Abstract

The invention discloses a pyroxylin lacquer with low smell, wherein the pyroxylin lacquer has no benzene hydrocarbon, and the lacquer formula includes 10 percent-25 percent by weight of at least one resin, 25 percent-55 percent by weight of at least one of alcohol ether solvent, ester solvent or alcoholic solvent, , 20 percent-50 percent by weight of at least one curing agent, plasticizer and additive, the pyroxylin lacquer of the invention uses non-benzene solvent, and ensure the superiority of pyroxylin lacquer per se, so as to effectively avoid environmental pollution produced in production, construction and using process of the benzene hydrocarbon, and health hazard to production operator and constructer.

Description

Technical field: [0001] The invention relates to a paint composition, in particular to a low-odor nitro paint without benzene solvent. Background technique: [0002] At present, there are many kinds of paints and coatings on the market, and nitro paint has the characteristics of economical benefits, simple proportioning, good leveling, smooth hand feeling, fast drying, soft luster, tough and durable film formation, and can highlight the natural texture of wood , The effect is unique, Nitro paint is widely used in wood opening (American painting) decoration and interior decoration of hotels, shopping malls, cars and trains due to its excellent construction performance and rich and varied effects. However, at present, benzene solvents such as benzene, toluene, and xylene are used in the existing nitro paint manufacturing formula, and aromatic hydrocarbon solvents such as benzene, xylene, etc. produce anesthesia and stimulation to the human nervous system, and what is more seri...
