Abstract
The invention relates to a bismaleimide-containing waterproof acid and alkali resistant paint, which is composed of the following constituents according to parts by weight: 30-40 parts of bismaleimide, 30-40 parts of urea-formaldehyde resin, 10-20 parts of polystyrene resin, 10-20 parts of polyethylene glycol, 10-20 parts of calcium silicate, 5-10 parts of asbestos, 5-10 parts of glass fiber, 5-10 parts of monochloro acetic acid, 5-10 parts of feldspar powder and 50-70 parts of n-butyl alcohol. The prepared bismaleimide-containing paint has better waterproof property and acid and alkali resistance.
Description
Technical field
The present invention relates to a kind of waterproof acid and alkali-resistance coating, particularly relate to a kind of waterproof acid and alkali-resistance coating that contains bismaleimides.
Background technology
At present, society is being showing improvement or progress day by day, and all trades and professions have also obtained significant progress thereupon.In this process, the client is more and more widely to the demand of coating, and the specification of quality to coating also is more and more higher simultaneously.In the professional domain that relates to waterproof and acid and alkali-resistance coating, as fields such as some households, building, decorations, and the field that needs acid and alkali-resistance, requirement to waterproof acid and alkali-resistance type coating also is to increase thereupon, the coating type that has at present waterproof and acid and alkali-resistance effect on the market simultaneously is less, and therefore developing a kind of coating that has excellent waterproofness and resistance to acids and bases simultaneously has very wide ample scope for abilities.
Summary of the invention
The technical problem that solves: the relatively poor problem of conventional coating water-acid resistance effect.
Technical scheme: the present invention is a kind of waterproof acid and alkali-resistance coating that contains bismaleimides, it is made up of according to weight ratio following composition: 30～40 parts of bismaleimidess, 30～40 parts of urea-formaldehyde resins, 10～20 parts of polystyrene resins, 10～20 parts of polyoxyethylene glycol, 10～20 parts of Calucium Silicate powder, 5～10 parts in asbestos, 5～10 parts in glass fibre, 5～10 parts of Monochloro Acetic Acids, 5～10 parts of Feldspar Powders, 50～70 parts of propyl carbinols.Constantly stir by various compositions are dropped in the reactor, can obtain to have the coating of good waterproof acid and alkali-resistance effect after waiting to stir.
Beneficial effect: after preparing the waterproof acid and alkali-resistance coating that contains bismaleimides, its water-repellancy and resistance to acids and bases are tested, after coating evenly is sprayed on the tinplate surface, sample is put into water carry out waterproof test, the waterproof test duration is 40～50 days, and other gets the even tinplate sample that has sprayed coating and carries out the acid and alkali-resistance experiment, and alkali lye is the sodium hydroxide solution of 2mol/L, acid solution is the phosphoric acid solution of 2mol/L, and the time is 10～20 days.The result shows the coating that contains bismaleimides that the present invention the makes foaming phenomenon that do not ftracture in 40～50 days, has excellent waterproofness, under the phosphoric acid solution of the sodium hydroxide solution of 2mol/L and 2mol/L, do not have unusual foaming phenomenon in 10～20 days in addition yet, have good acid and alkali-resistance effect.
