Abstract
The invention provides an alcohol acid and polyurethane resin modified nitrocellulose matt varnish, containing the following components in parts by weight: 100 parts of nitrocellulose varnishes, 95-105 parts of alcoholic acid varnishes, 40-50 parts of curing agents and 80-90 parts of diluents. The alcohol acid and polyurethane resin-modified nitrocellulose matt varnish has the characteristics of rapid drying, good decorating effect, easy construction, excellent mechanical property, high film hardness and favorable chemical resistance.
Description
Technical field
The present invention relates to a kind of clear finish, be specifically related to a kind of nitro clear finish that is coated with the alcohol acid and polyurethane modification that is contained in the woodenware surface.
Background technology
The pyroxylin(e)finish of selling on the market now all is that to adopt Synolac or vinyl resin be raw material, adds the product that properties-correcting agent forms with the snappiness of improving it and sticking power.It has fast drying, good decorating effect, easy working advantage.Component like now general pyroxylin(e)finish is: paint host: thinner=1: 0.6-1.2; Its paint host mainly is made up of following component: contain soluble cotton 25-30%, DOP 3-6%, Synolac 20-25%, MIBK 5-10%, butylacetate 10-15%, toluene 5-10%, YLENE 5-10%, isopropylcarbinol 7-15%, ethylene glycol monobutyl ether 2-5%; Thinner mainly is made up of following component: isopropylcarbinol 10-15%, MIBK 10-15%, butylacetate 20-30%, YLENE 30-45%, ethylene glycol monobutyl ether 4-10%; But because its membrane formation mechanism is physical dryness fully, so drawbacks such as hardness of paint film is low, bad mechanical strength, not anti-solvent, heat-resisting, resistance to acids and bases difference.
Summary of the invention
The purpose of this invention is to provide a kind of alcohol acid and polyurethane resin modified nitrocellulose matt varnish, to overcome the bad mechanical strength that has pyroxylin(e)finish now and exist, the technological deficiency of chemicals-resistant difference.
