Description

Tubulose enamelled iron skill assembly and preparation method thereof

(1) technical field:

The present invention relates to the iron skill assembly that a kind of usefulness connects combination jube or door and window; The invention still further relates to the method for making this iron skill assembly.

(2) background technology:

In the prior art, the iron skill assembly that building industry is used, as jube and the outdoor antitheft jube window of resident that is connected with on office or the residential quarters shadow-mark wall, the structure of its iron skill assembly, normally solid shape of cast iron or hollow iron pipe shape, all be at iron skill assembly outer surface brushing corrosion-resistant oil enamelled coating, and the surface of internal cavity of described tubular iron skill assembly can't brushing antirust oil enamelled coating.Exist not enough: under abominable natural environment wind, Exposure to Sunlight and sleet corrode, the very fast corrosion in inner chamber metal surface of described tubular iron skill assembly, and brushing comes off also easily aging the peeling off of skin of paint of its outer surface, and the corrosion of having accelerated tubular iron skill assembly damages.And described cast iron solid-iron skill assembly material consumption is big, the production cost height.

(3) summary of the invention:

The object of the present invention is to provide a kind of tubulose enamelled iron skill assembly, be intended to strengthen its ageing-resistant and resistant tarnishing, improve service life and save the metal material consumption; For this reason, the present invention also will provide the method for making this tubulose enamelled iron skill assembly.

For achieving the above object, tubulose enamelled iron skill assembly of the present invention improves and is: on the inner chamber and its outer surface of body, dip-coating has the enamel paint layer respectively; The composition of described enamel paint comprises: 48.5～52.5 weight portions be porcelain, 6.18～6.83 parts by weight of clay of matrix, the antimony oxide of 1.14～1.26 weight portions, the barium molybdate of 0.76～0.84 weight portion, the zinc oxide of 0.48～0.50 weight portion, the natrium nitrosum and the borax of each 0.95～1.05 weight portion with silica, and the water of 37～41 weight portions; Described enamel paint layer is 0.15～0.30 millimeter at the thickness of tube cavity and its outer surface respectively.The shape of cross section of common described body is circle, ellipse, rectangle, square, triangle, hexagon or dolioform wherein a kind of.

The method that the present invention makes tubulose enamelled iron skill assembly comprises following step: (1) dip-coating on the inner chamber of body and its outer surface has enamel paint, through 280～300 ℃ of oven dry; (2) check the leakage spot of repairing the inside and outside surperficial dip-coating porcelain layer inequality of body; (3) 900 ℃ of sintering, cooling.

Wherein, the preparation method of enamel paint is: with 48.5～52.5 weight portions is porcelain, 6.18～6.83 parts by weight of clay of matrix, the antimony oxide of 1.14～1.26 weight portions, the barium molybdate of 0.76～0.84 weight portion, the zinc oxide of 0.48～0.50 weight portion, the natrium nitrosum and the borax of each 0.95～1.05 weight portion with silica, and the water of 37～41 weight portions is in harmonious proportion evenly, by ball mill break-in 8～9 hours, filter through 70～90 mesh sieves.

Because the present invention is on the inside and outside surface of body, evenly dip-coating has the enamel paint layer that densification is firm, non-oxidizability is strong respectively, strengthened the ageing-resistant and resistant tarnishing of tubulose enamelled iron skill assembly, after tested: the present invention improves three times than the tubular iron skill assembly of the outer brushing paint of prior art service life; Its material usage only is 1/3 of a cast iron solid-iron skill assembly, has obviously saved metal material.
