Abstract
The present invention relates to paint and a preparation method. The method mainly solves the problems of poor endurance, high price, etc., in existing coal tar series paint. The paint comprises high temperature coal tar, lead monoxide or/and manganese acetate, cement, castor oil, tung oil, talcum powder or/and barium sulfate. The preparation method of the present invention comprises the following steps: firstly, the high temperature coal tar is preprocessed to remove surface water; then each component is weighed according to a mixture ratio; the castor oil, the tung oil and the barium sulfate are added to heated high temperature coal tar and stirred evenly to produce component A; the lead monoxide, the manganese acetate, the cement and the talcum powder are mixed evenly to produce component B; and finally, the component A and the component B are evenly mixed with xylene solvent or/and 200 <#> gasoline to produce the paint.
Description
The present invention relates to a kind of coating and preparation method thereof, specifically a kind of is the protective system and preparation method thereof of matrix with coal tar.
Directly coal tar is used as protective system, though have economic competent advantage, coating is done bath time length, is had shortcomings such as light fugitive, non-heatproof; Existing coal tar coating series all is to add organic materialss such as Resins, epoxy, urethane resin to carry out modification in coal tar, though improved over-all properties, endurance quality is relatively poor, especially price higher, be unfavorable for being extensive use of.
The purpose of this invention is to provide that a kind of water resisting property is good, cohesive force is strong, fast light, durable, can control coating time of drying and low inorganic modified paint of coal tar and the preparation method of cost.
The matrix of coating of the present invention is coal-tar heavy oil, this coating also contains drying promoter plumbous oxide or/and manganese acetate, water-retaining agent cement, softening agent Viscotrol C, light-shielding agent tung oil, filler talcum powder or/and barium sulfate and solvent, the weight percent of this coating is:
Coal-tar heavy oil 50-75
Plumbous oxide 0.5-2.5
Manganese acetate 0.2-1.0
Cement 5-8
Viscotrol C 3-8
Tung oil 0.3-1
Talcum powder 8-10
Barium sulfate 8-14
The solvent surplus.
Above-mentioned drying promoter also can add Manganse Dioxide, and water-retaining agent also can add the refined lime powder, and light-shielding agent also can add glycerine, and filler also can add manganous carbonate.
Said components also can increase thickening material kaolin or potter's clay.
The present invention can realize by following mode:
Earlier high temperature tar is heated while stirring and after 80 ℃-95 ℃, left standstill 24 hours, remove surface water then, and operate by following step:
A, take by weighing above-mentioned pretreated coal-tar heavy oil and heat to about 50 ℃ by ratio of components,
B, take by weighing Viscotrol C, tung oil and barium sulfate, and drop into while stirring among the A by ratio of components,
C, postcooling to the room temperature that stirs are packed, and promptly make the first group,
D, by ratio of components take by weighing plumbous oxide, manganese acetate, cement and talcum powder, mix the back pack with poly-bag, promptly make the second group,
E, will the second group drop in the first group and the back that stirs adds solvent xylene or/and 200# gasoline is promptly made inorganic modified paint of coal tar after stirring.
Still contain a spot of water (about 3%) through pretreated coal-tar heavy oil, adding cement promptly is in order to remove this portion water as water-retaining agent, and cement also has the hardness of paint film of raising and fast to light effect simultaneously.
Weigh the rot-resistant works for needs, then need apply thick slurry lacquer (promptly thicker coating), can in first group, second group and solvent, add thickening material and get final product.
If only make first group and second group, then, do not need to adopt the encloses container packing owing to all do not contain volatile matter in first and second liang of groups, reduced production cost, and preservation period can reach 3 years, only need in use first group, second group and solvent are evenly got final product.
If envrionment temperature, then needs suitably heating first group below 25 ℃, if envrionment temperature more than 25 ℃, then needs suitably to reduce second group consumption, the consumption by adjusting the second group is the rate of drying of may command coating also during use.
Raw material of the present invention is cheap and easy to get, production technique is simple, and product cost is low, has a water resisting property long advantage of strong, anticorrosion cycle of cohesive force.What be widely used in that steel such as chemical industry, water conservancy project, mine and transportation tie is anticorrosion, under water or assign more than 15 years, in atmosphere, reach more than 10 years about 1 yuan of every square metre of expense, every square metre is expended less than 0.1 yuan (general impregnating material is all in 2.5-5 unit) in year, economical and practical.
Embodiment:
A, take by weighing pretreated coal-tar heavy oil 75kg and heat to about 50 ℃,
B, take by weighing Viscotrol C 3kg, tung oil 0.3kg and barium sulfate 8kg, drop into while stirring among the A,
C, postcooling to the room temperature that stirs are packed, and promptly make the first group,
D, take by weighing plumbous oxide 0.5kg, manganese acetate 0.2kg, cement 5kg and talcum powder 8kg, mix the back and pack, promptly make the second group with poly-bag,
E, will the second group drop in the first group and the back that stirs adds dimethylbenzene 10kg or/and 200# gasoline 10kg promptly makes inorganic modified paint of coal tar after stirring.
