Abstract
The invention relates to a nitro-paint, in particular to a nitro-matte black paint, which is composed of the following components: a solvent; 1/8s nitrocotton; 1/4s nitrocotton; maleic resin; alkyd resin; a silane coupling agent; nano-alumina; carbon black; spherical organic matting powder; anti-settling agent; plasticizer; an acrylic ester leveling agent; and an organosilicon leveling agent. In the invention, by selection and collocation of nitrocotton and resin, the hardness and flexibility of a paint film are well balanced, and the adding of nano-alumina can significantly improve the hardness and wear resistance of the paint film; and the adding of spherical organic matting powder with good scratch resistance for replacement of traditional silicon dioxide matting powder can improve the wear resistance of the paint film and reduce frictional resistance. Therefore, the nitro-matte black paint provided in the invention has better hardness, flexibility and wear resistance.
Description
Technical field
The present invention relates to a kind of pyroxylin(e)finish, the inferior light black paint of particularly a kind of nitro.
Background technology
Pyroxylin(e)finish is that more common woodenware and finishing used coating at present.The main film forming matter of pyroxylin(e)finish is to be main with nitro-cotton, cooperates soft or hard resins such as Synolac, modified rosin resin, vinyl resin, aminoresin to form jointly.Generally also need add softening agent such as Witcizer 300, dioctyl ester, blown castor oil.Thinners such as solubility promoters such as solvent mainly contains true solvents such as ester class, ketone, pure ethers, alcohols and benzene class.Pyroxylin(e)finish is mainly used in the application, house decoration of woodenware and furniture, generally decorates aspects such as application, coated metal, general cement application.
The inferior light black paint of nitro generally is by thermoplastic acrylic resin, and softening agent, carbon black grind the back and form with nitro-cotton, solvent allotment.This lacquer has fast drying, and good weathering resistance and physical and mechanical properties have impression attractive in appearance, soft.Be applicable to vehicle, mechanism etc. need quick-drying article surface to decorate usefulness.But the pitch-dark ubiquity of nitro low gloss in the market wears no resistance, hard thing is drawn disadvantages such as being prone to bright trace.
