Abstract
The invention provides a spraying treatment method for mobile telephone shells. The mobile telephone shells are provided with surfaces to be sprayed. The spraying treatment method comprises the steps of spraying, wherein liquid coatings with the viscosity ranging from 1 cP to 8 cP are sprayed on the surfaces of the mobile telephone shells; high-temperature pre-baking, wherein the mobile telephone shells are baked for 10-90 seconds at 50-80 DEG C; low-temperature pre-baking, wherein the mobile telephone shells are baked for 1-4 minutes at 30-50 DEG C, and the inclination degrees of the sprayed surfaces of the mobile telephone shells are controlled to be within 20 degrees in the baking process; and high-temperature drying, wherein the mobile telephone shells are dried for 5-15 minutes at 50-80 DEG C. In the high-temperature pre-baking process, the mobile telephone shells are baked for 30 seconds at 70 DEG C. Through the high-temperature pre-baking process, the mobility of the coatings is lowered, the low-temperature pre-baking process can be carried out when the inclination degrees of the mobile telephone shells are smaller than 20 degrees, the mobile telephone shells can be placed at greater inclination angles in the high-temperature drying process, and therefore the utilization rate of baking equipment can be increased and the baking cost can be lowered.
Description
Technical field
The present invention relates to a kind of phone housing spraying process for treating, belong to spraying technology field.
Background technology
The shell of general consumer electronic product such as mobile phone or computer etc. generally carries out the application of outer surface to reach to beautify the decorative purpose of shell. During spraying, paint or ink are sprayed on phone housing surface, form film after solvent volatilization. When phone housing is dried, film above when must keep the baking of spray-coating surface general horizontal to prevent slant setting moves down, make film lower limb thick, but the baking of lamellar phone housing horizontal positioned makes the phone housing amount that every layer of baking oven is placed less, toasts relatively costly.
Summary of the invention
The present invention provides a kind of phone housing spraying process for treating, it is possible to overcome the above defect.
For solving above technical problem, the present invention provides following technical scheme: a kind of phone housing spraying process for treating a, it is provided that phone housing, and this phone housing has to be sprayed, spraying, is sprayed into the surface of phone housing by the liquid coating that viscosity is 1cP～8cP, high temperature prebake conditions, is placed in phone housing under the temperature conditions of 50 DEG C～80 DEG C and toasts 10 seconds to 90 seconds, low temperature prebake conditions, is placed in phone housing under the temperature conditions of 30 DEG C～50 DEG C and toasts 1 minute to 4 minutes, and in baking process, the gradient of phone housing spray-coating surface is within 20 degree, high temperature is dried, and is placed in by phone housing under the temperature conditions of 50 DEG C～80 DEG C and toasts 5 minutes to 15 minutes, during high temperature prebake conditions, phone housing is placed under the temperature conditions of 70 DEG C and toasts 30 seconds, baking process makes the spray-coating surface of the phone housing projected area in the plane being perpendicular to action of gravity direction reach between maximum and maximum 0.966 times, during low temperature prebake conditions, phone housing is placed under the temperature conditions of 45 DEG C and toasts 3 minutes, liquid coating is sprayed onto on phone housing formed coating layer thickness be 5 μm-60 μm, described liquid coating is acrylic coating, solvent in described liquid coating is oxolane, acetone, methyl acetate, ethyl acetate, butanone, isopropyl acetate, the positive acetone of methyl, positive propyl acetate, methyl iso-butyl ketone (MIBK) (MIBK), isobutyl acetate, 2-nitropropane, n-butyl acetate, propylene glycol monomethyl ether, methyl isoamyl ketone (MIAK), methyl amyl acetate, n-butyl propionate, propylene glycol methyl ether acetate, pentyl acetate, methyl-n-amyl ketone, isobutyl isobutyrate, ethoxy ether, cyclohexanone, glycol monobutyl ether, propylene glycol monopropyl ether, ethyl cellosolve acetate, isobutyrone (DIBK), glycol propyl ether, DAA, butyl glycol ether, propandiol butyl ether, formic acid-2-ethylhexyl ester, butyl glycol ether acetas, dipropylene glycol methyl ether, glycol diacetate, diethylene glycol dimethyl ether, diethylene glycol ether, diethylene glycol propyl ether, glycol hexyl ether, diethylene glycol ether acetas, butyl, ethylene glycol-2-ethyl hexyl ether, butyl acetas, the third two single phenyl ethers, methanol, ethanol, isopropanol, normal propyl alcohol, 2-butanol, isobutanol, n-butyl alcohol, methyl isobutyl carbinol, amylalcohol, Hexalin, dichloromethane, perchloroethylene, toluene, Petroleum, the mixture of one or more in dimethylbenzene.
High temperature prebake conditions can quickly remove the partial solvent in spraying liquid coating, reduces the mobility of film. The time of high temperature prebake conditions is shorter, it is possible to when avoiding high temperature, the solvent in film reacts with the surface of phone housing and corrodes phone housing. Low temperature prebake conditions can remove the partial solvent in spraying liquid coating slowly. During low temperature prebake conditions, film has certain mobility, and the rate of volatilization of solvent is less simultaneously so that after solvent volatilizees, and film can flow in the hole that solvent volatilization is formed, thus forming the defects such as pin hole owing to solvent evaporation is too fast when avoiding toasting. High temperature is dried and the film on phone housing surface can be made to parch completely by the solvent thoroughly removed in film. High temperature prebake conditions, low temperature prebake conditions are dried three steps with high temperature and are coordinated the coating thickness making spraying uniformly and to be not easily formed the defects such as pin hole. Simultaneously, high temperature prebake conditions reduces the mobility of film, can carry out when making low temperature prebake conditions in the phone housing gradient scope less than 20 degree, and during high temperature drying, phone housing can be put with bigger angle of inclination, thus improving the utilization rate of roasting plant, reduce baking cost.
