected to very big influence, therefore uses to be restricted.
The production technique of bituminous varnish has heat refining method and cold method for making
The heat refining method is earlier with resin, and pitch is packed in the pot, and firing up dissolves heat refining, and temperature rises to 250-290 ℃, reduce to certain temperature after, add solvent cut and leave standstill, filter, temperature of reaction is higher, easily makes asphalt coking.The easy coking of this pitch.
Cold method for making is earlier solvent to be squeezed in the jar, is warming up to about 100 ℃, adds bituminous resins and siccative etc. again, keeps temperature, with its whole dissolvings, then leaves standstill and filters and packages, and this method is more stable than heat refining method, but the reaction times is longer.
More than two kinds of methods resin is pulverized in advance, and easily tie fast blocking pipe and equipment, produce discontinuous weakness.
The present invention develops the method for the fast dried antifouling paste of a kind of rock asphalt (pitch earth) preparation through a large amount of tests, and this method adopts rock asphalt, its quality is pure, the softening temperature height, oil soluble is good, the equal solubilized of most of solvents, film forming is smooth, be ideal system raw materials for varnish, adopt modified phenolic resins to improve the mechanical property of bituminous varnish simultaneously, make it have good hardness, add solvent then, make rock asphalt and modified resin that solvability preferably be arranged in this solvent, add siccative, anti puffing agent and filler can improve the physical strength and the sticking power of lacquer, have and be difficult for being gathered into fast characteristics, this paint vehicle solvability is good, and sticking power and snappiness all reach 1 grade, and hardness reaches 38, surface drying time was less than 1 hour, do solid work less than 15 hours, simultaneously, the hydrochloric acid of this lacquer ability 10%, 10% sodium hydroxide, 3% sodium-chlor.Constant product quality is not subjected to the weather Temperature Influence, and use range is wider, and technology is simple, and cost is lower.
The object of the invention is, the method of the fast dried antifouling paste of employing rock asphalt (pitch earth) preparation of development, be to adopt integrated process production, promptly adopt resin and pitch to use dissolution with solvents respectively, mix then and transfer sticking method, having overcome the heat refining method needs comparatively high temps easily to make asphalt coking, the weakness that cold method for making easily makes pipeline and equipment stop up, and it is good to have a solubility property, can produce continuously and carry out, and has saved characteristics such as the energy.
The method of the fast dried antifouling paste of employing rock asphalt of the present invention (pitch earth) preparation, be to adopt resin and pitch to use dissolution with solvents respectively, mix the sticking method of transferring then, this method at first be with rock asphalt (pitch earth) add siccative, anti puffing agent stir, heat, dissolve, adding dissolution with solvents, promptly get product I (stand-by); Next is rosin modified phenolic resin to be added dissolution with solvents promptly get product II (stand-by); Then product I and product II are mixed, add filler, grind, transfer sticking getting product; Wherein siccative is a kind of in manganese naphthenate, sylvic acid manganese soap, lead naphthenate, plumbous oxide, sylvic acid lead soap, the rosin zinc soap or two kinds, anti puffing agent is a sylvic acid calcium, filler is a superfine silicon dioxide, light calcium carbonate, ultra-fine diabase flour, wollastonite powder, talcum powder; Solvent be a kind of straight-chain paraffin (boiling point 120-200 ℃) with benzene,toluene,xylene in one or both or three kinds mix in 1: the mixture of 1-200 ratio preparation; Each component proportioning in this method is (weight percent) rock asphalt 10-35%, rosin modified phenolic resin 1-10%, filler 30-5%, siccative, anti puffing agent 0.5-5%, solvent 33.5-70%.
Embodiment 1, (weight percent)
