Abstract

A processing method for spraying an aluminum curtain wall plate with fluorocarbon coating comprises preliminary treatment of a general single layer aluminum plate which is composed of degreasing, corroding, surface conditioning and chromaking, cleaning between every process and final drying, wherein, a plurality of spray guns are arranged according to various colors of marble and the required decorative design based on spraying fluorocarbon coating as primer after the preliminary treatment, and by adjusting the atomization pressure of the spray guns and the viscosity of the coating, the aluminum curtain wall plate with a parian presentation effect can be sprayed, therefore the characteristics of spraying aluminum curtain wall plate with fluorocarbon coating such as firmness, elegant appearance and long service can be maintained, the beauty and the unique charming of a marble ornament can be embodied, and the train of thought about spraying an aluminum curtain wall plate with fluorocarbon coating is broadened.

Description

A kind of processing method of spraying aluminum curtain wall plate with fluorocarbon coating

Technical field

The invention belongs to a kind of preparation method of building and ornament materials, specially refer to the preparation method of used for building exterior wall aluminum alloy curtain walls.

Background technology

Aluminum alloy curtain walls is one of building and ornament materials of current international popular, has overcome glass curtain wall and has caused a series of shortcomings such as light pollution, and this curtain wall panel processing is relatively simple, and material is firm, and service time is remote relatively.But according to the retrieval; Present aluminum alloy curtain walls, surface all are to adopt the Kynar-500 paint spraying, and this material is a kind of fluorocarbon resin coating, have to decorate preferably and barrier propterty.But before the present invention made, the Aluminum curtain wall plate of existing fluorocarbon coating spraying all was a kind of simple tone.For example: " material protection " magazine the 32nd volume of publishing in February, 1999, the 2nd phase, the 24th to 25 page of basic preparation method that has just provided this decorative aluminum plate.The fluorocarbon coating decorative aluminum plate of single tone, though advantage on a lot of serviceabilities is arranged, decorative effect is restricted, and has influenced the generally use of this high-quality ornament materials.

Summary of the invention

Purpose of the present invention, it is the shortcoming that overcomes the single tone of spraying aluminum curtain wall plate with fluorocarbon coating, make the diversification of aluminum facade color, especially produce the Aluminum curtain wall plate that people generally like with emmarble effect, make this ornament materials both have aluminum facade and decorate novelty, the advantage that barrier propterty is good has the special decorative effect of parian again, has bigger market prospects.

The present invention is achieved by the following technical measures:

Earlier plan is processed into the single layer aluminium sheet base material of the fluorocarbon coating aluminium sheet of parian, carries out pre-treatment, promptly generally carry out with following operation with the method for prior art: degreasing, to clean, corrosion is cleaned, and table accent (pickling) cleans, and chromaking is handled, and cleans oven dry.

Aluminium sheet through pre-treatment is manually reached the standard grade on spraying coating line, first spraying fluorocarbon coating priming paint and through levelling, spray the fluorocarbon coating finish paint then,, set gradually the spray gun of the fluorocarbon coating of different colours simultaneously according to institute's marbleize color, kind and quantity, decorative pattern size, adjust the atomizing pressure of corresponding spray gun, carry out the marbling spraying, carry out levelling afterwards, spray coating varnish at last, drying behind the levelling can roll off the production line after the cooling.

The key of this processing method also is: when spraying fluorine carbon colour-wash, and the viscosity of strict coating and the atomizing pressure of spray gun, the viscosity of general coating is Ford cup (F-4) 30~40 seconds; The atomizing pressure of spray gun is 0.05~0.1 MPa.

Through the parian fluorocarbon coating Aluminum curtain wall plate of this processing method moulding, be used on the external wall of building not only firmly, generous, use of the remote pastly, and embodied the attractive in appearance and unique charm of emmarble.

The specific embodiment

The invention will be further described below in conjunction with embodiment.

Embodiment: a kind of to have light brown be the end, on have parian fluorocarbon coating Aluminum curtain wall plate black, white, coffee-like color spot to process like this:

Single layer aluminium sheet to be processed carries out pre-treatment earlier, the medicament that the material of pre-treatment all selects for use Shanghai Henkel chemicals Co., Ltd to produce.At first base material is carried out degreasing, degreasing agent is selected low concentration P3-almee 08 for use, and skimming temp is 50~60 ℃, and degreasing time is 5~8 minutes, cleans with running water after the degreasing; Carry out corrosion treatment with P3-almee 057 caustic corrosion agent again, treatment temperature is 40~50 ℃, and the processing time is 0.5~2 minute, still cleans with running water after the processing; Table is transferred at normal temperatures then, carries out pickling with Deoxidizer 395H, and the pickling time is 0.5~1 minute, still cleans with running water after the pickling; Carry out chromaking at last and handle, the chromaking agent is Alodime AC 6100, and the chromaking temperature is 20~40 ℃, and the chromaking time is 1~2 minute, still clean after the chromaking with running water, and standby after drying 20~30 minutes under 80~85 ℃ of conditions.

Can carry out fluorocarbon-sprayed technology after the pre-treatment: elder generation is 70% kynar coating spraying priming paint with fluorinated volume, adopt winter toluene or butanone to make solvent, make solvent with dimethylbenzene and carbitol summer, the accent dope viscosity is Ford cup (F-4) 16~19 seconds, and air pressure is 0.5~0.6 MPa.The spray gun atomizing pressure is 0.2 MPa, and going out the lacquer amount is 70~80cc.The spraying priming paint after with 10 minutes levellings.

Continue after, successively the spraying black, white, coffee-like coating, the viscosity useable solvents of coating is adjusted, viscosity is Ford cup (F-4) 30~40 seconds, air pressure is 0.5~0.6 MPa.Atomizing pressure is 0.05 MPa, and going out the lacquer amount is 40cc, according to the marbling requirement, can adjust the spray gun atomizing pressure and be satisfied.

Need equally about 10 minutes levellings behind the spraying colored paint, spray coating varnish again, coating also useable solvents to be diluted to viscosity be Ford cup (F-4) 16~19 seconds, air pressure is 0.5~0.6 MPa.The spray gun atomizing pressure is 0.2 MPa, and going out the lacquer amount is 70~80cc, after about 15 minutes levellings toasted 20~30 minutes under 240~250 ℃ of hot conditions, can come out of the stove, and rolls off the production line after cooling.

According to marbleize, decision spray gun quantity, setting, arrangement and adjustment spray gun atomizing pressure, thus obtaining different marmorean appearance, these all are within the technical program scope.

The whole process quality requirement of parian fluorocarbon coating Aluminum curtain wall plate is also very strict, and American Architecture industry association criterion AAMA-605.02.90 is the application international standard of generally acknowledging, also is the technical standard that the technical program can reach.
