Abstract
The present invention relates to a polyurethane coating sprayed for one time and an application thereof. The weight percentages of the ingredients of the coating are as follows: 20 to 30 percent of hydroxylated acrylic resin; 20 to 30 percent of thermoplastic acrylic resin; 30 to 40 percent of butyl acetate, 0.2 to 1 percent of leveling agent; 0.2 to 1 percent of defoamer; 5 to 10 percent of solvent. In addition, 1 to 25 percent of color sizing can be added into the formula. The solid content of the hydroxylated acrylic resin and the thermoplastic acrylic resin is equal to or larger than 40 percent; the leveling agent is acrylic ester; the defoamer is organic silicon; the solvent is propylene glycol monomethyl ether acetate; the color sizing is mixture composed of inorganic or organic pigment, dispersant, acrylic resin and solvent. The coating of the present invention can be sprayed on the plastic shells of electronic products and electric appliances. The coating is characterized by simple spraying technique, low energy consumption, low cost, relatively low pollution, more environment-friendliness, etc.
Description
[technical field]
The present invention relates to organic coating, particularly relate to a kind of spraying that is used for electronics and electric equipment products plastic shell, and only need spray polyurethane paint for disposable spray finishing once.
[background technology]
At present, various electronics or electric equipment products have been widely used in people's the life as digital camera, notebook computer, mobile phone etc.The shell of this series products is made by plastics and plastic material mostly, and its shell all need be at surperficial sprayed protection and ornamental coating after machine-shaping.Mostly traditional casing is that with coating priming paint is the coating of thermoplastic acrylic, and finish paint is a polyurethane coating, and the general employing of its spraying coating process sprays the technology of priming paint, middle lacquer, finish paint respectively.Because of need repeatedly spray, so working (machining) efficiency is low, energy consumption height, cost height.
Along with the demand that extensive paint spay-coating is produced, spraying manufacturer more and more payes attention to the environmental-protecting performance of production efficiency and coating, therefore is badly in need of developing the disposable spray finishing coating of efficient more and environmental protection.
[summary of the invention]
The present invention is intended to address the above problem, and provides a kind of spraying coating process simple, and energy consumption is low, and is with low cost, pollutes relatively and lacks, more the polyurethane paint for disposable spray finishing of environmental protection.
The present invention also aims to provide the purposes of this and polyurethane paint for disposable spray finishing.
For achieving the above object, the invention provides a kind of polyurethane paint for disposable spray finishing, the weight percent of this coating consists of:
Hydroxylated acrylic resin 20～30
Thermoplastic acrylic resin 20～30
N-BUTYL ACETATE 30～40
Flow agent 0.2～1
Defoamer 0.2～1
Solvent 5～10
The preferred weight percent of this polyurethane paint for disposable spray finishing consists of:
Hydroxylated acrylic resin 25
Thermoplastic acrylic resin 23
N-BUTYL ACETATE 40
Flow agent 0.5
Defoamer 0.5
Solvent 11
The solids content of above-mentioned Hydroxylated acrylic resin and thermoplastic acrylic resin is equal to or greater than 40%, and wherein Hydroxylated acrylic resin is used for and solidifying agent reaction, and thermoplastic acrylic resin is used to improve the sticking power with ground.
Flow agent is an acrylate, is used to increase the coating surface levelling, and defoamer is an organosilicon, is used to eliminate the paint film steam bubble, and solvent is a 1-Methoxy-2-propyl acetate.
In another program of the present invention, the weight percent of polyurethane paint for disposable spray finishing consists of:
Hydroxylated acrylic resin 20～30
Thermoplastic acrylic resin 20～30
N-BUTYL ACETATE 20～30
Flow agent 0.2～1
Defoamer 0.2～1
Solvent 5～10
Mill base 1～25
The preferred weight percent of this polyurethane paint for disposable spray finishing consists of:
Hydroxylated acrylic resin 20
Thermoplastic acrylic resin 18.4
N-BUTYL ACETATE 32
Flow agent 0.5
Defoamer 0.5
Solvent 7.5
Mill base 21.1
The solids content of Hydroxylated acrylic resin and thermoplastic acrylic resin is equal to or greater than 40%.
Flow agent is an acrylate, and defoamer is an organosilicon, and solvent is a 1-Methoxy-2-propyl acetate, and mill base is after mechanical mill dispersive mixture is used to the coating toning by inorganic or pigment dyestuff, dispersion agent, acrylic resin, solvent.
The present invention also provides the purposes of this polyurethane paint for disposable spray finishing, and it can be used as the spraying coating of electronics and electric equipment products plastic shell.
Contribution of the present invention is, it is low because of need repeatedly spray the spray efficiency that causes that it has solved traditional casing coating, energy consumption height, problems such as cost height.Because traditional casing adopts twice spraying of the finish paint that priming paint that thermoplastic acrylic resin makes and Hydroxylated acrylic resin make more with coating, the present invention then is disposable polyurethane coating, therefore makes spraying coating process simpler, and energy consumption and cost are low, pollute relatively and lack, and environmental protection more.
