Abstract
The invention discloses a self-flame-retardant aqueous polyurethane industrial wood lacquer, which is prepared with the following raw materials in parts by weight: 75-85 parts of polycarbonate-based aqueous polyurethane emulsion, 6-10 parts of coalescing agent, 0.1-0.2 part of leveling agent, 0.05-0.3 part of wetting agent, 0.1-0.3 part of thickener, 1-3 parts of wax emulsion and 8-10 parts of deionized water. The self-flame-retardant aqueous polyurethane industrial wood lacquer of the invention can reach the standard of extinguishing upon departure from fire without any addition of any flame retardant agent, the mechanical properties and aging resistance thereof are excellent, and the decorative effect is good. Therefore, the invention is applicable to decoration of furniture, wooden handicrafts and the like.
Description
Technical field
The invention belongs to the polyurethane coating technical field, particularly self-flame-retardant aqueous polyurethane industrial wood lacquer.
Background technology
Advantages such as polyurethane industrial wood lacquer has the hardness height, and sticking power is good, wear resistance is good, fast drying, paint film light is plentiful are widely used in the protection and the decoration of products such as furniture, wood artwork.But do not have the polyurethane material of anti-flaming function in combustion processes, to discharge toxic gases such as HCN, CO, great potential safety hazard is arranged, the polyurethane material with anti-flaming function receives extensive concern.
Korea S's KR 20090017123A patent discloses a kind of preparation method of flame-proof thermoplastic polyurethane, and its anti-flaming function obtains through adding fire retardant such as phosphinate and trimeric cyanamide urate.Though the flame retardant effect that this method that adds the small molecules fire retardant can obtain to expect; But owing to there is not the flame retardant additive levels of reactive behavior bigger; Wherein melamine cyanurate consumption >=25 part often cause the mechanical property of paint film and the decline of hardness of paint film.And oiliness urethane needs high amounts of solvents, does not meet environmental requirement.
China's CN 101143988A patent discloses a kind of water anti-flaming carpentry paint.The base-material of this water anti-flaming carpentry paint is an acrylic ester emulsion, though have good flame retardant efficiency and decorative effect.But still be to add fire retardant, and there is the shortcoming of " hot sticky cold crisp " in the base-material polyacrylic ester, limited its application at aspects such as industrial wood lacquers.
Summary of the invention
The purpose of this invention is to provide a kind of can reaching and " promptly put out " self-flame-retardant aqueous polyurethane industrial wood lacquer that requires, with the security and the feature of environmental protection of improving the conventional urethane woodwork coating from fire.
Its technical scheme is: a kind of self-flame-retardant aqueous polyurethane industrial wood lacquer; It is characterized in that it is processed by following parts by weight of raw materials: polycarbonate type aqueous polyurethane emulsion 75-85, film coalescence aid 6-10, flow agent 0.1-0.2; Wetting agent 0.05-0.3; Thickening material 0.1-0.3, wax emulsion 1-3, deionized water 8-10.
Above-mentioned polycarbonate type aqueous polyurethane emulsion is one or both in negatively charged ion polycarbonate type aqueous polyurethane emulsion, positively charged ion polycarbonate type aqueous polyurethane emulsion, nonionic polycarbonate type aqueous polyurethane emulsion, negatively charged ion nonionic polycarbonate type aqueous polyurethane emulsion and the positively charged ion nonionic polycarbonate type aqueous polyurethane emulsion.
Above-mentioned film coalescence aid is one or both in N-Methyl pyrrolidone, propyl group phenylate and the butyl glycol ether.
Above-mentioned wetting agent is one or both in ROHM sylvite, polyacrylic acid sodium salt, ROHM aluminium salt and the polyoxyethylene.
Above-mentioned flow agent is one or both in polyether-modified ZGK 5, N-BUTYL ACETATE Mierocrystalline cellulose, soluble cotton and the polyvinyl butyral acetal.
Above-mentioned thickening material is one or both in aerosil, Natvosol and the Vinylpyrrolidone polymer.
Above-mentioned wax emulsion is one or both in paraffin, polythene wax emulsion and the tetrafluoroethylene wax emulsion.
Self-flame-retardant aqueous polyurethane industrial wood lacquer of the present invention is a base-material with the aqueous polyurethane emulsion, cooperates other auxiliary agents to make.With existing flame retardant type industrial wood lacquer relatively, self-flame-retardant aqueous polyurethane industrial wood lacquer of the present invention under the condition that does not add fire retardant, realized from fire promptly put out, the purpose of safety and environmental protection; And its mechanical property and ageing-resistant performance are excellent, and good decorating effect is applicable to the decoration of aspects such as furniture, wood artwork.
