Abstract
The invention discloses a freezing disaster resistant power grid coating which is prepared by a sol-gel reaction from the following components in percentage by weight: 60-70% of alcoholic polyvinyl butyral solution, 10-20% of organic silicon prepolymer, 10-20% of ethyl orthosilicate, 1-8% of distilled water and 0.5-1% of phosphoric acid. The freezing disaster resistant power grid coating of the invention has characteristics of high hydrophobicity, high adhesion, and high flexibility.
Description
Technical field
The present invention relates to technical field of coatings, relate in particular to a kind of coating of freezing disaster resistant power grid.
Background technology
At the beginning of 2008, rare since the establishment of the nation low temperature, sleet and freezing weather have appearred in most of area of southern china and east, the Northwest, cause the electrical network well damage, have caused very big influence to people's lives.And cause the most direct reason of electric network freezing disaster is exactly that moisture content is met low-temperature curing Cheng Bing attached to substrate surface.The hydrophobic interface coating (patent CN200810228995) that present researchist has developed a kind of south electric network freezing disaster preventing solves the problem of electric wire surface attachment moisture content, but all there is defective in this coating in sticking power, flexibility.
Summary of the invention
Technical problem: the objective of the invention is to have defective in sticking power, flexibility, and the coating material of a kind of strong adhesion, freezing disaster resistant power grid that snappiness is good is provided for the coating that solves existing freezing disaster resistant power grid.
Technical scheme: to achieve these goals, the technical scheme that technical solution problem of the present invention is adopted is:
A kind of freezing disaster resistant power grid coating, content is by component by mass percentage: the alcoholic solution of polyvinyl butyral acetal is 60～70%, and the organosilicon performed polymer is 10～20%, and tetraethoxy is: 10～20%, distilled water is 1～8%, and phosphoric acid is 0.5～1% composition.
Wherein, the solvent of the alcoholic solution of described polyvinyl butyral acetal is to be made of propyl carbinol and dehydrated alcohol, and the volume ratio of the two is 4: 1; The mass percent of polyvinyl butyral acetal in this alcoholic solution is 50%.
Described organosilicon performed polymer is meant the polymkeric substance that structure is following:
Preparation method: at first alcoholic solution, organosilicon performed polymer, tetraethoxy, 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 molecular structure of polyvinyl butyral acetal and efficient film-forming properties provide excellent sticking power and snappiness for coating among the present invention; The existence of organosilicon performed polymer can further increase the snappiness and the hydrophobic nature of coating.The final sticking power of coating is 0～2 grade, and 120～180 ° of coatings of base material turnover do not ftracture, and it is 100～140 ° that water at normal temperature drips contact angle.And the catalyzer of using in the sol gel reaction is phosphoric acid, and the hydrochloric acid that can use as tradition etc. does not produce corrosive nature to metal base.
