Problems solved by technology

[0003] Existing nitro paints are often added with halogen flame retardants because they are flammable. Although they have a good flame retardant effect, they are generally toxic and pollute the human body and the environment. Therefore, the existing nitro paints Paint, does not meet the current fire safety implementation requirements

Embodiment Construction

[0016] Nitro paint prepared by using halogen-free flame retardant, its component distribution ratio is 13% of nitrocellulose, 27% of mixed solution, 3% of mixing aid, 7% of halogen-free flame retardant, 30% of plasticized resin, transparent 10% raw material solution, 10% color paste; the mixed solution is a true solvent of esters, ketones, and alcohol ethers; the film-forming agent is mainly nitrocellulose, combined with plasticized resin alkyd resin, modified rosin resin, and acrylic resin , amino resin soft and hard resin together, and also added with dibutyl phthalate, dioctyl phthalate, oxidized castor oil plasticizer.

[0017] Its specific technological process includes the following steps:

[0018] In a mixing container, mix and stir nitrocellulose, mixed solution, and mixing aid for 20 minutes, then add halogen-free flame retardant, transparent raw material solution, mix and disperse at high speed for 25 minutes, then add plasticizing resin and color paste to it and mix...

Abstract

The invention discloses nitrocellulose lacquer which is prepared through utilizing free halogen flame retardant, and adding free halogen flame retardant on the basis of traditional nitrocellulose lacquer, whose proportion of components is that 13-18% nitrocellulose, 27-35% mixing solvent, 1-3% mixing auxiliary agent, 30-35% plasticizing agent, 7-10% transparent raw material liquid diluent and 10-15% color paste, which is characterized in that 7-10% free halogen flame retardant is added in the components. The invention further discloses a preparation process of nitrocellulose lacquer. The invention provides environment-friendly, no pollution nitrocellulose lacquer with excellent flame-retardant effect under the conditions of keeping basic property of original nitrocellulose lacquer and no changing functions.

Description

technical field [0001] The invention relates to a flame-retardant nitro-lacquer prepared by using a halogen-free flame retardant. Background technique [0002] Nitro lacquer is a relatively common wood and decoration coating at present. The advantages are good decorative effect, simple construction, fast drying, low requirements on the coating environment, good hardness and brightness, less prone to paint film defects, and easy repair. The disadvantage is that the solid content is low, and more constructions are required to achieve better results; the durability is not very good, especially for internal use of nitro paint, which has poor gloss and color retention, and it will be damaged if it is used for a long time. Prone to disadvantages such as loss of light, cracking, discoloration, etc.; paint film protection is not good, not resistant to organic solvents, not heat-resistant, not corrosion-resistant. Nitro lacquer is mainly used in wood and furniture coating, home dec...
