Abstract

The invention relates to manufacturing of an enamel curtain wall plate, in particular to a manufacturing method for a photocatalysis self-cleaning enamel curtain wall plate. The manufacturing method includes the steps that dosing raw materials, manufacturing glaze melting blocks, manufacturing glaze slip, and conducting firing. The manufacturing method is mainly used for overcoming the shortcomings of an existing photocatalysis function material. According to the manufacturing method for the photocatalysis self-cleaning enamel curtain wall plate, titanium dioxide nanometer liquid and overglaze are organically combined through formula design and hard firing, and the photocatalysis self-cleaning enamel curtain wall plate has the beneficial effects of being large in bonding strength, good in self-cleaning effect, long in service life, even in color and the like.

Description

A kind of preparation method of catalytic self-cleaning enamel curtain wall panel
Technical field
The present invention relates to the preparation of enamel curtain wall panel, be specifically related to a kind of preparation method of catalytic self-cleaning enamel curtain wall panel.
Background technology
The physical and mental health of the atmospheric pollution in city not only grievous injury people, also brings severe contamination to skin, have impact on the attractive in appearance of city.The cleaning of external wall not only can cause secondary pollution to environment, too increases the risk of clean and maintenance cost and working aloft.Also some material with photo-catalysis function is being promoted the use of in the market, and these materials are mostly make in the mode of liquid spray at low temperatures, has that bonding strength is not high, work-ing life is short, it is uneven to spray, affect the defects such as surface color.
Summary of the invention
The defect that the present invention exists mainly for existing Photocatalysis Function Material, invent a kind of preparation method of catalytic self-cleaning enamel curtain wall panel, nano titania liquid and cover-coat enamel are burnt till by the design of filling a prescription and high temperature and organically combine by the method, have the advantages such as bonding strength is large, self-cleaning effect good, the life-span is long, uniform color.
Above-mentioned technical problem of the present invention is implemented by the following technical programs: a kind of preparation method of catalytic self-cleaning enamel curtain wall panel, comprises the following steps:
(1) required cover-coat enamel composition of raw materials: SiO by weight percentage 2: 30 ~ 50%, CaO:1 ~ 8%, NaNO 3: 3 ~ 10%, Al 2o 3: 1 ~ 5%, B 2o 3: 15 ~ 20%, TiO 2: 10 ~ 20%, Na 2siF 6: 2 ~ 10%, P 2o 5: 1 ~ 3%;
(2) glaze melts the preparation of block: according to above-mentioned raw materials formula, is weighed by raw material and mixes, and puts into and melts kiln high-temperature fusion processed, then drop into Quench in water, pulls the obtained glaze of oven dry out and melts block;
(3) preparation of glaze slip: above-mentioned glaze is melted block and put into grinding in ball grinder with clay, ionogen, pigment, nano titania liquid together with water, obtain glaze slip through sieve series;
(4) burn till: obtained glaze slip is sprayed on surface treated steel baseplate equably, then through 300 ~ 850 DEG C of kiln high-temperature firings, the obtained enamel curtain wall panel with catalytic self-cleaning function.
In sum, the present invention compared with prior art tool have the following advantages:
Preparation method of the present invention, is nano titania liquid and cover-coat enamel burnt till by the design of filling a prescription and high temperature organically to combine, has the advantages such as bonding strength is large, self-cleaning effect good, the life-span is long, uniform color; Adopt the enamel plate that the present invention obtains, the nano titanium oxide on its surface is under the irradiation of sunlight or UV-light, through photocatalysis, create the ability of stronger decomposing organic matter and obnoxious flavour (comprising PM2.5) and destroy the ability of bacterioprotein, therefore there is decontamination, sterilization, the function that purifies air; The present invention also has photochemical catalysis makes plate face contact angle diminish, and improve the hydrophilic effect in plate face, namely the photocatalysis of nano titanium oxide makes surface have Superhydrophilic, and the organic pollutant that plate face is decomposed more easily is cleaned; The effect that the acting in conjunction of above-mentioned two kinds of performances makes enamel curtain wall panel have good self-cleaning, fungus and mildew resistance, purify air, has good economic benefit and social benefit; In addition, in the present invention, because titanium dioxide has been katalysis, itself do not participate in reaction, therefore effect is permanent.
