The preparation method of described polystyrene paint is simple, comprise batching, dissolving, precipitation, reacting by heating, cold filtration, it is characterized in that adding in the filtrate after the polystyrene dissolving all batchings except that ethyl acetate, after the reacting by heating, cold filtration gets product after the adding ethyl acetate adjusting viscosity in filtrate again.
Optimum control is: need continuous stirring in the reaction process, 50～120 ℃ of temperature of reaction, 1.5～2 hours time.
Do not use aromatic solvents such as benzene,toluene,xylene among the present invention, and selected innoxious solvent for use, from having solved toxicity, pollution problem in essence.
The plastic waste polystyrene is nonpolar huge molecule, and structure does not almost have polar group to exist, so poor adhesive force.Added in our batching have polar group resin as properties-correcting agent, as acrylate copolymer, plant wet goods, make its formation " interpenetrating polymer networks " (claim IPN).Active polar group has hydroxyl-OH, amide group-CONH
2, carboxyl-COOH etc.Handle by modification, strengthened the film-forming properties that polystyrene paint is filmed greatly, sticking power to object, intensity and weathering resistance, the light permanency etc. of filming have also been increased simultaneously, such modification has formed alloy as added other metallic element in iron, performance has substantial leap, also can be described as " polymer alloy ".Butyl methacrylate, Viscotrol C, dioctyl phthalate (DOP) can both obviously improve ADHESION OF PAINTS power, and dioctyl phthalate (DOP) also has promoter action preferably to improving the snappiness that coating is filmed.
Initiator in the composition and catalyzer help to make batching to reach our design requirements.
Except that waste and old polystyrol was utilization of waste material, other all can directly be bought in the batching.
Coating of the present invention can use separately as basic coating (also can be described as varnish), also can allocate pigment, titanium dioxide, talcum powder etc. into and be prepared into colo(u)r coating (being also referred to as colored paint) use.Can modulate as the case may be, be applied on the multiple body surface, directly be coated in the usefulness that wood product surface is made decoration, be coated in metal products surfaces such as steel, iron and make protective coating, avoid getting rusty, make the metal products bright metalluster of antidimmer forever, colo(u)r coating is used to decorate interior and exterior wall.In order to realize some special performances, can in batching, add the function corresponding additive, strengthen flame retardant resistance as adding fire retardant, add fragrant ester and regulate smell or the like.Coating of the present invention also can be widely used on the facilities such as chemical industry equipment, various pipeline, bridge, electric tower, car, ship, harbour.
