Embodiment 1

[0014] A kind of water-based environment-friendly nitro-lacquer, its main agent is composed of by weight percentage: Hydroxy acrylic resin 10%, plasticizer 2%, BYK192 0.8%, ethyl ester 4%, butyl ester 6.2%, low-second nitrocellulose 24%, Butanol 10%, acrylic emulsion 2%, propylene glycol methyl ether acetate 1%, (it is a slow-drying solvent, the purpose is to increase the construction operation range), water 40%. The weight percent of its corresponding diluent is composed of ethanol 5%, isobutanol 15%, ethyl acetate 20%, butyl acetate 42.9%, propylene glycol methyl ether acetate 15%, DBE 2%, deodorant 0.1%. The preparation method of water-based environment-friendly nitro varnish is as follows: input resin, cotton pulp, plasticizer and solvent in sequence, add the dummy powder and other substances under stirring, clean the side powder with solvent, and then disperse at high speed for 30 minutes at 1500 rpm. The preparation method of the diluent is to feed in order, stir and mix...

Abstract

The invention discloses water-based environment-friendly nitrolacquer and a construction method for the same. The water-based environment-friendly nitrolacquer comprises, in weight percentage, 8-10% of water-based resin, 2-3% of plasticizer, 0.5-1% of dispersing agent, 4-5% of ethyl ester, 6-8% of butyl ester, 20-25% of low-second nitrocellulose, 6-10% of butyl alcohol, 2-3% of emulsion, 1-2% of construction binder and the balance water. The water-based environment-friendly nitrolacquer is highly environment-friendly, low in production cost and excellent in performance.

Description

technical field [0001] The invention relates to a coating in the chemical industry, in particular to a protective coating applied to the surface of industrial wood furniture. Background technique [0002] At present, most of the wood coatings used in my country are solvent-based, and these wood coatings contain a large amount of volatile organic compounds (VOC), which seriously endanger the health of production personnel and construction personnel. With the enhancement of people's awareness of environmental protection, traditional solvent-based coatings are facing severe challenges. Water-based coatings have the advantages of non-toxic, non-flammable, and non-polluting environment. Water-based coatings combine the high performance of solvent-based coatings with the low VOC content of water-based coatings, which have good environmental effects and relatively convenient construction. However, my country's water-based coatings are currently in the initial stage of technology, ...
