Abstract
The invention provides a kind of aluminium enamel powdered frit and utilize this powdered frit to carry out the method for aluminium enamel spraying.The weight ratio of aluminium enamel glaze powder component and each component is: the aluminium enamel glaze: 100 parts; 0.1～2 part of liquid polymerizable dimethyl-silicon siloxanes.The method of utilizing this powdered frit to carry out the aluminium enamel spraying comprises the steps: 100 parts of aluminium enamel glaze and 0.1～2 part of liquid polymerizable dimethyl-silicon siloxanes are mixed the fineness of back ball milling to regulation, place 150-250 ℃ of oven dry 30 ± 5 minutes, with electrostatic gun powdered frit is sprayed on the aluminium sheet, place 550-570 ℃ of firing furnace sintering then.Advantage of the present invention is: one, adopt the method with the dry fabrication aluminium enamel powdered frit of aluminium enamel glaze and liquid polymerizable dimethyl siloxane mixing and ball milling, directly electrostatic spraying has solved aluminium enamel glaze slip rheological property variation shortcoming greatly on aluminium sheet then.Two, manufacture craft is simple, and cost is lower, and is safe and reliable, can produce in batches.
Description
Technical field:
The present invention relates to enamel enamel technical field, be a kind of aluminium enamel powdered frit and utilize this powdered frit to carry out the method for aluminium enamel spraying.
Background technology:
Enamel is a kind of application material very widely, has important purposes in chemical industry, building and daily life product.For a long time, the glaze piece of aluminium enamel is that form with aqueous suspensoid is applied on base substrate or the workpiece always.Because the fusing point of aluminium has only 650 ℃, the firing temperature of general aluminium enamel is at 550～570 ℃.Wet aluminium enamel glaze slip, the big pH value of alkalescence is about 12, and the free alkali in the glaze slip is too much, and glaze slip and aluminium base generated reactive gas cause the enamel face pin hole to occur.In addition, the control of aluminium enamel glaze slip rheological is to produce one of problem of the difficulty that qualified aluminium enamel product run into.And deposit two days later if use at the aluminium enamel glaze slip, must readjust glaze slip, otherwise can stop badly, produce glaze slip and drip the extension phenomenon.
Summary of the invention:
In order to solve above-mentioned the deficiencies in the prior art, it is simple to the invention provides a kind of manufacture craft, and cost is lower, and is safe and reliable, the aluminium enamel powdered frit that can produce in batches and utilize this powdered frit to carry out the method for aluminium enamel spraying.
Technical scheme provided by the invention is: a kind of aluminium enamel powdered frit, and the weight ratio of component and each component is: the aluminium enamel glaze: 100 parts; 0.1～2 part of liquid polymerizable dimethyl-silicon siloxanes.Described aluminium enamel glaze piece can be EAF8019 or the GL4317 of commercially available Ferro; The AT6000 of Pemco or any glaze piece among the AT6110.In order to eliminate the rheology problem of glaze slip, the dry spraying of powdered frit has caused everybody concern.Though the existing static charge that adopts is sprayed on the blank plastics, full organic dust, because of plastics, full organic dust are good electrical insulators, high resistivity; And powdered frit has low-down resistivity, because the low resistivity of powdered frit inherent, electric charge is missed from the glaze powder particles easily, and the glaze powder particles can only be moved on blank carefully, and powdered frit just is unlikely and splits away off.On powdered frit, impose the liquid polymerizable dimethyl siloxane of relative high resistivity according to the present invention, behind glaze piece ball milling, dimethyl siloxane at normal temperatures can not be in the surperficial completely solidified of powdered frit, must behind ball milling, heat-treat powdered frit, make dimethyl siloxane be solidificated in the powdered frit surface, to improve the resistivity of powdered frit.
A kind of method of utilizing this powdered frit to carry out the aluminium enamel spraying, this method comprises the steps: 100 parts of aluminium enamel glaze and 0.1～2 part of liquid polymerizable dimethyl-silicon siloxanes are mixed the fineness of back ball milling to regulation, place 150-250 ℃ of oven dry 30 ± 5 minutes, with electrostatic gun powdered frit is sprayed on the aluminium sheet, place 550-570 ℃ of firing furnace sintering then.
The weight of described aluminium enamel glaze 90% is by 200 mesh standard sieves.
Advantage of the present invention is: one, adopt the method with the dry fabrication aluminium enamel powdered frit of aluminium enamel glaze and liquid polymerizable dimethyl siloxane mixing and ball milling, directly electrostatic spraying has solved aluminium enamel glaze slip rheological property variation shortcoming greatly on aluminium sheet then.Two, manufacture craft of the present invention is simple, and cost is lower, and is safe and reliable, can produce in batches.
Embodiment:
Embodiment 1:
The AT6000 glaze piece of 400 grams and the dimethyl siloxane of 1.2 grams are put into the ball grinder ball milling that contains 1 liter of 600 ballstone volume, obtain the powdered frit of the weight of 200 mesh screen residues 5%, this powdered frit is placed 220 ℃ of oven dry 30 minutes, powdered frit is sprayed on 1100 aluminium sheets of 150 * 150mm with a static gun that imposes 80KV voltage, the powdered frit quantity for spray is 4 grams, burnt till under 560 ℃ temperature 6 minutes then, the appearance of coat after burning till is good.
Embodiment 2:
The GL4317 glaze pieces of 400 grams and the dimethyl siloxanes of 2.0 grams are put into the ball grinder ball milling that contains 1 liter of 600 ballstone volume, make glaze piece 80 order all-pass mistakes, and need have 90% weight to pass through at 200 mesh sieves.This powdered frit is about 200 ℃ temperature heating 30 minutes, with one the static gun of 80KV voltage in addition is applied over powdered frit on 3003 aluminium sheets of 100 * 100mm with electrostatic spraying, and the powdered frit quantity for spray is 2.5 to restrain.Burnt till under 560 ℃ temperature 6 minutes, the visual appearance after burning till is good.The above-mentioned powdered frit that makes after humidity is to deposit three days under the 40-50% environment, is sprayed on 3003 aluminium sheets, also can obtains the good surface appearance quality after burning till.
