Abstract
The invention discloses an organosilicon-modified polyvinyl butyral coil coating comprising the following components by mass percentage: 60% to 70% of alcohol solution of polyvinyl butyral, 10% to 20% of phenyl-trimethoxysilane, 10% to 20% of phenyl-methyl-dimethoxysilane, 1% to 8% of distilled water and 0.5% to 1% of phosphoric acid, wherein the organosilicon-modified polyvinyl butyral coil coating is prepared through the sol-gel reaction. The organosilicon-modified polyvinyl butyral coil coating of the invention has the characteristics of high strength, good toughness, low curing temperature and environment friendliness.
Description
Technical field
The present invention relates to technical field of coatings, relate to a kind of coil coating, more particularly, relate to a kind of organosilicon-modified polyvinyl butyral coil coating.
Background technology
Coil coating puts goods on the market as far back as the U.S. the thirties in 20th century, and development after World War II is very fast, independent formation one big coating system from industrial coating.There is the VOC discharging in traditional coil coating, needs hot setting, sacrifices hardness to increase flexible defective.Carried out a large amount of work around these Study of Defects personnel, some achievements have been obtained, a kind of coil coating is disclosed as patent CN200910029798.1, its solidification value is reduced to 180～190 ℃ by original 224～241 ℃, but such solidification value is still than higher, and energy consumption is still bigger.And patent CN200880003471.0 discloses a kind of excellent flexible coil coating that makes up with hardness that shows, but involved solvent all is the compound that toluene and dimethylbenzene etc. contain phenyl ring in this patent, is unfavorable for environmental protection.
Summary of the invention
Technical problem: the objective of the invention is for overcome existing coil coating exist VOC discharging, solidification value higher, sacrifice hardness to increase flexible defective, solve the relevant technologies problem.A kind of organosilicon-modified polyvinyl butyral coil coating is provided.
Technical scheme: in order to achieve the above object, the present invention is by selecting for use polyvinyl butyral acetal as main filmogen, and adds phenyltrimethoxysila,e, phenyl methyl dimethoxy silane, distilled water, phosphoric acid (85%) make novel coiled material coating by sol gel reaction in system.
The technical scheme that technical solution problem of the present invention is adopted is:
A kind of organosilicon-modified polyvinyl butyral coil coating, alcoholic solution by the component polyvinyl butyral acetal is 60～70% by mass percentage, phenyltrimethoxysila,e is 10～20%, phenyl methyl dimethoxy silane is 10～20%, distilled water is 1～8%, and phosphoric acid is 0.5～1% composition.
The alcoholic solution of above-mentioned polyvinyl butyral acetal be solvent and polyvinyl butyral acetal by quality 60:40 proportioning mixed dissolution, wherein said solvent is a dehydrated alcohol.
The preparation of organosilicon-modified polyvinyl butyral coil coating: at first alcoholic solution, phenyltrimethoxysila,e, phenyl methyl dimethoxy silane, the distilled water of polyvinyl butyral acetal are put in the there-necked flask of being furnished with heating unit according to a certain ratio, when treating that system temperature is stabilized in 50 ℃, dropwise drip phosphoric acid and finish until reaction in system, the reaction times is 5 hours.
Beneficial effect: the advantage and the beneficial effect of organosilicon-modified polyvinyl butyral coil coating of the present invention mainly are:
Because the molecular structure of polyvinyl butyral acetal and efficient film-forming properties provide excellent sticking power and snappiness for coating; The existence of phenyltrimethoxysila,e can further increase the snappiness and the weathering resistance of coating; The final sticking power of coating is 0～1 grade, and hardness is 4H, and 120～180 ° of coatings of base material turnover do not ftracture, and is promptly curable under 50～80 ℃; Of paramount importance is not exist in the whole system the poisonous and hazardous organic gas discharging of environment.
