Abstract
The invention relates to a kind of new-type monocomponent anticorrosive paint and its manufacturing method. The anticorrosive paint comprises solvent, film forming resin, auxiliary, and pigment, filler; and among which, the main component in film forming resin is modified polystyrene resin that manufactured by thermal milling of polystyrene resin and styrene-butadiene rubber. The manufacturing method of anticorrosive paint in the invention is scientific and reasonable, and easy to implement. The anticorrosive paint has plump paint film, great adhesion force, fine tenacity, and stable property; and it also has excellent comprehensive functions such as acid proof, alkali proof, oil proof, aging resistance, and waterproof, static proof, and so on. So it can be used in facility, pipeline and building with corrosion all kinds of acid, alkali, oil, and water extensively.
Description
Technical field:
The present invention relates to a kind of novel single-component protective system and preparation method thereof, be specially a kind of modified polystyrene protective system and preparation method thereof.
Background technology:
In present protective system, exist peroxide ethene coating, epoxypaint, oxygen sulfonated polyethylene coating etc., but deficiency is respectively arranged.Peroxide ethene coating is owing to bigger molecular weight, and levelling property is undesirable, the paint film density difference, and viscosity is also very low, and its sticking power is also bad, and paint film easily comes off.Epoxypaint exists fragility big, and two components use inconvenient, to shortcomings such as the antiseptic property of sulfuric acid, nitric acid and oxalic acid are undesirable.Oxygen sulfonated polyethylene coating also exists two components, uses inconvenient.Package stability is poor, shortcoming such as acidproof, alkali resistance difference.So anxious appearance for the treatment of protective system of new generation.
Summary of the invention:
The object of the present invention is to provide a kind of novel single-component protective system and preparation method thereof, because of protective system is a single-component coating, so easy construction, have excellent acid, alkaline-resisting, oil resistant, ageing-resistant and comprehensive functions such as waterproof, anti-electrostatic, its paint film is plentiful, strong adhesion, good toughness, shelf characteric is stable.Its preparation method also is scientific and reasonable, easy to implement.
The present invention is achieved in that novel single-component protective system, contain solvent, film-forming resin, auxiliary agent and face, filler, its weight ratio is: solvent: film-forming resin: auxiliary agent: face, filler=100: (30～40): (3～8): (25～45), its optimum proportion are 100: (33～36): (4～6): (30～40).Wherein the weight of film-forming resin consists of: modified polystyrene resin: Resins, epoxy: petroleum resin=100: (20～28): (14～25) its optimum proportion is 100: (23～25): (15～18).And the weight of modified polystyrene resin consists of: polystyrene resin: elastopolymer=100: (2～5), its optimum proportion are 100: (3～4).Elastopolymer is a styrene-butadiene rubber(SBR).Novel single-component protective system, warp (1) is with the polystyrene resin modification; (2) extremely transparent with dissolution with solvents; (3) adding Resins, epoxy and petroleum resin mixes; (4) adding assistant, pigment.Filler.Stir; (5) solubilizing agent stirring, miscible.Adjust viscosity; (6) grind, filter and to make.Wherein modified polystyrene resin carries out hot milling by polystyrene resin and styrene-butadiene rubber(SBR) and makes, and the temperature of hot milling is 30～40 ℃, and speed is 140～280 rev/mins, and the time is 1～3 hour.
The present invention has the following advantages:
1) the present invention has excellent acid, alkaline-resisting.Oil resistant, ageing-resistant and comprehensive functions such as waterproof, anti-electrostatic, plentiful, the strong adhesion of this coating paint film, good toughness, lovely luster has concurrently corrosion-resistant and decorate properties, and is applied widely.
2) protective system easy construction of the present invention.And stable performance.Shelf lives is long.
3) preparation method of protective system of the present invention is scientific and reasonable, and is easy to implement.
4) modification of p-poly-phenyl ethenoid resin has major technological breakthrough aborning, has reduced production cost, and high economic benefit and social benefit are arranged.
