Abstract
The present invention discloses novel acrylic acid resin undersurface synthetic paint for an automobile chassis, which is prepared from the following materials by weight percentage: 5 to 10 percent of 50 percent hydroxy acrylic acid resin (molecular weight is between 25,000 and 30,000), 37 to 57 percent of 50 percent acrylic acid (molecular weight is between 45,000 and 60,000), 1 to 3 percent of carbon black, 3 to 5 percent of talcum powder, 2 to 3 percent of antirust agent, 20 to 25 percent of solvent, 1 to 4 percent of permanent white and 3 to 7 percent of sodium tripolyphosphate. The paint has the advantages of low film forming temperature, high strength and convenient construction.
Description
Technical field
The invention belongs to the technical field of chemical paint, particularly a kind of automobile chassis novel acrylic resin bottom face synthetic lacquer.
Background technology
At present, large component such as automobile chassis etc. needs two step mopping---priming paint and finish paints at least, and it is loaded down with trivial details to construct, the cost height, and intensity is low.And at present the acrylic polyurethane coating that generally uses is a two-pack paint, the price height, and construction inconvenience after double compositions paint prepares, must use up in 6 hours, otherwise easily gel is scrapped, and paint film needs 80 degrees centigrade of oven dry or Air drying could carry after 24-48 hours.Disclose " a kind of acrylic coating varnish for limousine " as Chinese patent CN1102196, its film-forming temperature height can only use as finish paint.Chinese patent CN1105689 discloses " flushing resistant high-temperature boiling resistant metallic paint ", be the coating that forms with the acrylic resin modified epoxy, though its strength ratio is higher, but its film-forming temperature is than higher, the cost height is not suitable for the construction of the large-scale workpiece as the small batch automobile chassis.Chinese patent CN1235995 discloses " high brightness luminous paint and manufacture method thereof ", with luminescent powder with make after acrylic resin mixes, also be to use as finish paint.
Summary of the invention
The object of the present invention is to provide a kind of film-forming temperature low, intensity is big, the novel single component acrylic resin bottom face synthetic lacquer of easy construction.
Technical scheme of the present invention is: novel acrylic resin bottom face synthetic lacquer of the present invention, form by following substances in percentage by weight:
Hydroxylated acrylic resin 50% (molecular weight 25000-30000) 5-10%
Acrylic resin 50% (molecular weight 45000-60000) 37-57%
Carbon black 1-3%
Talcum powder 3-5%
Rust-preventive agent 2%-3%
Solvent 20-25%
Barium sulfate 1-4%
Tripoly phosphate sodium STPP 3-7%
Antirust auxiliary agent is formed proportioning (weight):
Zinc phosphate: tripoly phosphate sodium STPP: iron oxide black=5:3:10
Solvent composition proportioning (weight) is:
Dimethylbenzene: butanols: cyclohexanone=7:1:2
Advantage of the present invention is: the present invention has utilized the acrylic resin adhesiveproperties good, has plastic characteristics.Molecular weight is that 45000-60000 acrylic resin has stronger adhesiveproperties, and intensity is big, and rigidity is strong.And that molecular weight is 25000-30000 Hydroxylated acrylic resin plasticity-is strong, flexible strong, can increase the folding resistance of lacquer.These two kinds of acrylic resins mix, and the paint of making promptly has stronger bonding strength, has plasticity-again, promptly can use as priming paint, can be used as finish paint again and use.
Novel acrylic resin bottom face synthetic lacquer of the present invention adds rust-preventive agent, can reach antirust purpose.Simultaneously, the composition of rust-preventive agent is a zinc phosphate, tripoly phosphate sodium STPP, and the effect of phosphatization can be played in the iron oxide black, strengthens the bonding strength of paint and metal parts.
Novel acrylic resin bottom face synthetic lacquer of the present invention can adopt traditional aerial spraying, the construction of methods such as electrostatic spraying or airless spraying.2 hours at normal temperatures surface dryings need not baking from doing, and saved the energy in 12 hours.
Therefore, the present invention has that film-forming temperature is low, and intensity is big, the advantage of easy construction.
Embodiment
The present invention is made up of following substances in percentage by weight:
Hydroxylated acrylic resin 50% (molecular weight 25000-30000) 8.5%
Acrylic resin 50% (molecular weight 45000-60000) 52.4%
Carbon black H2 2.35%
Talcum powder 1250 orders 4%
Rust-preventive agent 2.5%
Barium sulfate industry 2.0%
Tripoly phosphate sodium STPP industry 5.5%
Dimethylbenzene industry 15%
Butanols industry 2.4%
Cyclohexanone industry 4.3%
Antirust auxiliary agent is formed proportioning (weight):
Zinc phosphate: tripoly phosphate sodium STPP: iron oxide black=5:3:10
Novel acrylic resin bottom face synthetic lacquer of the present invention, its production unit is identical with common lacquer with technology.Can adopt aerial spraying, electrostatic spraying and the construction of airless spraying method, more than the one-pass film-forming 35um.Paint film mechanics and corrosion resisting property are greatly improved, and salt-fog test is more than 240, and temper(ing) is more than 400 hours.
